  • Publication number: 20190218997
    Abstract: Provided is a piston for an internal combustion engine. The piston includes a body including, at an upper part of the body, a crown including a combustion chamber where fuel is burnt and including, at a lower part of the body, a piston pin boss into which a piston pin is inserted and a skirt corresponding to a cylinder wall, and a cooling channel including a refrigerant channel, a refrigerant inlet provided at a side of the refrigerant channel, and a refrigerant outlet provided at the other side of the refrigerant channel, wherein a cross section of the cooling channel has an overall elliptic shape to reduce stress occurring at an upper side of the cooling channel when the fuel is burnt in the internal combustion engine, and at least one of arcs of the ellipse is configured as a first elliptical arc of a quadratic curve.

  • Publication number: 20170333724
    Abstract: A bio-stimulation robot includes a stationary platform, a plurality of drive modules coupled to the stationary platform, and a motion platform coupled to the drive modules to operate to change a position of the motion platform. Each of the drive modules includes a first guide member having an arc shape, a motion member coupled to the first guide, and a leg member having a first end coupled to the motion member and a second end fixed to the motion platform. The motion member slides along the first guide member. The second end of the leg member is rotatably connected to the motion platform. The second end of the leg member is rotatably connected to the motion platform.

  • Patent number: 9129144
    Abstract: Disclosed is radio frequency identification (RFID) middleware system and method of detecting the load of reader connections occurs during the middleware is running and balancing the load in real-time so as to minimize a decrease of the performance of the RFID middleware system. The RFID middleware system comprises: a client; a RFID middleware; RFID readers; and RFID tags, wherein the RFID middleware comprises: a middleware engine which filters tag events collected according to queries registered in the client; and a reader framework which detects the load of the connections of the RFID readers occurs while the RFID middleware is running and balances the load in real-time.
