Title: Critical line first paging system
Inventor: ENGLISH ROBERT
IPC: G06F12/08
Filed: 1992-08-27
Abstract: A memory management system for minimizing I/O data transfer latency during the resolution of page faults. When a page fault is received by the microprocessor, the desired page is read into the microprocessor's local memory, and a mask bit corresponding to the critical line which caused the page fault is cleared. The process which requested the critical data line proceeds as soon as the mask bit for the critical data line is set, thereby preventing the microprocessor from having to wait for the entire page to be transferred into local memory. In addition, the address of the critical data line is provided to the external memory so that the data lines in the page may be sent out of order. In particular, the critical data line may be sent first so that it is the first data line stored in the local memory during memory I/O. <IMAGE>

Title: Sport shoes
Inventor: MADJDNIA ALIREZA
IPC: A43B3/00
Filed: 1993-10-08
Abstract: A Sports shoe which incorporates a sensory device to measure the stepping timing information in order to transmit the data to an external (or alternatively internal device) where it is manipulated to compute and monitor factors such as No. of steps per time period, acceleration, speed, travel led distance or measure of fitness. The analogue signal produced by the piezo electric sensor is amplified before it is sampled by the A/D device. The serial digital data is assigned with a reserved identification code. The data is then modulated on an R.F. carrier. The sensor/transmitter section is powered using a rechargeable battery. The R.F. signal transmitted from the shoe and picked up by the receiver antenna eg on a watch like unit on the wrist is amplified and then demodulated. The microcontroller manipulates the incoming stepping data to compute the desired factors. An optical sensor detects the users heart beat to be used in computation of fitness factor.

Title: 5B/6T data encoding
Inventor: CUNNINGHAM DAVID GEORGE
IPC: H03M5/18
Filed: 1994-07-07
Abstract: A method of encoding data words containing five binary digits into code words of six ternary digits involves use of a specific 5B/6T code table, the encodings in which are selected to provide d.c. balance, inherent error detection capabilities and, for an effective data rate of 100 Mbit/s, a low power spectral density for frequencies above 30 MHz.

Title: Identification tag with environmental sensing facility
Inventor: HOWELL SIMON KENT
IPC: G06K7/00
Filed: 1996-01-04
Abstract: A radio frequency identification tag 1 which is energised by a radio signal from a reader station 11 to transmit a code identifying the tag. The tag incorporates a sensor 7 responsive to an environmental parameter 8 to which the tag is exposed, and when the tag is energised by an adjacent reader the radio signal returned to the reader includes a code representing a measurement value corresponding to an output of the sensor. Thus the tag not only identifies the item to which it is attached, but also provides a measurement of the parameter to which the sensor is responsive. The measurement may be the instantaneous output of the sensor or a stored output, for example the maximum or minimum temperature to which the sensor has been exposed.

Title: Detection of spread spectrum signals
Inventor: HOUGHTON ANDREW WARREN
IPC: G01S3/04
Filed: 1995-09-20
Abstract: A spread spectrum signal detection system comprising two spatially separated receivers, a correlator, such as a time integrating correlator employing acoustic-optic cells, which is connected to the outputs from the two receivers to produce a signal representative of the cross correlation function of the two spread spectrum signals, a filter arranged to transmit only the central portion of the cross correlation function and a signal processor to produce the cross spectral density and thereby determine the presence of the spread spectrum signal. The direction of arrival of the spread spectrum signal can be determined by measurement of the angle of the phase slope of the cross spectral density. The acoustic-optic cells can be Bragg cells. The output signal from one of the receivers can be applied to a first Bragg cell arranged to point modulate light from a laser light source, the output then being transmitted through a beam expander to a second Bragg cell to which the output signal from the second receiver can be applied, the output from the second Bragg cell then being detected by a photo-detector array. The output from the second Bragg cell can be spatially filtered by providing adjustable imaging optics arranged such that only light corresponding to the central portion of the cross correlation function is transmitted. The processor can be arranged to demodulate the signals to produce data corresponding to the central portion of the cross correlation function and to Fourier transform the data to produce the cross spectral density.

IPC: A61M16/18
Filed: 1997-03-24
Abstract: The anaesthetic evaporator has a gas inlet 5, a gas and vapour outlet 9, control valves 11 and 14 between the inlet and outlet and an evaporation chamber 3 and a ventilation valve 18 to vent the chamber 3 to the atmosphere. A control member 4 controls a metering unit 2 and has a transport position 19 in which it closes all three valves, an off position 20 in which the ventilation valve 18 is open but the control valves are closed and a variable concentration setting 21 in which the ventilation valve is closed and the control valves are open. To switch the evaporator on after transportation, the control member is moved from the transport position, through the off position to the concentration setting required, and hence in the progress vents the chamber to the atmosphere.
