Abstract: Provided are implantable devices for communicating with biological tissue and methods and systems for using the devices. For example, the devices are implanted in a subject and used to communicate with regenerated neural tissue.

Abstract: Weight-shift activity is measured by small, flat, low-cost pressure sensors placed under the cushion in the seat of the wheelchair. A wireless communications device such as a Blackberry™ page processes data received from the pressure sensors and transfers the electronic records to a central database periodically or in near real-time. The information about activity and weight shift exercises is stored at the central database where it may be accessed and viewed by Internet users. Historical records of an individual's activity may be presented to the individual and authorized caregivers through secure web pages. This activity information will encourage the wheelchair user to perform regular weight shift exercises and will allow caregivers to intervene when high-risk periods of inactivity are detected.

Abstract: A system for enabling a user to exert control with bioelectrical impulses via an input from the user includes a first electromyogram interface, a computer display and a computer. The first electromyogram interface to the user is in communication with a first source of bioelectrical impulses from the user. The computer display is capable of displaying a cursor. The computer is in communication with the electromyogram interface and the computer display, and is programmed to sense a first input from the first electromyogram interface, change a first computer control attribute in response to a state change sensed in the first input, and generate a preselected cursor action in response to a change in the first computer control attribute.
