摘要:
A data storage and retrieval device and method is disclosed. The device includes at least one magnetic storage medium configured to store target data and at least one re-configurable logic device comprising an FPGA coupled to the at least one magnetic storage medium and configured to read a continuous stream of target data therefrom, having been configured with a template or as otherwise desired to fit the type of search and data being searched. The re-configurable logic device is configured to receive at least one search inquiry in the form of a data key and to determine a match between the data key and the target data as it is being read from the at least one magnetic storage medium. This device and method can perform a variety of searches on the target data including without limitation exact and approximate match searches, sequence match searches, image match searches and data reduction searches. This device and method may be provided as part of a stand-alone computer system, embodied in a network attached storage device, or can otherwise be provided as part of a computer LAN or WAN. In addition to performing search and data reduction operations, this device may also be used to perform a variety of other processing operations including encryption, decryption, compression, decompression, and combinations thereof.

A firmware socket module is deployed on a reconfigurable logic device, wherein the firmware socket module has a communication path between itself and an entry point into a data processing pipeline, wherein the firmware socket module is configured to provide both commands and target data to the entry point in the data processing pipeline via the same communication path, wherein each command defines a data processing operation that is to be performed by the data processing pipeline, and wherein the target data corresponds to the data upon which the data processing pipeline performs its commanded data processing operation. Preferably, the firmware socket module is configured to provide the commands and target data in a predetermined order that is maintained throughout the data processing pipeline. Also, the firmware socket module may be configured to (1) access an external input descriptor pool buffer that defines the order in which commands and target data are to be provided to the data processing pipeline, and (2) transfer the commands and target data from an external memory to the data processing pipeline in accordance with the identified defined order. Results of the processing by the data processing pipeline are also returned to external memory by the firmware socket module, whereupon those results can be subsequently used by software executing on a computer system.

An encryption technique is disclosed for encrypting a data segment comprising a plurality of data blocks, wherein the security and throughput of the encryption is enhanced by using blockwise independent bit vectors for reversible combination with the data blocks prior to key encryption. Preferably, the blockwise independent bit vectors are derived from a data tag associated with the data segment. Several embodiments are disclosed for generating these blockwise independent bit vectors. In a preferred embodiment, the data tag comprises a logical block address (LBA) for the data segment. Also disclosed herein is a corresponding decryption technique as well as a corresponding symmetrical encryption/decryption technique.

The progress of a endovascular aneurysm repair can be monitored by inserting a pressure transducer sensor using a catheter into the sac during endovascular aneurysm repair and then using a small, hand-held read out device to measure pressure easily, safely, inexpensively and accurately. In one aspect a sensor is introduced into the body by the steps of folding or rolling the sensor into a cylinder, loading it into a catheter, and deploying into the aneurysm sac by allowing it to unroll or unfold, either by itself or facilitated by the incorporation of a super-elastic alloy component.

In the disclosed method of manufacturing an implantable wireless sensor, a cavity is etched in one side of a first substrate. A conductive structure are formed on the base of the cavity. A second conductive structureare formed on a surface of a second substrate, and the two substrates are mutually imposed such that the two conductive plates and coils are disposed in opposed, spaced-apart relation. A laser is then used to cut away perimeter portions of the imposed substrates and simultaneously to heat bond the two substrates together such that the cavity in the first substrate is hermetically sealed.

An integrated gaming and media experience is disclosed, including recording of content on a gaming console. A digital video recorder (DVR) application running alongside a television client component allows users to record media content on the gaming console. The DVR application also integrates itself with the console menu. Once integrated, users can record media content while playing games. Alternatively, users can record content when the gaming console is turned off. The recorded content can include television programming, gaming experience (whether local or online), music, DVDs, and so on. When in the recording state, users can also switch between various other media modes, whether gaming, television, and so on.
摘要:
A method for measuring pressure within a heart includes the steps of: (1) providing a passive wireless pressure sensor having a characteristic impedance and a deflectable surface, the characteristic impedance changing in response to deflection of the deflectable surface; (2) inserting the sensor to a location within the body of a patient at which the sensor can detect pressure within the heart; (3) affixing the sensor relative to the heart; (4) interrogating the sensor with an electromagnetic field; (5) receiving a signal from the sensor corresponding to a sensed pressure; and (6) leaving the sensor in situ so that future pressure measurements can be made.
