Abstract: The present disclosure is directed to a package, such as a wafer level chip scale package (WLCSP), with a die coupled to a central portion of a transparent substrate. The transparent substrate includes a central portion having and a peripheral portion surrounding the central portion. The package includes a conductive layer coupled to a contact of the die within the package that extends from the transparent substrate to an active surface of the package. The active surface is utilized to mount the package within an electronic device or to a printed circuit board (PCB) accordingly. The package includes a first insulating layer separating the die from the conductive layer, and a second insulating layer on the conductive layer.

Abstract: A circuit includes two thyristors coupled in anti-series. An AC capacitor has first and second electrodes respectively coupled to two different electrodes of the two thyristors. The first and second electrodes are coupled to receive an AC voltage. A control circuit detects discontinuance of application of the AC voltage to the AC capacitor and in response thereto simultaneously applies same gate currents to the two thyristors. A current path through the two thyristors (one passing current in forward mode and the other in reverse mode) discharges a residual voltage stored on the AC capacitor.

Abstract: A light projection system includes a GPU that receives video data containing video images, defines a two-dimensional grid (each element of which represents a position of a light beam at a different time), designates which elements of the two-dimensional grid correspond to positions of the light beam in a designated area, designates which elements correspond to positions of the light beam outside of the designated area with some positions outside being designated as calibration positions, maps each element corresponding to positions in the designated area to a corresponding pixel of a frame of a video image, and maps elements corresponding to calibration positions to calibration pixels. An ASIC receives the mapped pixels and mapped calibration pixels from the GPU, and generates a beam position control signal therefrom. A controller controls a movable mirror based on the beam position control signal.

Abstract: A projector includes a first laser source projecting a first laser beam, a second laser source projecting a second laser beam at an angle with respect to the first laser beam, and a mirror reflecting the first and second laser beams. Circuitry controls the mirror to simultaneously reflect the first and second laser beams in a first scan pattern to form a first image having a number of scan lines greater than two times a horizontal resonance frequency of the mirror divided by a desired frame rate of the first image. The first laser beam forms a first angle of incidence with the mirror and the second laser beam forms a second angle of incidence with the mirror, the second angle of incidence being equal to the first angle of incidence summed with the angle of the second laser beam with respect to the first laser beam.

Abstract: A fan-out wafer level package includes a semiconductor die with a redistribution layer on a sidewall of the semiconductor die. A redistribution layer positioned over the die includes an extended portion that extends along the sidewall. The semiconductor die is encapsulated in a molding compound layer. The molding compound layer is positioned between the extended portion of the redistribution layer and the sidewall of the semiconductor die. Solder contacts, for electrically connecting the semiconductor device to an electronic circuit board, are positioned on the redistribution layer. The solder contacts and the sidewall of the redistribution layer can provide electrical contact on two different locations. Accordingly, the package can be used to improve interconnectivity by providing vertical and horizontal connections.

Abstract: Disclosed herein is a laser projection system including a laser projector emitting a laser beam, a movable mirror apparatus reflecting the laser beam toward a surface, and a graphics processing unit (GPU). The GPU is configured to receive video data, estimate a varying speed of movement of the movable mirror apparatus for different positions of the laser beam across the surface, and process the video data based upon the estimated varying speed of movement. An application specific integrated circuit (ASIC) receives the processed video data, and to generate a beam position control signal based upon required or desired movement of the movable mirror apparatus. A laser driver controls the laser projector as a function of the processed video data, and a mirror controller controls the movable mirror apparatus as a function of the beam position control signal.

Abstract: Disclosed herein is a mirror controller for an oscillating mirror. The mirror controller includes a processor configured to receive a mirror sense signal from the oscillating mirror and to determine a phase error between the mirror sense signal and a mirror drive signal. The processor determines the phase error by sampling the mirror sense signal at a first time, sampling the mirror sense signal at a second time at which the mirror sense signal is expected to be equal to the mirror sense signal as sampled at the first time, and generating the phase error as a function of a difference between the sample of the mirror sense signal at the second time and the sample of the mirror sense signal at the first time.
