Title: Ofdm position location signaling utilizing mutually exclusive subsets of subcarriers
Inventor: KRASNER NORMAN F
IPC: H04L27/26
Filed: 2005-09-07
Abstract: Position location signaling system, apparatus, and method are disclosed. Position location beacons can each be configured to transmit a frequency interlaced subset of orthogonal frequencies spanning substantially an entire channel bandwidth. The orthogonal frequencies can be pseudorandomly or uniformly spaced, and each beacon can be allocated an equal number of orthogonal frequencies. Adjacent beacons are assigned mutually exclusive subsets of frequencies can be modulated with an element of a predetermined data sequence. A mobile device can receive one or more of the beacon signals and determine a position using a position location algorithm that determines position in part on an arrival time of the beacon signal. Where the mobile device can receive three or more beacon signals, the mobile device can perform position location by trilateration to the beacon positions based, for example, on a time difference of arrival.

Title: Method and device for quenching flat steel products
Inventor: KUHN FRIEDHELM
IPC: C21D1/667
Filed: 2005-09-16
Abstract: The device comprises a high-pressure slotted nozzle (5) out of which water is sprayed upon a continuous metal sheet (4) to be quenched. A spiral roll (3) is provided downstream from the high-pressure slotted nozzle (5) and assists the lateral flowing off of the water over the lateral edges of the metal sheet. A channel effect arises between the spiral roll (3) and the nozzle housing (6) of the high-pressure slotted nozzle (5) whereby leading to an excessive accumulation of water on the surface of the metal sheet. This excessive accumulation of water disrupts the uniform cooling of the metal sheet and, as a result, is thereby removed by suction by means of a suction device (6 12). This suction device comprises a first duct (7) that, at the lower end, is immersed in the excessive accumulation of water and, at the top, leads into a second duct (8) whose two broadening sections (9) are each connected to a suction pump whereby leading away the suctioned water to the side.
