Title: Method of Using a Narrowband Server to Provide Service Features to Broadband Subscribers
Inventor: KOS RICHARD JAMES
IPC: H04L12/56
Filed: 1997-02-10
Abstract: A method for providing narrowband-related service features to subscribing broadband lines comprises establishing a composite voice path interconnecting a narrowband server and the subscribing broadband line via a broadband switching fabric. Particularly, a call set-up signal is received in a broadband call processor, converted to narrowband signaling format and extended to a designated narrowband server. Responsive to receipt of the call set-up signal, the designated narrowband server establishes a narrowband voice path interconnecting a narrowband network element to a synchronous-asynchronous converter. Subsequently, the broadband call processor establishes a broadband segment interconnecting the subscribing broadband line with the synchronous-asynchronous converter. The broadband segment corresponds to the narrowband voice path to form a composite voice path. The composite voice path is used by the designated narrowband server to provide narrowband-related service features to the subscribing broadband line. After a call in which narrowband-related features may be invoked has been disconnected, the composite voice path is released.
Patent CA-2197404-A1 (CA)
Inventor: DUHON PETER A
IPC: E21B23/06
Filed: 1997-02-12
Abstract: A fluid loss device  has  a housing,  a  seal  assembly,  a running tool, and a plug.  The housing of the fluid loss device is  placed  in  a  production  string  before  a  well  bore  is completed.   The plug is attached to the running tool,  and the running tool is attached to a wash pipe.    The fluid loss device is activated by lifting the wash pipe and the running tool,  thereby engaging the plug with the seal assembly,  engaging  the  seal  assembly  with  the  housing,  and severing the plug from the running tool.   Activation of the fluid loss device inhibits fluid communication through the fluid loss device and reduces damage to the well structure behind the fluid loss device while completion operations are performed in other areas of the well bore.    The fluid loss device is deactivated by forcing the plug through the fluid loss device with mechanical force or pressure, or by chemically eroding the diameter of the plug until the plug passes  through the  fluid  loss  device.   Once  the  fluid  loss device is deactivated,  the isolated area of the well bore is reopened for access through the production string.

Abstract: A method for standardizing a spectrometer generating an optical spectrum from a sample, comprising generating at least one optical spectrum from at least one standardization sample each having a chemical composition resulting in the optical spectrum showing a characteristic pattern in a predetermined frequency range, comparing information relating to the pattern(s) to corresponding information relating to at least one reference pattern previously defined as the desired standard response from the at least one standardization sample, determining, based on the comparison, standardizing parameters describing the transition of the pattern(s) of the generated spectrum or spectra to the reference pattern(s) and storing said standardizing parameters in the spectrometer or a computer connected thereto, so that the spectrometer, when presented to an unknown sample, will, using the standardization parameters, generate an optical spectrum substantially identical to that which would be generated in a corresponding spectrometer standardized with a sample of the same chemical composition using the same previously defined reference pattern(s). The present method relates to standardization of the instrument to a well-defined state into which any number of instruments may be brought. In this state, calibrations may be transferred freely from instrument to instrument.
Patent CA-2216122-A1 (CA)
Title: Electronic control unit and method for fuel delivery
Inventor: CUTLER DAVID K
IPC: F02D41/34
Filed: 1996-02-23
Abstract: A method and apparatus are disclosed for controlling the operation of a fuelinjected, spark-ignited internal combustion engine by adjusting the pulse width of the fuel injection signal. An initial fuel injection pulse is set (ECU) for respective, preselected pairs of engine operating parameters such as engine speed (38) and manifold pressure (24). The injection pulse width is then adjusted by a computer control (ECU) for each preselected pair of parameters to obtain optimum performance for example, as might be indicated by detection of engine torque. Each time a pulse width is adjusted (ECU), all previously adjusted pulse widths are compared (ECU) with respect to corresponding pulse widths in stored-template fuel maps (ECU). The bestmatched template fuel map is then used in conjunction with all previoulsy adjusted points to create a new operational fuel map (ECU) to run the engine until a more updated operational fuel map can be created upon additional fuel pulse widths being tuned.
Patent CA-2216144-A1 (CA)
Title: Absorbent articles having improved surfactant-treated hydrophilic topsheets
Inventor: LEE YANN-PER
IPC: A61F13/511
Filed: 1996-03-20
Abstract: The present invention provides an absorbent article having a topsheet treated with a silicone-based surfactant to impart hydrophilicity. The absorbent article preferably includes a first, apertured, macroscopically expanded, three-dimensional, polymeric topsheet and preferably includes a second, apertured, macroscopically expanded, three-dimensional polymeric topsheet underlying the first topsheet. The multiple topsheets provide improved masking of bodily fluids absorbed and retained by the absorbent core. The first and second topsheets preferably include surfactants which impart hydrophilicity to differing degrees, and which preferably are selected from diverse surfactant categories. The use of a silicone-based surfactant imparts improved tactile qualities to the wearer-contacting surface of the first topsheet in comparison with non-silicone-based surfactants. These characteristics of the silicone-based surfactant provide improved dryness and cleanliness of appearance through low retention of fluid material at or near the surface of the topsheet itself and promoting fluid movement along the wetted surfaces and downward into the absorbent core.
