Unveiled last year by the U.S. Department of Energy's National Renewable Energy Laboratory (NREL), the Large-Volume Battery Calorimeter (LVBC) is a crucial tool in helping automakers get the batteries they need for the next generation of electric vehicles that can deliver the range, performance, reliability and safety drivers expect. The LVBC is designed to precisely measure … [Read more...]
NASA Investigates Use of Heat Pipes on Space Station
Scientists launched an investigation called the Constrained Vapor Bubble, or CVB, to the International Space Station to look into the operation of a heat pipe in space. The Constrained Vapor Bubble is the prototype for a wickless heat pipe and is the first full-scale fluids study in the Fluids Integrated Rack or FIR facility flown on the U.S. module of the space station. Nearly … [Read more...]
Nanotechnology Converting a Car’s Waste Heat into Electrical Power
Up to 60 percent of each $4 gallon of gas is wasted, lost as heat that pours out of the exhaust pipe. The technology to collect some of that heat and convert it back into electricity that can recharge the battery exists, but it’s still a work in progress. The solution lies in thermoelectric devices. A material whose response to a change in temperature generates electric … [Read more...]
Compact Linear Laser Diode Driver Supports Fiber-Coupled Lasers
Wavelength Electronics’ PLD-CH Series is now available in a 12.5 A model. This new driver supports fiber-coupled lasers used in applications such as medical, dental, micro-machining, material processing, semiconductor inspection, and imaging. The PLD-CH Series offers single-supply low voltage operation from +5 V DC, which minimizes heat dissipation. For applications that … [Read more...]
Low Resistance Connector with Silicone Core
Fujipoly’s Zebra® Gold 8000C Series product is constructed from a low durometer silicone core that is covered with 166 parallel rows of flat, gold-plated wires per inch. This construction allows the connector to accommodate PCBs with pad center spacing down to .020”. In addition, each .001” x .003” gold-plated copper element delivers a current carrying capacity of 250mA while … [Read more...]
