Abstract: Methods and apparatus for a radiation monitor. In one embodiment, a radiator monitor comprises a housing, a detector material having an adjustable density in the housing, an optical coupler adjacent the detector material to receive Cherenkov energy generated in the detector material, a photodetector coupled to the optical coupler, and a processing module coupled to the photodetector to determine whether a detection threshold is exceeded.

Abstract: Project property sheets store project compiler and tool properties that are shared across multiple software projects. Property sheets enable a global repository of compiler and tool settings, so that changes in a global project property sheet will automatically propagate to the project property sheets that inherit from the global project property sheet, or from other project property sheets that inherit from the global project property sheet. Users of project property sheets are able to customize their project property sheet by defining their own compiler and tool properties. Defined compiler and tool properties override or supplement compiler and tool properties found in the global project property sheet.

Abstract: An apparatus and method for tracking an object includes a transmitter that generates a signal and a receiver that receives the signal generated by the transmitter. The receiver generates an alert signal when a distance between the transmitter and receiver is greater than a predetermined value. The receiver is retained in a retaining element, such as a wrist band, while the transmitter is secured to an object. The receiver is programmable to generate the alert signal only when the predetermined distance has been exceeded. The retaining element optionally includes multiple retaining features so that multiple receivers may be retained in a single retaining element. Each receiver is programmable to communicate only with one corresponding transmitter by assigning each transmitter/receiver pair with a unique identification code. The unique identification code expires after use so that each transmitter may only communicate with a single receiver.

Abstract: An extensible project system for software development is provided by allowing a flavor, with a specific purpose, to be applied to a base project system. More than one flavor may be applied. Where components are distributed objects, such as where COM (component object model) is used, the project system is assembled by aggregation of a base project object, which contains some data for creating a project system with a flavor object, which modifies the project system. The base project object is the participating object in the aggregation and the flavor object is the controlling object. Multiple flavors may be applied to create a project system intended for multiple purposes, corresponding to the applied flavors.

Abstract: A portal trace detection apparatus is provided for detecting minute particles of interest, such as traces of narcotics, explosives and other contraband. The apparatus includes a portal through which a human suspect will pass. A detection apparatus is disposed at least partly in the ceiling of the portal, and hence above the human subject in the portal. Particles of interest will be entrained in the human thermal plume that exists in the boundary adjacent the suspect, and will flow upwardly from the suspect to the detection apparatus in the ceiling of the portal. The ceiling is coated with an anti-static material so that particles are more likely to flow towards the detector and less likely to be affixed electrostatically to the ceiling.

Abstract: Sample traps or wipes are provided for a detection system for detecting contraband materials. The sample trap is formed from an open weave glass fabric coated with a thin layer of Teflon and roughened to cut through the surface of Teflon and to break some of the glass fibers. Alternatively, the sample trap is non-woven felt fabric made of high temperature polyamide fiber. The sample traps are used in a detector, such as an ion trap mobility spectrometer. The detector includes a desorber which feeds dry air from a manifold above and below the sample trap through a series of holes along the mouth of the desorber. The dry air passes through the trap and purges out unwanted atmospheric constituents that could otherwise affect the performance of the detector. The purged air passes to the outside atmosphere, thus creating a dry curtain at the entry to the desorber.

Abstract: An extension attachment for wrenches for allowing the user to reach hard-to-reach areas of an object to either tighten or loosen screws or nuts therefrom. The extension attachment for wrenches includes an elongate support member having a handle member and a wrench support member attached to the handle member and having a first end, a second end, a first planar side and a second planar side with the elongate support member also including flange members extending along either edge of the first planar side and being spaced apart to receive and retain a portion of a wrench therebetween; and also includes a fastening assembly for fastening a wrench to the wrench support member.
