Abstract: A device for measuring dew point or humidity comprises a single resonator and at least one temperature-regulating element arranged to control the temperature of the resonator by heating and/or cooling. Frequency measuring circuitry is arranged to generate signals indicative of measured frequencies of the resonator. At least one controller or processor receives the signals and determines the temperature of the resonator at which condensation (e.g., dew, frost, or condensed vapor) appears on the resonator or evaporates from the resonator according to the signals.

Abstract: A computer-based multi-media management system for controlling access to stored multi-media assets utilizing a database, which contains media objects which include video images, still images and text; and a server for enabling the stored assets to be accessed by a user via a communications network, and a taxonomy system allowing a user to access the stored assets, the taxonomy system linking categories of media objects in the database in a hierarchical tree system with each node representing a category, and wherein the management system has, for a selected plurality of media objects as represented by the categories, association links linking categories so that a user can traverse the tree by moving from a first category to a second category which need neither be at the same hierarchical level in the tree or have any form of parent/sibling relationship with the first category.
