Flash memory controller to perform delegated move to host-specified destination
This disclosure provides for host-controller cooperation in managing NAND flash memory. The controller maintains information for each erase unit which tracks memory usage. This information assists the host in making decisions about specific operations, for example, initiating garbage collection, space reclamation, wear leveling or other operations.

Resiliency to memory failures in computer systems
A resiliency system detects and corrects memory errors reported by a memory system of a computing system using previously stored error correction information. When a program stores data into a memory location, the resiliency system executing on the computing system generates and stores error correction information. When the program then executes a load instruction to retrieve the data from the memory location, the load instruction completes normally if there is no memory error. If, however, there is a memory error, the computing system passes control to the resiliency system (e.g., via a trap) to handle the memory error. The resiliency system retrieves the error correction information for the memory location and re-creates the data of the memory location. The resiliency system stores the data as if the load instruction had completed normally and passes control to the next instruction of the program. |

Method and kit for immunological detection of Mycobacterium tuberculosis complex
Definitive diagnosis and early start of treatment cannot be made for tuberculosis since conventional methods for detecting a Mycobacterium tuberculosis complex require a long time plus enormous labor and expense. Because detection is difficult to perform directly from a biological sample, if the biological sample contains no or a very small amount of the Mycobacterium tuberculosis complex-specific secretory protein, there is a risk infection with the Mycobacterium tuberculosis complex will be missed. The present method and a kit address these long-standing needs by more rapidly and conveniently detecting a Mycobacterium tuberculosis complex, without culturing a biological sample containing the Mycobacterium tuberculosis complex, in which a biological sample is subjected to a heat-treatment so as to extracellularly secrete a Mycobacterium tuberculosis complex-specific secretory protein, such as at least one of MPB70, ESAT-6, or CFP-10 and subjecting the resulting treated sample to an immunological measurement/assay. |

Method for environmental analysis and control of spatial areas
The goal of the METHOD FOR ENVIRONMENTAL ANALYSIS AND CONTROL OF SPATIAL AREAS as a continuation of “The Spatial Environmental Control Unit” is a method of logging multi-spectral, multi-pixel infrared radiation data of objects in a spatial area for the analysis and control of heat transfer dynamics in the spatial area that is responsive to feedback for controlling the thermal conditions in the spatial area. The METHOD FOR ENVIRONMENTAL ANALYSIS AND CONTROL OF SPATIAL AREAS further makes the current norm of an “absolute” temperature control approach for thermal control and human comfort obsolete. Ambient environmental conditions and user preference variables makes the current approach to thermal control time consuming, inaccurate and tedious. The Spatial Environmental Control Unit as one of our foundation patents disclosed the physical components make thermal control and analysis more responsive and user friendly. The METHOD FOR ENVIRONMENTAL ANALYSIS AND CONTROL OF SPATIAL AREAS makes the control and analysis of the thermal properties of the spatial area more intuitive by providing visual images on any compatible device simplifying the understanding of the dynamics of heat transfer in an environment. Tedium and frustration become understanding and empowerment. This method enables gaining knowledge and using tools for analysis, allowing a user to “redesign” his environment by correcting ambient conditions and improving the operation of the thermal conditioning equipment. The end result is a better thermal environment with higher energy efficiency. |

Tapered roller bearing
A tapered roller bearing includes a cage supporting a plurality of tapered rollers. The cage includes a large-diameter annular portion; a small-diameter annular portion; pillars through which the large-diameter annular portion and the small-diameter annular portion are coupled together; and pockets in which the respective tapered rollers are disposed. A space is defined between the outer ring and the inner ring, and constitutes an oil flow path through which lubricating oil (a) flows from the side of the small flange to the side of the large flange. Each pillar includes, in its radially inner surface, an oil groove in which lubricating oil is retained. When the cage rotates, the lubricating oil retained in the oil grooves of the pillars is scattered out of the oil grooves, thereby preventing seizure between the large-diameter end surfaces of the tapered rollers and the large flange of the inner ring. |

Wire thread insert with redressable mounting tang as well as its manufacturing and installation
A wire thread insert comprises besides a cylindrical helix consisting of a plurality of coils a moving tang projecting into the interior of the helix for installing the wire thread insert into a receiving thread. The wire thread insert is connected to the cylindrical helix via a bending portion such that the moving tang can be redressed into the receiving thread after installation of the wire thread insert. The wire thread insert is installed by means of an installation tool with a mounting spindle, which installs the wire thread insert in the receiving thread via a moving shoulder and the moving tang. A compression blade provided at the mounting spindle bends the moving tang back into the receiving thread while the mounting spindle is removed from the installed wire thread insert. |

Two-stage rotary compressor
The present disclosure relates to a two-stage rotary compressor in which refrigerant inhaled into a compression space of a cylinder is compressed sequentially in two axially connected compression chambers and then is discharged. A rotary compressor according to an embodiment of the present disclosure includes a first compression unit and a second compression unit arranged on and along a single rotation shaft. Middle-pressure refrigerant discharged from the first compression unit flows into the second compression unit. A maximum gas force of the first compression unit and a maximum gas force of the second compression unit counteract with each other, thereby reducing a reaction force acting on a rotation shaft. According to the present disclosure, a single rotary compressor is configured to separately achieve the stroke volume increase and the compression period increase. |
