摘要： An apparatus for processing signals received from an acoustic touch surface comprises an analog input receiving an analog input signal having a signal level. The analog input signal comprises data indicative of a touch location on a touch surface. A plurality of gain elements receive the analog input signal and output gain-adjusted analog signals. A gain selection module selects one of the gain-adjusted analog signals based on the signal level of the analog input signal.

摘要： A color correction filtering system filters color video data by compensating for non-linearities and color characteristics specific to a color monitor. Color video data is received by the system, for example through a web browser, and in an accelerated manner passed through a pre-calculated gamut-shifting array. The color correction filtering system gamma decompensates incoming color video data referenced to a non-linear color space through use of a linearization filter. The gamut-shifting array may contain pre-calculated compensation values stored in a plurality of look-up tables. A non-linearization filter is applied to the gamut-shifted color video data to produce color video data compensated for non-linearities specific to the color monitor.

摘要： Resistive touchscreen system has a substrate with a first conductive coating having a first resistance and a coversheet with a second conductive coating having a second resistance. The substrate and coversheet are positioned proximate each other such that the first conductive coating faces the second conductive coating. The substrate and coversheet are electrically disconnected with respect to each other in the absence of a touch. First and second sets of electrodes for establishing voltage gradients in first and second directions are formed on the substrate and the coversheet, respectively. A controller biases the first and second sets of electrodes in two different cycles. The controller senses a bias current associated with at least one of the first and second resistances. The bias current has a reference value associated with no touch. An increase in the bias current relative to the reference value indicates two simultaneous touches.

摘要： A method of detecting a touch event on an acoustic fingerprint based touch system comprises digitizing at least two signals to form first and second sets of digitized signals. The at least two signals are received from at least two sensors on a touch panel. A frequency transform is performed upon the first and second sets of digitized signals to form first and second frequency transform data sets of frequency components. At least first and second live fingerprints are constructed wherein at least one of the first and second live fingerprints is based on the first and second frequency transform data sets. A touch location is identified based on the at least first and second live fingerprints.

摘要： A method for controlling printer color is provided. The method includes receiving cartridge color density data, such as from analysis of a test patch printed by the cartridge, and reference cartridge data, such as from analysis of a test patch printed and measured in accordance with a color standard. The color density data of the cartridge test patch is then mapped to the color density data of the reference cartridge test patch to generate mapped color density data, such as a look-up table that provides a dot activation for the cartridge that generates the same color density for a known dot activation for the reference cartridge. The mapped color density data is then used to control color density for printing a set of image data.
