A medical laser apparatus comprises: a solid laser oscillating source which emits a beam of a wavelength .lamda.1 in an infrared region of approx. 1040 nm to approx. 1080 nm; a first fiber-based Raman shifter including a first Raman fiber which generates, when receives the .lamda.1-beam from the laser oscillating source, a first-order Stokes beam of a wavelength .lamda.2 different from the wavelength .lamda.1 by stimulated Raman scattering, the first Raman fiber being formed with a pair of fiber...

A method of making a gaseous fluid data sensor assembly for acquiring data regarding the ambient environment adjacent a surface of an airframe with adjacent air speeds below 40 knots (or another aerodynamic structure with low speed gaseous fluid flow adjacent thereto) having a flexible substrate adhesively conforming to the airframe surface, a conformable cover layer and a relatively thin air data sensor for sensing air pressure between the substrate and the cover layer. The method includes form...

A parquet board with a groove and tongue edge profile comprising a projecting tongue (14) on at least one edge of each parquet board (10,12) and a receding groove (16) on at least one opposite edge of the parquet board. The top edge of the tongue (14) is provided with a projecting locking lip (24) running in the longitudinal direction of the tongue, and there is a corresponding locking recess (26) running in the longitudinal direction of the groove in the bottom edge of the groove-boundary-formi...

The present invention relates to a burner, substantially comprising a swirl generator for a combustion air stream and means for introducing fuel into the combustion air stream, the swirl generator having combustion-air inlet openings for the combustion air stream that enters the burner, and the means for introducing fuel into the combustion air stream comprising one or more first fuel feeds having a group of first fuel outlet openings, arranged distributed around the burner axis at a combustion ...

A method for the utilization of a woven or loop-formingly knitted fabric which acquires an electrostatic charge as a result of a specific treatment for filtering airborne, dusty allergens such as pollen in a pollen guard mountable in front of windows and doors over the whole area thereof.

Novel methods and apparatuses are disclosed for the treatment of wastewater to reduce often associated offensive odors by promoting aerobic conditions through decreasing the amount of oxygen required to maintain aerobic cultures and/or aerobic biological activity in the wastewater. Also, the wastewater is screened or otherwise separated the wastewater to remove or concentrate the solids which are anaerobically digested. By concentrating the solids, a smaller digester can be used. The anaerobic d...

A display device has first row select lines for selecting rows of picture elements, picture element signal lines for supplying picture element signals to picture elements which are selected, a drive unit having drive circuits arrayed at respective picture elements each for driving the corresponding actuator in response to a picture element signal, and a selector unit for selecting the actuators corresponding to selected picture elements. Each of the drive circuits has a drives potential generati...

A method and apparatus to illuminate a target. The apparatus can comprise a first lens configured to receive light from the light source, a diffractive optical element configured to receive the light from the first lens and to regulate the light into regulated light, and second lens configured to receive the regulated light and to direct the regulated light onto a selected area of the target.

A method and apparatus for recovering a second transport stream included within a first transport stream and reducing timing anomaly imparted to the second transport stream within the context of a front-end device subject to random access via a data bus, illustratively a PCI bus. A first transport stream is received from a transport medium, the first transport stream having disposed therein packets associated with a second transport stream. The first medium tending to impart jitter to the first ...

An electronic component placement machine and an electronic component placement method are disclosed. A takeout and transfer head, provided on rotary chip takeout and transfer mechanism, removes a chip from a feeder and flips it. A placement head receives the flipped chip and places it onto a board. An image of the chip at a pre-centering recognition position is captured during a takeout and transfer operation, during which the takeout and transfer head transfers the chip to the placement head a...
