Assured archival and retrieval system for digital intellectual property

A system and method of use for permanently archiving intellectual properties (IP) in a digital archival system. An owner contributes each IP with an initial financial contribution including a discrete archival endowment which is sufficient to fund archival of the IP for an assured archival period. A plurality of discrete archival endowments can be pooled into one or more archival endowment funds, jointly managed for the maintenance of each archived IP. The endowment funds can be managed by a trustee separate from the management of the digital archive. Retrieval can be funded through retrieval fees or an endowment maintained separate from the archival endowment fund. Digital rights management can remunerate owners and revenue tracking can capitalize the value of each IP. Access to the archive system is preferably through a variety of membership options including owners, users, and partners.

Compensation of motion in a moving organ using an internal position reference sensor

An apparatus for displaying a moving region of interest located within a body includes a positioning system to determine a position and orientation (P&O) of a medical device as well as to track, using an internal position reference sensor, the motion of the region of interest over time. A compensation function block generates a motion compensation function based on the motion of the region of interest, which is configured to compensate for the motion of the region of interest between a first time, for example a time at which an image was acquired and a second time, for example a time at which a P&O of the device was measured. The measured P&O is corrected using the compensation function. A representation of the medical device is superimposed on the image in accordance with the corrected P&O.

Four motion vector coding and decoding in bi-directionally predicted interlaced pictures

For interlaced B-fields or interlaced B-frames, an encoder / decoder uses 4MV coding. For example, 4MV is used in one-direction prediction modes (forward or backward modes), but not in other available prediction modes (e.g., direct, interpolated). Using 4MV allows more accurate motion compensation for interlaced B-fields and interlaced B-frames; limiting 4MV to forward and backward modes reduces coding overhead and avoids decoding complexity associated with combining 4MV with modes such as direct and interpolated.

Repeatable runout (RRO) compensation methods and apparatus for data storage devices

In one illustrative example, a method for use in reducing Repeatable Run Out (RRO) error in a data storage device involves obtaining an RRO measurement for each track of a limited number of N disk tracks; characterizing the RRO measurement for each track with real and imaginary values by performing a discrete Fourier transform (DFT) calculation on each RRO measurement; performing a least-squares fit on all of the real values to identify a first set of (n+1) coefficients of an nth-order polynomial function which is a function of disk track r and representable in the form Ai(r)=anrn+a(n−1)r(n−1)+ . . . +a1r+a0; and performing a least-squares fit on all of the imaginary values to identify a second set of (n+1) coefficients of an nth-order polynomial function which is a function of disk track r and representable in the form Bi(r)=bnrn+b(n−1)r(n−1)+ . . . +b1r+b0. RRO compensation is performed based on the relation DRRO(r, s)=Σi for all H {Ai(r)cos(i(s2π / total_sectors))+Bi(r)sin(i(s2π / total_sectors))} where DRRO is the estimated RRO error; r is a track number; s is a sector number at track number r; i is an RRO harmonic number; H is a set of harmonics to be compensated; and total_sectors is a total number of sectors along track number r. Advantageously, RRO variations across the disk can be accurately compensated for with use of a small amount of memory.
