Patent CA-2232952-A1 (CA)
Inventor: GALIC GEORGE J
IPC: B29C45/64
Filed: 1996-09-20
Abstract: Plastic injection-compression multi-cavity molding of flash-free improved cleanliness thermoplastic spectacle lenses (16) which are suitable for robotic dip hardcoating. Spring-loaded (25, 26) molds (13, 14) having variable-volume cavities are used in an injection-compression molding process to form, without parting line flash, pairs of a wide range of differing optical power polycarbonate prescription spectacle lenses (16). These pairs have molded-on design features which are specifically suited for full automation of the process, starting with ejection out of the mold into a takeout robot (43, 60) which is integrated via full automation with a subsequent dip hardcoating. A  molded-on tab (1, 3, 4) with each pair or lenses (16) is specifically suited for manipulation by a SCARA-type robot (43, 60). This combination produces micro-clean, hardcoated, paired, molded lenses made entirely within a single cleanroom air enclosure, without any human operators therein, and without requiring any cutting or trimming of the molded lens pair or runner system before hardcoating or the use of FREONTM CFC or aqueous cleaning protocols before dip hardcoating.

Patent CA-2237866-A1 (CA)
Inventor: ZHU QINGSHENG
IPC: A61N1/37
Filed: 1998-05-19
Abstract: An implantable cardiac rhythm management device 10 includes a microprocessor-based controller 28 adapted to receive digitized electrogram signals from leads 14 placed on or in the heart and incorporates an autosense algorithm which is called into play when an electrogram is detected that exceeds an event detect threshold ET and capable of adjusting a sensing threshold ST to improve detection of cardiac depolarization signals in the presence of noise.      The sensing threshold is automatically set on a beat-to-beat basis at a level that is dependent on a predetermined percentage of the peak amplitude of a current and an immediately preceding sensed or paced beat. The event threshold ET, which is always set at 50% of the sensing threshold, provides noise discrimination. The predetermined percentage value applied to the average peak value in arriving at the sensing threshold ST is dependent upon relative amplitudes of electrogram excursions and the signal-to-noise ratio encountered.

Patent CA-2241922-A1 (CA)
Title: Material having a substance protected by deformable standoffs and method of making
Inventor: HAMILTON PETER WORTHINGTON
IPC: C09J7/22
Filed: 1997-01-08
Abstract: A substance delivery system has a three-dimensional structure with outermost surface features (18) and spaces for containing a substance (16). The substance has a level below the outermost surface features such that the substance is protected from inadvertent contact with external surfaces. The substance remains protected until the three-dimensional structure is sufficiently deformed into a substantially two-dimensional structure and the substance is thereby exposed to contact an external surface (20) without compliance of the external surface being necessary. Deforming is preferably achieved by a compression force (F), wherein the outermost surface features (18) of the three-dimensional structure deform in a direction of the compression force. A method of making the three-dimensional material includes the steps of coating a substance onto a forming surface, transferring the coating of substance from the forming surface to a piece of material, and forming the piece of material into a three-dimensional structure on the forming surface while the substance is in contact with the forming surface.
Patent CA-2242150-A1 (CA)
Title: Display techniques for three dimensional virtual reality
Inventor: ENSOR JAMES ROBERT
IPC: G06T15/10
Filed: 1998-06-30
Abstract: A limitation of a three-dimensional world in which objects in the distance may be represented in only two dimensions as a video on a screen is that when an object within the field represented by the video undergoes a trajectory that takes it to a location in the world that is not represented by the video but instead is a location in the foreground which is represented by computer graphics, namely, any portion of the object that is no longer on the video screen disappears. To overcome this limitation, when an object within the field represented by the video undergoes a trajectory that takes it to a location in the world that is not represented by the video but instead is a location in the foreground which is represented by computer graphics, such an object, or portion thereof, is made to continue to be visible to the user by representing it at the foreground location to which its trajectory was carrying it using computer graphic techniques, rather than video. Thus, the video object "pops" out of the video and becomes visible, e.g., in front of, or to the side of, the video screen, rather than becoming invisible because it is no longer on the video screen.

Title: Barking dog sound alarm system
Inventor: RALPH LEO N
IPC: G08B15/00
Filed: 1999-02-02
Abstract: An alarm system uses the menacing sounds of a dog to scare away intruders. The alarm system includes a microphone for detecting noise, a comparator for comparing the detected noise level to a reference level so as to determine whether the detected noise is a potential intruder, sound recordings of different excited dogs, and a speaker for broadcasting a user-selected recording. A controller initiates broadcasting of a selected recording if the comparator determines that a detected noise is an intruder.  The controller varies the volume of the broadcast recording to simulate movement of a dog about the interior of a dwelling or enclosure.

Patent CA-2273172-A1 (CA)
Inventor: ARAI TAKASHI
IPC: A61F2/958
Filed: 1999-05-28
Abstract: A balloon catheter is provided with a core insertable from a connector into an inside of a shaft. When an operation for insertion/retraction of the core is carried out by pinching an operating part, the core slides along the shaft and the depth of the core in the shaft is thereby adjusted. When the core is inserted deeper in the shaft, the region of the shaft with a high rigidity increases with the core out to the shaft's distal end. On the other hand, when the core is retracted to the fore side, the rigidity of the shaft at its distal end side becomes lower and the flexibility of the balloon catheter becomes higher.
