Title: Discriminating between stationary and non-stationary signals
Inventor: JANSSON KLAS FREDRIK JANIS
IPC: G10L19/012
Filed: 1994-10-19
Abstract: Signal frames containing background sounds in a mobile radio communication system are tested for stationarity. Consecutive measures .DELTA.En representing spectral changes in said signals from frame to frame are formed (50, 52, 54, 56, 58). From these measures a second measure (M) of the rate of spectral change are formed (60, 62). Finally it is determined whether this second measure (M) exceeds a predetermined stationarity limit .gamma.. If this is the case the signals are considered stationary.

Patent CA-2176266-A1 (CA)
Inventor: TYAGI SANJAY
IPC: C12Q1/68
Filed: 1996-05-10
Abstract: Unimolecular and bimolecular hybridization probes for the detection of nucleic acid target sequences comprise a target complement sequence, an affinity pair holding the probe in a closed conformation in the absence of target sequence, and either a label pair that interacts when the probe is in the closed conformation or, for certain unimolecular probes, a non-interactive label.  Hybridization of the target and target complement sequences shifts the probe to an open conformation.          The shift is detectable due to reduced interaction of the label pair or by detecting a signal from a non-interactive label.  Certain unimolecular probes can discriminate between target and non-target sequences differing by as little as one nucleotide.          Also, universal stems and kits useful for constructing said probes.  Also, assays utilizing said probes and kits for performing such assays.

Abstract: A number-theoretic based algorithm provides for secure receipt-free voting. A vote generating center generates a choice of votes for each voter or vote chooser. The votes are encrypted, shuffled, and conveyed to a vote chooser along with information regarding how the votes were shuffled without being intercepted enroute. The information is preferably sent along secure untappable channels. The method can incorporate validification of generation and shuffling of the votes using chameleon commitment and interactive proofs. The invention can be realized by current-generation personal computers with untappable channels and access to an electronic bulletin board.

Title: Apparatus and method for working a malleable endless web
Inventor: GUEORGUIEV ATANAS DOBREV
IPC: B21D11/20
Filed: 1996-07-11
Abstract: The quality of a part formed from an endless malleable web may be adversely affected by bowing and camber of the web while it is being worked.  To avoid this problem, the web is stabilised at a first and a second web stabilising station.  A bow sensor between these stations outputs to a controller which, in turn, outputs a control signal to a vertical adjustment motor associated with the first web stabilising station in order to eliminate bow.  Similarly, a camber sensor between the first and second stabilising stations outputs to the controller so that the controller may output a control signal to a horizontal adjustment motor associated with the first web stabilising station in order to eliminate camber.

Filed: 1995-05-25
Abstract: A fiber optic cable (10) according to the present invention includes at least one lengthwise extending channel (16) surrounding an elongate central support member (14) with each channel defining a channel axis (18). At least one optical fiber (20) is positioned within each channel (16) and has an average position offset in a direction generally radially inward from the channel axis (18) toward the central support member (14) at about room temperature. In one embodiment, the at least one channel is defined by one or more buffer tubes (16) stranded about the central support member (14). In another embodiment, the at least one channel is defined by core having one or more lengthwise extending slots. The fiber optic cable (10) may also include a protective jacket (22) surrounding the central support member (14) and the channel defining means (16). The optical fibers (20) typically have a coefficient of thermal expansion less than the respective coefficient of thermal expansion of at least one of the protective jacket (22), the channel defining means (16) and central support member (14). Thus, by offsetting the average position of the optical fibers at about room temperature in a direction extending generally radially inward from the channel axis (18), the thermal contraction window of the fiber optic cable (10) is thereby increased.
