Patent CA-2607317-A1 (CA)
Inventor: GILES RANDY CLINTON
IPC: H04L9/08
Filed: 2006-04-25
Abstract: A communication system adapted to use wavelength (frequency) division multiplexing for quantum-key distribution (QKD). In one embodiment, a communication system of the invention has a transmitter coupled to a receiver via a transmission link. The transmitter has (i) a first optical-frequency comb source (OFCS) adapted to generate a first plurality of uniformly spaced frequency components and (ii) a first multi-channel optical modulator adapted to independently modulate each component of the first plurality to produce a quantum-information (QI) signal applied to the transmission link. The receiver has (i) a second OFCS adapted to generate a second plurality of uniformly spaced frequency components and (ii) a second multi-channel optical modulator adapted to independently modulate each component of the second plurality to produce a local- oscillator (LO) signal. Each of the first and second optical-frequency comb sources is referenced to a frequency standard such that the frequency components generated by these comb sources have substantially the same frequencies. The receiver employs a multi channel homodyne detector adapted to process interference signals produced by combining the LO signal with the QI signal to ascertain quantum information carried by the QI signal.

Title: Electronic overload relay for mains-fed induction motors
Inventor: COLBY ROY STEPHEN
IPC: G01R31/34
Filed: 2006-05-01
Abstract: An induction motor having a rotor and a stator is protected during running overloads by connecting the motor to an overload protection relay that can be tripped to interrupt power to the motor in the event of an overload, tracking the stator winding temperature of the motor during running overloads with a hybrid thermal model by online adjustment in the hybrid thermal model, and tripping the overload protection relay in response to a predetermined running overload condition represented by the tracked stator winding temperature. In one embodiment of the invention, the stator winding temperature is tracked by use of an online hybrid thermal model that uses the resistance of the rotor as an indicator of rotor temperature and thus of the thermal operating conditions of the motor. The hybrid thermal model incorporates rotor losses and heat transfer between the rotor and the stator, and approximates the thermal characteristics of the rotor and stator.

Title: Variable length coding method and variable length decoding method
Inventor: KONDO SATOSHI
IPC: H04N19/176
Filed: 2002-11-22
Abstract: According to the present invention, an image coding apparatus provides a run-length encoding unit RLE1 that subjects quantized coefficients which are obtained by quantizing frequency components of an image signal to a variable length coding process by using a run value Run that indicates the number of successive zero coefficients and a level value Lev that indicates a value of a non--zero coefficient following the zero coefficients. The run-length encoding unit RLE1 includes an reordering unit Lreodr for reordering level values Lev; a variable length coder LVLC for coding reordered level values ROLev by using a code table that is selected according to the value of a quantization parameter QP; a reordering unit Rreodr for reordering run values Run from high frequency component of the quantized coefficients to low frequency component;  and a variable length coder RVLC for coding reordered run values RORun by using a code table that is selected according to the number of already-processed run values.    Accordingly, a variable length coding process for quantized coefficients is carried out at a higher coding efficiency, with redundant information included in the coefficients being effectively reduced.
