摘要:
The present invention relates in general to cartridges for storage and processing of pre-formulated food materials, and methods and apparatus for processing the food materials stored within such cartridges. More particularly, the present invention relates to a unique, fully recyclable food cartridge, comprising an annular cylindrical container within which the pre-formulated food material is sealed for storage and cooking, an integral burst disk, a discharge die located above the burst disk and a sensory device with information for controlling the thermo-mechanical processing of the food materials stored within such food storage cartridge by the method and apparatus. The method includes the steps of inserting the cartridge into the apparatus, causing the apparatus to heat and pressurize the annular container until the burst disk ruptures and collapsing the cartridge into a thin, recyclable disk by means of application of controlled pressure on the lower annulus of the container to assist in the ejection of the cooked food through the discharge die.

The invention relates to a method for the estimation of chromatic dispersion in multichannel optical network spans during active operation. The invention further discloses a chromatic dispersion monitor for real time monitoring of accumulated dispersion in individual channels. The method effectively estimates accumulated chromatic dispersion by obtaining a contour map of the eye diagram correlating more than three points for measuring at least two parameters to known dispersion. This can provide accurate BER indication before failure occurs and provide indication of the sign of dispersion for faster correction. A chromatic dispersion monitor includes a high speed linear receiver to receive individual channel signals from a tunable filter, a clock recovery circuit with a variable time delay device for obtaining points to establish the contoured eye map and a processor for calculating metric values from the contoured eye map and correlating the calculated metric vales to a stored library of accumulated chromatic dispersion.
