  • Force sensitive touch panel devices
    Patent number: 10831292
    Abstract: An example force sensitive touch panel device can include a device body; a touch surface for receiving a touch force; a sensor for sensing touch force that is arranged between the device body and the touch surface; and a membrane configured to mechanically isolate the device body and the touch surface. Additionally, the membrane can apply a preload force to the sensor.

  • INTERFACE DEVICE AND METHODS OF USING SAME
    Publication number: 20110254777
    Abstract: An interface device for measuring a force applied by a user is disclosed. In one aspect, the interface device has a deformable body positioned on a support housing. In another aspect, the deformable body contains a fluid medium. The interface device also has at least one pressure sensor in fluid communication with the fluid medium. In an additional aspect, the interface device has processing circuitry for receiving pressure signals from the pressure sensors and producing an output signal corresponding to the force applied by the user.
