Patent number: 8040967Abstract: A signal is received in a telecommunication network in the form of P signals received on P corresponding antennas, where P is greater than or equal to 1. The received signals correspond to a multi-carrier signal transmitted in the form of flames comprising symbols occupying corresponding positions distributed along a time axis and along a frequency axis; a frame comprising M blocks each having at least N reference symbols. The reference symbols in each of the blocks satisfy a first maximum spacing between each other along the time axis and a second maximum spacing between each other along the frequency axis, less than a first value and a second value respectively, M being an integer number equal to at least two. M estimated noise power values are determined at frame level, each related to one of the M emitted reference symbol blocks. Values of the estimated noise power for the other symbols in the frame are then obtained from the determined estimated noise power values.Type: GrantFiled: October 5, 2006Date of Patent: October 18, 2011Assignee: EADS Secure NetworksInventors: Philippe Mege, Christophe Brutel

Patent number: 8011447Abstract: A method of surveying drill holes, typically for use in underground mining situations where the holes are bored using a top hammer drill rig (10), utilizes a survey tool located adjacent the drill bit (1) which is used to log position readings as the drill string is withdrawn from the hole after the drilling operation. In this manner, it is possible to log the actual hole bored by the drill string (3) in real time as the drilling operation proceeds, and show deviation from intended hole positions (5) or (6). The survey tool typically includes an inertial survey package, a power source, and a data logger with the survey package selected from the group comprising commercially known inertial known survey packages, for superior characteristics of resistance to vibration and impact. The survey tool is maintained in a sleeping mode while drilling is undertaken, and activated to provide position data as the drill string is progressively withdrawn from the actual hole path (3).Type: GrantFiled: January 24, 2005Date of Patent: September 6, 2011Assignee: CMTE Development LimitedInventors: Scott David Keniston, Paul J.

Patent number: 7988145Abstract: A hold-down device is disclosed for holding down the leading edges of sheet materials, such as multiple-ply sheets or integrated forms, disposed in a tray of a printer in a horizontal or flat position prior to feeding the leading edge of the top sheet or integrated form into the printer feed mechanism. Because some sheet materials are prone to curling, which causes jamming in the feed mechanism or downstream in printing path within commonly used printers, the disclosed hold-down device maintains the leading edge of the top sheet in a flat or horizontal position so it can be reliably and evenly received in the feeder mechanism of the printer, thereby reducing the chances of jamming when sheet materials that are prone to curling, such as multiple-ply sheets or integrated forms, are being printed. The hold-down device includes a base with two ends. Each end may include a retainer or other means for detachably connecting the base to the paper tray of the printer.Type: GrantFiled: May 19, 2009Date of Patent: August 2, 2011Assignee: Chicago, Tag & LabelInventors: F.

Patent number: 7987605Abstract: A combination target reflector, light emitter and bracket assembly is disclosed for use in marking points during the taking of a land survey. The combination is pivotally connected to a central rod of a target tripod or a tripod that supports a target reflector. The disclosed combination includes first and second arms and a light emitter that is held in axial alignment with the target reflector. The first arm is pivotally and perpendicularly connected to the central rod of the tripod. The second arm is perpendicularly connected to the target reflector and the light emitter. The tripod can be moved close to a point to be marked, the tripod can be adjusted to plumb the target reflector and then the second arms, light emitter and target reflector can be moved out of axial alignment with the rod to mark the point without moving the tripod. As a result, the conventional trial and error procedure currently employed can be avoided.Type: GrantFiled: February 23, 2010Date of Patent: August 2, 2011Inventors: Roger Fleenor, Richard John Fleenor
