Gleichmann Electronics' SD746 combo sensor from SensorDynamics has three measurement axes each for angular rate and acceleration as
well as a wide measurement range of up to Â±2048Â°/s for angular rate and Â±8 g
The inertial sensor is 6 x 6 x 1.2
mm3 and the maximum offset error at room temperature is Â±5Â°/s for
the gyroscope signal and Â±0.1g for the accelerometer signal. Sensitivity error
at room temperature is Â±2 percent for the gyroscope and acceleration signal,
respectively. Additional features of the SD746 include a special power-off mode in which no power is consumed,
but the SPI interface remains high-impedance and a continuously running self-test.
The micromechanical combo sensor
is provided in a compact QFN40 package and is designed for an operating voltage
of 2.55 to 3.6 V and an operating temperature range of -40 to +85C. The typical
power consumption is 6.5 mA.
The SD746 combo sensor is suitable for use both in battery-powered
consumer applications and sophisticated industrial instrumentation and control
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
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.
