LED Driver

Innovations in Optics, Inc. (Woburn, MA) has introduced the Model 5000A-100 LED Driver/Controller for powering its patented and patent-pending High Power LED Light Engines. The 5000A-100 LED Driver provides constant current in continuous, pulsed or pulsed width modulation (PWM) modes. An embedded system adds network control with 10/100Mbps Ethernet connectivity. The Model 5000A- 100 is intended for OEM applications. Drive current in continuous mode is selectable from 7.5 to 75A at 0.6 to 5.5VDC output. The output current setting is adjustable either locally or remotely from 100% down to 10% using analog adjustment and as low as 1% with PWM.

Intelligent Lighting System

The BrainLight series by EVT (Karlsruhe, Germany) is an intelligent lighting system that allows the user to control both color and brightness, as well as create and save individual lighting patterns. At present the BrainLight series consists of a back light (BrainLight QC) and a ring light (BrainLight R). The back light has separately controllable rows of red, green, blue and white LEDs. There is a diffuser glass in front so the light spreads evenly over the object. All in all there are 48 LEDs, arranged in a grid. The size is 30 x 40 mm, but extra rows of LEDs can be added. The ring light has a RS232 or TTL UART interface and a +5V or 12-24V input voltage. The LEDs are separated into 8 segments each with 3 LEDs.

Coming Soon - Increasing Tier 4 Efficiencies via Systems Integration

In conjuction with SAE With a victory over Tier 4 emissions regulations achieved across the off-highway industry, engines manufacturers, OEMs, and other system suppliers now must find other ways to differentiate themselves and gain competitive advantages over rivals. The main way to do that is to collaborate on increasing system efficiencies along the entire lifecycle of a vehicle and its components via optimum systems integration.

Position Sensor Technology for Hydraulic Cylinder Feedback

Variable inductance sensors offer a cost-effective option for mainstream, in-cylinder applications. Alliance Sensors Group, a Division of H.G. Schaevitz LLC, Moorestown, New Jersey Position feedback sensors for hydraulic or pneumatic cylinders have used one of three traditional technologies: magnetostrictive, variable resistance, and variable inductance. As the demand for increased control and functionality has increased, sensor-instrumented cylinders are becoming more important in the heavy industry, subsea, and mobile equipment worlds. Ultimately, a user or systems integrator must determine the requirements of the application and which technology best satisfies it on a total installed cost versus performance basis. The strengths and weaknesses of magnetostrictive, variable resistance, and variable inductance sensors are shown in the figure. These common sensing technologies utilize a long probe that extends into a deep, small-diameter blind hole that has been gun-drilled into the internal end of the cylinder rod.

Detection of Gases and Vapors Present at Low Concentrations

Ames Research Center, Moffett Field, California A nanostructure-based mechanism was developed for sensing the presence of, and estimating concentration values of, specified chemical components in a sample gas to which the mechanism is exposed, where the concentrations may be as low as five parts per billion. The mechanism receives a sample gas, converts the gas information received to a change in an electrical parameter value (EPV) sensed at each of an array of separately functionalized carbon nanotubes (CNTs), estimates which of a group of specified chemical components is present and the associated chemical concentrations in the sample gas, formats information concerning the chemical components sensed in the sample gas, and transmits this information to selected recipients. The specified chemical components and the corresponding concentration values are displayed on a cellphone screen, a tablet screen, or a computer screen. Optionally, the information is compensated by removing the effects of the presence of ambient gas components that are not of concern in the sample gas.
