摘要:
The described subject matter relates to an architecture that can dynamically detect and/or automatically remedy service usage inequities in a communications network. In particular, based upon a comparison of incoming call detail records (CDRs) to various subscriber information (e.g., service plan, blacklisted devices for the service plan, historic or current billing cycle usage, etc.), the architecture can identify when a usage inequity occurs or is likely to occur, substantially in real time.

Group IV nanocrystals, such as, for example, silicon nanocrysals and germanium nanocrystals, with chemically accessible surfaces are produced in solution reactions. Group IV halides can be reduced in organic solvents such as 1,2-dimethoxyethane (glyme), with soluable reducing agents to give halide-terminated group IV nanocrystals, which can then be easily functionalized with alkyl lithium, Grignard or other reagents to synthesize group IV nanocrystals having air and moisture stable surfaces. Synthesis can occur at ambient temperature and pressure.

摘要:
A method and system or determining a flight path for an aircraft between an initial point and a destination point are described. An airspace is divide into a set of grid cells, and a flight path is established between the initial point and the destination point. A cumulative threat risk value for each of the grid cells is calculated, and an allowable threat risk per grid cell is established based on a rule set. An intermediate point from which to deviate the flight path is identified based upon an analysis of the cumulative threat risk values of the grid cells, if the threat risk value of any of the grid cells intersecting the flight path exceeds the allowable threat risk. A deviation from the intermediate point to a new intermediate point is determined such that the new intermediate point has a cumulative threat risk value lower than or equal to the allowable threat risk per grid cell. The flight path is adjusted between the initial point and the destination point to pass through the new intermediate point, thereby providing a modified flight path.

In some embodiments, a module may have a slot for an input/output card. While cables may be connected to the card in the module, external forces acting on the cable and/or module may result in the cable pulling the card out of the module, damaging the connector or card. In some embodiments, a strain-relieving device may be used to counter these forces on the cable. In some embodiments, a positioning strip may be coupled to a base placed over the card in the module. In some embodiments, a cable grip may be coupled to the positioning strip through a bracket. In some embodiments, the cable grip may include two plates that are coupled to the bracket through fasteners. As the fasteners are tightened, a distance between the two plates may decrease, and a cable between the plates may be at least partially secured between the plates.

A method and apparatus for selecting an antenna mapping in multiple-in/multiple-out (MIMO) enabled wireless communication networks. A candidate set of currently available antenna mappings is determined based upon measured long term channel conditions. An antenna mapping is selected from the candidate set, and the mapping is calibrated with a selected antenna mapping of a receiving wireless transmit/receive unit (WTRU). When the selected mappings are calibrated, packet data transmission begins. In an alternative embodiment, a calibration training frame (CTF) is used to calibrate multiple antenna mappings simultaneously or sequentially. Also disclosed are physical layer and medium access control layer frame formats for implementing antenna mapping selection according to the invention.
摘要:
A fault interrupter having a microcontroller is provided to detect actual faults. The fault interrupter initiates a periodic self-test and provides external notification to the user upon successful or unsuccessful completion of the test. The fault interrupter generates the test signal at a selected time to substantially coincide with the zero-crossing of the AC power source. A manual test can also be performed using a manual test switch provided as a direct input to the microcontroller.

A hand and foot shovel which comprises an elongated handle, a metal spade, a hand end cap, a first foot pad and a second foot pad. The elongated handle is designed to relieve unnecessary pressure on the back during the digging and lifting process. The first and second foot pads are operable to assist in the digging process by allowing for additional leverage without bending or be required to get into the hole depending upon the depth that is being dug.
摘要:
A structure may be coupled to an adapter coupling two or more modules together. In some embodiments, the structure may direct air and/or dissipate heat from the modules into the air. The structures may direct air to components on a module that might receive less airflow without the structures. In some embodiments, the structure may be coupled to the adapter through a fastener (e.g., multiple structures may be manufactured with a plate, and the plate may be coupled to the adapter). In some embodiments, thermally conductive pathways may be used on the modules to conduct heat from components on the modules to a heat dissipating structure on the adapter.
摘要:
Silicon nanocrystals with chemically accessible surfaces are produced in solution in high yield. Silicon tetrahalide such as silicon tetrachloride (SiCl4) can be reduced in organic solvents, such as 1,2-dimethoxyethane(glyme), with soluble reducing agents, such as sodium naphthalenide, to give halide-terminated (e.g., chloride-terminated) silicon nanocrystals, which can then be easily functionalized with alkyl lithium, Grignard or other reagents to give easily processed silicon nanocrystals with an air and moisture stable surface. The synthesis can be used to prepare alkyl-terminated nanocrystals at ambient temperature and pressure in high yield. The two-step process allows a wide range of surface functionality.
