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.
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.
