Patent CA-2156871-A1 (CA)
Inventor: NEWBERRY THOMAS PATRICK
IPC: H04N5/445
Filed: 1995-08-24
Abstract: Des signaux analogiques et numériques représentent chacun une image et peuvent porter chacun des informations de guide de programmation. Un démultiplexeur utilise le signal vidéo numérique comme entrée et les informations de guide de programmation comme sortie. Un démodulateur utilise au moins un élément de luminance du signal vidéo numérique comme entrée et les informations de guide de programmation comme sortie. Un microprocesseur, un adaptateur de graphiques vidéo, le démultiplexeur et le démodulateur sont interconnectés par un bus de données. Chacune des sorties de guide de programmation peut être transférée à l'adaptateur de graphiques vidéo qui formate un signal vidéo de graphiques représentant les informations de guide de programmation. Le signal vidéo de graphiques et un signal sélectionné parmi les signaux vidéo sont des entrées dans un multiplexeur qui émet un signal vidéo mixte représentant aussi bien les informations de guide de programmation que l'image représentée par le signal vidéo sélectionné.

Abstract: An improved expandable stent for implantation in a body lumen,  such as an artery,  and an improved method for making it from a single length of tubing.  The stent consists of a plurality of radially expandable cut cylindrical elements generally aligned on a common axis and interconnected by one or more  interconnective  elements,   the  elements  having  a rectangular cross-section from cut-to-cut.   The individual radially expandable cylindrical elements are disposed in an undulating pattern.  The stent is manufactured by direct laser cutting from a single metal tube using a finely focused laser beam passing through a coaxial gas jet structure to impinge on the working surface of the tube as the linear and rotary velocity of the tube is precisely controlled.
Patent CA-2166239-A1 (CA)
Inventor: TAYLOR MATTHEW WHITING
IPC: G10L15/04
Filed: 1995-12-28
Abstract: A speech presence detector (101) includes a circuit input (105) to couple to a source of input signals.  A control signal generator (113) generates control signals.  A sampling circuit (112) samples the input signals as a function of the control signal. A processor (116, 616, or 916) is coupled to the sampling circuit to receive the signal samples. The processor is responsive to the sampled signals to identify a background noise threshold and detect the presence of speech.  According to one embodiment, the method and apparatus employ a random control signal.  According to another embodiment, the average frequency of the control signal is below the Nyquist rate.  According to another embodiment, the processor is responsive to the received signal to count the number of samples within a predetermined amplitude range and identifies a background noise threshold from the number of samples which are in the predetermined range.
Patent CA-2166551-A1 (CA)
Title: Computationally efficient adaptive bit allocation for coding method and apparatus
Inventor: DAVIDSON GRANT ALLEN
IPC: G10L19/035
Filed: 1994-07-19
Abstract: The invention relates to computationally efficient sophisticated perceptual models which can provide a basis for adaptive bit allocation and quantization of encoded information useful in high-quality low bit-rate coding systems. In one embodiment, an audio split band encoder splits an input signal into frequency subband signals, quantizes the subband signals according to values established by an allocation function, and assembles the quantized subband signals into an encoded signal. The allocation function establishes allocation values in accordance with psychoacoustic principles based upon a masking threshold. The masking threshold is established by estimating the power spectral density (PSD) of the input signal, generating an excitation pattern by applying a spreading function to the PSD, adjusting die excitation pattern by an amount equal to a signal-to-noise ratio (SNR) offset sufficient to achieve psychoacoustic masking, comparing the level of the adjusted pattern to the threshold of hearing and generating a masking threshold which is equal to the larger of the two. The spreading function may be implemented by applying one or more non-recursive filters to the input signal PSD. In forward-adaptive coding systems, allocation values are explicitly conveyed to a decoder by information assembled into the encoded signal. In backward-adaptive coding systems, allocation values an implicity conveyed to a decoder by information assembled into the encoded signal from which a decoder allocation function may derive the allocation values. In hybrid-adaptive coding systems, basic allocation values are conveyed implicitly with modified allocation values conveyed explicitly.

Abstract: A method and apparatus for closed loop, automatic pro-cessing a loan, including completion of the application under-writing, and transferring funds, includes use of a programmed computer (34) to interface with an applicant, obtain the informa-tion needed to process the loan, determine whether to approve the loan, and effect electronic fund transfers to the applicant's deposit account and arrange for automatic withdrawals to repay the loan. Information is received from the applicant preferably by using voice recognition technology (30) but alternatively by entering the alpha-numeric information using a personal com-puter (34) keyboard or using buttons on a telephone (12). The loan approval determination is made using a neural network (17) with input obtained in part from the applicant and in part from databases (14) accessed by the computer (34), such as a credit bureau (16), to obtain a credit report. The loan agreement is transmitted by facsimile to and from the applicant when the ap-plicant has access to a facsimile machine (18) of data field to be printed (37) or to an agent (22) who delivers the agreement to the applicant when the applicant does not have access. In a preferred embodiment, the applicant accesses the computer (34) from a kiosk (40) where the complete transaction can take place as the applicant waits.

Title: Silk hat type flexible mesh engagement gear device
Inventor: TAKIZAWA NOBORU
IPC: F16H49/00
Filed: 1995-12-14
Abstract: The silk-hat-shaped flexible external gear (13) of a silk-hat flexible meshing gear device (11) comprises a body (22), a diaphragm (23) and a boss (25). Between the main portion of the body (22) and a curved portion (222) is formed a thinned portion (221) whose thickness is about 80% that of the main portion. The thickness of the diaphragm (23) is defined to be largest at the inner edge (point A), smallest at the middle portion (point B) and slightly smaller than the largest thickness at the outer edge (point C). To make the change in thickness smooth throughout, the contour is defined by use of a group of curved lines (223, 224). Providing the thinned portion (221) and defining the thickness of the diaphragm (23) in the foregoing manner relieves stress concentration at the inner and outer edges and smooths the stress distribution.      As a result, the axial length and the outer diameter can be reduced to realize a compact silk-hat flexible meshing gear device.

Filed: 1995-02-24
Abstract: The present invention relates to the management of chronic pain without requiring administration of narcotics, and to self-management of pain on an outpatient basis. The invention further relates to facilitating detoxification and treatment of substance addiction. Accordingly, the present invention is broadly directed to a method for treating pain in a subject comprising administering via a nasal route a dose of ketamine effective to alleviate pain to a subject suffering from pain. The invention is further directed to a method for facilitating detoxification and treating substance addiction in a subject comprising administering via a nasal route a dose of ketamine effective to facilitate detoxification or treat substance addiction. In a further embodiment, the present invention provides for pulmonary administration of ketamine by inhalation. Nasal administration of ketamine advantageously allows for patient self administration of the drug, which provides for pain management or treatment of a substance addiction on an outpatient basis. Moreover, ketamine administration in nasal sprays and inhalers are generally socially acceptable. In a specific example, a patient suffering from intractable bladder pain controlled breakthrough pain by nasal administration of about 16 mg to about 32 mg of ketamine per dose.
