Abstract:
A carry/majority circuit, comprising a plurality of differential transistor pairs coupled in parallel and forming a pair of output nodes, with a single parallel gated level. Current is steered through a leg of the transistor pair having a higher input voltage.
Abstract:
A system and methods are provided for processing graphics to be displayed in a portable device. A current mode of operation of the portable device is identified. In a normal mode of operation, image data associated with the portable device is rendered by a graphics system of the portable device and stored in memory external to the graphics system prior to display. When a screen refresh mode of operation is identified, image data rendered by the graphics system is compressed and stored in memory integrated internal to the graphics system. The present disclosure has the advantage of allowing the memory external to the graphics system to be disabled during the screen refresh mode of operation, reducing power consumed by the portable device.
Abstract:
The invention is a provider agent product and method that operates as a software interface between a telephony card and a session manager in an advanced communications network. The provider agent receives event messages from the telephony card indicating on-hook events, off-hook events, and digit events. The provider agent instructs the telephony card to provide dial tone, ring current, ringback, and busy signals to the telephones. The provider agent also exchanges messages with a session manager in the network. These messages include: invite messages, reply messages, join messages, and terminate messages. In response to the above processing, the provider agent instructs the telephony card to interwork telephony signals on a telephony channel with ATM signals on an ATM virtual channel. The provider agent is comprised of a plurality of software objects that are stored on a software storage medium and that include: a controller object, port objects, and event objects. The provider agent objects are executed by a multithreaded processing system and each object has a separate processing thread. The provider agent and the telephony card communicate through an application programming interface that is specified in an Interface Definition Language (IDL) of a Common Object Request Broker Architecture (CORBA).
Abstract:
A mobile seat arrangement is provided which is configured to collapse for ease of storage and transportation. An x-brace, a rear lock brace and a front racking brace help to hold the mobile seat arrangement in an upright position for use as a stroller, wheelchair, or other seating arrangement. The braces also facilitate the collapse of the mobile seat arrangement in a compact fashion. Placement hooks are also provided to place a seat and back portion into the frame of the mobile seat arrangement. The mobile seat arrangement can also be tilted, with the angle between the seat and back of the seat and back portion remaining constant as the frame is tilted for the user. Arm rests and foot rests are also included.

Abstract:
A portable device is provided. The portable device includes a first graphics controller to generate a first rendered graphics data to be displayed on an integrated display, the first graphics controller including a first output coupled to the integrated display. The portable device further includes a second graphics controller to generate a second rendered graphics data and a display interface to format the second rendered graphics data for output to a first remote display, where the display interface includes a first input coupled to an output of the second graphics controller.
Abstract:
The present invention provides a method and system for detecting guideway anomalies. In particular, the present invention generates and couples a wave pulse into a guideway. The wave pulse travels down the guideway until it reaches an anomaly. The anomaly causes a return wave pulse. The time difference between the generated wave and the return wave allows calculation of the deference to the anomaly.
Abstract:
A multiple use level having an elongated body having two flange-like legs which extend at a right angle from one another from the corner apex. An L-shaped bracket is rotatably attached to one of the legs such that it may be freely rotated to any desired angle, then locked in position. The bracket includes a bull's-eye level on a first face thereof and a center line vial level attached to a rotating dial on a second face. A sighting laser may be detachably mounted on the L-shaped bracket. The level may be attached to a pipe or other member using magnets disposed in the body thereof or with an attachment cord. A flange bracket may be removable attached to one leg allowing pipe flanges to be oriented, alternatively the flange bracket may be integrated into the leg. Methods and processes for positioning construction members are also disclosed.
