Abstract: A cardboard package has a cardboard container and a cardboard tray. The cardboard container has a first recess in the first wall and a second recess in the second wall. The cardboard container further has a first protrusion on the first wall, the first protrusion extending inwardly from the first wall, and positioned proximal of the first recess. The cardboard tray has a first wall having a first tab and a second wall having a second tab, the second wall opposing the first wall, the first and second tabs each having a shape and a position selected such that the first and second tabs cannot extend through the first and second recesses respectively when the package is in a closed position. A tab is further shaped and positioned to engage the first protrusion in the cardboard container to prevent the container from falling out.

Abstract: The technology employs a state-based power control loop (PCL) architecture to maintain tracking and communication signal-to-noise ratios at suitable levels for optimal tracking performance and data throughput in a free-space optical communication system. Power for a link is adjustable to stay within a functional range of receiving sensors in order to provide continuous service to users. This avoids oversaturation and possible damage to the equipment. The approach can include decreasing or increasing the power to counteract a surge or drop while maintaining a near constant received power at a remote communication device. The system may receive power adjustment feedback from another communication terminal and perform state-based power control according to the received feedback. This can include re-initializing and reacquiring a link with the other communication terminal automatically after loss of power, without human intervention.

Abstract: The disclosure provides for a method for reacquiring a communication link between a first communication device and a second communication device. The method includes using one or more processors of the first communication device to receive historical data related to the first communication device and an environment surrounding the first communication device. The one or more processors are then used to determine one or more trends in the historical data related to fading of the communication link. Based on the one or more trends, the one or more processors are used to determine a starting time and an initial search direction for a search for the communication link. The one or more processors then execute the search at the starting time from the initial search direction.
