Granted: 2006-04-25
Abstract: The alarm system is capable of detecting both conductive and non conductive liquid level increases, designed for indoor operation, and ideally suited for detecting basement flooding or leaky domestic steel oil tanks or other fluid containment devices. A float, positioned above any surface such as a contained area (sump or drip pan), rises with the presence of a liquid, allowing a spring loaded switch to rise, triggering a 9- volt powered battery electric circuit. The electric circuit, enclosed in a plastic enclosure, activates an audible pulsating alarm when triggered. A battery voltage monitor incorporated in the electric circuit, tests the battery voltage on a continuous bases, and will trigger the unit into the alarm mode when the battery voltage is insufficient to sustain continuous operation. A simple convenient self check feature allows the user to simply check the unit, at anytime. An external connection is provided to allow the unit to be connected to a home security system or other external device to allow extended protection or secondary operations.

Title: Attenuation du chatoiement pour une detection coherente au moyen d'un signal a large bande
Inventor: HASSON VICTOR H
IPC: G01S13/10
Filed: 1999-07-19
Granted: 2007-03-13
Abstract: Pour effectuer simultanément plusieurs mesures indépendantes du spectre de la lumière réfléchie par une cible, on éclaire cette cible avec un train d'impulsions laser produisant un spectre de raies dans le signal d'éclairage. On établit une dimension caractéristique de l'ouverture de réception sur la base d'une longueur d'onde d'éclairage, d'une dimension de la coupe transversale de la région éclairée d'une cible et de l'écart séparant une cible et l'ouverture de réception ou le plan de l'image. La dimension caractéristique est constituée par l'espacement des crêtes d'un diagramme de chatoiement d'un plan d'image. Le chatoiement est produit par une interférence destructive et constructive d'ondes de lumière cohérente réfléchies par la cible. L'utilisation de plusieurs télescopes de réception présentant ladite dimension caractéristique permet d'obtenir des mesures indépendantes réalisées simultanément par chaque télescope de réception. En outre, pour produire un train d'impulsions de rayonnement d'éclairage ou de lumière, on utilise le laser en modes bloqués afin de synchroniser les composants sinusoïdaux à des fréquences de raies spectrales du train d'impulsions, l'espacement des raies spectrales étant au moins une fréquence de décorrélation. Le nombre de raies spectrales émises dans chaque impulsion est égal au nombre de mesures indépendantes réalisables simultanément lors de la réception du train d'impulsions réfléchi de lumière. Dans une variante, au lieu de la raie spectrale, la fréquence peut être balayée linéairement pendant la durée de l'impulsion, de sorte que la largeur de bande générale de la fréquence est égale à la largeur de bande englobée par le spectre de raies d'une impulsion.

Title: Fluid dispenser with child-resistant nozzle assembly
Inventor: GOOD ROBERT J
IPC: B05B7/00
Filed: 2001-05-03
Granted: 2006-07-18
Abstract: A dispenser body supports a nozzle cap for rotation about a longitudinal axis thereof between ON and OFF positions. A nozzle cover surrounds the nozzle cap, is freely rotatable about the nozzle cap and is movable along the longitudinal axis relative to the nozzle cap, to render the same child resistant. Engaging portion on the nozzle cap and the nozzle cover are longitudinally spaced apart in a first longitudinal position to prevent rotation of the nozzle cap by rotating the nozzle cover, thereby preventing the nozzle cap from being rotated from one position to another. In a second longitudinal position of the nozzle cover relative to the nozzle cap, the engaging portions interengage to enable the nozzle cap to be rotated by the nozzle cover to enable the nozzle cap to be rotated from one position to another.

Abstract: A device, system, and method provides for lung size reduction by permanently collapsing at least a portion of a lung.  The lung portion may be collapsed by obstructing the air passageway which communicates the lung portion to be collapsed. The air passageway may be obstructed by an obstructing member which precludes airflow in either direction or with a one-way valve which permits air to be exhaled from the lung portion while precluding air from being inhaled into the lung portion. In addition, a vacuum may be pulled within the lung portion to be collapsed for collapsing the lung portion and while the lung portion is collapsed the obstructing member may be placed in the air passageway to maintain the lung portion in a permanently collapsed state.
