It's revenge of the NURBS for mega-yacht design
The style of Delta Marine Industries' fully custom yachts combines classic sophistication with the modern curves that could only come from today's most advanced design and production techniques. The Rhinoceros modeling software, now used throughout the marine industry, allows Delta designers to easily generate streamlined nautical features ready for both fine rendering and accurate CNC manufacture. The Rhinoceros modeler is based on NURBS — the name for curved surfaces described by mathematic equations.

Shedding some light on machine vision Machine vision certainly is not new, but for first-time users, the wide range of unfamiliar products and technologies can be daunting. Reluctance to adopt these new technologies is largely caused by uncertainty. One way that vision system vendors have dealt with the problems of component selection has been to develop complete off-the-shelf vision solutions. Read the full article Linear Motor Ready to Plug & Play MicroMo introduces QUICKSHAFT, a linear motor that combines the speed and robustness of a pneumatic system with the flexibility and reliability features of a linear motor. The innovative design with a 3-phase self-supporting coil and non-magnetic steel housing offers outstanding performance, ideal for micropositioning applications. For more information visit MicroMo online. Simulation solves thermal challenges in world's fastest supercomputer CH2M HILL engineers used Flomerics' Flovent computational fluid dynamics (CFD) software to simulate predicted thermal loads generated by the IBM Roadrunner machine to be installed at Los Alamos National Laboratory's Nicholas Metropolis Center. By regularly modeling the facility, CH2M engineers have helped the Department of Energy stay one step ahead of the continuously increasing thermal load while minimizing initial and operating costs of cooling equipment.

NIST aims for boost in heat pump output Air-source heat pumps typically deliver 1 1/2 to three times more heating energy to a home than the electric energy they consume. This is possible because heat pumps move heat rather than convert it from a fuel (as combustion heating systems do). National Institute for Standards and Technology researchers are working to improve the performance of these energy superstars even further by providing engineers with computer-based tools for optimizing heat exchanger designs. Read the full article Electric Replacement for Hydraulics! Exlar's electric linear actuators deliver the force of hydraulics and the speed of pneumatics. The patented roller screw technology offers peak forces in excess of 40,000 lbf., speeds to 60 in/sec, and stroke lengths to 96 inches, all with the ease and reliability of servo control. Visit Exlar online for more information.

5-Star Product: Pressure sensor built to survive
Stellar Technology's Model GT100 is a robust, heavy-duty pressure transducer designed as a solution to severe applications like rocket engine testing that can ruin a typical pressure sensor. Model GT100 features a cleanable pressure cavity and a stainless steel diaphragm that can be replaced in the field as needed.

Engineer's Toolbox: Novel wireless sensor power prototype a hot idea
The TE-Power-Bolt is a voltage-adjustable thermal battery that uses excess heat to generate electrical energy for devices that consume only a few milliwatts of power, such as wireless sensor nodes. With its micro-thermogenerator, the Power-Bolt can harvest energy from surfaces and structures from 10°C to 20°C over ambient temperature or directly from hot liquids.
