Network Camera

Axis Communications, Chelmsford, MA, offers the AXIS P3301 network camera with multiple H.264 streams. The fixed-dome camera uses the company’s ARTPEC-3 chip and is designed for unobtrusive video surveillance in exposed indoor environments. It features progressive scan and a wide dynamic range, providing images of both illuminated and low-light areas. Multiple H.264 streams and Motion JPEG streams can be provided simultaneously in full frame rate, or individually optimized for different quality needs and bandwidth restrictions.

Widescreen Operator Panel

Beijer Electronics, Schaumburg, IL, has released the H-T70t operator panel, part of the H-series that offers fundamental HMI functionality for machines and processes. The H-series includes keypad and touchscreen panels with displays ranging from 3.0 to 10.4". The H-T70t widescreen panel offers 800 × 480-pixel resolution on a 7" display. The TFT-display ensures the information is presented with clarity and a high level of detail. The panel is available in two versions, one with a built-in Ethernet port. Both models have a touchscreen interface, a menu key, and six user-defined function keys. USB-support is provided with two host ports and one device port.

Large-Format MWIR Lens

StingRay Optics, Keene, NH, offers a 50-mm midwave infrared (MWIR) large-format lens assembly with an optional microscanning and step-stare sensor capability. The lens can be a standalone solution for large-format detectors or used in conjunction with enhanced-resolution features. The lens is used with cooled cameras with focal planes up to 28 mm diagonal. The speed of the lens is based on an F/2.3 cold shield arrangement, and the 50-mm focal length is derived from the required 1-meter sampling area at an operating distance of 2.5 km. The lens provides diffraction-limited performance over the entire field of view.

Quantum-Inspired Maximizer

A report discusses an algorithm for a new kind of dynamics based on a quantum-classical hybrid-quantum-inspired maximizer. The model is represented by a modified Madelung equation in which the quantum potential is replaced by different, specially chosen “computational” potential. As a result, the dynamics attains both quantum and classical properties: it preserves superposition and entanglement of random solutions, while allowing one to measure its state variables, using classical methods. Such optimal combination of characteristics is a perfect match for quantum-inspired computing. As an application, an algorithm for global maximum of an arbitrary integrable function is proposed. The idea of the proposed algorithm is very simple: based upon the Quantum-inspired Maximizer (QIM), introduce a positive function to be maximized as the probability density to which the solution is attracted. Then the larger value of this function will have the higher probability to appear.

Genetic Algorithm Optimizes Q-LAW Control Parameters

A document discusses a multi-objective, genetic algorithm designed to optimize Lyapunov feedback control law (Q-law) parameters in order to efficiently find Pareto- optimal solutions for low-thrust trajectories for electronic propulsion systems. These would be propellant-optimal solutions for a given flight time, or flight time optimal solutions for a given propellant requirement. The approximate solutions are used as good initial solutions for high-fidelity optimization tools. When the good initial solutions are used, the high-fidelity optimization tools quickly converge to a locally optimal solution near the initial solution.

Gold-on-Polymer-Based Sensing Films for Detection of Organic and Inorganic Analytes in the Air

A document discusses gold-on-polymer as one of the novel sensor types developed for part of the sensor development task. Standard polymer- carbon composite sensors used in the JPL Electronic Nose (ENose) have been modified by evaporating 15 nm of metallic gold on the surface. These sensors have been shown to respond to alcohols, aromatics, ammonia, sulfur dioxide, and elemental mercury in the parts-per-million and parts-per-billion concentration ranges in humidified air.

Non-Destructive Evaluation of Materials via Ultraviolet Spectroscopy

A document discusses the use of ultraviolet spectroscopy and imaging for the non-destructive evaluation of the degree of cure, aging, and other properties of resin-based composite materials. This method can be used in air, and is portable for field use. This method operates in reflectance, absorbance, and luminescence modes.
