Abstract: The subject technology provides a decoding solution that supports multiple choices of code rates. A decoder may be configured to receive a selected code rate from a plurality of code rates. On the selection of the code rate, the decoder may determine a circulant size based on the code rate, and, on receiving the codeword, update, during one or more parity-check operations, a number of confidence values proportional to the circulant size in each of a plurality of memory units, each number of confidence values corresponding to a portion of the codeword.

Abstract: The subject disclosure describes a method for performing error code correction, the method includes, loading a code word including a plurality of encoded bits into a memory array, initializing, into one or more of a plurality of memory units, a plurality of bits associated with each of the encoded bits, wherein the plurality of bits initialized for each of the encoded bits is based on a value of the associated encoded bit and wherein the plurality of encoded bits and the plurality of bits initialized for each of the encoded bits includes soft information. In certain aspects, the method further includes decoding the code word using the soft information and outputting the decoded code word from the memory array. A decoder and flash storage device are also provided.

Abstract: A capsule includes a main body with at least one tail connected to the main body. At least two coils are disposed on each tail such that the coils are responsive to a magnetic field interacting with the coils such that a force is exerted on the tail. The capsule is controlled through application of a varying magnetic field with a constant current in the coils and/or by providing varying a current in the coils that interact with a constant magnetic field. The capsule can be disposed in a cavity, and the magnetic field can be provided from outside the cavity to affect movement of the capsule. An MRI device can be configured to control and image the capsule.

Abstract: A system for combining electromagnetic position and orientation tracking with magnetic resonance scanner is provided. One embodiment includes a magnetic resonance scanner defining a reference coordinate system for scanning a target. Coupled to the magnetic resonance scanner is a magnetic field source which produces a magnetic field. The magnetic field is sensed by a magnetic field sensor which produces a signal proportional to the magnetic field. The magnetic field sensor has a location relative to the reference coordinate system. The location of the magnetic field sensor relative to the reference coordinate system of the magnetic resonance scanner is determined by a location tracking device using at least a line segment model of the magnetic field source and the signal from the magnetic field sensor.

Abstract: The present invention relates to apparatus and a method for imaging and heating body tissues with one probe, through use of a magnetic resonance imaging radio frequency source. The device may also be configured with a thermocouple to provide temperature-controlled heat therapy with sufficient image definition to control that therapy.
