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.

The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
