摘要:
A positioning system moves an object in two generally orthogonal directions using a rotationally adjustable bearing system that connects the object to two pairs of non-parallel rails, the bearing system permitting the object to be smoothly translated in one or two directions to a desired position in planar space. This translation is performed smoothly notwithstanding a lack of parallelism between the linear rails.

Methods, devices, and systems for selecting a link of a link group based on contents of a concealed header are disclosed. A network node operating method includes a first network node receiving a packet and concluding that a link group connecting the first network node to a second network node will forward the packet to the second network node. The method further includes determining that the packet includes a tunnel header and an original header concealed by the tunnel header, selecting one link from among a set of parallel links of the link group based at least on one or more fields of the concealed original header, and forwarding the packet to the second network node via the selected link.

A turbocharger compressor bypass valve is disclosed. In one example, the compressor bypass valve operates inversely proportional to engine throttle operation. The approach may simplify compressor bypass valve control and reduced engine system complexity.

An aircraft seat has an adjustable armrest in which the armrest platform is supported by a hinged attachment to an armrest support member. The hinged attachment between the armrest platform and the arm support member is located at the wrist-end of the arm support member near the aircraft control stick. The armrest platform and the armrest support are locked into position by means of telescoping struts that are controlled at the wrist-end of the arm platform member. The telescoping struts can be selectively locked to create triangular and/or quadrilateral trusses that lock the armrest firmly into position and may include springs or other elements to bias the armrest platform up and forward so that the armrest “floats” when the telescoping struts re released.

Embodiments pertain to simulator circuitry, particularly to simulator circuitry configured to simulate an electric vehicle and test an electric vehicle charger (110). A test unit (210) is configured to simulate a GFI current via modulator (1623) and to simulate electric vehicle loads via switched and combined resistor loads (1800). The test unit (220) provides for reprogramming of the electric vehicle charger (110) via a pilot line (323). The test unit (220) self-confirms its usability via associating received codes (1300).
摘要:
This invention includes methods and packet switches that translate a packet between a switching format and a transport format. One packet switch receives a packet intended for a destination port of a packet switch from a switching fabric of the packet switch and determines, based on the destination port, a treatment to be applied to the packet. The packet switch then applies the treatment to the packet prior to forwarding the packet to the destination port. The treatment may include adding a transport identifier to the packet.
摘要:
A centrifugal processing bag, system and method for separating the components of a mixed material is presented. The processing bag includes a hub and a first port for receiving the mixed material, where the first port includes an outlet positioned within the processing bag at a perimeter of the bag. The processing bag also including a second port having a second port inlet spaced proximate the hub and away from a central axis of the hub. The second port directs a separated material collected from the second port inlet out of the processing bag.
摘要:
Systems and methods for the automatic scoring of a vocal performance are provided. The systems and methods for providing feedback and scoring a vocal performance generally relate to receiving/processing a user's vocals, measuring the various performance qualities of the performance according stored evaluation policies and rendering a score according to stored scoring policies.

This document describes tools useful in relaying a data stream from a data device to a network tunnel, such as by enabling virtual switching using a provisional identifier to conceal a user identifier. These tools, for example, may use an inexpensive switch module to create virtual switch instances. To do so, the tools may assign data packets to a virtual switch instance by mapping the data packets to a particular provisional identifier and then modifying the data packets to include the provisional identifier. The switch module may then forward the data packets based on the provisional identifier rather than on the user identifier. The tools may remove the provisional identifier before forwarding the data packets to a destination.
摘要:
A pressure balance seal includes a sealing surface facing an inward radial direction, and a stator interface comprising at least one surface interfacing with a stator. The pressure balance seal further includes a friction reducing feature. The friction reducing feature includes a cavity on the sealing surface. The cavity is configured to receive a fluid such that a normal force acting on the pressure balance seal is counterbalanced by a force generated by a pressure of the fluid.
