Title: Rotating field eddy current inspection device
Inventor: GUTZVILLER J E
IPC: G01N27/90
Filed: 1993-06-29
Abstract: ABSTRACT OF THE DISCLOSURE          A rotating field eddy current inspection device comprises a transmit coil having a plurality of transmit windings.  A coil form supports the transmit windings in a circumferential arrangement having an axial dimension, each transmit winding extending around the circum-ferential arrangement and having a plurality of axial segments extending along at least part of the axial dimension.  A receive coil having at least one receive winding extends around the circumferential arrangement and a circuit is connected to each of the transmit windings for applying an electrical alternating signal to each transmit winding that is out of phase from each other  transmit  winding  to  produce  a  rotating  and alternating magnetic field around the circumferential arrangement.   The field is applicable to conductive material to  be  testing  around  the  circumferential arrangement to produce eddy currents in the material. An eddy current measuring circuit is connected to the receive winding.   The receive winding receives the rotating  alternating  magnetic  field  from  the  eddy currents of the material to produce eddy currents in the receive coil that are measured by the eddy current measuring circuit.

Title: Process for transferring foils onto permanent substrates
Inventor: KEPPELER MANFRED
IPC: B44C1/17
Filed: 1992-10-19
Abstract: ABSTRACT OF THE DISCLOSURE      Patterns are applied on a foil by a printing or photocopying process and the thus obtained composition is transferred onto permanent substrates made of various materials.  The use of thin, soluble or porous foils allows the modifications required for each application to be obtained.  Foil base materials and solvents are provided whose combination increases the solubility of the foil above that of the applied inks or toner.  The solubility gap between the foil and the toners/inks is further enlarged by the use of porous and particularly thin foils.  This process allows all kinds of patterns to be transferred onto any sufficiently solid surface; the edge of the foil is barely perceptible and adherence is very strong.  The disclosed process and foils are particularly useful for transferring patterns generated by colour or laser photocopiers and in at least one variation are environmentally and occupationally safe.

Title: Bridge-tap equalizer method and apparatus
Inventor: NABORS DAVID H
IPC: H04B3/04
Filed: 1994-06-01
Abstract: An equalizer (100) is suitable for removing the delay distortion from a switched digital signal received from a telephone channel where the delay distortion is caused by a bridge-tap connected to the telephone channel. The equalizer includes a feedback delay circuit (200) which is arranged to delay the output signal (150) by an amount of time based on the square of the predominant frequency of the output signal. The resulting delayed feedback signal (130) is then combined with the input signal, thereby compensating for the delay distortion. The equalizer also includes an amplifier (103) which may be adjusted to compensate to the attenuation distortion caused by the bridge tap.

Title: Method and apparatus for delivering defibrillation shocks with improved effectiveness

IPC: A61N1/39
Filed: 1995-02-09
Abstract: A method for defibrillating a patient's heart with an implantable defibrillator having defibrillation synchronized to the fibrillation waveform is disclosed. The defibrillator is used to detect fibrillation in a patient's heart, monitor at least one far-field fibrillation voltage across two spaced-apart electrodes while the high voltage capacitors are charging, then deliver a high energy shock during a period of ventricular fibrillation when the absolute values of the peak and trough voltages exceed a threshold based on a desired percentage greater than a running average of the absolute values of the peaks and troughs of the fibrillation voltages monitored during and after capacitor charging. The shock is then delivered synchronous with the next significant cardiac complex. The defibrillator also includes a safety timer so that if the threshold is not reached within a specified safe time limit, the high energy shock will be delivered without further delay.

Abstract: A method of generating a threshold array made up of a plura-lity of dot profiles, each of which is made up of a plurality of black or white pixels, certain of the pixels in certain of the dot profiles being constrained to be either black or white.
