Patent CA-2111572-A1 (CA)
Inventor: KRAVITZ DAVID W
IPC: H04L9/32
Filed: 1992-07-24
Abstract: A method is provided for generating and verifying a digital signature of a message m. This method requires a pair of corresponding public and secret keys (y and x) for each signer, as well as a pair of public and secret values (r and k) generated for each message by the signer. The public value r is calculated according to the rule r = (g k mod p) mod q. A value s is then selected according to the rule s = k-1(H(m) + xr) mod q where H is a known conventional hashing function. The message m, along with the signature (r, s) is then transmitted. When the transmitted signal is received a verification process is provided. The received values of r and s are tested to determine whether they are congruent to 0 mod q. Additionnally, r is tested to determine whether it is equal to v mod q, where v is computed from r, s, m and y. For legitimately executed signatures, v = g k mod p.

Abstract: PCT No. PCT/GB92/01579 Sec. 371 Date Apr. 8, 1994 Sec. 102(e) Date Apr. 8, 1994 PCT Filed Aug. 28, 1992 PCT Pub. No. WO93/05596 PCT Pub. Date Mar. 18, 1993.An optical transmission system including an interferometer and a source of optical signals. The interferometer comprises a four-pod optical coupler having first and second input ports and first and second output pods, a silica optical fiber coupling the first and second output pods which exhibits the Kerr optical non-linearity, and an erbium fiber optical amplifier situated asymmetrically between the output ports. The source of optical signals is coupled to the first input port of the interferometer. The system is operated in a regime in which the optical signals saturate the amplifier thereby suppressing any oscillatory output, and their power is sufficient to switch an input signal coupled to the first input pod to the second input pod. This provides pulse shaping and amplification characteristics which are relatively insensitive to the input power of the optical signals from the optical source.

Patent CA-2126380-A1 (CA)
Inventor: CHOU WU
IPC: G10L15/06
Filed: 1994-06-21
Abstract: A  method of making a speech recognition model database is disclosed. The database is formed based on a training string utterance signal and a plurality of sets of current speech recognition models. The sets of current speech recognition models may include acoustic models, language models, and other knowledge sources. In accordance with an illustrative embodiment of the invention, a set of confusable string models is generated, each confusable string model comprising speech recognition models from two or more sets of speech recognition models (such as acoustic and language models). A first scoring signal is generated based on the training string utterance signal and a string model for that utterance, wherein the string model for the utterance comprises speech recognition models from two or more sets of speech recognition models. One or more second scoring signals are also generated, wherein a second scoring signal is based on the training string utterance signal and a confusable string model. A misrecognition signal is generated based on the first scoring signal and the one or more second scoring signals. Current speech recognition models are modified, based on the misrecognition signal to increase the probability that a correct string model will have a rank order higher than other confusable string models. The confusable string models comprise N-best word string models. The first recognizer scoring signal reflects a measure of similarity between the training string utterance signal and the string model for that utterance. The second recognizer scoring signal reflects a measure of similarity between the training string utterance signal and a confusable string model. The misrecognition signal reflects a difference of the first scoring signal and a combination of one or more second scoring signals. The modification of current speech recognition models is accomplished by generating a recognition model modification signal according to a gradient of a function, which function reflects a recognizer score of a training string utterance based on a string model for that utterance and one or more recognizer scores of the training string utterance based on one or more confusable string models.
