    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.

  • Patent number: 10056205
    Abstract: An electronic device such as a cover for a portable device or other electronic equipment may have circuitry mounted in a housing. The housing may be formed from layers of material such as fabric and polymer layers. The fabric may be formed from woven polymer yarn. The fabric may be treated with chemicals to improve stain resistance and wear resistance, may be provided with a polymer backing layer, and may receive molded plastic structures. Patterned areas may be woven into the fabric, may be formed by placing coatings on selected portions of the fabric, or may be formed by embroidering or otherwise locally processing the fabric. The patterned areas may form labels for keyboard keys, logos, key trim patterns, and other features for an electronic device. Patterned areas may have locally enhanced light transmission characteristics and may be backlit.

  • Patent number: 10001894
    Abstract: A method of operating a contact sensor and a method of calibration of a contact sensor. The contact sensor comprises an array of discrete and spaced apart sensing elements (102, 202) connected to a resistive element (101, 201) with the location or size of a contact being detectable by measurement of one or more electrical parameter(s) relating to impedance steps along the resistive element (101, 201) is described. The method of operating involves determining a length of the sensing element between the contact and the resistive element and using this to compensate for a parasitic resistance present in the measured resistance of the resistive element.

  • Patent number: 9965092
    Abstract: A force-responsive sensor incorporating a force-sensitive element is in communication with a power controller. The power controller changes one or more performance characteristics associated with the force-responsive sensor. A performance characteristic can include a bias voltage or current, a duty cycle, a sampling rate, and so on. The performance characteristic(s) can be changed in response to a touch event or based on an operational setting of the force-responsive sensor (or an electronic device incorporating the force-responsive sensor). Regulation of the performance characteristic(s) reduces power consumption of the force-responsive sensor.
