  • Patent number: 9646192
    Abstract: A method, device and system for generating an enrollment template are provided. The enrollment template is generated by collecting a placement image representing a portion of a biometric object such as a fingerprint. The placement image is localized on the fingerprint by comparing the data in the placement image to data in a floor map representing a larger image of the fingerprint obtained by swiping or rolling the fingerprint over a sensing area of a partial placement sensor. As additional placement images are obtained more information is provided for the enrollment template. The additional placement images are also localized to one another utilizing the floor map. The enrollment template is generated based on a grouping of each placement image to its neighboring placement images.

  • Patent number: 9594940
    Abstract: A method and device for compressing a fingerprint template is provided. The fingerprint template is derived from fingerprint image data captured from a sensor. The compressing process initially surveys the fingerprint template to determine one or more starting points for encoding. Subsequently, the compression process selects a starting point from the one or more starting points and proceeds to encode that starting point. After encoding the starting point, the compression process encodes all contours extending from the selected starting point. The above process is repeated until all starting points and their associated contours have been encoded.

  • Patent number: 8997018
    Abstract: A method for presenting a menu. A first menu level of a hierarchical menu structure is displayed in a one-dimensional list. A second menu level of the hierarchical menu structure is displayed in the one-dimensional list, wherein the second menu level is dependent on a selectable item of the first menu level and wherein items of the first menu level are contiguous and items of the second menu level are contiguous.

  • Patent number: 8175389
    Abstract: Recognizing handwritten words at an electronic device. A plurality of strokes is received at a common input region of an electronic device. The plurality of strokes in combination defines a word comprising a plurality of symbols, a relative geometry of a first subset of the plurality of strokes defines a first symbol and a relative geometry of a second subset of the plurality of strokes defines a second symbol such that the relative geometry of the first subset of the plurality of strokes is not related to the relative geometry of the second subset of the plurality of strokes, and at least one stroke of the first subset of the plurality of strokes is spatially superimposed over at least one stroke of the second subset of the plurality of strokes.

  • Publication number: 20080008387
    Abstract: A method and apparatus for recognition of handwritten symbols. A plurality of strokes is received at a common input region of an electronic device, wherein the plurality of strokes in combination defines a plurality of symbols. Sequential combinations of the plurality of strokes are analyzed with a plurality of symbol recognition engines to determine at least one possible symbol of the plurality of symbols defined by the plurality of strokes, wherein at least one of the plurality of symbol recognition engines is configured to identify symbols comprising a particular number of strokes.
