Provided is an apparatus for tracking an object. The apparatus includes a grid including a plurality of antennae arranged to form an array of cells in which the object can be tracked, and a communication tag provided to the object to be sensed for tracking a location of the object. A receiver is operatively connected to the antennae for transmitting an interrogation signal via the antennae and receiving a signal indicative of a location of the object within the array in response to transmission of the interrogation signal. A processor unit utilizes the signal to determine useful data indicative of the location of the object in the array, and a platform presents the usable data to a user to relay information about the location of the object.

Systems, methods, apparatuses, and computer readable media are disclosed for providing variable blink rate ultra-wideband (UWB) communications. Some embodiments may provide for a radio frequency (RF) tag including a motion sensor, processing circuitry, and a UWB transmitter. The motion sensor may be configured to generate one or more motion data values indicating motion of the RF tag. The UWB transmitter may be configured to transmit blink data at variable blink rates. The processing circuitry may be configured to receive the one or more motion data values from the motion sensor, determine a blink rate for the UWB transmitter based on the one or more motion data values, and control the UWB transmitter to wirelessly transmit the blink data at the blink rate. In some embodiments, the RF tag may include a UWB receiver and the blink rate may be controlled remotely by a system.

A mobile body specifies a current position of the mobile body with a position specification unit. Further, a detection units detects that the mobile body is in a still state after starting moving from a still state, and a signal containing the specified current position is output to the outside. The mobile body includes a power unit that supplies power to power-consuming units inside the mobile body. The power unit supplies power to the position specification unit during a period from first timing after the mobile body starts the movement to second timing after the mobile body enters the still state.

A process to partition a video feed to segment live player activity includes receiving, on a first recurring basis, a transmission of a central video feed from a first camera. The central video feed is calibrated against a spatial region represented in at least two dimensions that is encompassed by the central video feed. The process includes receiving, on a second recurring basis, a respective time-stamped position information from each tracking device in a plurality of tracking devices. Each tracking device is worn by a corresponding subject on the spatial region and transmits positional information that describes a time-stamped position of the corresponding subject in the spatial region. The process uses the received information and the calibration to define a first sub-view of the central video feed associated with a first subject. The first sub-view comprises a corresponding sub-frame associated with the first subject.
