Sensors Unlimited SDV Short-Wave Infrared Camera. Engineers mated their recently developed, large, indium gallium arsenide (InGaAs) imaging array with a low-cost silicon CMOS readout circuit to enable this compact short-wavelength (1-2.5 microns) infrared camera. They used matching grids of indium bumps on the bottom of each circuit's substrate to connect the detector and multiplexer readout, forming a back-to-back stack. By not having to cool the 640 x 512 pixel InGaAs detector, the engineers eliminated bulky cooling devices necessary with longer-wavelength IR cameras, along with their expensive germanium or silicon lenses.

HIGH-WATTAGE MOTOR POWERS BLENDER
L'Equip® Model 228 R.P.M. Blender. To give users the power to beat-up any vegetable or fruit, inventor Jamie Pascotti propels his blender with a 900W LG (http://rbi.ims.ca/3852-542) universal ac motor, more than three times as strong as the usual 250W blender motor. He notes the appliance's tachometer "shows motor speed to the user in real time," allowing for more precise blending control than conventional "vague" pushbutton settings. For most efficient motor operation, the size, shape, and position of the beads (vertical ribs molded into the polycarbonate pitcher sides) relative to the rotating blades are critical for best mixing action, Pascotti adds.

PIEZOS, ALGORITHMS PACE PEDOMETER
OMRON Healthcare HJ-112 Premium Pedometer. Twin piezo sensors, mounted 90 degrees to each other, ensure this pedometer generates one or two walking "signals" as long as the device's orientation is not perfectly horizontal. Engineers had to develop waveform-analysis and step-counting algorithms that would run on a low-power, 4-bit microprocessor, but still eliminate noise signals, such as vehicle vibrations or non-periodic body-movement acceleration. To account for the latter, the software determines periodicity of a waveform, then starts recording steps that last longer than four seconds.

Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
