Patent CA-2170800-A1 (CA)
Inventor: NEVIN MONIQUE A
IPC: A61H3/04
Filed: 1996-03-01
Abstract: The present invention is a hemi-wheeled walker which is particularly useful with respect to hemiplegics.      Patients of this type generally have one strong side of their body and one relatively weak side. Many patients have suffered from a stroke. The hemi-wheeled walker comprises an upright segment having a lower base portion extending parallel to the side of the user, with a handle at an upper portion thereof. The upright segment is a adapted for low force movement across a support surface when the user is supported on his strong side and adapted for gripping engagement with the support surface when the patient requires additional support when he is primarily supported by his weak side. A stabilizing segment is provided to one side of the upright segment and has at least one wheel at a point of contact of the stabilizing segment with the support surface. The stabilizing segment maintains the upright segment in an upright orientation and braces the upright segment against pivoting movement in a direction to the side of the user and towards the stabilizing segment. With this arrangement, the walker is designed to oppose or to minimize the patient falling to his strong side, which would be the tendency when the patient is supported on his weak leg and is moving his strong leg to the next position for walking. The low force movement of the walker across the support surface, when it is not used as a support aid, is highly desirable, as the patient is moving the walker generally with one hand and may otherwise have some difficulty in lifting and repositioning of the walker. It must be appreciated that many patients of this type are recovering and can be at various stages of recovery and often lack confidence. The support aid must be reliable and instill the confidence in the patient.

Patent CA-2178461-A1 (CA)
Title: Air purifier device
Inventor: MORROW WILLIAM
IPC: A61L9/12
Filed: 1996-06-06
Abstract: An air purifier has a perforated plate between UV lamps on the one hand and a porous air filter on the other. Biological material is trapped by the filter and eventually killed by the low dose of UV radiation which passes through the perforations in the plate. Filtered air passing through the plate is subjected to a high dose of UV radiation which sterilizes remaining biological material in the air. An electrostatic filter at the outlet may trap viruses which have been positively charged either by the action of the UV lamps or by positively charging the plate in order to strip electrons from the viruses. The UV lamps may be mercury lamps which are allowed to emit at both their ozone forming wavelength as well as the ozone breakdown wavelength. In such instance, a light filter surrounds the lamps which passes light only at the ozone breakdown wavelength. Air subjected to the unfiltered light is consequently subjected to ozone, which is a known biocide. The filtered light is in a zone which is filled with water mist such that hydroxyl radicals result. Air passing through this zone is scrubbed by the hydroxyl radicals.

Title: Well test imaging
Inventor: SLEVINSKY BRUCE A
IPC: E21B47/06
Filed: 1996-08-12
Abstract: An improved method is provided for establishing the location and orientation of the boundaries surrounding a reservoir and creating an image thereof. A conventional well test is performed on a well, establishing measures of the well's pressure response as a function of the rate of pressure change in the reservoir over time. Conventional techniques may be used to determine measures of the radius of investigation. A plurality of radii of investigation are determined as a function of time. A calculated response for an infinite and radially extending well are the measured response are compared as a ratio. Variation of the ratio from unity is indicative of the presence of a boundary at that radius of investigation and the magnitude of its effect related to an angle-of-view. Each radius of investigation is deemed analogous to a ring. Reservoir encompassed by this ring is in communication with the well. This ring is interrupted along its circumference by an encounter with a boundary or boundaries, the arc length of such an interruption being equal to the angle-of-view. The remaining arc of the ring is rotated so that at least one of the arc's end-points coincides, or is fitted, with a known geologic feature. Should the same ring arc intersect another feature, the ring arc is cut to form a new arc end-point. The remaining arc is rotated so that its new end-point again coincides with a geologic feature. Once all the ring arcs for each radius of investigation are fitted, their collective end-points form an image of the periphery of the reservoir.
