  • Patent number: 6835426
    Abstract: Pulse-position synchronized deposition of a material in miniature structure manufacturing processes is carried out in a fabrication tool including a material carrier element, a source of energy generating pulses of energy, a substrate, and a control unit operatively coupled to the source of energy, substrate, and the material carrier element. The control unit exposes a first area of the material carrier element to a first pulse of energy, pauses the exposure while initiating relative motion between the source of energy and the substrate at a predetermined first speed and relative motion between the material carrier element and the energy source at a predetermined second speed which is a function of the first speed, and slowing (or stopping) relative motion between the energy source, material carrier element, and the substrate, while exposing the unablated area of the material carrier element adjacent to previously ablated area to a second pulse of energy.

  • Patent number: 6829239
    Abstract: A LAN modem permits unambiguous routing for multiple workstations located on a LAN to each gain access through the LAN modem to any one of a number of different remote servers located on a number of different remote networks using a combination of public port number and public address of the workstation. There are instances where sessions are changed between the same workstation/server. This changing of sessions changes the public port numbers associated with each session, which destroys the above unambiguous routing, since the combination of a public destination IP address and a private destination port number is no longer the same unique value contained in an address translation table of the LAN modem. A four step hierarchical procedure is provided in which the LAN modem determines which workstation the packet is to be routed based upon value of fields stored in the network address translation (NAT) table or value of fields stored in a static table.

  • Publication number: 20040236327
    Abstract: A spine stabilization system having one or more flexible elements with tubular structures with openings or slits. The flexible elements may limit rotation, flexion-extension, or lateral bending of the spine. The system also may have a locking mechanism that secures one or more flexible elements in a rigid configuration. A flexible element may be disposed within another flexible element, and the slits may form helical patterns on the tubular structures. The flexible element may be conformable to the natural spinal movement.

  • Patent number: 6746046
    Abstract: A dual flow inflator for airbags is disclosed, together with related manufacturing, installation, and deployment methods. The inflator may have a gas chamber with a first end with a first exit orifice and a second end with a second exit orifice. The exit orifices may be directed into inlet ports of an inflatable curtain so that inflation gases exit the inflator through the exit orifices and enter directly into the inflatable curtain. The exit orifices may provide axial gas flows in opposite directions so that each gas flow neutralizes the thrust of the other. The exit orifices may comprise frangible structures such as burst discs, scored surfaces, and compression closures. If desired, pistons may be utilized to ensure that the exit orifices are completely and simultaneously opened. Furthermore, the gas chamber may comprise a variety of configurations, including a unitary, one-piece structure, a multi-part structure with vessels attached to a tubular or spherical bulkhead, or a generally spherical shape.

  • Publication number: 20040098015
    Abstract: The present invention is directed to an inflatable device for use in restoring the anatomy of diseased or fractured bone. The inflatable device may be a balloon of varied size or shape to conform to the bone to be treated and may be deployed in any type of bone where collapsed fractures of cortical bone may be treated by restoring the bone from its inner surface. Once the bone has been sufficiently restored the balloons may be deflated and removed, or may remain inside the bone. The balloon may have multiple layers to provide desired surface characteristics, resistance to puncture and tearing, or other beneficial properties, as appropriate for the particular application of the device.

  • Publication number: 20040089642
    Abstract: A system for laser marking a gemstone (10) is provided. A pulsed laser (20) generates a laser pulse (40) which is then directed towards a focusing element (60) through optical means (30). Lens (60) focuses the laser pulse into focused pulse (70). The focused pulse (70) is projected onto a surface of gemstone (80) which is mounted in fixture (90). A computer control system (110) allows a user to input and control a predetermined path of displacement between the gemstone (80) and the focused laser pulse (70).
