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.

Abstract: Systems and methods for facilitating interactions between a robotic arm and a movable platform using radio frequency (RF) co-localization are provided. The systems include target devices; an interrogator system comprising RF antennas, each of the RF antennas configured to transmit RF signals to the target devices and/or receive RF signals from the target devices; and a controller. The controller is configured to control at least one of the RF antennas to transmit one or more first RF signals to a target device coupled to a movable platform; control at least some of the RF antennas to receive second RF signals from at least the target device; determine a position of the movable platform using the received second RF signals; and determine, using the position of the movable platform, a target position to which to move an end effector of a robotic arm in order to perform a task.

Abstract: Described herein are techniques for determining motion characteristics (e.g., position, velocity, acceleration, etc.) of one or more trains traveling along a train track, such that train control systems may have the information needed to safely operate the trains at higher speeds and with shorter separation between trains. In accordance with various embodiments, systems and methods described herein may be configured to determine a position, velocity, and/or acceleration of a train traveling along a train track. In some embodiments, the motion characteristics may be determined one or more radio frequency antennas onboard the train, such as in communication with one or more anchor nodes positioned adjacent the train track. Alternatively or additionally, in some embodiments motion characteristics may be determined using one or more one or more inertial measurement units (IMUs) onboard the train.

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.
