  • Threshold setting for a radar level transmitter
    Patent number: 7542866
    Abstract: Disclosed is a method and apparatus for setting threshold values for use by a radar level transmitter to detect reflected wave pulses corresponding to portions of a transmitted microwave pulse which reflect from interfaces contained in a container. The present invention estimates these threshold values based upon various parameters. Some of these parameters can relate to properties of the materials forming the interfaces while others relate to properties of the antenna and user-defined parameters.

  • Hydromechanical transmission electronic control system for high speed vehicles
    Patent number: 6942596
    Abstract: An electronic transmission control system that can achieve a transmission ratio based on the operator inputs and the current vehicle operating conditions. The transmission constantly connects the engine to the load, and the transmission ratio is only varied by a change in command from the present invention. The transmission's mechanical function is solely to vary the ratio between its input and output. In using the present invention, an operator must select an operating mode, either automatic or manual, using a two-position switch. While in the automatic mode, the present invention determines the vehicle speed by considering the position of the throttle and the operator's use of brakes. In the manual mode, the present invention further considers the operator's selection of a gear condition.
