- Dan Frey, Larry Carlson, and Vidya Ramaswamy developed several devices based on an interesting concept together, and published [http://www.oandp.org/jpo/library/1995_04_124.asp a paper] about the device. Despite the good idea, in which the adjusting button shown in the pictures below changes the angle of the tension band, allowing adjustment of the closing force, they were unable to get a patent because of the existence of a 1954 German patent (reference needed). - -	+ Dan Frey, Larry Carlson, and Vidya Ramaswamy developed several devices based on an interesting concept together, and published [http://www.oandp.org/jpo/library/1995_04_124.asp a paper] about the device.
