Each fluid bladders has an associated pressure sensing device which measures the pressure exerted by the user's foot on the fluid bladder. As the pressure increases over a threshold, a control system partially opens a fluid valve to allow fluid to escape from the fluid bladder. The release of fluid from the fluid bladders reduces the impact of the user's foot with the traveling surface. | InventorApplicationNo. 972450 filed on 11/18/1997US Classes:36/29, Pneumatic36/28, Cushion73/172, ORTHOPEDIC PRESSURE DISTRIBUTION600/592FootField of Search36/28, Cushion36/29, Pneumatic36/93, Form-fitting interior36/132, Attachment (e.g., weight for shoe, etc.)36/136, Shoe attachment (e.g., ornament, pocket, etc.)73/172, ORTHOPEDIC PRESSURE DISTRIBUTION600/592FootExaminersPrimary: Sewell, Paul T.Assistant: Stashick, Anthony Attorney, Agent or FirmUS Patent References3717039, 4121453, Foot force transducerIssued on: 10/24/1978 Inventor: Levin , et al.4267728, Apparatus for analyzing the forces acting on a human foot Issued on: 05/19/1981 Inventor: Manley , et al.4446634, Footwear having improved shock absorption Issued on: 05/08/1984 Inventor: Johnson , et al.4583305, Ski boot Issued on: 04/22/1986 Inventor: Miyamoto4745930, Force sensing insole for electro-goniometer Issued on: 05/24/1988 Inventor: Confer4814661, Systems for measurement and analysis of forces exerted during human locomotion Issued on: 03/21/1989 Inventor: Ratzlaff , et al.4827763, Pressure mapping system with capacitive measuring pad Issued on: 05/09/1989 Inventor: Bourland , et al.4862743, Device for measuring the areal distribution of compressive forces Issued on: 09/05/1989 Inventor: Seitz4876758, System and method for forming custom-made shoe inserts Issued on: 10/31/1989 Inventor: Rolloff, et al.4995173, High tech footwear Issued on: 02/26/1991 Inventor: Spier5033291, Flexible tactile sensor for measuring foot pressure distributions and for gaskets Issued on: 07/23/1991 Inventor: Podoloff, et al.5079949, Surface pressure distribution detecting element Issued on: 01/14/1992 Inventor: Tamori5083466, Multidimensional force sensor Issued on: 01/28/1992 Inventor: Holm-Kennedy, et al.5095762, Multidimensional force sensor Issued on: 03/17/1992 Inventor: Holm-Kennedy, et al.5107854, Orthopedic limb load monitor Issued on: 04/28/1992 Inventor: Knotts, et al.5179792, Shoe sole with randomly varying support pattern Issued on: 01/19/1993 Inventor: Brantingham5186062, Method of investigating the gait of a living being Issued on: 02/16/1993 Inventor: Roost5199191, Athletic shoe with inflatable mobile inner sole Issued on: 04/06/1993 Inventor: Moumdjian5230249, Shoe or boot provided with tank chambers Issued on: 07/27/1993 Inventor: Sasaki, et al.5253435, Pressure-adjustable shoe bladder assembly Issued on: 10/19/1993 Inventor: Auger, et al.5253656, Apparatus and method for monitoring contact pressure between body parts and contact surfaces Issued on: 10/19/1993 Inventor: Rincoe, et al.5257470, Shoe bladder system Issued on: 11/02/1993 Inventor: Auger, et al.5311779, Pressure-sensitive sensor Issued on: 05/17/1994 Inventor: Teruo5323650, System for continuously measuring forces applied to the foot Issued on: 06/28/1994 Inventor: Fullen, et al.5353525, Variable support shoe Issued on: 10/11/1994 Inventor: Grim5357696, Device for measuring force applied to a wearer's foot Issued on: 10/25/1994 Inventor: Gray, et al.5360016, Force transducer for a joint prosthesis Issued on: 11/01/1994 Inventor: Kovacevic5361778, Method and apparatus for sensing and evaluating foot borne motion Issued on: 11/08/1994 Inventor: Seitz5363570, Shoe sole with a cushioning fluid filled bladder and a clip holding the bladder and providing enhanced lateral and medial stability Issued on: 11/15/1994 Inventor: Allen, et al.5372487, Inlet check valve for pump mechanism Issued on: 12/13/1994 Inventor: Pekar5383290, Conformable shoe with vacuum formed sole Issued on: 01/24/1995 Inventor: Grim5408873Foot force sensor Issued on: 04/25/1995 Inventor: Schmidt, et al.
