How can sensors help you fly inside a building?

April 17, 2018 By Randy Frank Leave a Comment

How can sensors help you fly inside a building?

Due to gravity, when skydivers jump out of an airplane, they immediately fall toward the earth, falling several thousand feet in less than a minute before opening their parachutes. For indoor skydiving, where you float less than 100 feet above ground level, there is no parachute and a rather sophisticated process is involved that uses […]

What advanced sensing techniques are used to find lost treasures? Part 5: LiDAR

April 16, 2018 By Randy Frank Leave a Comment

What advanced sensing techniques are used to find lost treasures? Part 5: LiDAR

This series has previously addressed magnetometry, electromagnetic induction , ground penetrating radar and resistivity measurements. LiDAR (Light Detection and Ranging) is another sensing technique frequently used by archeologists and treasure hunters to find objects. While it can be used alone, it is often combined with electromagnetic induction, magnetometry and/or electrical resistivity measurements. LiDAR data analysis […]

What advanced sensing techniques are used to find lost treasures? Part 4: Resistivity measurements

This series has previously addressed magnetometry, electromagnetic induction and ground penetrating radar. Another sensing technique frequently used by archeologists and treasure hunters to find objects involves resistivity measurements. Unlike other sensing techniques, resistance measurements involve inserting metal probes into the ground rather than non-invasive surface measurements. Since electrical currents are conducted through the soil by […]

What advanced sensing techniques are used to find lost treasures? Part 3: Ground penetrating radar

This series has previously addressed magnetometry and electromagnetic induction. While both of these sensing techniques are frequently used by archeologists and treasure hunters to find objects, they are often combined with ground penetrating radar (GPR) to improve the search results. Compared to other commonly available geophysical methods, GPR is the only one that provides true […]

What advanced sensing techniques are used to find lost treasures? Part 2: Electromagnetic induction

March 27, 2018 By Randy Frank Leave a Comment

What advanced sensing techniques are used to find lost treasures? Part 2: Electromagnetic induction

Part 1 of this series addressed magnetometry. Another sensing technique used by archeologists and treasure hunters to find objects is electromagnetic induction (EMI or EM). EMI sensing measures the change in mutual impedance between a pair of coils on or above the earth’s surface. Typical EMI instruments use two or more sets of coils, electrically […]

What is Beer’s Law?

March 17, 2018 By Randy Frank Leave a Comment

What is Beer’s Law?

No. It has nothing to do with drinking too many beers and getting a beer belly. Named after German mathematician and chemist, August Beer, Beer’s law (or the Beer-Lambert law) observes the linear relationship between absorbance and concentration of a dissolved substance in a solution and is usually expressed as: A = a(λ) * b […]

What role does sensing play in bike-sharing?

February 28, 2018 By Randy Frank Leave a Comment

What role does sensing play in bike-sharing?

They’re green. They’re yellow and many other very obvious colors. And, if they are in your town, they seem to be everywhere. Bike-sharing has become a high-volume business for companies with unusual names, like Ofo, Didi Chuxing, Mobike, LimeBike, and more. According to Ofo’s website, the process simply consists of: “Find it. Scan it. Ride […]

What is an aphrometer?

February 27, 2018 By Randy Frank Leave a Comment

What is an aphrometer?

In simple terms, an aphrometer is a manometer for measuring the pressure in champagne and sparkling wine bottles. When the aging process is completed, a disgorgement process removes the sediment and then an aphrometer is used to check the pressure in the bottle. Traditional cork and crown cap aphrometers make invasive measurements, typically in the […]
