Abstract: A tonneau cover system for a vehicle includes a cover, a scissor lift assembly, and an electric actuator. The scissor lift has a fixed arm for mounting to an inner side panel of a cargo bed of the vehicle and a plurality of movable arms coupled to the fixed arm for selectively raising and lowering the cover in dependence upon a distance between a drive point on one of the movable arms and the fixed arm. The electric actuator has an end anchored at a fixed position relative to the fixed arm and a second end coupled to the drive point. The actuator dynamically changes length under electrical power to be between an extended length and a retracted length thereby changing the distance between the drive point and the fixed arm. A controller control the electric actuator to change length in accordance with a user input signal.

Abstract: An actuator and an assembly utilizing two or more actuators for vertically actuating a cover for a spa. In the lowered position the cover protects the spa and in the elevated position the cover acts as a roof over the spa. The actuator is either a rack and pinion assisted by a cable and pulley or a chain and a plurality of sprockets assisted by a cable and pulley which are connected to lift member which are generally shrouded by telescoping tubes to cover the actuators or to act as lift members themselves. The system can be further enhanced using a gas spring to assist in lifting the cover and reduce the load of the cover weight off the motor which is used to actuate the actuators.

Abstract: A training device for a putting stroke in the game of golf. A base and sidewalls form a track which defines the path of the stroke. A guide attached to the putter head fits within the track and prevents the putter head from binding in the track and thus directs the putter head along the track causing the golfer to keep proper wrist alignment and to build muscle memory when properly stroking the ball. One version of the track permits the width of the track to be adjusted to accommodate putters having different sized heads. Further, a portion of the track may be adjusted to train a putting stoke having a slightly curved backswing.
