A wireless sensor network at a monitored location can be configured to generate sensor channel(s) of data to assess operational conditions at the monitored location. Inputs based on the sensor channel(s) of data are provided to a host system for analysis of a demand to one or more resources at the monitored location. Response messages can be generated based on the demand analysis and transmitted to actuator(s) at the monitored location to effect an adjustment to the operational conditions.

A system for manufacturing an antenna includes a first stamping station, a pressure sensitive adhesive (PSA) alignment station, a bonding station, a second stamping station, and a ferrite shield station. The first stamping station receives a sheet of metallic material and stamps the sheet to form an antenna including traces, contacts, a carrier connected to the traces, and a tie-bar connected between the traces. The PSA alignment station receives the stamped antenna and aligns a PSA area of a pad with the traces, the PSA area being substantially the same shape as the traces. The bonding station bonds the PSA area to the traces after it has been aligned with the traces. The second stamping station performs a second stamping of the antenna and the PSA area to remove the carrier and the tie-bar. The ferrite shield station bonds a ferrite shield to the antenna stamped for a second time.

An electronic device may be provided with wireless circuitry that includes antenna structures used to determine the position and orientation of the electronic device relative to external wireless equipment. The electronic device may include a housing having a planar conductive layer, a first slot antenna that includes a first bent slot element in the planar conductive layer, and a second slot antenna that includes a second bent slot element in the planar conductive layer. The first and second bent slot elements may be configured to receive radio-frequency signals at the same frequency. The first and second bent slot elements may have the same shape. The electronic device may include control circuitry configured to measure a phase difference between the radio-frequency signals received by the first and second slot antennas. The control circuitry may identify an angle of arrival of the received radio-frequency signals based on the measured phase difference.

An RFID tag is provided as a wireless communication device that transmits and receives a communication signal. The RFID tag includes a base material, a conductor pattern including an antenna pattern provided at the base material, and a discharge auxiliary electrode. The discharge auxiliary electrode is disposed at a position where the discharge auxiliary electrode overlaps or is close to the antenna pattern in planar view, and lowers a dielectric breakdown voltage between two different opposed portions on the conductor pattern. With this configuration, ignition and combustion is prevented even in a situation in which the RFID tag is subjected to high-frequency power for heating a food item while attached to the food item.

A system and method for tracking medical articles, each having an RFID tag. The articles located in an EM shielded container that includes a probe that comprises a main conductive element having capacitive coupling across a slot to form an electric field and spacing above a ground plane to form an equally strong or stronger magnetic field, both fields filling the interior of the container to activate RFID tags therein. A parasitic element controls the energy pattern of the probe.

Introduced here is an ingestible device comprising a capsule having a central axis therethrough, at least one propulsion component, and at least one motor configured to supply motive power to the propulsion component(s). The propulsion component(s) may be disposed at locations radially offset from the central axis. Upon receiving input indicative of a request to alter a position and/or an orientation of the ingestible device, the motor(s) can supply motive power to some or all of the propulsion component(s) to cause movement of the ingestible device.

Introduced here is an ingestible device comprising a capsule, a camera, an antenna, and a propulsion component. The camera can capture images of various in vivo environments as the ingestible device traverses the gastrointestinal tract, and these images can be wirelessly transmitted to an electronic device located outside of the living body. The images may be transmitted to the electronic device for review by an operator responsible for controlling the ingestible device.
