Patent number: 10557394Abstract: A heat recovery device extends between an inlet and an outlet for exhaust gas, and includes a valve delimiting a direct passage for gas between the inlet and the outlet. The valve comprises a valve body housing a gate movable between a closing off position and a released position. A heat exchanger has an exchanger inlet upstream of the gate and an exchanger outlet downstream of the gate. The valve comprises a tube partially extending inside the valve body up to a mouth edge at a distal end, with the mouth edge extending in a plane. The gate has a plane contact surface configured to come in a direct contact with the mouth edge when the gate is in the closing off position.Type: GrantFiled: February 27, 2017Date of Patent: February 11, 2020Assignee: Faurecia Systemes D'EchappementInventors: Frederic Greber, Yong-Hwan Oh

Patent number: 8126594Abstract: The present invention may provide a method of generating a walking pattern for a humanoid robot. The method of generating the walking pattern for the humanoid includes determining a position of a next Zero Moment Point (ZMP) along a moving direction of the humanoid robot, obtaining a first condition for generating a walking pattern based on the determined ZMP by using a periodic step module, generating trajectories of a ZMP and a Center of Mass (CoM) in an initial step based on the first condition and an initial value obtained from an initial state of the humanoid robot by using a transient step module, generating trajectories of a ZMP and a CoM in a steady step based on the ZMP of two steps by using a steady step module, and generating trajectories of a ZMP and a CoM in a final step by using the transient step module.Type: GrantFiled: October 29, 2008Date of Patent: February 28, 2012Assignee: Korea Institute of Science and TechnologyInventors: Seok Min Hong, Yong Hwan Oh, Young Hwan Chang, Do Ik Kim, Bum Jae You
