Title: Imaging system for vehicle headlamp control
Inventor: ROBERTS JOHN K
IPC: G01J1/42
Filed: 1999-06-04
Abstract: An imaging system for use in a vehicle headlamp control system includes an aperture, an image sensor, a red lens blocking red complement light between the aperture and the image sensor, and a red complement lens blocking red light between the aperture and the image sensor. Each lens focuses light onto a different subwindow of the image sensor. The imaging system allows processing and control logic to detect the presence of headlamps on oncoming vehicles and tail lights on vehicles approached from the rear for the purpose of controlling headlamps. A light sampling lens may be used to redirect light rays from an arc spanning above the vehicle to in front of the veicle into substantially horizontal rays. The light sampling lens is imaged by the image sensor to produce an indication of light intensity at various elevations. The processing and control logic uses the light intensity to determine whether headlamps should be fumed on or off. A shutter may be used to protect elements of the imaging system from excessive light exposure.

Title: Dispositif immerge destine a reduire les emissions polluantes et a economiser l'energie dans des moteurs a combustion d'hydrocarbure
Inventor: CHANG SOO KIM BUDDY
IPC: F02M27/06
Filed: 1999-07-26
Abstract: Ce dispositif, immergé dans le réservoir de carburant de véhicules à moteur à combustion interne d'hydrocarbure liquide, qui est destiné à réduire les émissions polluantes et à économiser l'énergie, se caractérise par le fait qu'il génère des champs magnétiques associés à des ondes électromagnétiques d'infrarouge lointain. Ces champs magnétiques et ces ondes électromagnétiques, qui se propagent dans le carburant, interagissent avec les molécules d'hydrocarbure et modifient, de façon temporaire, leur structure. De ce fait, les molécules d'hydrocarbure s'évaporent facilement. On obtient cette modification temporaire de la structure moléculaire des hydrocarbures par excitation desdites molécules par l'énergie dégagée par les rayonnements infrarouges lointains sous l'action des champs magnétiques susmentionnés.

Title: Motorized air-gap optical attenuator
Inventor: BOLDUC SIMON
IPC: G02B6/26
Filed: 2001-02-28
Abstract: A device which allows the controllable attenuation of the signal strength of an optical signal as the optical signal passes through the device. This is done by passing the optical signal through two optical fibers which are separated by an air gap.      The size of the air gap between the fibers controls the attenuation of the signal being passed - the larger the gap, the lesser the amount of optical signal being passed.

Abstract: A brake testing device (100) evaluates the condition of a disk (102) having a disk axis (106) and first and second disk surfaces (108, 110). The device (100) has two gauges (112, 124), each having a sensing element (114, 126) for measuring the position of one of the disk surfaces (108, 110) along a line parallel to the disk axis (106). The gauges (112, 124) generate signals corresponding to the measured positions of the disk surfaces (108, 110). The gauges (112, 124) are secured with respect to each other so as to measure along parallel lines, and are positioned by the device (100) to measure the disk surfaces (108, 110) at points equidistant from the disk axis (106).

Abstract: The present invention discloses a method of interworking between different radio access networks (RAN-A, RAN-B). In this method, a radio transceiver device capable of operating with the first radio access network (RAN-A) and the second radio access network (RAN-B) is attached to the first radio access network (RAN-A).      The method comprises the steps of detecting (S11) a service request, accessing information on conditions for the first and the second radio access network (RAN-A, RAN-B) for giving sufficient support for a service requested by the service request, analysing (S12) whether or not the first radio access network (RAN-A) and the second radio access network (RAN-B) meets the conditions, and initiating a handover (S14) of the radio transceiver device (MS) from the first radio access network (RAN-A) to the second radio access network (RAN-B) if the second radio access network (RAN-B) meets the conditions but the first radio access network (RAN-A) does not. Thus, the method according to the present invention serves to support dual mode mobile stations and networks in such a way that the correct radio access which sufficiently supports a requested service is automatically obtained.
