Abstract: An opto-electronic video compression system is disclosed including a lens element for transmitting light of an image and having one or more lenses, each lens having a predetermined focal length. A sensor array includes a first sensor for receiving focused light from the lens element and a second sensor for receiving defocused light from the lens element, wherein the first sensor includes X×Y pixels and samples the focused light at each of the X×Y pixels, and the second sensor includes X/2×Y/2 pixels and samples the defocused light at each of the X/2×Y/2 pixels. An electronic differencing element in communication with the first and second sensor is also included for differencing the coefficients of co-located pixels.

Abstract: A prescription reminder system and method provides patients with paging devices, and uses a database of information about the patients and their prescriptions to generate reminder signals, based on which paging signals are transmitted to the paging devices, causing the paging devices to display reminder messages instructing each patient that it is time to take a dose of a prescribed medication.
