Patent CA-2245767-A1 (CA)
Title: Load-limiting seat
Inventor: LOU KEN-AN
IPC: B60N2/427
Filed: 1997-02-07
Abstract: A leg assembly (22) for mounting passenger seats in transport vehicles especially configured to absorb energy, in the event of a survivable crash or other sudden deceleration. The seat legs deform in a controlled manner to prevent loads at its floor attachment points from exceeding the magnitude of allowable floor strength. The leg assembly includes a base member (30) whose forward and rear ends attach to the floor, and a V-leg (40) whose lower vertex pivots about an axis passing through the front of the base member in the event of a forward crash.      The V-leg has a vertical member (40v) and a diagonal member (40d).      A load-limiting strut (36) connects the rear end of the base member to an intermediate area on the diagonal member of the V-leg. A tension link (38) connects the intermediate area of the V-leg and to the upper end of the vertical member of the V-leg. Elongation of the load-limiting strut allows the seat and legs to pitch forward at a predetermined inertial loading which, if exceeded substantially, would rip the seat loose from the floor. The tension link elongates at a predetermined load to distribute the loads within the seat.

Title: Design-a-rap
Inventor: SPARK KEITH B
IPC: G06Q30/02
Filed: 1998-12-07
Abstract: DESIGN A-RAP is manufactured by a laser or bubble printer which is designed to print a brief customized message on occasion-related gift wrapping paper (or shopping bags, or gift boxes) to enhance the appeal of customer purchases in businesses such as retail stores, catalogue firms and gift shops.      DESIGN-A-RAP incorporates software (yet to be designed) which would enable the computer operator to program customer-designed messages from his (the operator's)own language into any other major language, and embellished it appropriately with graphics or motifs appropriate to the customer's ethnic, cultural, or national requirements.      Note: as the prospective software is limited in nature (i.e. limited to gift greetings for special occasions), software design should be relatively simple to create using a team of translation experts with access to international "banks" of cultural, and national greetings, along with appropriate graphics to match the greeting.      Once a method for designing the above software has been established, DESIGN-A-RAP, theory could be used as a basis for creating other communications systems; for example, an operator could draft a bulletin for an international sales convention, initially in his own language, and later in any of the major languages included in his software--ergo, instant translation.

Title: Speech detection system employing multiple determinants
Inventor: COX GEOFFREY MARSHALL
IPC: G10L25/90
Filed: 1997-03-31
Abstract: A speech detection system (10) is provided with multiple speech detector sub-systems (11, 13, and 15). The speech detection sub-systems (11, 13, and 15) employ distinct statistical methods for determining whether speech is present in an electronic communication signal received at an input terminal (12). For example, a first speech detection sub-system (11) employs a moving average peak signal filter (20), a second speech detection sub-system employs a moving average noise filter (22), and a third speech detection sub-system employs a variance filter (24). Signals from each of the filters (20, 22, and 24) are compared with respective threshold values, and the threshold values are provided to speech determination logic (40) for making an aggregate speech detection decision. The speech detection system is useful for telephonic automatic gain control.

Patent CA-2278108-A1 (CA)
Title: Three-dimensional measurement method and apparatus
Inventor: KOFMAN JONATHAN D
IPC: G01B11/25
Filed: 1999-07-20
Abstract: The apparatus and method measure the three-dimensional surface shape of a surface without contact with the surface, and without any physical constraint on the device during measurement. The device is a range-sensor or scanner, and in one embodiment is a laser--camera sensor, which has a portable camera and multi-line light projector encased in a compact sensor head, and a computer. The apparatus provides three-dimensional coordinates in a single reference frame of points on the surface. The sensor head does not have to be physically attached to any mechanical positioning device such as a mechanical arm, rail, or translation or rotation stage, and its position in three-dimensional space does not have to be measured by any position-tracking sensor. This allows unrestricted motion of the sensor head during scanning, and therefore provides much greater access to surfaces which are immovable, or which have large dimensions or complex shape, and which are in confined spaces such as interior surfaces. It also permits measurement of a surface to be made by a continuous sweeping motion rather than in stages, and thus greatly simplifies the process of measurement. The apparatus can be hand-held, mounted on any moving device whose motion is unknown or not accurately known, or airborne. The apparatus and method also permit unknown and unmeasured movement of the object whose surface is to be measured, which may be simultaneous with the movement of the range-sensor head.
