Title: Signal quality determining device and method
Inventor: BEERENDS JOHN GERARD
IPC: G10L25/69
Filed: 1996-03-13
Abstract: A device for determining the quality of an ouput signal to be generated by a signal processing circuit with respect to a reference signal is provided with a first series circuit for receiving the output signal and with a second series circuit for receiving the reference signal and generates an objective quality signal by means of a combining circuit coupled to the two series circuits. The poor correlation between said objective quality signal and a subjective quality signal to be assessed by human observers can be considerably improved by reducing, in a differential arrangement, present in the combining circuit, for determining the difference between the two series circuit signals, said difference by a certain value, preferably as a function of a series circuit signal, and the poor correlation can be further improved by disposing a scaling circuit between the two series circuits for scaling at least one series circuit signal, it is furthermore also possible to scale the quality signal as a function of said scaling arrangement.

Title: Radially-enlargeable ptfe tape-reinforced vascular grafts and their methods of manufacture
Inventor: PETERSON ROBERT
IPC: A61F2/06
Filed: 1996-04-15
Abstract: A method for improving the radial enlargeability and other properties of tape-reinforced tubular vascular graft formed of sintered fluoropolymer(s), such as expanded, sintered PTFE. Broadly, the method comprises the step of radially shrinking the reinforcement tape layer of the graft, or the entire tape-reinforced graft, after sintering thereof. Such radial shrinkage of the reinforcement tape layer, or of the entire graft, renders the graft subsequently radially enlargeable by more than 5%, without tearing or breaking of the reinforcement tape layer of the graft. Radially enlargeable grafts of the present invention may be combined with various types of stents or anchoring systems, to form endovascular graft devices which are transluminally insertable and implantable within the lumen of a host blood vessel. Alternatively, radially enlargeable grafts of the present invention may be implanted by way of traditional surgical graft implantation techniques, without any radial enlargement of the graft at the time of implantation, so as to take advantage of the improved strength properties and suture-holding properties of the radially-shrunken tape-reinforced grafts of the present invention.

Title: Thermally-inhibited pregelatinized non-granular starches and flours and process for their production
Inventor: CHIU CHUNG-WAI
IPC: A23L1/0522
Filed: 1996-05-16
Abstract: Thermally-inhibited, pregelatinized non-granular starches and flours are prepared by pregelatinizing the starch or flour and thermally inhibiting the starch or flour by dehydrating the starch or flour to anhydrous or substantially anhydrous and then heat treating the dehydrated starch. The pregelatinization may be carried out prior to or after the thermal inhibition using known methods which disrupt the granular structure such by drum-drying or jet-cooking and spray-drying. Preferably the starch or flour is adjusted to a pH above 7.0 prior to the thermal inhibition. The starch may be dehydrated by heating the starch in a suitable heating apparatus, by extracting the water from the starch using a solvent such as ethanol, or by freeze-drying the starch. Preferably the starch or flour is treated with a solvent to remove proteins and/or lipids and thus prevent off flavors.

Title: Method of inhibiting viral replication in eukaryotic cells and of inducing apoptosis of virally-infected cells
Inventor: ANDRUS LINDA
IPC: A61K45/00
Filed: 1996-06-05
Abstract: The present invention is directed to methods which inhibit post--translational hypusine formation in the intracellular protein eIF-5A, to suppress infections by virases that parasitize eIF-5A to promote their own replication.

Title: Improved system for routing packet switched traffic
Inventor: HAN YIH-WU
IPC: H04Q11/04
Filed: 1998-03-10
Abstract: The system of the invention uses ATM switches as high performance Internet routers by using standard ATM signaling to set up cut-through paths. The cut-through paths are Switched Virtual Paths which are shared with similar flows toward the same destination and a similar Quality of Service (QOS). The concurrency of multiple flows is achieved by using a different Virtual Channel Identification (VCI) for each flow. The cut-through paths are reused to minimize the overhead associated with setting up and tearing down the paths. Depending on the needs of the traffic, different SVCs having different QOS and different bandwidths can be used. Customer service needs and traffic measurements data are used to identify potential cut-through paths. Once a cut-through path is set up, IP mechanisms are used to update the routing tables of related routers and ATM hosts. Specifically, IP protocols' adjacency bring-up procedures and reachability exchanges are used to update routers' routing tables, and ICMP redirect messages are used to update ATM hosts' routingtables. All ATM QOS are available for the cut-through paths.

Abstract: A method and apparatus for wrapping and securing film about a load by positioning a first arm retaining an end portion of film toward the load, wrapping a layer of film about the first arm so the first arm is between the wrapped film and the load, withdrawing the first arm retaining the film from between the wrapped film and the load, and releasing the end portion of film retained by the first arm to position and secure a first film portion between the wrapped film and the load. The load is further wrapped and a second arm is subsequently positioned toward the load, and a layer of film is wrapped about the second arm so the second arm is between the wrapped film and the load. A roped film portion is captured and retained by the first and second second arms. The roped film is then severed and an end portion of the severed film is retained by the first arm for subsequently wrapping another load. The other end of the severed roped film portion is retained by the second arm, which is withdrawn from between the wrapped film and the load to position and secure a second film portion between the wrapped film and the load. The arms are withdrawn along a relativelystraight path by laterally translating the arms while pivoting thereby reducing contact between at least the portion of the arm retaining the film tail and the wrapped film.

Abstract: A method and apparatus allows a session key for a encrypted message to be recovered even if the recipient loses or forgets his private key.  A session key encrypted using the public key of a party other than the intended recipient of the message is transmitted to the third party such as a certificate authority, who uses an identifier to retrieve private information known to the intended recipient of the message.  The third party can compare the private information with private information provided by the party claiming to be the intended recipient.  If the private information retrieved matches or nearly matches the private information provided, the third party can decrypt the session key using the third party's private key and provide the session key to the intended recipient.  The intended recipient can then use the session key to decrypt the message, without making available the intended recipient's private key to any party other than the intended recipient, or storing the intended recipient's public key on the third party's system.  Law enforcement agencies can intercept the message and the session key encrypted with the third party's public key and can provide to the third party a court order to retrieve the session key to decrypt the message without notifying the intended recipient.
