The game Scan Command: Jurassic Park was considered unique for its use of which device that consists of a light source, a lens and a light sensor translating optical impulses into electrical ones?
Barcode reader A barcode reader (or barcode scanner) is an electronic device that can read and output printed barcodes to a computer. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain "decoder" circuitry analyzing the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.
Logic probe A logic probe is a hand-held pen-like test probe used for analyzing and troubleshooting the logical states (Boolean 0 or 1) of a digital circuit. While most are powered by the circuit under test, some devices use batteries. They can be used on either TTL (transistor-transistor logic) or CMOS (complementary metal-oxide semiconductor) integrated circuit devices.
