An RJ jack includes a first housing having bottom, side, rear, front and top walls defining an interior chamber and an opening through the front wall through which a plug may be received into the interior chamber. A plurality of contact fingers extend from beneath the bottom wall to and over the front wall and into the interior chamber. The spacing between the contact fingers in the interior chamber is equal to the spacing of corresponding contacts in the plug with the spacing of the contact fingers extending beneath the bottom wall being substantially greater. A second housing is removably secured to the rear wall of the first housing, the second housing containing a plurality of magnetic elements. At least two guides for receiving light emitting devices are formed on the rear wall of the second housing. The top wall extends over the first and second housings and has a stopper for limiting movement of the plug within the chamber and a locking mechanism for releasably securing the plug within the chamber, and is transparent for transmitting light from the light emitting devices.

An elongate polymer member having molecular helical orientation formed by rotation immediately after passing through the extrusion head. The elongate polymer member is rotated downstream of the extrusion head in the molten state prior to solidification in order to impart the molecular helical orientation. Rotating the polymer member in the molten state allows the helical orientation to be imparted at the molecular level, and allows for more rotations per lineal foot of extrusion.

A photonic switch may be formed using one of a selected group of non-linear optical materials. Each of the materials within this group has a refractive index that demonstrates a substantial peak as a function of wavelength. The photonic switch includes a positive gain, and thus acts as a photonic transistor. In addition, a photonic switch is formed so that a gate signal is applied in a direction that is substantially perpendicular to the direction of the input signal so that there is no effective contamination of the input signal by the gate signal affecting the output signal.

A photonic switch according to the present invention may be formed using one of a selected group of non-linear optical materials. Each of the materials within this group has a refractive index that demonstrates a substantial peak as a function of wavelength, where the peak occurs at a wavelength distinct from the wavelength of the input signal. A method of producing a photonic switch according to the present invention includes fabricating source and drain waveguides using micro-molding or micro-contact printing processes, or MIMIC (micro-molding in capillaries) of a UV-curable polymer. If desired, a gate waveguide may also be formed in part by these processes. The photonic switch also includes a photonic crystal formed from non-linear optical material, which may be formed, for example, using a block copolymer and nanoparticle composite in a MIMIC or μfluidics process. Such a process may employ a functionalized mold material to align the blocks.

In certain aspects of the invention, an extrusion apparatus for making a multilayer article includes multiple discs, each of which has at least one passageway configured to permit fluid flow therethrough in a flow direction. At least one of the discs includes a cone shaped portion extending substantially parallel to the flow direction.

An apparatus and a method for improving packet transmission and reducing latency in VoIP over WLAN using switched beam antennas having multiple directional antenna beams are disclosed. In an access point having a switched beam antenna, or other smart antenna system, the present invention extends the coverage area of an access point for authentication and association of a new WTRU, extends the access points coverage area during in session transmissions with a WTRU, and adjusts data rates. The method also controls Contention Period (CP)/Contention Free Period (CFP) timing amongst beams emanating from an access point having a switched beam antenna, or other smart antenna system. Fast diversity switching, frame level switching, lowered data rates, and scanning multiple directional antenna beams for the optimum transmission beam are disclosed to improve beam selection and packet transmission.
