The KDAQ200+ is the first in a new line of products that make it easier
to use analog sensor products with USB interfaces. The KDAQ200+ has
two high resolution differential AD inputs along with a thermocouple input for
reading the sensors and allowing the user to compensate for thermal effects on
the transducers. However, what puts the plus in the KDAQ200+ is
how it uses the USB power to derive a clean programmable +/-5V to +/-24V supply
voltage that can be used to power legacy sensor systems. Using the KDAQ200+ and
the supplied software, engineers can quickly connect up sensor systems and
begin logging data immediately. The KDAQ200+ essentially "USB
enables" analog transducer systems such that the power supply, data
acquisition, and logging functions are in a clean integrated package.
This allows engineers to use battery powered laptops and notebooks directly
with analog transducers with no need for external supplies to power
them. Because the supply can supply a bipolar voltage it can work
with many legacy transducers. The additional thermocouple input also
allows the user to evaluate and deal with environmental effects. There are
many USB data loggers and acquisition systems on the market. What makes
this product different is that it also acts as a programmable bipolar power
supply completely powered by the USB port. This allows an analog
transducer to truly become "USB enabled" where the unit is powered by the USB
port and data collected over the USB port. With notebook PC's becoming
ubiquitous it makes it easy and low cost to set up for data logging.

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.
