Title: Method and apparatus for transport of communication signals over a public network
Inventor: MISKA RICHARD A
IPC: H04Q3/66
Filed: 1996-12-09
Granted: 1999-11-23
Abstract: A method and apparatus for transmitting signals at different rates  between  an  originating  device  and  a destination device.   The originating device generates a communication   signal,   including   routing   data,  for transmitting the communication signal at a native rate associated with the originating device.  The communication signal is received by a switch which analyzes the routing data  of  the  signal  to  identify  transmission  rates recognizable by the destination device and, if necessary, a transmission path for routing the signal across a backbone network at the native rate.   The system then determines whether to re-encode the signal for direct transmission at a different rate recognizable by the destination device, or to maintain the signal at the native rate for transmission either directly to the destination device or across the backbone network.   The signal is then transmitted.   A destination switch at the destination end analyzes  the communication signal to determine the final destination point; if necessary, it re-encodes the communication signal for transmission at a rate which is recognizable by the final destination point, and then transmits the signal to the final destination.

Title: Interbody bone implant having conjoining stabilization features for bony fusion
Inventor: BAGBY GEORGE
IPC: A61F2/46
Filed: 1996-12-18
Granted: 2006-11-07
Abstract: A bone joining implant has a rigid, implantable base body having an outer surface with at least one bone bed engaging portion configured for engaging between a pair of bone bodies to be joined. At least one spline is provided by the bone bed engaging portion, the spline being constructed and arranged to extend outwardly of the body and having an undercut portion. Upon implantation, the undercut portion of the implant is configured to engage with a bone bed provided in the bone bodies to be joined so as to provide instantaneous fixation there between. In one embodiment, the implant is a vertebral interbody fusing device. The base body is cylindrical and the spline is an undercut thread helically configured about the body. In another embodiment, the base body forms a bridging portion for encircling a vertebra to be removed, and splines in the form of strips of material extend outwardly of top-most and bottom-most portions of the body.      Each spline has a undercut portion such that each spline mates in interlocking engagement with top-most and bottom-most neighboring vertebra having bone beds for receiving the splines there along. The mid-most vertebra is then removed (corpectomy), after which an enforcing brace is received therein.

Abstract: A sleeve bearing (10) for use on rotary valve shafts (14) subjected to substantial operating pressures sufficent to extrude PTFE includes a cylindrical nonmetallic bearing jacket (11), preferably composed from PEEK. The bearing jacket has a cylindrical inner cavity (20) defined between opposite annular cavity end lips (22, 24) within which cavity is disposed a cylindrical PTFE liner (12). The annular cavity end lips on the inner surfac e of the cylindrical nonmetallic bearing jacket extend inwardly to an end lip surface wherein the diameter of said end lip surface is slightly longer than the diameter of the rotary shaft (14) of the control valve. A suitable adhesive is used to bond the liner (12) to the bearing jacket (11). The cavi ty end lips maintain the liner in position if the adhesive fails. The end lip construction and the close clearances between the end lips and the rotary shaft enable the PTFE liner to carry greater load than in other PTFE bearing constructions before beginning to extrude PTFE. After the PTFE liner begins to extrude PTFE, the close clearances ensure that any overloaded PTFE is maintained within the cavity (20) of the nonmetallic bearing jacket.

Title: Integrated resonant microbeam sensor and transistor oscillator
Inventor: BURNS DAVID W
IPC: G01L9/00
Filed: 1995-12-15
Granted: 2009-05-26
Abstract: At least one microbeam situated on a substrate, having a resonant frequency dependent on the strain on the microbeam which may be affected by the bending of the substrate. The beam or beams have sense and drive electrodes proximate to the beam or beams and form capacitors with a beam being the other electrode. The capacitance varies as the beam moves in vibration. The sense electrode is connected to an input of a transistor, such as the gate or base, and the drive electrode is connected to an output of the transistor. The transistor has a load impedance with a capacitive component to aid in the sustaining of vibration of the beam at a resonant frequency. A  high ohm resistor is connected between the gate and the drain of the transistor to appropriately bias the gate. The bending of the substrate may be caused by a magnitude of a physical stimulus being measured. However, the bending of the substrate is not utilized nor desired in the filter and temperature sensing configurations of the invention. The frequency of resonance is an indication of the magnitude of the physical parameter. Variants of the sensor may be implemented with different placements of the sense and drive electrodes, and additional electronics as needed to implement the various configurations and microbeam geometry. Additional sense and/or drive electrodes and beams also may be incorporated in the transistor resonant microbeam sensor.

Title: Call routing
Inventor: MCDONALD PAUL
IPC: H04M3/42
Filed: 1997-03-21
Granted: 2002-10-08
Abstract: A user profile for use, for example in a personal numbering service, has an associated confidence value for each of the destination terminal numbers in the profile, a confidence value representing the confidence of a call being successfully answered at the associated network terminal. When a service usi ng the profile needs to route a call for a user, the corresponding profile is accessed and the call is routed to the destination terminal number having th e highest confidence value. The profile is managed to modify the confidence values in dependence upon the outcome of the call, and also upon registratio n of a personal number user at a network terminal. The confidence values are probabilities and when one value is increased because of a successful outcom e, the other values are adjusted. The values can be a function of time to represent lessening confidence that a user is still at the network terminal of his last registration.

Abstract: Cameras are positioned so that they each view a different reflective surface of a polyhedron such as a pyramid. This results in each camera having a virtual optical center positioned within the pyramid. The cameras are positioned so that their virtual optical centers are offset from each other.

Title: Method and apparatus for compression compatible video scrambling
Inventor: RYAN JOHN O
IPC: H04N7/169
Filed: 1997-05-29
Granted: 2001-10-09
Abstract: Scrambling and descrambling techniques are described which, unlike many typical scrambling systems, are compatible with all conceivable forms of signal compression systems. The scrambling technique is based on the principle of applying local spatial distortion to the pixels in a video image, and the like, to locally displace the pixels from their normal locations. Most compression systems rely on the condition that good correlation exists in the image and that any small portion, i.e., pixel, in an image is very similar to the portions, or pixels, nearby. Since the present technique provides local spatial distortion which does not de-correlate the image and does not re-arrange the pixels in the image, the pixels near other pixels prior to application of the scrambling technique, have the same positional relationship after scrambling. The complementary descrambling technique restores the locally displaced pixels to their normal locations to restore the video image to its original unscrambled state.
