Title: Igniting a neutralising plasma in ion irradiation apparatus
Inventor: HAMAMOTO NARIAKI
IPC: H05H1/24
Filed: 2002-04-25
Abstract: Secondary electrons 40 are produced by the collision of ion beam 2 with a plasma generating gas 18 flowing from a plasma generating chamber 10 into in a vacuum chamber 8. A positive voltage applied to the plasma chamber 10 by a DC power source 36 draws the secondary electrons 40 into the plasma chamber 10 where they are used, in combination with a radio frequency wave introduced by an antenna 20, to trigger the ignition of a plasma 16. The plasma 16 is emitted through aperture 14 into the vacuum chamber 8, upstream of a semiconductor substrate 4 being processed. Electrons in the plasma suppress the charge-up of the substrate 4. The DC power source 36 may be of the bipolar type, being switched by controller 38 once the plasma has been ignited, to applying a negative voltage to the plasma chamber 10 in order to promote emission of the plasma 16 through emission aperture 14.

Title: Rearranging codeword sequences for prioritising the mapping of bits
Inventor: KIM MIN-GOO
IPC: H04L1/00
Filed: 2002-06-10
Abstract: A stream of bits from an encoder or interleaver is divided into a first period comprising bits with higher priority (e.g. systematic bits) and a second period comprising bits with lower priority (e.g. parity bits). The bits of the first period are mapped to bit positions within 2<SP>m</SP>-ary modulation symbols having an associated higher reliability, whereas the bits of the second period are mapped to the remaining positions of lower reliability. For example, in an 8 PSK modulation scheme, higher priority bits are mapped to second and third bit positions of three-bit modulation symbols, and lower priority bits are mapped to first bit positions (figure 9). Arrangements for 16 QAM and 64 QAM modulation schemes are also disclosed (figures 11 and 13), with the bit stream being divided into three periods or classes of protection for 64 QAM. A higher power level may be allocated to either the front or rear part of the mapped stream of bits.

Title: A safety device for multiple wheel nuts
Inventor: MARCZYNSKI MICHAEL
IPC: B60B7/20
Filed: 2003-12-17
Abstract: A safety device (10) comprises a plurality of wheel nut position indicators (30) captively but rotatably mounted in a holder (12). The position indicators are attachable to respective wheel nuts (40) by means of fastener covers (50). When attached, the fastener covers (50) act to secure the device to a wheel and to transfer any rotational movement, i.e. loosening, of a wheel nut (40) to an associated position indicator (30). The indicators (30) each have an indicator portion, e.g. a triangular pointer (34) and are so arranged that this portion emerges from the holder and hence becomes visible when any such rotation occurs. By removing a fastener cover (50) an indicator (30) is disengaged from a wheel nut (40) and the individual wheel nut can be tightened without having to remove the entire device (10). The invention helps reduce errors in wheel nut maintenance and inspection and allows simultaneous application of a plurality of indicators in one operation.

Title: Registering a water marked image with an original image by calculating distortion vector estimates
Inventor: TAPSON DANIEL WARRAN
IPC: G06T7/00
Filed: 2004-12-09
Abstract: A data processing apparatus detects a code word, which has been embedded in a water marked image. The apparatus recovers a code word estimate from the water marked image and correlates the estimated code word with each code word from a set of possible code words. The apparatus detects whether a code word is present from a result of the correlation. In order to improve a likelihood of correctly detecting a code word, which may be present in a water marked image, the data processing apparatus includes a registration processor 104. The registration processor includes an image analyser 200 operable to divide the water marked image into a plurality of image blocks, a vector estimator 202 a forward probability estimator 204 and a backward probability estimator 206. The vector estimator generates for each of the image blocks a probability distribution of distortion vectors representing an observed shift of the image block with respect to a position of the block in the original version of the image. The forward probability estimator generates for each of the image blocks a forward probability distribution of possible distortion vectors within the image block from the observed probability distribution of distortion vectors and the distortion probabilities from previous image blocks following a predetermined path through the blocks. The backward probability estimator generates for each of the image blocks a backward probability distribution of possible distortion vectors within the image block from the observed distortion probabilities for the image block and from subsequent image blocks following the predetermined pattern. A combining engine 212 determines a most likely distortion vector for each image block from a combination of the estimated distortion vector, the forward probability estimate and the backward probability estimate for each image block. An inverse distortion engine 219 applies a reverse of the most likely distortion vector for each image block to register the water marked image with the original image to improve a likelihood of correctly detecting the water mark code word.

Filed: 2005-06-16
Abstract: A movable member, such as a rod 208, is used to actuate a flow control device 200, such as a sleeve valve 202 and 204, the movement of this member, when it actuates the flow control device, also causes a detectable change, such as a pressure spike, within a chamber 216 which is detected by a sensor, the sensor output is used to confirm actuation of the flow control device 200. The sensor is not directly monitoring the flow control device or the actuation system but is detecting a resultant change within a chamber caused by movement of the movable member.

Title: Tractor with valve system
Inventor: BLOOM DUANE
IPC: E21B4/18
Filed: 2001-12-03
Abstract: A hydraulically powered tractor includes an elongated body, two gripper assemblies, at least one pair of aft and forward propulsion cylinders and pistons, and a valve system. The valve system comprises an inlet control valve, a two-position propulsion control valve, a two-position gripper control valve, two cycle valves, and two pressure reduction valves. The inlet control valve spool includes a hydraulically controlled deactivation cam that locks the valve in a closed position, rendering the tractor non-operational. The propulsion control valve is piloted on both ends by fluid pressure in the gripper assemblies. The propulsion control valve controls the distribution of operating fluid to and from the propulsion cylinders, such that one cylinder performs a power stroke while the other cylinder performs a reset stroke. Each end of the gripper control valve is piloted by a source of high-pressure fluid selectively admitted by one of the cycle valves. The gripper control valve controls the distribution of operating fluid to and from the gripper assemblies. The cycle valves are spring-biased and piloted by fluid pressure in the propulsion cylinders, so that the gripper control valve shifts only after the cylinders complete their strokes. The pressure reduction valves limit the pressure within the gripper assemblies. These valves are spring-biased and piloted by the pressure of fluid flowing into the gripper assemblies. Some or all of the valves include centering grooves on the landings of the spools, which reduce leakage and produce more efficient operation. The propulsion control and gripper control valves include spring-assisted detents to prevent inadvertent shifting. The speed of movement of the tractor is controlled by the pressure of the operating fluid, the flow rate of the operating fluid and the tension exerted on the tractor by a drill string.
