First, the Wearables Wearables – small electronic devices worn next to clothing to record personal data – have insinuated themselves into the lives of millions of people. After Google Glass, Fitbit and the Apple Watch, the marketplace has become crowded and designs are maturing. Capabilities such as the ability to measure heart rate by optical means (see figure 1) now work … [Read more...] about Wearable Device Expert Witness: Here come the Hearables
Medical Device Expert Witness: How Technology Saves Lives
Engineering inventions to improve health date back at least to 1850, when the famous physicist Hermann von Helmholtz devised the ophthalmoscope. One of the first medical devices, it allows a doctor to look at the interior of a patient’s eye. In the latter part of the 20th century the pace of innovation in medical devices increased dramatically, with a global market size … [Read more...] about Medical Device Expert Witness: How Technology Saves Lives
Signal Processing Expert Witness: What Signal and Image Processing Are, and How They Are Used
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 every high-tech product … [Read more...] about Signal Processing Expert Witness: What Signal and Image Processing Are, and How They Are Used
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 motivated by two factors: Processors … [Read more...] about Parallel Computing Expert Witness: What Parallel Computing Is and How It Is Used
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 (perhaps to … [Read more...] about ASIC Expert Witness: What an Application Specific Integrated Circuit is and How They are Used
