Abstract: A continuously variable transmission (CVT) system, which turns the rear wheels of a lawn mower or similar vehicle at different speeds in a coordinated method with the front steering wheels in order to achieve the best turning radius (including a tight or zero turn radius, if desired) under most conditions. The system comprises two stages: the first stage comprising a Fixed Center Distance CVT pulley system, and the second stage comprising dual CVTs (e.g., left and right) that input into dual gear reducers (left and right), which are mechanically connected to the rear wheels. The second stage dual CVTs (left and right) are synchronized with the steering wheel, thus achieving different rear wheel speeds and/or directions based on the steering wheel position.

Abstract: An apparatus for removably attaching dealer tags to various vehicles, comprising two or more mounting devices, each comprising a center portion with a mounting hole for mounting the device on the vehicle's tag or license mounting structure using a screw or bolt or similar mounting means. At one end of the device is a mounting post supported by a mounting post support with a ridge, protrusion, or indentation on two opposing sides. The mounting post support is flexibly attached to the center portion, and can be bent around and removably attached to the center portion by means of inserting the ridge or protrusions into corresponding holes or slots in the sides of the center portion. The other end of the device comprises a flexible arm or structure with a hole adapted to fit over the mounting post.

Abstract: An electric cart with one or more lightweight, quick-change batteries or battery packs mounted on the cart frame. The cart body has battery pack access openings to provide easy access to remove and replace battery packs during racing operations. The batteries are easily removed and replaced so that a particular cart can be “refueled” in a matter of seconds. The batteries being removed are placed on a charger, and can be placed back into service relatively quickly. Lithium Ion batteries may be used for the battery packs. The electric cart also may include electrically-adjustable pedals and seats.

Abstract: A system and related methods to automatically equalize acceleration rates and speeds of an electric go-kart based on the weight and other characteristics of the driver. Each kart is equipped with a transponder with a unique frequency that is controlled by a remote control transmitter via radio frequency (RF). The remote control transmitter is capable of changing the speed settings of the electric motor controller on each kart on the track before, after and during a race. Each driver is issued a “Driver's License” in the form of a card with a magnetic stripe that contains, but is not limited to, information on the driver's account balance, driver's race level, and the driver's weight. This information is read from the Driver's License card and used to adjust the speed and acceleration rate of the electric motor of the kart being driven by that participant. The card can be read at the Point-of-Sale (POS) (i.e., cashier, or check-in), or by a card reader on each individual kart.

Abstract: A medicine cap with a timing mechanism that automatically resets upon the removal of the cap from a medicine bottle. A timing device is housed within a medicine camp, with a diaphragm housed below the timing device. The diaphragm has a rod extending upward from a central location, and fastening the cap onto a bottle or container causes the rod to be pushed up into contact with, and activate, the timing device. Upon removal of the cap from the bottle or container, the rod loses contact with the timing device, and the timer is reset. The cap may comprise multiple pieces, so the cap may be used in child-proof mode by the engagement and disengagement of splines on the cap housing and a cap insert. Means are supplied for enabling the constant engaging of the splines.

Abstract: A PTO engagement assembly comprising an electric motor mechanically connected to a lever arm through a set or series of gears. The electric motor turns both forward and backward, causing the lever arm to move forward and backward as well. A cable looped around the end of the lever arm (or otherwise connected or fastened to the lever arm at some point along the lever arm) moves inward or outward as the lever arm moves. The electric motor may controlled by an electric switch. Mounting holes and brackets may be used to fasten the PTO engagement assembly to the mower.

Abstract: An adjustable spindle assembly comprising a spindle housing, a keyed spindle shaft rotatably connected to the spindle housing, a mow ball rotatably connected to one end of the keyed spindle shaft, and a string carrier assembly adjustably connected in between the spindle housing and the mow ball. The string carrier assembly includes a pair of string guides and string holders for securing cutting string to the string carrier assembly without the use of tools. In addition, the string carrier assembly may be moved along the spindle shaft between the spindle housing and the mow ball without the use of tools. A pulley may be connected to a second end of the keyed spindle shaft. The mow ball may have a removable wear point.

Abstract: An electric linear deck lift assembly for raising and lowering in a controlled and accurate manner the cutting deck of a lawnmower to a variety of different heights, including preset heights. An electric motor drives a linear drive rod connected to the cutting deck, thus raising and lowering the cutting deck to particular heights as determined by a positional sensor which monitors the position of the linear drive rod or an encoder which monitors the direction and number of rotations of the electric motor. Also disclosed is a combination of two or more deck lift assemblies for raising and lowering different sides of a cutting deck.
