Patent CA-2260455-A1 (CA)
Inventor: BARKESHLI SINA
IPC: H01Q5/45
Filed: 1999-01-27
Abstract: An antenna system having a front reflector and a rear reflector arranged in tandem, a front feed for illuminating the front reflector, and a rear feed for illuminating the rear reflector. Each of the reflectors has a generally dish-shaped configuration, and the feeds are located in positions offset from axes of the respective reflectors. The front reflector is reflective to a first radiation, while being substantially transparent to a second radiation except for a fraction of the power of the second radiation. The fractional part of the second radiation is reflected from the first reflector as an interfering beam, the interfering beam being scanned away from a coverage region of a beam of the first radiation by an offset between the feeds. The radiations may differ in polarization or in frequency. There may be a complete shading of the rear reflector by the front reflector from the radiation of the rear feed to produce uniform illumination of the rear reflector for greater accuracy in a formation of a beam from the rear reflector. Six degrees of freedom in positioning and orientation of the reflectors and their feeds provides maximum design flexibility for obtaining a compact antenna.

Patent CA-2275036-A1 (CA)
Inventor: DEYOUNG THOMAS W
IPC: G01N35/10
Filed: 1999-06-15
Abstract: An analytical instrument has a sample handler for inputting racks of containers, including various types and sizes of test tubes, both capped and uncapped, and inserts, into the instrument. The sample handler has an infeed, an outfeed and a cross-feed between the infeed and outfeed. The infeed and outfeed advance the racks of containers using walking beam mechanisms which lift the racks by tabs on the right and left sides of the rack, which are positioned at a substantially identical height. Racks input into the infeed are transferred by the walking beam mechanism to a track on the cross-feed. They are then pushed, by a transport subassembly having a platform with pivotable pusher fingers to cam the rack and to push it in only one direction, from behind the infeed to a fixed position behind the outfeed. During this transport, the cross-feed maintains the racks in a vertical position and the racks pass a bar code reader to read bar code labels on the racks and test tubes and then under an ultrasonic liquid level sensor that takes multiple readings to determine the types of the containers, whether the containers have caps that need to be removed, and, if the containers are uncapped, the liquid level of the samples in the containers. The pusher fingers hold the rack in the fixed position behind the outfeed to allow a robotic arm on the instrument to retrieve the containers. After the removal of the containers, a tray on the outfeed walking beam mechanism is used to remove the rack from the cross-feed and transfer it to the outfeed. The outfeed has detents for holding the racks by the tabs in fixed positions for the insertion of containers into an available position on a rack. The cross-feed may be transformed into a bidirectional shuttle to transport containers between a laboratory automation transport line and the instrument. The sample handler may also have a stat shuttle in which test tubes, inserts, and other containers, including reagent and diluent packages, may be fed.

Patent CA-2278262-A1 (CA)
Title: Hingeless, parallel storing, sectional aperture covering
Inventor: CRAIG CLARK
IPC: E06B9/06
Filed: 1999-07-20
Abstract: An aperture covering including track-guided interconnectable panels that are compactly stored in a box containing weight counterbalancing mechanisms, such as a compressed spring. When the panels are stacked in the box and removed one at a time, the first panel is removed from the storage container and enters the track. As the first panel moves through the track, it interlocks with the second panel and forces the second panel out of the storage container and into the track. Interlocking and removal of the panels continues until all of the panels are removed or the first panel reaches the end of the track. Weight counterbalancing can be assisted by track-contained toothed belts or cable and ball drive mechanisms. The resulting aperture covering requires minimal storage space for the open aperture position, while minimizing exposure to potentially hazardous counterbalancing mechanisms.

Title: Apparatus and method for packet switching with supertrunking
Inventor: CHAPMAN ALAN STANLEY JOHN
IPC: H04L12/56
Filed: 1999-10-13
Abstract: A packet routing system is disclosed that allows for efficient transfers of IP streams from router to router with use of supertrunking. The router that receives an IP stream set for transmission on a supertrunk, individually inputs the IP packets, determines the logical output port corresponding to the IP stream, assigns each IP packet to a physical output port within the logical output port with use of a load balancing function, encapsulates each IP packet within a supertrunk header comprising an IP stream identifier and a packet sequence identifier and an IP header that has identical source and destination addresses as the original IP packet, and forwards the encapsulated packets to the receiving router via a plurality of physical links. The router that receives the encapsulated IP packets then re-orders the packets into the proper order with use of a sorting algorithm, removes the IP and supertrunk headers, and outputs an IP stream similar to that input to the original router.
