  • Publication number: 20210337103
    Abstract: An apparatus comprises a mount body by which the apparatus is secured to a structure. A camera assembly includes an image sensor adapted to capture images within its field of view. A lighting assembly houses one or more light sources including a directional light source. A control-board assembly, fixed to the mount body, houses control boards including one or more processors configured to acquire information about an object, to associate a location within the field of view of the image sensor with the object, to point light emitted by the directional light source at the location associated with the object by rotating the lighting assembly and turning the laser assembly, and, based on an image acquired from the camera assembly, to detect change within the field of view of the image sensor corresponding to placement or removal of the object.

  • Patent number: 10631131
    Abstract: Systems and methods improve virtual reality and augmented reality functionality for mobile devices using radio frequency (RF) signals transmitted by a tracked device and received at four or more spatially separated antennae. These antennae are connected, wirelessly or through wired connections, to a base station. Through RF signal time of arrival information acquired at the antennae, the base station can continuously determine accurate position information of the tracked device, without lighting or line of sight limitations experienced by camera and other optical systems. As the position of the RF-transmitting tracked device is registered within a virtual environment produced by an interactive software program in communication with (or part of) the base station, the virtual viewpoint of the tracked device is controlled to reflect the relative position and orientation of the tracked device with respect to the virtual environment produced by the software program and displayed on a view screen.

  • Patent number: 10444323
    Abstract: Systems and methods for position tracking include at least three spatially separated radio-frequency (RF) sources of radio signals. Each RF source is disposed in an area at a location known to that RF source. Each RF source includes an RF transmitter configured to transmit radio signals that carry a unique identifier and the known location of that RF source. The position tracking system and method include at least one tag. Each tag is coupled to a different mobile object and includes a radio module with an RF receiver for receiving the radio signals transmitted by the at least three spatially separated RF sources. Each tag further includes memory and a processor that executes executable code stored in the memory to compute a range from that tag to each of the at least three RF sources and to compute a position of that tag based on at least three computed ranges.
