  • Publication number: 20030030241
    Abstract: A cross-car suspension system with MacPherson strut replaces the lower control arms, coil springs, and anti-roll bar assembly in the prior art with a simple composite beam. By carefully designing the shape of the beam, the material system and the pivot locations, the ride and roll stiffness and camber and toe characteristics of the original prior art suspension system can be preserved while significantly reducing weight.

  • Patent number: 6481455
    Abstract: A bubble trap for an extracorporeal blood handling or other fluid handling system has a chamber (10) constructed from a top section (20) and bottom section (30). There is a fluid inlet (50), gas vent port (70) for purging gas that has separated from the fluid in the chamber, and a fluid outlet (50). There are two balls (64) and (74), which act as check valves to prevent fluid flowing out the vent port, and gas escaping through the fluid outlet. The chamber geometry prevents entrapment of either ball in the corner as blood level rises or falls. Squeeze bulbs (66) and (76), and shutoff valves (68) and (78), provide for unseating the check balls.

  • Publication number: 20020149190
    Abstract: The present invention provides for a fiber reinforced suspension member having an integral pivot opening. The suspension member includes a first portion, a second portion and a central portion disposed in between the first portion and the second portion. The suspension member in accordance with the teachings of the present invention is formed of fibers that extend longitudinally from the first portion to the central portion and curve around the central portion such that an opening is defined in the central portion. The fibers forming the suspension member typically comprise an upper fiber layer and a lower fiber layer. The upper fiber layer and the lower fiber layer interface in the first portion and the second portion and are separated in the central portion. The upper layer fiber and the lower layer fiber are reinforced around the opening by stitching reinforcing fibers through the thickness of the suspension member.

  • Patent number: 6108538
    Abstract: In cellular communication systems, hand-offs are performed to maintain links as subscriber units (110) and beams move relative to each other. The hand-off determination procedure (500) is performed in overlap regions (240, 340). Candidate beams are identified and hand-off types are determined based on the satellite (120) associated with the candidate beam. Thresholds are established and changed to optimize a hand-off request determination procedure (500). Two hand-off types are considered. An inter-satellite hand-off is requested (514) when the current beam and the candidate beam are on different satellites (120). An intra-satellite hand-off is requested (510) when the current beam and the candidate beam are on the same satellite (120). Thresholds are dynamically changed and algorithms are used to minimize the number of inter-satellite hand-offs.

  • Patent number: 5930512
    Abstract: Apparatus and computer implemented method for process modeling using both a web server and a workflow server in process definition. During buildtime, a process definition in the language of some workflow process modeler is fed to transform f(p), which provides a translate process definition into a hypertext markup language (HTML) representation of the workflow process. A user utilizing the facilities of an HTTP server may operate a web browser to request that HTTP server provide the HTML process definition to enable the user to create, or read and modify, the process definition as desired. The result is then fed through an inverse transform f'(p) to a workflow server in the language of that server, for invocation and execution during runtime of the programs defined during buildtime.

  • Patent number: 5764480
    Abstract: Disclosed is a media console of a personal computer system that includes a drive housing that can be moved within a base member between an open position and a closed position. A direct access storage device (e.g., floppy disk drive) is disposed within the drive housing and has an opening for receiving a removable storage medium. The open position is characterized in that the opening in the direct access storage device is accessible to a user while the closed position is characterized in that the opening in the direct access storage device is not accessible to the user.The drive housing pivots on pins which are disposed at opposite ends of a back portion of the drive housing. The pins fit within grooves which are located at each end of the base member. A spring coupled to the base member and the drive housing biases the drive housing toward the open position. A latch for latching the drive housing in the closed position is coupled to the base member and the drive housing.

  • Patent number: RE37757
    Abstract: A subscriber unit (26) communicates with a satellite communication system (10) that projects cells. The satellites (12) and cells move relative to the earth. During every other TDMA frame, a subscriber unit (26) measures the signal strength of all candidate hand-off beams. The signal strength of the current beam is compared to the signal strength of the candidate hand-off beams. When the signal strength of the current beam is not the strongest, a counter is incremented (108). A hand-off is requested to the beam with the greatest signal level when the counter exceeds a predetermined threshold. Accordingly, only after the current antenna beam has not been the strongest beam for a certain period of time, is a hand-off requested. A different counter threshold is used for candidate hand-off beams from other satellites (12).
