Patent CA-2512849-A1 (CA)
Inventor: GLASER BRYON
IPC: E04H15/44
Filed: 2005-07-21
Abstract: A collapsible free-standing frame structure includes N bowable resilient legs, where N is an integer greater than one, a multi-hinge, and a leg restraint. The multi-hinge includes a hinge body and N leg interconnectors for interconnecting the legs to the hinge body.  The leg interconnectors are pivotally mounted to the hinge body for limited pivotal motion between closed positions, in which the interconnected legs are clustered around a central axis which extends through the hinge body, and open positions, in which the interconnected legs extend radially relative to the central axis. A pivot stop prevents the leg interconnectors from pivoting beyond the open positions. To erect the frame structure, the leg interconnectors are pivoted to their open positions, the interconnected legs are bowed against the pivot stop, and the distal ends of the bowed legs are attached to a leg restraint which maintains the legs in the bowed position.

Title: Frequency division multiplexing of multiple data streams in a wireless multi-carrier communication system
Inventor: KRISHNAMOORTHI RAGHURAMAN
IPC: H04L5/02
Filed: 2004-10-21
Abstract: Techniques for multiplexing multiple data streams using frequency division multiplexing (FDM) in an OFDM system are described. M disjoint "interlaces"  are formed with U usable subbands. Each interlace is a different set of S  subbands, where . The subbands for each interlace are interlaced with the subbands for each of the other interlaces. M slots may be defined for each symbol period and assigned slot indices 1 through M. The slot indices may be mapped to interlaces such that (1) frequency diversity is achieved for each slot index and (2) the interlaces used for pilot transmission have varying distances to the interlaces used for each slot index, which improves channel estimation performance. Each data stream may be processed as data packets of a fixed size, and different numbers of slots may be used for each data packet depending on the coding and modulation scheme used for the data packet.

Inventor: KNOTT ERROL P
IPC: B65G15/32
Filed: 2006-06-06
Abstract: A modular plastic conveyor belt having an A-shaped edge portion in belt edge modules along each belt row for tight collapse of the belt at the inside of a turn. The A-shaped region comprises two alternating series of laterally spaced links, each extending from opposite ends of the edge module. Each of the first series of links forms an acute angle measured clockwise from the direction of belt travel. Each of the second series of links forms an acute angle measured counterclockwise from the direction of belt travel.  The angles decrease monotonically with distance inward of the first side of the belt edge. Laterally extending webs join the ends of consecutive converging links along an end of the module. The lateral extent of the webs increases monotonically inward from a first side edge of the belt. A cross bars extends between each pair of web joined links. First cross bars between links joined at a first end of the module lie along a first imaginary line;  second cross bars between links joined at an opposite second end of the module lie along a second imaginary line. The two imaginary lines converge inward from the first side edge of the belt to form deeper gaps toward the first side edge for tighter belt collapse at the inside of a turn.

Title: Modulators of peripheral 5-ht receptors
Inventor: BRUDELI BJARNE
IPC: C07D405/12
Filed: 2004-12-23
Abstract: Novel modulators of 5-HT4 receptors have been developed which have a selectivity for peripheral receptors rather than those of the central nervous systems. Theses include novel derivatives of known modulators as well as entirely novel entities. Surprisingly, the derivatised compounds of the known modulators maintain a high binding affinity to 5-HT4 receptors, despite the presence of an acidic moiety at the end of an optional chain. The entirely novel entities also exhibit good binding affinity to 5-HT4 receptors. All of the compounds of the invention have a common motif which includes a basic nitrogen moiety and an acidic moiety. The compounds of the invention, due at least in part to their high ionisation potential at physiological pH, have the unique properties of selectively for peripheral 5HT4 receptors over those of the CNS, good binding affinity, and selectively of 5HT4 receptors over other serotonin receptors.
