Abstract: A prosthetic device is controlled based on measured electrical signals corresponding to muscle activity in a lower-extremity anatomical analog to a dysfunctional or absent portion of an upper extremity of an individual. In particular, an activity monitoring device measures electrical signals corresponding to muscle activity in the lower-extremity anatomical analog. Then, a communication device communicates information specifying the electrical signals to a pattern-recognition device. The pattern-recognition device identifies a natural mode of movement of the lower-extremity anatomical analog based on the information. For example, the natural mode of movement may be identified using a pattern-recognition technique.

Abstract: Improved apparatus and methods of sensing or monitoring body orientation and motion and measuring range of motion (ROM) for use in athletic training and physical rehabilitation and evaluation. The apparatus includes a 3-axis sensor, at least one memory, and at least one processor, and is attachable to an object to be monitored. The 3-axis sensor senses a magnitude of tilt along each of a first, second, and third axis, the memory stores data representing the sensed magnitudes of tilt, and the processor processes the data stored in the memory. In one embodiment, the processor determines an angle between each of the first, second, and third axes and a horizontal plane, and selects the two axes corresponding to the two smallest angles between the three axes and the horizontal plane. The processor then generates an indication of the orientation of the object based upon the sensed magnitudes of tilt along the two selected axes.

Abstract: A message that includes a command for an audio device is received, and the command is transmitted to the audio device.
