Patent CA-2238904-A1 (CA)
Inventor: MARK JOHN G
IPC: G01C19/72
Filed: 1998-05-28
Abstract: A closed-loop system for regulating a fiber optic gyroscope is configured so that the residual error of a so-called deadbeat system assumes a higher order function of frequency.  The closed-loop gyro includes a rate controller within the feedback path.  The rate controller receives the gyro output from the last loop transit corrected for d.c. offset and for nominal dither and outputs a gyro rate estimate.  The rate controller includes a plurality of feedback integrators in cascaded relationship. In this way, the residual gyro error associated with inherent loop delay is elevated to a higher-order relationship to sensed gyro rate.  As a result, a substantial reduction in residual error as a function of sensed gyro rate occurs throughout the range of operational gyro frequencies.

IPC: H01R13/6464
Filed: 1998-08-10
Abstract: La présente invention a pour objet un structure à lames réglables destinée aux fiches utilisées comme terminaisons de câbles de communication constitués d'une pluralité de conducteurs. Une des extrémités des lames fait office de connexion autodénudante pour l'établissement de la continuité électrique avec les conducteurs du câble. L'autre extrémité des lames sert de plot de contact pour jack de liaison. Entre ces deux extrémités se trouvent trois régions permettant la manipulation des caractéristiques des lames : une région de couplage capacitif, une région de couplage inductif et une région d'isolation électrique. Le soin apporté à la configuration de ces trois régions permet la réduction optimale de l'interférence électrique (diaphonie) entre les conducteurs.

Patent CA-2252635-A1 (CA)
Inventor: GUTIERREZ ALEJANDRO
IPC: G01R31/00
Filed: 1996-05-16
Abstract: A portable diagnostic device for checking electrical signalling systems of road going trailers. The device has several receptacles for connection to a corresponding receptacle or pin connector of most types of trailers (20, 22, 39, 90, 92). An electrical circuit includes switches for energizing individual signalling or illumination circuits of the trailer individually, and indicating lamps for annunciating circuit operability. The device, which is contained on a wheeled cart, has its own power supply (34) and circuit overcurrent protective devices, and is thus independent of a tractor which normally generates the signals. Pumps for generating pneumatic and hydraulic pressure are provided for monitoring integrity of these systems of a trailer.  Auxiliary electrical systems, such as electric brakes, can also be monitored.  The device enables a shop to perform a safety check for many varieties of trailers, while remaining independent of the tractor vehicles associated with the trailers.

Title: Security and fashion solar lamps without extraneous current source
Inventor: GAEHWILER BENNO
IPC: F21S6/00
Filed: 1998-03-09
Abstract: The invention concerns a security and fashion solar lamp which operates without extraneous current sources or by means of accompanying spare batteries. Since situations in which it is highly important to be visible occur frequently with road traffic incidents and disasters and in dangerous working areas or extremely secluded areas, a system has been developed which allows the user to be seen without incurring great expense. The shape and colour of the lamp according to the invention can be freely varied to a greater or lesser extent depending on the intended use and also leave the design world a certain amount of latitude. The safety and fashion solar lamp comprises solar cells (4) which are attached to a movable foil. This solar cell light assembly (4) is used to generate current and feed the storage batteries (5) which, again according to the intended use, can be combined to form larger or smaller storage battery packs (5). Control electronics (6) regulate the processes for charging and discharging the storage batteries (5).  A sensitive switch or push-button (1) feeds the pulses for starting up the light element (2) to the control element (6). Depending on the use to which the lamp is put, the switching-on process is automated through a photocell (3).

Title: Cyclonic dirt cup assembly
Inventor: KEEBLER A RONALD
IPC: A47L9/16
Filed: 1999-09-30
Abstract: A cyclonic dirt cup assembly for a vacuum cleaner has a generally conical truncated cone positioned within a dirt cup of the vacuum cleaner. The dirt cup has a wall formed with an air inlet opening for receiving a stream of dirt-laden air within the dirt cup. The cone is pivotally connected to a frame member which is removably mounted within the dirt cup. A baffle extends outwardly from a wall of the cone and is positioned adjacent the air inlet opening of the dirt cup for directing the stream of dirt-laden air in a cyclonic manner. The baffle includes a top wall, a side wall and a bottom wall. The baffle walls, the wall of the dirt cup and a wall of the cone form an air directing compartment which receives the dirt-laden air input through the inlet opening. The air directing compartment is formed with a side exit opening which provides a tangential opening for the dirt-laden air to exit the air directing compartment and begins a cyclonic action within the container for filtering dirt particles from the airstream. A filter is positioned on the frame member opposite the cone for further filtering the airstream. The cone pivots away from the frame member to provide access to the filter for cleaning thereof.

Title: Cocktail watermarking on images
Inventor: LU CHUN-SHIEN
IPC: H04N1/32
Filed: 1999-10-05
Abstract: A novel image protection scheme named "cocktail watermarking" improves over current spread-spectrum watermarking approaches. Two watermarks, which play complementary roles, are simultaneously embedded into an original image. The new watermarking scheme has the characteristic that, no matter what an attack is, at least one watermark typically survives well and can be detected.      Results of extensive experiments indicate that our cocktail watermarking scheme is effective in resisting various attacks.
