In electronic signal processing, a square law detector is a device that produces an output proportional to the square of some input.
Square law detection is a method used in communication systems to demodulate analog signals. It relies on multiplying the input signal with itself to obtain the power of the signal, which contains information about the original signal. This method is commonly used in amplitude modulation systems for recovering the original message signal.
Graham's law of effusion states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. In other words, lighter gases effuse or diffuse at a faster rate than heavier gases under the same conditions.
Prohibition laws in the United States in the 1920s. They were hidden, underground bars where alcohol could be served illegally. Patrons would speak quietly ("speak easy") about their activities to avoid detection by law enforcement.
Newton's Law of Universal Gravitation states that every particle in the universe attracts every other particle with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. The Law of Conservation of Energy states that energy cannot be created or destroyed, only transferred or converted from one form to another. Boyle's Law describes the inverse relationship between the pressure and volume of a gas at constant temperature.
Coulomb's law states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Mathematically, it is represented as F = k * (q1 * q2) / r^2, where F is the force, k is the proportionality constant, q1 and q2 are the charges, and r is the distance between the charges.
Worthington's law, also known as the 2/3 power law, is an engineering principle that specifies the relationship between the velocity and drag force of a falling sphere in a fluid medium. It states that the drag force on a falling sphere is proportional to the square of its velocity, with the drag coefficient being inversely proportional to the sphere's velocity raised to the power of 2/3.
When it detects a face it focuses on it & usually puts a square on it when they are smiling
The law is called The Inverse Square Law .
It depends which section of law you mean. Technology has greatly improved the detection rates of crime, through developing DNA fingerprinting for example.
Edge detection generally applies to a square wave signal, such as a clock pulse or a trigger pulse. Then the edge detection comes from either using the rising voltage, or the falling voltage of the signal (usually a square wave) to trigger the next event. Using the falling voltage implies a delay in the signal and the rising pulse to trigger an immediate `step` in the circuit.
A FET is called a square-law device because of the relationship of ID to the square of a term containing VGS.
Dog handlers for narcotics detection dogs are first and foremost law enforcement officers. Handlers are chosen from within departments for additional training to be partnered with a narcotics detection dog.
The law is that the attraction between electric charges is inversely proportional to the square of the distance. Note that the way the force varies with distance is identical to the gravitational force, which also follows an inverse-square law.

Employers risk detection and being fined large sums of money for violating federal law.

Charles Augustin de Coulomb is credited with the discovery of the inverse square law. It was used by Isaac Newton in his prismatic experiments.
any physical law stating that some physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity.
