Title: Polyaxial bone fixation element
Inventor: KEYER THOMAS
IPC: A61B17/70
Filed: 2008-07-21
Abstract: The present invention is directed a polyaxial bone fixation element for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The polyaxial bone fixation element preferably includes a bone anchor, a collet, a body, and a locking cap. The polyaxial bone fixation element preferably enables in-situ assembly. That is, the polyaxial bone fixation element is preferably configured so that in use, the bone anchor may be secured to the patient's vertebra prior to being received within the body. Accordingly, the polyaxial bone fixation element enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body can be snapped-onto the bone anchor. The bone anchor preferably also includes a second tool interface so that a surgical instrument can be directly coupled to the bone anchor.

Abstract: This invent is a new construction of disc-type motors. It features: single stator, double rotors, double coil-slot in both faces of stator core, Ring-like coil, and ferrite stator core.   In order to explain working principle conveniently, take an synchronous motor as an example. In fig.2, stator core (8) is assembled to frame (10) with supports(9), there are slots in both two faces of stator core(8), in which each plane faces a permanent magnetic steel(11) in rotor(6) and(12). The moving interval space is about 1mm. Ring-like coils(19) stride over stator core(8) and round in two opposed slots. The opposed permanent magnetic steel(11) in rotor(6) and (12) are same magnetic property. (in fig 2, at this moment, the above magnets are N poles and below are S poles). The bellow magnetic lines of flux flow from stator(8) to above magnetic steels in both two rotors, through rotor yokes (6) and (12) , magnetic lines of flux go to above two magnetic steels, at last return back to stator core.  This process forms a ring of magnetic lines of flux. The electric current in above Ring-like coil is in clock-wise, and below is in counter-clock-wise, obviously the whole coils are receiving the same direction moment, and the motor begins to run.

Title: Connector for multiple optical fibers and installation apparatus
Inventor: FRASER ALEX
IPC: G02B6/28
Filed: 2008-06-16
Abstract: The present invention comprises a connector comprising shape memory material such as a shape memory alloy, an optical fiber conduit and an axial stress opening traversing the connector from the connector surface to the fiber conduit and along at least a portion of a longitudinal length of the connector. The fiber conduit is dimensioned for optical fibers and to secure two optical fibers in abutment alignment for light signal transmission from one fiber to the other, with minimal attenuation and for securing the fibers without crushing or other damage to the fibers. In another embodiment, the present invention relates to a method of bringing optical fibers in abutment connection for signal conduction using a connector as above, wherein a wedging force is applied to the stress opening, whereby the wedging force will induce separation of the side walls of the slot and expansion of the fiber conduit for insertion of optical fibers and their abutment connection and securing of the fibers in abutment connection, when the wedging force is removed. Alternatively, a force may be applied to either side of the stress opening to again expand the opening and fiber conduit for the purpose of placement of optical fibers within the fiber conduit. Removal of the force will allow retention of the fibers in abutment connection of the fibers.  In a still further embodiment, the present invention relates to an apparatus which applies a wedging force to a stress opening for expansion of a fiber conduit and insertion of optical fibers and their retention, light transmission abutment and connection in a connector as above.

Abstract: The functionality of communications standards and protocols that are application-layer specific are overlaid on an IP -based infrastructure, by employing an IP DNS server as the registration host for IP and other communications standards based and protocol based communications. Communication can occur at either the IP layer or the communications standards or protocol application layer. At the IP layer, a host application can interrogate network nodes. To extend this service to other communications standards or protocol communications, device registration and resolve services are implemented on the DNS server. Similar to the manner in which an IP -based service uses a native, IP -based DNS resolve request, a host can utilize a resolution request against the communications standards and protocol- enabled DNS server for standards and protocol application-layer interrogation of endpoints.
