Abstract: An optical force sensor that may compensate for environmental effects, including, for example, variations in temperature of the device or the surroundings. In some examples, two force-sensitive layers are separated by a compliant layer. The relative electrical response of the two force-sensitive layers may be used to compute an estimate of the force of a touch that reduces the effect of variations in temperature. In some examples, piezoelectric films having anisotropic strain properties are used to reduce the effects of temperature.

Abstract: A method, a system, and a computer-implemented method for performing multi-level deduplication of data are disclosed. A zone stamp is generated for each zone in a plurality of zones contained in at least one data stream. The zone stamp is compared to another zone stamp. The zone stamp and another zone stamp represent zones in the plurality of zones. The comparison is performed for zones at corresponding zone levels based on a determination that a zone stamp of a zone of a preceding zone level is not similar to another zone stamp of another preceding zone level. The zone at the preceding zone level includes at least one zone of a next zone level having a size smaller than or equal to a size of the zone of the preceding zone level. The zone and another zone are deduplicated based on a determination that the zone stamp is similar to another zone stamp.

Abstract: An optical force sensor, which may be used as input to an electronic device.

Abstract: A system, a method, and a computer program product for performing deduplication of data using a scalable deduplication grid are disclosed. A listing of a plurality of zone stamps is generated, where each zone stamp represents a zone in the plurality of zones in a data stream.

A first zone stamp in the listing is compared to a second zone stamp in the listing. The first and second zones are delta-compressed based on a determination that the first zone stamp is substantially similar to the second zone stamp. A server is selected to perform the comparison and delta-compression.

Abstract: Structures and methods are disclosed for an electronic device having an input surface that uses dual sensors to measure forces applied to the input surface. The forces can be estimated over a greater range of values than would be possible with either sensor alone. A second sensor can be used after a first sensor has reached a limit. A first sensor can be a strain sensor and a second sensor a pressure sensor. Both sensors may be resistance based, with signals from both sensors can be combined and measured by processing circuitry. Each sensor type may be part of planar arrays disposed beneath the input surface.
