Abstract:

Disclosed is a method of automatically sensing and controlling beverage quality for soft drinks from a fountain dispenser, for example, comprising the steps of supplying a first fluid, such as water or carbonated water, wherein the flow of the first fluid is controlled by a first valve, supplying a second fluid, mixing the first fluid and the second fluid, passing a sample of the mixture of the first fluid and the second fluid onto a sensing surface of a fixed optic sensor, measuring one or more properties of the sample, such as, for example, refractive index, temperature, and pressure, controlling the first valve based on the one or more properties, and dispensing the mixture. The first valve may be proportionally enlarged and reduced or it may selectively opened and closed pursuant to a desired duty cycle. The present invention further comprises a system for automatically sensing and controlling beverage quality, comprising a controller means, a first valve electrically coupled to the controller means for controlling supply of a first fluid, a second valve electrically coupled to the controller means for controlling supply of a second fluid, and a fixed optic sensor electrically coupled to the controller means.

Abstract:

The present invention provides an apparatus and method of selecting a unique combination of materials and dimensions for fabrication of a micro-electromechanical switch for improved RF switch performance. An electrode material is selected which exhibits a resistivity resulting in improved insertion loss for a predetermined switching speed, a dielectric material is selected which exhibits a permittivity resulting in improved isolation, and an airgap thickness is selected resulting in a pull-down voltage approximately equal to a supply voltage of the micro-electromechanical switch in which the isolation and predetermined switching speed are also functions of the airgap thickness.

International Classification:

H01G 212

US Classification:

361 15, 361123, 200181

Abstract:

The present invention includes an integrated circuit switch including a membrane supported over a first conductor on a substrate, a conductive region on the membrane and connecting to the first conductor on the substrate, a pulldown electrode on the substrate and under the membrane and a pillar to support the membrane after the pulldown threshold has been reached. A voltage greater than a pulldown threshold is applied between the membrane and the pulldown electrode will pull the membrane down to make a capacitive coupling to the first conductor. The addition of the pillars increases the upward restoring force when the activation voltage is removed.

International Classification:

H04B 1010

US Classification:

398129, 398201

Abstract:

A method for controlling an optical, path-to-sight link, the optical link including a source of light having a beam of light, a controllable beam steering device and an actuator to permit steering the light beam, the beam steering device being controllable by predetermined control signals. The method includes the following steps. The beam steering device is controlled so as to scan the beam of light in a first predetermined pattern. First direction is received data from a remote receiver including a light detector, the direction data corresponding to a direction of the beam at which the scanned beam of light is detected by the light detector. Responsive to the first direction data, a first beam direction is determined for data communication from the link to the receiver. The beam steering device is controlled to maintain a communications beam direction corresponding to the first beam direction. The beam of light is modulated with electronic signals.

Abstract:

A packaged micromirror assembly ( â) is disclosed. The assembly ( â) includes a mirror element ( ) having a mirror surface ( ) that can rotate in two axes. Magnets ( ) are attached to the mirror element ( ), to permit rotation of the mirror surface ( ) responsive to the energizing of coil drivers ( ). A sensor ( ) is disposed under the mirror surface ( ) to detect mirror orientation. In one aspect of the invention, the sensor ( ) includes a light source such as an LED ( ) that imparts light through an aperture ( ) at the underside of the mirror surface ( ). Light detectors ( ) are arranged at varying angles, and detect relative intensity of light reflected from the underside of the mirror surface ( ), from which the rotational position of the mirror ( ) can be derived. According to another aspect of the invention, a conical sensor ( ) with multiple insulated segmented capacitor plates are arranged under the mirror surface ( ). Variations in the capacitance between the mirror ( ) and the various segments of the sensor ( ) indicate the position of the mirror ( ).
