Patent CA-2307907-A1 (CA)
Inventor: LOSEKE CHARLOTTE N
IPC: H04L27/22
Filed: 2000-05-09
Abstract: An innovative channelizer design methodology is provided to adjust the narrowband channel frequency spacing and processing algorithm in order to develop a configurable multi-rate channelizer (20) for multiple applications with different input data rates and input channel group bandwidths. Given an input and output sampling rate and the input channel group bandwidth, the input channel spacing, the discrete Fourier transform (DFT) size, the valid output DFT bins, the dead zone implementation including the number of samples to blank for each chip, which exact samples to blank, the timing error immunity versus performance degradation balance may be derived to design hardware implementation of a configurable multi-rate channelizer for use in applications with different input data rates and input channel group bandwidths. Using the innovative multi-rate channelizer design, a single configurable channelizer may be obtained and can be usable for multiple applications in different channelization modes of operation while realizing design gate savings.

Title: Methodes d'utilisation d'inhibiteurs de co-represseurs dans le cadre du traitement de maladies neoplasiques
Inventor: EVANS RONALD M
IPC: C07K14/47
Filed: 1998-11-10
Abstract: Cette invention a trait à l'utilisation d'inhibiteurs d'histone désacétylase en tant qu'activateurs de gènes, qui, réagissant à des récepteurs hormonaux, se révèlent efficaces pour entraver les fonctions oncogènes de protéines oncogènes. L'histone désacétylase atténue la répression dans des systèmes réprimés et, associée à un ligand spécifique d'un membre de la super-famille des hormones stéroïdienne/thyroïdienne, favorise le renforcement des effets de différentiation des rétinoïdes. L'invention concerne également des formulations destinées à moduler des processus déclenchés par des hormones ainsi que des épreuves visant à l'identification de modulateurs potentiels.

Title: Method and apparatus for determining logging tool displacements
Inventor: FREEDMAN ROBERT
IPC: E21B47/022
Filed: 2000-06-30
Abstract: A method of determining the displacements of a logging tool during a measurement interval of the logging tool in a borehole includes obtaining a set of accelerometer signals corresponding to accelerations of the logging tool along each of three orthogonal axes of the logging tool during the measurement interval. The method further includes calculating a lower bound for the displacements of the logging tool during the measurement interval when the initial velocity and the gravitational acceleration are unknown. The lower bound on the displacements of the logging tool is used to flag the validity of the measurements made by the logging tool.

Abstract: A system and method for obtaining an estimate of the concentration of an odor in an air sample from data obtained by evaluating the sample with a sensor-array type electronic nose. Principal components analysis is applied to a set of air sample data including sensor-array data obtained from evaluating the air sample with the sensor-array type electronic nose and measurements of the humidity of the air sample and clean reference air used by the electronic nose to obtain a predetermined number of principal components of the air sample data. The principal components obtained from the air sample are used as inputs to a neural network to obtain as output an estimate of the concentration of the odor in the air sample. The neural network uses parameters obtained by using an olfactometer to obtain discrete measurements of odor concentration from each of a plurality of calibration samples of air containing the odor, using the sensor-array type electronic nose to obtain a discrete set of calibration data from each of the calibration samples, each set including sensor-array data and measurements of the humidity of the calibration sample and the clean reference air used by the electronic nose, applying principal components analysis to each set of calibration data to obtain a discrete set of the predetermined number of principal components, and training a neural network using the sets of principal components as input data and the corresponding measured odor concentrations as expected output to obtain the parameters of a trained neural network.

Title: Leak-resistant cryptographic method and apparatus
Inventor: KOCHER PAUL C
IPC: H04L9/10
Filed: 1998-12-31
Abstract: The present invention provides a method and apparatus for securing cryptographic devices against attacks involving external monitoring and analysis. A "self-healing" property is introduced, enabling security to be continually re-established following partial compromises.   In addition to producing useful cryptographic results, a typical leak-resistant cryptographic operation modifies or updates (330) secret key material in a manner designed to render useless any information about the secrets that may have previously leaked from the system. Exemplary leak-proof and leak-resistant implementations of the invention are shown for symmetric authentication (350), certified Diffie-Hellman (when either one or both users have certificates), RSA, ElGamal public key decryption (303).

Title: Wheel flange lubrication nozzle
Inventor: SICH GARY M
IPC: B61K3/02
Filed: 2000-11-16
Abstract: A nozzle assembly allows a metered dose of lubricant to be dispensed. It comprises a housing and a piston assembly. The housing defines a piston bore, a stem bore and a spout, all of which axially aligned. It also defines a lubricant passage, an air inlet, and a channel linked to the inlet. Connectable to a source of lubricant, the passage communicates with the stem bore. Connectable to a source of air, the inlet communicates with the stem bore at a position between the passage and spout. The piston assembly has a piston with stem and a spring. The piston lies in the piston bore, its back communicating with the channel. The protrudent end of the stem protrudes into the stem bore and has a groove defined about its circumference.      The spring biases the piston assembly into a charge position wherein the groove aligns with the passage. This enables the groove to fill with lubricant. When the source of air allows air to act upon the back of the piston, the piston assembly moves against the spring through a transfer position. In this position, the stem extends further into the stem bore so that the groove lies between the passage and inlet. When fully moved against the spring, the piston assembly reaches a discharge position. In this position, the groove communicates with both the inlet and spout. This enables the lubricant to be discharged from the groove and out the spout along with the air from the inlet.

Abstract: An Internet-based system that facilitates the interaction between a store, its distributor, and consumers is disclosed. The system is centered around a distributor website that is designed to interact with both the stores it supplies and with the consumers who shop in those stores. Stores interact with the distributor's website by first using the site to create their own personalized website using a website "wizard." This wizard program allows stores autonomy in creating their websites and choosing which of the distributor's products they wish to sell on line, but also makes it feasible for the distributor to update all of the created websites with pertinent information such as product pricing. The stores may also use the disclosed system to purchase products from the distributor to stock their stores. Consumers may interact with the distributor's website by utilizing a store locator to locate a store in their vicinity. Thereafter, the consumers may order products on-line from the websites of their local stores. Stores may periodically check the status of on-line orders by logging into the system.
