Abstract: A connector device for connecting a first vehicle to a second vehicle, the connector device comprising an upper frame and a lower frame, where the rear side of the upper frame is configured to pivotally connect to the front upper side of the second vehicle, about a first rotation axis, and the rear side of the lower frame is configured to pivotally connect to the front lower side of the second vehicle, about a second rotation axis that is angular in respect to the first rotation axis. The non-zero angle formed between the rotation axes restricts the rotation movements at least about one of these axes. The connector device can be used for forming a removable chain of main and towed vehicle(s) in a manner that enables folding of a towed vehicle over the first vehicle and removably connecting as many vehicles to be towed as required.

Abstract: A dynamic joint structure (DJS) for movably connecting a wheel set to a chassis of a vehicle, and a vehicle including a front such DJS and a rear such DJS. The DJS includes an upper suspension plate having at least one upper recess with an upper opening; a middle suspension plate having at least one middle recess with a middle opening; and at least one connector assembly including: (i) an elongated bolt defining an insert axis “Zi” along its longer side; and (ii) a restriction unit configured to restrict the movement of the bolt over an XiYi plane that is perpendicular to Zi, for enhancing translation of tilting movements of the chassis of the vehicle into steering movements of the vehicle's wheels set to which the DJS connects.

Abstract: The present provides a method for condition monitoring a vehicle and for alerting of irregularities/defects.

Abstract: The present invention provides a vehicle wheel configured to assemble a motor having an uneven weight distribution. The vehicle wheel comprising a rim having an asymmetric structure. The rim comprising a drop center (202) for mounting a tire, side sections (204A-D) extending axially outward from both sides of the drop center (202), bead bases (208A-D) extending axially outwards from said side sections (204A-D), and flanges (210A-D) disposed axially outward of said bead bases. The bead bases having non symmetrical lengths to compensate the uneven weight distribution of said motor on the rim. The drop center having a drop diameter that is compatible with the diameter of the motor for inserting and encapsulating said motor therein, and the asymmetric structure of the rim compensates the uneven weight distribution of said motor on the rim, thus, maintains said wheel balanced with a minimal overall offset from the center line of the rim.

Abstract: A vehicle comprising: •a front wheel set and a rear wheel set, each set comprising two wheels and an axle attached to the said wheels; •a base structure or chassis; •a front elastic pivot structure, connecting the front wheel set to the chassis, wherein said front elastic pivot structure comprises a front set of at least one elastic joint, enabling the chassis to tilt along a front roll axis in respect to the said front wheel set; •a front shock absorber, associated with the front wheel set; •a rear elastic pivot structure, associated with the rear wheel set, wherein said rear elastic pivot structure comprises a rear set of at least one elastic joint, enabling the chassis to tilt along a rear roll axis in respect to the said rear wheel set; and •a rear shock absorber, associated with the rear wheel set.

Abstract: Some embodiments are directed to an adjustment assembly for changing width of a vehicle including at least one pair of wheels, where the adjustment assembly is embedded in the vehicle and is connectable to a pair of front, middle or rear wheels thereof. The adjustment assembly includes, inter alia: a foldable unit connectable to the pair of wheels of the vehicle, configured for changing its overall length over a predefined axis “Y” connecting the centers of the pair of wheels, for adjusting a distance between the pair of wheels it connects to; and a tilting unit operatively associated with the pair of wheels of the vehicle to which the foldable unit connects. The tilting unit is configured for changing angular positioning of the pair of wheels in respect to the “Y” axis, during driving of the vehicle when folded or unfolded.

Abstract: This invention is a new disinfecting and immunizing system for fertilized and unfertilized avian eggs that, by manipulating the ambient air pressure, creates an environment that causes the pores of the eggshells to open, allowing disinfectants and inoculants to be delivered to the eggs in such a manner that the liquid material penetrates through the pores into the shell to a specified depth but does not go beyond the shell to the embryo. The system is designed such that it performs similar but separate processes for disinfection and immunization; each process includes changing the air pressure, spraying appropriate product, and returning the air pressure to initial condition.
