摘要:
Micro-opto-mechanical chemical sensors and methods for simultaneously detecting and discriminating between a variety of vapor-phase analytes. One embodiment of the sensor is a photonic microharp chemical sensor with an array of closely spaced microbridges, each differing slightly in length and coated with a different sorbent polymer. The microbridges can be excited photothermally, and the microbridges can be optically interrogated using microcavity interferometry. Other actuation methods include piezoelectric, piezoresistive, electrothermal, and magnetic. Other read-out techniques include using a lever arm and other interferometric techniques.

The invention is directed to a portable carrying device that includes a housing, an elongated flexible strap extendable from the housing, and at least one rigid support arm attached to the housing and configured for supporting an article to be carried. The portable carrying device can include a coupler disposed on a first end of the elongated flexible strap and a mating structure disposed on a portion of the housing for releasably securing the coupler. The rigid support arm can be movable from a first position in which the rigid support arm is compactly stored relative to the housing, to a second position in which the rigid support arm is at least partially extended away from the housing. The housing can have at least one recess for receiving the rigid support arm and the rigid support arm can have a shape corresponding to the recess.

Optical viewing system for producing a simulated three dimensional image. The system includes electronic equipment for displaying an image on a first electronic display device. Additional electronic equipment is provided for displaying an image on at least one second display device. The at least one second electronic display device is a substantially transparent display device, whereby an observer can view through transparent areas of the second electronic display device. The first and second electronic display devices are located at different, predetermined locations along an optical viewing path such that the image displayed by the first electronic display device is projected through the second electronic display device. The first electronic display device includes an image projector and the second electronic display device includes a controllable pixel display spaced therefrom. The controllable pixel display is comprised of a positive pixel display panel having a field of pixel elements which are controllably illuminated. The controllable pixel display is substantially transparent such that the image produced by the controllable pixel display is overlaid upon the image produced by the image projector. A recording system including at least two image recorder channels is also disclosed for producing a plurality of images for simulating a three dimensional scene.

Systems and methods for creating data samples for data analysis. The method includes imaging at least a portion of a first object having a target portion to generate a first image, analyzing the first image by running a first series of algorithms using the first image to generate a first algorithm value cache, removing the target portion from the first object to form a modified first object, imaging at least a portion of the modified first object to generate a second image, analyzing the second image by running the first series of algorithms using the second image to generate a second algorithm value cache, generating a transformed result by running a subtraction process using the first algorithm value cache and the second algorithm value cache, and storing the transformed result in a knowledge base.
摘要:
A remediation method for decontamination of soil and groundwater that puts maximum remediation stress on the entire area and volume of contamination. This results in site restoration in days and weeks. The target contaminants are organic compounds such as hydrocarbon constituents associated with diesel fuel, gasoline, kerosene, solvents and creosote. Cleanup concentrations to non-detectable levels can be achieved when properly implemented. Positive pressure is used to push an uncontaminated gas throughout the entire contaminated area/volume. When contacting the contaminated area, volume and media, this gas becomes a carrier gas, stripping the contaminants and carrying them to ground level where they can be collected and treated or dissipated to the atmosphere. The method incorporates air entry points (vertical, horizontal, or directional) installed to a depth below the contamination, combined with a predetermined air entry point spacing (depth/spacing ratio). Use of an operating duty cycle enhances contaminant yield from the groundwater, the soil matrix below the groundwater table, and the soil above the groundwater table. Horizontal migration of contaminants during the process is prevented by the use of gas entry points around a boundary perimeter of the zone being purged. One or two days' use of the method produces the same results as one year of other remediation methods, such as "pump and treat". Transfer or removal rates of 40% to 50% per day of the existing contaminants are normal. No (vacuum) extraction wells are necessary to make this in-situ method work. Biodegradation is not a factor. Progress is measured by the amount of contaminants remaining. Site rehabilitation to regulatory standards, measured in micrograms per liter or parts per billion, can be achieved within weeks.

A system for imaging a substrate can comprise an image data source, an electromagnetic radiation source operatively connected to the image data source and configured to emit electromagnetic radiation in accordance with information provided by the image data source, and a DBR film applied to a substrate. The DBR film can comprise two types of film layers, wherein the two types of film layers are each stable at ambient temperature, each of the two types of film layers having a glass transition temperature (TG) that is lower than the temperature needed to produce deformation of bulk material of the two types of film layers upon interaction with the electromagnetic radiation.
