Title: Gaming machine with variable probability of obtaining bonus game payouts
Inventor: GURA DAMON E
IPC: G07F17/32
Filed: 2000-06-29
Abstract: A gaming machine includes a basic game and a bonus game. The basic game is controlled by a processor in response to a wager amount and includes a plurality of different start-bonus outcomes. The bonus game is activated by the start-bonus outcomes which cause the processor to shift operation from the basic game to the bonus game. The bonus game is capable of providing a plurality of bonus payouts. In accordance with one feature of the gaming machine, a probability of winning certain ones of the bonus payouts varies in response to the different start-bonus outcomes that activate the bonus game. In accordance with another feature of the gaming machine, the bonus game includes a video-type display controlled by the processor and displaying a plurality of player-selectable elements, at least one of which represents a winning bonus game outcome. The player-selectable elements are successively selected by a player until the winning element is selected. In response to the selection of the winning element, the bonus game awards the player a bonus payout. The value of the bonus payout successively decreases in response to the player successively selecting the non-winning elements prior to selecting the winning element.
Patent CA-2313704-A1 (CA)
Inventor: HALL STEPHEN G
IPC: A61P37/04
Filed: 1998-12-07
Abstract: Recombinant nodavirus related compositions are disclosed. These compositions include chimeric proteins in which a nodavirus capsid protein is present together with a heterologous peptide segment. The heterologous peptide includes at least one cell-specific targeting sequence, such as a B cell epitope, a T cell epitope, or a sequence specific for another cell type, such as a hepatocyte. The chimeric proteins can be assembled to form chimeric virus-like particles. The chimeric virus-like particles are useful in therapeutic applications, such as vaccines and gene-delivery vectors, and in diagnostic applications, such as kits for the testing of body tissue or fluid samples. Methods for the use of recombinant nodavirus related compositions in therapeutic and diagnostic applications are also described.

Patent CA-2316260-A1 (CA)
Inventor: WHEATLEY CHARLES E III
IPC: H04B7/26
Filed: 1999-01-15
Abstract: In the present invention, the slave base station (64) attains synchronization with the reference base station (62) through messages (504) transmitted from and received by a mobile station (60) either in the soft handoff region between the reference base station (62) and the slave base station (64) or within a range which allows the mobile station (60) to communicate with the slave base station (64). When the mobile station (62) is not in communication with both the reference base station and the slave base station (62), then the round trip delay between the mobile station and the reference base station is measured by the reference base station (62). The reference base station (62) communicates the PN code used by the mobile station over the reverse link to the slave base station. The slave base station (64) acquires the signal (504) from the mobile station (60) and determines when the signal from the mobile station arrives. The slave base station (64) then makes and estimates as to the length of the delay between transmission of a signal from the mobile station (60) to the slave base station (64). Based upon these measurements and estimates, the slave base station (64) determines the error which is present in the slave base station system time.

Patent CA-2317446-A1 (CA)
Title: Method and device for configuring a link
Inventor: LUDWIG REINER
IPC: H04L12/28
Filed: 1999-01-11
Abstract: The invention relates to method and device for improving the link configuration speed of high-latency links, such as circuit switched links or satellite links, that use chatty protocols, which require sequential configuration phases, such as standard PPP in accordance with RfC 1661. In the initial link configuration phase, a standard LCP packet is sent out, followed by at least one masked packet that will be discarded silently by a peer operating in accordance with the standard protocol, but whose contents will be processed by a peer operating in accordance with the invention.      The initial standard LCP packet produces compatibility with the standard protocol, whereas the sending of masked packets containing configuration information (PAP, CHAP, ICPC, etc.) allows two peers operating in accordance with the invention to accomplish the configuration phases in parallel, such that a link can be configured and ready to transmit network level packets, such as 1P packets, much more quickly than with the standard protocol, such as PPP.

Title: Cigarette paper containing carbon fibers for improved ash cohesiveness
Inventor: HAMPL VLADIMIR JR
IPC: D21H13/50
Filed: 2000-10-11
Abstract: The present invention is directed to a method for improving the ash characteristics of a paper wrapper for a smoking article and for improving the ash characteristics of the smoking article itself.      Specifically, it has been unexpectedly discovered that the ash cohesiveness of a paper wrapper is noticeably improved when carbon fibers having an average length less than about 0.75 inches are incorporated into the paper in an amount up to about 60% by weight. Paper wrappers made with carbon fibers in accordance with the present invention have superior ash characteristics in comparison to paper wrappers incorporating only flax or other cellulosic fibers.      Further, the ash cohesiveness of the paper is improved without resulting in the decline in the quality of other ash characteristics.
