Patent CA-2116875-C (CA)
Inventor: KEYWORTH BARRIE PETER
IPC: G02B1/04
Filed: 1994-03-01
Granted: 2002-10-22
Abstract: A method of forming an optical element on the surface of a substrate by ejecting a curable light guide forming liquid from a nozzle onto the substrate and curing the curable light guide forming liquid. A waveguide may be formed by moving the nozzle in a linear pattern over the surface of the substrate during ejection of the liquid from the nozzle. Curing the liquid may include exposing the liquid to ultraviolet radiation, and the radiation may be applied to only a small portion of the liquid. A multilayered waveguide may be formed by ejecting a further light guide forming liquid onto the first and curing it. A core and cladding may be formed simultaneously by ejecting core forming liquid from an inner tube and cladding forming liquid from an annulus about the inner tube. The waveguide may be formed in a groove, and a splitter may be formed by branching a second waveguide from a first, or by laying out two parallel waveguides and connecting them. Apparatus for forming a light guide on a substrate includes an xy movable support for the substrate, and a container having a nozzle, the nozzle being movable in relation to the substrate, and a dispenser to regulate dispensing of liquid from the container. Liquid curing radiation may be provided through a source of UV light. The nozzle may be formed of a first central tube and a second outer tube disposed about the first central tube to form an annulus between them. A microlens may be formed by holding the nozzle stationary during dispensing.

Abstract: The invention pertains to a method of site-specific mutagenesis of DNA. In this method, a parental DNA containing a non-essential, unique restriction site is used to generate progeny DNA containing the desired mutation beta lacking the restriction site.      The non-mutant parental DNA and the mutant progeny DNA are treated with any enzyme that cleaves at the restriction site to cleave the parental DNA; leaving the mutant DNA uncleaved. Mutant progeny DNA is selected by transforming cells with the enzyme-treated DNA under conditions in which the cells are transformed with uncleaved DNA at a higher efficiency than with- cleaved DNA so that the majority of transformants carry the mutant DNA.

Abstract: An exhaust gas recirculation system for a compression ignition engine and a method of controlling exhaust gas recirculation in compression ignition engines are disclosed. The method and apparatus are adapted to the control of exhaust gas recirculation in diesel and/or multifuel (e.g. diesel and natural gas) engines. The apparatus includes a first pressure sensor for sensing an absolute gas pressure in the intake manifold of the engine, a second pressure sensor for sensing an absolute gas pressure in the exhaust manifold of the engine, an engine speed sensor for detecting engine RPM, a fuelling rate sensor for detecting the commanded fuelling rate for the engine, a temperature sensor for detecting the temperature of intake air in the intake manifold, a conduit for directing exhaust gas from the exhaust manifold to the intake manifold, an electronically actuated mechanical valve in the conduit for controlling the flow of exhaust gas and an electronic controller for analyzing signals from the sensors and outputting control signals to an electric stepper motor which controls the position of the valve. The advantages include accurate control of exhaust gas recirculation in real time, rapid response to changing combustion conditions which result in reduced pollution emission and higher fuel efficiency. A further advantage is a system which is readily retrofit to an existing compression ignition engine or included as a part of original equipment in new engines without engine redesign.

Title: Stereophonic acoustic echo cancellation using nonlinear transformations
Inventor: HALL JOSEPH LINDLEY II
IPC: H04M3/56
Filed: 1997-09-16
Granted: 2000-12-05
Abstract: A method and apparatus for estimating individual impulse responses for a stereophonic communication system, such as a teleconferencing system, which involves selectively reducing the correlation between the individual channel signals of the stereophonic system. Selective reduction of stereophonic source signal correlation advantageously results in the estimation of individual impulse responses of a receiving room of the stereophonic communication system. The selectively reduced-correlation source signals are provided to conventional adaptive filters and the receiving room loudspeakers. Automatic echo cancellation is performed in a conventional fashion, but on the selectively reduced-correlation source signals. Specifically, selective reduction of source signal correlation between two stereophonic channels of a teleconferencing system is achieved by introducing a small non-linearity into each channel in order to reduce the interchannel coherence. In accordance with certain illustrative embodiments of the present invention, each channel signal has added thereto a non-linear function of the channel signal itself, thereby reducing the interchannel coherence while preserving the quality of the signal. In one particular embodiment, the non-linear functioncomprises the half-wave rectifier.
