摘要： In an infrared communications link, a transmitter is connected to a plurality of infrared light emitting diodes disposed about an arcuate surface to illuminate a generally rectangular area with pulsed optical energy. When a receiver having a plurality of photodiodes is disposed within the generally rectangular area the information contained in the pulsed optical energy is recovered. The combination of the transmitter and receiver provide a transceiver that is ideally suited for providing two way communication between a fixed station and an automatically guided vehicle in an electromagnetically hostile environment such as a highly automated factory.

摘要： In an apparatus for storing articles, bins have a sensor for detecting the presence of an article in a bin and an optical code reader for reading a bar code on the article. The presence detector and the optical code reader are coupled to a circuit which provides an indication of the identity and location of a coded article. The apparatus is particularly well suited for use in the manufacture of semiconductor devices, when wafer cassette boxes are provided with a suitable bar code. Alternatively, the bins may be disposed upon a remotely guided vehicle, thereby making the apparatus useful in an automated manufacturing process.
