摘要:
A busway fitting wherein the switch and/or fuse are disposed in a horizontal orientation. As the switch assembly and/or fuse are disposed in a horizontal orientation, the buses coupled to the switch assembly and/or fuse also extend horizontally. As such, the buses coupled to the switch assembly and/or fuse occupy a reduced amount of space. In this configuration, the transition buses may extend in a generally horizontal direction and such, the size of the busway fitting may be reduced.

A negative stiffness device and method for seismic protection of a structure is described. In one embodiment, the device has an anchor frame and a movement frame laterally translatable relative to the anchor frame. The anchor frame and movement frame have respective extension portions. A linkage is pivotably connected to the extension portion of the anchor frame. A compressed spring has a first end is attached to the extension portion of the movement frame and a second end attached to the linkage. The compressed spring has a spring force. In a rest state, the compressed spring does not apply a lateral force to the movement frame. In an engaged state, the compressed spring is configured to apply a lateral force to displace the movement frame in a lateral direction of a seismic load. The spring force is amplified by the linkage when the movement frame is laterally displaced to an amplification point.

An interlock for a vehicle platform lift meets the Federal Motor Vehicle Safety Standards (FMVSS 403) effective in late 2004 with minimum modification of vehicle electronic control arrangements. The interlock prevents forward and rearward mobility of vehicles unless the platform lift is stowed. The interlock operates to prevent accidental release but does not affect vehicle movement when the platform lift is stowed. Operation of the lift is allowed by placing the transmission in park or by placing the transmission in neutral and actuating the parking brake. A vehicle body computer controls operation when the vehicle is running. A bypass enable relay allows use when the vehicle's engine is not running.

A pod propulsion system comprises a housing defining a fluid duct and an annular drum rotatably mounted to the housing within the fluid duct. The annular drum has a drum interior and a cylindrical outer surface. The system further comprises a rotor mounted to the drum for rotation therewith, the rotor and the drum having a common axis of rotation. A bearing assembly mounted to the housing comprises a first bearing comprising a first plurality of bearing pads disposed circumferentially around the drum. Each pad has a pad bearing surface adapted to contact a first drum portion in a predetermined manner and is pivotably mounted to the housing so as to maintain contact of the pad bearing surface with the first drum portion in the predetermined manner when an orientation of the drum portion relative to the housing changes.

Systems and methods for website and application monitoring and testing inside from a private network are presented. An agent module resident on an agent device inside the secured network periodically sends an HTTP message to a controller server and receives an HTTP response. The agent module parses out a set of instructions from the content of the HTTP response and executes the instructions. The agent module collects and compiles responsive information resulting from the instructions being executed and sends the compiled information to the controller server for storage and reporting.
摘要:
A method and system for estimating a time shift required for symbol synchronization in a block oriented digital communication systems such as an orthogonal frequency division multiplexing (OFDM) or a discrete multi-tone (DMT) data transmission system. The method uses an N/d inverse discrete Fourier transform (IDFT), where N is a sample number and d is a decimation factor, or alternatively an N/(2d) inverse fast Fourier transform (IFFT) for a real received signal or an N/d IDFT for a complex received signal.
