  • Publication number: 20160258992
    Abstract: Wideband capacitive sensing (single-ended or differential) is based on a modulated sense (capacitance) signal. A carrier/drive signal path modulates a reference signal with a carrier signal (such as fixed frequency or spread spectrum) to generate a carrier/drive signal, driven (with optional pre-scaling) out through an output node (to sense capacitor(s)). A sense signal path receives at an input/summing node up-modulated sense capacitance signal(s), corresponding to measured capacitance up-modulated to the carrier frequency, and, after filtering (optional) and amplification, demodulates the up-modulated sense capacitance signal with the carrier signal, to generate a demodulated sense capacitance signal corresponding to measured capacitance, which can be converted to sensor data. Sense signal path amplification can use charge amplification (capacitor feedback), or transimpedance amplification (resistor feedback).

  • Patent number: 9405773
    Abstract: Using a processor, receiving, a query including a query image. A database is searched for a set of images similar to the query image, using a two-pass search. The results of the searching are then provided, the results including image members of the set of images similar to the query image. The first pass may be performed using a TF-IDF algorithm and the second pass ranks a predetermined number of results from the first pass by a best match algorithm or other type of algorithm. The type of second pass algorithm may be selectable by a user. If an end signal is not detected, a further two-pass search may be made based on a subsequent query having a subsequent query image. The subsequent query image may be one of the results of the previous two pass search. A subsequent query image may change from an image of a product of a first product category to an image of a product of a second product category.

  • Patent number: 7870127
    Abstract: A method and apparatus for calculating the surface distance between two geographical locations are described. According to one aspect of the present invention, values are stored in a square look-up table for determining the square of a value. Also, values are stored in a square of linear to surface distance look-up table for determining the surface distance of a linear value. Cartesian co-ordinates of the two geographic locations and the square look-up table are then used to calculate the square of the linear distance between the two geographical locations and the square of linear to surface distance look-up table is used to convert the calculated square of the linear distance to a surface distance.
