Abstract

A system and ingestible boluses for monitoring physiological parameters of animals. The boluses include circuitry for storing a selectable identification code, for sensing a physiological parameter, and for transmitting a data burst signal which includes information corresponding to the identification code and a sensed physiological parameter. In addition to the boluses, the system includes a receiver for receiving data burst signals transmitted from the boluses. According to one mode of operation, the bolus transmits data burst continuously at a preselected rate. The receiver can be coupled to a processor which can process data from the data burst signals.
