A fluid dispense head is removably joined to a bottle, such as a wine bottle, or similar container, by having a hollow cylinder extend into the bottle and on one end sealed to a neck of the bottle with an annular gasket and on an opposite end joined to the dispense head. A nut on opposite end of the hollow cylinder limits entry of the cylinder into the bottle. When the nut is turned relative to the cylinder, the gasket seal is broken and the dispense head can be removed from the bottle. A set of annular gaskets of different diameters may be provided for bottles of different neck sizes.

Liquid dispensing head forcibly detachable from bottle or container

A liquid dispensing device including a dispense head configured to be placed and secured onto a bottle of liquid in a manner which enables the liquid to be dispensed. The dispense head includes a stopper having gas inlets and a liquid intake tube. A gas intake and a dispense spout are also mounted on the dispense head. A valve assembly allows pressurized gas to be introduced into the dispense head and into the bottle of liquid such that selective channeling of gas or liquid can be controlled to flow through the dispense spout thus enabling either liquid to pour through the spout or gas to clear the spout. A system utilizing this dispense head and a method of dispensing liquid using this head are possible with this device.

Method for liquid dispensing using a dispense head

One method of determining the signal to noise ratio of an optical signal models the noise floor based on amplified spontaneous emission (ASE) which is accumulated along the link. The ASE wavelength dependence is represented by a known mathematical function with a limited number of parameters. The parameters of this function are derived from measurements of the noise floor at a limited number of points by computational best fit means. A number of fiber grating filters at wavelengths between ITU allocated wavelengths are used to sample the optical noise and reflect the light back. An optical circulator is used to direct the reflected ASE light to an optical switch which allows the detector to select between transmitted and reflected light. The signal transmitted through the switch is monitored by a scanning filter with the appropriate resolution to resolve the signal or noise peaks. A first scan of the transmitted peaks is carried out and the signal is digitized and stored. A second scan of the reflected noise is carried out and digitized. A microcomputer computes the peak values and wavelengths, calibrates the wavelength scale from the known grating wavelengths, recomputes the ASE shape and the SNR, and communicates the results to outside agents when queried.

Method and apparatus for monitoring wavelength multiplexed optical

A bidirectionally amplifying rare earth doped fiber optical amplifier having an equalized gain at multiple wavelengths is disclosed for use in dense wavelength multiplexed bidirectional fiber transmission applications. In a first embodiment, a four port circulator is utilized with two amplifying fibers; one for each direction of propagation and a multiplicity of gratings configured to equalize the gain at the different wavelengths. Different embodiments utilizing three port and four port circulators are utilized. A more general amplifier device with equal gain at multiple wavelengths is disclosed.
