Abstract: A set of user interface tools is described facilitating asynchronous adjudication of one or more regions-of-interest in a medical image by a group of two or more graders, each of which has access to the set of tools in a workstation environment. The set of tools include (1) a feature for enabling the graders to assess the medical image and manually delineate one or more specific regions-of-interest (ROI) in the medical image, (2) a feature for assessing the ROI(s) delineated by other graders, including display of the ROI delineated by other graders; (3) dialog features for explaining and discussing the assessments, including a text feature for discussing the assessments. The dialog features and the ROIs delineated by all the graders are visible to all the graders on the workstation display as they collectively adjudicate the medical image in a round-robin manner. The set of tools further include (4) a feature for manually verifying grader agreement with the other graders' assessments.

Abstract: A system for detecting and graphically displaying a contents of a fast-moving target object comprises: a radiation source, having a position such that at least a portion of radiation emitted from the radiation source passes through the fast-moving target object, the fast-moving target object having a variable velocity and acceleration while maintaining a substantially constant distance from the radiation source and being selected from the group consisting of: a vehicle, a cargo container and a railroad car; a velocity measuring device configured to measure the variable velocity of the fast-moving target object; a detector array comprising a plurality of photon detectors, having a position such that at least some of the at least a portion of the radiation passing through the target object is received thereby, the detector array having a variable count time according to the variable velocity and a grid unit size; a counter circuit coupled to the detector array for discretely counting a number of photons enterin

Abstract: A universal power manger capable of power converting a universal range of unregulated power inputs into a high-resolution programmable regulated (constant) output voltage or a high-resolution programmable (constant) current and of charging and/or diagnosing standard battery chemistries with a universal range of unregulated AC and DC power inputs. It includes an extremely high resolution monolithic potentiometer of at least 512 positions. Preferably, two or more extremely high resolution monolithic potentiometers are used to create a high resolution resistance chain, each having at least 512 positions and at least one tap point set according to a user selected output voltage and/or current. Each potentiometer has a resultant tap point selected by an analog switch in accordance with a user selected output that determines overall resistance in the resistance chain, the output voltage being proportional to the overall resistance.
