Logging events with timestamps
A logging unit is used to log entries for events in a computer system. Each entry includes an n-bit timestamp field and a payload. The payload includes information about the event and the timestamp field includes the n least significant bits of an N-bit timestamp for the event, where N>n.

Therefore, an N-bit timestamp can be determined for an event, but only the n least significant bits of the timestamp are stored in the timestamp field of an entry for the event. Therefore, the time flow of events in the store is better maintained (by having a larger timestamp) without increasing the number of bits (n) in the timestamp field of each entry. |

Delayed data release after programming to reduce read errors in memory
A memory device and associated techniques avoid reading memory cells immediately after programming when uncorrectable errors may be present. In one aspect, data is copied from one block to another block and a timer is started after the copying is completed. If a read command is received before the timer has expired, the read operation proceeds by reading the one block. If the read command is received after the timer has expired, the read operation proceeds by reading the another block. This approach is particular suitable when data is copied from single-level cell (SLC) blocks to multi-level cell (MLC) blocks in a folding operation. The duration of the timer can be increased at lower temperatures. |

High resolution and high sensitivity three-dimensional (3D) cursor maneuvering device
A three dimensional (3D) maneuvering device generates 3D data by irradiating a variably tinted two dimensional (2D) reference surface. The tri-stimuli color index data (e.g. CIE 1931 RGB) is a reliable and high definition source of such tinting. By mathematical conversion, the color index data on the 2D surface is mapped into 3D positional data, i.e. (x, y, z) to be used by a computer, a 3D rendering device or an electronic or electromechanical device such as a 3D printer. The 3D maneuvering device has high sensitivity, high resolution, and immunity from the noise caused by human vibrations. A rotational motion vector is derived by comparing the relative motion vectors derived from a pattern recognition process of surface features on the same reference plane with the positional data derived using the color index data. Thus, a single gestural movement of the operator's hand provides both the translational and rotational motion data simultaneously. |

Penetrating fixture and fiberglass sump
A fluorine gas functionalized surface of a fixture is chemically bonded to a fiberglass sump using a resin. The resin chemically reacts with the functionalized surface creating a strong, chemical bond between the fixture, which penetrates the shell of the sump, and the fiberglass shell of the sump. For example, the surface of the fixture is functionalized by a fluorine-containing gas mixture in an autoclave at a temperature, pressure and duration that creates C═O double bonds at the surface of a polyethylene fixture. The resin chemically reacts with the C═O double bonds and bonds with a fiberglass transition fitting capable of being joined to the shell of the sump. |

Integrated immersed tube coupling and installation method thereof as well as installation closure method of immersed tube coupling
The present application discloses an integrated immersed tube section and an installation method thereof, and an installation and closure method of immersed tube sections, wherein the integrated immersed tube section includes a standard immersed tube section; and closed annular telescopic water stop joints are arranged at two ends of the standard immersed tube section. By the adoption of the integrated immersed tube section of the present application, a finally closed immersed tube section is still the standard immersed tube section, and a foundation which is the same as that for common tube sections is used, namely the foundation for the finally closed immersed tube section and the foundation for other immersed tube sections do not have a rigidity difference, so that the risk of the non-uniform settlement of the tube sections during operation of the subsea tunnel is effectively reduced; and in addition, the finally closed immersed tube section and other immersed tube sections are installed with the same installation equipment, and no extra equipment such as a floating crane is needed. Compared with an existing method, the methods have the advantages of eliminating installation of one special final joint, simplifying the construction process and reducing the engineering risk. As offshore special construction equipment and ships are very expensive in rent, use of the integrated immersed tube section substantially reduces the cost and saves various resources. |

Flow control valve with eddy current dampening
A valve is provided having an inlet to receive a flowable particulate media and an outlet to dispense the media. The valve has an inlet portion with a funnel and repelling magnets. A shuttle sleeve extends from the inlet portion to allow a shuttle to slide along a central axis between an opened and a closed position. The shuttle has shuttle magnets that are oriented to have poles that face the repelling magnets to create a biasing force that biases the shuttle towards the closed position. When the shuttle moves, the shuttle magnets create eddy currents in a tube. The closed position is defined by a sealing edge of the shuttle contacting a sealing surface on a flow director. A capacitive sensor surrounds the flow director to measure the amount of media that is dispensed by the valve. |
