Abstract: A photosensitive apparatus, such as scanner, includes a plurality of pixels, each pixel having associated therewith a set of photosensors, each photosensor filtered to record a primary color. The photosensors are exposed to light of each primary color separately, thereby deriving test signals. A cross-color correction factor for the pixel is derived from the test signals. The cross-color correction factor is used in processing signals output from the pixel when an image is being recorded, so as to isolate the effects of signal crosstalk between closely-spaced photosensors of different colors.

Abstract: Systems and method provide compensation for temperature induced peak wavelength shift of LEDs is color parameter measuring systems that use a model to reconstruct target color parameter values from the reflectance values measured when the target is illuminated by LEDs. Several models may be constructed, with each model being trained at a unique temperature, resulting in a set of models that span the temperature range of interest. In real-time, the LED based color parameter measuring system measures the temperature and interpolates between the models to estimate the appropriate model to use at the temperature of interest. The estimated model is then used to perform the color parameter value estimation.

Abstract: A user conducts a telephone conversation without speaking. It does this by moving the participant in the public situation to a quiet mode of communication (e.g., keyboard, buttons, touchscreen). All the other participants are allowed to continue using their usual audible technology (e.g., telephones) over the existing telecommunications infrastructure. The quiet user interface transforms the user's silent input selections into equivalent audible signals that may be directly transmitted to the other parties in the conversation.

Abstract: A method is provided for aligning images on media produced by one or more print engines in an integrated print system. The method includes printing a first pattern of first symbols on a first region of a print medium with a first print engine and printing a second pattern of second symbols on a second region of the print medium with at least a second print engine in a manner to superpose the second pattern on the first pattern.
