Pandigital, Inc., was a digital photo-frame manufacturer founded in 1998 that around 2010 began to expand its product line to include e-reader, tablets and e-books. Its tablet products included the Planet, Novel, Star, Nova, and SuperNova, and an offline Wikipedia reader called WikiReader .
The act of scanning a photo generally entails something along the lines of placing the photo onto a device, loading some photo software, waiting while the scanner groans away, cropping the ...
Photolithography. Photolithography (also known as optical lithography) is a process used in the manufacturing of integrated circuits. It involves using light to transfer a pattern onto a substrate, typically a silicon wafer . The process begins with a photosensitive material, called a photoresist, being applied to the substrate.
An image scanner —often abbreviated to just scanner —is a device that optically scans images, printed text, handwriting or an object and converts it to a digital image. Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning.
The photodetector contains three photodiodes, visible in the photo (in center). Photodetectors, also called photosensors, are sensors of light or other electromagnetic radiation. [ 1] There are a wide variety of photodetectors which may be classified by mechanism of detection, such as photoelectric or photochemical effects, or by various ...
The oldest optical-scan voting systems scan ballots using optical mark recognition scanners. Voters mark their choice in a voting response location, usually filling a rectangle, circle or oval, or by completing an arrow. Various mark-sense voting systems have used a variety of different approaches to determining what marks are counted as votes.
Iris recognition biometric systems apply mathematical pattern-recognition techniques to images of the irises of an individual's eyes.. Iris recognition is an automated method of biometric identification that uses mathematical pattern-recognition techniques on video images of one or both of the irises of an individual's eyes, whose complex patterns are unique, stable, and can be seen from some ...
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.
