    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: 9696860
    Abstract: The present disclosure provides a capacitive touch sensor for an electronic device. The touch sensor has a trace carrier having a sensing surface, a connecting surface, and a number of electrically conductive traces on the trace carrier. The traces form a sensing pattern on the sensing surface and pass from the sensing surface to the connecting surface. The sensor also includes a capacitive sensing circuit operable to electrically couple to the traces at the connecting surface of the trace carrier, and to sense a capacitance change. A touch position on the sensing surface is determined dependent upon the sensed capacitance change.

  • Patent number: 9645669
    Abstract: An electronic device includes a touch-sensitive surface. The electronic device includes one or more sensors to detect intensity of contacts with the touch-sensitive surface. The device detects a first touch input on the touch-sensitive surface, and, in response to detecting the first touch input on the touch-sensitive surface, determines a first intensity applied by the first touch input on the touch-sensitive surface. The device identifies a first intensity model identifier from a plurality of predefined intensity model identifiers, and, in accordance with the first intensity applied by the first touch input on the touch-sensitive surface and one or more thresholds associated with the first intensity model identifier, determines a first touch characterization parameter. Subsequent to determining the first touch characterization parameter, the device sends first touch information to the first software application.

  • Patent number: 9645021
    Abstract: A sheet pressure sensor includes a first fiber layer, a second fiber layer, and a third fiber layer provided between the first and second fiber layers. The third fiber layer has connecting yarns that electrically connect first conductive portions of the first fiber layer and the second conductive portion in the second fiber layer with a predetermined electric resistivity. The sheet pressure sensor further includes a measuring instrument for measuring electric resistance between at least one of the first conductive portions and the second conductive portion. The connecting yarns unstrain due to deformation of the first or second conductive portion which is generated by applied pressure, and then are short-circuited with one of them. The sheet pressure sensor can detect the pressure while keeping air ventilation characteristic by giving a pressure detection function to the fiber layers.

  • Patent number: 9588619
    Abstract: Touch sensitivity is enabled using a touch system that comprises a panel configured to conduct signals, e.g. by TIR, along detection lines across a touch surface. A signal processor operates in a sequence of repetitions to: generate data samples that represent detected signal energy on the actual detection lines; generate based on the data samples, an interpolated sinogram comprising interpolation samples that represent fictitious detection lines which have a desired location on the touch surface; and reconstruct a signal interaction pattern for the touch surface based on the interpolated sinogram. The signal processor implements an error correction to counteract the influence of a change in validity status for a data sample among the data samples, by identifying interpolation samples affected by the change in validity status, and by setting each identified interpolation sample to a value that maintains a relative signal transmission of the fictitious detection line from a former repetition.

  • Patent number: 9557915
    Abstract: A system that detects and transitions a configuration of a dynamic tactile interface coupled to a computing device incorporating a touchscreen. The dynamic tactile interface includes a tactile layer and a substrate, wherein the tactile layer defines a tactile surface, a deformable region, and a first region adjacent the deformable region and coupled to the substrate opposite the tactile surface. A variable volume fluidly coupled to a fluid channel and a displacement device that transitions the deformable region from a retracted setting into an expanded setting in response to actuation of an input actuator coupled to the displacement device. A sensor detects a change in a position of the input actuator. In response to the change in the position, the configuration of the deformable regions of the dynamic tactile interface is correlated to a rendered graphical user interface on the touchscreen.
