Method for Non-Volatile Memory with Background Data Latch Caching During Read Operations
ActiveUS20060221696A1Minimize perturbationSave transfer timeMemory architecture accessing/allocationRead-only memoriesTransfer operationNon-volatile memory
Part of the latency from memory read or write operations is for data to be input to or output from the data latches of the memory via an I / O bus. Methods and circuitry are present for improving performance in non-volatile memory devices by allowing the memory to perform some of these data caching and transfer operations in the background while the memory core is busy with a read operation. A scheme for caching read data is implemented so that even when the read for a current page on a current wordline must be preceded by a prerequisite read of data on an adjacent wordline, the prerequisite read along with any I / O access is preemptively done in the cycle for reading a previous page so that the current read can be performed while the previously read page is busy with the I / O access.

Mattress Protection
The present invention seeks to address the chronic and worsening problem of mattress management in hospitals by providing a mattress protector to shield a mattress or mattress core from body fluids, the protector not only comprising a shielding cover for the mattress or mattress core but also a detector in an inter- or under-layer of the cover to detect body fluid that has passed into or through the cover. The detector may be chemical, with the cover being a transparent cover and the under-layer being absorbent and having a dye that is activated by a body fluid to provide a visual indication of presence of the body fluid. In an alternative embodiment the detector may be an apparatus monitoring electrical conductivity. This suitably uses threads of electrically conductive yarn forming either the warp or weft of a thin flexible under layer of the protective cover and which are linked to a small processor which monitors the electrical conductivity between neighbouring conductive threads in the sensing layer.

A KE rod warhead for artillery rockets contains a multiplicity of KE rod penetrators housed in trays and packaged into bays or tier packs that are stacked and positioned around a center column of the warhead. The warhead has a skin which is severed upon the rocket entering a target area. The KE rods are situated and housed in such a manner that upon release the rods experience a minimum of pitching or tumbling upon entering the air stream giving the rods an optimal lethality against a designated target. The KE rod artillery rocket contains no explosive munitions, so it can be used without civilian and environmental concerns over unexploded ordnance.
