Abstract: A closure for the neck of a container such as a water bottle includes a cap 32 for engagement with the neck, and a valve plug 44. The cap has an inner guide sleeve 38 which sealingly receives the valve plug 44, which is provided with latches 50. When the bottle is placed on a liquid dispensing station such as a water cooler a probe 5 sealably enters the sleeve 38 and an actuator head 70 engages the latches 50 to carry the plug out of the sleeve 38. The probe requires minimum insertion force. One or more water flow ports 72 are provided in the probe 5 to conduct water out of the bottle, while air may enter the bottle via a vent port 73 and vent apertures in the valve plug 44. This allows simultaneous exchange of air and water without risk of air entrainment whilst providing a short penetration distance.

Abstract: A system that facilitates blind source separation in a distributed microphone meeting environment for improved teleconferencing. Input sensor (e.g., microphone) signals are transformed to the frequency-domain and independent component analysis is applied to compute estimates of frequency-domain processing matrices. Modified permutations of the processing matrices are obtained based upon a maximum magnitude based de-permutation scheme. Estimates of the plurality of source signals are provided based upon the modified frequency-domain processing matrices and input sensor signals. Optionally, segments during which the set of active sources is a subset of the set of all sources can be exploited to compute more accurate estimates of frequency-domain mixing matrices. Source activity detection can be applied to determine which speaker(s), if any, are active.

Abstract: Cigarette filter rods having individual objects positioned at predetermined intervals therein are prepared by transferring the individual objects from a rotating horizontal pan to a rotating vertical wheel and then depositing the object into a web of filter tow. Each object is positioned within the moving web of tow. The web filter material and the objects positioned within the web are introduced into a rod-forming unit wherein the rod is formed. The rate of feed of the filter tow, the rate of rotation of the horizontal pan and the vertical wheel are controlled relative to one another such that objects are positioned at predetermined intervals along the rod. Cigarette filter elements having well controlled amounts of flavorant contained therein can be made from the rods.
