摘要:
Various methods, systems, and computer program products are disclosed for determining a location estimate of user equipment in a mobile network. For example, a method may include receiving measurement data that includes a time of arrival indication of data communicated between the user equipment and base stations of the mobile network. The method may further include processing only the received measurement data that is within a particular time window and excluding some of the received measurement data outside the particular time window. The method may further include determining a sync value based on the received measurement data within the time window. The sync value may synchronize timing between at least two base stations of the mobile network. The method may include determining a location of the user equipment based on the sync value and the measurement data. The method may include geometric or linear optimization of the determined location estimate.

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. The next step is applying a force longitudinally to the proximal of the catheter which is sufficient to advance the intradiscal section through the nucleus pulposus and around an inner wall of an annulus fibrosus, but which force is insufficient to puncture the annulus fibrosus. Next the functional element is positioned at a selected location of the disc by advancing or retracting the catheter and optionally twisting the proximal end of the catheter. Then the functional unit treats the annular fissure. Optionally, there is an additional step of adding a substance to seal the fissure. An externally guidable intervertebral disc apparatus also is disclosed.

Parts are provided which combine structural reinforcement of hollow profiles and light weight means of attachment. Optionally, the part may also provide an acoustic baffle. The parts consists of a core coated with expandable structural reinforcing foam on at least part of its surface the core being provided with means for receipt of a nut and means to prevent rotation of the nut. Optionally, a piece of a second expandable material is provided on at least one extremity which can expand to fill the entire cross section of the hollow profile. In a preferred embodiment, the hollow profile is the A, B or C pillar of a vehicle and the nut is used for attaching doors.

An adjustable annuloplasty device is described. In some embodiments, the device includes a body member having a surface that conforms at least partially to a cardiac valve annulus. The body member comprises a shape-memory member that transforms from a first configuration to a second configuration in response to an applied energy. In some embodiments, the device further includes a first electrode assembly, coupled to the shape-memory member, that transfers energy to the shape-memory member, and a second electrode assembly, coupled to the shape-memory member, that transfers at least a portion of the energy away from the shape-memory member.

摘要:
This method of optimizing the quality of a cellular network includes at least one iteration, each iteration comprising: a step of estimating at least one local performance indicator at a plurality of points of the network as a function of parameters of the network; a step of estimating a global quality level of the network for said parameters on the basis of a local quality level as estimated at each of said points and for said parameters, said local quality level depending exclusively on said local performance indicators; said parameters being modified so long as the global quality level can be improved; and a step of storing said parameters corresponding to said optimum global quality level.
摘要:
An intraoperative adjustment device is described. In some embodiments, the device includes an elongate body including a proximal end and a distal end, the distal end configured to penetrate an outer surface of an adjustable cardiac implant implanted in a patient's heart, and the proximal end and the distal end connected by at least one energy-transfer member. In some embodiments, the distal end includes at least one electrode coupled to the energy-transfer member and configured to deliver an activation energy to the adjustable cardiac implant. In some embodiments, the proximal end is configured to attach to an energy source that provides the activation energy. In some embodiments, the proximal end is configured to be located outside the patient's body while the distal end is coupled to the adjustable cardiac implant that is implanted in the patient's heart.
