Abstract: A failure diagnosis circuit includes a multiplexer and a controller. The multiplexer receives address signals, and selectively outputs one of the address signals to an addressable module in response to a selecting signal. The controller generates a first one of address signals and the selecting signal. A built-in self-test circuit generates the second address signal. The addressable module includes addressable components responsive to the address signal. The controller processes the output of the addressable module responsive to the address signal to make a failure diagnosis. The built-in self-test circuit performs signature analysis on the read out output of the addressable module.

Abstract: A scanning laser projector includes an optical module with a housing defined by a top surface, a bottom surface, and sidewalls extending between the top surface and bottom surface to define an interior compartment within the housing. A given one of the sidewalls has an exit window defined therein. A first light detector is positioned at an interior surface of the given one of the sidewalls about a periphery of the exit window. A second light detector positioned at the interior surface of the given one of the sidewalls about the periphery of the exit window and on a different side thereof than the first light detector.

Abstract: Disclosed herein is a control system for a projection system, including a first subtractor receiving an input drive signal and a feedback signal and generating a first difference signal therefrom, the feedback signal being indicative of position of a quasi static micromirror of the projection system. A type-2 compensator receives the first difference signal and generates therefrom a first output signal. A derivative based controller receives the feedback signal and generates therefrom a second output signal. A second subtractor receives the first and second output signals and generates a second difference signal therefrom. The second difference signal serves to control a mirror driver of the projection system. A higher order resonance equalization circuit receives a pre-output signal from an analog front end of the projection system that is indicative of position of the quasi static micromirror, and generates the feedback signal therefrom.

Abstract: A device has memory and processing circuitry coupled to the memory. The processing circuitry generates a resonant axis drive signal to drive a Micro Electro Mechanical System (MEMS) mirror system at a resonance frequency, and generates a linear axis drive signal to drive the MEMS mirror system at a linear frequency corresponding to a video frame rate. Generating the linear axis drive signal includes generating, using interpolation, a current set of shape values based on a stored set of shape values and an indication of the video frame rate. The linear axis drive signal is generated using the current set of shape values.
