A further coding efficiency increase may be achieved if for a current block of a picture, for which the bit stream signals one of supported partitioning patterns, a reversal of the partitioning by block merging is avoided. In particular, if the signaled one of the supported partitioning patterns specifies a subdivision of the block into two or more further blocks, a removal of certain coding parameter candidates for all further blocks, except a first further block of the further blocks in a coding order, is performed. Particularly, those coding parameter candidates are removed from the set of coding parameter candidates for the respective further block, the coding parameters of which are the same as coding parameters associated with any of the further blocks which, when being merged with the respective further block, would result in one of the supported partitioning pattern. This avoids redundancy between partitioning coding and merging coding.

System and method for atrial autocapture in single-chamber pacemaker modes using far-field detection
InactiveUS6101416AReduce noiseReduce signalingHeart stimulatorsDiagnostic recording/measuringCardiac pacemaker electrodeSingle Chamber Pacemaker
An implantable pacemaker automatically verifies atrial capture and performs atrial stimulation energy assessment when atrial capture is absent. The pacemaker delivers a stimulation pulse in the atrial chamber of the heart and samples the resulting far-field signal from the ventricular chamber during a predetermined far-field interval window. The pacemaker then compares the far-field signal sample to a predetermined far-field signal recognition template. If the far-field signal sample is approximately equal to the far-field signal recognition template, then atrial capture is deemed verified; otherwise, the pacemaker performs an atrial stimulation energy determination. Optionally, the pacemaker automatically determines the timing of the far-field interval window and defines the far-field signal recognition template.

Method of reducing injury to mammalian cells

A method of inhibiting the binding between N-methyl-D-aspartate receptors and neuronal proteins in a neuron is disclosed. The method comprises administering to the neuron an effective inhibiting amount of a peptide replacement agent for the NMDA receptor or neuronal protein interaction domain that effect said inhibition of the NMDA receptor—neuronal protein interaction. The method is of value in reducing the damaging effect of injury to mammalian cells. Postsynaptic density-95 protein (PSD-95) couples neuronal N-methyl-D-aspartate receptors (NMDARs) to pathways mediating excitotoxicity, ischemic and traumatic brain damage. This coupling was disrupted by transducing neurons with peptides that bind to modular domains on either side of the PSD-95 / NMDAR interaction complex. This treatment attenuated downstream NMDAR signaling without blocking NMDAR activity, protected cultured cortical neurons from excitotoxic insults, dramatically reduced cerebral infarction volume in rats subjected to transient focal cerebral ischemia, and traumatic brain injury (TBI) in rats.

A telecommunications system and method is disclosed for reducing the unnecessary signaling for positioning requests involving a Mobile Station (MS) when that MS does not respond to paging requests or is purged from the network, e.g., not registered with a Mobile Switching Center / Visitor Location Register. When a positioning request for a particular MS is received at a serving MSC and the MS does not respond to a paging request, the serving MSC sets a "Subscriber Not Responding to Location Services" (SNRLS) flag, which is used by the serving MSC to avoid unnecessarily sending a new paging request for the same MS. In addition, the serving MSC sends a rejection message to a Gateway Mobile Location Center (GMLC) that sent the positioning request, which includes an unavailable notification indicating that the MS cannot be reached. The GMLC sets an "MS Subscriber Not Present" flag based upon this notification to avoid sending further positioning requests for that MS.

A wireless broadband communications system that can transmit signals over communications links with multiple modes of diversity, thereby allowing signals having very low correlation to propagate over the link along multiple orthogonal paths. The system can be implemented as a non-line-of-sight (NLOS) system or a line-of-sight (LOS) system. The NLOS system employs orthogonal frequency division modulation (OFDM) waveforms to reduce multi-path interference and frequency selective fading, adaptive modulation to assure high data rates in the presence of channel variability, and spectrum management to achieve increased data throughput and link availability. The LOS system employs space-time coding and spatial and polarization diversity to minimize ground bounce nulls. The system achieves levels of link availability, data throughput, and system performance that have heretofore been unattainable in wireless broadband communications systems.
