Patent CA-2312502-A1 (CA)
Inventor: BUCHOLTZ BRIAN CHARLES
IPC: F16F7/09
Filed: 2000-06-26
Abstract: A double acting shock isolator that includes a cylindrical housing having a radially expanded chamber therein. The housing is closed at one end and open at the other end and a connector is mounted at the closed end. A stack of friction rings are mounted in a preloaded condition between the ends of the expanded chamber and a rod passes into the open end of the housing and through the stack. A pair of spaced apart raised flanges are mounted upon the rod that engages either end of the stack. A second connector is mounted upon the distal end of the rod outside of the housing so that the stack of friction rings is further compressed uniformly when either a tensile force or a compressive force is applied to the connectors.

Title: Instrument or treatment instrument with laser sighting
Inventor: HOLLANDER MILTON BERNARD
IPC: G02B23/00
Filed: 2000-07-04
Abstract: A laser sighting device, for use in conjunction with measuring and treatment instruments, such as pyrometers, has means for generating at least one primary laser beam, of relatively greater intensity, to be directed at a target surface so as to illuminate a small area thereof, for example a central spot of the area.  The device has means for, from time to time, sub-dividing the at least one laser beam into a greater number of secondary beams of lesser intensity directed towards the target area for the purpose of creating on the target surface at least a number of spots some of which are spaced outwardly of the central area, to define a zone for investigation with the instrument. The secondary beams are of lesser intensity than the primary beam and vary in number, and the arrangement is such that the means for sub-dividing the primary beam operate at timed intervals so that the target area is illuminated alternately at the central spot, and thereafter by the secondary beam spots, for defining the zone under investigation. The secondary beam spots serve to define one or more patterns, such as a closed loop, on the target area. Secondary beams include a central spot beam. As the result of subdividing of the primary beam is to lessen the intensity of the spots formed by the secondary beams, the primary beam serves to give the user of the instrument a clear visual indication of a point of the target area, for aiming purposes, whereafter the spots of the secondary beams serve to indicate to the user the specific area of the target which is under investigation.

Patent CA-2321725-A1 (CA)
Inventor: TOLPUTT STEPHEN ADRIAN
IPC: G01D5/24
Filed: 1999-03-01
Abstract: An arrangement for detecting/inspecting items (13), for example, pills, comprises a four-sided transducer (22) which by means of arrangements of capacitor plates (10, 11; 23-26) on or forming its side surfaces provides, in use, four (spacially) intersecting electric fields. When items fall through the electric fields of the transducer they cause a change in the voltage induced on a capacitor plate of each of the four capacitors, and respective signal processing means for the four capacitors have their D.C. voltage outputs combined and analysed by a microprocessor (40) or the like to determine if the item detected has sufficient material to be classed as acceptable. The arrangement is such that inspection is largely unaffected by the orientation of the item as it passes through the transducer. In an alternative embodiment, two intersecting electric fields are provided and pulse length and height relating to the passage of the item are analysed.

Title: Multi-carrier/multi-sector channel pooling in a wireless communication system base station
Inventor: RUBIN HARVEY
IPC: H04J1/00
Filed: 2000-10-12
Abstract: A wireless communication system base station includes a number of channel unit boards, each including multiple channel elements for providing processing operations for signals assigned to multiple carriers of the system. A given channel unit board includes a multiplexer which is operative to implement multi-carrier/multi-sector channel pooling by assigning a given one of the channel elements of that board to any one of the multiple carriers of the system. For example, the multiplexer in the given channel board may be operative to connect the channel elements of that board to I/Q signal buses associated with different system carriers. The I/Q signal bus for each of the carriers is then combined on the given board with corresponding signals from other boards. The invention allows each of N channel elements of the given channel unit board to be assigned to a particular one of up to N carriers of the system, thereby providing substantially improved flexibility in terms of system configuration.

Title: Method and device for mixing light in a polarization dependent manner
Inventor: DUCELLIER THOMAS
IPC: G02F1/31
Filed: 2000-11-22
Abstract: This invention relates to optical devices that use the state of polarization (SOP) of the orthogonally polarized sub-beams of a composite optical signal to select pathways through a set of birefringent components. The SOP of the sub-beams is changed to affect the resulting path through the birefringent components and in this manner the sub-beams can be separated, mixed with other sub-beams and or recombined with the original sub-beams to form new signals at different locations (ports) of the optical devices presented. The use of the basic system to built more complicated systems results in a closed four port optical circulator based on birefringent crystals. The basic system is also used to construct an optical switch and an optical add/drop switch based on birefringent crystals.

Dans un autre mode de réalisation, un circuit comporte un premier chemin de circuit comprenant un premier élément inductif couplé à une première lampe et un second circuit comprenant un second élément inductif couplé à une seconde lampe. Les premier et second éléments inductifs sont couplés de manière inductive, de sorte qu'ils suppriment efficacement le flux généré alors que les première et seconde lampes sont excitées. Lorsqu'une des lampes est enlevée, le flux n'est plus supprimé, de sorte qu'une tension disruptive soit générée au niveau des bornes de lampe desquelles la lampe a été enlevée.

Title: Tether latch for securing a child vehicle seat to an anchorage
Inventor: BARRETT ROBERT C
IPC: B60R22/12
Filed: 2001-03-23
Abstract: The present invention relates to a latch for coupling tether straps attached to child vehicle seats to anchorages provided on the vehicle, e.g., anchorages provided on the package shelf of the vehicle or anchorages located at the crease of the seat bottom and seat back. The latch provides advantages over the common "J" hook currently in use, including a push button remote from the hook of the latch.  In addition, the latch may include an opening for attachment of the tether strap.  In one preferred embodiment, the latch further includes a plate which is coupled to a strap length adjuster, the plate and adjuster being pivotally connected to permit side-to-side rotation of the adjuster relative to the latch to prevent bunching or twisting of the strap which can cause the belt to loose its ability to uniformly distribute a load across its width. Furthermore, the adjuster itself may be coupled to a plate which is pivotably coupled to the plate attached to the latch, to thereby permit movement of the strap about two perpendicular axes.

Patent CA-2345806-A1 (CA)
Inventor: KOPRIVICA MILOSH
IPC: H04B1/715
Filed: 2001-05-03
Abstract: A method of dynamic channel allocation in a frequency hopping communications system is disclosed providing improved efficiency and reliability. During the course of communications between a plurality of transceivers over a frequency hopping wireless communications link, a transceiver begins evaluating the performance of each channel in the hop sequence, starting at a fixed point in the sequence. The transceiver proceeds sequentially through the hop sequence, until a channel fails to satisfy a predetermined quality criterion. A channel which fails to satisfy the quality criterion is considered bad, and substituted with a replacement channel from a set of available channels via an unacknowledged channel replacement command. The channel evaluation process is subsequently reinitiated beginning anew at the fixed point in the hop sequence, thus operating to maintain a set of consecutive good channels.
