Title: System and method for sample detection based on low-frequency spectral components
Inventor: BUTTERS BENNETT M
IPC: G01N37/00
Filed: 2003-04-18
Granted: 2005-02-08
Abstract: Method and apparatus for detecting a selected material in a sample are disclosed. In the method, the sample (842) is placed adjacent a detector coil (846), for generating an electromagnetic time-domain signal composed of sample source radiation. The signal is first conditioned to convert the signal to an amplified conditioned signal from which frequency components above a selected frequency have been removed, then filtered to selectively pass low-frequency spectral components that are (i) in a frequency range between dc and 50KHz, and (ii) characteristic of the selected material. The filtered signal is cross-correlated with a data set of low-frequency spectral components that are (i) in a frequency range between dc and 50KHz, and (ii) characteristic of a selected material, to produce a frequency-domain spectrum in the frequency range within DC to 50KHz. This spectrum is then used to determine whether the frequency-domain spectrum contains one or more low-frequency signal components that are characteristic of the selected material, and diagnostic of the presence or absence of such material in the sample.

Abstract: Methods and apparatus for antialiasing images that contain one or more image objects such as colored text, line art, and graphical objects, such that the edge pixels of an antialiased image object will exhibit relatively uniform values, and the appearance of the image object is thereby improved. In one embodiment, an improved antialiasing filter is employed to detect at least one region within the received image. Upon detecting a region containing a background image level that adjoins an image object having pixel values in a range other than a range of limit values, the antialiasing filter sets the pixel values of the edge or border pixels of the image object to substantially the same value. Selection among a logical filter operation and an averaging filter operation may be adaptively employed in the antialiasing filter in order to obtain the desired uniformity of pixel values.

Abstract: A heated vent is provided which can be coupled to a pipe originating from a plumbing system within a building. A heating cable is wound around an inner cylinder which is wrapped in a conductive foil and enveloped by a larger diameter outer cylinder which is lined with a reflective foil defining a void there between. The cylinders are secured at an upper end by an end cap and at a lower end by a lower end cap and a tether is tautly secured within the inner cylinder by a bridge in an opening of the end cap and a lower disk engaged with the lower end of the inner cylinder to support ice blocks formed therein. The heating cable radiates heat, which is reflected by the reflective foil and absorbed by the conductive foil to prevent ice from forming on the inner surface of the inner cylinder.

Granted: 2012-05-01
Abstract: The present invention is concerned with cover assemblies for manually resetting pressure switches used on oil and gas pipelines. The cover assembly encloses a volume of space on the pressure switch that houses a reset switch which is activated by depressing a button located on top of the reset switch. The cover assembly has a housing with a rod or plunger extending through the housing. On the exterior end of the rod is a protective cap and on the interior is a flexible rubber hemispherical bumper. A spring disposed between the cap and the exterior side of the cover housing biases the bumper away from the button on the reset switch. In operation, the cap is pushed towards the housing causing the rod or plunger to advance towards and contact the reset switch button. The bumper deforms or balloons outward upon contact with the button so as to impart sufficient force to depress the button but not so much force so as to damage or break the reset switch itself. When the cap is released, the spring moves the bumper away from the reset switch allowing the bumper to return to its original shape.

Abstract: A method and apparatus of laser drilling a delivery port in a beneficial agent dispenser is disclosed. A dispenser has a compartment formed by a wall for containing a beneficial agent to be delivered. A laser beam is employed for burning at least partially through the wall. The laser beam and the dispenser are positioned relative to one another such that the laser beam is aimed at a predetermined port site on the dispenser. The laser beam is turned off (unenergized) during the positioning period. The laser beam is then energized and moved relative to the dispenser for scribing a delivery port proximate the port side. The scribing motion moves the laser beam from the port site along a course. Preferably the course is closed. The scribing motion causes the burning of the wall by the laser beam to scribe the delivery port. The positioning motion and the scribing motion are controlled by a scanning system. The laser source beam is energized during the scribing motion for burning the wall forming the delivery port therein for subsequent delivery of the beneficial agent therethrough.
