Non-Volatile Memory And Method With Post-Write Read And Adaptive Re-Write To Manage Errors
ActiveUS20110099460A1Small marginImprove performanceMemory loss protectionRead-only memoriesHigh densityLow density
Data errors in non-volatile memory inevitably increase with usage and with higher density of bits stored per cell. The memory is configured to have a first portion operating with less error but of lower density storage, and a second portion operating with a higher density but less robust storage. Input data is written and staged in the first portion before being copied to the second portion. An error management provides checking the quality of the copied data for excessive error bits. The copying and checking are repeated on a different location in the second portion until either a predetermined quality is satisfied or the number or repeats exceeds a predetermined limit. The error management is not started when a memory is new with little or no errors, but started after the memory has aged to a predetermined amount as determined by the number of erase / program cycling its has experienced.

Data errors in non-volatile memory inevitably increase with usage and with higher density of bits stored per cell. The memory is configured to have a first portion operating with less error but of lower density storage, and a second portion operating with a higher density but less robust storage. An error management provides reading and checking the copy after copying to the second portion. If the copy has excessive error bits, it is repeated in a different location either in the second or first portion. The reading and checking of the copy is accelerated by reading only a sample of it. The sample is selected from a subset of the copy having its own ECC and estimated to represent a worst error rate among the copy it is sampling. One embodiment has the sample taken from one bit of each multi-bit memory cell of a group.

Non-Volatile Memory And Method With Post-Write Read And Adaptive Re-Write To Manage Errors
ActiveUS20110099418A1Small marginReduce memory costMemory adressing/allocation/relocationRead-only memoriesHigh densityQuality assurance
Data errors in non-volatile memory inevitably increase with usage and with higher density of bits stored per cell. For acceptable quality assurance, conventional error correction codes (“ECC”) have to correct a maximum number of error bits up to the far tail end of a statistical population. The present memory is configured to have a first portion operating with less error but of lower density storage, and a second portion operating with a higher density but less robust storage. If excessive error bits (at the far tail-end) occur after writing a group of data to the second portion, the data is adaptively rewritten to the first portion which will produce less error bits. Preferably, the data is initially written to a cache also in the first portion to provide source data for any rewrites. Thus, a more efficient ECC not requiring to correcting for the far tail end can be used.

A method and apparatus relating to a biocompatible soft tissue implant is disclosed. The implant, in the form of a prosthesis, is constructed of a knitted pile mesh material arranged into either a 3-dimensional structure or a planar shape or structure. The material or fabric includes a plurality of filament extensions projecting outwardly therefrom. The filament extensions can be radially projecting looping filaments from one or more rows of the knitted pile mesh material. The combination of the filament extensions with the 3-dimensional structure results in the biocompatible implant having a structural resistance to hinder anticipated crushing forces applied to the implant, and also provide a suitable 3-dimensional structure for promoting rapid tissue in-growth to anchor such implant without migration and strengthen the repaired tissue area.

An improved fire alarm system capable of reliably detecting the presence of fire caused by different sources. The fire alarm system detects a smoke density (S) as well as a temperature difference (DELTAT) within a predetermined time interval, and has primary criteria of (i) whether the smoke density (S) exceeds a smoke threshold [e.g., S>5% / m]; (ii) whether the temperature difference (DELTAT) exceeds a temperature difference threshold [e.g., DELTAT>=18 C]; and (iii) whether a combination of S and DELTAT satisfies an inequality [e.g. 2S+DELTAT >=12] which is based upon a decreasing function of DELTAT with an increase of S. The detected smoke density and the temperature difference are examined with reference to the primary criteria so as to provide a fire warning signal indicating a possible fire presence when anyone of the above primary criteria is satisfied.

Automated visual inspection system for the detection of microbial growth in solutions
ActiveUS20060072111A1Easy to adjustLess optical densityOptically investigating flaws/contaminationParticle size analysisNon destructiveVisual inspection
Essential prerequisites for any injectable product are its sterility, its freedom from pathogens and its freedom from visible particle contamination . . . . These requirements must be satisfied prior to the release of an injectable product batch for sale and use. A major difficulty in responding to these assay requirements is the need for a size sensitivity difference of 100 or greater in determining the presence of viable pathogenic organisms and of non-viable random particle contaminants. The wide dynamic testing range cannot be satisfied in current art with a single non-destructive testing station. The present invention uses a special agitation procedure to generate separate liquid volumes containing the small viable and larger non-viable particle contaminants. This separation makes possible the introduction of sensing systems that have been optimized for each size range and that can operate in parallel without interference.

A permanent magnet generator having the unique feature of a speed proportionally adjusted air gap for self-regulation of coil output voltage over a wide range of operating rotational speed of a steam turbine to which the invention is coupled. The Permanent Magnet Generator rotor is supported by the turbine end shaft and the stator is supported by a bracket bolted to the turbine pedestal base or other rigid structure. The speed proportional air gap is accomplished through the use of a plurality of centrifugal flyweights in mechanical coupling to a spool piece under spring load and to corresponding rare earth magnets via linkage such that increasing rotor speed extends the flyweights outward from the rotor center of rotation and draws the rare earth magnets closer to the rotor center of rotation and thus increases the air gap.

Neutrally buoyant submerged system using lesser density ballast fluid
InactiveUS7987805B1Avoid excessive densityVessel partsVessel safetyMarine engineeringNeutral buoyancy
The invention provides a means by which the attitude or orientation of a submerged object can be changed or altered using a fixed quantity of transferable ballast fluid which has a density less than that of the surrounding fluid in which the object is submerged. In one embodiment, the process utilizes a static negatively buoyant material (which could be a lead weight) to offset the net negative buoyancy of the transferable ballast fluid. In this way, the total overall buoyancy of the system does not change, but by transferring ballast fluid into expandable reservoirs which are physically separated from the static negatively buoyant material, the separation between the center of buoyancy and the center of mass of the object can be changed, and thus the attitude or orientation of the object, if it is unrestrained, may be changed.
