Patent CA-2207483-A1 (CA)
Inventor: TAIT GORDON A
IPC: A63B69/36
Filed: 1997-06-10
Abstract: A practice platform is provided for use by a golfer to practice swinging a club on different inclines. The practice platform has a deck pivotally mounted to a base. Unlike known prior practice golf platforms, the deck is intended to be pivoted to different inclines solely by the golfer's positioning himself upon the deck so that his weight causes the deck to pivot, without the use of a power drive mechanism. The platform includes a mechanism to hold the deck in the selected position, and also to facilitate positioning of the deck by restricting it from pivoting freely through its full range of motion in reaction to the golfer's weight. A valve is provided which can controlsimultaneously the pivoting of the deck in all directions.

Title: Azetidine, pyrrolidine and piperidine derivatives
Inventor: VAN NIEL MONIQUE BODIL
IPC: C07D521/00
Filed: 1996-11-13
Abstract: A class of substituted azetidine, pyrrolidine and piperidine derivatives, linked by a fluoro-substituted alkylene chain to a fused bicyclic heteroaromatic moiety such as indolyl, are selective agonists of 5-HT1-like receptors, being potent agonists of the human 5-HT1D.alpha. receptor subtype whilst possessing at least a 10-fold selective affinity for the 5-HT1D.alpha.  receptor subtype relative to the 5-HT1D.beta. subtype; they are therefore useful in the treatment and/or prevention of clinical conditions, in particular migraine and associated disorders, for which a subtype-selective agonist of 5-HT1D receptors is indicated, whilst eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT1D receptor agonists.
Patent CA-2238552-A1 (CA)
Inventor: CHAN DAVID CHI-YIN
IPC: H04L12/56
Filed: 1996-11-22
Abstract: A method for transmitting packetized data in a cellular communication system uses a dynamic channel assignment scheme. In this aspect of the invention a data control channel is used in addition to the data traffic channel. The mobile end system uses the data control channel to send a request for assignment of a channel for transmission of data - such as a particular frequency/time-slot in a TDMA system. The network responds with the identification of a particular channel that may be used for a particular time period to transmit data. In this aspect of the invention there is no dedicated channel that is used for data transmission. Rather, the network determines a channel that will be free for the specified time period and assigns it for data transmission.

IPC: H04L25/06
Filed: 1998-07-28
Abstract: To reduce the DC-offset in bursts (B1, B2) of a digital signal (S1), some samples of one of the digital bursts (B1) which have no predetermined value are averaged by an averager (AV) resulting in a correction value (CV). Meanwhile the samples of this digital burst (B1) are temporarily stored in a memory (MEM1). The DC-offset correction value (CV) calculated by the averager (AV) is then subtracted from the samples of the digital bursts (B1, B2). In this way, he dynamic range of the samples is reduced significantly.

Patent CA-2248662-A1 (CA)
Inventor: JIANG YIMIN
IPC: H02M3/335
Filed: 1998-09-24
Abstract: A multiple output dc to dc converter is described that has multiple regulated output voltages. This is achieved by using a common subcircuit in conjunction with multiple input subcircuits to power multiple output circuits. The common subcircuit is used with an input subcircuit to form a converter input circuit which with a corresponding output circuit produces an output voltage. Any number of input subcircuits can be used with the common subcircuit to produce a corresponding amount of output voltages. The multiple output dc to dc converter described produces output voltage of the same quality as using parallel converters but with a cost and complexity similar to that of using inferior secondary side switches for auxiliary outputs.
