Patent CA-2202514-A1 (CA)
Inventor: WRIGHT GRAHAM
IPC: A61B5/117
Filed: 1995-08-24
Abstract: An apparatus for imaging skin ridges comprises a light transmissive body (1) having a surface (2) for receiving a relief pattern (3) from, for example, the pad of a finger, and a light source (4) which illuminates the surface and generates an optical image (5) of the relief pattern. A light transmissive heating element (7) is provided adjacent the surface of the body to heat the skin ridges in operation. The increase in the temperature of the skin makes it more flexible. It also promotes sweat secretion. Both factors improve the optical coupling between the finger and the surface resulting in more reliable fingerprint imaging.

Abstract: A rectangular shaped mainframe of rigid and formable sheet material is preshaped to fit the wearer's chin, throat, and clavicle areas without allowing the action of swallowing to be hindered. The said mainframe has foam attached to the underside and is enclosed in a soft fabric slip cover for wearer comfort and hygiene. The said mainframe is held in place by means of an attached strap that encompasses the neck and has a hook and loop type closure that mates with a second attached strap. This same strap holds a comfort cushion at the back of the neck to take up the void when wearer is in the prone or semi-prone position. The said mainframe ends are placed against the chin and clavicle area and when the said straps encompass the neck and are adjusted they comfortably hold the chin in place so as not to let the head and chin drop or tilt forward reducing or shutting off air supply, but allow for free comfortable movement of head from side to side. When the head is held in a tilted position with mouth closed the wearer's respiratory airway is open to free flow and snoring is eliminated. A free flow of air to wearer's respiratory system provides a steady oxygen supply which relieves the symptom of sleep apnea.

Patent CA-2216793-A1 (CA)
Title: Optical multiplexing device and method
Inventor: STUPIK PAUL
IPC: G02B5/28
Filed: 1996-06-10
Abstract: An optical multiplexing device spatially disburses collimated light from a fiber optic waveguide into individual wavelength bands, or multiplexes such individual wavelength bands to a common fiber optic waveguide or other destination. The optical multiplexing device has application for dense channel wavelength division multiplexing (WDM) systems for fiber optic telecommunications, as well as compact optical instrument design. Multiple wavelength light traveling in a fiber optic waveguide is separated into multiple narrow spectral bands directed to individual fiber optic carriers or detectors. An optical block has an optical port for passing the afor esaid multiple wavelength collimated light, and multiple ports arrayed in spaced relation to each other along a multiport surface of the optical block. A continuous, variable thickness, multicavity interference filter (22) extends on the multiport surface (20) of the optical bl ock over the aforesaid multiple ports. At each of the multiple ports the continuous interference filter transmits a different sub-rang e of the multiple wavelength light passed by the optical port, and reflects other wavelengths. Multicolor light passed to the opt ical block from the optical port is directed to a first one of the multiple ports on an opposite surface of the optical block. The wavelengt h sub-range which is "in-band" of such first one of the multiple ports is transmitted through that port by the local portion of the cont inuous, variable thickness interference filter (22) there, and all other wavelengths are reflected. The light not transmitted through the first port (16) is reflected to strike a second port, at which a second (different) wavelength band is transmitted and all other light again re flected. The reflected optical signals thus cascades in a "multiple-bounce" sequence down the optical block (10) of the multiplexing devic e, sequentially removing each channel of the multiplexed signal. In reverse operation, individual channels are combined in the optical bl ock and transmitted through the optical port.

Patent CA-2219056-A1 (CA)
Inventor: MINOWA TOSHIMITSU
IPC: G10L13/07
Filed: 1997-10-23
Abstract: A speech synthesizing system using a redundancy-reduced waveform database is disclosed. Each waveform of a sample set of voice segments necessary and sufficient for speech synthesis is divided into pitch waveforms, which are classified into groups of pitch waveforms closely similar to one another. One of the pitch waveforms of each group is selected as a representative of the group and is given a pitch waveform ID. The waveform database at least comprises a pitch waveform pointer table each record of which comprises a voice segment ID of each of the voice segments and pitch waveform IDs the pitch waveforms of which, when combined in the listed order, constitute a waveform identified by the voice segment ID and a pitch waveform table of pitch waveform IDs and corresponding pitch waveforms. This enables the waveform database size to be reduced. For each of pitch waveforms the database lacks, one of the pitch waveform IDs adjacent to the lacking pitch waveform ID in the pitch waveform pointer table is used without deforming the pitch waveform.

Filed: 1997-11-10
Abstract: A heart muscle irrigation device comprises a short rivet like member with one closed and one open end, and a barrel including a plurality of holes, slots, an area mesh, or a grid. The irrigation device is inserted into the heart muscle so as to provide a channel from, for example, the left ventricle, to provide ad adequate oxygenated blood supply to a starved muscle.

The insertion device comprises a plunger and barrel assembly adapted to contain the irrigation device. The tip of the insertion device includes members adapted to penetrate the heart muscle. If the irrigation device is inserted through an insertion into the rib cage, an applicator comprising a tubular member with a planar tip including a soft elastomeric seal can be used whereby a portion of the heart muscle is held more or less rigidly for the short period during which the irrigation device is inserted. These devices, even when a rib cage insertion is made, do not require either the life support systems of the extensive rib cage damage associated with conventional bypass surgery.

IPC: A61M21/00
Filed: 1998-03-06
Abstract: A photic stimulator for stimulating the central nervous system and the brain waves of a human subject having left and right eyes and left and right visual fields within each eye. The stimulator includes light assemblies providing pulsating light signals individually to the left and right visual fields of each of the left and right eyes of the subject and a control module for varying frequency and intensity of the light assemblies. The photic stimulator can stimulate the left and right visual fields of each eye independently of each other. This capability exploits the anatomical structure of the optic chiasm found within the human brain where stimuli of both eyes stimulates the side of the visual cortex opposite the side where the visual stimulation is seen in the visual field.
