Title: Magnetically suspended fluid pump and control system
Inventor: PREM EDWARD K
IPC: A61M60/822
Filed: 2000-02-09
Abstract: A blood pump for assisting a heart is provided by a stator and a rotor. The rotor is magnetically supported creating a suspension gap between the stator and the rotor. The rotor can be supported axially by a Lorentz force bearing and can be magnetically rotated. The stator can have a volute pump chamber and the rotor can have an impeller portion for pumping blood. The rotor can have a center bore as a primary blood flowpath. The suspension gap can be a first retrograde blood flowpath. An axial gap between the impeller and the volute housing can be a second retrograde blood flowpath.  The blood pump can also have an axial position controller. The axial position controller can cause the axial bearing to adjust the position of the rotor.  The axial position of the rotor. The axial position of the magnetic suspension components can be adjusted to compensate for changes in the magnetic fields of the magnetic suspension components. The blood pump can also have a flow rate controller. The flow rate controller can have a member for measuring a dimension of a heart ventricle to control the flow rate to avoid overly distending or contracting the ventricle. A  method for operating the flow rate controller to create a pulsatile flow rate is also provided. A flow sensor can be used to avoid excessively low or reverse blood flow through the pump when a pulsatile flow rate is provided.

Title: Aerated immersed membrane system
Inventor: GUNGERICH CHRISTIAN
IPC: B01D63/04
Filed: 2000-05-04
Abstract: An element of immersed, suction driven, filtering membranes has a plurality of hollow fibre membranes suspended between upper and lower headers. The lower header is movable between a first position in which the fibres are substantially elongated and second position in which the two headers are closer to each other by between 1 and 4% of the un-potted length of the membranes. The weight of the lower header is sufficient to keep the lower header in the first position in substantially quiescent water while allowing the lower header to rise to the second position in upwardly flowing water. Aerators are mounted generally below the elements and supply scouring bubbles to each element at a higher rate and then at a rate less than one half of the higher rate in repeated cycles. The cycles are preferably between 10 seconds and 60 seconds in duration. The lower header rises to the second position when bubbles are supplied at the higher rate and falls to the first position when bubbles are supplied at the lower rate.

Title: Method and apparatus for performing packet loss or frame erasure concealment
Inventor: KAPILOW DAVID A
IPC: G10L21/02
Filed: 2000-04-19
Abstract: The invention concerns a method and apparatus for performing packet loss or Frame Erasure Concealment (FEC) for a speech coder that does not have a built in or standard FEC process. A receiver with a decoder receives encoded frames of compressed speech information transmitted from an encoder. A lost frame detector at the receiver determines if an encoded frame has been lost or corrupted in transmission, or erased. If the encoded frame is not erased, the encoded frame is decoded by a decoder and a temporary memory is updated with the decoder's output. A predetermined delay period is applied and the audio frame is then output. If the lost frame detector determines that the encoded frame is erased, a FEC module applies a frame concealment process to the signal. The FEC processing produces natural sounding synthetic speech for the erased frames.

Title: Reconfiguring diversity legs during cn-rnc interface streamlining
Inventor: NOGUERA-RODRIGUEZ JUAN
IPC: H04L12/28
Filed: 1999-08-20
Abstract: In a mobile communications network that employs diversity combining/splitting, CN-RNC interface streamlining can be accomplished more efficiently by reconfiguring the network diversity legs, which are combined into a single data stream by the serving radio network controller, wherein the serving radio network controller is directly connected to the core network via the CN-RNC  interface. Reconfiguration of the network diversity legs is accomplished by releasing the transport level connections which support the network diversity legs prior to CN-RNC interface streamlining, and establishing new transport level connections to support the reconfigured, network diversity legs subsequent to CN-RNC interface streamlining. To establish new transport level connections, the serving radio network controller dispatches binding information to each of the destination nodes associated with the network diversity legs. The destination nodes then utilize the binding information to bind network resources to the transport level connections which support the reconfigured network diversity legs between the destination nodes and the serving radio network controller.
