  • Patent number: 7138903
    Abstract: A lock module includes a transmitting module to continuously transmit multiple colored light rays, a key adapted to be inserted into the keyhole of the lock and having multiple colored optical lenses each permitting a specific colored light ray to pass therethrough and a receiving module to receive, store and compare the colored light rays from the multiple colored optical lenses to identify whether the key inserted into the keyhole is accurate. After an initial process of storing the sequence of the colored light rays by the receiving module, the receiving module is able to use stored information to compare the colored light rays subsequently passing through the colored optical lenses of another key to check whether the subsequent key is the accurate key.

  • Patent number: 6816647
    Abstract: An industrially hardened terahertz electromagnetic transmitter and receiver module (29) is disclosed. The electromagnetic wave module has an optic (30) which relays an optical pulse from the delivery fiber (32) to the terahertz device. The relay optic (30) allows for a greatly reduced optical spot size as compared to the output of the optical fiber. Thus, the sensitivity of the overall system is enhanced by improving the efficiency of the terahertz device. The relay optic (30) allows the small spot of light to be aligned to the electromagnetic transmitter or receiver with sub-micron precision.
