What is sensor fusion?

When a colleague of mine recently asked me “What is sensor fusion?” I had to stop and think. Like Justice Potter Stewart once said, “I know it when I see it.” But as an engineer dealing with this topic every day, I should be able to do better. Eventually I came up with the following:

Sensor fusion encompasses a variety of techniques which can:

  • Trade off strengths and weaknesses of the various sensors to compute something more than can be calculated using the individual components;
  • Improve the quality and noise level of computed results by taking advantage of:
    • Known data redundancies between sensors
    • Knowledge of system transfer functions, dynamics and/or kinematics

Good lord! Sounds like something out of one of my textbooks. It’s more fun to look at it by example.

MEMS in Vegas, Baby

The Consumer Electronics Association (CEA) has a new dance partner—and we’re it! For the first time, MEMS has an official home at CES. MEMS Industry Group (MIG) is pleased to host the brand-new MEMS TechZone and the only MEMS conference program at CES 2012.

MEMS TechZone is a new area of the show floor for companies that are driving the adoption of this exciting technology in mobile phones, game consoles, tablet PCs and other hot consumer-electronic devices. MIG will co-exhibit with several members including Bosch/Bosch Sensortec/Akustica, VTI Technologies and WiSpry. Please contact Karen Lightman if you are interested in co-exhibiting opportunities.

Plan to visit the MEMS TechZone at the LVCC, South Hall 2—and join us for a panel on consumer devices enabled by MEMS which you will NOT want to miss on Wednesday January 12 at 11:30 am in room N254, North Hall of the Las Vegas Convention Center. Register in advance for a special discount!

Stay tuned for more MIG news on MEMS programs/events at CES 2012.
