Patent CA-2389937-A1 (CA)
Title: Multi-pass configurations
Inventor: LAMONT MICHAEL R E
IPC: G02B26/00
Filed: 2002-06-10
Abstract: A method and device is disclosed for relaying a narrow diameter collimated optical beam carrying optical communication signal channels between a multilayer interference filters and another reflective surface avoiding signal loss by routing the optical beam to compensate for beam broadening caused by the multilayer interference filter. The method and device are particularly applicable to dispersion compensating filters, especially those wherein one filter is tunable, in that a controllable amount of dispersion is introduced to offset or compensate dispersion. Preferably one of the filters is a tunable periodic device in the form of a multi-cavity etalon structure. In a preferred embodiment of the filters can be designed to provide various controllable but different constant amounts of dispersion.

Abstract: A hand-held pressurized product dispenser (10) that includes a container (12 ) with a hand-engageable body portion, a valve mechanism (14) at the top of th e container that is movable with respect to the container to cause pressurized  discharge of the product, and a valve actuation lever (20) that is connected  to the valve mechanism (14) and extends along the container body such that a  larger displacement of the end of the lever causes a controlled, relatively smaller displacement of the valve mechanism, permitting adjustable "throttle d" delivery of the product. Also disclosed are: a product delivery member (60) that is attached to the top of container and has a product holding structure  (68) that is positioned with respect to the valve mechanism to receive produ ct and to hold the product in position for application; cam members (102, 106,fig. 11) are oriented to cause the valve actuating lever (108, fig. 11) to move downward as it is moved toward the container body: and a movable stop member (114, 124 figs. 12 and 13) that is carried on the container and faces  the hand-engageable portion (108) so as to limit travel of the hand-engageab le portion toward the container.

Title: Drainage system and method for artificial grass using spacing grid
Inventor: PREVOST JEAN
IPC: E01C13/08
Filed: 2002-07-12
Abstract: A drainage system is provided for a synthetic grass turf assembly having a flexible and water permeable sheet backing for installation on a supporting soil substrate to provide a game playing surface. The draining system of the present invention prevents water from accumulating on the turf surface, which could cause the top-dressing layer to "float" and be moved by inundation. The draining system of the present invention includes a spacing grid disposed between the backing of the turf. The spacing grid is structured to permit water not only to be drained vertically through the spacing grid, but also to be drained horizontally through the spacing grid to the edges of the field. The spacing grid is made from one or more types of geotextile or plastics material with an adequate flexibility to improve the impact absorption capabilities and resilience of the synthetic grass turf assembly.

Patent CA-2398586-A1 (CA)
Inventor: NELSON THOMAS D
IPC: A01M1/20
Filed: 2001-01-22
Abstract: The present invention relates to a bait station comprising a base, a reservoir, a cover, and a latch. The base may be used in two different orientations and includes a first section and a second section. The first section has climbing assisting members and a cavity with a reservoir receiving area, and the second section has side climbing assisting members. The climbing assisting members and side climbing assisting members of the base provide a textured surface that enables insects to crawl into and out of the bait station more easily. The reservoir contains poisonous bait and may be placed in two different positions within the reservoir receiving area to accommodate the two different orientations in which the base may be used. The reservoir includes tapered sides with climbing assisting members. The climbing assisting members provide a textured surface that enables insects to crawl into and out of the reservoir more easily. The reservoir also includes an aperture proximate a corner of the reservoir, which provides an entrance into and out of the reservoir and reduces the rate of evaporation of the poisonous bait. The tapered sides of the reservoir also reduce the rate of evaporation of liquid bait because as the volume of the bait decreases, the surface area of the bait exposed to air flowing in and out of the reservoir is also decreased. Finally, the cover is configured and arranged to fit over the base, and the latch secures the cover to the base.

Title: Automated method and system for selecting and procuring electronic components used in circuit and chip designs
Inventor: PLYMALE JAMES M
IPC: G06F17/50
Filed: 2001-02-26
Abstract: A method and system for obtaining information about electronic components, managing that information, and/or purchasing and procuring electronic components comprises a remote parts database connected to a distributed electronic network, such as the Internet. The remote parts database stores a plurality of dynamic parts for use in a schematic program run on a user workstation. When the user connects to the remote parts database, a listing of available dynamic parts are displayed on the user's workstation. The user selects dynamic parts for inclusion into an application (such as a schematic program) running on the user's workstation. The dynamic parts are downloaded to the user workstation and a local database. The downloaded information includes data regarding the parts functionality plus component data items such as supplier or distributor information, timing information, application notes, and a link (e.g., URL) to either the remote parts database or a remote supplier or manufacturer database.  As dynamic parts are selected for use in a design, their information may be forwarded to a parts approval process for qualification with the designer's organization. From a design in the schematic program having multiple dynamic parts, a bill of materials may be automatically generated based on the locally stored component data items, including the supplier/distributor information.

Title: Mobile communication control method, cellular system, mobile station, base station, and base station control apparatus
Inventor: HAMABE KOJIRO
IPC: H04W36/18
Filed: 2001-06-18
Abstract: When a mobile station makes connections with a plurality of base stations during hand over, the number of the base stations that perform transmission is reduced and a base station that exhibits the best reception quality is caused to perform transmission, thereby reducing the downstream interference to increase the line capacity. In the mobile station, a reception monitor (406) periodically measures pilot signals transmitted from base stations. Upon occurrence of a soft hand over condition, a speed estimating device (407) estimates the moving speed of the local station at a predetermined time interval on the basis of the reception electric field intensity of the pilot signals. A control unit (408) changes, in accordance with the estimated moving speed, both the time length for which to measure the pilot signals transmitted from the base stations and an internal threshold value for selecting a base station for transmission during the hand over. In that case, when the moving speed is low, the time length for measuring the pilot signals is shortened and the internal threshold value is reduced. When the moving speed is high, the time length for measuring the pilot signals is elongated and the internal threshold value is increased.
