20130139605 | Means to Track the Cumulative Compressions Imparted to a Shoe - A device, inserted in a running shoe is used to track the accumulation of destructive compression cycles within the shoe and to indicate this information to the user through a series of integrated indicators. The device has an advantage of being able to be placed in any shoe without compromising the construction or performance of the shoe. An additional advantage of the invention is the improved accuracy of the information by improving both the stability and longevity of the sensor system and the ability to distinguish destructive, partially destructive and nondestructive compressions. Another advantage of the invention is the reduction of the cost of construction while achieving a lifetime in excess of the shoe. Yet another advantage of the invention is the user interface, which is contained completely within the device allowing the user to view the information within the shoe. | 06-06-2013 |
20160163959 | COMPOSITE MATERIAL USED AS A STRAIN GAUGE - In one general aspect, an apparatus comprises a material including a non-layered mixture of an elastomeric polymer with a plurality of voids; and a plurality of conductive fillers disposed in the elastomeric polymer. The apparatus may produce an electrical response to deformation and, thus, function as a strain gauge. The conductive fillers may include conductive nanoparticles and/or conductive stabilizers. In another general aspect, a method of measuring compression strain includes detecting, along a first axis, an electrical response generated in response to an impact to a uniform composite material that includes conductive fillers and voids disposed throughout an elastomeric polymer, and determining a deformation of the impact based on the electrical response. The impact may be along a second axis different from the first axis. | 06-09-2016 |
