Title: Rate of change detection
Inventor: BOUT BERNARDUS J
IPC: G08B17/06
Filed: 1979-04-30
Granted: 1983-01-25
Abstract: ABSTRACT     A method and apparatus is provided for monitoring the rate of change of a signal.  This is achieved by periodically sampling a first signal and generating a reference signal which for each period of sampling is off-set from the first signal by a predetermined amount to form the step-signal.  The first signal and step-signal are compared and if their amplitudes are the same an output signal is generated.  This means that if the first signal changes by a rate in excess of a predetermined rate the output signal is produced.          The method and apparatus thus respond to a predetermined rate of change although the values of the signals vary generally over a period of time.  A particular applica-tion is smoke detection where gradually changes of atmosphere are ignored but a rapid rate of change is detected and the output (an alarm) signal is generated.

Abstract: POWER TRANSMISSION CONTROL  FOR A PULL-TYPE IMPLEMENT         Abstract of the Disclosure A pull-type forage harvester has a feed roll transmission shiftable between forward, reverse and neutral modes by means of a pair of identical single-acting hydraulic cylinders connected symmetrically to the rockshaft of a shifting fork and controlled through a solenoid-operated valve controlled electrically from the operator's station of the pulling tractor.  Hydraulic connec-tions are such that after completion of shifting from one trans-mission output mode to another, both hydraulic cylinders are open to a common hydraulic return line.  However, inadvertent change of pressure in the return line will not cause shifting of the feed roll transmission as, due to the equal size of the hydraulic cylinders and the symmetrical arrangement of the cylinders with relation to the transmission shifter rockshaft, the shifting effort applied to the rockshaft by the respective cylinders would be equal but opposite, resulting in zero net shifting effort.

Abstract: 1          MOGAB, C.J. 4 DEVICE FABRICATION BY PLASMA ETCHING       WITH LESSENED LOADING EFFECT      Abstract of the Disclosure Plasma etching as applied to many of the materials encountered in the fabrication of LSI's is complicated by loading effect-the dependence of etch rate on the integrated surface area to be etched. This problem is alleviated by appropriate choice of etchant and etching conditions.  Appropriate choice of system parameters, generally most concerned with the inherent lifetime of etchant species, may also result in improvement of etch rate uniformity on a wafer-by-wafer basis.  In accordance with this invention this is accomplished by selecting a gaseous matter so that a primary etchant species, which causes the etching by reaction with the surface being etched, has a mean inherent lifetime within the plasma which is no more than one tenth as great as the mean lifetime due to chemical reaction with the surface resulting in etching.

Abstract: A METHOD AND APPARATUS FOR TRANSACTION AND IDENTITY VERIFICATION                      ABSTRACT            A method and apparatus whereby the senders and receivers of messages sent over a transmission system including a Host CPU may guarantee the integrity of the data content of the message and also the absolute identity of the sender.  Each user of the system as well as the Host CPU contains an identical key-controlled block-cipher cryptographic device with data chaining for en-crypting and decrypting messages as required, wherein each user has knowledge of only his own cryptographic key and wherein the Host CPU has access to the unique cryptographic keys of all users of the system stored in a high security storage area available only to said CPU.  Stated very generally, the originator of a message A sends a message to a receiver B which includes a trans-action or message portion X and a unique digital signature portion Y which is a function both of the message and the senders unique cryptographic key KA.  The receiver then communicates with the CPU for verification of the signature Y.  The CPU accesses the sender's key KA from a secure memory and computes the digital signature Y utilizing the message portion X received from B and the key KA.  Upon a successful verification of the signatures by the CPU, the CPU notifies B via an additional message that the signature of A is valid based on the data content of the message and the key KA.  Based on the information received from the CPU, B may be certain that the signature and message originated with A and A may not later deny having sent the message as it would be vir-tually impossible for the signature to be forged since it is a complex function of the message content itself.  A may also be assured that B cannot alter the message as the signature would no longer be valid.            According to other aspects of the invention the interrupting of communications between A and B by an eavesdropper and the subsequent sending of stale messages is prevented.  As a still further feature of the invention, an eavesdropper is prevented from sending the "forged" approval from the CPU to the receiver B.
