Patent number: 10512243Abstract: A system includes a cylinder and a piston that moves within the cylinder from a retracted position to an extended position. A vacuum port facilitates application of a vacuum pressure to the cylinder that results in a vacuum force being applied to the piston, which causes the piston to move toward a top end of the cylinder to the retracted position. A spring member applies a spring force to the piston when the piston is in the retracted position. The spring force offsets at least a portion of the vacuum force. A sensor generates a displacement signal in response to detecting movement of the piston from the retracted position toward the extended position. A control unit receives the displacement signal generated by the sensor and generates a valve control signal to be communicated to a valve located on a vacuum line connecting a vacuum source to the vacuum port.Type: GrantFiled: December 5, 2017Date of Patent: December 24, 2019Assignee: Technologies Holdings Corp.Inventors: Ejvind D. Hansen, Joergen Frederiksen

Patent number: 9888663Abstract: A method comprises receiving a displacement signal generated by a sensor, the displacement signal generated by the sensor in response to detecting movement of a piston from a retracted position in a cylinder toward an extended position in the cylinder. The method further comprises generating, in response to receiving the displacement signal, a valve control signal to be communicated to a valve located on a vacuum line connecting a vacuum source to a vacuum port of the cylinder. The valve control signal causes the valve to move from a first position in which a vacuum pressure is applied to the cylinder via the vacuum port to a second position in which atmospheric pressure is applied to the cylinder via the vacuum port.Type: GrantFiled: May 24, 2017Date of Patent: February 13, 2018Assignee: Technologies Holdings Corp.Inventors: Ejvind D.

Patent number: 8944005Abstract: In certain embodiments, a system includes a cylinder and a piston, the piston positioned within the cylinder and operable to move within the cylinder from a retracted position to an extended position. The system further includes a vacuum port facilitating application of a vacuum pressure to the cylinder, the vacuum pressure resulting in a vacuum force being applied to the piston, the vacuum force causing the piston to move toward the retracted position. The system further includes a spring member configured to apply a spring force to the piston when the piston is in the retracted position, the spring force offsetting at least a portion of the vacuum force. The system further includes a sensor operable to generate a displacement signal in response to detecting movement of the piston from the retracted position toward the extended position.Type: GrantFiled: June 7, 2011Date of Patent: February 3, 2015Assignee: Technologies Holdings Corp.Inventors: Ejvind Hansen, Joergen Frederiksen
