Title: Arc lamp ballast
Inventor: BRATES NANU
IPC: H05B41/24
Filed: 2000-01-13
Abstract: A ballast for a mercury-free, metal halide arc lamp having a quartz or fused silica envelope.

Title: Program signal blocking system
Inventor: FORLER JOSEPH WAYNE
IPC: H04N21/488
Filed: 1997-12-18
Abstract: An apparatus and a method for preventing a user from bypassing a viewer blocking system that uses program related information, such as content ratings, included in a program signal. The present invention prevents the user from exploiting the time delay associated with detecting, decoding and comparing the program related information by switching channels to observe portions of objectionable programs before the blocking system can react. The present apparatus comprises a processor (110) which provides an output signal (RGB OUT) derived from a selected program signal (VIDEO, VIDEO IN, AUDIO IN) of a selected signal channel and prevents or allows user access to the output signal in response to a determination of whether a user selected program blocking criteria is met. The processor modifies the output of a selected program signal upon user selection of a new signal channel if a default blocking mode is selected by the user, then continues to modify the program signal associated with the newly selected signal channel at least until the program related information is determined.

Abstract: A public telephone service tool is formed from a flat plate and includes a slot for receiving locking hooks of an upper housing of the telephone. A hook carried on one side of the tool body lies along a longitudinal axis with a projection carried on the same side for locking the upper housing to a slot within the body and hooking the tool into an aperture of a locking rail of the lower housing which causes the projection to rotate about the hook and be biased against the locking rail to secure the upper housing to the lower housing in an opened position for servicing the telephone. In addition, a T-key is formed as part of the tool body for use in unlocking the upper housing prior to removal from a lower housing of the telephone.
Patent CA-2327750-A1 (CA)
Inventor: LEGER GERMAIN
IPC: G06F17/12
Filed: 2000-12-07
Abstract: The present invention discloses a method and a system for real-time reconstruction of tomographic images from projection data-generated by computed tomography scanners. The method is based on the theory of pseudo-inverse matrices applied to tomographic image reconstruction, and it allows immediate, projection-by-projection or event-by-event updating of the reconstructed tomographic image at the moment the measuring instrument supplies additional individual projection data. The data processing involves simple arithmetic, which can be implemented into general-purpose computers in the first case, and digital signal processors, dedicated programmable logic devices or application specific circuits in the second case. Models of the underlying physical processes, such as the photon emission and detection processes or the spatially variant system response, can be easily included into image reconstruction through the system matrix. Corrections for other physical and instrumental factors affecting the accuracy of projection data, such as attenuation in the body or detector efficiency normalization, can be merged with the pseudo-inverted and regularized system matrix beforehand or be performed "on the fly" by simple multiplication of the matrix elements, thus achieving optimal compression. Real-time updating of the reconstructed tomographic image can be performed as soon as measured projection data become available. No storage of the measured raw data in the form of list mode events or sinogram is required, and the user of the tomographic system may choose to store reconstructed images only, thus achieving optimal compression of the tomographic data.

Abstract: The automatic parking apparatus is configured to provide a solution to the car-parking problems on a global scale. The underground of city streets, highways, airport runways, recreation parks and the like, is excavated to provide conveniently located parking space, at low cost "the virtual conquering of space". A car parking credit card provides data about the drivers' identity, and also the vehicles' particulars to configure a linear robot having tow complementary shuttles operating in symbiosis.      Contemporary handheld communicators provide access to parking availability via satellite and the Internet, of number of parks, specific vehicle parking costs and alternative location maps. A street-side car parking credit card booth and a front video camera on a gate, provide the particular data required, once a parking request is entered and approved. Otherwise the gate remains closed and the driver is instructed to exit into the street traffic. After having been approved for parking the vehicle is driven into an indexed position where the driver shuts the ignition off and exits with the other occupants. Robot linear shuttle A comes over, inspects the vehicle, lifts it by the tires and places the vehicle on shuttle B at ground level which grips the tires firmly in position then proceeds at fast speed towards a computer allocated parking booth, after shuttle A returns to its original standby position. Shuttle B has the ability to move along the X, Y, Z axis engaged by a single encoded electric servomotor to linear gear steel tracks and to index with multi level vehicle parking booths on a modular metallic frame, according to computer program allocation for parking and retrieval of the vehicles and to issue a parking receipt to the driver with the particulars. On request for retrieving a vehicle by the drivers' credit card and password, shuttle B indexes with the particular vehicles' booth once again retrieves the vehicle, clamps the tires firmly in position and proceeds at fast speed to the surface indexed position.     Once again shuttle A comes over retrieves the vehicle and now places it over a car-out indexed position then returns to its standby position. Now the driver opens the door, turns the ignition key-on and drives away. Accordingly, the embodiments of the present invention provide a simple solution to the present and future parking problems, a legacy to society and prosperity worldwide.
