Title: Heuristic-based conditional data indexing
Inventor: MCARTHUR CATHERINE S
IPC: G06F17/30
Filed: 1999-07-29
Granted: 2004-10-19
Abstract: A computer system for the indexing of data in which a heuristic determination function is applied to predict an efficient index updating approach. The system is able to update an index relating to a first data set by incrementally updating the index or by a rebuild of the index at the completion of the addition of a second set of data to the first set of data. The system applies a heuristic determination function to the characteristics of the first set of data, its index, and the second set of data, to predict whether an incremental update or a rebuild update of the index will result in a more efficient rebuild of the data. The system applies this approach to a restore and rollforward recovery or a data load operation to improve the efficiency of these operations.

Title: Syndecan interacting proteins and the use thereof
Inventor: ZIMMERMANN PASCALE
IPC: C12Q1/68
Filed: 1998-04-22
Granted: 2003-10-14
Abstract: The invention relates to the identification of a protein that binds to the cytoplasmic domain of the syndecan. This protein, now called syntenin, contains a tandem repeat of PDZ-domains that reacts with the FYA C-terminal amino acid sequence of the syndecans (Trends Biochem.Sci., 20, p. 350, 1995: Origin of PDZ {DHR, GLGF}, by M.B. Kennedy). Endogenous syntenin appears to be localized to the cytoskeleton. GFP-syntenin fusion-proteins decorate the plasma membrane and intracellular vesicles, where they co-localize and - segregate with syndecan cytoplasmic domains. Syntenin, therefore, is an unexpected candidate for connecting the cytoskeleton to heparan sulfate- assisted signal transduction pathways. The syndecan cytoplasmatic link (sycl ) protein or syndecan interacting protein is referred to by the name "syntenin ", meaning "putting tension on the syndecans".

Title: Linear low noise phase locked loop frequency synthesizer using controlled divider pulse widths
Inventor: RILEY THOMAS
IPC: H03L7/087
Filed: 2000-01-06
Granted: 2004-03-30
Abstract: A method and an apparatus relating to a PLL circuit for frequency synthesizer applications. By using a composite PFD large and small phase variations between a reference signal and the divider output are compensated for. The composite phase frequency detector (PFD) has both a digital phase frequency detector (digital PFD) and an analog phase detector (analog PD) with the digital FFD compensating for large phase differences and the analog PD compensating for smaller phase differences. The PLL automatically chooses between these two components in the composite PFD by controlling the pulse width of the divider output. This is accomplished by synchronizing the dead zone of the digital PFD with the active pulse width of the divider output and by similarly synchronizing the phase detector window of the analog PD to be within both the dead zone of the digital PFD and the active pulse width of the divider output. Thus, during the active pulse of the divider output, the analog PD is operative while during the inactive pulse the digital PFD is operative. By essentially having only one PD active at any time, problems with analog/digital mixed circuits are avoided.
