Abstract: A method and system are provided for supporting the growth of algae cells. Initially, an inoculum of algae cells are grown in a closed bioreactor. Thereafter, the inoculum is passed into an open Expanding Plug Flow Reactor (EPFR). Growth medium is added at a plurality of locations along the EPFR. This addition is controlled in response to the growth rate of the algae cells to maintain a substantially same concentration of cells at each location in the EPFR. At all times, the medium provides sufficient nutrients to support growth and maintain a high concentration of algae cells, i.e., at least 0.5 grams per liter of medium, in the EPFR. After the desired level of growth is reached, the algae cells are transferred from the EPFR to a standard plug flow reactor wherein oil production is activated in the algae cells.

Abstract: The present disclosure describes autonomous flight safety systems (AFSSs) that incorporate an autonomous flight termination unit (AFTU) enabling AFSS monitoring for various termination conditions that are used to activate a flight termination system (e.g., in the event a termination condition is detected). Such termination conditions include boundary limit detection (e.g., whether a vehicle position is outside or projected outside a planned flight envelope), as well as body instability detection (e.g., whether a pitch rate and yaw rate exceed some threshold indicative of vehicle instability). For instance, an AFTU may incorporate a three-axis gyroscope sensor and may implement instability detection processing based on information obtained via the sensor. Instability detection processing may include, for example, a BID algorithm that may be implemented by an AFTU to monitor angular rates of the vehicle, to determine if the vehicle is no longer under stable control, and to issue termination commands when termination conditions are detected.

Abstract: Fuel isolation systems, apparatuses and methods are described. In some embodiments, a system comprises a connector coupled inline with a fuel line on a cold side of the fuel line, a valve coupled to the connector, a fluid feed line coupled to a fluid source and to the valve. In the event of an engine fire condition, a control unit outputs signaling to stop pumping the fuel and to operate the valve to introduce fluid from the fluid source into the fuel line. The introduced fluid provides a siphon break in the fuel line such that the only fuel that can pass the firewall is the remaining fuel in the fuel line downstream of the connector and the introduced fluid.
