20090169051	SYSTEM AND METHOD FOR DETECTING ITEMS OF INTEREST THROUGH MASS ESTIMATION - A system and method for identifying an object based on its estimated mass. In one aspect, a method for estimating a mass of an object is provided. The method includes acquiring image data including a plurality of image elements, calculating a histogram based on the image data, calculating a computed tomography (CT) number of the object using an anisotropic erosion operator, and determining a perimeter of the object. The method also includes calculating an estimated mass of the object using the CT number and a first subset of image elements of the plurality of image elements, the first subset of image elements defined by the perimeter of the object, and outputting at least one of the estimated mass of the object and an image including the object.	07-02-2009
20090166531	APPARATUS AND METHOD FOR GENERATING AN AMMONIA GAS - Apparatus and method for generating ammonia gas. In one aspect, a method for generating ammonia gas for use in an ion mobility spectrometry (IMS) system is provided. The method includes inserting a device into a space defined within the IMS system, the device including an ammonia compound. The method also includes activating to decompose and to produce the ammonia gas without producing water vapor. The method also includes emitting the ammonia gas into the IMS system.	07-02-2009
