摘要： The press brake safety device includes a vertically movable guard for moving in advance of the press brake ram, a lightweight protector bar movably positioned on the lower edge of the guard for vertical upward movement and means operably connecting an actuation means for the ram to the ram drive means to control ram actuation. Air operated means connect to these ram drive means to render the same inoperable, and air operated control means connect the protector bar and the air operated means to actuate such last named means when the protector bar is moved upwardly in relation to the guard as the guard is being moved downwardly by actuation of the press brake for work engaging action.

摘要： A golf accessory for determining a gimme putt distance is disclosed. The golf accessory comprises a handle with a trigger, a telescoping rod mounted to the trigger including a length adjustment configuration, a hinge mechanism mounted to the telescoping rod and a base mounted to the hinge mechanism. The hinge mechanism is configured to allow the telescoping rod to fall horizontally on a ground surface upon activation of the trigger to determine a gimme distance in a golf game. The gimme is determined as positive if the telescoping rod covers a ball marker on the ground surface. The gimme is determined as negative if the telescoping rod fails to cover a ball marker on the ground surface.

摘要： A pulse active steering control system and method for use in a motor vehicle for improving vehicle stability by reducing a likelihood for rollover and/or skidding sends pulses to the steerable wheels whenever a rollover coefficient and/or the difference between the estimated and actual yaw rate is outside a predetermined range. The pulses are asymmetrical in the form of a smooth curve with a gradually increasing rapid rising edge and a slower falling edge and provide steering input that, along with the driver steering input, returns the rollover coefficient and/or yaw rate to the predetermined range to reduce the likelihood of rollover and/or skidding.
