Patent number: 7353770Abstract: A visual wear indicator is disclosed capable of giving a visual indication of the degree of wear on an athletic or other type of shoe. In general, the visual wear indicator may operate by having two different colored regions, each having a viscosity which varies a function of pressure. Before pressure is applied, the boundary between the two regions is clear. However, over time, as the midsole and/or outer sole of the shoe wear away, the pressure exerted on the visual wear indicator increases during activity. As the pressure increases, the viscosity of the regions eventually decreases. When the viscosity decreases, the regions bleed together, and the boundary between the regions becomes less clear. The degree of mixture between the regions may be calibrated to give a clear visual indication of when the shoe has worn down to the point where the shoe is unable to provide a desired level of support and stress absorption.Type: GrantFiled: December 6, 2005Date of Patent: April 8, 2008Inventor: Chéri Sanguinetti

Patent number: 6943672Abstract: The warning apparatus includes magnetic force generating units, each oppositely arranged about a timing belt to generate a mutually opposite polarity of a magnetic force. A voltage inducing unit is disposed at one lateral surface of the timing belt to induce a voltage in response to the magnetic force generated from the magnetic force generating units. A voltage detecting unit detects the voltage induced by the voltage inducing unit. A controller outputs a control signal for generating a warning signal when the voltage detected by the voltage detecting means is less than an established level. A warning generating unit generates an alarm that a replacement time of a timing belt has arrived in response to the control signal from the controller, such that when a timing belt is worn to a degree of breakage, a warning signal is given by a detection thereof so that a healthy timing belt should not be changed periodically.Type: GrantFiled: December 30, 2003Date of Patent: September 13, 2005Assignee: Hyundai Motor CompanyInventor: Young-Ho Choi
