Title: All digital conference unit
Inventor: RAPATZ BRIGITTE R
IPC: H04M3/56
Filed: 1992-05-29
Abstract: ABSTRACT              AN ALL DIGITAL CONFERENCE CIRCUIT     In order to accomplish the object of the present in-vention there is provided a digital conference circuit for creating a conference call.  The digital conference circuit includes a time slot assigner that determines an appropriate time to extract from the PCM bit stream and to inject into the PCM bit stream.  There are a plurality of CHANNEL DSP that extract the digital voice samples from the PCM data stream, where each of the plurality of CHANNEL DSP extracts from the digital voice samples one unique digital voice sample that represents an individual party to the conference call.  After extracting the digi-tal voice samples, the plurality of CHANNEL DSP converts the samples from a logarithmic format to a linear format. The plurality of CHANNEL DSP next remove any echo from the linear voice samples.  Next, a CONFERENCE DSP re-ceives the linear voice samples from the plurality of CHANNEL DSP and determines their sum.  The plurality of CHANNEL DSP subtracts from the sum the digital voice sam-ple that represents the unique individual party, to cre-ate individual conference sum samples.  Finally, the plu-rality of CHANNEL DSP convert the individual conference sum samples to a logarithmic format.  The plurality of CHANNEL DSP then injects the logarithmic voice samples into the PCM data stream.

Abstract: EARWIG COLLECTOR            ABSTRACT OF THE DISCLOSURE:               An apparatus for and a method of collecting and disposing of earwigs is disclosed. The earwig collector of the present invention provides snug relatively dark passageways for earwigs to collect in. The apparatus is typically made of wood, preferably cedar, in order to be more attractive to earwigs.   Earwigs are removed from the passageways of the apparatus by separating the first and second body portions from one another thus exposing the earwigs that have collected in the passageways and knocking the first and second body portions against one another to jolt the earwigs therefrom. The earwigs preferably fall into a container of soapy water and drown.

Title: Method and system for personal identification using proofs of legitimacy
Inventor: LEIGHTON FRANK T
IPC: G07C9/00
Filed: 1990-11-02
Abstract: The method and system are used to generate and to verify a personal identification card. The method begins with the generation of the signature z (130). Then, the authorizing party stores the password on the card along with the signature z and one of four predetermined factors (132). The method continues with the presentation of the card for verification (134). Upon presentation of the card, a test is made to determine if a predetermined number of legitimacy proofs have been carried out (136). If the proofs have been carried out, then z is accepted (138). If the proofs have not been carried out, then a random number is generated, squared to yield y, and then y is supplied to the verifier (140). In response to receiving y, the transaction terminal randomly chooses a bit b, and sends the bit to the prover (142). If b = 0, then the prover sends a value x mod M back to the transaction terminal; and, if b = 1, then the prover sends xz mod M back to the transaction terminal (144). If b = 1 and yjQ mod M = W mod M for j, then testing for the number of proofs of legitimacy starts again, otherwise the card is rejected. If b = 0 and W mod M = y; then testing for the number of proofs of legitimacy starts again, otherwise the card is rejected.

IPC: G10L19/06

Abstract: A method for synthesizing human speech using a linear mapping of a small set of coefficients that are speaker-independent. Preferably, the speaker-independent set of coefficients are cepstral coefficients developed during a training session using a perceptual linear predictive analysis. A linear predictive all-pole model is used to develop corresponding formants and bandwidths to which the cepstral coefficients are mapped by using a separate multiple regression model for each of the five formant frequencies and five formant bandwidths. The dual analysis produces both the cepstral coefficients of the PLP model for the different vowel-like sounds and their true formant frequencies and bandwidths. The separate multiple regression models developed by mapping the cepstral coefficients into the formant frequencies and formant bandwidths can then be applied to cepstral coefficients determined for subsequent speech to produce corresponding formants and bandwidths used to synthesize that speech. Since less data are required for synthesizing each speech segment than in conventional techniques, areduction in the required storage space and/or transmission rate for the data required in the speech synthesis is achieved. In addition, the cepstral coefficients for each speech segment can be used with the regressive model for a different speaker, to produce synthesized speech corresponding to the different speaker.

Abstract: A sonic-type fluid flow measuring system wherein reflections or echoes of a burst (103) of ultrasonic en-ergy from an ultrasonic acoustic emitter (9a) are sensed and typically comprise a number of frequencies represen-tative of a number of discrete velocities of flow in a volume of fluid.  A receiver transducer (13a) is gated to receive echoes from a selected volume of fluid (104) a selected distance from a transducer (13a).  Thereafter, this time domain signal sample is converted to a frequen-cy domain sample whereby the presence and magnitude of each frequency component, or velocity component, is iso-lated, this being typically done by what is known as a Fast Fourier Transform unit, obtaining a frequency domain waveform representative of average flow velocity.

The cam actuated adjustment mechanism pivots such support member to adjust the foil angle without bending the foil.  In one embodiment a front set of cam slots and cam follower pins is provided to maintain the height of the leading edge of the foil substantially constant at different foil angles.  In a second embodiment the ends of the pins are connected to cam slide rods which extend across the pins and fit into the cam slots.  In a third embodiment, the front set of cam slots and pins is replaced by a pivot rod attached to the front of the mounting base member about which the foil and foil support member pivot in response to the rear cam actuator adjustment of the foil angle.
