NOVELTY - A movable coupling between an electronic device and an arm attachment mechanism (440) enables the electronic device to move in a straight line from a wrist adjacent position under the user's shirt sleeve to a palm adjacent position where the electronic device can be manipulated by the hand, while the arm attachment mechanism serves as a cantilever support.    USE - Used as e.g. physical therapy device, solar energy collector, automobile dashboard. Also used as e.g. solar panel of window-mounted air conditioners, optical character reader (OCR) scanning and translating pen, radio frequency (RF) wireless mouse with laser pointer, tag reader, RF identification (RFID) reader, roof-mounted photovoltaic solar panel, network tester, megohmmeter, nose hair trimmer, arm-wearable bar code scanner, digital manometer, ultrasonic hardness tester, battery energy gauge, bar code scanner/RFID interrogator, digital video recorder, personal dictation machine, personal digital audio recorder/dictation machine, computer.    ADVANTAGE - Deters motion without applying pressure to wrist or bones of hand, particularly to carpal tunnel area. Deters but not prevent motion and does not provide resistance to flexor muscles of hand and fingers to allow user to continue to build up hand and forearm muscles. Provides solution to carpal tunnel syndrome that is non-invasive, inexpensive, low-risk, adjustable to fit many different hand sizes, inflatable and reusable.    DETAILED DESCRIPTION - The arm attachment mechanism may include a picture frame-like display (441) into which paper panels bearing bar codes (442) can be removably inserted. A bar code scanner stylus (443) is tethered to the arm attachment mechanism through an electrical cable (444), and can be removably inserted into a clip (445) when not in use. INDEPENDENT CLAIMS are also included for the following:    (a) a method of screening telephone calls;    (b) an automobile cabin air purification system; and    (c) a physical therapy device.
