Methods, devices and systems for evaluating olfactory function are configured to: electronically estimate a user-specific odorant detection threshold sensitivity threshold using at least one target stimulus odorant delivered to a nose of a user; flowably deliver a plurality of different target stimulus odorants to the nose of the user with defined concentrations of the different target stimulus odorants based, at least in part, on the estimated user-specific odorant detection sensitivity threshold; and evaluate olfactory function of the user based on the user's response to the delivered different target stimulus odorants.

Olfactory test systems and methods

An apparatus, module, methods and systems for automated, standardized assessment and analysis of a human olfactory system's odor detection ability as an indicator or predictor of cognitive impairment or change in cognitive health, and other health conditions such as diabetes. Notably, the present invention is operable for use across all age groups of humans and provides quantitative detection and analysis of a human olfactory system's detection ability compared to a relevant demographic population.

Apparatus, method, and system for testing human olfactory systems

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.

Adjustable height hitch apparatus

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.

Hitch coupler receiving apparatus

A hitch apparatus includes a frame configured to be secured to a vehicle and that is pivotable about a first axis, a guide that is movably secured to the frame and pivotable about a second axis substantially transverse to the first axis, and a tow bar movably secured to the guide and movable relative to the guide between retracted and extended positions. The hitch apparatus includes a user controlled positioning system with a user input device that is configured to allow a user to extend and retract the tow bar and to articulate the tow bar up-down and left-right so as to position the tow bar distal end at a desired position within a three-dimensional coordinate system.

Articulating hitch apparatus for vehicles

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.
