20100017166 | VELOCITY DETECTOR - Apparatus for determining the velocity and direction of a moving object, the apparatus comprising: a coherent light (L) source arranged to generate an incident beam (B) of coherent light; an optical imaging system arranged to receive light reflected from a moving object passing through the incident beam and to focus the reflected light into a magnified image of the moving image; a first optical mask (M) through which the magnified image is projected, the mask having a first region of alternating opaque and non-opaque areas having a first spacing and second region of alternating opaque and non-opaque areas having a second spacing different from the first spacing; a first light detector (D) arranged to receive the light signal transmitted through the optical mask, the light signal comprising a series of pulses, and to calculate the velocity and direction of the moving object as a function of the pulse frequency and the spacing of the opaque areas of the optical mask. | 01-21-2010 |
20100045967 | VELOCITY DETECTOR - A method of detecting the velocity of a moving object comprising the steps of: passing a beam of coherent light through an optical mask having a pattern of alternating opaque and non-opaque regions formed thereon, whereby an image of alternating light and dark fringes is projected along the length of the light beam; causing the moving object to pass through the projected image such that a portion of the light beam is reflected from the moving object as a series of pulses; detecting the reflected light pulses and the frequency of the pulses; and calculating the velocity of the object as a function of the pulse frequency and the known separation of the fringes of the image. | 02-25-2010 |
20100063767 | Position Detector - Embodiments of the present invention provide a position detector for detecting the position of a helicopter blade comprising a sensor arranged to generate a signal in dependence on the position of a helicopter blade with respect to the sensor and a data processing module arranged to receive the signal from the sensor and generate an output indicative of the blade position from the received signal, the sensor comprising; a mask (M | 03-11-2010 |

20090217938 | Eyelash Extension System - An eyelash extension system having a backbone and a plurality of eyelash extensions attached to the backbone. An adhesive is applied to an application surface of the backbone, and the adhesive is selected from the group of adhesives comprising latex adhesives, solvent-borne adhesives, pressure-sensitive adhesives (PSAs), and hot melt adhesives. | 09-03-2009 |
20090217939 | Methods and Apparatuses For Applying Eyelash Extensions - An applicator for use with an eyelash extension system that has a backbone and a backbone surface. A plurality of eyelash extensions are attached to the backbone. The applicator has a closure having a closure surface facing the backbone surface, and a pair of clips, each clip including a first arm, a second arm, and a pivot attached to the first arm and the second arm. A first holder is attached to each of the first arms to releasably attach the backbone to the first arms. Further there is a second holder attached to each of the second arms to releasably attach the closure to the second arms. The first and second arms are moveable between a first state wherein the first and second arms are spaced relative to each other and a second state wherein the first and second arms abut each other. | 09-03-2009 |
20110290271 | Methods and Apparatuses For Applying Eyelash Extensions - An applicator for use with an eyelash extension system that has a backbone and a backbone surface configured to be joined with a closure surface. A plurality of eyelash extensions are attached to the backbone. The applicator includes a frame having a first end and a second end spaced laterally from the first end, a rail attached to the frame and extending laterally between the first and second ends, and a cam. The cam has a cam surface configured to contact the backbone of the eyelash extension system to urge the backbone to come into contact with the closure as the cam is moved laterally along the rail. | 12-01-2011 |
