Abstract: A glitch filter includes a storage element for storing a current state, which is the output of the filter. An output of the storage element is connected to one input of a state comparator. Another input of the state comparator is connected to an input signal. A programmable clock delay is connected between the state comparator and the storage element. The programmable clock delay may provide a programmed duration independent of the technology used for implementation. The glitch filter is arranged such that the input signal is stored as the new current state in the storage element only if the input signal changes and then remains unchanged for the programmed duration.

Abstract: The present description concerns a circuit for converting from a first alternating voltage to a second voltage. The circuit includes: a first thyristor; a first control circuit of the first thyristor; a power factor correction circuit comprising a coil; and a first circuit configured to convert a third voltage into a fourth DC voltage. The third voltage corresponds to a difference between a potential at a first node connected to an output node of the coil and a reference potential. The fourth DC voltage is configured to supply the first control circuit of the first thyristor, and is referenced with respect to the same reference potential as the third voltage.

Abstract: A method of operating a display includes performing a non-synchronized touch scan pattern on a display with a controller coupled to the display. The non-synchronized touch scan pattern schedules touch scans independent of a refresh rate of the display. Upon the controller detecting a first synchronization pulse from a display controller coupled to the controller and the display, a first pulse-checking timer is started. Upon detecting a second synchronization pulse from the display controller and before the first pulse-checking timer expires, a first display refresh rate for the display is obtained from an interval between the first synchronization pulse and the second synchronization pulse. A synchronized touch scan pattern is performed with the controller, and is scheduled to avoid touch scans coinciding with refreshes of the display performed at the first display refresh rate.

Abstract: A scanning laser projector includes an optical module and projection engine. The optical module includes a laser generator outputting a laser beam, and a movable mirror scanning the laser beam across an exit window defined through the housing in a scanning pattern wider than the exit window such that the laser beam is directed through the exit window in a projection pattern that is smaller than and within the scanning pattern. A first light detector is positioned about a periphery of the exit window such that as the movable mirror scans the laser beam in the scan pattern, at a point in the scan pattern where the laser beam is scanned across an interior of the housing and not through the exit window, the laser beam impinges upon the first light detector. The projection engine adjusts driving of the movable mirror based upon output from the first light detector.

Abstract: A semiconductor package includes a silicon substrate with an active surface and an inactive surface. A semiconductor device, such as an image, light, or optical sensor, is formed in the active surface and disposed on the substrate. A glass plate is coupled to the substrate with adhesive. The glass plate includes a sensor area that corresponds to the area of the semiconductor device and holes through the glass plate that are generally positioned around the sensor area of the glass plate. During formation of the package, the holes through the glass plate allow gas released by the adhesive to escape the package and prevent formation of a gas bubble.

Abstract: A light projection system includes a MEMS mirror operating on a mirror drive signal to generate a mirror sense signal resulting from operation of the MEMS mirror based on the mirror drive signal. A mirror driver generates the mirror drive signal from a drive control signal. A controller receives the mirror sense signal from the MEMS mirror, obtains a first sample of the mirror sense signal at a first phase thereof, obtains a second sample of the mirror sense signal at a second phase thereof, wherein the first and second phases are separated by a half period of the mirror drive signal, with the second phase occurring after the first phase, and generates the drive control signal based on a difference between the first and second samples to keep the mirror drive signal separated in phase from the mirror sense signal by a desired amount of phase separation.
