    摘要： An aspect of the invention is a liquid sensor having a galvanically energizable power source capable of activating a remotely detectable signal in response to liquid. In a preferred embodiment, a liquid sensor includes a plurality of electrodes, a circuit, and a transmitter thereon. The electrodes are coupled to generate electrical power when in contact with liquid. The circuit is electrically connected to the electrodes so as to be activated by the electrical power, detect an electrical parameter of the electrical power, and generate a plurality of data packets indicating a degree of wetness corresponding to the detected electrical parameter. The transmitter is electrically coupled to the circuit to receive the plurality of data packets and transmit representations of the plurality of data packets as electromagnetic signals. Other aspects include a liquid absorbent wetness sensor and a computer-based wetness monitoring system, and method of detecting liquid.

    摘要： 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.
