Patents by Inventor Federico Cattivelli

Federico Cattivelli has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10966161
    Abstract: In some aspects, the disclosure is directed to methods and systems for in-packet transmission power control. Measurement circuitry in communication with a transmission stage of a device is configured to generate a transmitted signal strength measurement signal based on an output of the transmission power amplifier during transmission of a packet. Measurement conversion circuitry connected to the measurement circuitry is configured to convert the transmitted signal strength measurement signal from the measurement circuitry to an output power measurement. Power control circuitry connected to the measurement conversion circuitry is configured to generate a power correction signal based on the output power measurement and an output power target value. Power ramping circuitry connected to the power control circuitry is configured to provide a gain signal to the transmission stage of the device based on the power correction signal.

  • Publication number: 20150227241
    Abstract: Systems and methods are provided that allow a touch sensor, such as a mutual capacitive touch panel, to switch from an operative transmit (TX) frequency at which the mutual capacitive touch panel is driven to an alternative TX frequency. When switching to an alternative TX frequency, an alternative baseline capacitance value corresponding to the alternative TX frequency may be utilized to determine whether a touch event has occurred on the mutual capacitive touch panel. Frame scans can be repeatedly performed at the operative TX frequency and the alternative TX frequency in rapid succession, and an average difference of the frame scans can be calculated and utilized to generate the alternative baseline capacitance value which may be insensitive to sudden ambient changes and moving touch events affecting the mutual touch capacitive panel.
