Fotomat was an American retail chain of photo development drive-through kiosks located primarily in shopping center parking lots. Fotomat Corporation was founded by Preston Fleet in San Diego, California, in the 1960s, with the first kiosk opening in Point Loma, California, in 1965.
Edison Properties is a privately owned real estate holding and development firm based in Newark, New Jersey founded in 1956. [1] [2] [3] The company has holdings in New Jersey, New York City, and Baltimore including many parking lots marketed under ParkFast and storage units marketed under Manhattan Mini Storage.
Although the tower lighting in Detroit provided "uniform carpets of light", it was ineffective in providing sufficient lighting for high-traffic areas and routes. After five years, Detroit began to dismantle its towers. [1] As of October 2021, the only lighting towers that remain in the United States are in Austin, Texas.
Three photoresistors with scale in mm Large CdS photocell from a street light. A photoresistor is less light-sensitive than a photodiode or a phototransistor.The latter two components are true semiconductor devices, while a photoresistor is a passive component that does not have a PN-junction.
Opto-isolator VTL2C1 with LED input and photoresistor output. Resistive opto-isolator (RO), also called photoresistive opto-isolator, vactrol (after a genericized trademark introduced by Vactec, Inc. in the 1960s), analog opto-isolator [notes 1] or lamp-coupled photocell, [1] is an optoelectronic device consisting of a source and detector of light, which are optically coupled and electrically ...
The most common use of such light meters is measuring the exposure value for photography. The electric part of such a meter is an electromagnetic measuring instrument which is connected to the anode and cathode of a selenium photo cell that produces more or less electric power when exposed to more or less light. The optical part of such a meter ...
Monocrystalline solar cell This is a list of notable photovoltaics (PV) companies. Grid-connected solar photovoltaics (PV) is the fastest growing energy technology in the world, growing from a cumulative installed capacity of 7.7 GW in 2007, to 320 GW in 2016. In 2016, 93% of the global PV cell manufacturing capacity utilized crystalline silicon (cSi) technology, representing a commanding lead ...
A phototube or photoelectric cell is a type of gas-filled or vacuum tube that is sensitive to light. Such a tube is more correctly called a 'photoemissive cell' to distinguish it from photovoltaic or photoconductive cells. Phototubes were previously more widely used but are now replaced in many applications by solid state photodetectors.
