  • Patent number: 10209834
    Abstract: A display with integrated self-capacitance sensors comprises a sensor electrode and a guard layer in the display stack. Touch displays combine internally elements required for the display function and the touch sensing function. In an embodiment, the common voltage layer, VCOM layer, is used as the guard layer and another layer on top of the common voltage layer, for example a color filter layer, is used as the electrode array layer. The functionality of the common voltage layer is alternated between the touch sensing function and the display function. Either function may be used while the other function is disabled.

  • 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: 10082913
    Abstract: Embroidered sensor assemblies are described that are formed on a flexible substrate, such as a suitable fabric material. Conductive patterns are embroidered into the flexible substrate to form an array of sensors that can be configured in various ways and used in many different applications. A sensor assembly can implement touch sensitive sensors arranged to recognize input by measuring capacitance. The sensor assembly can also implement pressure and/or force sensitive controls for an input device, such as a keyboard. Other types of sensing are also contemplated such as detection of proximity, motion, flow, gestures, and/or strain. A conductive pattern can be formed in a single layer of material and/or via a single continuous run of conductive material. The embroidered sensor assembly is flexible and therefore can be shaped to conform to various different kinds of objects and form “smart” surfaces for those objects.
