Abstract:
The invention relates to a method and apparatus for topological or shape measurement of objects of any size, by using an interferometric technique comprising an optical source, with selectable coherence, allowing contouring from single shot interferograms or holograms, giving access to absolute tri-dimensional topography of illuminated object. A contour depth is obtained based on only one acquisition, which enables to obtain depth signal and quantitative measurements even in harsh environments and on changing samples. This allows for real time record of topography changes and/or distance to surface measurements. The apparatus can be used independently for high precision metrology or incorporated in or connected to any imaging device like an endoscope. This opens new possibilities for industrial metrology as well as for medical applications.
Abstract:
A rectangular ceiling tile proportioned for use in a standard rectangular ceiling grid module formed by grid tees, the tile having a pair of conductors arranged to feed low voltage electrical power from the grid elements to an electric or electronic device carried on the tile, the conductors each extending to an edge or edges of the tile and adapted to make physical contact with a conductor carried on a grid element when supported on such grid element.
Abstract:
An elongated grid tee for supplying low voltage power on a suspended ceiling comprising at least two electrically conductive paths electrically insulated from each other, extending lengthwise of the tee, and accessible for receiving or supplying electrical power at numerous locations along the length of the tee.
Abstract:
An electrically conductive element, including an insulator and a first conductor, is provided, which can be affixed to a second conductor consisting of conductive structural element, wherein the insulator is positioned between the first and second conductors to electrically isolate them. A power supply may be connected between the first and second conductors to provide power thereto, and an electrical device may be connected across the first and second conductors.
Abstract:
A suspended ceiling elongate grid tee having a lower flange, a vertical web, and an upper hollow reinforcing bulb, at least some of the flange, web and bulb elements, having relatively flat exposed or accessible surfaces, and a plurality of pairs of conductors attached to said flat surfaces and extending along substantially the full length of the tee whereby grid tee is capable of carrying at least two fully independent DC circuits.

Abstract:
An electrically conductive module is provided. The module includes a panel configured to engage with one or more conductive structural elements. The module further includes conductive layers formed on or in the panel. Each conductive layer has a terminal configured to be in electrical communication with at least one of the conductive structural elements. In one embodiment of the present invention, a first terminal is configured to be in electrical communication with a first conductive structural element and a second terminal is configured to be in electrical communication with a second conductive structural element. In another embodiment of the present invention, both a first terminal and a second terminal are configured to be in electrical communication with a first conductive structural element. In this embodiment, the first and second terminals are respectively configured to be in electrical communication with first and second conductive portions of the first conductive structural element.

Abstract:
A glass retrofitting system with an adaptor is configured to mount a glass member to a wall or window frame. The glass member may be an upgraded insulated glass unit to replace an existing glass in a wall or window frame. The adaptor may include a mating portion (or an anchor member) which fits into an existing glazing pocket of the existing window or wall frame. The width of the existing glazing pocket may not be wide enough to accommodate the upgraded insulated glass unit. Thus, the adaptor may form a new glazing pocket suitable to hold the upgraded insulated glass unit, and the insulated glass unit may be mounted or installed into the new glazing pocket formed by the adaptor. The adaptor may be formed of low thermal conductivity material, or of a single piece or a plurality of pieces.
