Title: Tcp normalization engine
Inventor: MCGEE WILLIAM
IPC: H04L29/08
Filed: 2005-07-28
Abstract: The present invention relates to network security systems and, more particularly, to a method and apparatus for maintaining a TCP connection when the payload data of a TCP segment transmitted from source to destination is modified. The present invention allows the payload data of a TCP segment to be modified and, specifically, changed in length by an intermediate device during a. TCP connection between any two hosts while adhering to the semantics of the TCP protocol so that the TCP connection may be maintained. More specifically, the invention comprises, in a TCP normalization engine communicating with a source and a destination, a method of maintaining a TCP connection between the source and the destination during modification of a payload associated with a TCP  segment, the method comprising: receiving the TCP segment from the source at a process incoming module; determining if the TCP segment contains payload data; if the TCP  segment contains payload data, invoking a process ack module and a process seq module, wherein the process seq module processes the payload data to determine if a payload correction is required; if a payload correction is required, updating a state table and modifying the payload data to reflect the payload data correction; modifying the TCP segment with at least the modified payload data; and forwarding the modified TCP segment to the destination. Advantageously, this approach allows payload data content to be changed flexibly in order to remove or neutralize protocol violations or attacks.

Title: Syntactic inferential motion planning method for robotic systems
Inventor: JOHNSON STEPHEN WAYNE
IPC: B25J9/16
Filed: 2004-01-30
Abstract: A method and system for planning and optimizing the movement of a robotic device comprises establishing a plurality of spatial locations where the device can possibly be positioned and establishing rule sets for constraining movement of the robotic device between the locations. Once a start and end point have been determined, the method of the invention calculates all possible routes for the device to move, via the established locations and following the constraints of the rule sets. The calculated routes are then compared to a criteria, such as minimizing time, and an optimum route, meeting the desired criteria is determined. The calculated routes may also be cached for future access. The invention also provides for an error recovery method for allowing a robotic device to recover should it encounter an error.

Title: Compact full-traction differential
Inventor: GLEASMAN KEITH E
IPC: F16H48/28
Filed: 2003-12-31
Abstract: The size, weight, and cost of a full-traction differential are significantly reduced by the synergism of several interrelated design features of a cartridge-like gear complex: (1) Each combination gear has only a shallow journal hole in each end of an otherwise solid gear body, being supported on mating hubs fixed to mounting plates slipped into a one-piece differential housing. (2) The solid worm-wheel portion of the combination gears has a deeper hour-glass shape. (3) Mating worm/worm-wheel teeth have a broad "supra-enveloping" contact pattern on only the drive side of the mesh. (4) The side-gear worms have closed-end teeth. (5) Both diameter and axial length of the side-gear worms are reduced by a special cutting process. The efficiency of the differential is increased by a thrust plate supported in the mounting plates and positioned between inner ends of the side-gear worms.

Title: Hardware accelerator state table compiler
Inventor: NG SAI LUN
IPC: G06F9/45
Filed: 2003-10-03
Abstract: Error-free state tables are automatically generated from a specification of a group of desired performable functions, such as are provided in a programming language in a formal notation such as Backus-Naur form or a derivative thereof by discriminating tokens corresponding to respective performable functions, identifications, arguments, syntax, grammar rules, special symbols and the like. The tokens may be recursive (e.g. infinite), in which case they are transformed into a finite automata which may be deterministic or non-deterministic. Non-deterministic finite automata are transformed into deterministic finite automata and then into state transitions which are used to build a state table which can then be stored or, preferably, loaded into a finite state machine of a hardware parser accelerator to define its personality.

Title: Reliable back-up storage of electrical energy meter reading using writable passive radio-frequency identification (rfid) devices
Inventor: NAIK KSHIRASAGAR
IPC: G01R22/06
Filed: 2005-10-27
Abstract: A reliable back-up storage unit to save the reading of an electrical energy meter to be read over a wireless link in an automatic meter reading (AMR) system. An electrical energy meter in an AMR system records the data, representing the total amount of electrical energy consumed, in a back-up storage unit on a periodic basis. The back-up storage unit is physically separated from the main module for energy measurement, but lies within its communication range so that data can be written into the back-up storage unit. The back-up storage unit is implemented using repeatedly writable passive radio-frequency (RFID) technology. By making the RFID device passive and positioning it away from the main measuring module, the reliability of the back-up storage unit is enhanced. While the main measuring module is functioning without fault, the module reports meter readings to an external system on a periodic basis or on a demand-driven basis. On the other hand, when the main measuring module has failed, a separate external data gathering system reads the contents of the back-up storage unit. The objective of having such a reliable data back-up unit in an AMR based electrical energy meter is to facilitate utility companies to read the last meter reading in a failed energy meter. The new invention can also be applied in other AMR systems, for example, for gas and water.
