Patent CA-2252200-A1 (CA)
Title: Rebar support system
Inventor: VERELLI ANGELO
IPC: E04C5/16
Filed: 1998-11-09
Abstract: This rebar chair has a body with four legs between which there are defined two intersecting passages for simultaneously receiving the intersecting portions of two rebars normal to each other. The rebars are suspended by a fastening wire or supported by an auxiliary chair below said body. The legs forming one of the passages have a uniform spacing and are adapted to closely straddle the rebar extending through the same. The chair is positively located and stabilized by the intersecting rebars. A saddle is formed on the top of the body for simultaneously supporting a third rebar. The spacing between the faces of the legs forming a first passage is uniform from the body to the free ends of the legs while the spacing between the faces of the legs forming the other right angle passage increases from the body to the free ends of the legs in such a manner that depending on the orientation of the chair with respect to the rebars the same can be positioned at two adjusted distances from the bottom of the concrete form.      The legs of the second passage flare downwardly so that their spacing progressively increases from the body to the free ends from a spacing smaller than to a spacing greater than the uniform spacing between the legs of the first passage.

Patent CA-2254407-A1 (CA)
Title: Method and apparatus for a flexible access rate common-memory packet switch
Inventor: BESHAI MAGED E
IPC: H04L12/56
Filed: 1998-11-17
Abstract: A method of controlling asymmetrical port access in a common-memory (CM) multi-port data packet switch and a high-capacity flexible access rate CM data packet switch are described. The method involves providing a common-memory- access control table which defines a unique contiguous band of CM access time slots allocated to each port of the packet switch. Each access time slot is identified by a time slot identifier. Time slot identifiers are generated at a regular interval. The time slot identifiers are generated so that CM access time for each port is substantially equally spaced to minimize delay fitter. The packet switch may have an equal number of input and output ports, or more output ports than input ports. In the high-capacity CM packet switch, several CM switch modules are interlinked by middle buffers in a folded configuration to provide a packet switch having Terabit output capacity. The advantage is a packet switch architecture which supports flexible access rates to eliminate idle switch capacity, the CM access time slots being substantially equally spaced apart to reduce packet transfer delay fitter.

Abstract: A method of estimating channel impulse response in a signal transmitted over a channel in a communication system is described. The channel estimator obtains a priori knowledge about the transmitted signal and then use the transmitted signal and the a priori knowledge to choose an estimate of channel impulse response which minimises the expected distance between the transmitted signal and a reconstructed signal. The expected distance that is minimised is a cost function;  represented by E{¦¦r-Bh¦¦2r)..  By using soft decision feedback, the invention minimises erroneous decision feedback which can cause error propagation. The decision are usually in the form of log likelihood ratios (LLR).
