Abstract: An unmanned aircraft may be configured to avoid restricted areas by storing a database defining restricted areas in a memory of the aircraft and/or in a memory of a remote controller apparatus. Processor circuitry on the unmanned aircraft and/or in the remote controller apparatus receives an input command from to maneuver the unmanned aircraft. The input command may be a control input from a pilot, or a pre-programmed flight schedule command. Before performing the commanded maneuver, the processor circuitry predicts whether the maneuver is likely to violate a flight regulation, by entering a restricted area stored in the database, for example. If a violation is predicted, the command input command is ignored, discarded and/or blocked without executing the commanded maneuver.

Abstract: A hybrid light bulb is configured to automatically select a low heat emitting (low power) mode such as a CFL bulb portion when ambient temperature is above a predetermined threshold, and to select a high heat emitting (conventional incandescent or halogen bulb) portion when ambient temperature is below the predetermined threshold
