US 10,517,508 B2 · Ingestible bio-telemetry communication network and associated systems

Abstract

Ingestible bio-telemetry communication network and associated systems are described. The communication network can include one or more ingestible bio-telemetry tags; and a reader, wherein each of the one or more ingestible bio-telemetry tags generates an out-link signal comprising, for each bit of data in a frame, a pulse reverse keyed symbol. Multiple ingestible bio-telemetry tags can be managed at the same time by allowing the frequency of the transmit carrier signal to change, or “hop” to different frequencies so as to minimize likelihood of collision. A reader can identify the proper frequency either by a signal from the tags indicated the frequency of the next hop or, when no bi-directional communication is available, by deducing the carrier signal frequency from the start bits of a received frame from the tag and scanning for the shifted carrier signal frequency within a tolerance of the deduced carrier signal frequency.

Dependent claims

An ingestible bio-telemetry communication network, comprising:

each of a plurality of ingestible devices configured to obtain data relating to a patient, and transmit the data by bursting bits of the data with a selected gap between pulses in transmission to reduce power, wherein each pulse is repeated one or more times for a given data bit, and a burst pattern of the data is configured to have 50% or more burst density, wherein the pulses transmitted by each of the plurality of ingestible devices have a duty cycle of about 1 to 1000;
and
a receiver configured to be positioned outside the patient's body and receive the data.
