Patents by Inventor ROBERT MCKELLAR

ROBERT MCKELLAR 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: 12638351
    Abstract: Apparatuses that include a junction-isolated semiconductor strain gauge and methods for manufacturing a junction-isolated semiconductor strain gauge are disclosed. In a particular embodiment, an apparatus comprises a silicon chip that includes a silicon substrate and a semiconductor strain gauge. In this embodiment, the semiconductor strain gauge includes a plurality of resistors formed by locally doping the silicon substrate and biasing the silicon substrate such that the resistors of the plurality of resistors are junction-isolated. The silicon chip also includes a field shield layer to isolate an output signal of the semiconductor strain gauge from external electrical fields.
    Type: Grant
    Filed: September 29, 2021
    Date of Patent: May 26, 2026
    Assignee: SENSATA TECHNOLOGIES, INC.

  • Patent number: 10525780
    Abstract: A tire pressure monitoring device for a wheeled vehicle that is capable of detecting vehicle motion from the output of a pressure sensor. The device determines from the output signal an indication of the power of the signal, for example the variance of the signal, and detects if the vehicle is stationary or in motion depending on the determined indication of power. The device may determine that the vehicle is in motion if the determined indication of power exceeds a threshold value.
