4 October 1994 Three-channel telemetry system with optical interface
Author Affiliations +
An optical interface was incorporated into a three channel telemetry device to allow for communication to a packaged telemeter. Information transmitted on the optical link includes calibration parameters and commands to program the operation of the telemeter. The optical ink allows calibration information to be programmed into a telemeter, without the need for a bio-compatible electrical connection. The optical link was designed to completely reside on an integrated circuit chip. One of the three channels of the telemeter is dedicated to temperature measurement, while the other two channels are generic. The generic channels carry information from transducers that are interfaced to the system through on-chip general purpose operational amplifiers. The calibration information that is programmed into the telemeter is retrieved by time division multiplexing it with one of the generic channels.
