Abstract: A vaporizer device includes various modular components. The vaporizer device includes a first subassembly. The first subassembly includes a cartridge connector that secures a vaporizer cartridge to the vaporizer device and includes at least two receptacle contacts that electrically communicate with the vaporizer cartridge. The vaporizer device includes a second subassembly. The second subassembly includes a skeleton defining a rigid tray that retains at least a power source. The vaporizer device also includes a third subassembly. The third subassembly includes a plurality of charging contacts that supply power to the power source, and an end cap that encloses an end of the vaporizer device.

Abstract: A vehicle combining the attributes of a tractor and a utility vehicle includes a three point linkage and other locations to which a plurality of attachments for performing grooming or working operations on a ground or turf surface may be couple. The vehicle includes a front mounted engine, a mid-mounted operator compartment and a rear mounted bed or box. A PTO shaft and/or a hydraulic power system of the vehicle power attachments that require power. A control system and a visual display and data entry device linked thereto are provided for allowing an authorized person to setup, store and thereafter use an operational profile for each attachment that is to be coupled to the vehicle. In a rate dependent attachment, the control system maintains the ground speed and the attachment implement in a fixed ratio. A down/up control is used to signal the start and end of an operational sequence to the control system.

Abstract: This invention relates to a mower and a tracked implement that convert from one to the other by coupling a mower unit or a tracked unit to a common drive unit. The drive unit is thus used in both products to provide cost savings in the purchase of the equipment. In the tracked unit, a cab for enclosing the operator's station is part of the tracked unit and gets mounted to the drive unit when the tracked unit is coupled to the drive unit. A pair of idlers rotate on pivot axes that are fixed relative to a pivotal idler support that carries the idlers. The pivot point for the idler support is chosen to prevent track elongation when the tracked unit climbs obstructions such as a curb. In the mower unit, a relatively heavy cutting deck is used and spring biased weight transfer arms transfer some of the deck weight to the mower frame.

Abstract: A system for supplying hydrogen gas to a lighter-than-air (LTA) vehicle includes a manifold having multiple vessels. Each vessel has a first chamber that is separated from a second chamber by a barrier. A trigger assembly integrated with the barrier allows a liquid to be combined with a reactant and a catalyst in the second chamber to form a chemical reaction to generate hydrogen gas. A pressure relief valve located on each vessel opens to allow the hydrogen gas to exit when a predetermined pressure is reached, and the hydrogen gas is supplied to the LTA vehicle connected to the manifold.
