Software for Analyzing Root Causes of Process Anomalies
Root Cause Analysis (RoCA) is a computer program that assists analysts in understanding the root causes of process anomalies. As used here, “process anomalies” includes incidents that have caused, or that can potentially cause, injuries to personnel, damage to facilities, abnormal costs,...
Briefs: Electronics & Computers
Active-pixel integrated-circuit image sensors that can be programmed in real-time to effect artificial reconfigurable vision on demand have been developed and demonstrated. In...

High-Performance Processor of Hyperspectral Images
The Remote Sensing Hyperspectral Engine (RSHE) is a special-purpose, portable computer that performs high-performance processing of hyperspectral image data collected by a remote-sensing optoelectronic apparatus. Typically, the remote-sensing apparatus is airborne or spaceborne, the images are of...
Briefs: Photonics/Optics
An optoelectronic system discussed herein measures the state of alignment (SOA) of an object under test in four of its six degrees of freedom (DOFs). This system was originally...

Software for Scheduling Use of Shared Resources
The Quick Utility for Intelligence Planning and Scheduling (QUIPS) computer program automates the scheduling of resources that must be shared among multiple tasks or groups. Designed to aid coordination of military intelligence operations at the division and brigade levels, QUIPS might also prove...
