Title: Improved coaxial cable protection device
Inventor: VOKEY DAVID E
IPC: H04B3/54
Filed: 2000-02-09
Abstract: A coaxial drop cable safety device is used for cable television, data and telephony applications. The device is used on buried drop cable where 60 Hz powering voltages applied to the drop cable exceed low voltage safety limits and where the drop cable is buried at depths which is less than the minimum required to meet electrical safety codes. Tap end and premise end units are connected to the drop cable. The tap end unit applies a DC voltage to the centre conductor of the drop cable. A monitoring circuit in the tap end unit monitors the DC current in the centre conductor. The tap unit will immediately remove the powering voltage In the event of either an open or faulted condition on the centre conductor along the entire length of the drop cable. Additionally, while providing fault protection for the low frequency powering circuit due to tampering or damage to the cable, the fault monitoring circuit allows the high frequency television, data and telephony signals to pass with little or no impediment.

Abstract: The Wristthotic Chariot (also referred to as the invention) is a device designed to relieve the discomfort of Carpal Tunnel Syndrome and wrist/arm Repetitive Strain Injury (RSI) often caused by the utilization of the computer mouse. The invention is attached to an existing mouse's upper surface in the fashion similar to that of a chariot or buggy attached to a vehicle. The invention raises or elevates the wrist while the wrist is resting upon the invention's foam/plastic support, which is elevated to a height of 1/8 inches to 3 inches (0.5 to 8 centimeters) while laying on a flat surface. The invention moves in tandem with the mouse unlike prior art/conventional wrist rests/wrist bars that remain static. Such attachment of the invention to the mouse ensures the wrist remains in a more constant fixed position as the mouse is guided and maneuvered by the user.

Title: Apparatus and method for laser welding in a hemmer apparatus
Inventor: BUSUTTIL PETER L
IPC: B23K26/20
Filed: 2000-04-25
Abstract: A hemmer apparatus has at least one welding laser attached to the moveable crown for controlled welding of the hemmed panels to hold the panels with respect to one another, at least temporarily, and/or to maintain geometry between the panels until permanently fixed, such as when the adhesive cures or when additional welding is performed. Laser welding in the hemmer apparatus can be performed by providing relief in the steel used to form the hem, or by providing a tab in the hem material extending beyond the steel forming the hem, or a combination of the two, in order to allow access of the laser beam to the location where the geometry stabilizing tack weld is desired to be placed. Multiple welds are placed in spaced locations about the periphery of the hemmed panels as required for the specific application.
Patent CA-2312597-A1 (CA)
Inventor: ZHANG BENJAMIN
IPC: G06F40/143
Filed: 2000-07-05
Abstract: The present invention provides a technique by which complex queries can be defined and executed in a very flexible and efficient manner. It allows user to define the relationships between a parent and its different children, which can be nested to n-depth levels. The relationships are mapped to a special tree structure and the query processor executes the query based on the tree in an efficient way. The output data is also constructed in the defined tree structure in XML  by default, which eliminates data redundancy. The output can be formatted either in Extensible Markup Language (XML) or HyperText Markup Language (HTML) format.   The present invention also provides two mechanisms to allow user to define the query: either through configuration files or through a graphical user interface. It is designed in such a way that it can be easily implemented as stand-alone application, for batch processing, or interacting with other applications. The query processing module and the graphical user interface modules are written in the Java programming language and the Java Database Connectivity (JDBC) technologies.   The technique of data retrieval disclosed in this invention is different from existing techniques in its high degree of flexibility and complexity in terms of the query structure, yet efficient processing and accurate output result. Because the output is also in tree structure, it eliminates data redundancy and more readable. Furthermore, it is designed as generic as possible and can be used for any data retrieval as long as a tree structure can be defined among the tables or nodes. It can be used in a wide range of systems for database publishing, content management, supply chain management (CRM), electronic data interchange (EDI), and other e-business applications and middleware.

Abstract: Apparatus for treatment by radiotherapy, comprises a patient table, a directional radiation source directed generally toward the patient table, the table and source being movable relative to each other at least axially with respect to the table and rotationally around the axis, the source being directionally adjustable within at least a plane including the longitudinal axis of the table, and including means to correlate axial relative motion of the table and directional adjustment of the source. Thus, the source of such an apparatus can be rotated about the table to access the predetermined position along a series of cones centred on the predetermined position and of the variable angle.  Thus, the apparatus effectively accesses the predetermined position via lines of latitude rather than longitude. It is preferred if the source is directionally adjustable across an included angle of at least 20°  preferably more than 30°. The source can be (for example) held within a ring member centred substantially on the patient table.

Abstract: In a telecommunication network, an ATM Adaptation Layer (2) (AAL2) signaling protocol is employed independent of the signaling bearer service being used in transport signaling messages to and from various network entities, such as mobile switching centers, radio network controllers and cell base stations in, for example, a mobile telecommunications network. This is achieved by dividing the functionality of the AAL2 signaling protocol into a number of functional sublayers including an AAL2 Signaling Common Part (CAP), a Bearer Coordination Part (BCP) and a Bearer Adaptor Part (BAP), wherein the BAP adjusts incoming and outgoing messages so that they are compatible with the AAL2 signaling protocol or the underlying signaling bearer service respectively.

Abstract: A system and method for automatically reconfiguring a multi-mode transceiver in a mobile telecommunications system for adapting to changes in traffic for two or more modes of operation.  Upon receiving a request (202, 302) to set up a communication channel having a digital or analog mode of operation and determining (204, 304) that the said channels are available, an idle transceiver (206, 306) operating under an alternate mode of operation is automatically reconfigured (214, 310) to operate in the requested mode so as to provide the requested communications channel. In the alternative, historical traffic statistics are stored and are used by a traffic estimator (50) for periodically calculating an optimal distribution between analog and digital transceivers. The optimal distribution for maximizing system resource utilization and revenue is implemented by reconfiguring the multi-mode transceivers in accordance with the calculated distribution.
