Sensors: More than MEMS Blog 6/21/2011 2 comments The fact that I spend too much time focusing on consumer electronics was brought home to me vividly by a visit to the recent Sensors Expo 2011 in Chicago. Far from the niche show that I expected, it was swamped by over 4,000 attendees checking out 140 exhibiting companies, making navigating the aisles a good application for GPS, LIDAR, a 3-axis accelerometer and a collision-avoidance system.
ECU architecture ensures failure safety Design How-To 6/17/2011 3 comments The complexity of automotive mechatronic systems makes it impossible to fully determine all potential failure modes or to test all possible behavior. The challenge is to architect control units in a way that dangerous failures are prevented or at least sufficiently controlled.
Touch mania swipes across markets Special Report 6/7/2011 20 comments OEMs are piling on the touchscreen bandwagon, creating an instant ecosystem that could vanish just as fast if LCD makers build the screens into displays.
Plessey's EPIC sensors see thru walls Product News 6/1/2011 2 comments The EPIC sensor, which requires no physical or resistive contact to make measurements, will enable innovative new products to be made such as medical scanners that are simply held close to a patient’s chest to obtain a detailed ECG reading or devices that can ‘see’ through walls.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
