Abstract: A dual air vent allows air or gas to be vented from a wet pipe fire protection sprinkler system, but inhibits water from spilling out. A conventional first air vent valve is operative to vent air or gas as a pipe is filled with water, but not vent the water. However, it may discharge a small amount of water when the pipe fills and substantially all air or gas has been vented. The output of the first air vent valve is not released into the protected premises, but rather is routed to a reservoir having a second air vent. Air or gas is vented through the second air vent, but any water discharged by the first air vent valve is retained in the reservoir. The reservoir is connected to the pipe by a one-way valve which allows air flow in either direction, and allows water flow from the reservoir to the pipe, but blocks water flow from the pipe to the reservoir. When the pipe is again drained, water retained in the reservoir is allowed to flow into the pipe, where it is also drained.

Abstract: Techniques are described for implementing adaptive coding and modulation (ACM) in regenerative satellite systems to adapt the modulation and/or FEC coding of transmitted waveforms to the conditions of the link. In a first implementation, ACM is implemented on an uplink from a terminal to a regenerative satellite. In this implementation, an uplink modulation and coding combination (ModCod) is estimated by the transmitting terminal based on the quality of signals received from the regenerative satellite on the downlink. In a second implementation, ACM may be implemented on a downlink from a regenerative satellite to a terminal. In this implementation, a transmit terminal may insert a field in a transmitted packet header that indicates a downlink ModCod to be used by the regenerative satellite when transmitting packets to a receiving terminal. The regenerative satellite may reencode and remodulate the packet using the ModCod indicated in the field of the packet header.
