PIC (usually pronounced as /pɪk/) is a family of microcontrollers made by Microchip Technology, derived from the PIC1640 [ 1][ 2] originally developed by General Instrument 's Microelectronics Division. The name PIC initially referred to Peripheral Interface Controller, [ 3] and is currently expanded as Programmable Intelligent Computer. [ 4]
For distributed temperature sensing often a code correlation technology [2] [3] [4] is employed which carries elements from both principles. OTDR was developed more than 20 years ago and has become the industry standard for telecom loss measurements which detects the—compared to Raman signal very dominant— Rayleigh backscattering signals.
Intelligent street lighting. Intelligent street lighting refers to public street lighting that adapts to movement by pedestrians, cyclists and cars in a smart city. [ 1] Also called adaptive street lighting, it brightens when sensing activity and dims while not. This is different from traditional stationary illumination, and that which dims on ...
These common lighting qualms have to do with the color temperature of the light bulbs. While many people may look at wattage (i.e., the amount of energy that a bulb uses to produce light) before ...
Infrared thermometer. An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called black-body radiation emitted by the object being measured. They are sometimes called laser thermometers as a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns ...
A closeup of a 175- W mercury vapor lamp. The small diagonal cylinder at the bottom of the arc tube is a resistor which supplies current to the starter electrode. A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce light. [ 1] The arc discharge is generally confined to a small fused quartz ...
Resistance thermometer. Resistance thermometers, also called resistance temperature detectors ( RTDs ), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a heat-resistant ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum (Pt ...
Correlated color temperature. Log-log graphs of peak emission wavelength and radiant exitance vs black-body temperature, plotted on the blue line. Red arrows show that 5780 K black bodies have 501 nm peak wavelength and 63.3 MW/m 2 radiant exitance. Correlated color temperature ( CCT, T cp) refers to the temperature of a Planckian radiator ...
