Title: Paint masking stick and process for applying paint mask
Inventor: VAN TYLE PETER R
IPC: C03C17/00
Filed: 1999-05-20
Abstract: This invention relates to a masking stick tool comprising a tube which houses a solid masking material and through which the solid masking material is advanced, which masking material temporarily masks a surface from paint, varnish or other coatings by applying a temporary masking coating by rubbing an exposed portion of a solid paint masking material directly onto the surface to be masked, and thereafter removing said masking coating onto which paint varnish or other coating has adhered. The invention comprises a novel process of temporarily coating a protected surface from paint by rubbing and shearing off the exposed portion of a paint mask solid onto the surface, thereby depositing a film which may thereafter be painted and subsequently removed by wiping it away with a cloth. The paint mask material may be formed and applied as a crayon, or housed, advanced and applied as one would the contents of a lip balm type dispenser.

Title: Sprinkler head escutcheon locking ring
Inventor: WINEBRENNER THOMAS E
IPC: A62C31/28
Filed: 1999-06-25
Abstract: An escutcheon locking ring for an automatic sprinkler head having an externally threaded section with a top portion having an engaging member extending therefrom comprises a ring having a plurality of tabs extending from the inner perimeter, and an outer perimeter having a plurality of escutcheon engaging fingers depending therefrom. The escutcheon engaging fingers are curved and are formed with sharp ends. When positioned between the bottom surface of the engaging member and the escutcheon, the sharp ends of the depending escutcheon engaging fingers penetrate the surface of the escutcheon. An attempt to unscrew the escutcheon from the sprinkler head causes the rotation of the ring until frictional contact is made between the extending tabs and the engaging member. Once frictional contact is achieved, a positive lock is formed preventing one from unscrewing the escutcheon from the sprinkler head.  In an alternative embodiment, the extending tabs are replaced by extending U-shaped members. The curvature of the depending escutcheon fingers enables the locking ring of the present invention to be formed from a single sheet of material.

IPC: G06N5/04
Filed: 1999-03-11
Abstract: A method and system for reducing the number of cases in a cased based reasoning system that are considered applicable to a current problem for a specific complex apparatus. In addition to a database of previously solved cases, the system has a domain database containing all components that make up a set of apparatus. The system also has a database containing configuration knowledge which defines the components from the domain that are excluded from a specific apparatus. The configuration information is used to filter any cases from consideration as potential solutions if they reference components not in the configuration of the specific apparatus for which the current problem exists. The configuration knowledge is also used to display to the user only the components that make up the specific apparatus for which the current problem exists. The configuration knowledge also includes information on default values for components within the specific apparatus. The default values being used to avoid prompting the user to answer a question for which the value is already known.

Title: System and method for enhanced routing and reservation protocol
Inventor: BEYDA WILLIAM J
IPC: H04L12/56
Filed: 1999-12-13
Abstract: A network node (54, 56, 58 and 60; 130, 132, 134, 136, 138, 140, 142, 144 and 146) and a method of dynamically reconfiguring routes of established connections in a communications system (52;110) operate to provide the optimal path for a new connection based on a priority status of the new connection. The optimal path is provided even when a communication link (36, 38, 40 and 42; 152, 154, 156, 158, 160, 162, 164, 166 and 168) on the optimal path does not have a sufficient amount of available bandwidth to accommodate the new connection. The network node operates in conjunction with other network nodes in the system to reroute one or more established connections that have reserved bandwidth on a communication link on the optimal route and have a lower priority status than the new connection, thereby increasing the available bandwidth on the communication link to accommodate the new connection. The network node also performs conventional functions of a router. The network node and the method can be implemented in any communications system where information is transmitted in packets, blocks, frames or cells. The network node includes a reroute-signal generator (98), a network monitor (96) and a reservation unit (100) that operate with a CPU (94) of the node to perform the rerouting operation.

Patent CA-2305402-A1 (CA)
Title: Battery capacity measurement circuit
Inventor: HSU RUPERT
IPC: G01R31/36
Filed: 1998-09-30
Abstract: An electronic circuit and a method for accurately measuring intermittent current pulses supplied by a storage battery to energize a load. In the preferred embodiment, an analog integrator accumulates current pulses in response to a voltage drop across a sense resistor that is connected in series between the storage battery and the load. The voltage drop is proportional to the flow of current from the battery through the load.  The output of the integrator is filtered with a low pass filter to block high frequency noise, and the output of the filter is coupled to an analog to digital (A/D) converter that transforms the filtered analog signal into a corresponding digital signal. The output of the A/D converter is supplied to a port of a processor. The processor provides a signal to actuate a reset switch coupled across the integrator. When closed at the end of each integration time period, this switch zeroes the output of the analog integrator. Additionally, the processor recalibrates the circuit at predefined time intervals to determine for leakage currents for improving the accuracy with which the measurement of the flow of current from the battery is determined. In the preferred embodiment, the processor samples the output of the A/D converter every 100 milliseconds. Typically, the calibration procedure is performed every 15 minutes (while the load is energized from an AC source). This measurement circuit is part of a battery management system that preferably also includes a charge circuit for recharging the battery.
