Merit's pressure sensor
Also at the MEC, a new line of high-precision temperature-compensated pressure sensors debuted from Merit Sensor of South Jordan, Utah, which was founded because its parent company -- Merit Medical Systems -- could not find reliable pressure sensors for its cardiology devices. Since then, Merit Sensor has diversified to become a Tier 1 supplier to the automotive, medical, and industrial markets for high-precision, ultra-reliable pressure sensors.

"Our Sentium process utilizes a unique and proprietary packaging strategy that has already been proven out in the medical and automotive industries," said president Rick Russell at MEC. "And our new TR Series continues that tradition with a part that can also serve industrial markets."
Merit Sensor's new high-precision, temperature-compensated TR Series of pressure sensors allow the medium whose pressure is being measured to use a back-side entry that prevents it from ever coming in contact with the top side of the pressure sensing die where the electronics are housed.
Memsic's digital compass
Also at MEC, Memsic Inc. of Andover, Mass., announced a new three-axis magnetometer -- a digital compass -- using its proprietary anisotropic magnetic resistive (AMR) technology, which the company claims employs the Hall effect and giant magneto-resistive techniques used by other manufacturers.
"Our latest three-axis magnetometer builds on the high-resolution, low-noise, and low-power specification of its predecessor," said Paul Miyoshi, director of sales and business development.
The new model, according to Miyoshi, offers four-times better resolution, 25 percent lower noise, and is in a 33 percent smaller package measuring just 1.6 x 1.6 x 0.6 millimeters. Besides providing the digital compass function for smartphones and tablets, Memsic's magnetometer is also aimed at gaming consoles, automotive, and indoor navigation applications.
Kionix's synthetic gyro
Also at the MEC, Kionix announced that its Micro-Amp Magnetic Gyro (KMX61G) had received Windows 8.1 certification, validating that its novel synthetic gyro works as claimed. Traditional gyros are a current sink, running down the battery of mobile devices more than any other MEMS sensor. Kionix's synthetic gyro synthesizes the gyro's rotational information using sensor fusion algorithms on its three-axis accelerometer and three-axis magnetometer, as a result consuming as little as one tenth the power of a traditional nine-axis solution.
