Publication number: 20240057927Abstract: A system for evaluating neurologic dysfunction of a subject includes an odorant generator configured to deliver an odorant stimulation to the subject, an auditory generator configured to deliver an audible stimulation to the subject, a vibrotactile stimulator configured to generate a somatosensory stimulation to the subject, a plurality of electrodes configured to be attached to the subject at respective different locations, and at least one processor. The plurality of electrodes are configured to collect neural signals from the subject as a result of the odorant stimulation, the audible stimulation, and the somatosensory stimulation. The at least one processor is configured to process the neural signals from the plurality of electrodes and generate an assessment of neurologic dysfunction of the subject.Type: ApplicationFiled: September 19, 2023Publication date: February 22, 2024Inventors: David William SMITH, Richard MICHELLI, William David WOOLF

Publication number: 20230339271Abstract: A hitch system for connecting a towed vehicle to a towing vehicle includes a hitch apparatus attached to the towing vehicle and a control system operably associated with the hitch apparatus. The hitch apparatus includes a frame movably secured to the towing vehicle, and a hitch member secured to the frame that is configured to receive a coupling apparatus of the towed vehicle. The frame is movable relative to the towing vehicle such that the hitch member can be positioned rearward of the towing vehicle at any location within a defined three-dimensional space. The frame is configured to maintain the hitch member in a substantially level orientation at all locations within the three-dimensional space. The control system is configured to move the hitch member to a desired location within the three-dimensional space.Type: ApplicationFiled: April 25, 2023Publication date: October 26, 2023Inventors: Carl Michael Anderson, Corey Drew Rasmussen, Mark Wesley Bevington, William David Woolf, Ryan Matthew DelGizzi, Cody Paul Charland

Patent number: 9415647Abstract: An adjustable height hitch apparatus for a trailer includes a base having opposite first and second end portions. An elongated shaft extends outwardly from the base first end portion, and an elongated height adjustment member is attached to the base second end portion. A coupling apparatus, such as a lunette ring, is supportable by the height adjustment member via one or more fasteners at any of a plurality of elevations. The height adjustment member is configured to provide height adjustment for the coupling apparatus of at least about eight inches.Type: GrantFiled: November 25, 2014Date of Patent: August 16, 2016Assignee: TeleSwivel, LLCInventor: William David Woolf

Patent number: 9283821Abstract: A hitch coupler receiving apparatus includes a base having opposite first and second surfaces, and a pair of spaced-apart first and second openings extending through the base from the first surface to the second surface. A pair of opposing, elongated first and second walls extend outwardly from the base first surface in adjacent, spaced-apart relationship. Each wall includes a plurality of spaced apertures formed therethrough. A hitch coupler is secured to the apparatus via a fastener that engages aligned apertures in the respective first and second walls. Each wall overlies a respective one of the first and second openings and includes an access opening. Each access opening is substantially larger than a respective opening in the base and facilitates insertion of a fastener into a respective opening in the base and rotation of the fastener via a tool.Type: GrantFiled: June 27, 2014Date of Patent: March 15, 2016Assignee: TeleSwivel, LLCInventor: William David Woolf

Publication number: 20150137482Abstract: A hitch apparatus for a vehicle includes a microcontroller unit, a drawbar, and a coupling apparatus secured within the drawbar via a pin. The pin and/or the drawbar includes one or more force sensors, each configured to measure a force vector on the pin and/or drawbar during towing of a trailer or other vehicle attached to the coupling apparatus. Each force sensor is electrically connected to the microcontroller unit, and the microcontroller unit is configured to receive force measurement data from each force sensor and process the data for transfer to a vehicle control system via a controller area network bus associated with the vehicle. The microcontroller unit may determine if one or more threshold forces have been exceeded and trigger one or more corrective actions by the vehicle control system in response to determining that a threshold force has been exceeded.Type: ApplicationFiled: November 14, 2014Publication date: May 21, 2015Inventors: William David Woolf, Carl Michael Anderson

Publication number: 20140309840Abstract: Systems and methods for aligning a towing vehicle trailer hitch with the tongue of a trailer/towed vehicle are provided that enable a driver to know when the towing vehicle trailer hitch is close enough to the trailer tongue such that the two can be coupled. A trailer hitch includes a tow bar having a free end configured to be coupled to a trailer tongue. An alignment system includes at least one energy emitter secured to the vehicle that emits energy in the direction of the trailer tongue, and at least two sensors secured to the vehicle in spaced-apart relationship. The energy emitter(s) and sensors may be secured to the trailer or trailer hitch.Type: ApplicationFiled: June 25, 2014Publication date: October 16, 2014Inventors: William David Woolf, Gregory S.
