Abstract:
The system of the present invention includes a conductive element, an electronic component, and a partial power source in the form of dissimilar materials. Upon contact with a conducting fluid, a voltage potential is created and the power source is completed, which activates the system. The electronic component controls the conductance between the dissimilar materials to produce a unique current signature. The system can also measure the conditions of the environment surrounding the system.
Abstract:
Provided is an apparatus, system, and method for stabilizing battery voltage of a battery device while optimizing power delivered to a receiver during communication of a broadcast packet. A logic circuit is configured to receive a broadcast packet having a predetermined number of bits for communication by a controller to a receiver located remotely from the controller, determine a number of cycles in which a sampled battery voltage is either greater than or less than or equal to a nominal battery voltage over a first subset of the predetermined number of bits of the broadcast packet and performs either a tune-up or a tune-down procedure based on the number of cycles counted in which the sampled battery voltage is not equal to the nominal battery voltage for more than one half of a total number of cycles counted.
Abstract:
Provided is an electronic device having a control device, a driver circuit coupled to the control device. The driver circuit is configured to alter conductance. A partial power source is coupled to the control device and is configured to provide a voltage potential difference to the control device and the driver circuit as a result of the partial power source being in contact with a conductive fluid. The partial power source includes a first material electrically coupled to the control device and a second material electrically coupled to the control device and electrically isolated from the first material. An inductor is coupled to the driver circuit. The driver circuit is configured to develop a current through the inductor. The magnitude of the current developed through the inductor is varied to produce an encoded signal that is remotely detectable by a receiver. Receivers to receive and decode also are disclosed.

Abstract:
Systems, methods, and apparatuses are presented for resolving any interference, noise, and/or collisions caused by two or more ingestible event markers (IEMs) transmitting simultaneously or concurrently. Methods include techniques from the perspective of the IEM for randomly varying signal transmission characteristics in order to avoid collisions with other concurrently transmitting IEMs. Methods also include techniques from the perspective of a receiver for receiving multiple transmission signals from multiple IEMs and for resolving any interference or signal collisions.
