Latest Patents

One of his latest patents is a fluid flow measuring apparatus. This Karman vortex type flow rate measuring apparatus is equipped with multiple vortex shedding members, each having a different effective width. It also includes several vortex detecting elements. The design ensures that the distance between the vortex detecting elements coincides with the distance between the vortices of a specific vortex train induced by the respective vortex shedding members. This innovation allows for accurate detection of vortices and compensates for any dropout of the vortex shedding.

Another significant patent is a circuit for generating pulses with a duration proportional to the quotient of two input voltages. In this design, first and second transistors are connected in a monostable multivibrator configuration. A capacitor is coupled between the collector of the first transistor and the base of the second transistor. The circuit is designed to generate a control pulse for each revolution of an engine's output shaft, with the width of the output pulse being proportional to the first input voltage and inversely proportional to the second input voltage.
