The outlet of the approach channel is surrounded by a sharp edge, and the jetting orifice is configured for directing the jet against the sharp edge. | 08-04-2011 |
20110248099 | AEROSOL SPRAY DEVICE - An aerosol spray device comprising a pressurised or pressurisable container and a spray discharge assembly mounted on the container. The spray discharge assembly comprises a valve stem moveable from a first limit position to a second limit position to effect spray discharge from the device, a spray outlet region having an outlet orifice from which fluid from the container is discharged, and a flow conduit for supplying fluid from the container to the spray outlet region. The flow conduit has at least one first inlet for liquid from the container and at least one second inlet at the same distance along the conduit as the first inlet(s) or downstream of the first inlet(s) for propellant gas from a headspace of the container. A valving arrangement is adapted such that movement of the valve stem from its first to second limit position opens the first and the second inlets to cause a bubble laden flow to be created in the flow conduit and movement of the valve stem back to its first limit position closes the first and the second inlets. | 10-13-2011 |

20090237299 | Method of Creating an Image File and a Digital Camera for the Same - A method of creating an image file and a digital camera for the same. The method comprised the steps of: (i) generating and storing image data corresponding to a photo or video clip; (ii) sampling received GPS signals and storing the resultant GPS signal samples (hereafter “raw GPS data”); and (iii) creating a single file containing both the image data and the raw GPS data | 09-24-2009 |
20090284413 | MOBILE DEVICE COMPRISING A GPS RECEIVER - A mobile device comprising a GPS receiver for receiving GPS signals; a communications receiver for receiving historical ephemeris data from an external server; and a processor configured to determine later ephemeris data from the historical ephemeris data and to determine a GPS position fix from the later ephemeris data. In particular, the later ephemeris data may be valid for a time period greater than any single set of the historical ephemeris data. | 11-19-2009 |
20100002097 | METHOD OF POSITION STAMPING A PHOTO OR VIDEO CLIP TAKEN WITH A DIGITAL CAMERA - A method of appending a position stamp to an image file of a photo or video clip taken with a digital camera having a GPS antenna and a GPS RF front-end including an analogue to digital converter for receiving GPS signals and outputting GPS signal samples together with a digital camera and computer for the same. | 01-07-2010 |
20100054310 | METHOD OF ACQUIRING A RECEIVED SPREAD SPECTRUM SIGNAL - A method of acquiring a received spread spectrum signal comprises receiving a spread spectrum signal, analysing the received signal to detect interference within the received signal, and adapting the baseband processing of the received signal to reduce power consumption during periods of detected interference. This allows the GPS processing resources to be focussed on areas of signal where there is little or no interference, and this is possible without modification to the source of interference. The interference is detected from an analysis of the received signal, and in particular before the baseband digital signal processing. | 03-04-2010 |
20100070129 | VEHICLE DATA RECORDER - A vehicle data recorder comprises a front end RF receiver and a memory device for storing sampled satellite positioning signal data from the 5 front end receiver. The memory device stores a block of sampled data corresponding to a time period leading up to the time of an incident involving the vehicle. The data can be stored with a low cost system, and can be analysed after the incident by a remote data processing station. | 03-18-2010 |
