Patents by Inventor Bradley James Griffis

Bradley James Griffis 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).

  • Receive mode upon expiration of UART transmit start BIT delay
    Patent number: 9892080
    Abstract: Signaling to control transmit/receive mode transitions of a serial half-duplex transceiver coupled externally to an integrated circuit is provided by the integrated circuit separately from a host processor of the integrated circuit with which the transceiver communicates. This can avoid slow transceiver turn-around times that may be associated with host processor control of the mode transitions.
    Type: Grant
    Filed: December 14, 2015
    Date of Patent: February 13, 2018
    Assignee: Texas Instruments Incorporated

  • Method of providing timing information for interrupts
    Patent number: 9715468
    Abstract: It is desirable for interrupt handling routines to be aware of the interrupt latency—the time between a interrupt request is received and the time when the interrupt service routine begins executing. A method is shown wherein the latency is measured by a dedicated counter and is available to the interrupt service routine. Alternately, a threshold may be set indicating the maximum acceptable latency and the interrupt service routine is signaled when said maximum is reached.

  • Supervising and sequencing commonly driven power supplies with digital information
    Patent number: 7630841
    Abstract: Methods and apparatus for power monitoring with sequencing and supervision are disclosed. An example method disclosed herein includes supervising a first power rail and a second power rail, sequencing a first enable signal associated with the first power rail and a second enable signal associated with the second power rail, and determining whether the first power rail is enabled based on regulation information determined while supervising the first power rail.
