Abstract: A method and system for wireless communication in a conveyor system. The method includes: formulating a command from a master controller to an accessory controller; translating the command into a simplified protocol; transmitting the simplified command via a wireless communications channel; receiving the simplified command at a wireless receiver; processing the simplified command by the accessory controller; formulating a response to the master controller from the accessory controller; transmitting the response via the wireless communications channel; and translating the response for handling by the master controller. The system includes: a downlink converter/transmitter configured to translate a command into a simplified protocol and send a simplified command via a wireless signal; an accessory receiver/transmitter configured to receive the wireless signal; and an accessory interface configured to communicate the simplified command to the accessory for execution.

Abstract: A system and method for providing power to moving elements on a conveyor system while the moving elements are moving. An accessory for mounting on one or more of the moving elements, which receives power from the system. Various accessories for using the power provided. In one case, the accessory is a rotary gripper that includes a body; a gripper motor; a rotation motor; and a plurality of grippers, wherein the gripper motor is mechanically connected with and configured to open and close the plurality of grippers, the rotation motor is mechanically connected with and configured to rotate the plurality of grippers. Other accessories include a gripper, a vacuum system, a heater, and a cooler.

Abstract: A laser cavity includes two half shells adapted to be held together forming a sealed, integrated laser structure. The laser cavity is adapted for retaining an excitation source and a lasing medium. At least one coolant passage formed in at least one of the half shells causes liquid to flow transversely over the excitation source and lasing medium. At least one coolant passage formed in at least one of the half shells removes liquid from the laser cavity after the liquid is caused to flow transversely over the excitation source and lasing medium. An inlet formed in at least one of the two half shells can transport liquid into the laser cavity and through the coolant passages. An outlet formed in at least one of the two half shells can remove coolant from the laser cavity after the liquid is caused to flow transversely over the excitation source and lasing medium.
