Abstract: An exhaust nozzle assembly provides fluidic thrust vectoring of the primary stream to enhance aircraft maneuverability. The exhaust nozzle assembly includes a cooling air passage that supplies cooling air. A vector opening injects cooling airflow into the exhaust passage to the primary stream. A cover plate is movable to partially block the vector openings and adjust the location of injection of the cooling airflow into the exhaust passage.

Abstract: A Universal Serial Bus to parallel bus bridge includes a Universal Serial Bus port that receives a serial bit stream of data and commands in a Universal Serial Bus protocol from a USB host computer. A parallel bus port on the bridge includes parallel port registers and state machines coupled to a peripheral device. A USB controller core is coupled between the Universal Serial Bus port and the parallel bus port and converts data and commands between the Universal Serial Bus protocol and the parallel bus protocol. A sequencer is coupled between the USB controller core and the parallel bus port. A sequence of sequencer commands is loaded into memory in the USB bridge and used by the sequencer to perform a sequence of parallel port operations. The sequencer performs the commands autonomously without intervention from the USB host computer.

Abstract: A Universal Serial Bus (USB) peripheral bridge and method for operation are disclosed. The bridge simulates a device disconnect condition to its upstream USB hub or host, even though it remains connected and powered, when its associated peripheral is not ready to communicate, powered off, or physically disconnected. For an IEEE-1284-1994 peripheral connection, the bridge senses the condition of the PLH peripheral line. If the PLH line is deasserted or floating, the bridge simulates a device disconnect condition by either allowing its upstream hub or host to take the D+ data line low, or taking the line low itself. By not allowing itself to be enumerated on the USB unless its associated peripheral is ready, the bridge avoids confusion at the host and wasted bus resources. At the same time, the bridge may remain physically connected to the host regardless of the state of the peripheral, even if the bridge is powered from the host.
