| 20090095050 | ELECTRONIC SHOE WEAR INDICATOR - A system measures an amount of wear in athletic footwear by measuring the amount of shock transmitted to a user. The measured shock is used to indicate an amount of how much cushioning has been lost by the footwear. The amount of wear is proportional to the loss of cushioning and an increase in transmitted shock to the user. | 04-16-2009 |
| 20120247177 | METHOD FOR MEASURING MECHANICAL POWER DISSIPATION IN A VIBRATORY SYSTEM - A method for determining mechanical power dissipation in a vibratory system, assuming the system is linear time-invariant and steady-state. The method includes the steps of identifying connection points between the vibratory system and components outside the vibratory system. The acceleration is measured at each connection point in a windowed time domain and the force at each connection point is also determined for the windowed time domain. The time domain values are converted into the frequency domain values by the fast Fourier transform, and the frequency domain acceleration values are converted to velocity values. The power dissipation of the vibratory system then equals the summation of one half of the power flow into the vibratory system. Here, each power flow is one half of the real part of the product of complex-conjugated velocity times force at the connection point in the frequency domain for each time window. | 10-04-2012 |
| 20130061651 | SHIM STACK TESTING APPARATUS AND METHOD - A shim stack testing apparatus and method of determining a stiffness of the shim stick may be employed to assemble a shim stack kit. The apparatus includes a testing jig that receives either a compression or rebound shim stack. The testing jig may be used with a variety of testing machines capable of determining force versus deflection. The test jig includes a simulated piston rod coupled to a simulated piston valve having apertures. The shim stack being tested may be coupled to the piston at a selected location and then deflected by a pre-determined amount by a loading fixture having elongated prongs. Once the pre-determined deflection is achieved, a corresponding force is identified and then an overall stiffness value for the shim stack is obtained. Tested shim stacks may be assembled into kits with each having an identified stiffness that may be compared to a baseline stiffness value. | 03-14-2013 |
