Malware automated removal system and method using a diagnostic operating system
The present invention automates the operation of multiple malware removal software products using a computerized system that systematically operates the multiple selected software products. These products are executed within a customized Diagnostic Operating System, which is different from the Normal Operating System in which the computer normally operates. Thus, any malware that may be attached to any of the programs, shells, drivers, services, or data files associated with the Normal Operating System cannot corrupt the malware removal process performed under the Diagnostic Operating System. Preferably, the Diagnostic Operating System is accessed from a read-only device prepared on a secure computer separate from the computer that is the target of the malware removal process, and the Diagnostic Operating System executes in a read-only environment. Because many malware removal products rely upon the environment provided by the Normal Operating System, the Diagnostic Operating System must provide redirection to ensure such products perform as expected. Event-triggered redirection of environment variables may be done by either injection of values, or by interception of name/key invocations. |

Deallocation of computer data in a multithreaded computer
An apparatus, program product and method support the deallocation of a data structure in a multithreaded computer without requiring the use of computationally expensive semaphores or spin locks. Specifically, access to a data structure is governed by a shared pointer that, when a request is received to deallocate the data structure, is initially set to a value that indicates to any thread that later accesses the pointer that the data structure is not available. In addition, to address any thread that already holds a copy of the shared pointer, and thus is capable of accessing the data structure via the shared pointer after the initiation of the request, all such threads are monitored to determine whether any thread is still using the shared pointer by determining whether any thread is executing program code that is capable of using the shared pointer to access the data structure. Once this condition is met, it is ensured that no thread can potentially access the data structure via the shared pointer, and as such, the data structure may then be deallocated. |

Iterative reduction of artifacts in computed tomography images using forward projection and an edge-preserving blur filter
We present an iterative method for reducing artifacts in computed tomography (CT) images. First, a filter is applied to the experimental projection data that adaptively expands the detector element size in regions with low photon counts, until the desired number of photons are detected. The initial image is then calculated using an existing reconstruction technique. In each iteration, artifacts and noise in the current image are reduced by using an edge-preserving blur filter. Metal pixels (determined from the initial image) are replaced with smaller values. The resulting image is forward projected. Rays that go through metal are replaced with the forward projected values. Rays that do not pass near metal are kept at the experimental values. Filtered backprojection is then performed on the new projection data to determine the updated image. Finally, after the last iteration, metal pixels are copied from the initial image. |

Adjustable transmitter power for high speed links with constant bit error rate
A method and apparatus for dynamically adjusting power of a transmitter is herein described. A transmitter transmits a pattern to a receiver at a differential voltage. The length of the pattern, in one embodiment, is selected to be a reasonable length training pattern, as not to incur an extremely long training phase.

The differential voltage, where no errors are detected, is scaled by a proportion of a target confidence level to a measured confidence level associated with the reasonable length training pattern. As a result, a training phase is potentially reduced and power is saved while not sacrificing confidence levels in error rates in the data exchange between the transmitter and receiver. |

Plasmon antenna with magnetic core for thermally assisted magnetic recording
A TAMR (Thermal Assisted Magnetic Recording) write head uses the energy of optical-laser generated plasmons in a plasmon antenna to locally heat a magnetic recording medium and reduce its coercivity and magnetic anisotropy.
