Abstract: A method and apparatus are provided to capture images using a laser projection display (LPD). In a full color LPD camera, three lasers (red, blue, and green) are deployed to scan an image and receive reflected laser light therefrom. The reflected laser light may be analyzed and assembled into a picture. The LPD may also be used to display the picture, to operate as a viewfinder, to print the picture, to operate as a range finder, and the like.

Abstract: A method and apparatus are provided to controllably reduce power of a laser projection display (LPD) in response to detecting a variation in a viewing surface. During the operation of the LPD, a controller 142 monitors laser light being reflected from the viewing surface. Since the controller 142 'knows' the amount of power that the LPD is being instructed to deliver, it may compare the known power to the reflected laser light to determine if a foreign object may be in the path of the laser light, and therefore, affecting the magnitude of the laser light. The controller 142 responds to detecting such an event by reducing power to the lasers.

Abstract: A method and apparatus are provided to controllably compensate for distortions in an image produced by an LPD, where the distortion arises from the shape and/or angle of the viewing surface relative to the LPD. For example, the LPD can determine the angle of the viewing surface relative to the LPD and then adjust the horizontal and vertical scan mechanisms to return the image to its original configuration, such as rectangular.

Abstract: Systems and methods for saving power in a distributed RFID system are provided. One RFID reader includes a RFID radio, a data communication radio, and a controller. The controller is configured to compare a current list of RFID tags responding to a current interrogation signal and a previous list of RFID tags responding to a previous interrogation signal to determine if there has been a change in RFID tags responding to the interrogation signals. The controller is also configured to command the data communication radio to transmit a signal to an external computing device if there has been the change in RFID tags, the signal indicative of the change, or not transmit the signal if there has not been a change. An RFID system includes a central computing device, multiple RFID tags, and multiple RFID readers similar to the above RFID reader.
