What is ultrasound? "Ultra" is a Latin word meaning “beyond,” or “on the far side of,” so “ultrasound” simply means sound which is too high for humans to hear. This is typically considered to encompass frequencies above 20 kHz (20,000 cycles per second). The hearing of dogs and bats extends into this ultrasonic range. Ultrasound is a wave, like light or radio waves. It’s … [Read more...] about Ultrasound Expert Witness: What Ultrasound is and How It Works

MEMS Expert Witness: What are MEMS and How are They Used in Modern Technology?
What are MEMS? “MEMS” is an acronym standing for Micro-Electro-Mechanical Systems. These are tiny mechanical devices which are made in integrated circuit (IC) factories. When the technologies for electronic chips were developed, there was an unanticipated parallel benefit: the ability to precisely manufacture mechanical devices with very small features. The celebrated … [Read more...] about MEMS Expert Witness: What are MEMS and How are They Used in Modern Technology?
Biometric Security Expert Witness: How Technology and Biology Combine to Improve Security and User Experience
What is Biometric Security? “Biometrics” refers to measurements related to human physical or physiological characteristics, such as a fingerprint. A Biometric Security system controls access to a location, computer system or account data by sensing an aspect of an individual and matching that measurement to a database of registered users of the system. As a biometric … [Read more...] about Biometric Security Expert Witness: How Technology and Biology Combine to Improve Security and User Experience
Transducer Expert Witness: What a Transducer is and How it Works in Medical Devices
What is a transducer? The word “transducer” comes from the Latin verb transducere, meaning “to transfer.” A transducer transfers one type of energy to another. Modern technology uses electrical signals extensively, so today’s transducers often convert electricity into some other type of energy. An everyday example is a loudspeaker, which produces sound waves when driven … [Read more...] about Transducer Expert Witness: What a Transducer is and How it Works in Medical Devices
