Patent number: 8038366Abstract: A wheeled concrete screeding device includes a wheeled unit having wheels for movably supporting a frame portion, and a screed head supported at the frame portion and following behind the wheeled unit when the wheeled unit is moved in a screeding direction. The screed head includes a grade establishing element and a vibratable member. The grade establishing element is generally vertically adjustable responsive to a signal from a laser receiver disposed at the screed head to establish a struck-off surface of the uncured concrete at a desired grade. The vibratable member is adjustably attached at the grade establishing element and the vibratable member at least partially floats behind the grade establishing element on the struck-off surface of the uncured concrete and is at least partially supported at the struck-off surface of the uncured concrete as the wheeled unit is moved in the screeding direction.Type: GrantFiled: November 22, 2010Date of Patent: October 18, 2011Assignee: Somero Enterprises, Inc.Inventors: Philip D. Halonen, Russ E. Stein, Mark A. Pietila, Michael R. Keranen, Carl B. Kieranen

Patent number: 7854565Abstract: A method of establishing a desired grade of an uncured concrete surface or subgrade surface includes providing a wheeled apparatus having a wheeled support and a plow assembly, which may include a plow member for establishing the desired grade and/or a vibrating member for vibrating and smoothing the concrete. The down pressure of the plow assembly may be adjusted when the wheeled support is moved in a rearward direction. The elevation of the plow member may be controlled when a direction signal is indicative of the wheeled support stopping and/or moving in the forward direction. The rearward speed of the wheeled support may be reduced in response to a detection of a surface irregularity of the subgrade, and the frame portion and/or the plow assembly may be controlled to substantially maintain the plow assembly at a desired orientation when the wheel engages the detected surface irregularity.Type: GrantFiled: August 5, 2008Date of Patent: December 21, 2010Assignee: Somero Enterprises, Inc.Inventors: Philip D. Halonen, Russ E. Stein, Mark A. Pietila, Michael R. Keranen, Carl B. Kieranen

Patent number: 7407339Abstract: A wheeled strike-off apparatus is movable over a surface of uncured concrete or subgrade materials and is operable to establish a desired grade of the uncured concrete surface or subgrade surface. The apparatus includes a wheeled support and a plow assembly. The plow assembly may be adjustably mounted to a front frame portion and may be vertically adjustable relative to the frame portion. The plow assembly may include a plow member for engaging and establishing the desired grade and/or may include a vibrating member for vibrating and smoothing the concrete after the plow member establishes the desired grade. The apparatus may include a user input that is adjustable by an operator to adjust a down pressure of the plow assembly at the concrete when the wheeled support is moved in a rearward direction.Type: GrantFiled: February 13, 2007Date of Patent: August 5, 2008Assignee: Somero Enterprises, Inc.Inventors: Philip D.

Patent number: 7195423Abstract: A wheeled strike-off apparatus is movable over a surface of uncured concrete or subgrade materials and is operable to establish a desired grade of the uncured concrete surface or subgrade surface. The apparatus includes a wheeled support and a plow assembly. The wheeled support may have a front frame portion and a pair of front wheels rotatably mounted at the front frame portion, and may have a rear frame portion and a pair of rear wheels rotatably mounted at the rear frame portion. The plow assembly may be adjustably mounted to the front frame portion and may be vertically adjustable relative to the frame portion via an actuator. The plow assembly includes at least one plow member for engaging and establishing the desired grade.Type: GrantFiled: July 26, 2005Date of Patent: March 27, 2007Assignee: Somero Enterprises, Inc.Inventors: Philip D Halonen, Russ E Stein, Mark A Pietila, Michael R Keranen, Carl B Kieranen

Patent number: 7125045Abstract: A system for reducing the forward motion of a vehicle occupant is provided. The system includes a contact surface, a fixed energy absorption device, a deployable energy device, and an energy absorption modifier. The contact surface interacts with a vehicle occupant. The fixed energy absorption device is attached to a structural member of the vehicle. The deployable energy device is in contact with the contact surface and the fixed energy absorption device. The energy absorption modifier is in communication with the fixed energy absorption device for varying the energy absorption characteristics of the fixed energy absorption device.Type: GrantFiled: November 26, 2003Date of Patent: October 24, 2006Assignee: Visteon Global Technologies, Inc.Inventors: Stephen E. Fuks, Michael R. Keranen
