Title: Transmission of signalling information in an ofdm communication system
Inventor: DE COURVILLE MARC G BERNARD
IPC: H04L27/26
Filed: 2006-05-01
Abstract: An Orthogonal Frequency Division Multiplexing, OFDM, transmitter comprises a signalling data generator (113) which generates a set of data symbols indicative of physical layer characteristics of data transmissions from the OFDM transmitter (100). A first symbol generator (115) and second symbol generator (117) generates a first and second OFDM signalling symbol by allocating the set of data symbols to subcarriers. The allocation of the physical layer data symbols to subcarriers is different for the first OFDM signalling symbol and the second OFDM signalling symbol. A data packet generator (105) and transmitter (101) generate a data packet and transmit this to an OFDM receiver (300). The OFDM receiver (300) determines the physical layer data symbols by combining the data symbols of corresponding subcarriers of the first and second OFDM signalling symbols and uses the resulting information to decode the user data of the data packet.

Title: Securing device for head tube bearings, and method for securing head tube bearings
Inventor: WEIDNER FRANK
IPC: B62K21/06
Filed: 2006-05-12
Abstract: The invention relates to a securing device for head tube bearings of two-wheel vehicles, e.g. bicycles. The head tube bearing comprises a top and a bottom bearing unit, with the aid of which a tubular shaft of the fork of the two-wheel vehicle can be rotatably connected to a head tube of the frame of the two-wheel vehicle. The inventive securing device is composed of a thrust bearing which can be locked onto the tubular shaft (2) above the top bearing unit (3) and is effectively connected to a mechanism applying an axial pressure to the top bearing unit (3), henceforth referred to as an axial pressure mechanism. This has the advantage that securing the clearance of the head tube bearing is entirely independent of the handlebar fixture. The thrust bearing is locked in relation to the tubular shaft once the disclosed thrust bearing comprising the axial pressure mechanism has been placed on the tubular shaft and has been slid onto the top bearing unit until reaching the stop. The axial pressure is then applied to the top bearing unit by means of said mechanism.
