Abstract: A system for tracking position of objects in an industrial environment includes an interrogator, a transponder, and a processor. The interrogator transmits a signal and provides a first reference signal corresponding to the transmitted signal. The transponder provides a response signal. The interrogator receives the response signal and provides a second reference signal corresponding to the response signal. The processor determines a location of either the interrogator or the transponder, relative to the other, based on the two reference signals.

Abstract: A system comprising synchronization circuitry, a first interrogator, and a second interrogator. The first interrogator includes a transmit antenna; a first receive antenna, and circuitry configured to generate, using radio-frequency (RF) signal synthesis information received from the synchronization circuitry, a first RF signal for transmission by the transmit antenna, and generate, using the first RF signal and a second RF signal received from a target device by the first receive antenna, a first mixed RF signal indicative of a distance between the first interrogator and the target device. The second interrogator includes a second receive antenna, and circuitry configured to generate, using the RF signal synthesis information, a third RF signal; and generate, using the third RF signal and a fourth RF signal received from the target device by the second receive antenna, a second mixed RF signal indicative of a distance between the second interrogator and the target device.

Abstract: Systems and methods for facilitating interactions between a medical device (e.g., an imaging device, a surgical tool, a robotic arm, etc.) and a patient using radio frequency (RF) co-localization are provided. The systems include a radio-frequency (RF) interrogator system, one or more first RF target devices for coupling to a patient support for supporting a patient with respect to whom a medical device is to perform a task, and one or more second RF target devices for coupling to the medical device. A controller determines a position of the patient support within an RF interrogator system reference frame, a first position of the medical device within the RF interrogator system reference frame, a transformation between the RF interrogator system reference frame and a patient support reference frame, and a second position of the medical device within the patient support reference frame.
