How do ear recognition biometrics work?
In the era of face masks, ear recognition can provide a viable alternative to more commonly used facial recognition. The human ear remains relatively unchanged, making it suitable for security authentication applications. It can also be easier to extract information from since it is not subject to variations like facial expressions. Ear recognition biometrics analyze […]
How do body odor recognition biometrics work?
A body odor recognition system uses an electronic nose (E-nose) with numerous chemical sensors to detect and identify volatile organic compounds (VOCs) in the air. General-purpose E-noses are available to detect and identify complex chemical mixtures that constitute aromas, odors, fragrances, and formulations. Breathalyzers are specialized E-noses used to measure the amount of alcohol in […]
IP67-rated magnetic encoder serves construction and medical equipment uses
Novotechnik, U.S. introduces the MC-1 2800 44-Turn magnetic encoder with IO-Link output interface. Patented non-volatile technology retains turn count even when power is lost and reports correct count when power is restored. Key specifications for the MC-1 2800 include a measuring range of 15,840° (44 turns), and measured variable information of angle, turns, speed, and […]
