Abstract: An angled fixation device, such as an angled screw. This angled fixation device may be used by the surgeon to secure a spacer to a spinal disc space. The proximal end portion of the angled fixation device is driven perpendicular to the anterior wall of the spacer, and so is parallel to the vertebral endplates and in-line with the inserter. The distal end portion of the angled fixation device is oriented at about a 45 degree angle (plus or minus 30 degrees) to the vertebral endplate it enters.

Abstract: Methods for securing a intervertebral cage to one or more levels of the spine with fixation. The fixation, which is typically a staple, is intended to be driven perpendicular to the proximal face of the cage and in-line with the inserter. After the cage is placed and positioned according to surgeon preference, a single piece fixation clip is then deployed and fixed in a manner that produces a zero-profile device.

Abstract: Various methods and devices for performing arthroscopic surgery are provided. In particular, methods and devices are provided for reshaping, unclogging, and vibrating tubing of an aspiration pump in a fluid management system. For example, a fluid management system is provided that includes a valve assembly disposed on a housing and configured to selectively pinch closed tubing disposed within a first pathway and a second pathway. The valve assembly is configured to bias tubing disposed within the first and second pathways to an open position after the tubing is pinched closed by the valve assembly. As another example, a fluid management system is provided that includes a vibratory mechanism coupled to a valve and configured to vibrate the valve so as to facilitate the flow of debris through tubing disposed within first and second tubing pathways.

Abstract: A method of analysis for detecting and reporting the presence of low levels of ionizing radiation in spaces such as cargo shipping containers. Radiation detectors are placed inside the containers and the method is invokable while the containers are in transit. The difference between radiation emanating from inside the container and radiation emanating from outside the container is determined to detect and identify low levels of radiation. The detected and identified radiation is comparable with the container manifest to determine whether the radiation is from sources identified in the manifest or is likely to be contraband.

Abstract: A transmission system and method for operating the transmission system, where the transmission system includes a selector assembly arranged to select between gear ratios instantaneously without substantial power interruption. The selector assembly includes first and second sets of engagement members and an actuator system. The actuator system may have a first actuator member for moving the first set of engagement members, a second actuator member for moving the second set of engagement members, a first actuator device for actuating the first actuator member and a second actuator device for actuating the second actuator member independently of the first actuator device.

Abstract: Disclosed are a system and method for providing certifiable shielded cabinets and rooms, or pods, to protect devices, equipment and people from electromagnetic interference such as electromagnetic pulse, and directed energy attack. The method simulates the separate electric and magnetic shield requirements and capabilities of each type of materials, simulating them separately and together to form a combined set of materials layered for an enhanced electromagnetic shield that is lighter weight and less expensive. Further disclosed is a system and method for SCADA, RFID, and OID monitoring and controls to enable initial and ongoing testing and control.

Abstract: A free space optical communication network includes plural stations, some capable of functioning as both transceivers and repeaters, and to a station having such capability. The stations include a transmitter array having many optical emitter elements, each having an associated beam and a receiver having a receiver array with many optical detector element areas having beams corresponding with the beam of an emitter element of a transmitting optical station of the network. An optical arrangement associated with the arrays and the arrays themselves are such that beams associated with different elements of each array can be coupled with different stations of the network.
