Title: Medication Vial/Syringe Liquid/Transfer Apparatus
Inventor: PETERSON STEVEN F
IPC: A61J1/06
Filed: 1996-12-11
Abstract: Liquid-transfer apparatus, and methodology employing the same, operatively interposable a syringe and a vial, and accommodating both a single-mouth-size (single-size), two-vial transfer procedure, and a two-mouth-size (two-size), two-vial transfer procedure. The apparatus includes a liquid-transfer device having a syringe-coupling end, a vial-coupling end, and liquid-passage structure effectively communicating between these ends. In the case of accommodating a single-mouth-size (single-size), two-vial procedure, only the liquid-transfer device is employed, and the same is sized with a vial-coupling end that is constructed for direct coupling to the top of the single-size vial which is used. In the case of accommodating a two-mouth-size (two-size), two-vial operation, the liquid-transfer device is employed along with a vial-coupling adaptor which is removably receivable in a connected relationship with the vial-coupling end in the device to adapt the same for coupling to the top of a vial having the smaller of the two sizes of vials which are to be employed. Under these circumstances, the entire procedure begins with coupling of the apparatus to a syringe and to the smaller-size vial, with the vial-coupling adaptor connected to the liquid-transfer device's vial-coupling end. Following a liquid-transfer operation with this smaller vial, the same is decoupled, and such decoupling automatically disconnects the vial-coupling adaptor and the liquid-transfer device. Thereafter, a vial of the larger size is coupled to the vial-coupling end in the liquid-transfer device, and a transfer procedure is completed between the syringe and the larger coupled vial.

Title: Method and apparatus for drilling with a flexible shaft while using hydraulic assistance
Inventor: SALLWASSER ALAN
IPC: E21B7/06
Filed: 1997-02-19
Abstract: An apparatus and method are disclosed for applying thrust (weight on bit) to a drill bit when drilling with a flexible drilling shaft while creating perforations in a cased well. The thrust is applied directly to the drill bit instead of applying it to the drill bit through the flexible drilling shaft. A support bracket is also in contact with a piston and is in slidable contact with the tool housing. A portion of the piston is positioned inside a chamber in the housing and is slidably attached to the chamber walls. As hydraulic fluid flows into the chamber opposite the piston, the piston is forced toward the drill bit. As the piston moves toward the drill bit, force is exerted on the support bracket whichcauses the bracket to move toward the drill bit. This force is transferred to the drill bit during the drilling process, thereby supplying the force (weight on bit) needed by the drill bit to effectively drill through a desired material.

Patent CA-2203218-A1 (CA)
Inventor: KOHLER JOYLEE E
IPC: H04M3/42
Filed: 1997-04-21
Abstract: An ACD system (101) is programmable by an operator of the ACD system to automatically change the work of a call center agent (106-108) in order to maximize the agent's productivity and to provide a variety of work balanced with"breather" time in order to prevent agent burn-out. The conditions for changing the agent's work and the agent's alternative duties when the conditions are met are both programmed by the operator via a vectoring capability (150) of the ACD system and a scripting language (FIGS. 2-23) for defining the vectors. When an agent becomes available to handle a call from a particular call queue (121-129), the agent's corresponding vector is executed, and the conditions specified by the vector arechecked against the present status of the call center to determine if they are met. If the conditions are not met, the agent is caused to handle a call from the particular call queue. But if the conditions are met, the agent is caused to perform a function specified by the vector, other than handing a call from the particular call queue, even though a call may be waiting for an available agent in that call queue.

Abstract: A demand driven pull-through computerized decision support scheduling system The Cube System - employing a CUBEBOOKING Program operating in near real time to load Jobs (a sequence of predefined process) in Cube Cells at a Workspace in Time defined in a selected Cube World in response to demand place on the Cube World by a customer order, which program allocates the best available resources to produce products (Product Resources) composed of materials (Material Resources on a Positive Bill of Materials) having Features (contained in a Negative Bill of Materials). The Cube System operates to keep track of alternate probable process paths by scoring systems and retains resource usage production history patterns as Prime Data to resolve conflicts between capacity-limited resources (Resource Contentions). The CUBEVIEW Program provides three-dimensional representations of Demand and Supply of Resources (displayed on the z axis) at Workspaces (displayed on the y axis) in Time (displayed on the x axis) by a series of Cube Views, and displays Resource contentions, the presence of which requires user intervention to rotate the cube display to examine the z, y axis (Resources, z, on the horizontal axis; Workspaces y, again on the vertical axis, at time = 0, a given Time Cell) for contentions. Using the view the system recommends alternative reallocation of Resources to other Workspaces to eliminate Resource Contentions in the various Cube Cells.

Abstract: The present invention is an optical monitoring and test access interconnection module especially adapted for use with a fiber optic distribution frame for a fiber optic communications system. The interconnection module provides a combination of monitoring and test access for two fiber lines, typically a transmit/receive pair, where wavelength division multiplexer (WDM) test access is provided to both the transmit and receive fibers. In one embodiment of the present invention, the interconnection module monitors only the receive fiber line where a power monitoring circuit receives a monitor level optical signal via an optical tap and converts the optical signal to an electrical output: Processing electronics and firmware within the module are operable to generate alarms and other control signals when changes in the power level of the received signal are detected. A test access path is provided on the module for use, for example, with an optical time domain reflectometer (OTDR). In one embodiment of the present invention, the interconnection module incorporates a unique physical design arrangement that separates the optical signal processing from the electronic processing into partitioned sub-modules. The optical and electronic sub-modules may advantageously be assembled (and dis-assembled) by means of guides that allow the module halves to slide together. A unique optical mating connector is provided in the sliding arrangement to join the optical module to an opto-electronic photodetector in the electronic module.
Patent CA-2214839-A1 (CA)
Title: Broadband switching system
Inventor: ADAMS JOHN LEONARD
IPC: H04L12/54
Filed: 1996-03-08
Abstract: In a broadband switching system for the switching of asynchronously transferred cells of data, a dynamic bandwidth controller (DBC) controls the application of data cells to an input port of the system, the data cells being supplied by a number of transmitting end-systems. When an end-system begins transmitting data cells, the DBC  detects the presence of incoming cells and requests bandwidth from a connection admission control (CAC) forming part of the system. The switching system stores a table associating a number of signal sources connected to the input port with respective predetermined maximum transmission times and maximum transmission rates for the sources. When arrival of cells at the input port from one of the source is detected, the DBC and CAC operate together to allocate sufficient bandwidth in the switching system to allow the respective message size to be transmitted within the respective maximum transmission time.  A guaranteed minimum rate of transmission is also guaranteed for the source.

Title: System and method of locating a mobile terminal within the service area of a cellular telecommunication system
Inventor: DUFOUR DANIEL
IPC: H04W64/00
Filed: 1996-03-01
Abstract: A mobile terminal locator for locating a mobile terminal (24) in a cellular telecommunication system (10) identifies a plurality of candidate handoff cells (22, 23) having sufficient signal strength to maintain a call and forces sequential handoffs of the mobile terminal (24) from its serving cell (21) to the plurality of candidate handoff cells (22, 23). The locator then measures signal strength and propagation delay between the mobile terminal (24) and the base stations. Either the signal strength, the propagation delay, or both are then used to calculate a distance between the mobile terminal (24) and each base station associated with each of the plurality of candidate handoff cells (22, 23) and between the mobile terminal (24) and its serving base station (21). From the calculated distances, a plurality of arcs of possible locations (26, 29, 30) of said mobile terminal are then defined. Finally the mobile terminal locator calculates an intersection point of the plurality of arcs of possible locations (26, 29, 30), defining the location of the mobile station (24). The locator may operate in cellular telecommunication systems with or without synchronized timing reference signals from the base stations.
