Other acid DMFC systems have been investigated during the late 1970s and early 1980s for different appUcatimis, such as military communication systems (US Army) and electric wheelchairs (Royal Institute of Technology, Stockholm), and golf carts driven by DMFC in conjunction with lead acid batteries (Hitachi,... 

The spaces recommended in Tables 34.1 and 34.2 generally are adequate for most people who use standard-sized manual or electric wheelchairs. 

The situation in the individual healthcare industry was different as the share of users was very small compared to the sports and leisitre industry. In these industries many of the external users are not part of the active labor force, due to their age or physical constitution. Exceptions are those people who stand out from the whole user crowd due to their personal fitness, being able to work in a company. An example for embedded lead user innovation was a new design for a throttle grip on an electric wheelchair, which could not be grasped by a handicapped employee and was thus being redesigned by him (Health 4).

A bowel program is essential as nothing is more disappointing for the patient than an unwelcome bowel movement after washing, dressing, and being placed in an electric wheelchair. One untimely accident can waste an entire day of rehabilitation. Bowel programs prevent skin breakdown, decrease medical complications, and improve the time spent in rehabilitation activities. 

But in the case of Korea, more than half the items are purchasable. This increases the burden put on the consumer. Also Korea s welfare equipments are more passive meaning that there are hardly any items with electric controllers. Only two such items exist like the electric wheelchair and the electric bed.

Even more power hungry are moving vehicles, such as wheelchairs, golf carts, and carts in poorly ventilated spaces, such as in warehouses, mines, and ship holds. The all-electric automobile that can travel for 300 miles at 60 m.p.h without recharging would be the greatest prize. 

Whenever you start a car, use a battery-powered device, apply a rust inhibitor to a piece of metal, or use bleach to whiten your clothes, you deal with some aspect of electrochemistry. Electrochemistry is that branch of science that involves the interaction of electrical energy and chemistry. Many of our daily activities use some form of electrochemistry. Just imagine how your life would be in a world without batteries. What immediately comes to mind is the loss of power for our portable electronic devices. While this would certainly be an inconvenience, consider the more critical needs of those with battery-powered wheelchairs, hearing aids, or heart pacemakers. In this chapter, we examine the basic principles of electrochemistry and some of their applications in our lives. 

Beryllium (Be) is an alkaline earth metal found in the earth s crust at an approximate concentration of 3 to 5mg/kg it is poisonous and not necessary for human health. Beryllium alloys are lightweight, stiff, and highly electrically conductive. Beryllium as pure metal, Be alloys, and ceramics are used in a wide range of applications, including dental appliances, golf clubs, nonsparking tools, wheelchairs, satellite and spacecraft manufacture, circuit board... 

Lead accumulators are used in various applications, such as starters of internal combustion engines, electric traction (forklifts, wheelchairs, etc.), power generation units (power plants, telephone exchange stations, railroads, hospitals, etc.). 

The applications described in Sections 8.1.7.1 to 8.1.7.3 are expected to have the potential to become high volume products. However, numerous niche applications with more relaxed cost requirements as compared to the mass markets are available. Electric power can be provided where there is no electric grid connection such as for light transportation (electric bikes, wheelchairs), as auxiliary power units (trucks, boats), remote area power supply (mountains, camping), for appliances (lawn mower, vacuum cleaner), for military and defence purposes, space travel or for electric grid back-up where availability is crucial (telecommunication, computing).

There are two basic classes of wheelchairs manually powered and externally powered. For practical purposes, externally powered wheelchairs are electrically powered wheelchairs. There are approximately 200,000 wheelchairs sold annually within the United States of which about 20,000 are powered wheelchairs. Most wheelchairs are purchased by third-party-payers (e.g., insurance companies, government agencies). This requires the market to be responsive to wheelchairs user s needs, prescriber expertise and experience, third-party-payer purchase criteria, and competition from other manufacturers. Despite the complicated interaction between these components, and the regulation of products by several government agencies, a variety of wheelchairs and options are available. 

HSCs are used as tractive power sources in electric buses, wheelchairs, and trolleys and in lanterns. Besides, it is planned to be used in portable devices (radio telephones, camera recorders, players), and so on. One of the advantages of HSCs as compared... 

People who use electric scooters for mobility will require more space to maneuver because most scooters are much less maneuverable than a power wheelchair.
