Abstract: An echo processing technique for attenuating echo components of a direct signal X1n in a return signal Y2n. A receive gain Grn and a send gain Gen are calculated. The receive gain Grn is applied to the direct signal and an input signal X2n is produced and emitted into an echo generator system. The send gain Gen is applied to an output signal Y1n from the echo generator system and the return signal Y2n is produced. A coupling variable COR is calculated which is characteristic of the acoustic coupling between the direct signal X1n or the input signal X2n and the output signal Y1n. The receive gain Grn and the send gain Gen are calculated on the basis of the coupling variable.

Abstract: Method and arrangement for dispersing fuel 62 within a fuel containment system 60 of an aircraft 30 including utilizing a fuel containment system on an aircraft that is located at least partially within a wing 34 of the aircraft and defines a reservoir portion 42 and a remote portion 44. Fuel is pumped during at least aircraft flight operation from the reservoir portion to the remote portion at a pumped rate 80, while simultaneously fuel that is contained in the remote portion of the fuel containment system is permitted to drain to the reservoir portion at a drainage rate 82. The drainage rate is less than the pumped rate. A fuel mass 64 is accumulated in the remote portion of the fuel containment system because of a difference between the pumped rate and the drainage rate and as a result, a counteractive moment 49 is induced in the aircraft that is opposingly directed to a lift moment 46 caused by wing-lift 45 during aircraft flight.

A task interconnection logic block (16) is connected to each task unit for communicating actions from a source task unit to a destination task unit. Each task unit includes a processor (18) for processing the steps of the associated task when a received action requests such a processing. A status manager (20) handles actions coming from other task units and builds actions to be sent to other task units.

Abstract: Method and apparatus for efficient routing of mobile node packets. Nodes in a network are configured to classify a received flow from a mobile node to a second node based upon a home address option in a packet in the flow if the address is present. The address is a home address of the mobile node. The classification has associated reserved resources at each node for the received flow. Therefore, the Quality of Service is maintained for the flow between the mobile node and the second node if the mobile node moves to a new location. Resources reserved in nodes in the old path are torn down and released, while reserved resources in nodes in the old and the new path need not be reserved again.

Abstract: A device is described that may be positioned at a location in an intervertebral disc for diagnosis or treatment of the disc. Treatment may include, for example, applying energy or removing material, and may decrease intradiscal pressure. Radiofrequency energy may be applied. A percutaneous method of repairing a fissure in the annulus pulposus comprises placing an energy source adjacent to the fissure and providing sufficient energy to the fissure to raise the temperature to at least about 45-70° C. and for a sufficient time to cause the collagen to weld. An intervertebral fissure also can be treated by placing a catheter with a lumen adjacent to the fissure and injecting sealant into the fissure via the catheter, thereby sealing the fissure. An intervertebral fissure additionally can be treated by providing a catheter having a distal end, a proximal end, a longitudinal axis, and an intradiscal section at the catheter's distal end on which there is at least one functional element.

Abstract: An apparatus for bathtub heater control configured for two distinct functional operations; i.e., nominal control and safety oversight. The nominal control portion of the apparatus responds to normal operating parameters to heat the bathtub water to the desired temperature and to maintain it there within defined limits of precision. One aspect of this portion of the apparatus is proportionate temperature control. This feature employs heater power at less than full to achieve a fine degree of control at or near the desired temperature. Moreover, once the desired temperature is achieved, proportionate power of the heating element permits the maintenance of the water temperature at a more precise level. The safety oversight portion has the feature of operating only when power is applied to the heating element. This feature avoids unnecessary deactivation of the heater or heating element due to false sensing of an unsafe condition.
