Abstract: The present invention is directed to a system and methodology in which the stepper motor (or a DC motor/encoder combination) of an optical scanning device is replaced by a DC motor which receives feedback information from an extended photodetector used in the scanner, or a proximately close second photodetector. The photodetector of current scanners may be extended (or a second photodetector may be incorporated) to read a margin marking located on, or attached to, the scanner body and the resolution of the extended portion, or separate photodetector, may be increased to accurately capture positioning information. The photodetector of the present invention detects the margin marking, typically located outside of the document scanning area, to determine positional information which is used by the processor to accurately determine position.

Abstract: A system is provided for connecting received calls, which may be voice or data calls having a common destination identifier associating the calls with a subscriber, to a selected at least one of one or more call options assigned to the subscriber. In one embodiment, the system includes a call detector, a voice call decoder, and a data call decoder. The call detector has an input for receiving the calls. It also has a first output and a second output. The detector provides a received call to the first output if it is a voice call and provides it to the second output if it is a data call. The voice call decoder has an input operably connected to the first output of the call detector for receiving the voice calls. It also has one or more outputs operably accessible to one or more voice call options for connecting the voice calls each to a selected at least one of the one or more voice call options.

Abstract: The present invention is directed to a system and a methodology for including software controlled filtering effects in digital cameras to reduce the need for physical filters. Filtering effects emulated by the software include technical filters, correction filters and effects filters. The invention includes an input system which allows the user to select various filtering effects, preview the filtered image and record the filtered image in a lossy compressed file format. The input system may consist of a hierarchical menu system, touch screens, voice activation, pointing devices or a round robin mechanism. In addition, the input system includes an ability for the user to indicate a selection has been made such as an enter key or a selection completion signal.
