Title: Query supporting interface between a customer administrative system and database network elements of a telecommunications system
Inventor: GLITHO ROCH
IPC: H04Q7/24
Filed: 1998-11-20
Abstract: A customer administrative system (24) of a wireless communications system (20) is interfaced (22) with one or more system database network elements (26) to support not only transaction oriented (28) communications, but also query oriented (30) communications. Logic is included in the interface to process (42) and translate (48) search request queries (40) for database network element handling. Results of any searches performed in response to the queries are returned to the interface. The logic then collects the information comprising the results of the searches, and supports file transfer of the collected information to the requesting customer administrative system.
Patent CA-2315845-A1 (CA)
Inventor: PHILLIPS ROGER W
IPC: C09C1/62
Filed: 1998-11-09
Abstract: A rigid and brittle bright metal flake is formed of a central layer of a reflective material supported on both sides by dielectric layers. In a preferred embodiment, the metal layer is aluminum having a thickness of about 100 nm and the dielectrics are either silicon dioxide or magnesium fluoride, each having a thickness of about 100 nm. The result is a very thin three-layered metal flake about 300 nm thick that exhibits a uniaxial compressive strenght of about 8 times a corresponding uniaxial tensile strength. As a result, the metal flake is then afforded the benefits of rigidity and brittle fracture during the manufacturing and applicational processes which ultimately provides favorable planar and specular reflectance characteristics in the visible wavelength range.

Title: Flicker filter and interlacer implemented in a television system displaying network application data
Inventor: BRIL VLAD
IPC: H04N5/44
Filed: 1998-12-14
Abstract: A television system (100) with an in-terlaced display screen for displaying net-work application data. A flicker filter (480) is preferably implemented as an infinite im-pulse response (IIR) filter to eliminate sharp transitions in the network application data images. A random access memory (RAM) is used to store the lines of the filtered im-ages and any adjacent lines used for the fil-tering operation. Alternate lines of the fil-tered images are retrieved from the RAM to provide an interlaced image of the filtered network application data images. The inter-laced images are displayed on an interlaced display unit of a television system.

Title: Vehicle guidance and switching via magnetic forces
Inventor: BUSHKO DARIUSZ A
IPC: B60L13/06
Filed: 1998-12-23
Abstract: A system for guidance and/or switching of a vehicle (100) or other object comprises a guideway (110), a guide plate (108) that moves along the guideway (110), and a magnetic field source that induces a magnetic force between the guide plate (108) and at least a portion of the guideway (110) over which the guide plate (108) is moving. The guide plate (108) is attached to the vehicle (100) or coupled to its steering systems. The magnetic force centers the guide plate (108) along the guideways (110) by opposing any lateral deviation from center. The magnetic field source is a permanent magnet, an electromagnet (including a superconducting magnet) or any other known magnetic field source. It is preferably included in, or forms part of, the guide plate (108). Likewise, the guide rail preferably comprises ferromagnetic or paramagnetic material, i.e., a material that forms a temporary magnet in the presence of the magnetic field of the source. Thus, for example, one aspect of the invention provides a system of vehicle guidance in which the guide plate (108) comprises an arrangement of permanent magnets that slide over a ferromagnetic, e.g., steel, guideway rail.

Title: Improved school bus door operator
Inventor: SEYMORE MARK A
IPC: E05F11/10
Filed: 2000-08-29
Abstract: An improved school bus door operator for a school bus, or other public transportation vehicle or bus. The improved school bus door operator of this invention consists of a linear actuated school bus door operator with a handle for operation by the driver and the linkage tying the operator to the school bus door. The linear actuated school bus door operator allows the driver of the school bus to open and close the school bus door with a back and forth short-stroke linear movement of the handle. This should reduce repetitive stress injuries which school bus drivers have occasioned. The improved school bus door operator generally consists of a handle slide mechanism, a rotatable pivot arm, and a door linkage arm engaged to the school bus door. The handle slide mechanism further consists of a slide arm that may be moved linearly within the handle slide mechanism. The slide arm has a handle that juts out generally in a vertical direction at a rearward portion of the slide arm. At an opposite end of the slide arm from where the handle is engaged is an engagement pawl. The engagement bolt also rises from the slide arm in a generally vertical direction. The rotatable pivot arm has two guide rails or a through-slot. The engagement bolt of the slide arm fits between the guide rails or through-slot of the rotatable pivot arm. The rotatable pivot arm has a pivot bolt, which allows the pivot arm to rotate on the dash or other mounting surface in the school bus.

Inventor: WORTHY DAVID G
IPC: H04H1/00
Filed: 1999-02-16
Abstract: A bias compensating remote audience survey system (34) is configured to identify radio stations (162) to which tuners (24) are tuned. The tuners (24) have predetermined signals (26) emitted therefrom. The survey system (34) employs a method (152) of compensating for a station bias, or preference, toward or against one or more radio stations (162). The method (152) includes measuring durations (62) over which the predetermined signals (26) are received by the survey system (34). The durations (62) are then combined by averaging to form a station average detection length (ADL) value (74) specific to one of the radio stations (162). The station ADL value (74) is compared to a multi-station ADL parameter (86). A sensitivity level (146) for the one radio station (162) is adjusted in response to the comparison to compensate for station bias.

IPC: G01R19/165
Filed: 2001-03-12
Abstract: A line card circuit to prevent false off-hook signals resulting from the permanent loss of battery voltage at a line card. In the battery present condition, the 5V operating voltage is connected to the collector lead of an NPN transistor, which also supplies the output signal of the system. The emitter lead of the transistor is connected to ground. The -48V battery voltage is connected to the transistor base lead and biases the base negative with respect to the emitter, maintaining the 5V logic "1" output signal on the collector lead. There is a resistor and capacitor in series, forming an RC circuit, across the 5V collector lead and the -48V base lead. In the battery present condition, there is a significant charge across the capacitor. In the battery absent condition, the -48V battery voltage is lost and the voltage on the base lead rises to a positive voltage in a time interval governed by the discharge time of the RC circuit, thus causing the system output signal to drop to logic "0".
