Angelo Ferri has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Device for the precise measurement of magnitudes and method of verification of correct functioning of the device
    Patent number: 6323662
    Abstract: The improved device for precise measurement of magnitudes includes a closed network circuit, an instrument for detecting malfunctions in the closed network circuit and means for outputting an indication of the balance of the closed network circuit. The closed network circuit includes a power source; a transducer in the form of a Wheatstone bridge that is defined by paired series resistors and defines a branch of the closed network circuit and the transducer is serially connected to the power source; and a resistive branch connected in series to the Wheatstone bridge. The instrument is connected to a first connecting point in the resistive branch and to second and third connecting points on the Wheatstone bridge. The instrument calculates a sum of the potential differences between the second and third connecting points and the first connecting point and outputs the summed potential differences.
