Patent CA-2425667-A1 (CA)
Inventor: OHNSTEIN THOMAS RAYMOND
IPC: G02B7/00
Filed: 2001-10-11
Abstract: L'invention concerne un système de micro-positionnement pour positionner correctement un élément optique par rapport à un dispositif optique tel qu'une diode laser, un laser à cavité verticale et émission par la surface (VCSEL), un photodétecteur à cavité résonante (RCPD) ou d'autres types de dispositifs optiques. Le système de micro-positionnement est conçu pour déplacer l'élément optique indépendamment dans les deux directions X et Y. Cet élément optique comporte de préférence au moins deux zones à caractéristiques optiques différentes. Lorsqu'il est en fonctionnement, l'élément optique est déplacé de manière sélective de sorte qu'un faisceau lumineux coupe une zone sélectionnée de celui-ci. Vu qu'il est doté de caractéristiques optiques différentes selon ses zones, l'élément optique donne un résultat optique différent à mesure que le faisceau lumineux est déplacé sur lesdites zones, ce qui est utile dans un certain nombre d'applications comprenant, par exemple, le réalignement optique, la commutation optique y compris le multiplexage spatial (SDM), le multiplexage en longueur d'onde (WDM) et le multiplexage en polarisation (PDM).

Abstract: A circuit for processing radio frequency signals. The circuit includes a substrate where the circuit can be placed. The substrate can be a meta material and can incorporate at least one dielectric layer (100). A directional coupler (106) and at least one ground (112) can be coupled to the substrate. The dielectric layer can include a first region (102) with a first set of substrate properties and a second region (104) with a second set of substrate properties. The substrate properties can include a permittivity and a permeability. A substantial portion of the directional coupler (106) can be coupled to the second region (104). The permittivity and/or permeability of the second region (104) can be higher than the permittivity and/or permeability of the first region (102). The increased permittivities and/or permeabilities can reduce a size of the directional coupler (106) and effect a charge in a variety of electrical characteristics associated with the directional coupler (106).

Title: Resistance to acetohydroxyacid synthase-inhibiting herbicides
Inventor: CROUGHAN TIMOTHY P
IPC: A01H5/10
Filed: 2001-05-09
Abstract: Nucleotide sequences are disclosed that may be used to impart herbicide resistance to green plants. The sources of novel resistance were originally isolated in mutant rice plants. The sequences impart pre-emergence resistance, post-emergence resistance, or both pre-emergence resistance and post-emergence resistance to multiple herbicides. To date, resistance has been demonstrated against at least the following herbicides: imazethapyr, imazapic, imazapyr, imazamox, sulfometuron methyl, imazaquin, chlorimuron ethyl, metsulfuron methyl, rimsulfuron, thifensulfuron methyl, pyrithiobac sodium, tribenuron methyl, and nicosulfuron. Green plants transformed with these sequences are resistant to these herbicides and to derivatives of these herbicides, and to at least some of the other herbicides that normally inhibit acetohydroxyacid synthase (AHAS), particularly imidazolinone and sulfonylurea herbicides.

Abstract: A tubular prosthesis, which may be an endovascular prosthesis, is provided which includes a tubular member (12, 12A) (stent or stent/graft combination) and an outer covering (14) having portions sealed to the tubular member. The tubular member is impervious to a pre-determined fluid, particularly an occluding fluid, while the outer cover is pervious to the pre-determined fluid. In one aspect of the present invention, the implantation of the prosthesis allows for occluding fluid to weep from the prosthesis and into a sac of an aneurysm to cause occlusion thereof without introducing the occluding fluid into the blood stream. In this manner, a Type II failure of the prosthesis may be avoided. In other aspects of the invention, therapeuti c agents may be delivered and/or a seal may be formed about the prosthesis to prevent a Type I failure.

Title: Control of avalanche photodiodes bias voltage
Inventor: NICHOLLS PETER
IPC: H04B10/43
Filed: 2003-03-11
Abstract: An optical communications system uses forward error correction (FEC) to correct errors in signals carried by the system. Optical signals on the system are dropped at nodes and converted to electrical signals by avalanche photodiodes (APDs) at the node receivers. A FEC chip operates on the electrical signal to correct errors. The error rate is used to control the APD  bias voltage which affects signal noise and therefore, error rate. The errors in a predetermined interval are counted and a determination made as to whether the error rate is rising with time. The bias voltage is derived from the value of a counter whose count is incremented each interval. If the error rate is rising, the counting direction is changed.

Abstract: A system and method for applying brine solution to food pieces, such as pota to chips, allows application of brine solution to a continuous stream of food pieces in a brine bath, while maintaining a continuously refreshed supply of brine solution in the brine bath, but without requiring that the used brine be discharged as effluent. Food pieces are washed in a water bath and then deposited, with an amount of surface water carried on the washed slices, int o a brine bath tank. The brine bath tank has a predetermined volume of brine solution at a predetermined concentration of brining substance in the solution. The food pieces are marinated in the brine bath so as to thoroughl y wet the pieces and are then removed from the brine bath tank with an amount of surface solution carried on the slices. The amount of surface solution carri ed on the marinated slices is greater than the amount of surface water carried on the washed, pre-marinated slices. Brine solution and/or salts are continuous ly added to the brine bath tank to maintain a specified volume and concentratio n of brine solution within the brine bath tank. The amount of brine solution that is removed from the brine bath tank is about equal to the amount of fre sh brine solution and/or salts that are added to the tank, so that the entire volume of brine solution within the brine bath tank is replaced after processing a predetermined amount of food pieces through the brine bath tank . A microbicide may be added to the brine bath tank to prevent microbial growt h within the tank, and the brine solution may be filtered to remove filterable contaminants therefrom.
