Title: Re-programming a memory device whilst preserving a real time clock
Inventor: SCHMIDT JURGEN
IPC: G06F9/24
Filed: 1996-07-27
Abstract: The method includes the steps of installing a software real time clock (RTC) service routine running outside the flash memory device, wherein a counter measures the total re-programming procedure duration (100). The software RTC service routine running inside the flash device is stopped (102) and the current absolute unit time saved in a read/write accessible memory cell (104). A re-programming cycle is executed (106) and the updated application will be prepared to run (108). The unit time is set to the previous stored value (110) and the software RTC service routine running inside the flash device re-started (112). The software RTC service routine running outside the flash device is stopped (114) and the measured total re-programming duration added to the current RTC value (116). The application then recommences (118).

Patent GB-2304506-A (GB)
Title: Media access protocol
Inventor: KOOPMAN PHILIP J
IPC: H04J3/06
Filed: 1993-12-10
Abstract: If a transceiver has a message to send during an idle medium condition, it transmits a jam pattern onto the medium for a predetermined time (based on maximum network propagation delay). If a transceiver detects a jamming pattern, it inhibits its own transmissions and waits for the next slot progression. If multiple transceivers begin jamming within a propagation delay of each other (within the network vulnerable time), their jamming transmissions will not destructively interfere with each other. When jamming ceases, all transceivers begin a slot progression. Thus, the end of the jamming period when all transceivers have finished jamming serves as a network-wide synchronization for the start of an implicit token slot progression.

Title: Method and apparatus for removing ethylbenzene from mixed xylenes stream
Inventor: WINTER GEORGE R
IPC: C07C7/00
Filed: 1996-05-08
Abstract: A method and apparatus for optimizing the production of p-xylene from a feed stream of a mixture of xylene isomers and ethylbenzene is described. The feed stream (121) is first fed through a pretreatment reactor (120) which converts the ethylbenzene into benzene and light hydrocarbons which are removed from the feed stream. The resulting mixture of xylenes is fed into a isomerization unit (114) which enriches the p-xylene concentration in the mixture at the expense of the ortho and meta isomers. The resulting effluent (116) is fed into a separator (112), which separates out the p-xylene (113). The remainder is combined with additional mixed xylenes which are then fed back into the isomerization unit (114), thus providing a continuous process for removing ethylbenzene from the initial feed stream of ethylbenzene and mixed xylenes, and converting the mixed xylenes into p-xylene.

Title: Nuclear Magnetic Resonance well logging
Inventor: ISKOVICH GREGORY B
IPC: G01V3/32
Filed: 1997-09-11
Abstract: A method of determining the number of exponential decay modes in spin echo amplitude signals produced by a nuclear magnetic resonance well logging instrument includes dividing the time interval between initiation and termination of measurement of the spin echo amplitude signals into 2 r - 1 equal length segments, where r is a positive integer. Integrals of the spin echo amplitude signals with respect to time in each of the segments are calculated. Best fit functions are calculated for the spin echo amplitude signals, and integrals with respect to time of apparent amplitudes of the best fit functions at each time corresponding to a time at which the spin echo amplitude signals were generated. The integrals of the spin echo amplitude signals and the integrals of the apparent amplitudes from each segment are arranged into symmetric matrices each having dimensions r r . A norm and a standard deviation of the matrix of the spin echo amplitude integrals is calculated. If the norm of the determinant of the matrix of the integrals of the spin echo amplitude signals is less than or equal to a selected confidence factor multiplied by the standard deviation of the determinant of the matrix of the integrals of the spin echo amplitude signals, then the number of exponential decay modes in the spin echo amplitude is equal to r - 1. If the inequality * bullet *G1 is not satisfied, r is increased by one and the process is repeated.

Title: Cancelling fixed pattern noises in solid state camera output video signal
Inventor: YONEMOTO KAZUYA
IPC: H04N5/374
Filed: 1997-10-01
Abstract: Cancellation of vertical string-like fixed pattern noises in the output video signal from a solid state imaging device comprising a two-dimensional array of pixel sensing elements caused by threshold voltage dispersions in the device circuits is effected by resetting the sensing elements after power has been supplied to the device and immediately before the pixel output signals are read from the device, i.e. in a condition when there is no signal originating from incident light. The resulting output reference signal is stored and subsequently combined with the output video signal from the device which is obtained from the sensing elements before they are reset, i.e. in response to an optical input. In a further arrangement each vertical output line 213 of the imaging device array 211 is connected via a sampling switch 215 to two storage capacitors 216,217 which are respectively connected to a reference potential line 218 via further switches 219,220 and to an output line 222 via a horizontal selection switch 221. In operation the switches are controlled so that the reference dark-state reference signal is stored in one capacitor and the bright-state video output signal in the other capacitor from which they are sequentially read and output on line 222 for subsequent combination.
Patent GB-973422-A (GB)
IPC: B41F13/02
Abstract: 973,422. Feeding webs. PORTALS Ltd., and A. J. TOOTH. Aug. 8, 1962 [Aug. 16, 1961], No. 29640/61. Heading B6B. [Also in Division G3] Relates to a longitudinal registering of a web being fed into a processing machine, wherein means are provided for measuring at a sensing station along the web and in relation to the timing of a particular operation in the process, the distance from the sensing station of a mark on the web. In the particular embodiment shown, a web 2 is fed by continuously driven nip rollers 3 to be cut into sheets by a rotary knife 5. The registration apparatus comprises photo-electric means, 13, spaced along the web from the knife at the required nominal sheet length, which produces an electric signal when sensing a mark such as one of a plurality of water marks 6, 7 and 8, spaced along the web also at the required nominal length. The rotary knife 5 is driven through epicyclic gearing 14, a clutch 11, and a variable gear-box 9 by a motor 10, which also drives the nip rollers 3. A rotary switch 12 is provided to give a reference signal once per revolution of the knife 5. A correction motor 15 is connected to drive the planet gear carrier of the epicyclic gear 14 to advance or retard the speed of the knife 5 relative to the nip rollers 3. The epicyclic gear could equally be applied to the nip rollers and give the same result. A correction pulse generator 17, is driven directly by the correction motor 15, and is capable of producing 10,000 or more discrete pulses for one revolution of the knife 5 when the motor 15 is driven at maximum speed (the main motor 10 being stationary). Each pulse therefore represents a small fixed percentage of the nominal sheet length. The generator 17 may be of the type having a rotating transparent disc engraved with opaque radial lines which are sensed by a photo-electric device. An error pulse generator 18, driven by the gear-box 9, produces discrete pulses, each pulse corresponding to the same percentage of the nominal sheet length represented by a correction pulse. Two pulse counters 19, 20, are permanently connected to receive pulses from the error and correction pulse generators respectively. When the machine is operating, a signal from either the switch 12 or the photo-electric device 13, whichever is first, energizes the error counter 19 so that the error pulses are counted. A signal generated from the device 13 or the switch 12, whichever is last, de-energizes the error counter 19 so that it stops counting. At the instant the error counter is de-energized, the correction motor 15 is started, and correction pulses generated are counted by the correction counter 20. A coincidence sensing device 27 connected between the error and correction counters continuously compares the counts stored until coincidence occurs. The device 27 then stops the correction motor 15, since, longitudinal registration is achieved, and resets both counters in preparation for the next sheet. An automatic brake acting on the correction motor 15 may be applied 5 pulses before coincidence occurs, which will prevent over-run.

Title: Alarm system with anti-tamper devices
Inventor: RUST ANDREW
IPC: G08B29/10
Filed: 1998-06-26
Abstract: An alarm system (10) comprises at least one sensor (11) which is connected to a central control panel (12). The sensor (11) acts to detect the presence of an intruder and sends an alarm signal to the control panel (12). The control panel (12) in turn upon receipt of the alarm signal sends a signal to an alarm indicator (13) which can include both a visual alarm in the form of a flashing or stroboscopic light and/or an audible alarm in the form of a piezo electric buzzer. Each of the sensor (11), control panel (12) and alarm indicator (13) have an anti-tamper device associated with them which causes the production of an alarm signal if an intruder attempts to gain access to the internal parts of these devices to disable or interfere with operation of the alarm system. In the improved system of the invention, it is possible for an engineer to enter a code into the control panel (12). In response, a predetermined number of signals over a predetermined period of time are sent to the alarm indicator (13) to deactivate the anti-tamper device. This means that a bone fide engineer can deactivate the anti-tamper devices so that routine service and maintenance work can be carried out safely.
