Title: Reversible nuclear genetic system for male sterility in transgenic plants
Inventor: CIGNAN ANDREW M
IPC: C07K14/415
Filed: 1995-12-07
Abstract: Plant development can be altered by transforming a plant with a genetic construct that includes regulatory elements and DNA sequences capable of acting in a fashion to inhibit pollen formation or function, thus rendering the transformed plant reversibly male-sterile. In particular, the present invention relates to the use of dominant negative genes and an anther-specific promoter. Male sterility is reversed by incorporation into a plant of a second genetic construct which represses the dominant negative gene. The invention also relates to novel DNA sequences which exhibit the ability to serve as anther-specific promoters in plants.

Title: System for electronic newsgathering, documentary video, and photojournalism
Inventor: MANN STEVE
IPC: H04N5/225
Filed: 1998-04-14
Abstract: A novel system for a new kind of electronic news gathering and videography is described. In particular, a wearable camera with viewfinder means, wearable computational means, and wireless communication is introduced. A journalist wearing the apparatus becomes, after adaptation, an entity that seeks, without conscious thought or effort, an optimal point of vantage and camera orientation. Moreover, the journalist can easily become part of a human intelligence network, and draw upon the intellectual resources and technical photographic skills of a large community.  Because of the journalist's ability to constantly see the world through the invention, which may also function as an image enhancement device, the apparatus behaves as a true extension of the journalist's mind and body, giving rise to a new genre of documentary video. In this way, it functions as a seamless communications medium that uses a reality-based user-interface.
Patent CA-2235251-A1 (CA)
Title: Method and system for implementing software objects
Inventor: ORR MICHAEL B
IPC: G06F9/44
Filed: 1996-10-16
Abstract: The present invention provides a new system for implementing software objects using an object-prototype model. Objects are defined as collections of properties, each having a unique property name. A collection of property names defines a "shape". The use of shapes frees the representation of an object in memory from the order in which the properties of the object are declared.  Methods are defined independently of objects and are applicable to a specified shape, rather than to objects that are derived from a class in which the method is defined. Methods can be applied to any object that has the specified shape or that has a superset of the properties defining the specified shape, regardless of the place of the object in any inheritance hierarchy. The definition of a shape can also include additional selection criteria, such as restrictions on the values of properties, so that the application of a method can be restricted to objects satisfying the specified criteria. The properties of objects can be divided into subgroups representing different aspects of the object and different subgroups of an object can be inherited from different parent objects, based upon either a has-a or an is-a hierarchy. The shape of an object is determined by all of its properties and is not confined by subgroup boundaries.
Patent CA-2241323-A1 (CA)
Title: Leak prevention in blood oxygenators
Inventor: ELGAS ROGER J
IPC: A61M1/18
Filed: 1997-01-15
Abstract: A tight seal is achieved in a blood oxygenator (10) between the potting of the heat exchanger fibers (22) and the rim (42) of the heat exchanger container (14) by extending the potting material (26) over the rim (42) and down, so that when the potting material (26) shrinks during cure, the potting (26) will become prestressed in the sealing direction against an outwardly facing wall of the container (14). The invention also provides a ring (50) coextensive with the rim (42) and spaced therefrom. The potting (26) extends into the ring (50). This forms an air gap (62) between the rim (42) and the ring (50) through which potting (26) can extend. As a result, there is no possible leakage path between the blood and the heat-exchange medium. Any leak that does occur discharges to atmosphere outside the container (14).

Patent CA-2244962-A1 (CA)
Title: Dental burr
Inventor: WAUCHOPE FREDERICK T
IPC: A61C3/02
Filed: 1995-02-03
Abstract: A dental burr (10) is provided, whose use is specifically intended for the preparation of a tooth on which will be subsequently placed a crown, inlay, onlay, or other dental prosthetic. For any crown, inlay, onlay, or other bridge prosthodontic procedure, it is important that a series of grooves first be cut to a specific and predetermined depth, after which the lands that are created and stand between the grooves in the enamel and/or dentin of the tooth, will be ground down. However, the depth of the groove must be accurate. The dental burr of the present invention assures accuracy by providing a structure that has a cutting projection (20) that extends outwardly beyond a shoulder (26) that is formed in the burr, where the length of the cutting projection outward of the shoulder is a specific and predetermined length. Thus, a groove of a specific depth can be cut by using a specific burr. An intermediate portion (24) of the burr, which terminates in the shoulder, may be of a specific colour which is indicative of a specific length of the cutting projection. The intermediate portion may be formed by being machined into the material from which the burr has been manufactured, or it may be formed by placing a cylindrical sleeve (34) over a previously manufactured burr and fixing it in place so that the cutting projection is of the specified length.
