  • Publication number: 20230135200
    Abstract: A cantilever sensor (e.g., piezoelectric sensor) includes a beam with a sensor or electrode at a proximal end and a tip that extends from the sensor to the distal (unsupported) end of the beam. The tip is modified to modify (e.g., tune) the resonant frequency of the cantilever sensor. The resonant frequency of the cantilever sensor is tuned by using a material for the tip with a stiffness (e.g., a Young's Modulus) and/or a mass or density that results in the desired resonant frequency. The resonant frequency of the cantilever sensor can also be tuned by modifying the shape of the tip to have a higher vertical structure in a Z direction transverse to a length of the beam of the sensor.

  • Publication number: 20230136353
    Abstract: Clock generation circuit generating multiple divided signals satisfying respective desired offsets. A phase locked loop (PLL) is used to generate a PLL output having a frequency which is a desired multiple of that of a reference clock. The circuit divides the PLL output by a corresponding divisor to generate a corresponding divided signal, wherein each divided signal is offset from a common reference by at least an associated desired time offset. The common reference is timed with respect to the reference clock when the reference clock is available and with respect to a time reference signal otherwise. This arrangement is extended to use the internal time reference signal even for the cases where the reference clock is present by blocking the reference clock while the output systems across PLLs are aligned using the internal time reference signal to ensure desired offsets across different PLLs with a small uncertainty.

  • Publication number: 20230136347
    Abstract: A method for making a cantilever sensor includes forming a beam extending between a proximal portion and a distal end, and forming and attaching an electrode on the proximal portion. The beam is attached to a substrate in cantilever form so that the proximal portion of the beam is anchored to the substrate and the distal end of the beam is unsupported. The method includes modifying the resonance frequency of the cantilever sensor by forming at least the tip of the beam of a material having one or both of a density and Young's modulus that provides the desired resonant frequency, or by forming at least the tip of the beam so that it has a greater height in a Z direction transverse to a length of the beam than the proximal portion of the beam to thereby tune a resonant frequency of the sensor.

  • Patent number: 11640192
    Abstract: The present disclosure provides an apparatus and a method for implementing a USB-IF certified programmable power supply algorithm on a USB-C port. The method involves using a software code running on a microcontroller which monitors voltage and current being supplied by a power supply controller IC on a VBUS line of the USB-C port. Based on the detected voltage/current corrective actions are taken by the software code to bring the voltage/current to accepted levels as requested by a port partner. Further, a PPS accelerator is configured to compute an average or a new current/voltage value and provide the computed average or a new current/voltage value to a microcontroller for subsequent decision making and for other related assessment process.

  • Publication number: 20230128789
    Abstract: An integrated circuit (IC) includes input/output (I/O) ports, each operating using one of a pair of unequal power supplies during normal operation of the IC. A lower supply of the pair of unequal power supplies is required to be used as the power supply for the I/O port when a first input signal to the IC is received from an external source on a first I/O port of the I/O ports. The voltage range of the logic excursions of the first input signal is greater than the range from a magnitude of the lower supply to a constant reference potential. A regulation loop derives a derived lower supply having a magnitude equaling that of the lower supply from the higher supply of the pair of unequal power supplies, and applies the derived lower supply on a power supply node of the first I/O port.

The system separates the graphical user interface into interface portions and determines a correlation between the eye orientation and one or more portions to determine if any of the foregoing are viewed portions. The system determines whether a viewed portion contains a command input image and only allows user input commands via the command input image to be processed if the image is within a viewed portion.
