IPC: H04H20/00
Filed: 2000-05-30
Abstract: A communication structure and method which allows connection-like and connectionless communications to be provided on a multiplexed link is provided. The structure and method can make efficient use of available transmission capacity and/or network resources while providing for both types of communication. Connection-like communications can be provided by a channel having allocated bandwidth dedicated to the communication while connectionless communication can be provided by a shared channel through which data can be transmitted to subscribers.

The frames can have a robustly packaged header that can be received by all subscriber stations serviced by the base station while payload data in the frame can be packaged with a level of robustness appropriate for the intended subscriber station. Different packagings can include different encoding and/or modulation of the payload data. The allocation of bandwidth between the dedicated channels and the broadcast channel can be fixed, or can be managed to meet network or network operator requirements. The structure and method can also be managed by the network operator to permit prioritization of some communications over others. In another embodiment, two or more shared channels are provided. In another embodiment, dedicated channels can be created with different amounts of bandwidth and/or can employ modulation and/or encoding selected according to the reception-quality of the recipient subscriber station.

Patent CA-2323120-A1 (CA)
Inventor: RUCKERT DIETER
IPC: B60W10/101
Filed: 2000-10-13
Abstract: A control device for an infinitely variable transmission includes a control lever that is movable along a guide slot and whose position within the slot indicates the commanded speed and direction. The control lever is moved forward from a zero speed position to a maximum forward speed position. Between the zero speed position and maximum forward speed position is a set point position corresponding to a set point speed. A set speed adjuster, such as a potentiometer, enables the operator to adjust the set point speed that is commanded when the control lever is placed in the set point position. The speed for positions of the control lever between the zero and the set point positions varies proportionally between zero and the set point speed. Likewise, the speed for positions of the control lever between the set point position and the maximum forward speed position varies proportionally between the set point speed and the maximum forward speed.

Patent CA-2333740-A1 (CA)
Inventor: HOLDEN JOHN GRAHAM
IPC: G02B27/22
Filed: 1999-05-28
Abstract: The apparatus comprises an object (10) for display, a retro-reflector (12) receiving light from the object, a beam-splitter (14) in a path (16) for light from the object to the retro-reflector, and a Fresnel lens (20) (having no point of central symmetry) between the beam-splitter and the retro-reflector.  The beam-splitter (14) makes an oblique angle to the direction of propagation of the light, such that it transmits some light and reflects the rest. Light from the beam-splitter passes through the lens (20) to the retro-reflector (12), which reflects it back through the lens to the beam-splitter. This retro-reflected light is reflected and/or transmitted by the beam-splitter to form a real image (18) suspended in space. The type of Fresnel lens used in the apparatus improves viewability because unwanted reflections from the surfaces of the lens are shifted such that they are no longer visible when viewing the suspended image.

Title: Electrochromic media with concentration-enhanced stability, process for the preparation thereof and use in electrochromic devices
Inventor: THEISTE DAVID A
IPC: G02F1/1503
Filed: 2000-04-28
Abstract: Increased stability of electrochromic devices containing an electrochromic medium having two or more electroactive compounds is accomplished by establishing current limiting concentrations of electroactive compounds with the larger redox potential difference. A process for production of electrochromic devices uses targeted concentrations of electroactive materials during preparation of the electrochromic medium which results in substantially no devices being produced wherein the current is limited by an electroactive compound having a low redox potential difference.

IPC: A47J43/28
Filed: 2001-03-27
Abstract: A set of stirring devices, such as spoons, made of a chromatic material. Each device is sized for a specific use and the temperature change of the material is at a prescribed threshold to correspond with the application of each spoon. The devices or spoons are designed for specific cooking applications. The devices would be used as standard kitchen utensils, as in the example of wooden spoons or spatulas, but change colour when the cooking ingredients reach a preprescribed temperature and thus indicate visually that the key cooking temperature had been reached. This aids in the cooking process and eliminates the need for a cooking thermometer or other test of the cooking stage.
