Title: Sports brace
Inventor: GODWIN ANDREW
IPC: A61F5/37
Filed: 1999-01-22
Granted: 2005-02-01
Abstract: A shoulder brace consists of a figure "8" strap tensioned between a lower loop anchored around a thigh and a collar or sleeve worn on an opposite upper arm corresponding to an injured shoulder so as to extend the upper loop diagonally across the torso, thereby immobilizing the upper arm to prevent shoulder abduction and external rotation after, for example, shoulder dislocation. The upper and lower loops crossover adjacent the hip, with lower loop mugged under the crotch so as to allow relatively unrestricted movement of the thigh, for example, during exercise. The shoulder brace is thus well adapted for use as a sports brace.

Granted: 2003-04-15
Abstract: In order to improve carrier to interference ratios on the down link in mobile communications networks, it is proposed to transmit on the down link in a beam steered at the base station towards the mobile terminal.        In order to do that it is necessary to know in which direction the mobile terminal is located. There is disclosed a method of ascribing a direction to the location of a mobile terminal from an antenna array. A sequence of symbols from each antenna in the array, is stored. The sequence contains a known training sequence. The sequence is space processed iteratively so as to produce the effect of the array having a major lobe in its polar diagram at a plurality of different successive directions. A set of cross correlations metrics is derived by calculating a cross correlation metric for each direction between the combined signals and the known training sequence. The ratio is calculated of the cross correlation metric for each direction to the power of the combined signals for that direction to produce a set of direction metrics. A direction is ascribed to the mobile terminal using the direction metrics to determine which direction is most likely.

Abstract: A balloon catheter is provided with a core insertable from a connector into an inside of a shaft. When an operation for insertion/retraction of the core is carried out by pinching an operating part, the core slides along the shaft and the depth of the core in the shaft is thereby adjusted. When the core is inserted deeper in the shaft, the region of the shaft with a high rigidity increases with the core out to the shaft's distal end. On the other hand, when the core is retracted to the fore side, the rigidity of the shaft at its distal end side becomes lower and the flexibility of the balloon catheter becomes higher.

Abstract: A method is described for producing a fiberoptic waveguide with a basic segment (11) and a phase shift segment (12), the basic segment (11) and phase shift segment (12) having fiber cores (K) of the same form and the fiber cores being aligned at a defined angle (.alpha.) to one another. In the method, use is made of an optical fiber (1) having a fiber core (K) of the abovenamed form, which fiber is twisted at least approximately by the abovenamed defined angle (.alpha.) and held fixed in this torsional position. Subsequently, a stress-relief zone (13) is heated inside the twisted fiber (1) until the torsion is released inside the stress-relief zone (13) and the basic segment (11) is produced on one side of the stress-relief zone (13) and the phase shift segment (12) is produced on the other side. In this case, the fixing of the torsional position is maintained until after solidification of the stress-relief zone (13).

Granted: 2007-04-24
Abstract: A device to provide control of the trajectory of a lighter than air vehicle, such as a balloon, is provided. A lifting device, such as a wing on end, is suspended on a tether well below the balloon to take advantage of the natural variation in winds at different altitudes. The wing can generate a horizontal lift force that can be directed over a wide range of angles. This force is transmitted to the balloon by the tether. Due to this force, the balloon's path is altered depending on the relative sizes of the balloon and the wing. A relatively small amount of power is needed to control the system, possibly with a rudder. As the energy of the wind provides most of the force, the wind's energy does most of the work. The balloon is able to avoid hazards, to reach desired targets, to select convenient landing zones, and to provide other operational advantages. As a result, fewer flights must be terminated early due to an inability to control the trajectory, and it is easier to obtain permission to launch since a planned flight path can be achieved within a greater range of conditions.
