Abstract: Free-space optical (FSO) wireless transmission, including optical communications, remote-sensing, power beaming, etc., can be enhanced by replacing conventional laser sources that operate in the infrared portion of the optical spectrum with ultra-short pulsed laser (USPL) sources having peak pulse powers of one kWatt or greater and pulse lengths of less than one picosecond. Specifically, it has been observed that under these conditions the attenuation of an USPL beam having the same average optical power as a conventional laser in a lossy medium, such as the atmosphere, is substantially less than the attenuation of a conventional laser beam having a lower peak pulse power and/or a longer pulse width. The superior system performance when using an USPL can be translated into an increased distance between a laser source in a transmitter and a photodetector in receiver and/or a higher reliability of system operation in inclement weather conditions.

Abstract: A sideband communication system has been developed for a conveyor system. A controller card controls the operation of a conveyor zone and communicates information about each conveyor in the conveyor zone. The controller card is assigned to control and monitor the operation of one or more of these zones of conveyors. The cards of adjacent zones are daisy-chained together to facilitate communication with one another and with other systems like a programmable logic controller (PLC). In addition to the standard controller area network (CAN) communication protocol, the controller cards further communicate amongst themselves using a sideband communication protocol that is outside the realm of the standard CAN communication protocol. The sideband communication protocol allows the cards to communicate with each other without interfering with normal network communications which provides additional capabilities such as automatic card self-identification.
