The IMES control unit is capable of allocating total available bandwidth across the number of implants in the system, and supports up to 16 implants on an individual base station. By using multiple implants, it is possible to use machine learning and pattern recognition techniques to estimate movement intent.
The sensor circuit is supplied with constant current. A distinguishing feature of the IEPE principle is that the power supply and the sensor signal are transmitted via one shielded wire. Most IEPE sensors work at a constant current between 2 and 20 mA. A common value is 4 mA. The higher the constant current the longer the possible cable length.
A pet fence or radio fence, is an electronic system designed to keep a pet or other domestic animal within a set of predefined boundaries without the use of a physical barrier. A mild electric shock is delivered by an electronic collar if its warning sound is ignored. The system was first invented and patented by Richard Peck in 1973. [1]
Eye-trackers measure rotations of the eye in one of several ways, but principally they fall into one of three categories: measurement of the movement of an object (normally, a special contact lens) attached to the eye; optical tracking without direct contact to the eye; measurement of electric potentials using electrodes placed around the eyes.
