Abstract: The present invention is a thermal detection device for a reversing vehicle. The thermal detection device for a reversing vehicle warns driver of any warm bodied obstruction such as a person or an animal. The present invention utilizes digital pryoelectric sensors as means to detect a warm bodied obstruction. The digital pryoelectric sensors are compact and accurate and are sensitive to a warm bodied object at a relatively far distance. The present invention geometrically positions the digital pryoelectric sensors so that the present invention can detect a warm bodied obstruction with almost a 180° field of vision behind the vehicle. The present invention notifies the driver of a warm bodied obstruction entering the vehicle's reverse path with both a visual and an aural warning.

Abstract: A pick-and-place tool releasably retains a part during a pick-and-place operation by an automated device. The pick-and-place tool includes a front structure having a first bore disposed therein for receiving a shaft extending from the part. A plurality of locking mechanisms is disposed within the front structure. The plurality of locking mechanisms are evenly spaced around the inner surface and are in fluid communication with a common fluid source. Each locking mechanism in the plurality of locking mechanisms includes a bearing disposed proximate an aperture in the inner surface, and a piston in mechanical communication with the bearing. Movement of the piston in response to a fluid pressure at the common fluid source forces the bearing to extend through the aperture and retain the shaft within the first bore. In one aspect, a resilient member is disposed between the front structure and a tool holder coupled to the automated device.

Abstract: A telescoping column includes a first tube and a second tube arranged in telescoping fashion. A locking structure is disposed between a surface formed on the first tube and a ramp disposed on the second tube. The locking structure contacts the ramp at a first elongated area of contact, and the locking structure contacts the surface at a second elongated area of contact. Relative movement of the first and second tubes in response to an impact force applied to one of the first and second tubes causes the locking structure to become wedged between the ramp and the surface, and at least a portion of the impact force between the first and second tubes is transmitted through the first and second elongated areas of contact.

Abstract: A reconfigurable fixture for workpieces is disclosed. It utilizes a flat surface magnetic chuck with modular workpiece supporting, locating and clamping elements that are carefully located on it and held by magnetic attraction to it. These elements are precisely located to hold the workpiece in spaced relation to the chuck surface. Some locating elements are mechanically fixed to the chuck for securing the workpiece from transverse movement on the chuck surface. Preferably, each of the supporting, locating and clamping members are fixed to separate steel bases for magnetic attraction to the chuck. Each base may also carry its own hydraulic actuator for height adjustment of a support element or for height adjustment and closure of a clamping element. These modular elements have locating slots or grooves or the like so that they can be selected from a storage magazine and located on a chuck by numerically controlled mechanisms.

Abstract: A beam system of telescoping tubes is used for absorbing side impacts to a passenger vehicle. A central outer tube is attached to a vehicle seat structure and extends between, e.g., a side door and the tunnel in the passenger compartment floor. Inner tubes in each end of the outer tube are moved between retracted positions to extended positions respectively engaging said tunnel and said door during vehicle operation. Each inner tube has a tapered piston carrying rolling elements for wedging against the outer tube for energy absorption upon a side impact.

Abstract: An adapter for picking up and placing a fixture element on a fixture body using a controlled tool handling device having a tool translating and rotating spindle. The spindle has a tool receiving end and an axis of rotation. The adapter receives a cylindrical post member of a fixture element on a fixture body. The adapter has a first end having a receptacle for receiving the end of the spindle. The second end of the adapter is displaced from the first end and includes a cylindrical socket formed on the end. The socket is co-axial with the spindle and receives the cylindrical post member of the fixture element. A fluid passage is formed in the adapter from the receptacle to the cylindrical socket. The cylindrical socket has an upstream end and a down stream end. A piston is disposed in the upstream end of the socket. The piston is moveable longitudinally within the socket in response to fluid pressure delivered from the spindle through the fluid passage.

Abstract: An extendible bumper system for a vehicle includes a controller system configured to: determine a distance of travel of a first end of a bumper structure using a signal from a position sensor in a first motor, determine a distance of travel of a second end of the bumper structure using a signal from a position sensor in a second motor, and independently adjust at least one of rotational speed and torque output of rotors in the first and second motors in response to the distances of travel. The rotational speed or torque output of the first and second rotors may be independently adjusted in response to a difference in the distances of travel of the first and second ends of the bumper structure, and the rotational speed or torque output of the first and second rotors may be accelerated or decelerated during predetermined distances of travel. A bumper energy absorber for supporting the bumper structure relative to a vehicle includes an inner tube, outer tube, lead screw, nut and motor.

Abstract: A knee bolster system is capable of automatic extension and retraction during specified scenarios that are determined based on sensor input. A microprocessor electrically controls an actuator capable of extending at least one telescoping mechanism which is rigidly engaged to a knee bolster pad located in the lower portion of an instrument panel at knee height to an occupant. Each telescoping mechanism houses a plowing mechanism. This plowing mechanism generates reaction forces during actuation.

Abstract: A self-locking telescoping device including an outer tube, an inner tube telescoped into the outer tube having a cone-shaped ramp at an inboard end, and a plurality of metal spheres between the ramp and the outer tube. The metal spheres wedge between the ramp and the outer tube when the inner tube is thrust into the outer tube in a collapse direction thereby locking the tubes together. When the thrust is attributable to a severe impact, the spheres plastically deform the outer tube by plowing tracks therein thereby to absorb energy. The self-locking telescoping device further includes an actuator rod, a driver which translates the actuator in the collapse direction and in an expansion direction, a first clutch which translates the inner tube with the actuator rod in the expansion direction, a second clutch which translates the inner tube with the actuator rod in the collapse direction, and a tubular retainer on the actuator rod having a plurality of closed-ended slots around the metal spheres.
