What is Signal and Image Processing? Signal Processing and Image Processing sound like arcane mathematics, but they only appear that way because they operate under the hood as “stealth” technologies. Both are used for many down-to-earth and practical jobs. While not as visible as self-driving cars or cell phones, they are critical for just about […]

Parallel Computing Expert Witness: What Parallel Computing Is and How It Is Used
What is Parallel Computing? Parallel computing is a simple concept: it is using more than one processor (or CPU) to complete a data processing task. A couple of decades ago, parallel computing was an arcane branch of computer science. Now, it is everywhere—in cell phones, web sites, laptops and even wearables. This radical shift was […]
ASIC Expert Witness: What an Application Specific Integrated Circuit is and How They are Used
What is an ASIC? An application-specific integrated circuit (ASIC) is a type of integrated circuit built for a specific application or purpose. This is in contrast to general-purpose integrated circuits, known in the industry as Standard Products, such as microprocessors or memory chips. Figure 1 shows the layout of an ASIC which includes analog circuits […]
Ultrasound Expert Witness: What Ultrasound is and How It Works
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 […]
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 physicist Richard Feynmann may […]
