  • Publication number: 20100014067
    Abstract: The present disclosure provides method and apparatus for detection of airborne particulates. Liquid droplets comprising reagents capable of reacting with particulates whereby to produce emitted light are introduced to an air flow comprising particulates, whereupon the particulates and liquid droplets agglomerate thereby producing the emitted light. The light is detected by a suitable detector (7), and agglomeration may be enhanced by application of an oscillating electric field (6). The disclosure is particularly concerned with detection of biological particulates.

  • Publication number: 20080219772
    Abstract: A berm system for retaining water in flood areas and erosion prevention means against wind and wave action and the like. The berm system basically is obtained of high density polyethylene defining a front side portion, a rear side portion and a top; at least a part of said top of the berm adapted for traction; and a means for holding the berm in place at the center and lap joints. The berm system is adapted for use in conjunction with existing or built earth/sand berms or can also be used on its own without any further earth/sand berm for barrier against flood, or erosion resulting from wind and/or wave action. The berm system is simple and cost effective and can be installed very fast in various flood areas as well as regions requiring erosion control.

  • Publication number: 20080002935
    Abstract: Disclosed is a method of forming an optical monitoring or transmitting light guide and a resulting apparatus that begins by bonding a bundle of optical fibers together using an epoxy and polishing the distal end of the bundle of optical fibers to create an optical aperture. The ratio of fiber size to binder particulate size of the epoxy used in the bonding process is sufficient to maintain the integrity of the bundle of optical fibers during the polishing of the distal end. The method positions the bundle of optical fibers into a protective sheath and a connector. The coefficient of thermal expansion of the epoxy used in the bonding process matches that of the connector. Once assembled, the invention positions the connector through the opening in the surface of a device, such that the distal end of the bundle of optical fibers is either recessed in, substantially flush with, or extends from the surface of the device through which the connector extends, depending on field-of-view requirements.

  • Publication number: 20070053293
    Abstract: Optimizing data rates for video services on a broadband network. Different data rates can be delivered to a subscriber premises depending on the size of the display screen connected to a set-top box, the type of content being requested, or whether there is real-time viewing. Therefore, the data rate can be optimized to maximize the number of video streams that can be delivered to any one subscriber without causing a perceived reduction in video picture quality.

  • Publication number: 20070025517
    Abstract: An x-ray tube (24) includes an anode (42) defining a target. A cathode assembly (40) is in operative relationship with the anode to produce x-rays (56). An evacuated envelope (35) encloses the anode and cathode. The evacuated envelope includes a metal frame portion (39). The material comprising the metal frame portion has a backscatter coefficient. An x-ray transmissive window (41) is joined in a vacuum tight manner to the metal frame portion of the evacuated envelope. The material comprising the x-ray transmissive window has a backscatter coefficient. A backscatter layer (90) is deposited on the x-ray transmissive window and the metal frame portion of the evacuated envelope around the x-ray transmissive window. The backscatter layer has a backscatter coefficient greater than the backscatter coefficient of both of the window and the metal frame.

  • Publication number: 20050285090
    Abstract: A stabilizing jack (10) for securement to the underside of a recreational vehicle. The jack includes a channel frame (25) formed with longitudinal trunnion flanges. A longitudinal screw (50) is rotatably mounted in the channel and drives a trunnion (38) that rides between the trunnion flanges (22a, 22b). A support leg (30) is rotatably connected to the trunnion. Rotation of the screw drives the trunnion towards an outboard end of the jack and lowers the support leg to its supporting position.
