An orthopedic knee prosthesis includes a femoral component, a tibial bearing, a tibial component, a first magnetic portion associated with the femoral component and including a first pole having a first pole polarity the first magnetic portion not physically interrupting any articulating portion of the curved medial condyle surface or curved lateral condyle surface, and a second magnetic portion associated with one or both of the tibial bearing and/or the tibial component and including a second pole having a second pole polarity, the second pole polarity the same as the first pole polarity, the second magnetic portion not physically interrupting any articulating portion of the concave medial bearing surface or concave lateral bearing surface, wherein the first pole and the second pole are in sufficient proximity to each other such that a magnetic repulsive force is present therebetween.

Systems and methods for magnetic joints

A lighted level including a frame having parallel working surfaces and an inner connecting web having an aperture with a pair of notches for supporting a liquid-containing vial. The level includes a light emitting diode for illuminating the vial. The level is constructed for automatic drop-in assembly of each of the component parts, including a printed circuit board containing the lighting circuitry, without requiring wires, screws, pins, pegs or bolts.

Level

A vehicle overload detector characterized as mechanism which, after installation, is calibrated to a preselected initial setting, where upon loading a vehicle, the resulting metered deflection visibly advises the operator of any possible overload condition. Restated otherwise, the mechanism measures vehicle frame deflection, employing two cables, oppositely wound around a control pulley, for establishing the aforesaid initial setting and the deflected setting, respectively.

Vehicle overload detector

A device for estimating postage requirements for envelopes and the like, and comprising a holder for supporting the envelope during the estimating process, a balancing lever pivotally secured to the holder and having a fulcrum about which the device may rock, and a recess provided at the outer end of the lever for receiving weighted elements therein which are calculated to generally counter balance the envelope in a manner for providing an estimate of the postage requirements for mailing of the letter in the postal system.
