Patents by Inventor John P. Fitzsimmons

John P. Fitzsimmons 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).

  • Patent number: 11946785
    Abstract: A material independent mass flow sensor is used to generate signals that can be used to calculate mass flow of grain harvested by a combine. A method for determining a mass of material includes the steps of receiving data from a three-measurement transducer and determining an angular center of mass location of an object based on the data from the three-measurement transducer. A coefficient of friction of the object is determined. A velocity of the object is determined. A mass of the object is determined. The mass of the object can be determined based on the angular center of mass location of the object, the coefficient of friction of the object, and the velocity of the object.
    Type: Grant

  • Patent number: 10041574
    Abstract: A linear powered input device that utilizes linear input from a user and converts the linear input to rotational energy to perform work. The linear input is generated by lever arms having a slotted attachment at a pivot point that allows a free end of the lever arms to move linearly rather than in an arcuate path. The lever arms are connected to a power transmission mechanism that wraps around one or more drive wheels having one-way bearings mounted on one or more output shafts. The output shafts can be connected to any type of auxiliary device to perform the desired work. Output wheels may be mounted on the output shafts and operatively connected by a transmission link that allows linear motion of any lever arm in any allowable direction to cause the output shaft to rotate in the same rotational direction so as to receive continuous input and/or generate continuous output.
