Abstract: A processing arrangement for a computer comprising: first processor means (1) for processing a first set of instructions; and second processor means (2) for processing a second set of instructions, the second set of instructions being a subset of the first set of instructions, wherein the second processor means (2) is arranged to receive control signals and to process instructions in dependence upon those control signals without reference to the first processor means.
Abstract: The present invention provides a transceiver circuit that includes a transmission amplifier coupled with an antenna input/output node. The transmission amplifier is configured to amplify communications to be transmitted from the transceiver circuit. The transceiver circuit further includes a receiver and a field effect transistor. The receiver includes a receiver input coupled with the antenna input/output node. The field effect transistor is coupled between the receiver input and an electrical reference. The field effect transistor is configured to provide an open circuit when communications are received at the receiver input and to provide a closed circuit when communications are not being received at the receiver input.
Abstract: A self-contained means to move a media or component, such as fiber (12) or other miniature object, such as a lens, into a desired position is given. The fiber (12) or component is moved in various dimensions to achieve the desired location and is locked into position after the move. An input electrical signal, such as a voltage or current controls movement. A thermal actuator comprises the micro-positioner (80) using semiconductor technology in one embodiment. In another embodiment, of the present invention, a thermal or electrostatic actuator uses mechanical gears to move the fiber. Another embodiment of the present invention is implemented using mechanical technology such as microelectromechanical system (MEMS) technology. Another embodiment of the present invention, utilizes piezoelectric materials to facilitate fiber movement.

Abstract: The invention relates to a system and method for presenting data such as CAD data and three-dimensional graphic design data. The presentation method includes a set of one or more pages upon which objects are arranged. The objects may be associated with models, images, text, or buttons. For example, an object may be a walkthrough object associated with a three-dimensional model. The method also includes a means for synchronizing data sets. For example, a two-dimensional floor plan may be synchronized with a three-dimensional walkthrough. Further, the system includes a means for determining collisions and climbing of an actor in a first person walkthrough object.

Abstract: A Class D amplifier device with reduced power consumption uses a passive RC network. The output of the RC network directly feeds a comparator resulting in increased efficiency. The RC network is configured to perform several functions, including the low pass filtering of the feedback signal to remove high frequency/high amplitude clock components and provides a DC path from its output to reduce duty cycle errors. Additionally, the input signal receives low pass filtering, creating a generally flat frequency response. Finally, the clock signal is filtered to generate a triangle wave of good linearity and appropriate amplitude.
