  • Patent number: 10331166
    Abstract: A system includes first and second handheld devices. The first device transmits an acoustic signal, and the acoustic signal is reflected from an input object. The second device receives a received signal derived from a reflection of the acoustic signal from the input object. The second device determines information about the location or motion of the input object based on the received signal, and thereby detects a gesture performed by the input object.

  • Patent number: 10318044
    Abstract: An electronic device that can be operated with one hand more easily is provided. An electronic device 1 includes a touch sensor on each of the front surface and the back surface. A controller 14 changes the position of an object displayed in an upper part of a display 11 to a lower part of the display 11, upon detecting an operation on a back surface touch sensor 13. The controller 14 causes the display 11 to display an object not being displayed, upon detecting an operation on the back surface touch sensor 13.

  • Patent number: 10318038
    Abstract: An apparatus for combined capacitance and pressure sensing is described. The apparatus includes a multiplexer (75) having a plurality of inputs (76) and an output (F), a touch panel (29), and a front end module (3). The touch panel includes a layer structure (5; FIG. 15) comprising one or more layers, each extending perpendicularly to a thickness direction, the one or more layers including a layer of piezoelectric material (10; FIG. 15), the layer structure having first (6) and second (7; FIG. 15) opposite faces, and the layer(s) arranged between the first and second faces such that the thickness direction of each layer is perpendicular to the first and second faces. The touch panel also includes a plurality of first electrodes (8) disposed on the first face, each first electrode connected to a respective input of the multiplexer. The touch panel also includes at least one second electrode (9) disposed on the second face.

  • Patent number: 10269997
    Abstract: A method of creating a touch sensitive surface comprising detecting a voltage change in a light sensitive voltage generating device from among an array of light sensitive voltage generating devices that comprise a touch sensitive surface, in response to a lack of energy within a non-visible light spectrum reaching the light sensitive voltage generating device when a user contacts the touch sensitive surface, generating one or more location coordinates corresponding to a location in the array at which the voltage change occurred, and transmitting the one or more location coordinates to a processor configured to process a touch command received by the touch sensitive surface.

  • Patent number: 10269275
    Abstract: A method for inspecting a display panel in which pixels each including a drive transistor that passes a drive current when signal voltage is applied to the gate of the drive transistor, and a light-emitting element that emits light according to the flow of the drive current are arranged in rows and columns, includes: applying, across the gate and the source of the drive transistor, an initialization voltage less than or equal to the threshold voltage of the drive transistor; applying a power supply voltage to the drain of the drive transistor to which the initialization voltage is applied across the gate and the source; and determining, as a defective pixel with a current leak, a pixel having a light-emitting element that does not emit light when the power supply voltage is applied to the drain of the drive transistor and emits light after the elapse of a predetermined period.
