Abstract:

Methods, systems, and computer program products for transmitting neural signal information. Methods, systems, and computer programs products are disclosed for neural channel selection in a multi-channel system. A method according to one embodiment can include a step for receiving a plurality of neural signals on a first plurality of channels. The method can also include a step for calculating criterion variable value for the neural signal on each of the channels. In addition, the method can include a step for ranking the channels by the criterion variable value. The method can also include a step for calculating mutual information between a measured output and a total population activity for the first plurality of channels. Further, the method can include a step for determining a second plurality of channels that encodes a predetermined amount of the mutual information.

US Classification:

600443, 600461, 128899, 128916

Abstract:

An oscillating shaft is scanned to provide images including the oscillating shaft in vivo in real-time with a real-time three-dimensional (3D) ultrasound scanner. An interventional device can be guided in vivo using an ultrasound scanner and includes a sheath having a bore therethrough from a proximal portion to a spaced-apart distal portion. A shaft has a proximal portion and a spaced-apart distal portion and is configured for insertion into the bore of the sheath. A vibrator is coupled to the proximal portion of the shaft and is configured to cause the distal portion of the shaft to oscillate at a shaft frequency. An isolator is coupled to the proximal portion of the sheath and to the vibrator, wherein the isolator is configured to reduce damping of an oscillation of the shaft by the sheath.

Abstract:

Embodiments of the present invention provide a method, system and computer program product for heap dump object identification in a heap dump analysis tool. In an embodiment of the invention, a method for heap dump object identification in a heap dump analysis tool can be provided. The method can include instrumenting an object with a uniquely identifiable marker, instantiating the instrumented object in a virtual machine executing in memory by a processor of a host computer and triggering a heap dump in the virtual machine. The method also can include parsing a heap dump file resulting from the triggered heap dump to locate a reference to the uniquely identifiable marker. Finally, the method can include displaying an association between the object and the heap dump file in a heap dump analysis tool executing in the memory by the processor of the host computer.
