Abstract: A finger sensing apparatus may include an integrated circuit (IC) substrate, an array of finger sensing elements on the IC substrate, and encryption circuitry on the IC substrate cooperating with the array of finger sensing elements for encrypting a user template comprising finger template data and at least one user credential. The at least one user credential may enable another device, such as a host platform, to perform at least one protected operation.

Abstract: This invention features both a device and method for reading machine readable code. The device includes a scanning apparatus, a signal processor and a data processor. The scanning apparatus scans the code and outputs a signal representative of at least a portion of the code. The signal processing means processes each of the signals outputted by the scanning means and further provides signal identification data, including a width and position associated with each of the signals, for each successive scan of the code. The data processing means reconstructs the code from the signal identification data for each successive scan of the code, provided by the signal processing means. The data processing means includes a position aligning means for both selecting an element in a previous scan and calculating the position of that element in a successive scan based upon a calculated offset, and means for aligning the successive scan with the previous scan by means of the calculated offset.

Abstract: This invention features a device and method for reading machine readable code, having a plurality of code elements, on an object. The device includes a scanning apparatus, a signal processor and a data processor. The scanning apparatus successively scans the code and outputs a signal representative of at least a portion of the code, for each successive scan of the code. The signal processor processes each of the signals outputted by the scanning apparatus and further provides signal identification data, including a width and position associated with each of the outputted signals, for each successive scan of the code. The data processor reconstructs the code from the signal identification data for each successive scan of the code, provided by the signal processor. The data processor reconstructs the code by both determining the position of a selected code element for a successive scan and by positionally aligning the selected code element with the corresponding element from a prior scan.
