Abstract: A system and method for operating a high dynamic range analog front-end receiver for long range LIDAR with a transimpedance amplifier (TIA) include a clipping circuit to prevent saturation of the TIA. The output of the clipping circuit is connected via a diode or transistor to the input of the TIA and regulated such that the input voltage of the TIA remains close to or is only slightly above the saturation threshold voltage of the TIA. The regulation of the input voltage of the TIA can be improved by connecting a limiting resistor in series with the diode or transistor. A second clipping circuit capable of dissipating higher input currents and thus higher voltages may be connected in parallel with the first clipping circuit. A resistive element may be placed between the first and second clipping circuits to further limit the input current to the TIA.

Abstract: Techniques for improving efficiency of a switched-capacitor voltage regulator are provided. In an example, a switched-capacitor voltage regulator can include a switched-capacitor network having multiple gain configurations, a clock configured to switch capacitors of the switched-capacitor network between a charge state and a discharge state to provide a scaled output voltage, and a controller configured to select a capacitor configuration associated with a gain of the multiple gain configurations to provide the scaled output voltage within a desired output voltage range while continuously switching the capacitor configuration, and to interrupt switching of the capacitor configuration to permit an output voltage of the switched-capacitor voltage regulator to fall below the scaled output voltage but to remain above a lower limit of the desired output voltage range to save power by reducing losses due to the switching.

Abstract: Embodiments of the present disclosure provide mechanisms for measuring currents flowing in one or more conductor wires. The mechanisms are based on using magnetic sensor pairs arranged within a housing with an opening for the wires, where each magnetic sensor pair can generate a pair of signals indicative of magnetic fields in two different directions. The outputs of the sensor pairs can be used to derive a measure of current(s) flowing through the one or more wires. The use of magnetic sensor pairs that can measure magnetic field in two different directions may enable simultaneous current measurement in multiple wires placed within the opening, improve accuracy of current measurements while relaxing requirements for precise control of the placement of the wire(s), reduce the impact of stray magnetic interference, and enable both AC and DC measurements.

Abstract: Aspects of the embodiments are directed to a time-of-flight imaging system and methods of using the same. The time-of-flight imaging system includes a light emitter comprising at least one one-dimensional array of laser diodes; a photosensitive element for receiving reflected light from an object; and a light deflection device configured to deflect light from the light emitter to the object. In embodiments, the time-of-flight imaging system includes a lens structure to deflect emitting light from the laser diodes at a predetermined angle towards a light steering device.

Abstract: Power isolators with multiple selectable feedback modes are described. The power isolators may transfer a power signal from a primary side to a second side. A feedback signal may be provided from the secondary side to the primary side to control generation of the power signal on the primary side. In this manner, the power signal provided to the secondary side may be maintained within desired levels. The feedback signal may be generated by feedback circuitry configurable to operate in different modes, such that the feedback signal may be of differing types depending on which feedback mode is implemented.

Abstract: Isolators having a back-to-back configuration for providing electrical isolation between two circuits are described, in which multiple isolators formed on a single, monolithic substrate are connected in series to achieve a higher amount of electrical isolation for a single substrate than for isolators formed on separate substrates connected in series. Discrete dielectric regions positioned between isolator components forming an isolator provide electrical isolation between the isolator components as well as between the isolators formed on the substrate. The back-to-back isolator may provide one or more communication channels for transfer of information and/or power between different circuits.

Abstract: An integrated ion-sensitive probe is provided. In an example, an ion-sensitive probe can include a semiconductor substrate and a first passive electrode attached to the semiconductor substrate. The first passive electrode can be configured to contact a solution and to provide a first electrical voltage as function of a concentration of an ion within the solution. In certain examples, a passive reference electrode can be co-located on the semiconductor substrate. In some examples, processing electronics can be integrated on the semiconductor substrate.

Abstract: Systems and methods for detecting, isolating, and diagnosing machine faults are discussed. An exemplary system includes a network of sensor nodes deployed at machines or machine components to sense information of machine characteristics, and to generate physical or statistical features using the sensed machine characteristics. A cloud-computing device, communicatively coupled to the sensor network, can provide cloud-based services including detecting a machine fault, diagnosing a fault type, or estimating time to machine failure. A user interface associated with a client device can alert a user of the detected fault, such that the user can take preventive actions to minimize machine downtime.
