Abstract: A light fixture can include at least one light fixture component. The light fixture can also include at least one sensor that measures at least one parameter associated with the at least one light fixture component. The light fixture can further include a prognostic and health monitoring (PHM) system coupled to the at least one sensor, where the PHM system analyzes at least one measurement, made by the at least one sensor, to identify at least one factor that affects longevity of the at least one light fixture component.

Abstract: A method of compensating for camera motion during capture of the image in a rolling shutter camera, the method comprising: receiving an image of a scene captured by a camera with a rolling shutter; extracting line segments in said image; estimating the movement of the camera during the capturing of the image from the received image; and producing an image compensated for the movement during capture of the image, wherein the scene is approximated by a horizontal plane and two vertical planes that intersect at a line at infinity and estimating the movement of the camera during the capture of the image comprises assuming that the extracted line segments are vertical and lie on the vertical planes.

Abstract: A light fixture can include at least one light source, and at least one power supply that receives primary power, where the at least one power source generates final power using the primary power, where the at least one power supply delivers the final power to the at least one light source. The light fixture can also include a controller coupled to the at least one power supply, where the controller detects an adverse event, and where the controller controls the at least one power supply to provide the final power to the at least one light source during the adverse event.
