Inventor: FOX DAVID A
IPC: H02P9/30
Filed: 1989-12-11
Abstract: ABSTRACT OF THE DISCLOSURE A method of regulating the output voltage of an electric power source combines a status signal representa-tive of the output voltage of the power source with a reference  signal  to produce a first control  signal.  A status signal representative of the output current of the power  source  is combined with the reference signal  to produce a second control signal.  A bias voltage signal is applied to  a  junction point  and  the first and second control signals are connected through an OR network to the junction point,  thereby forming an output signal at the junction point.  The power source output is then controlled in response to this output signal.  Under normal operating conditions, the magnitude of the control signal correspond-ing to the power source output voltage is less than the magnitude of the bias voltage signal, and the magnitude of the control  signal  representative of current is greater than the magnitude of the bias voltage signal, such that the voltage sensing loop is in control of the power source output.

In another aspect of the invention, a guiding sheath assembly is provided which permits catheter exchanges involving such small diameter catheters having integral gadders.  In one protocol such a catheter may be exchanged for a conventional balloon dilatation catheter with a movable guidewire by removing the dilatation catheter, advancing the sheath over the guidewire, then removing the guidewire and inserting the replacement catheter.  Similarly, a catheter having an integral guidewire may be exchanged for a similar catheter by first removing the luer fitting at the proximal end of the catheter, then attaching a wire extension to the proximal end of the AZB/dmc catheter, then advancing a sheath over the extension and catheter to locate the distal end of the sheath in proximity to the stenosis, then removing the catheter through the sheath and replacing that catheter with a new catheter inserted through the sheath.

Title: Wireline transmission method and apparatus
Inventor: BYERS TERRY B
IPC: E21B47/12
Filed: 1990-02-06
Abstract: WIRELINE TRANSMISSION METHOD        AND APPARATUS           ABSTRACT OF THE DISCLOSURE          In a wireline data transmission system for passing data between downhole and surface locations in a wellbore, a system for transmitting data at a frequency above the relatively low roll off frequency of a wireline permits higher data rates to be transmitted over the wireline than would be possible using standard digital data formats.  The present system utilizes short duration pulses which are placed on the wireline in conformity to the transition edge between voltage levels in a typical digital data format, and thus transmits the digital data over the wireline in a manner which is not adversely affected by the phase shifting which normally occurs when bi-level voltage data formats are used for data transmission over a wireline.  The short duration pulses are placed on the wireline at a time position in a data format that corresponds to the beginning of a bit period and the pulse width is such that it only occupies a fraction of the bit period so that any phase shifting on the pulse does not shift the pulse into a succeeding bit period to thereby adversely affect data interpretation.

Title: Electronic watthour meter
Inventor: GERMER WARREN R
IPC: G01R22/00
Filed: 1990-04-19
Abstract: ABSTRACT OF THE DISCLOSURE      An electronic watthour meter is digitally configurable to operate as several different types of watthour meters for metering electrical energy from a variety of different electric utility services.  Automatic scaling of line input currents is provided to scale the voltage input to an analog to digital converter over selected ranges such that low level and high level input signals are measured in an optimum range.  A digital signal processor is employed to calculate values for metered electrical energy and output pulses, each proportional to a quantum of energy flowing in the circuit being metered.  The processor calculates the value of DC offset errors inherent in the various analog circuits of the meter and uses that value in the calculation of metered electrical energy to compensate for such offset errors. The meter employs automatic and manually initiated test functions for testing the operation of the processor and other critical circuits in the meter.

Title: Electronic accident estimating system
Inventor: CARBONE DOMINIC
IPC: H04N19/00
Filed: 1990-09-12
Abstract: Abstract An Electronic Accident Estimating System has been produced by integrating  commercially  available  electronic hardware  with proprietary software developed expressly for the estimating system.          Electronic images of accidented vehicles are taken by the bodyshop estimator.  These images are then imported to a computer by using a color video digitizer.  The images, once resident in the computer, provide the visual evidence substantiating the estimated accident damage.  The bodyshop estimator fills in the accident estimate on the computer, highlighting areas on the various images as required.          Once the estimate is completed, the estimate file is compressed in size and transmitted electronically to the insurance company.  At the insurance company, an insurance estimator then decompresses the estimate  file and  begins  to  peruse  the  estimate.    If  further clarification is required, the insurance estimator can request more images to be taken and transmitted. Execution of repairs can also be easily audited by the insurance company by simply requesting that  images  be  taken  during  the  repairs  at  specific  repair milestones  (  replacement of body panels,  application of primer, etc. ) and transmitted to their office.  The system also provides on-line archiving of accident estimates.
