Title: Channel and data link automatic restoration
Inventor: THIELER STEPHEN M
IPC: H04L69/40
Filed: 1997-08-20
Abstract: A communication switching system having a plurality of switch nodes with each of the switch nodes responsive to a failure of a communication link within a group of communication links to switch active calls from channels of the failed communication link to idle channels of other communication links within the group of communication links. If no idle channels are available within the group of communication links when the communication link fails, a predefined time is waited for a channel to become idle or a new communication link to be added to the group of communication links before the active channels are abandoned. Advantageously,the switching of the active calls to idle channels occurs quickly so that only amomentary interruption of the calls occurs. The group of communication links mayadvantageously be a non-facility access service (NFAS) group having a combination of ISDN BRI and PRI communication links. The calls can be either voice, video, or data calls.

Title: Frequency tracking for communication signals using m-ary orthogonal walsh modulation
Inventor: VIJAYAN RAJIV
IPC: H04B1/7085
Filed: 1997-03-26
Abstract: A frequency tracking loop for a communication system using orthogonal Walsh modulation is provided. The frequency tracking loop includes a correlator (120) such as a fast Hadamard transformation device, and a discriminator (130). The correlator (120) produces a correlation vector (122) representing the result of correlating the input signal with each of a set of Walsh functions, with corresponding index values. The discriminator (130) produces a frequency error signal (ê) based on the correlator (120) output with the highest energy level and other correlator outputs whose indices are related to the index of highest energy correlator output by powers of two. The frequency error signal (ê) is generated by producing a cross product between the highest energy output and one or more of the other related correlator outputs. In further aspects, a filter (140) can be used to further shape the resulting error signal (ê) and form a frequency offset estimate signal (f).

Title: Secure flexible electronic submission acceptance system
Inventor: LAU TERENCE CHUN-YAT
IPC: G06F21/64
Filed: 1998-05-14
Abstract: In an electronic filing system over a computer network, a central server sets the requirements for making submissions. These requirements include a time limit after the expiry of which, submissions will no longer be accepted. A gateway server polls the central server for the submission requirements, and establishes a directory in its own file system to which all potential submitters have write access until expiry of the time limit. On completion of its submission, a submitter generates evidence of the complete submission. The evidence can be in the form of a message digest. The submitter encrypts the evidence using the gateway server's public encryption key and then forwards the encrypted evidence to the gateway server. If the evidence is filed before expiry of the time limit, the gateway server permits the evidence to be written to the directory established for the submission requirements. Once the submitter has successfully filed its evidence, it can forward the complete submission to the gateway server. When the gateway server receives the complete submission, it decrypts the evidence, it may check the submitter's digital signature on the evidence, and it then compares the complete submission with the evidence. If the evidence is a message digest, the gateway server computes a message digest of the complete submission. If the two digests are identical, then it is clear that the submission was completed when the evidence was filed, before expiry of the deadline, and the gateway server can then forward the submission on to the central server.

Inventor: KINER ROBERT SAMUEL
IPC: B65B9/067
Filed: 1996-10-01
Abstract: A method and apparatus for feeding resiliently compressed articles into a form/fill/seal machine. The method includes steps of receiving horizontally compressed articles into an infeed end of a pair of conveyor belts (60, 62), continuously conveying the compressed articles to a discharge end, continuously forming a plastic film around the pair of cantilevered conveyor belts without the stack of articles exerting expansion force against the plastic film, forming and sealing a closed tube, and releasing the stack of compressed articles into the closed tube only after the seal has sufficient strength to maintain the stack of articles compressed. The pair of conveyor belts (60, 62) has rigid conveyor backing members (44, 46) and cantilevered ends (48, 50) with a discharge pulley (54, 58) mounted at each cantilevered end. At least one tie bar connects the backing members near the cantilevered ends in order to resist the expansion force of one or more stacks of resiliently compressed articles between the conveyor belts.
