An elastic structure is introduced percutaneously into the left ventricle and attached to the walls of the ventricle. Over time the structure bonds firmly to the walls via scar tissue formation. The structure helps the ventricle expand and fill with blood during the diastolic period while having little affect on systolic performance. The structure also strengthens the ventricular walls and limits the effects of congestive heart failure, as the maximum expansion of the support structure is limited by flexible or elastic members.

A method and apparatus used in a storage network facilitates the protection of data in, and replacement of, storage devices about to fail before the failure happens. In a network that includes a plurality of sets of storage devices which store respective data sets, a storage device about to fail in one set can be replaced by another storage device from another set of storage devices which is being used to store data having a lower priority. The method comprises assigning priorities to sets of storage devices in the network which store respective data sets. In addition, the method includes detecting a condition of a first particular storage device in a particular set of storage devices that has a first priority. Conditions which are detected according to various embodiments indicate that the first particular storage device is suffering events indicating that it is likely to fail, or otherwise suffering from reduced performance. The conditions are detected for example, by the receipt of a signal from the storage device itself, or by the monitoring of statistics concerning the performance of the storage device. The method further provides for selecting a second particular storage device in a second particular set of storage devices having a second priority, which can be used in place of the first particular storage device. In response to detecting the condition, the data set stored in the first particular storage device is migrated to the second particular storage device, and the second particular storage devices identified as a member of the first particular set. The first particular storage device can be gracefully removed from the network, while only affecting the performance of the data access in the lower priority second particular set of storage devices.

The invention discloses a conducting film which comprises a base sheet, a first conducting layer, a substrate layer and a second conducting layer, wherein the base sheet comprises a first surface and a second surface which is arranged opposite to the first surface, and the first conducting layer is embedded in the base sheet. The substrate layer is attached to the first surface of the base sheet and is formed by curing a jelly like substance coated on the first surface. The second conducting layer is embedded in the substrate layer and is insulated from the first conducting layer by the substrate layer. Due to the fact that capacitance can form between the first conducting layer and the second conducting layer, when the conducting film is used for manufacturing a touch screen, two conducting films do not need to be combined together in a bonding mode, and all that is needed is to attach the conducting film to a glass panel. In addition, the substrate layer is formed by curing the jelly like substance coated on the base sheet, the thickness is far smaller than that of the base sheet, and therefore the touch screen made of the conducting film has a quite small thickness. Moreover, the invention further provides a preparation method of the conducting film and the touch screen comprising the conducting film.

The terminal helical loop can have a J-shaped configuration, preferably with a loop diameter of about 2 mm. The coil is preferably provided with helical loops at both ends, with helical loop at the proximal and distal ends of the coil acting as an anchor to prevent the coil from coming free from the location being treated and escaping into the vasculature. In a presently preferred embodiment both ends of the coil have a J-shape. In another presently preferred aspect, the vasoocclusive coil includes one or more loops intermediate the ends of the coil. The device is formed from a multi-stranded micro-cable having a plurality of flexible strands of a shape memory material and at least one radiopaque strand. The strands can be made of a shape memory nickel titanium alloy, that is highly flexible at a temperature appropriate for introduction into the body via a catheter, and that after placement will take on the therapeutic shape.

Improved method of encoding and repairing data for reliable storage and transmission using erasure codes, which is efficient enough for implementation in software as well as hardware. A systematic linear coding matrix over GF(2^q) is used which combines parity for fast correction of single erasures with the capability of correcting k erasures. Finite field operations involving the coding and repair matrices are redefined to consist of bitwise XOR operations on words of arbitrary length. The elements of the matrix are selected to reduce the number of XOR operations needed and buffers are aligned for optimal processor cache efficiency. Decode latency is reduced by pre-calculating repair matrices, storing them in a hashed table and looking them up using a bit mask identifying the erasures to be repaired.

An approach is provided for generating Low Density Parity Check (LDPC) codes. An LDPC encoder generates a LDPC code with an outer Bose Chaudhuri Hocquenghem (BCH) code. For a rate 3/5 code, the approach provides a degree profile that yields reduced memory requirements for storage of the edge values without significantly affecting the performance with respect to an “unmodified” rate 3/5 code. The relevant parameters for the reduced memory LDPC codes are as follows: q=72, n_ldpc=64800, k_ldpc=n_BCH=38880, k_BCH=38688. The above approach has particular application in digital video broadcast services over satellite.

Methods and apparatus for improving the sensing performance of a capacitive touch screen sensing device. The electrical potential of conductive structures proximate capacitive touch pads of the sensing device is altered to compensate for the effect of parasitic capacitance, based on external conditions such as water on the touch screen or an intervening user worn glove. The compensation for parasitic capacitance improves the signal to noise ratio and therefore the sensing performance of the device.
