Title: Improvements in communication security
Inventor: ABDULKADER BARBIR
IPC: H04L29/06
Filed: 2000-12-29
Abstract: This invention provides an improved mechanism to guard against message sequencing threats. It can be used in any system which makes use of a transform which uses a state machine such as encryption/decryption and compression/decompression systems, and where the transform and the inverse transform use the same state machines. The invention is implemented as a matching pair of applications at both ends of a transmission link. The transmitting end encodes the current value of a particular state using a one-way hash function and adds this value as a field in the transmitted packet. At the receiving end, the packet is passed to the decoding algorithm which derives the current value of the same state, and passes it through the same one way hash function. The receiver can compare the result of these operations with the value in the field sent by the transmitting end.

IPC: F01C1/04
Filed: 1999-05-20
Abstract: A rotary machine having a rotatable outer drum (10) within which rotates on a different axis a rotor (13). The space between the outer drum and the inner rotor is divided into discrete arcuate compartments by vanes (15) extending across the space between the two rotating parts such that the volume of the compartments (16) varies cyclically during rotation. The vanes are rigidly attached to one of the rotating parts and extend across the space into contact with the other of the rotating parts during at least a part of the rotation of the machine. The vanes may co-operate with sliding shoes (17) or fixed grooves (20) which latter may be cylindrically formed as at (24). Such a machine may be used as an enhancement of the efficiency and economic operation of an internal combustion engine which in certain cases can overcome the problems of throttle loss at low engine speeds, or it may operate as a heat pump.

Title: Polypeptides and polynucleotides from coagulase-negative staphylococci
Inventor: FOSTER TIMOTHY J
IPC: A61P31/04
Filed: 1999-08-31
Abstract: Isolated proteins, designated SdrF, SdrG and SdrH, and their corresponding amino acid and nucleic acid sequences are provided which are useful in the prevention and treatment of infection caused by coagulase-negative staphylococcal bacteria such as S. epidermidis. The SdrF, SdrG and SdrH proteins are cell-wall associated proteins that specifically bind host proteins and which each have a highly conserved motif of which the consensus  sequence is TYTFTDYVD. The proteins, antigenic portions thereof and anti-Sdr F, SdrG and SdrH antibodies are also useful for the identification and diagnosi s of coagulase-negative staphylococcal infections. In particular, the proteins  are advantageous because they may be used as vaccine components or antibodie s thereof, and they may be administered to wounds or used to coat biomaterials  to act as blocking agents to prevent or inhibit the binding of coagulase- negative staphylococci to wounds or biomaterials.

Title: Lighting control interface
Inventor: MUZZIN MARK A
IPC: H05B37/02
Filed: 2001-05-08
Abstract: A lighting control interface consisting of a touch pad matrix, a housing, different faceplates having unique graphical designs, and a control circuit. The touch pad matrix has a plurality of conductive touch pads. The faceplate has a plurality of faceplate areas which are used to designate various lighting commands and each faceplate can represent a unique collection of lighting control functions. The control circuit is electrically coupled to the touch pad matrix and is programmed to support the functionality represented by a particular faceplate design by ascribing the appropriate lighting control functions to the individual touch pads. The control circuit includes an oscillator which is coupled to each touch pad in turn and a microcontroller which monitors the frequency of the oscillating circuit when connected to the various touch pads. When a user places a finger on a touch pad, the frequency of the associated oscillations decreases and this decrease in frequency is detected by the microcontroller. Upon detecting the activation of a touch pad, the microcontroller determines which faceplate area has been selected by the user by mapping the touch pad location to the associated faceplate. The microcontroller also detects slow, long and double activations of the faceplate where necessary. A corresponding lighting signal is generated by microcontroller and provided by the lighting control interface either for local dimming purposes of for use within a larger networked lighting environment.

Filed: 2001-05-07
Abstract: Hydraulic assembly tool having a tool fixed portion having a proximal end and a distal end. The tool fixed portion includes a hydraulic cylinder having a fluid pressure port at the proximal end of the tool fixed portion.      The fluid pressure port is for receiving a fluid having a controllable pressure. The tool fixed portion includes a fixed jaw. The tool also has a moveable portion including a moveable jaw and a piston disposed in the hydraulic cylinder, the piston receiving a hydraulic force from the pressurized fluid. There is a compression spring engaging the tool fixed portion and the tool moveable portion, the compression spring urging the tool moveable portion including the moveable jaw in a direction opposite the direction of the hydraulic force. Increasing the pressure of the fluid causes the moveable jaw to move in the direction of the hydraulic force, and decreasing the pressure of the fluid permits the spring to move the tool moveable portion including the moveable jaw in a direction opposite the direction of the hydraulic force.

Inventor: DESIMONE JOSEPH M
IPC: B05D7/24
Filed: 1999-10-08
Abstract: L'invention concerne un procédé de revêtement d'un substrat, qui consiste à immerger une partie superficielle d'un substrat dans une première phase liquide ou supercritique. Cette première phase comprend un anhydride carbonique, et une matière de revêtement telle qu'un polymère. Le substrat est ensuite retiré de la première phase et placé dans une deuxième phase distincte, telle qu'un atmosphère gazeux, afin de réaliser un dépôt de la matière de revêtement sur ladite partie superficielle. L'étape de retrait est suivie de la séparation de l'anhydride carbonique de la matière de revêtement (par exemple, par évaporation, aération, chauffage, etc.), de sorte que la matière de revêtement soit retenue en tant que couche de revêtement formée sur la partie superficielle.

Patent CA-2350987-A1 (CA)
Title: System with choke in parallel with a/c line for load conditioning
Inventor: GRAY RICHARD
IPC: H02M1/12
Filed: 1999-11-19
Abstract: A choke coil (104) placed in parallel with the A/C line (109), that is, preferably across the A/C line's "hot" and "common" lines (109), quenching the reflected signal (or back emf) that is developed when any power amplifier or other load places its demands upon the incoming A/C power line (201). Due to its electromagnetic characteristics, the choke (102) tends to provide a momentary high current source of energy when needed by, the load when transient demand is called for.  The parallel choke (102) approach tends to have a reversing effect on this signal, at least substantially reducing its presence on the A/C  line (109), providing a greatly enhanced A/C power line signal quality, without which the otherwise untreated signals are able to modulate the A/C line (109).
