Patent number: 9341092Abstract: An exhaust valve assembly for a two-stroke internal combustion engine has a valve actuator having a first pressure chamber and a second pressure chamber, and a valve operatively connected to the valve actuator. The first and second pressure chambers are adapted for selectively receiving one of a first pressure and a second pressure. The first pressure is higher than the second pressure. The valve actuator moves the valve between at least a first valve position and a second valve position.

Patent number: 8467269Abstract: Advantageous online and/or real-time OFDM-based underwater acoustic (UWA) apparatus, systems and methods are provided according to the present disclosure. The apparatus, systems and methods employ a receiver with a bank of parallel branches, with each branch having a self-correlator matched to a different waveform scaling factor. A detection is declared when any of the branches leads to a correlation metric larger than a pre-defined threshold. The branch with the largest metric yields a Doppler scale estimate and a coarse synchronization point. The proposed apparatus, systems and methods use one OFDM preamble, thereby avoiding the need to buffer the whole data packet before data demodulation and enabling online and/or real-time operation. Thus, the disclosed apparatus, systems and methods are advantageously applicable to UWA communications.Type: GrantFiled: April 1, 2010Date of Patent: June 18, 2013Assignee: University of ConnecticutInventors: Shengli Zhou, Peter Willett, Christian Berger, Sean Mason

Patent number: 8375902Abstract: A poppet valve has a valve head and a valve stem. A piston is capable of reciprocating motion relative to a housing along a reciprocation axis. The piston has a valve-receiving portion for receiving therein an end portion of the valve stem. A cotter secures the valve stem to the piston. A cap is disposed around the valve-receiving portion. A cap lateral portion extends away from the cap end portion in the direction of the valve head. The valve-receiving portion is held between the cap end portion and the cap lateral portion in a direction parallel to the reciprocation axis. At least part of the cap lateral portion is angled toward the reciprocation axis. The part of the cap lateral portion is closer to the reciprocation axis than at least part of the valve-receiving portion. A method of assembling a valve assembly is also described.Type: GrantFiled: January 20, 2010Date of Patent: February 19, 2013Assignee: BRP-Powertrain GmbH & Co.
