Patent number: 10942540Abstract: An output signal device and method that provides the operator force feedback similar to a pilot control joystick. These force feedback regions include free play, dead-band start of modulation, modulation, fore-warning bumper and hold near max angle. This output signal device may also vary the fore-warning feel and hold positions to be at any angle. This output signal device uses force sensing as the signal and has force slope changes used as auto-calibration of the output signal. This improves signal accuracy and provides a service prognostic signal. The prognostic signal may be used to activate redundant sensor. The variable force feedback may improve operation on rough terrain. The force feedback, may allow more productive operating positions to be learned. This enables productivity and other important job site criteria such as fuel usage to be optimized by interactive communication with this output signal device.Type: GrantFiled: November 17, 2017Date of Patent: March 9, 2021Assignee: Prince Industries, Inc.Inventors: David Paul Smith, Chun Feng Xia, Lukasz Grzegorz Osikowicz

Patent number: 10648575Abstract: A hydraulic valve is provided that includes an interior spool and a surrounding cage. A supply port and a return port are connected to the cage and the interior of the cage is in fluid communication with a control port. The interior spool is positioned between an on and off position using a solenoid and a spring. In the off position, slots in the spool and cage align to place the return port in fluid communication with the interior of the spool. Conversely, in the on position, different slots in the spool and cage align to place the supply port in fluid communication with the interior of the spool.Type: GrantFiled: October 24, 2013Date of Patent: May 12, 2020Assignee: PRINCE INDUSTRIES, INC.Inventor: David Paul Smith

Patent number: 10073487Abstract: A system and method is provided for an adjustable spring plunger bumper with high initial load and low final load. The spring plunger bumper includes an exterior body surrounding a plunger. The plunger has a plunger indent into which a displacement ball is induced by a ramp sleeve biased by a ramp sleeve spring. As the plunger is displaced relative to the exterior body, the displacement ball contacts a lower displacement ball inclined surface, which provides a high initial load resisting the displacement of the plunger. However, as the displacement of the plunger continues, the displacement ball comes into contact with a smooth lower displacement ball indent surface which provides a lower load. A return spring is positioned between the plunger and the exterior body to return them to their initial position relative to each other when the displacement of the plunger is removed.Type: GrantFiled: December 21, 2015Date of Patent: September 11, 2018Assignee: Prince Industries, Inc.Inventors: David Paul Smith, Kevin Alan Brown
