Title: Helices, stabilisateurs d'helice, et vehicules a helice
Inventor: REHKEMPER JEFFREY
IPC: A63H27/133
Filed: 2002-11-06
Granted: 2004-08-10
Abstract: L'invention concerne des hélices, des stabilisateurs d'hélice, et des véhicules à hélice. Dans l'un des modes de réalisation de l'invention, on décrit un hélicoptère possédant un mécanisme moteur destiné à alimenter une hélice principale fixée à un axe d'entraînement qui s'étend vers l'extérieur à partir de l'hélicoptère. Cet hélicoptère comprend, en outre, un mécanisme de stabilisation fixé entre l'hélice principale et l'axe d'entraînement. Lorsque l'hélice principale est mise en rotation et commence à tanguer, la force centrifuge créée par la rotation de celle-ci va faire pivoter l'hélice principale autour du mécanisme de stabilisation, lequel dévie le tangage de manière que l'hélice principale reste en position sensiblement horizontale. En outre, diverses configurations d'hélice principale et des mécanismes de stabilisation qui offrent une stabilisation automatique peuvent être utilisées. Différents mécanismes moteurs peuvent être utilisés afin d'offrir d'autres façons d'alimenter et de mettre en rotation l'hélice principale.

Title: Method and apparatus using polarisation optical time domain reflectometry for security applications
Inventor: HARAN FRANCIS M
IPC: G08B3/10
Filed: 2004-06-21
Granted: 2012-09-25
Abstract: A preferred apparatus and method is presented in which a distributed fiber optic sensor is used in order to detect a disturbance along its length. A pulse of polarized light is launched into an optical fiber; as the pulse propagates along the optical fiber, it continuously loses a small portion of its energy due to Rayleigh backscatter. The Rayleigh backscattered light is analyzed using a polarization sensitive element such as a fiber polarizer. The dynamics of the time dependence of the polarization analyzed backscattered light is used to ascertain if there has been a disturbance along the length of the optical fiber. This technique can be used for applications in areas such as fiber optic telecommunications, perimeter security, fire detection, and pipelines.

Granted: 2010-05-18
Abstract: A correlation is derived between a variable, defined as "virtual age", indicative of brake fluid's service age and/or mileage and the concentration of metal particle(s) content in the brake fluid. Virtual age is utilized to estimate the degree of degradation of the brake fluid. A reactive test strip (10) is used to measure the concentration of metal ions such as either copper, iron or zinc in the brake fluid in terms of a readily visible color change to be observed by a test performer. The color chart (20) and a pre-set standard representative of the maximum concentration that is determined empirically to correspond to the desirable "virtual age" threshold for advantageous brake fluid replacement. An automated embodiment of the invention includes an optical instrument and determined whether a fluid replacement is recommended without reliance upon human perception or judgement.
