摘要:
Multiple instances of operating systems execute cooperatively in a single multiprocessor computer wherein all processors and resources are electrically connected together. The single physical machine with multiple physical processors and resources is subdivided by software into multiple partitions, each with the ability to run a distinct copy, or instance, of an operating system. At different times, different operating system instances may be loaded on a given partition. Resources, such as CPUs and memory, can be dynamically assigned to different partitions and used by instances of operating systems running within the machine by modifying the configuration. The partitions themselves can also be changed without rebooting the system by modifying the configuration tree. A grouping of partitions, a community, shares memory. Memory may be private to a particular partition or may be shared by partitions within a community. When a community is formed the creating instance reads a configuration tree and builds management structures for the shared memory owned by the community. A single system may have one or more communities, each with their own representation within the configuration tree.

Apparatus, methods, and other embodiments for fifth wheel hitch assemblies are described herein. In one embodiment, a remotely controlled fifth wheel hitch assembly comprises a mounting rail, a head assembly, a locking arm, an actuation mechanism, and a remote control device. The mounting rail is coupled to a towing vehicle and the head assembly is slidably coupled to the mounting rail. The head assembly is capable of securing a trailer to the towing vehicle. The locking arm includes a locked position and an unlocked position. In the locked position, the head assembly is statically secured to the mounting rail. The actuation mechanism is coupled to the locking arm to move the locking arm between the locked and unlocked positions. The remote control device is coupled to the actuation mechanism such that the remote control initiates the actuation mechanism to move the locking arm between the locked and unlocked positions.

A storage system includes at least one storage medium having a label, the label having a width extending along a first axis. The tape storage system further includes a reader to read the label based on light scanned across the label, where the reader has a light sensing portion extending along a second axis that is inclined with respect to the first axis.

An in vitro method of determining an analyte concentration of a sample includes placing the sample into a low-field, bench-top time-domain nuclear magnetic resonance (TD-NMR) spectrometer. The NMR spectrometer is tuned to measure a selected type of atom. A magnetic field is applied to the sample using a fixed, permanent magnet. At least one 90 degree radio-frequency pulse is applied to the sample. The radio-frequency pulse is generally perpendicular to the magnetic field. The 90 degree radio-frequency pulse is removed from the sample so as to produce a decaying NMR signal. The decaying NMR signal is measured at a plurality of times while applying a plurality of 180 degree refocusing radio-frequency pulses to the sample. The analyte concentration is calculated from the plurality of measurements associated with the decaying NMR signal and a selected model.
