Center for Wireless Aids in Health Care (CWHC)
( Department of Bioengineering, UC Berkeley, Children's Hospital Oakland Research Institute )

1. Our Mission:

      To help millions of handicapped patients to:

        - Perform environmental control efficiently, including lighting, security, heating and cooling systems;
        - Have access to the modern electronics for personal, home and hospital care including cell phone, computers, play station, TV, DVD and etc.


Handicapped patients who will benefit from R&D projects in CWHC:

             - The leading cause of adult disability in USA. 
                 - Ambulation, arm and hand motor function loss, and oral communication disabilities.
             - Over 0.5 million Americans survive strokes each year.
                 - Prevalence is 6 million for various disabilities from motor function loss and communication deficits.
                 - Personalized therapy for stroke caused disabilities consumes 3-4% of the national health budget in the US (NIH data).

           - The annual incidence is 12,000; prevalence is 300,000 in U.S.A. (18 % have high-level SCI that in most compromise upper extremity use).
           - The annual medical cost is 9.3 billion dollars (NSCISC 2004).

-                  - Incidence of 320,000 per year, U.S.A.

-                  - Incidence of 2400 per year U.S.A.

-                  - Paralysis except for eye movement (e.g. ALS, 1000 per year)


Supported wireless consumer electronics:

-                  - An incomplete list of commercial available ZigBee home automation certified products we will support.

        -   We will support any PC with Bluetooth hardware.
        -   We will negotiate with Bluetooth based devices (cell phone, play station, etc.) companies to enable access.
        -   Coming soon: a list of commercial available Bluetooth based devices supported by us will be published on our CWHC website.
