  • Patent number: 10949024
    Abstract: A pulse of terahertz radiation is transmitted through a touch panel formed of a dielectric material. The pulse generates an employable evanescent field in a region adjacent to a touch surface of the touch panel. The terahertz radiation has a frequency range between 0.1 terahertz and 10 terahertz. A reflected pulse is generated from an object located within the region adjacent to the touch surface of the touch panel. A position is triangulated of the object on the touch surface of the touch panel, based at least in part on the reflected pulse.

  • Patent number: 10823581
    Abstract: A sensor power management arrangement includes a signal processing circuit configured to receive signal from a sensor, to test the signal against at least one criterion, and to pass the signal for further processing in response to the signal passing the at least one criterion. In this way, only signals that are of a sufficient importance or significance will consume the maximum amount of processing energy and through processing by later processes or circuitry. Should a signal from a sensor not be strong enough or meet other criteria, power will not be wasted in preparing that signal for provision to the microcontroller or microprocessor. Additional flexibility in the sensor power management can be realized by adjusting the criteria against which the sensor signal is compared based on a status of the sensor apparatus.

  • Publication number: 20180219533
    Abstract: In the described examples, a driver includes a signal controller that provides a gate control signal to a gate buffer coupled to a gate of a transistor and a field plate control signal to a field plate buffer coupled to a field plate of the transistor. The signal controller provides a rising edge on the field plate control signal causing the field plate buffer to provide a bias voltage on the field plate of the transistor a predetermined amount of time after providing a rising edge on the gate control signal that causes the gate buffer to provide a turn-on voltage on the gate of the transistor that causes the transistor to transition from a cutoff region to a saturation region and to a linear region.

  • Patent number: 9484630
    Abstract: In some developing interconnect technologies, such as chip-to-chip optical interconnect or metal waveguide interconnects, misalignment can be a serious issue. Here, however, a interconnect that uses an on-chip directional antenna (which operates in the sub-millimeter range) to form a radio frequency (RF) interconnect through a dielectric waveguide is provided. This system allows for misalignment while providing the increased communication bandwidth.

  • Patent number: 9163941
    Abstract: Accelerometers have a number of wide-ranging uses, and it is desirable to both increase their accuracy while decreasing size. Here, millimeter or sub-millimeter wavelength accelerometers are provided which has the advantage of having the high accuracy of an optical accelerometer, while being compact. Additionally, because millimeter or sub-millimeter wavelength signals are employed, cumbersome and awkward on-chip optical devices and bulky optical mediums can be avoided.

  • Patent number: 9013339
    Abstract: To date, bandwidth mismatch within time-interleaved (TI) analog-to-digital converters (ADCs) has been largely ignored because compensation for bandwidth mismatch is performed by digital post-processing, namely finite impulse response filters. However, the lag from digital post-processing is prohibitive in high speed systems, indicating a need for blind mismatch compensation. Even with blind bandwidth mismatch estimation, though, adjustment of the filter characteristics of track-and-hold (T/H) circuits within the TI ADCs can be difficult. Here, a T/H circuit architecture is provided that uses variations of the gate voltage of a sampling switch (which varies the “on” resistance of the sampling switch) to change the bandwidth of the T/H circuits so as to precisely match the bandwidths.

  • Patent number: 8970411
    Abstract: Traditionally, pipelined continuous-time (CT) sigma-delta modulators (SDM) have been difficult to build due at least in part to the difficulties in calibrating the pipeline. Here, however, a pipelined CT SDM is provided that has an architecture that is conducing to being calibrated. Namely, the system includes a digital filter and other features that can be adjusted to account for input imbalance errors and well as quantization leakage noise.
