Patent CA-2302022-A1 (CA)
Title: Conversion of international mobile station identity (imsi) number
Inventor: CHANDNANI VISHAL SHAM
IPC: H04W92/02
Filed: 2000-03-22
Abstract: A unique method and apparatus for allowing a wireless communication system to offer increased IMSI number functionality and corresponding global roaming capability by converting an identification number received from a particular mobile station in the wireless communication system in a first format to a second format which allows for use of more information included in the identification number is disclosed. A  variable length IMSI number in TIA/EIA/IS-95 format is received at a base station in encoded form. The base station decodes the parameters included in the IMSI number into their original decimal values, and, if all parameters have not been sent in accordance with the IMSI type, will add the proper values for the unsent parameters. The MCC, IMSI_S, and IMSI_11_12 parameters of the IMSI number are then stored in a 15-digit IMSI  array. The contents of each location of the 15-digit array are associated with a specific location in an 8-octet structure which is required by ANSI/TIA/EIA-41. The value in each location of the array is converted to Binary Coded Decimal (BCD) format and mapped to its associated location in the 8-octet structure. The IMSI number will then be in a format compliant with ANSI/TIA/EIA-41, thus allowing a service provider to offer increased IMSI functionality to its customers and allow the IMSI number to be used as a national mobile station identifier.

Title: Defocusing polymer attenuator
Inventor: DELISLE VINCENT
IPC: G02F1/313
Filed: 2000-04-27
Abstract: An optical attenuator in the form of a polymer having the property of variably defocusing a beam of light is disclosed. The optical attenuator includes a variably and reversibly deformable lens inserted in the path of a beam of light and a control means capable of controllably deforms the deformable lens such that the focal length of the lens is varied. The deformation of the lens ranges between an absence of deformation (infinite focal length) where the beam of light passing therethrough is not altered by the lens, to a maximum deformation where the beam of light is maximally attenuated (the smallest focal length). Moreover, the change in the focus position attenuates the beam of light without creating any polarization dependence loss.

Filed: 2000-05-12
Abstract: An operator control system for controlling the operation of an electric motor driven door or gate operator unit having a speed reducing gear drive mechanism and a brake unit for positive braking of the motor output shaft. A programmable microcontroller is operably connected to a motor drive circuit with interlock relays to energize the operator unit drive motor for rotation in opposite directions. The motor drive circuit is interconnected with a motor watchdog circuit to effect motor shutdown if the microcontroller malfunctions. The motor drive circuit is operably connected to a brake release circuit to prevent motor operation unless the electrically operated brake is energized to release braking of an operator output shaft. The microcontroller receives input signals from manually or radio-controlled door open, close and stop switches and from door position limit switches. The microcontroller is connected to a non-volatile memory for storing door mid-stop time delay values, braking rates, a door position limit overrun signal, a door cycle count, door reversals upon receiving an obstruction detector signal and error codes associated with door operator and control system malfunctions. The door may be operated to provide a down position limit overrun, progressive braking and a mid-stop set position by time based signals. The electrically operated brake may be controlled on a variable duty cycle to provide smooth braking action in both directions of movement of the door.

Title: Connection set-up and path assignment in wavelength division multiplexed ring networks
Inventor: ELLINAS GEORGIOS NICOS
IPC: H04B10/275
Filed: 1999-01-19
Abstract: Techniques for physically implementing fiber ring networks which achieve full mesh connectivity, such networks including a 2-fiber WDM ring network composed of a clockwise ring, and a 4-fiber WDM Self-Healing Ring Network. The number of wavelengths required is derived for both odd and even number of nodes (901-904) on the ring. To physically set-up all required connections in the network, optimal wavelength assignment algorithms are devised so that the wavelength assignment between nodes (901-904) on the ring is systematic and engenders full mesh connectivity while avoiding any possible violation of the color clash constraint. An illustrative algorithm uses a simple matrix approach for calculating the interconnection arrangement.

Abstract: A system for sensing subterranean acoustic waves emitted from an acoustic source includes a plurality of laser sources, a plurality of subterranean optical sensors, at least one optical detector, and electronics. The laser sources each emit light at a different frequency. The subterranean optical sensors receive the light and alter the light in response to the acoustic waves. The optical detector receives the altered light and outputs an electrical signal. The electronics receives the electrical signal and converts it into seismic data format. Preferably, the light emitted from the optical sources is modulated at a plurality of modulation frequencies. The electronics can be used to demodulate the signal. The electronics may demodulate the electrical signal by mixing the signal with periodic waveforms having frequencies corresponding to the modulation frequencies and twice the modulation frequencies. The modulation frequencies are selected such that at least one of the second harmonic frequencies associated with the modulation frequencies is interleaved in a non-interfering manner within the corresponding set of first harmonic frequencies. Preferably, the modulation frequencies are selected such that at least one of the first harmonic frequencies is interleaved in a non-interfering manner within the corresponding set of modulation frequencies.

Abstract: An operator-actuated inlet grate clean-out mechanism which can be actuated by pushing and pulling a cable or rotating a shaft from the driver's seat of a boat. A weed wiper which is arranged to push weeds off of a pivotable cantilever-tine inlet grate as the wiper travels along the tines and toward the aft tips of the tines. As the wiper sweeps along the inlet grate tines, it bears against the inlet grate and causes the grate to swing downward to a position where the aft tips of the cantilever tines are spaced from the pump jet housing. Because the weeds wrap and ball around the inlet grate, they also slide off easily when pushed or dragged by the sweeping wiper bar.
