An air quality system includes an air precleaner, a filter identification component, and a control module. The air precleaner has a precleaner housing and a filter disposed inside the precleaner housing. The filter identification component is positioned within the precleaner housing at a first position and is mounted on the filter. The control module is positioned within the precleaner housing at a second position and is configured to emit an electrical field and communicate with the filter identification component via the emitted electrical field.

Systems and methods are disclosed for providing a deployable fairing system to a tractor trailer. The deployable fairing system includes an actuator used to extend the deployable fairing from an unextended configuration to an extended configuration to occupy a portion of a gap area that exists between a tractor and an attached trailer. The deployable fairing includes deployable upper and/or lower horizontal assemblies that are pivotally coupled to a frame attached to the tractor/cab, and two side panels that are pivotally coupled to one or both of the upper and lower horizontal assemblies. The deployable upper and lower horizontal assemblies and the two side panels fold in on one another along multiple hinged axes in the unextended configuration, and extend rearward from the top and sides of the tractor in the extended configuration to cover a portion of the gap. The fairing may advantageously flair from front to the rear.

Systems and methods are provided for a dual-access refrigeration space with conveyance system. The dual-access refrigeration space being accessible from both inside and outside the passenger cabin of a vehicle, and the conveyance system capable of conveying objects within the dual-access refrigeration space. The conveyance of such objects enabling passengers of the vehicle to access refrigerated objects that may have been loaded from an area external to the passenger cab without the passengers needing to exit the vehicle. In some examples, such convention may be reversed such that the refrigeration space within a passenger cabin may be utilized by a user outside the passenger cabin.

Systems, methods, and devices for a vehicle door or window are disclosed herein. A vehicle includes a vehicle body and a cabin located within the body of the vehicle, wherein the cabin includes an interior that is configured to accommodate at least one person. The vehicle includes at least one seat located in the interior of the cabin that is configured for seating a user. The vehicle includes at least one door that provides ingress and egress to the interior of the cabin of the vehicle, and the at least one door is located with respect to the body such that the door opens to provide ingress and egress into the cabin from a backside of the seat.

The present invention describes a tractor trailer shower unit which provides a shower enclosure having shower head and floor drain features. The shower unit also provides water heating and pumping equipment as well as a waste water collection tank, making it particularly suited for use within a tractor trailer rig. The shower unit is powered by the electrical system of the tractor trailer rig.

A selective filtration system for an operator cab attached to an agricultural vehicle. A HVAC unit supplies conditioned air to an operator space selectively from a CAT 4 filter and a CAT 2 filter. A pressurization blower and two way valve controls flow from the CAT 4 filter to the HVAC unit. Control of flow or isolation of the CAT 2 filter is provided by pressure variations within the system. The CAT 4 filter and CAT 2 filter are isolated from the ambient when they are not in use.

A method for manufacturing a bunk assembly for a transit vehicle is provided. The method includes forming an upper shell and forming a lower shell. The method further includes installing a frame between the upper shell and the lower shell and joining the upper shell and the lower shell together to form a support panel. The method further includes drilling a fill hole and a vent hole in the lower shell, the vent hole having a first diameter, and filling the support panel with foam via the fill hole and such that air contained within the support assembly is vented through the vent hole. The method further includes redrilling the vent hole to a second diameter to form a mount hole, the second diameter being greater than the first diameter, and mounting hardware to the support panel at the mounting hole.

A vehicle includes an operator cab having a frame defining an opening and a permeable material sheet mounted adjacent the frame to at least partially cover the opening. The permeable material sheet has a plurality of apertures. The operator cab further includes an air nozzle positioned proximal to the opening and positioned so that the air nozzle directs an airflow to contact at least a portion of the permeable material sheet to form a swirling air current proximal to at least one of the plurality of apertures.
