Abstract: An equipment management system including a controller and a server. The controller communicatively couples to one or more remote systems. At least one of the remote systems includes a heating, ventilation, and air conditioning (HVAC) system, a refrigeration system, or a building automation system. The controller receives telemetry data associated with the operation of the one or more remote systems and with individual components of the one or more remote systems. The controller communicates at least a portion of the received telemetry data to the server. The server determines one or more operational commands for the one or more remote systems. The one or more operational commands are determined based on the telemetry data communicated from the controller to the server. The server communicates the one or more operational commands to the controller. The controller communicates the one or more operational commands to the one or more remote systems.

Abstract: A system includes one or more systems, a controller and a server. The one or more systems including one or more heating, ventilation, and air conditioning (HVAC) systems, refrigeration systems, or building automation systems. The controller is communicatively coupled to the one or more systems. The server is communicatively coupled to the controller. The controller receives telemetry data associated with the operation of the one or more systems. The received telemetry data includes data associated with individual components of the one or more systems. The controller also determines a subset of the telemetry data that has changed by comparing the received telemetry data to previous telemetry data. The controller also communicates to the server only the subset of the telemetry data that has changed.

Abstract: An interactive display system including a wireless pointing device, and positioning circuitry capable of determining absolute and relative positions of the display at which the pointing device is aimed. The pointing device captures images displayed by the computer, using a rolling shutter, the images including one or more human-imperceptible positioning targets. The positioning targets are presented as patterned modulation of the intensity (e.g., variation in pixel intensity) in a display frame of the visual payload, followed by the opposite modulation in a successive frame. At least two captured image frames are subtracted from one another to recover the positioning target in the captured visual data and to remove the displayed image payload. The capturing of images at the pointing device is synchronized with the release of image data to the display, to avoid errors in the positioning operation.
