Title: Improving signal to noise ratio in holographic displays
Inventor: BUCKLEY EDWARD
IPC: H04N5/21
Filed: 2006-06-29
Abstract: This invention relates to method, apparatus and computer program code for improved techniques for holographic image display systems, and particularly to a method of generating data for a pixellated hologram display device provided with a phase mask 25 for generating a holographic image 14 in a replay field. The method comprises inputting image data 102 for said holographic image and performing a holographic transform on data in a digital signal processor 100 to generate hologram data 104. Hologram data is supplied to a spatial light modulator which modulates light from a laser light source 12. Phase mask 25 is used to adjust said hologram data for corresponding regions of said hologram display. Hologram data is quantised to generate quantised pixel data for display on said hologram display, wherein said quantising is performed successively for pixels of said hologram display device. The method further comprises determining an error in hologram pixel data resulting from quantisation and using the errors to compensate the hologram data prior to further quantisation of hologram data in order generate further quantised pixel data. Thereby, the displayed holographic image is subject to less noise due to the quantisation process, resulting in an improved signal-to-noise ratio (SNR). Also disclosed are methods for displaying holographic image data wherein the SNR is controlled such that the SNR is different in different regions of the displayed image, and for configuring the calculation of hologram data to suppress conjugate images in the replay field.

Title: A safety system for a vehicle
Inventor: KARLSSON JOHAN
IPC: B60R21/013
Filed: 2006-07-27
Abstract: An object detection arrangement detects and classifies objects 5, 6 in the vicinity of a vehicle 1 and determines the locations thereof. An eye detection arrangement determines the positions of the eyes of a driver of the vehicle 1. From these detections, a processor determines whether an object is at least partly hidden from the driver by a part of the vehicle, e.g. in areas 7-11, and an output arrangement provides an output signal if an object, classified as hazardous by the object detection arrangement, is determined to be so hidden. The eye detection arrangement ensures that the blind spot areas are better defined, even though the driver may shift position. This reduces the number of false alarms, when the object can actually be seen by the driver, thus reducing the likelihood of warnings being ignored.

Title: Floating foam for fire fighting
Inventor: ELLIOTT MARK
IPC: A62D1/00
Filed: 2006-09-28
Abstract: Foams and methods of using foams for fighting fires in confined areas (i.e., mine shafts) are provided. The foam includes a surfactant; a non-flammable liquid; and an inert gas having a density substantially less than air. Particularly the density of the foam is substantially less than the density of air and the gas is either helium or a helium/nitrogen mix. The light foam will allow a basic form of directional control of the foam because the light foam will float towards the ceiling of a cavern or mine shaft. This offers fire fighters several options in extinguishing an underground fire.

Title: Microseismic event monitoring system
Inventor: EISNER LEO
IPC: G01S5/08
Filed: 2007-07-03
Abstract: A method for monitoring hydraulic fracturing processes and other microseismic events determines the position and azimuth of a seismic receiver 131. The receiver 131 is used to determine the directions of at least two seismic events 15 at different known locations. From this an estimate of the receiver 131 position is derived. The back azimuth of the seismic events 15 is preferably determined using the particle polarisation of seismic waves from spatially distributed seismic events.

Title: Inserting graphical features into video images
Inventor: WILLIAMS MICHAEL JOHN
IPC: G06T15/20
Filed: 2007-09-07
Abstract: An image processing method introduces a graphical feature or effect into a part of one or more video images of a scene. The scene includes a view of a plurality of objects (eg players) disposed on an object plane (eg sports field 1), the part of the video images including one of the plurality of objects on the object plane.

Title: Resuming control of resources by a processor on exiting a sleep mode and disabling an associated monitor.
Inventor: HAMMARLUND PER
IPC: G06F9/46
Filed: 2004-06-16
Abstract: A method of handling locks in a system comprises the steps of creating a queue element (a node) and associating it with a processor waiting for a contended lock. A monitor is then set up to monitor the node and the processor relinquishes its resources and is put into a sleep state. The node is monitored and when an event occurs the processor is exited from the sleep state and resumes control of the previously relinquished resources. Once awake the monitoring of the node is disabled. Relinquished resources may be combined to form larger resources for non-sleeping processors. Relinquishing resources comprises the steps of relinquishing registers and entries in instructions queues, buffers and reorder buffers. An event may comprise a processor reaching its turn in to claim ownership of a lock or the lock becoming available. Initiating the monitor comprises setting up a monitor address associated with the queue element or node.

Inventor: SEED LEONARD PAUL
IPC: C02F1/20
Filed: 2008-05-12
Abstract: A system is disclosed for extracting ammonia from a wastewater stream, and for transferring the ammonia into a secondary water circuit, wherein the dissolved ammonium is electrolysed and transformed into gaseous nitrogen. The system makes use of a membrane of gas-permeable hydrophobic material. The system includes a wastewater circuit and a secondary water circuit, a membrane chamber 25 in which a membrane physically divides the chamber into a wastewater sub-chamber and a secondary water sub-chamber, the membrane prevents the passage of water between the two sub-chambers but is permeable to ammonia gas.

The ammonia gas is transferred into the water in the secondary water circuit, this is then transformed in an electrochemical reactor 49 into nitrogen gas. The system includes a gas disposal unit. Also claimed is a procedure for removing ammonia from a body of secondary water, in which pH sensors are used to control operation.

Title: Phased array antenna with a rhomboid shaped aperture and rhomboid shaped modules.
Inventor: RABY SCOTT A
IPC: H01Q3/26
Filed: 2008-09-15
Abstract: A phased array antenna 100, or a method of making such an antenna, comprises a first rhomboid shaped printed circuit board on which an array of antenna elements in a uniform pattern with an overall rhomboid shape is formed and where a first electrical connector is arranged on a peripheral edge of the printed circuit board. The phased array antenna 100 may have a bus bar adjacent to peripheral edges of the array. The array antenna 100 may be expandable by the addition of rhomboid shaped sub-array modules. The rhomboid shaped sub-arrays enable a modular aperture to be formed without producing any gaps between columns or rows of adjacently positioned sub-arrays. Thus, a uniform, consistent spacing is maintained between all the antenna elements on the array. This improves antenna radiation and low observability performance for the antenna system, as well as reducing the overall size of the antenna aperture and its cost of construction.

Title: Frequency generation using a delay locked loop
Inventor: LESSO JOHN PAUL
IPC: H03L7/081
Filed: 2008-12-29
Abstract: A frequency generation circuit comprises an input for receiving a signal at a first frequency F1, a divider 14 for producing a second, intermediate frequency F2, and a delay locked loop circuit 16 which receives the intermediate signal and generates an output signal by multiplying the intermediate signal by a multiplication ratio. The division ratio of the divider and the multiplication ratio of the delay locked loop are co-prime. The delay locked loop circuit 16 includes a voltage controlled delay line 22, which may employ an edge combiner (40, fig. 2) or a phase interpolator (60, fig.3) to produce the output signal from the cells of the delay line. The delay line introduces a delay that is made to be equal to one period of the clock signal at the intermediate frequency F2. The arrangement provides a frequency multiplication circuit based around a delay locked loop, but which allows non-integer multiplication ratios to be achieved.
