  • Ground effect vehicle
    Patent number: 6230835
    Abstract: The invention concerns a ground effect vehicle comprising hydrofoils or hydrofoil outer parts (18) which can pivot about a parallel line relative to the longitudinal axis of the body in order to increase the speed range when flying close the ground. In addition, the hydrofoils and the body can be provided with trailing edge flaps (19) which are articulated so as to pivot about a horizontal axis and, depending on the selected angle of incidence of the hydrofoils or hydrofoil parts, can be controlled as lift-increasing ailerons or flippers.

  • Measuring the miss distance of projectiles
    Patent number: 5072428
    Abstract: The miss distance of a projectile aimed towards a target is determined by a line of pressure transducers other than microphones which through response to a sudden pressure change together establish a cone section through a passing Mach cone; and the time space analogies of that cone permits reconstruction of the projectile path being in effect the axis of that cone.

  • Process and device for measuring the tension of racket strings
    Patent number: 5007294
    Abstract: A method and device for measuring the string tension of a strung racket such as a tennis racket wherein a mechanical/electrical transmitter is attached to the membrane made from the racket strings mounted crosswise onto a frame and measures the frequency of the membrane. The membrane is induced to freely oscillate in an aperiodically (non-periodically) manner by a light stroke onto the frame or by dropping a ball onto the membrane. The measured frequency is proportional to the string tension which is indicated by a display.
