Abstract: A fail-safe drug infusion system, including a user interface controller (UIC) and at least one pump motor controller (PMC), with protocols that enable the PMC to operate therapy delivery for a limited amount of time if the UIC fails or the communication link between the UIC and the PMC is interrupted. Includes synchronization methods to synchronize the delivery information back to the UIC after the UIC reboots or after the communication link is restored. The PMC may apply intelligent fail-safe drug infusion therapy by temporarily displaying therapy information, for example information normally displayed by the UIC, while taking control of alarm signaling and providing minimal user control of the therapy until the UIC restores itself, the infusion completes normally, or the user stops the infusion. If the PMC becomes inoperable, the UIC may wait for the PMC to reboot, or attempt to switch infusion channels to provide robust drug infusion.

Abstract: Embodiments of a hydroponic growing system include raft segments that can be reversibly attached together to form a raft. Rafts can have one or more plant holes to support a plant body, and one or more thermal chimneys to provide for gas transport from underneath the raft to the upper surface, to control temperature and humidity of the plant. Additional embodiments include wireless sensors that may or may not be part of a raft, and a growing environment control system that can receive data from one or more sensors of environmental conditions of a plant and in other embodiments, can detect discrepancies between the actual environmental conditions and desired conditions. In still further embodiments, a growing environment control system can automatically adjust an actuator to return an environmental condition to a desired state.
