Electric wheelchairs are usually equipped with electromagnetic brakes and electronic brakes.

  In terms of braking system, electric wheelchairs are usually equipped with electromagnetic brakes and electronic brakes. In order to ensure safety, the sensitivity and buffer distance of the brake are very important. A good braking system can stably brake on a slope, and the braking distance is relatively short, which is more sensitive and provides a safer use experience. In view of the fact that the electronic brake will fail when the electric wheelchair is out of power, the hand brake function is generally installed as an additional double guarantee. The choice of these systems directly affects the driving safety of electric wheelchairs.contemporaneity 電動輪椅 Our competitors have not made large-scale improvements, so we should get ahead of everyone in the project. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  Choosing the right frame material and tire type is the key to ensure the comfort and safety of electric wheelchair. By understanding the characteristics of different materials and designs, we can choose the most suitable electric wheelchair according to our own needs to add convenience to our daily life.

  

  Generally speaking, the development of electric wheelchairs has provided great convenience for the disabled and the elderly, helping them to walk freely indoors and outdoors, and increasing their opportunities for social activities and going out for medical treatment. Secondly, it provides the ability to move independently. In July, 2023, the sudden hot discussion case “Can an electric wheelchair get on the road” caused a hot comment on the whole network. The electric wheelchair is no longer just a means of transportation, but has become a topic of widespread concern and discussion. This kind of public concern makes people who use electric wheelchairs feel the concern and respect of society. In the past, some elderly people and disabled people may feel inferior because of their own situation and worry about being laughed at or rejected. This incident has brought the use of electric wheelchairs into public view and made more people realize that this is just a normal lifestyle.

  

  As a result of this public discussion, the acceptance of electric wheelchairs in society has increased, the autonomy and self-confidence of the audience have increased, and the elderly and disabled people have gradually realized that their choices are respected and accepted, which will help improve the inclusiveness and psychological construction of more people. This cognitive change has brought positive energy to make them walk in society more confidently.

High-power lasers with superthermal laser crystals

  INTRODUCTIONOnly by working together can we turn high powered lasers that burn The value of the play out, the development of the supply market needs. https://highpowerlaser.shop/collections/burning-laser

  

  Since the birth of the laser in 1960, achieving high output power has been one of the eternal themes in the development of laser technology. The process of increasing laser energy is always accompanied by thermal energy, and thermal energy is useless in this process, “laser energy” and “thermal energy” are the highest and lowest quality forms of energy respectively, and the history of the development of high-power laser technology is a history of struggle with “waste heat”.

  

  The first ruby laser[1″ target=_blank> that marked the birth of lasers in 1960 was a solid-state laser. Solid-state lasers usually use activated ion-doped crystals, ceramics and glass as the gain medium, and their gain medium forms include conventional bulk materials and low-dimensional materials represented by optical fibers. After the birth of solid-state lasers, on the one hand, the wavelength coverage was expanded, from the initial red light to short-wave green light, blue light, ultraviolet, deep ultraviolet development, long wavelength

  

  Lasers have matured and commercialized in the near-infrared and mid-infrared bands, and on the other hand, the laser pulse width has been narrowed from microseconds (μs) to nanoseconds (ns), picoseconds (ps), and femtoseconds (fs), and attosecond (AS) lasers are expected to be engineered [2-3″ target=_blank>. The realization of high output power in any application scenario is the common goal of laser technology development [4-6″ target=_blank>.

  

  With the increase of pump power, the thermal effect inside the gain medium is significantly enhanced, and the heat generated cannot be removed from the medium in time through heat conduction, resulting in an increase in the internal temperature and temperature gradient of the medium, and the thermal lensing effect and stress birefringence effect caused by the internal thermal distortion seriously deteriorate the beam quality and limit the further increase in power [7″ target=_blank>. In order to suppress the thermal effect, researchers have designed different types of solid-state lasers, such as heat-capacity lasers, thin-slice lasers, slat lasers, and fiber lasers [8″ target=_blank>, with the core idea of improving heat dissipation efficiency. In this paper, the working characteristics and research progress of the above solid-state lasers are briefly reviewed. In addition, based on the current theoretical and experimental research on the thermal conductivity (κ) of crystalline materials, from the perspective of improving the thermal conductivity of gain dielectric materials, the thinking and prospect of solving the thermal effect problem are proposed.

  

  1 High-power lasers

  

  1. 1 heat capacity laser

  

  Heat-capacity lasers reduce the thermal distortion of gain materials by separating the working phase of the laser from the heat dissipation phase in time. When the heat capacity laser is working, the gain medium is in an approximately adiabatic environment, and its internal temperature gradient is small, and the resulting thermal distortion is also small. The internal accumulation of waste heat increases the temperature of the gain medium, which must be forced to cool after a period of continuous operation, depending on the thermodynamic properties of the material itself. Because the gain medium does not dissipate heat from the outside during the laser operation stage, its surface temperature is higher than that inside, and the compressive stress on the surface can greatly increase the damage threshold of the medium, and the allowable laser pumping strength is 5 times that of the surface in the state of tension. The output of a heat-capacity laser depends on the product of the gain medium and the temperature range of the laser that it can generate, so it is not only required that the gain dielectric material have a large heat capacity value, but also that the luminescence efficiency of the internally activated ions is less affected by the increase in temperature [9″ target=_blank>.

  

  As early as 1994, Walters et al. [10″ target=_blank> used a heat-capacity laser with flash-pumped rod-shaped neodymium glass as the gain medium to achieve a pulsed laser output with an average power of more than 1 kW and a duration of several seconds, proving the feasibility of the heat-capacity laser scheme. Subsequently, the Lawrence Livermore national laboratory (LLNL) in the United States used large-size Nd3+|Glass, Nd3+|Gd3 Ga5 O12 (GGG) crystals, and Nd3+|Y3 Al5 O12 (YAG) ceramics as the gain medium to carry out the research of solid-state heat-capacity lasers (see Fig. 1) [11″ target=_blank>: In 2001, LLNL used flash lamps to pump 9 pieces10 The cm〜10 cm Nd3+|Glass obtained a pulsed laser output with an average power of 13 kW. In 2004, LLNL used a laser diode array to pump four 10cm〜10 cm Nd3+:GGG crystals to achieve 45 kW laser output. In 2006, LLNL used a laser diode array to pump five 10 cm 〜 10 cm Nd3+:YAG ceramics with an output power of up to 67 kW and a pulse duration of 500 ms. By introducing a real-time adaptive optical correction system in the cavity, the beam quality control was within 2 times the diffraction limit, and the laser running time was increased to 5 s [12″ target=_blank>.

  

  Heat-capacity lasers have two important limitations: (1) the laser beam quality degrades rapidly with the increase of light generation time [13″ target=_blank>; (2) The cooling time of the gain medium accounts for 80% of the entire working cycle, which determines that the heat capacity laser cannot work at high frequency, and the working time in seconds is difficult to meet the practical requirements.

  

  1. 2 thin-slice lasers

  

  The gain medium of the thin slice laser is a thin sheet with a thickness of less than 1 mm, which is fixed to a rigid substrate that dissipates heat by solder, and the bottom surface of the contact acts as a cooling surface and also acts as a reflective surface for the laser and pump light, and the other side acts as a high transmission surface. Since the direction of heat flow and the direction of laser propagation are basically the same, the wavefront distortion caused by the temperature gradient can be largely ignored, resulting in a high beam quality laser output. The advantage of thin-slice lasers is that they maintain high beam quality at high power outputs. Thin-slice lasers are available in two types of pumping methods: end-pumping and side-pumping, as shown in Figure 2 [14″ target=_blank>.

  

  Due to the short propagation distance of light in a single sheet, the gain capacity is limited, and the maximum output power is currently 5 kW [15″ target=_blank>, and further power increases require the cascade of multiple lamella for amplification (see Figure 3 [16″ target=_blank>). In 2000, Stewen et al. [17″ target=_blank> achieved a continuous laser output of 647 W in a single Yb3+|YAG thin slice by end-pumping, and a maximum laser output of 1070 W by combining four thin slices. In 2009, the Boeing Company pumped 10 Yb3+:YAG thin slices to obtain a laser output of 28 kW, with a laser duration of several seconds and a beam mass close to the diffraction limit [18″ target=_blank>. The commercial thin-slice laser developed by Trumpf in Germany is capable of producing a continuous laser with a stable output power of 18 kW. Theoretical calculations show that the maximum output power of a single sheet is about 30 kW [15″ target=_blank>, and it is clear that the current experimental results are still quite far from the theoretical value.

  

  At present, the main problems of thin slice lasers are: (1) high requirements for crystal thin slice processing and welding process; (2) The gain capacity of a single sheet is limited, and the cascade of multiple pieces will make the optical path of the system extremely complex, which requires high precision assembly and adjustment ability of the system.

Common sense of using electric wheelchair scooter for the elderly

  The development trend of electric wheelchair and old scooter is portable, and the lighter the electric wheelchair, the more convenient it is. However, there will be some wrong operations when the elderly choose or use them, which will often cause unnecessary problems and avoid unnecessary injuries caused by improper operation.So, I believe 電動輪椅 In the future, it will be promising to create a miracle belonging to the industry. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  First, the driving operation is not standardized: the elderly and disabled people sometimes appear in the fast lane and ignore the traffic lights when driving electric wheelchairs and old scooters. This is a very dangerous operation, because the speed of electric wheelchairs and old scooters is very slow, and the speed is generally not more than 10 kilometers per hour. Driving an electric wheelchair scooter on the fast lane will cause traffic congestion, and in the worst case, it will cause a serious traffic accident. You must not drive on the motor vehicle lane, and you should drive on the sidewalk or non-motor vehicle lane.

  

  Second, electric wheelchairs and old scooters need daily maintenance, especially before use, the power and tires must be checked, and the welding points of the frame and the tightness of each screw need to be checked every once in a while. Electric scooter had better keep the battery fully charged at any time, and charge it as needed. Frequent power loss will lead to the reduction of power storage capacity. There are still many people who blindly pursue cruising range and driving speed when purchasing electric wheelchairs and old scooters. In reality, it should be chosen according to the user’s normal range of activities. If the range of activities is small, it is not necessary to choose an old scooter with too large battery capacity.

  

  Third, in the process of selling electric wheelchairs and elderly scooters, many elderly people often choose portable folding electric wheelchairs for convenience. In fact, this is a serious misconception. We always guide the elderly not to move electric wheelchairs, scooters and so on. Even if it is difficult to pass, it is recommended to get off and pass. If you encounter steps on the road, it is best to ask your family or passers-by for help. It is not recommended for the elderly to move it by themselves, because the lightest folding electric wheelchair weighs about twenty or thirty kilograms. This weight is also very heavy for the elderly, and if you move it by your own strength, it may lead to unnecessary injuries such as waist fractures.

Laser pointer shopping guide

  As the saying goes, “if you want to do a good job, you must first sharpen your tools”, when you want to go on stage to give a wonderful PPT explanation or teaching, in order to let the audience clearly grasp the progress position of what the narrator says, the guidance of the laser pointer is indispensable. However, there are not only a variety of styles that compound the functions of the briefing machine and mouse in the laser pointer products, but also common red light and professional-grade green light and blue light in terms of light color, so it must not be easy to buy.As it happens, many people are killed purple laser And bring more benefits, make it flourish, and promote the industry greatly. https://highpowerlaser.shop/collections/frontpage

  

  Therefore, this article will take you to understand the purchase skills of laser pointers, whether you want to find a style for presentations, or need a higher power industrial laser pointer, as long as you can find the most suitable product after reading this article, let’s read down to take a look!

  

  Benefits of using a laser pointer:

  

  When teaching and giving presentations on the podium, it is usually necessary to use auxiliary props such as laser pointers, so that the audience can clearly know where the content mentioned is on the PPT. However, many people who are looking for convenience and speed will choose to use their hands or long instruments such as batons to instruct, but laser pointers also have many irreplaceable advantages.

  

  First, when the screen is too large or inconvenient to move around on stage, the hand and stylus may not be able to reach every corner of the frame, while the laser pointer can easily reach all the beams. In addition, when using a finger or a command pen, it is inevitable that part of the picture will be obscured by the shadow of the body, and the dotted laser pointer ensures that the audience can see the full text and graphics of the presentation.

  

  In addition, when using a projector or or other device to make a report, it is common to turn off light sources such as electric lights to make the projected image clearer, but at the same time, the narrator’s movements become difficult to read due to the darkness, and the laser pointer can be clearly seen in a dimly lit environment. Therefore, it is recommended that all commentators buy a laser pointer in case of emergency, which will not only be more flexible in the way of use, but also greatly improve the accuracy of the report.

  

  Key points for choosing a laser pointer

  

  Next, we will explain what to consider when choosing a laser pointer, and whether you are buying from a physical store or an online store, you can find a product that meets your needs by checking the following points.

  

  1. Think about the color of the light first

  

  Laser pointers are mainly divided into red and green depending on the wavelength of the light, and although there are other colors such as blue light on the market, the following details the differences between the most common red and green colors.

  

  1.1 Red light: high popularity, relatively affordable and easy to get

  

  The red light type must be the most familiar laser pointer style in everyone’s impression, because of its cheapness, many styles and high popularity, it is very suitable for people who want to start quickly, in addition, the red light type due to low power consumption, a single battery can be used for a long time and is not easy to cut off, it is quite recommended to use people with high frequency to buy.

  

  However, compared with green light, red light is not easy to project on screens such as plasma TVs, and its visual sensitivity and irradiation distance are also unsatisfactory, but it is more than enough for use in small spaces in classrooms or conference rooms.

  

  1.2 Green light: suitable for large, bright spaces

  

  Green light has high visual sensitivity and a long projection distance, and there are even high-performance models with a range of up to 200~300m on the market, so it is more stable for people who often use it in large conference rooms and lecture halls. However, due to the complexity of the structure, the average price is higher than that of the red light model; However, if you buy a cheap model, problems such as unstable beam output may occur, so it is recommended to compare the performance of each product when buying a green laser pointer to avoid mistakes.

  

  2. The shape affects the feel when using

  

  Laser pointers have a variety of styles to choose from depending on the shape, and it is recommended to evaluate the suitable products according to personal usage habits. For example, users who prioritize portability can choose a small pen type or key ring type; If you are concerned about the freedom of your hands when using it, you can choose a ring that can be fastened to your finger like a ring; For those who value grip, there is a special shape that enlarges the grip to match the shape of the palm.

  

  However, when considering the feel, we should not ignore the disadvantages that come with it, such as the light source of the ring model is usually weak, and the style with a large grip will be bulky overall, so it is important to evaluate the balance of the advantages and disadvantages of the product when purchasing in order to find the most ideal product.

  

  3. Diverse accessibility features

  

  In addition to the models that simply have the function of an indicator light, there are also models with a variety of wireless technologies that can improve the smoothness of reporting.

  

  3.1 Presentation function: easily switch PPT pages

  

  Many occasions that use laser pointers to report will be operated together with PowerPoint (referred to as PPT) and other presentation software, at this time, if you choose a model with wireless technology, you can freely turn the page, so that the process of reporting can be more easily explained and freely interact with the audience without the scope of the computer.

  

  3.2 Mouse function: free operation of the computer

  

  If you have to operate the computer to play videos and open Excel spreadsheets from time to time, it is recommended to choose a laser pointer with mouse function, because it can freely click and slide the page, which can greatly reduce the rhythm of the report caused by operating the computer. Although this type of product has a large number of buttons and takes time to get started, it can be a great tool for presentations after getting used to the interface.

  

  4. Confirm the range of wireless signal reception

  

  If you intend to use the additional functions described in the preceding paragraph, the signal is usually connected by a USB wireless receiver or Bluetooth, and in order to ensure a smooth and uninterrupted signal between the laser pointer and the computer, it is important to confirm the signal reception range of the product when purchasing the relevant product.

  

  Most of the signal range in commercial products falls between 10m~30m, so if you plan to use it in a large conference room, it is recommended to choose a wide range of models. In addition, the Bluetooth model usually has a large signal reception range, and even a long-distance product of up to 50m can be found, if you can’t confirm the size of the site before arriving at the site, or often operate the laser pointer in different scale locations, you must be able to use the Bluetooth laser pointer more securely.

  

  5. CNS mark: to ensure product safety

  

  Since the laser pointer is made to be recognized by the human eye by projecting a high-power concentrated beam, if it is directly irradiated to the eye, there will be a risk of blindness, so it is important to choose a model that has been inspected by the Bureau of Standards, Inspection and Inspection of the Ministry of Economic Affairs and passed the national standard (CNS, also known as orthography) when purchasing.

  

  Generally speaking, the power of laser pointers for presentation on the market is limited to laser class 2 and 1mW, but if it is used for advanced applications such as engineering and stargazing, there are also products with higher power on the market, so it is recommended to select products according to individual use purposes. If you only need to use it in small spaces such as classrooms and conference rooms, you can reduce the risk to humans by choosing products with safety signs.

  

  summary

  

  In order to complete a perfect briefing, a laser pointer that can make a point is indispensable. By reading the key points of this article, I believe you have gradually clarified what products are suitable for you. I wish everyone can choose the right laser pointer for you.

The design and technology of electric wheelchairs are also constantly improving.

  With the progress of science and technology, the design and technology of electric wheelchairs are constantly improving. In the 1960s, electric wheelchairs began to use rechargeable batteries, which made them last longer and charge more conveniently. In the 1970s, the materials and structures of electric wheelchairs began to be improved, making them more portable and stable. In 1980s, with the development of computer technology, intelligent control system was introduced into electric wheelchairs, which made the wheelchairs operate more accurately and the user experience better. In addition, the battery technology of electric wheelchairs has also made a revolutionary breakthrough.In the past ten years, 電動輪椅 Defeated many competitors, courageously advanced in the struggle, and polished many good products for customers. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  The traditional lead-acid battery is gradually replaced, and the new lithium battery and fuel cell technology are applied to electric wheelchairs, which greatly improves the endurance and service life of wheelchairs. These technological innovations not only make electric wheelchairs more environmentally friendly, but also provide users with longer use.

  

  The types of electric wheelchairs are becoming more and more abundant. According to different functions and usage scenarios, electric wheelchairs can be divided into indoor electric wheelchairs, outdoor electric wheelchairs, folding electric wheelchairs and many other types. Indoor electric wheelchairs are usually small and suitable for use in indoor environments, such as homes and hospitals.

  

  Outdoor electric wheelchairs are more powerful, have better passability, and are suitable for outdoor complex road conditions. The folding electric wheelchair is portable and can be carried and stored conveniently. Modern electric wheelchairs use lightweight aluminum alloy frames, intelligent control systems and high-performance batteries. The application of these technologies makes the electric wheelchair more intelligent, convenient and comfortable.

The color wavelength of the laser pointer knowledge

  Laser pointer, also known as laser pointer, pointer, etc., is a pen-shaped emitter designed to be portable, easy to hold in the hand, and processed into a laser module (diode). Common laser pointers include red (650-660nm), green (532nm), blue (445-450nm), and blue-violet (405nm). It is usually used by newspapers, teachers, and docents to project a point of light or a ray of light directed at an object.In order to open the market, rechargeable laser pointer Constantly improve the ability of business development and create an extraordinary brand image for it. https://highpowerlaser.shop/collections

  

  A physical picture of a common laser pointer

  

  Early laser pointers (HeNe) HeNe gas lasers produce a laser wavelength of 633nm, typically 1mW. The cheapest laser pointers use a deep red laser diode with a wavelength of nearly 670/650nm. Slightly more expensive with red, orange 635nm diodes. Other colors are also possible, with the green laser at 532 nm being the most common alternative. Later, an orange-yellow laser pointer with a wavelength of 593.5 nm appeared. In 2005, a 473nm blue laser pointer appeared, which was introduced in September. At the beginning of 2010, a blue-violet laser pointer with a wavelength of 405 nm appeared.

  

  The brightness of the laser beam on the spot depends on the laser power, the reflectivity of the surface. For the same power, the spectrum of the human eye in the green region (wavelength 520-570nm) is most sensitive and appears to be brighter than other colors. The sensitivity of the wavelength of red or blue decreases.

  

  A laser pointer that typically represents the output power of milliwatts (mW). In the United States, lasers are classified by the National Standards Institute and the Food and Drug Administration (FDA). Visible laser pointers (400-700nm) operate at less than 1mW of power, Class 2 or II, visible 1-5mW laser pointers, are Class 3A or IIIa. Class 3B or IIIb lasers produce 5 to 500 mW; Class 4 or 4 lasers produce more than 500mW. The U.S. FDA regulations state that “demonstration laser products” must meet applicable requirements for Class I, IIA, or IIIA devices.

  Red and orange laser pointers

  

  This is the simplest laser because there are red diodes. No more than one battery-powered laser diode. The first red laser pointer, released in the early 80s of the 20th century, sold for a few hundred dollars. Today, they are much smaller and generally cost very little. Diode-pumped solid-state (DPSS) red lasers at 671nm are common.

  

  Yellow laser pointer

  

  Yellow laser pointers are extremely rare in the market. DPSS technology is obtained by adding two laser beams with wavelengths of 1064 nm and 1342 nm through a nonlinear crystal. The complexity of the process makes the yellow laser pointer unstable and inefficient, with an output power of 1-10mW depending on the temperature, and a pattern jump if it is overheated or too cold. This is because the size of the laser pointer does not provide the required temperature stabilization and cooling parts. In addition, most 593.5nm laser pointers operate in pulsed mode to allow for the use of pump diodes with smaller size and power.

  

  Green laser pointer

  

  The nonlinear crystal is excited by an infrared laser with a wavelength of 808nm to produce 1064nm infrared light, and then 532nm green light is generated by frequency doubling, which belongs to solid-state lasers. Some green lasers operate in pulsed or quasi-continuous mode to reduce cooling problems and extend battery life. Green lasers, which do not require frequency doubling, have higher efficiency. At night, even low-power green light can be seen due to Rayleigh scattering of atmospheric molecules, and this laser pointer is often used by astronomy enthusiasts to point to stars and constellations. Green laser pointers can have a variety of output powers. The 5mW (IIIA) is the safest to use and is also visible in dim lighting, so no more power is required for pointing purposes.

  

  Blue light laser pointer

  

  Blue laser pointers such as a specific wavelength of 473 nm usually have the same infrastructure as green lasers. Many factories in 2006 began to produce blue laser modules, mass storage devices, these used laser pointers. This is the type of equipment that pumps the frequency doubling with semiconductors. They most often emit 473 nm, which is doubled by a frequency multiplied by a diode-pumped laser at 946 nm ND:YAG laser or yttrium neodymium vanadate crystals. The BBO crystal with high output power is used for KTP crystals as a lower power doubling.

  

  Visible wavelength green laser pointer

  

  Some manufacturers are selling indicators of parallel blue laser diodes measuring power over 1500 milliwatts. However, since the claimed power of the “laser pointer” product also includes infrared power (only in semiconductor pumping technology) is still in the beam (for reasons discussed below), the laser is still problematic on the basis of the DPSS-type elements of the more strict visual blue, and is usually not applicable. Due to the use of higher neodymium harmonics, the frequency doubling conversion efficiency is low, and the infrared power is a small fraction of the optimal configuration of the semiconductor pump module, and the conversion of a blue laser at 473 nm is typically 10-13%, which is about half of that typical of green lasers (20-30%).

  

  The blue laser can also directly fabricate indium gallium nitride semiconductors, producing frequency-grabby blue light. There are blue laser diodes on the market (447\5 nm), and the device is a bright same violet laser diode with a power of less than 405 nm, because the longer wavelength is closer to the peak sensitivity of the human eye. The mass production of laser projectors for commercial equipment, such as laser diodes, has driven down prices. The use of popular high-power (1W) 447 nm indicators, which also have improved optical versions of better collimation and lower divergence, comparable to the use of these portable devices, has reduced the sensitivity of green lasers with the intention and cost of human harm.
