  • Patent number: 10198108
    Abstract: Detecting a signal from a touch and hover sensing device, in which the signal can be indicative of concurrent touch events and/or hover events, is disclosed. A touch event can indicate an object touching the device. A hover event can indicate an object hovering over the device. The touch and hover sensing device can ensure that a desired hover event is not masked by an incidental touch event, e.g., a hand holding the device, by compensating for the touch event in the detected signal that represents both events. Conversely, when both a hover event and a touch event are desired, the touch and hover sensing device can ensure that both events are detected by adjusting the device sensors and/or the detected signal. The touch and hover sensing device can also detect concurrent hover events by identifying multiple peaks in the detected signal, each peak corresponding to a position of a hovering object.

  • Patent number: 9608629
    Abstract: In the present invention, a capacitance-type switch is provided with an operation plate and an electrode plate. The operation plate forms operation surfaces operated by the touch of a fingertip F (operation body) of a user. The electrode plate is disposed on the side of the operation plate opposite the operation surfaces. Furthermore, the capacitance-type switch is turned on and off in response to the change in capacitance caused between the fingertip F and the electrode plate. In addition, a high-permittivity material is disposed in an outer circumferential section of the electrode plate, the high-permittivity material having a higher permittivity than the operation plate. It is possible to improve the sensitivity of the capacitance-type switch while minimizing malfunctioning.

  • Patent number: 9582078
    Abstract: Techniques are described to furnish a touchless joystick-type controller in a portable electronic device. The techniques may be implemented within an electronic device that comprises one or more sensors configured to detect a target at a distance from the sensor and provide a signal in response thereto. The signal is received in response to the sensor detecting a target within a field of view of the sensor. A position of the target relative to a point of reference is then determined based on the signal. Movement of the target may be tracked based on changes in the determined position relative to the point of reference. In embodiments, the target comprises a thumb or a finger of a hand of a user of the electronic device and the determined position to furnish a joystick-type control input.

  • Patent number: 9350344
    Abstract: A test pattern membrane test method uses a test pattern membrane to test the capacitive sensors of a device. The device is placed in the test fixture. The capacitive sensors are read without the test pattern membrane, storing as a set of baseline measurements. The test pattern membrane is placed on the unit to be tested. The test pattern membrane has a plurality of conductive areas on a non-conductive substrate. The conductive areas are arranged in a pattern that corresponds to the pattern of capacitive sensors. The sensors are read again to obtain a set of stimulated measurements. Differences for each of the sensors are determined between the sensor readings with and without the test pattern membrane in place. This difference is compared to a threshold. A sensor is considered to be functioning properly if the difference value is greater than the sensor's threshold value.
