  • Fully variable mechanical valve train in an internal combustion engine
    Patent number: 7765972
    Abstract: A variable mechanical valve train for actuating a valve in an internal combustion engine includes a two-part follower operatively coupled between a cam shaft and a valve, so that the follower: in a fully-activated mode, causes a maximum lift of the valve in response to a rotation of the cam shaft; in a partial load mode, collapses partially so as to cause a partial valve lift during the rotation of the cam shaft; and in a deactivated mode, collapses in response to the rotation of the cam resulting in no valve lift.

  • Two-stroke internal combustion engine with oil ring
    Patent number: 7735834
    Abstract: A two-stroke internal combustion engine having a seal assembly disposed between a piston and a running surface. The seal both lubricates and prevents exhaust of combustion gases. A first element, which ensures gas tightness, is received in a countersunk portion of the running surface. A second element, which ensures oil tightness, is partially embedded into the first element. A biasing element presses the second element against the first element so that the second and third elements are at least partially held within the first element.

  • Object detection using acoustic imaging
    Patent number: 7532541
    Abstract: Embodiments of the present invention include methods and apparatus for the detection of objects using acoustic imaging. Vibrational resonance characteristics of man-made objects may be significantly different from those of the surrounding natural materials, allowing an acoustic image to highlight the position of the object, even if the object is concealed from visual imaging.
