  • Patent number: 7040153
    Abstract: A memory tire pressure gauge apparatus for use with race cars, comprising a pressure transducer, a control system and a display. The pressure transducer is for communicative connection to a tire of a race car. The control system is communicatively connected to the pressure transducer, receives tire pressure reading signals from the pressure transducer, and converts them to tire pressure display signals The control system has memory for storing a plurality of tire pressure reading signals. The display is communicatively connected to the control system, It indicates at least eight tire pressure readings simultaneously, the eight tire pressure readings corresponding to a relatively cold tire pressure reading with respect to an initial time and a relatively hot tire pressure reading with respect to a later time, after use of the tires, for each of four tires. The display further shows, simultaneously, four tire pressure change readings corresponding to changes caused by the use of each of the tires.

  • Patent number: 6397657
    Abstract: An apparatus for testing torsion bars, comprising a frame, a load cell, a connector, a torque arm and a force applicator. The frame includes a torque end support positioned a predetermined distances from a load cell end support. The load cell is attached to the load cell end support, and the connector is rotatably attached to the torque end support. A torsion bar is connected to and extends between the load cell and the connector. The torque arm has a proximal portion attached to the connector, and at least one distal portion. The force applicator is attached to the distal portion of the torque arm and to the frame. The force applicator rotates the torque arm and provides a torque force to the torsion bar.

  • Publication number: 20010013766
    Abstract: A pyrotechnic self-consuming battery for emergency booster battery applications. Such a system can only be used once as the battery self-destructs but could be very useful for emergency starting of cars, trucks or airplanes. This invention allows for a system weighing approximately {fraction (1/50)}th that of existing systems with comparable significant reductions in volume. An essentially infinite shelf life also obtains with the invention. Systems are taught for emergency lighting and backup power generation.

  • Patent number: 6269688
    Abstract: A tire test apparatus, comprising a base, a support, a force applicator, a tire contact member in contact with a tire, a travel indicator mechanism, and a force indicator mechanism. The support extends upwardly from the base and holds a tire a predetermined distance above the base. The force applicator applies a force to cause pressure between the tire and the tire contact member. The travel indicator mechanism quantifies a change in relative positions between the tire and the tire contact member. The force indicator mechanism quantifies the force applied by the force applicator.

  • Patent number: 6047594
    Abstract: A digital turn plate apparatus for aligning steering systems of wheeled devices. The turn plate apparatus has a rotational degree of motion for determining the angle of wheel alignment. The turn plate apparatus also has lateral and longitudinal degrees of motion to accommodate the lateral and longitudinal motion of the bottom of tires which can occur during turning or when the suspension is compressed. The turn plate apparatus generally includes a base, a top plate, a handle plate, a lower middle plate, a potentiometer, and a digital display mechanism. The top plate is rotatably mounted to the handle plate and is functionally engaged with the potentiometer. The turn plate apparatus digitally displays the rotational position of the top plate to within a tenth of a degree. The handle plate is constructed to have a longitudinal degree of motion with respect to the base and the lower middle plate is constructed to have a lateral degree of motion with respect to the base.

  • Patent number: 5792190
    Abstract: A portable automated external defibrillator (AED) configured for use with a packaged pair of defibrillator electrodes of the type electrically coupled to one another within the package and having lead wires extending from the package and an electrical connector on the ends of the lead wires. The AED includes a case with an electrode compartment configured to hold the packaged electrodes, and an openable lid for enclosing the compartment. Electrode terminals configured for electrical interconnection to the electrical connector of the electrodes, a speaker and an LED display are positioned within the electrode compartment. An operator-actuated rescue switch and a rescue LED display are positioned on the outside of the case. A high voltage circuit generates defibrillation pulses and applies the pulses to the electrode terminals. The operation of the AED is controlled by a digital control system. Rescue mode operation of the AED is initiated when the lid is opened.
