  • Patent number: 8439595
    Abstract: A vehicle restraining system using an electrical impulse to disable the control system of a targeted vehicle including a roadway module placed at a location to engage the targeted vehicle for delivering the electrical impulse to the vehicle; a roadside module for generating the energy required for the electrical impulse and delivering the energy to the roadway module; and an operator interface module for operating the restraining system. In addition, a method of disabling the control system of a vehicle by delivering an electrical impulse to the vehicle includes the steps of charging a vehicle restraining system; setting the charged vehicle restraining system to disable the next encountered vehicle; detecting the next encountered vehicle, and delivering the electrical impulse to the targeted vehicle.

  • Patent number: 6626870
    Abstract: A syringe assembly is provided which includes a hollow barrel that has an interior wall. The interior wall defines a chamber that retains medication. The hollow barrel also includes a distal end and a proximal end. The distal end of the hollow barrel has a passageway that is in contact with the chamber. The proximal end of the hollow barrel has an aperture. The syringe assembly also includes a primary plunger tip that is slidably positioned, in fluid tight engagement, with the interior wall. The primary plunger tip has a receptor to engage an engager of an elongated tip plunger rod. The syringe assembly also includes a secondary plunger tip that is slidably positioned, in fluid tight engagement, with the interior wall. The secondary plunger tip also has a receptor to engage an engager of a tip plunger rod. The secondary plunger tip is disposed between the primary plunger tip and the proximal end of the hollow barrel.

  • Patent number: H1238
    Abstract: Vehicles that are frequently operated in "off road" conditions are normally equipped with a means by which some form of oscillation is provided to accommodate the uneven terrain over which it traverses. In some instances, the stability of the vehicle is inadequate while in other instances the stability is acceptable; however, the service life of the particular design is in question. The axle suspension 10 of the present invention is mounted to the vehicle frame 12 in a manner whereby the various types of forces encountered during the operation of the vehicle are directed to specific areas of the mounting. Being so directed, the mounting members 38 and 52, utilized in these specific areas of mounting, may be selected to best accommodate the type of loading that will be applied in that area.
