  • Belt monitoring systems and methods
    Patent number: 8312987
    Abstract: A belt monitoring system employs a belt having at least one reinforcement member made from a conductive reinforcement material. A belt monitor is disposed in conjunction with the belt. The belt monitor comprises a field inductor excited by an applied signal. An electrical characteristic of at least a portion of the field inductor as influenced by changes in the electrical properties of the conductive reinforcement member is monitored in order to determine a physical condition of the conductive reinforcement member and thereby monitor a physical characteristic of the belt. This monitoring may be carried out by a sense inductor disposed adjacent or in conjunction with the field inductor.

  • Accessory and motor/generator belt drive tensioner
    Publication number: 20020039944
    Abstract: The invention is an improved belt tensioner for a belt drive system having a belt tensioner, a crankshaft pulley, an accessory pulley, and a motor/generator pulley. The belt drive system further includes a power transmission belt trained about the crankshaft pulley, the accessory pulley, and the motor/generator pulley. The belt tensioner is of the type including an attachment point adapted to be affixed to a stationary point relative to a cylinder block of an engine, a first belt tensioner pulley, a biasing member, and a connective portion adapted to communicate a force from the biasing member to the power transmission belt via the first belt tensioner pulley.
