A first pair of optical fibers are held and fixed to a supporting member in a cantilever form, and oppositely connected to a second pair of the optical fibers that are fixed to a square hole of the alignment material. A magnetic body is adhered to each of the first pair of optical fibers. Around the magnetic bodies, th...
Method and apparatus for reducing load distribution delay in an internet protocol switch. A system of messaging allows leader and follower cards within a switch to communicate without spanning the external network and without significant involvement by the central computing module within a switch. When a call setup req...
An improved structure of tact switch comprises a seat body, a first elastic element, a press set, and a closure body. After assembling and jointing the first elastic element and the press set in the seat body, the assembly procedure is to couple the closure body onto the seat body. When the press set is pressed down by...
A switch device adapted to respond to operation of steering handle comprises a disc which rotates in cooperation with operation of the steering handle and which has a plurality of actuating pieces which in turn actuate a rotor having a contactor which contacts with a contact member disposed in opposite relationship wit...
A time folded time space time (TST) switch with the establishing of a communication through path in one direction automatically establishing a path in the opposite direction in an adjacent time slot. With one transfer through a space switch made during an even time slot, the other transfer is made in a symmetrical fash...
An electric switch for a power tool, comprising: a slider slidably received in a switch casing along a longitudinal direction, a handle provided in the grip of the power tool for manually actuating the slider along the longitudinal direction; a plurality of fixed contact pieces arranged in an internal bottom surface of...
A switching circuit is provided to process a DC voltage and apply a low frequency AC voltage, having a trapezoidal waveform, to a co-axial cable transmitting the low frequency AC voltage to a load which may be powered by the low frequency AC voltage as well as a DC voltage. In one specific embodiment two of the switche...
A method and apparatus for processing a data packet of an Ethernet switch system in which packet information is transferred from a first device to a second device on the basis of field information of a packet inputted through an Ethernet, including the steps of: detecting a first address from a packet inputted to a pre...

A network switch having a shared memory architecture for storing data frames has a set of programmable thresholds that specify when flow control should be initiated on a selected network port. The network switch includes a queue for storing free frame pointers, each specifying available memory locations in an external ...
The present invention provides an RF switch, including a diode adapted to operate as a switch when a control current is applied thereto, a first CRLH transmission line of a Φ degree phase, which provides one signal transfer path from a terminal 1 to a terminal 2 when the diode is shorted due to application of a co...
A method and apparatus are provided for minimizing dense mode multicast flooding between a local area network (“LAN”) switch and a multicast capable router. The method includes the steps of detecting a prune message from the multicast capable router, identifying a multicast group from the prune message and setting ...
A method of providing a caller with a directory assistance dialog. The dialog is configurable, at any level of the dialog, from an automated speech recognition (ASR) dialog to an operator-assisted (OP) dialog. The dialog is handed off to an operator if any level of the speech recognition dialog fails. Also, a configura...
A cross-connect switch for fiber-optic communication networks employing a wavelength dispersive element, such as a grating, and a stack of regular (non-wavelength selective) cross bar switches using two-dimensional arrays of micromachined, electrically actuated, individually-tiltable, controlled deflection micromirrors...
