Abstract: A dental tool configured for being held by a dental apparatus, the dental tool having at least one material-removing edge in a front portion thereof and a gripping portion in a rear portion thereof, wherein the dental tool comprises a transponder. A system may be provided for receiving data from the transponder and displaying an indication thereof to a user and/or process the data to assist a user in dental activities.

Abstract: A vehicle shock absorber system configured with more than one pressure cylinder that provides advantageous damping characteristics for different loads. There is provided a vehicle shock absorber system having a primary pressure cylinder including upper and lower primary chambers separated by a primary piston head, an auxiliary pressure cylinder including upper and lower auxiliary chambers separated by an auxiliary piston head, a first connection conduit connecting the upper primary chamber and the upper auxiliary chamber, a second connection conduit connecting the lower primary chamber and the lower auxiliary chamber, and a cylinder valve arrangement configured to regulate fluid flow to the auxiliary pressure cylinder.

Abstract: A vehicle differential inversion assembly for splitting the torque of the vehicle power source two ways to opposite sides of the vehicle, to a set of wheels; a left wheel and a right wheel. The wheels are supported by respective independent left and right suspensions allowing vertical travel of each wheel. The assembly features a differential module for splitting the torque two ways. The differential module is disposed between the left wheel and the right wheel and has a left side output and a right side output. The outputs spin at opposed directions. A left output axle couples with the left side output and extends to the left of the differential module. A right output axle couples with the right side output and extends to the right of the differential module. A left wheel axle is cross-coupled with the right output axle by a right inversion joint disposed at a distance to the right of the differential module. The left wheel axle extends toward and turns the left wheel.

The wheels are supported by respective independent left and right suspensions allowing vertical travel of each wheel. The assembly features a differential module for splitting the torque two ways. The differential module is disposed between the left wheel and the right wheel and has a left side output and a right side out-put. The outputs spin at opposed directions. A left output axle couples with the left side output and extends to the left of the differential module. A right output axle couples with the right side output and extends to the right of the differential module. A left wheel axle is cross-coupled with the right output axle by a right inversion joint disposed at a distance to the right of the differential module.
