Title: Interference reduction between ofdm carriers by carrier spacing optimization
Inventor: BREHLER MATTHIAS
IPC: H04L27/26
Filed: 2009-06-09
Abstract: Systems and methodologies are described that facilitate sig-nal separation across different carriers within a wireless communications environment. The systems and methods can identify a carrier spacing that can be based upon a tone spacing associated with two or more carriers.  Such carrier spacing can be employed within a network in order to mitigate signal separation with multiple carriers. The subject innovation can further evaluate a carrier raster associated with a network in order to identify a car-rier spacing to ensure orthogonality between tones from different carriers.

Inventor: PAULSON PETER O
IPC: G01N29/04
Filed: 2009-08-05
Abstract: The invention locates impaired sections of a pipeline, such as sections where the wall of the pipeline has been weakened or thinned. It provides a moveable device which passes through the pipeline and which has a first station. The moveable device has means to locate its position accurately. There is a second station, which is mounted either on the moveable device or in association with a fixed location on the pipeline wall. Either the first station or the second station has an acoustic or seismic pulse generator, and the other has a pulse receiver. The time taken for a pulse to travel from the pulse generator to the receiver is found to vary with the condition of the pipeline wall at the location where the moveable device is located at the time it receives (or sends) the pulse. The rate of change of velocity of the pulse as the device passes different locations in the pipeline is also found to vary with the condition of the pipeline wall at such location.

Abstract: The invention relates to a method and system for determining an aerodynamic drag area CxA of a moving vehicle, for example a bicycle, in dependence upon the airflow yaw direction and speed without the use of a wind tunnel. The vehicle is equipped with sensors for collecting time- stamped values indicative of the vehicle speed, propulsion force, airflow speed and yaw angle of the airflow at various points during the trip. The trip data are then processed using successively refined hypotheses regarding the CxA(yaw) dependence to generate a plurality of elevation profiles for the travelled path. The generated elevation profiles are then evaluated based on available route elevation information to select a correct dependence of the aerodynamic drag area upon the yaw angle of the airflow.

Title: A method and apparatus for determining a mixing regime for use in the preparation of animal feed from a set of ingredients, and a system for producing the animal feed
Inventor: MCNAB KERR HUGH
IPC: A23N17/00
Filed: 2009-12-03
Abstract: A method and apparatus for determining a mixing regime for use in the preparation of an animal feed in which a main computer is programmed to store a master list of ingredients which are available to farmers and from which a farmer can select a specific set of ingredients for the preparation of animal feed. The main computer is programmed to store the ingredients in a look-up table cross-referenced with standard mixing periods to which the respective ingredients should be subjected during the mixing regime to produce an animal feed. Additionally, the look-up table contains mixing factors by which the standard mixing periods may be altered in order to take account of non-standard conditions, such as variations of the ingredients, the proportion of the particular ingredient, the average size or weight of the animals and the mixing apparatus and condition thereof in which the animal feed is to be mixed. The computer is programmed to determine the mixing period to which each ingredient is to be subjected in the mixing apparatus based on the corresponding standard mixing periods and any mixing factors which should be taken into account. The computer is programmed to then produce a sequence in which the ingredients are to be loaded into the mixing apparatus and the instants at which the respective ingredients are to be loaded into the mixing apparatus, so that each ingredient is subjected to the appropriate mixing period for that ingredient during the mixing cycle of the mixing regime, in order to avoid over-mixing and under-mixing of ingredients.
