Abstract: A force sensing touch screen input device is a solid assembly of multiple layers including a display with a touch-sensitive external surface, a first and second electrode layers separated by a compressible dielectric structure—forming a capacitive force-sensing array, and a rigid planar substrate. One or both electrode layers may be formed by metallizing a polymer surface of the rigid substrate or by creating a conductive electrode onto an internal surface of the display. To increase reliability, each layer is permanently adhered to or formed onto an adjacent layer over its entire surface, whereby preventing internal shifts therebetween. To increase response time, the cover glass flexibility, compressible dielectric structure and the gasket structure between the cover glass and the rigid planar substrates are selected to provide elastic compression and recovery during normal operating conditions.

Abstract: Encoding data includes: encoding a first portion of an array of data to generate a first set of coefficients, using a first transform; decoding the first set of coefficients to generate a decoded approximation of the first portion, using the first transform; selecting a second transform from multiple candidate transforms based at least in part on a measure of encoding performance for each candidate transform used to encode the decoded approximation of the first portion; and encoding a second portion of the array of data in proximity to the first portion of the array of data to generate a second set of coefficients using the selected second transform.

Abstract: A capacitive tactile sensor for measuring location and force of touch from an external object includes a drive electrode layer separated from a sense electrode layer by a dielectric substrate, which may be a two-sided FPCB. A first deformable conductive shield layer is further provided and is separated from either the drive electrode layer or the sense electrode layer by a first compressible dielectric layer. A control electronics are operatively connected to all of the drive electrode layer, sense electrode layer, and the first conductive shield layer. The control electronics may be configured to measure a change in capacitance upon the external object imparting local mechanical compression onto the first conductive shield layer and the first compressible dielectric layer. The tactile sensor improves reliability of interconnections between drive and sense electrodes and the control electronics.

Abstract: Encoding data includes: determining multiple patterns for computing one-dimensional transforms over a first array of data elements. Each pattern includes multiple subsets of data elements of the first array. Each subset included in a first pattern has substantially the same number of data elements as each of the other subsets included in the first pattern. Each data element of the first array is included in a single one of the subsets included in the first pattern. At least one subset included in the first pattern consists of data elements that are not in a contiguous sequence along a single dimension. Encoding the data includes: computing, for each pattern, multiple one-dimensional transforms over data elements of respective subsets included in the pattern; selecting a set of transform coefficients from a group of multiple sets of transform coefficients; and encoding the selected set of transform coefficients to represent the first array.

A representation of the scene is generated that includes an array of elements, where each of at least some of the elements corresponds to a determined portion of at least one of the images. An element of the array is based on a correspondence between a distance associated with a determined portion of at least one image and a focused distance associated with at least one image. The generated representation is stored or provided as output.

Abstract: A novel capacitive proximity tactile sensor is formed by an electrode layer and a compressible non-conductive layer. Positioning a conductive object in contact with the sensor and applying contact force onto the sensor surface allows for both detecting the location of touch (as in traditional proximity sensors) as well as measuring contact force (as in tactile array sensors) due to a capacitance-measuring sensor formed between the electrode layer and the object with the compressible non-conductive layer therebetween. Useful applications of the sensor include input device for consumer electronic item, flexible and thin weight scale, shoe insole for monitoring pressure distribution of a foot while walking, pressure-monitoring seat cushion and others.
