Patent CA-2341424-A1 (CA)
Title: Beam deflector and scanner
Inventor: AYE TIN M
IPC: G02F1/141
Filed: 1999-08-24
Abstract: A beam deflector (40) comprising a pair of mated microprism arrays (42 and 48) with one of the arrays comprised of a variable refractive index material (48) capable of being selectively changed in response to a field whose magnitude or intensity is regulated by regulating voltage applied. The other array (42) preferably is comprised of a material having a constant refractive index. A conductive layer (102 and 104 and 82) is disposed on both sides of the variable refractive index array. A pane (68 and 70) preferably is disposed in front and behind the arrays. Two pairs of the arrays can be arranged parallel to each other with their microprisms generally perpendicular forming a two-dimensional deflector. To achieve a deflection response time faster than 100 microseconds, each prism has a height no larger than about 20 micrometers and a width preferably no greater than about 100 micrometers. Preferably, each prism height is less than about 15 to about 10 micrometers to achieve a response time 30 microseconds or faster. A method of making the deflector includes using direct-write electron beam lithography to make a master for replicating arrays having a height of 10 micrometers or less. A pair of deflectors can be used to deflect a beam in two dimensions and can be used in a scanner. Where the beam is a laser, the deflector can be used in a laser imaging radar assembly. Such a scanner and laser imaging radar assembly provide fast scanning of an object or region advantageously without requiring the deflector to move during scanning.

Title: High frequency content recovering method and device for over-sampled synthesized wideband signal
Inventor: LEFEBVRE ROCH
IPC: H04Q7/22
Filed: 1999-10-27
Abstract: In a method and device for recovering the high frequency content of a wideband signal previously down-sampled during encoding, and for injecting, during decoding, this high frequency content in an over-sampled synthesized version of the wideband signal to produce a full-spectrum synthesized wideband signal, a white noise generator produces a white noise sequence. Serially interconnected gain adjustment unit, spectral shaper and band-pass filter spectrally shapes the white noise sequence in relation to a set of shaping parameters representative of the down-sampled wideband signal such as a voicing factor, an energy scaling factor, a tilt scaling factor, and linear prediction filter coefficients. A signal injection circuit finally injects the spectrally-shaped white noise sequence in the over-sampled synthesized signal version to thereby produce the full-spectrum synthesized wideband signal.

Patent CA-2354537-A1 (CA)
Title: Utilizing purge gas from ammonia synthesis
Inventor: WALLACE PAUL S
IPC: C01B3/58
Filed: 2000-02-03
Abstract: The invention provides an improved ammonium synthesis process. A synthesis gas is separated with a membrane into a hydrogen-rich gas and a hydrogen-depleted gas. The hydrogen rich gas is shifted with steam to convert carbon monoxide to carbon dioxide and hydrogen. Carbon dioxide is removed from the shifted gas, and remaining carbon oxides are methanized. This gas is admixed with nitrogen and with recycled ammonia synthesis feedstock gas. This ammonia synthesis feedstock gas is then cycled in an ammonia synthesis reactor. A purge gas stream is withdrawn from the ammonia synthesis feedstock gas and is admixed with the hydrogen-depleted gas. The hydrogen-depleted gas and the purge gas are combusted, usually in a combustion turbine, to generate heat or power.  Lower purity hydrogen can therefore be used in the synthesis of the ammonia.

Patent CA-2360925-A1 (CA)
Inventor: SAVIN SILVIU
IPC: H04B10/294
Filed: 2000-01-05
Abstract: An optical amplifier has a gain profile which is substantially flat and independent, over a wide range, of the pump power, power of the input signals, and the number of input signals. The amplifier utilizes an optical resonator having a gain medium whose gain broadening behaves inhomogeneously by pumping the gain medium at at least one wavelength in at least one absorption tail of the gain medium.  The resonator is a ring resonator that preferably includes an erbium-doped fiber. Codopants may be added to the fiber to enhance the inhomogeneous broadening effect. A method of gain flattening introduces a pump signal into a gain medium. The pump signal has a wavelength in the tail of the absorption profile of the gain medium. A  plurality of optical signals at different wavelengths are introduced into the gain medium. Stimulated emission within the gain medium clamps the gain of the gain medium.

Inventor: DE WINTER EDWIN JOHANNUS GERAR
IPC: A23B5/015
Filed: 2000-03-24
Abstract: The invention relates to a method for treating products, which may contain cellular material of eukaryotic and/or prokaryotic origin and in particular micro-organisms, by bringing the product in device comprising two electrodes connected to an electronic circuit such that in said device and in said product a pulsating electrical field is created, characterised by the rise time of each imposed voltage pulse which is less than the electronic relaxation time of the product. Preferably the rising edge of each cycle starts within the relaxation time of the product and even more preferably each electrical field pulse has a duration shorter than the relaxation time of the product. Dependent on the type of product and the types of micro-organisms contained in the product, the maximum fieldstrength of each pulse, the repetition frequency and the number of cycles in the treatment are selected such that the target micro-organisms and/or spores are functionally inactivated leading to a shelf stable, microbiologically safe product.

Title: Apparatus and method for protecting a load from fluctuations in supply voltage
Inventor: HA CHI THUONG
IPC: H02H3/00
Filed: 2001-12-18
Abstract: A power switch connecting a load to an ac source is turned off when the RMS value of the supply voltage is outside selected limits and is turned back on when the RMS voltage returns to within the limits. Adaptive hysteresis is applied to the switch controller to eliminate chattering of the power switch when the voltage fluctuates around the selected limits. To this end, the selected limits are repetitively, incrementally narrowed each time the power switch is turned off and back on a selected number of times, such as twice, within a selected time interval. The RMS voltage is rapidly determined from samples gathered over 1/4 cycle so that the voltages in a three phase system can be successively repetitively calculated.  Phase loss is rapidly determined by checking for the leading edge of a square wave generated from the supply voltage wave form.
