  • Patent number: 11951868
    Abstract: The disclosure is directed at an apparatus for an active converter dolly for use in a tractor-trailer configuration. In one aspect, the apparatus includes a system to connect a first trailer towed behind a towing vehicle to a second trailer. The apparatus further includes a kinetic energy recovery device for translating the mechanical motions or actions of the dolly into electricity or electrical energy so that this energy can be used to charge a battery or to power other functionality for either the dolly or the tractor-trailer. The active dolly may also operate to assist in shunting the tractor-trailer. The active dolly is operable in a number of modes to increase vehicle performance and efficiency.

  • Publication number: 20190388635
    Abstract: A bougie having the dimensions of a standard bougie used widely by first responders is further configured to emit tight with an intensity that transilmminates a patient's neck; thus the position of the bougie is visible to the first responder when placed in the patient's airway. The bougie includes a light source, which may be a luminescent chemical combination contained in a chamber of the bougie. The luminescent chemical may have a high intensity and a short duration. The light source may be a light-emitting diode powered by an onboard battery and emitting light into a fiber-optic cable that emits light from the distal end and/or from interruptions in a reflecting coating that allows transverse exit of some of the light. The light source may be a chemilmninescent material or compound. All components of the bougie are sized to pass through an endotracheal tube without removing any of the components.

  • Publication number: 20070088421
    Abstract: Device useful for implanting an implantable device within the vasculature of a patient. The device includes a deployment line, a control component for actuating the deployment line, and an actuation mechanism for translating constant-rate actuation of the control component into variable rate retraction of the deployment line from a remotely deployable implantable device. Suitable implantable devices include, for example, stents and stent grafts.

  • Patent number: 7184072
    Abstract: A system and apparatus for acquiring images of electric transmission line tower structures, equipment attached to said tower structures, and transmission lines suspended from said towers. The system uses a fixed wing aircraft and an arrangement of at least one still camera, means for detecting a tower structure, a data storage unit, and a central processing unit containing operational software. The central processing unit is connected to the camera, the means for detecting a tower structure, and the storage unit. The detection means is a laser altimeter or a combination of preset longitude/latitude coordinates for tower locations and a GPS unit which supplies continuous longitude/latitude coordinates for the aircraft location for comparison to those preset coordinates. The aircraft is flown along the transmission line at a predetermined altitude above the tops of said towers (60–100 feet).
