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.
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 largest feature of the parking lot is its paved area, hence, by changing this surface to be more permeable to water the parking lot will drain better. Some surface options are open joint pavers, porous asphalt, pervious concrete, or a turf grid. Drainage may be an important part of a green parking lot because runoff is often a serious concern.
A photoresist (also known simply as a resist) is a light-sensitive material used in several processes, such as photolithography and photoengraving, to form a patterned coating on a surface. This process is crucial in the electronics industry. [1] The process begins by coating a substrate with a light-sensitive organic material.
A photopolymer or light-activated resin is a polymer that changes its properties when exposed to light, often in the ultraviolet or visible region of the electromagnetic spectrum. [1] These changes are often manifested structurally, for example hardening of the material occurs as a result of cross-linking when exposed to light.
