Abstract:
A ring binder mechanism has a housing and hinge plates supported for pivoting movement by the housing. The mechanism has rings, each including a first ring member mounted on a first hinge plate and a second ring member. The first ring member is movable relative to the second ring member between open and closed positions. The mechanism has a travel bar and a locking element that are free of fixed connection to the hinge plates and movable in translation relative to the housing and hinge plates. The travel bar blocks pivoting motion of the hinge plates when the ring members are closed. An elongate link connects a pivotable actuating lever to the travel bar such that pivoting motion of the actuating lever produces translational movement of the travel bar. The elongate link is oriented so it extends longitudinally relative to the housing.

Abstract:
An antenna device with a surface antenna pattern is formed either on an internal surface or on the external surface of a casing of an electronic device by film coating technology. The surface antenna pattern is either directly connected to a signal feeding line or connected to a signal feeding line through a signal guiding passage. In an embodiment, a recess is pre-formed on the external surface of the casing and then a surface antenna pattern is coated to the recess. The antenna device may further comprise an antenna coupling element arranged at the internal surface of the casing, in opposite to the surface antenna pattern. The antenna coupling element is inductively coupled with the surface antenna pattern for transceiving the signals to the electronic device.

Abstract:
In an apparatus and method for magnetic field assisted electrochemical discharge machining (ECDM), the magneto hydrodynamic (MHD) effect is utilized to improve the thickness of bubble film and the electrolyte circulation so as to enhance the machining accuracy and efficiency. Since charged ions in a magnetic field are induced by Lorenz force to move, and the electrolysis bubbles generated in the ECDM process are suffused with electrification ions on their surfaces, the electrolysis bubbles can be forced to move in the direction of the magnetic field without the need of mechanical disturbance. The present invention can be widely applied in the micro-machining of non-conductive brittle materials of different dimensions and shapes, comprising the forming of microchannels and microholes on a biochip, and in the micro-opto-electro-mechanical system (MOEMS) and various kinds of micro-machining fields. The machined surface is smooth and does not require a second time machining.
Abstract:
A ring binder mechanism includes an elongate housing and a ring support supported by the housing for movement relative to the housing. The ring support has an upper surface and a lower surface. A plurality of rings is provided for holding loose-leaf pages. Each ring includes a first ring member and a second ring member. The first ring member is mounted on the ring support for movement with the ring support relative to the housing between a closed position and an opened position. An actuator is mounted on the housing for pivotal movement relative to the housing for moving the rings from their closed position to their opened position. The actuator has a snap-lock connection with the housing.

Abstract:
A storage switch in accordance with an embodiment of the invention is a highly scalable switch that allows the creation of a SAN that is easy to deploy and that can be centrally managed. Moreover, such a storage switch also allows the deployment of a global infrastructure, allowing the resources of the SAN, such as storage devices, to essentially be positioned anywhere on the globe. Further, such a storage switch allows a multi-protocol SAN, e.g., one that includes both iSCSI or Fibre Channel, and processes data packets at “wire speed.” To further enable wire-speed processing, a switch in accordance with the invention has “intelligence” distributed to each of its linecards, through which it classifies packets into data and control packets, it performs virtualization functions, and it performs protocol translation functions. A switch in accordance with the invention further performs serverless storage services such as mirroring, snapshot, and replication.
