Abstract: A method and apparatus is described for the dynamic use of a property of a rendered indicator to impart information about a dynamic characteristic of an object, event or data structure through a visual, audible or tactile user interface. In the case of a visual indicator, a component of a video interface representing an object, event or data structure having a dynamic characteristic is assigned a visual property, for example a particular colour, which is varied as the dynamic characteristic changes. Thus, it becomes immediately apparent to a user in a user interface displaying a set of such components how the dynamic characteristic differs from one component relative to the others in the displayed set.

Abstract: There is an increase in the number of autonomous battery driven devices in the world today and also a growing need for rapid information of unwanted incidents. By combining the GMS- and GPS- technology with the invention and any sensor with the ability to generate a voltage due to external influences, one has reached an activation device perfect for alarm devices that can lay dormant for years with no mentionable power consumption until the day a certain incident occurs. This trait can be used in numerous applications where only the sensor type sets the limits. By using a piezoelectric gyroscope as sensor for instance, a potent tracking device is made, where motion generates a voltage, .which in turn will activate the entire device that will instantly start tracking the movement of the device and report this to its owner. This device will be of very small dimensions it can be attached to or hidden somewhere on personal belongings of a certain size; bags, suitcases, bicycles, paintings etc.

Title: Cyclonic liquid degassing separator and method for degassing a fluid mixture
Inventor: BETTING MARCO

Filed: 2007-06-27
Granted: 2014-07-22
Abstract: A method and cyclonic separator are disclosed for degassing a fluid mixture comprising a carrier liquid and gaseous and/or vaporizable components, wherein: the fluid mixture is accelerated in a throat section (6, 21) of a vortex tube (1, 20) such that the static pressure of the fluid mixture is decreased and vaporizable components evaporate into a gaseous phase and the fluid mixture flows as a substantially homogeneously dispersed gas-liquid mixture through the throat section; the accelerated fluid mixture is induced to swirl within a tubular mid section of the vortex tube such that the fluid mixture is separated by centrifugal forces into a degassed liquid fraction and a gas enriched fraction; the degassed liquid fraction is induced to flow into a annular liquid outlet conduit (4, 21); and the gas enriched fraction is induced to flow into a central gas outlet conduit(3, 24). An advantage of inducing the fluid mixture to flow as a substantially homogeneously dispersed gas-liquid mixture through the throat section is that the velocity of sound in such a mixture is low, thereby increasing the Mach number and the pressure reduction in the throat section and enhancing evaporation of gas bubbles in the mixture.
