  • Patent number: 11923801
    Abstract: Features for a solar generation system. The system includes a solar generator that may be installed on a shipping container. The solar generator includes one or more deployable rotating solar arrays. The rotating solar arrays may be deployed and stowed using actuators. The rotating solar arrays may be stowed for transport of the system on ships or to remote locations. The solar panels of the array are unexposed when stowed. A base frame with corner castings may attach to standard connections on cargo containers. The solar generators may be stacked on top of each other when stowed for transport. An actuation system may include linear actuators with two arms connecting at a moving pivot point that attach to a base frame and to the panels for deployment. Another actuation system may include end-mounted linear actuation arms with panel backside-mounted deployment arms.

  • Publication number: 20230055859
    Abstract: A decoder for the MIL-STD-1553B bus which operates at a slower clock rate than the 40 MHz industry standard clock rate. This embodiment uses a 10 MHz clock rate. Because the clock rate is slower than the 40 MHz clock rate, the invention will inherently use less power. Additional features of this invention include: flexible resolution timestamp input, error checking and reporting throughout the decode process and 32 bit buffered parallel output of the bus controller and remote terminal communication. In another embodiment the decoder has a plurality of n ancillary clocks which provide partial state timestamps, which are summable to create a system timestamp.
