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 Global Navigation Satellite System (GNSS) receiver includes a Temperature Compensated Crystal Oscillator (TCCO) circuit. A micro jump of the TCCO circuit is detected by monitoring wide band phase values and carrier to noise ratio estimate values for each tracking channel of the tracking modules for the GNSS receiver. In response to a detected micro-jump, a frequency correction is calculated and applied to numerically controlled oscillators of phase/frequency lock loop circuits within tracking modules.

Abstract: Embodiments are directed to electrically confined ballistic devices, circuits, and networks. One such device includes a heterostructure that has a first semiconductor layer, a second semiconductor layer, and a two-dimensional electrode gas (2DEG) layer between the first and second semiconductor layers. The device further includes an input electrode electrically coupled to the 2DEG layer and an output electrode electrically coupled to the 2DEG layer. A first confinement electrode is positioned on the heterostructure. The first confinement electrode, in use, generates first space charge regions which at least partially define a boundary of the ballistic device within the 2DEG layer between the input electrode and the output electrode in response to a first voltage.

Abstract: Leadframes for semiconductor devices are manufactured by providing a laminar substrate of laser direct structuring material, the laminar substrate comprising first and second opposed surfaces, applying laser beam processing to the substrate to provide a first pattern of electrically-conductive formations at the first surface, a second pattern of electrically-conductive formations at the second surface and electrically-conductive vias through the substrate between the first surface and the second surface. Electrically-conductive material is formed, for instance via electrolytic or electroless growth of electrically-conductive material such a copper onto the first and second pattern of electrically-conductive formations as well as onto the electrically-conductive vias provided by applying laser beam processing to the substrate. The electrically-conductive vias are coupled to one or both of the electrically-conductive formations in the first pattern of electrically-conductive formations and the second pattern of electrically-conductive formations.

Abstract: A Multiple Accumulate (MAC) hardware accelerator includes a plurality of multipliers. The plurality of multipliers multiply a digit-serial input having a plurality of digits by a parallel input having a plurality of bits by sequentially multiplying individual digits of the digit-serial input by the plurality of bits of the parallel input. A result is generated based on the multiplication of the digit-serial input by the parallel input. An accelerator framework may include multiple MAC hardware accelerators, and may be used to implement a convolutional neural network. The MAC hardware accelerators may multiple an input weight by an input feature by sequentially multiplying individual digits of the input weight by the input feature.

Abstract: A method of forming a photonic device includes forming a cavity extending from a first major surface of a semiconductor wafer, performing a laser grooving process to form a first groove and a second groove, dicing the semiconductor wafer along the first groove and the second groove, and attaching an optical interposer to the bottom surface of the cavity. The cavity includes a first sidewall, an opposite second sidewall, and a bottom surface. The first groove is separated from the second groove by the cavity. The dicing passes through the cavity along a line connecting the first groove to the second groove.

Abstract: An integrated electronic device includes a semiconductor body and a passivation structure including a frontal dielectric layer bounded by a frontal surface. A conductive region forms a via region, extending into a hole through the frontal dielectric layer. An overlaid redistribution region extends over the frontal surface. A barrier structure includes at least a first barrier region extending into the hole and surrounding the via region. The first barrier region extends over the frontal surface. A first coating layer covers the top and the sides of the redistribution region and a second coating layer covers the first coating layer. A cavity extends between the redistribution region and the frontal surface and is bounded on one side by the first coating layer and on the other by the barrier structure.

Abstract: A differential current conveyor circuit includes two or more single-ended current conveyor stages and a common bias stage. First and second switches are set between the control terminals of the transistors in the common bias stage and a respective one of a first and a second coupling line of the single ended stages can be switched between the following: a reset state of the circuit with the transistors in the common bias stage coupled to the first and second coupling lines with the single-ended stages set to a bias condition; and a sensing state of the circuit with the transistors in the common bias stage decoupled from the first and second coupling lines, with the single-ended stages in a high impedance state with the control terminals of the input transistors of the single ended stages capacitively coupled to the input terminal.

Abstract: A pressure sensor is for positioning within a structure. The pressure sensor may include a pressure sensor integrated circuit (IC) having a pressure sensor circuit responsive to bending, and a transceiver circuit coupled to the pressure sensor circuit. The pressure sensor may include a support body having a recess therein coupled to the pressure sensor IC so that the pressure sensor IC bends into the recess when the pressure sensor IC is subjected to external pressure.

Abstract: An energy-harvesting generator provides energy for storage in a capacitor. A sensing circuit senses a voltage across the capacitor and generates an activation signal as a function of the sensed voltage. The activation signal is switches from a first value to a second value when the sensed voltage reaches an upper threshold and switches from the second value to the first value when the sensed voltage reaches a lower threshold. A signal transmitter powered by stored energy in the capacitor responds to the activation signal being switched to the second value by activating and transmitting a transmission signal. The signal transmitter further responds to the activation signal being switched to the first value by discontinuing transmission of the transmission signal and deactivating. A duration of time elapsing between de-activation and activation of the transmitter is indicative of an amount of energy harvested by the energy-harvesting electric generator.
