Title: A technique for determining a mechanical zero value for a coriolis meter
Inventor: BRUCK ROBERT
IPC: G01F1/84
Filed: 1992-07-02
Granted: 1997-06-10
Abstract: Apparatus and ac-companying methods for inclusion in a Coriolis me-ter (5) that substantially eli-minate temperature in-duced measurement errors which might otherwise be produced by performance differences existing be-tween the separate input channels contained in the meter. Specifically, two pairs of input channels (44, 54, 64) are used in the me-ter. In operation, the meter repetitively measures the internal phase delay of each of these pairs and then subtracts the delay associated with each pair from actual flow based measurement data subsequently obtained therefrom. While one channel pair is measuring actual flow, the other channel pair is measuring its internal phase delay, with the channels being continuously cycled between these functions. Because both channel pairs are cycled at a sufficiently rapid rate, the current value of the internal phase delay for each of the pairs accurately reflects any temperature induced changes then occurring in the performance of that pair thereby eliminating substantially all temperature induced error components from the flow measurement subsequently obtained therefrom.  In addition, the meter measures flow tube temperature in a manner that re-moves temperature induced errors therefrom.  Furthermore, the meter also measures and updates its mechanical zero value using only zero flow .DELTA.t measurements that have a sufficiently low noise content; this mechanical zero value is subsequently subtracted from the flow based measurement data to eliminate errors therein that would otherwise occur.

Title: Process for transmitting or storing over disturbed channels a digitalized, encoded audio signal composed of a series of information blocks
Inventor: WIESE DETLEF
IPC: H04H20/95
Filed: 1992-10-20
Granted: 1999-06-08
Abstract: Digitalized encoded audio signals for transmission over disturbed channels are composed of a series of information blocks made of information units containing various types of information,  such  as  control  information,  scale  factor information and information on encoded scanning values derived from partial-band and/or transformation coding at the source. The units of information concerning the encoded scanning values are allocated to a determined spectral structure.  Before its transmission or storage, the encoded audio signal is subjected to  a  channel  encoding  dependent  on  the  desired  error protection.  When errors are recognized, they are corrected, and when the errors cannot be corrected, they are concealed. For the channel encoding of the units of information concerning the encoded scanning values, a variable bit error protection is provided depending on the allocation of the individual information unit to a determined spectral structure,  i.e., units of information concerning the encoded scanning values of lower frequency audio signal fractions are given a higher bit error protection than units of information concerning the encoded scanning values  of  higher  frequency  audio  signal fractions.  The variable error protection to be selected for the  individual  information  units  is  further  determined depending on the admissible duration and frequency, according to subjective criteria, of the applied error concealment.

Abstract: A lens (10) imposed of a single material and having at least one refractive surface (14) on one face and a kinoform (20) on the other face(16). The pure refraction between the surfaces varies dimensionally and in refractive index in response to temperature changes and thereby-changes characteristics, such as the back focal length, of the lens while the kinoform varies differently in response to the same temperature changes. The kinoform power is sufficient to vary the temperature induced characteristic changes of the lens in an opposing sense at a given wavelength and in an amount sufficient to athermalize the optical device. In one embodiment the kinoform power compensates for the combined temperatureinduced effects upon the refractive portion and any mount that supports the lens:

Title: Lan cable identifier for testing local area network cables
Inventor: LOCKE THOMAS P
IPC: G01R31/02
Filed: 1994-12-13
Granted: 1998-11-24
Abstract: A LAN cable identifier for testing and identifying copper-conductor LAN cables in conjunction with a LAN cable test instrument is provided. Series combinations ofresistors and diodes allow for both resistance measurements and polarity determinations for selected pairs of conductors of the LAN cable. Resistance values are chosen to allow for identification of each combination in order to diagnose wiring errors and to identify the particular LAN cable identifier. In addition, capacitance measurements are accommodated with minimal contribution to measurement error by careful orientation of the resistors and diodes so that the diodes may be reverse biased by a d.c. bias voltage provided by the LAN cable test instrument. The reverse biased diode junctions contribute only a small amount of shunt capacitance to the measurement.

Title: Double detection system
Inventor: LORENZO JOHN L
IPC: G06K13/067
Filed: 1995-04-04
Granted: 2007-02-13
Abstract: The present invention relates to an electro-optical system for double document detection wherein an improved calibration is employed. To calibrate the system, a microcontroller generates a series of increasingly wider pulses, which are transformed into a series of respective increasingly higher ramp pulses to drive a light emitter (LED, a laser diode or fiber optic coupled laser) at gradually increased power until the predetermined value of an output signal of the light detector (photo-transistor) is achieved. Then the pulse width corresponding to the predetermined value of the output signal is fixed. This width becomes the drive for the light emitter until another calibration changes it. The microcontroller (with the software in it) monitors the output signal to determine a double-feed document condition if the output signal exceeds a predetermined value.      The system is capable of "hands-off" calibration. To detect a "true" double-feed document condition, a software timer counts a prolongation of the alteration of the output signal. Also, in order not to miss a "true" double-feed document condition when the area of overlapping is small, the distance between a front edge of the first overlapped document and a rear edge of the last overlapped document is measured. The system also declares a double-feed document condition if a space between two fed documents is no greater than a predetermining value. The system is also capable of self compensating for component variations, component deterioration and voltage variation over time, slight misalignment, and accumulated paper dust, if any. The system also provides a safety circuit to protect the light emitter from excessive power dissipation. If the situation of power down in the system occurs, the recalibration is not needed, since the system is provided with the non-volatile memory to store the fixed width. Each stage of the system is indicated by LEDs.
