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.

Printed Flexible Solar Cells Provide Embedded Renewable Power

In the effort to produce inexpensive, easily manufactured sources of sustainable, renewable power, solar cells continue to be a major focus — particularly flexible solar cells that can be applied directly to surfaces. Flexible solar cells are nothing new, but the methods by which they are made have progressed significantly in recent years.

Performance of 1mm2 Silicon Photomultipliers

A silicon photomultiplier (SPM) is a new type of semiconductor detector that has the potential to replace the photo- multiplier tube (PMT) detector in many applications. In common with a PMT detector, the output of an SPM is an easily detectable current pulse for each detected photon and can be used in both photon counting mode and as an analogue (photocurrent) detector. However, the SPM also has a distinct advantage over PMT detectors. The photon-induced current pulse from a PMT varies greatly from photon to photon, due to the statistics of the PMT multiplication process (excess noise). In contrast, the current pulse from an SPM is identical from photon to photon. This gives the SPM a distinct advantage in photon counting applications as it allows the associated electronics to be greatly simplified. Identical pulses also mean that the SPM can resolve the number of photons in weak optical pulses, so-called photon number resolution. This is critical in a number of applications including linear-optics quantum computing.

Simulated Models Test Design of Space Shuttles and Rocket Engines

Finite element modeling and analysis Dynamic Concepts Huntsville, AL 256-922-9888 www.dynamic-concepts.com NASA tasked Dynamic Concepts (DCI) with assessing the structural dynamics of the rollout process, whereby the space shuttle orbiter, external tank, and solid rocket booster assembly is moved via a crawler transporter from the Vertical Assembly Building to the launch pad. DCI used Femap finiteelement modeling software from Siemens PLM Software (Plano, TX) to create an integrated model of all the shuttle components, and used Siemens’ NX Nastran to analyze the simulated vibration environment. The analysis helped NASA resolve issues with support structures and determine target rollout speeds that minimized potentially damaging vibration.

PX Series Photoelectric Sensors

The KEYENCE PX Series rugged photoelectric sensors from Keyence Corp. of America, Woodcliff Lake, NJ, feature an IP-69K environmental rating for highpressure (1,400 psi) applications at temperatures to 176°F. They feature stainless steel casings, sensor heads backfilled with epoxy under vacuum conditions, and scratch-resistant lenses. A dual-output feature enables users to see when the sensor activates and when the low-light alarm turns on. A Dynamic Stability Control function continuously and automatically adjusts the set point according to the environmental conditions. Seven water- and oil-resistant sensor heads are available. Ultra-high-intensity LEDs provide power by combining infrared or four-element red LEDs with optical- quality glass lenses. Stainless steel guarded units are available to protect the sensor heads. A Zero-Shift function enables users to adjust the displayed value. For Free Info
