摘要： A handheld device includes an electronic display having an active area for presenting visual content and a bezel disposed around the electronic display. The bezel may have an opening allowing a person to view the active area. The handheld device also includes a force sensing system having a force sensing element that is disposed below an external surface of the bezel. The force sensing system may be configured to a sense a force on the bezel and to generate a sensor signal indicative of the force. The handheld device may further include a processor operable to receive the sensor signal and to execute a function based on the sensor signal.

摘要： A system includes a surface having a demarcated area and discrete areas disposed on the surface. The discrete areas may each be configured to receive user input. At least a portion of the discrete areas overlap the demarcated area. The system further includes a sensing layer disposed underneath the surface. The sensing layer may be configured to sense force applied to the surface in response to the user input.

摘要： Certain example embodiments include a press sensor element that includes a piezoelectric layer having a first surface in communication with a first layer, the first layer including a first conductive region, where the first conductive region covers at least a central portion the first surface. The sensor element includes a second surface in communication with a second layer, the second layer including a second conductive region, a third conductive region, and a first non-conductive void region separating the second conductive region and the third conductive region. An area of the first conductive region is configured in size relative to an area of the third conductive region to substantially reduce a thermally-induced voltage change between two or more of the first, second, and third conductive regions responsive to a corresponding temperature change of at least a portion of the piezoelectric layer.

摘要： A system includes a first force sensing transducer being configured to enable force sensing detection of a first force input on a first contact interface, a memory, and a processor that is operatively coupled to the memory and the first force sensing transducer. The processor is configured to perform operations including detect the first force input on the first contact interface via the first force sensing transducer, measure at least one of a magnitude or a direction of the first force input detected by the first force sensing transducer, compute a force sensing data parameter based on the measured at least one of the magnitude or the direction of the first force input; determine an output function based on the force sensing data parameter; and cause an activation of the output function.

摘要： A door handle includes a handle body with an external surface, an internal portion, and a mounting feature configured to couple the handle body to a door. The door handle also includes a force sensing element disposed in the internal portion of the handle body. The first force sensing element is configured to measure a force applied to the external surface of the door handle. The door handle further includes a communication element coupled to the force sensing element. The force measured by the force sensing element is used to determine an output function.
