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.

Ingestible event markers having high reliability are provided. Aspects of the ingestible event markers include a support, a control circuit, a first electrochemical material, a second electrochemical material and a membrane. In addition, the ingestible event markers may include one or more components that impart high reliability to the ingestible event marker. Further, the ingestible event markers may include an active agent. In some aspects, the active agent, such as a pharmaceutically active agent or a diagnostic agent may be associated with the membrane.

A device for gathering data has first and second electrodes. The first electrode is coupled to a surface of interest, and the second electrode is coupled to “everything else” or “the air”. The first electrode is shielded from the second, and from most sources of parasitic capacitance, by a shield that is driven by an active driver that drives the shield to track, and ideally to match, the instantaneous potential of the electrode. The second electrode is likewise shielded in a similar way from most sources of parasitic capacitance. These shields likewise help to limit the extent to which RFI from the device electronics couples with either of the electrodes. In this way the sensing device achieves a markedly better signal-to-noise ratio at frequency bands of interest.

A computer-implemented method is disclosed. The computer-implemented method comprises receiving, by a computer system, ingestible event marker (IEM) system information from a receiver worn by a subject, the IEM system information comprising information associated with ingestion of medication by the subject, wherein the receiver is configured to communicate with the computer system; receiving, by the computer system, contextual information associated with the subject; and calculating, by the computer system, a composite risk score based on the IEM system information and the contextual information associated with the subject.

摘要:
A system for tracking a product from origin to destination is disclosed. The system includes a probe that comprises two plates, a power source and a processor. The power source is controlled by the processor to produce an oscillating output at the plates. Using the oscillating voltage, the probe interrogates a device through capacitive coupling. The device includes a control unit, a memory unit, and first and second materials physically associated with the device for communication using capacitive coupling. Information associated with the device is transferred from the device to the probe through capacitive coupling between the first and second materials and the first and second plates, respectively.
