Title: Method and apparatus for automatic repetition rate assignment in a remote control system
Inventor: ETHIER LUC
IPC: H04L1/02
Filed: 1998-09-25
Abstract: The invention relates to a method and an apparatus for remotely controlling devices, more particularly to a system and method for controlling locomotives in a railway environment using radio frequency signals. This invention makes use of equalized pseudo-random transmission intervals obtained using a random number generator to regulate the times at which the signals are sent from a transmitter to a receiver. The use of these randomly generated transmission intervals allows eliminating the requirement of having an operator manage these intervals for transmitters in simultaneous operation. The invention also provides communication systems operating concurrently with substantially uniform response times by constraining the values of the transmission intervals to lie within a given range.

Title: Ingot mold for continuous casting of molten metal, particularly for forming rectangular or square-section steel billets
Inventor: MARTELLUCCI GIOVANNI
IPC: B22D11/04
Filed: 1999-05-05
Abstract: A substantially rectangular-section casting conduit of an ingot mold, for continuous casting of molten metal, is divided into two portions; a first portion has a variable inner section, by having rounded inner edges with a radius of curvature decreasing gradually in the flow direction of the molten metal along the conduit; the second portion is consecutive with the first portion, and has a constant inner section with rounded inner edges of a predetermined optimum radius of curvature for subsequent rolling operations. The design of the first portion of the casting conduit prevents the metal, as it cools and contracts through the conduit, from detaching from the walls, and in particular from the edges, of the mold, thus enabling an increase in casting speed with no fall in product quality.

Title: Method and apparatus for training of sensory and perceptual systems in lli subjects
Inventor: MERZENICH MICHAEL M
IPC: G09B5/04
Filed: 1998-12-14
Abstract: The apparatus and method incorporates a number of different programs to be played by the subject. The programs artificially process selected portions of language elements, called phonemes, so they will be more easily distinguished by an LLI subject, and gradually improves the subject's neurological processing of the elements through repetitive stimulation. The programs continually monitor a subject's ability to distinguish the processed language elements, and adaptively configures the programs to challenge and reward the subject by altering the degree of processing. Through adaptive control and repetition of processed speech elements, and presentation of the speech elements in a creative fashion, a subject's temporal processing of acoustic events common to speech are significantly improved.

Patent CA-2289930-A1 (CA)
Inventor: RAVKIN ILYA
IPC: G02B21/16
Filed: 1998-05-12
Abstract: Detection of fetal nucleated red blood cells (NR-BCs) is achieved by employing a combination of bright-field and fluorescence images of nuclear and cytoplas-mic markers. The brightfield and fluorescence images are all obtained with a single multi-bandpass dichroic mirror. The objects in the sample are stained with a fluorescent dye that selectively stains nuclei and a dye that selectively stains fetal hemoglubin in the cytoplasm of fetal RBCs. UV excitation provides fluorescent emissions from the stained cell nuclei and visible illumi-nation provides brightfield transmission of light that is absorbed by the stained cytoplasm. The images are processed to determine regions where the fluorescent emissions by cell nuclei in response to the UV  exci-tation and the absorption by fetal hemoglobin of the brightfield illumination overlap or are in close proximity. The brightfield and fluorescence images may be sequentially acquired or derived from a single image where the UV excitation and visible illumination occur simultaneously.
