A bovine monitoring system may include a rumination sensor, a motion sensor, a posture sensor. The rumination sensor may detect chewing by sensing jaw motion. The motion sensor may detect motion. The posture sensor may detect orientation of the bovine asset through detection of gravitational acceleration, detection of gyroscopic rotation, or a combination of gravitational acceleration and gyroscopic rotation. Using the recorded rumination, motion, and posture sensors, the bovine asset monitoring system may identify aberrations in the estrous cycle or physical or mental health of the bovine assets. A bovine monitoring system may include a thermal scanning device to detect localized heating of the vulva area of the bovine asset, which may be used to identify aberrations in the estrous cycle or physical or mental health of the bovine assets.

Methods and systems for detection of removable vehicle seats may be used to indicate presence or absence of a child in the vehicle. In some examples, an alarm system includes a radio frequency (RF) transceiver and a removable seat magnetic coupling. Various actions are triggered when the parent (e.g., guardian) goes beyond a predefined range while the removable seat is within the vehicle, such as sounding an alarm on a mobile electronic device.

Systems and methods for removable vehicle seat sensor

A method includes receiving a transmitted signal containing an object identifier at multiple dispersed antennas, and utilizing inverse Kriging to identify a probable location of each object within a reception area. An object being tracked may detect an event, generate a communication indicative of the event and an object identifier, and transmit the communication to multiple receivers to identify a location of the object.

Real time location system and method

A system includes a microprocessor that executes microcode designed to query all or some of the electronic circuits that are on a device under test. The results of the query are written to an RFID IC register. The RFID IC is queried by an interrogator to obtain test results.

Board test system and method

A delay locked loop generates a voltage on a common node as a function of a phase difference between a reference input and a feedback input. A first voltage-controlled delay line coupled between the reference input and the feedback input and has a first delay, which is controlled by the voltage on the common node. A second voltage-controlled delay line is selectively coupled in series with the first delay line, between the reference input and the feedback input, as a function of a test control input. The second delay line has a second delay, which is controlled by the voltage on the common node.
