Patent CA-2182814-A1 (CA)
Inventor: WILKINS LEON M
IPC: B65D77/20
Filed: 1994-09-14
Abstract: This invention is directed to cryopreservation of cultured tissue equivalents made by in vitro technology. The invention involves immersing a cultured tissue equivalent in a cooled cryoprotectant solution, agitating the cryoprotectant solution and the immersed cultured tissue to achieve effective penetration of the cryoprotectant solution into the cultured tissue equivalent, and then freezing the cultured tissue at a high freezing rate. The cryopreserved cultured tissue equivalent may be stored for indefinite periods of time prior to use. The cultured tissue equivalent is an in vitro model of the equivalent human tissue, which, when retrieved from storage can be used for transplantation or implantation in vivo or for screening compounds in vitro.
Patent CA-2184436-A1 (CA)
Title: Glass break sensor
Inventor: CECIC DENNIS
IPC: G08B13/04
Filed: 1996-08-29
Abstract: The glass break detector uses sampling techniques to a low band and a high band portion of a signal from a transient event to assess whether the bands are random.  In addition, an assessment of the envelope shape of the signal is made to confirm the signal is consistent with a rapid rise followed by a sloped decay typical of transient events.  It has been found that dividing of the signal into high and low bands and analyzing each portion over a short front end portion of a transient event is effective in distinguishing glass break events from other common events.

The structure is constructed such that an air intake port is located behind a first headlamp in the engine compartment, an opening of the air intake port is arranged in front of the compartment, and a rotational direction of a first cooling fan of a pair of cooling fans mounted on a rear side of a radiator at substantially the same height is determined such that the air discharged by the first cooling fan is directed away from the air intake port of the engine, and a rotational direction of the second cooling fan of the pair of the cooling fans is determined opposite to the first cooling fan, in which the first cooling fan is closer to the air intake port than the second cooling fan.  Furthermore, air volume discharged by the first cooling fan mounted closer to the air intake port in the pair of the cooling fans is set larger than that of the second cooling fan. Furthermore, rotational directions of a pair of cooling fans mounted on a rear side of a radiator at substantially the same height are determined such that the air discharged by the cooling fans is directed toward a space in the rear side of the other headlamp, and each air volume discharged by the respective cooling fan is set different.

Title: Optical waveguide grating and production method therefor
Inventor: YAMAUCHI RYOZO
IPC: C03B37/10
Filed: 1997-04-10
Abstract: A method of producing an optical waveguide grating by exposure to light.  An optical waveguide having a core composed of a material wherein the refractive index changes due to exposure to UV light is formed into an optical waveguide grating by applying a grating portion formation step wherein a grating portion is formed by irradiation with UV light at a predetermined spacing, and an overall exposure step after formation of the grating portion wherein the entire grating portion is irradiated with UV light.  As a result, the effective refractive index of the grating portion is changed so as to allow the central wavelength to be adjusted without changing the rejection.  Consequently, the grating properties can be precisely and easily controlled.

Lithium hydroxide, water and hydrogen peroxide are mixed and 1) passed over a lithium hydroxide solid bed or 2) premixed with small particulate solid lithium hydroxide or lithium hydroxide monohydrate. The basic hydrogen peroxide produced is chilled and stored cold until mixed with chlorine to produce singlet delta oxygen for use in the chemical oxygen iodine laser. The spent basic hydrogen peroxide is rejuvenated by passing it over a solid lithium hydroxide or in-situ solid particulate lithium hydroxides. After dissolution, the rejuvenated basic hydrogen peroxide is then reacted with chlorine to produce more singlet delta oxygen

Title: An apparatus for orienting and positioning an elongate object for dispensing
Inventor: BUNCE MARTIN
IPC: A61K9/48
Filed: 1997-06-23
Abstract: Apparatus for orienting elongate objects, for example capsules of medicament, comprises a passage for receiving an individual capsule in a preferred orientation, a container for holding a bulk supply of capsules, and a ramp surface which directs a capsule towards the passage when the device is positioned such that the passage extends vertically downwardly from the container. It has been found that by appropriate choice of ramp angle, passage diameter and container diameter there is a high probability that a single capsule will be loaded into the dispensing passage when the apparatus is inverted to place the dispensing passage below the bulk supply. The apparatus is particularly useful in a dry medicament dispensing apparatus comprising, in addition to the orienting apparatus, a chamber for receiving capsules from the dispensing passage, means for piercing the ends of the capsule, and a mouthpiece for drawing air through the capsule and to entrain the medicament.

Title: System and method for modification of the visual characteristics of digital 3d objects
Inventor: LAUZON LAURENT
IPC: G06T15/50
Filed: 1997-06-25
Abstract: A system and method for modification of the visual characteristics of digital 3D objects includes a shading buffer wherein parameters relating to the visual characteristics of a rendered 3D object are stored. When a texture applied to the 3D object is selected for modification, a pre-rendering step is performed and a shading buffer constructed. The shading buffer includes pre-computed components of the visual characteristic information for each rendered pixel of the displayed 3D object, these components are independent of the texture selected for modification. When the texture is modified, by indicating one or more pixels on the 3D object to which the texture is applied, re-rendering of those pixels is accomplished by evaluating a simple combination of the corresponding pre-computed components in the shading buffer and the modificationeffected to the selected texture obtain new final values to render the pixels. By pre-computing and arranging the components in the shading buffer, the computational requirements for re-rendering the modified portions of the 3D object are reduced, improving the re-rendering response of the system and method and allowing real time pre-rendering in many circumstances.
