  • Force sensing architectures
    Patent number: 11803276
    Abstract: An electronic device with a force sensing device is disclosed. The electronic device comprises a user input surface defining an exterior surface of the electronic device, a first capacitive sensing element, and a second capacitive sensing element capacitively coupled to the first capacitive sensing element. The electronic device also comprises a first spacing layer between the first and second capacitive sensing elements, and a second spacing layer between the first and second capacitive sensing elements. The first and second spacing layers have different compositions. The electronic device also comprises sensing circuitry coupled to the first and second capacitive sensing elements configured to determine an amount of applied force on the user input surface. The first spacing layer is configured to collapse if the applied force is below a force threshold, and the second spacing layer is configured to collapse if the applied force is above the force threshold.

  • Telecommunications switch with integral feature installation capability
    Patent number: 5384823
    Abstract: The operating system control device in a telecommunications switch is capable of operating under the control of software instructions associated with a new switch feature for executing a series of actions used to integrate the new switch feature with the operating system. The operating system control device further provides the capability operating under the control of software instructions for testing the operability of the new switch feature. This minimizes the costs associated with the installation of new features and the amount of skilled craft personnel time required.
