A piezoelectric energy harvesting system for converting mechanical energy of a tire of a vehicle to electrical energy includes sets of piezoelectric beam assemblies, a tire electrical jack, a conductive bearing, and an electrical storage unit. The sets of piezoelectric beam assemblies are embedded in multiple layers of the tire of the vehicle and electrically connected in a parallel configuration. Each of the sets of the piezoelectric beam assemblies are electrically connected in a series configuration for converting mechanical strains into electrical energy. The tire electrical jack is mounted on a rim of the tire and receives the electrical energy generated by the sets of piezoelectric beam assemblies via output terminals. The conductive bearing transmits the electrical energy received by the tire electrical jack to the electrical storage unit, which filters, rectifies, adapts and stores the transmitted electrical energy for powering components of the vehicle.

A materials handling equipment has blades of a lifting fork wherein each of the blades engages a blade wheel that moves between a retracted position when the blade is lowered and an extended position when the blade is raised to lift and support a load. The blade wheels have a plurality of tires linearly aligned on a common axis, the tires each having a circular circumference and a sinusoidally varying peripheral surface. The sinusoidally varying peripheral surfaces have relative peaks and valleys uniformly spaced around the circular circumference wherein the peaks and valleys are mutually nested.

A combination seat belt restraint system cutter and glass break tool mounted onto and around the seat belt of an automotive vehicle at a predetermined position for use in cutting the web of the seat belt in the event of a seat belt release latch jam or inoperability resulting in the severing of the seat belt at said position resulting in the tool being freed for use in breaking the glass of a window of the vehicle. The combination tool also being maintained in a fixed position adjacent the safety belt extension/retraction aperture by a strap.

Disclosed is a wheel front burr removing device, comprising an upper servo motor, a right support plate, a right slide plate, right guide rails, a right cylinder I, a right cylinder II, a right driven conical friction wheel, a rim burr cutter, a right workbench, a right shaft, a mandrel and the like. Rim burrs are removed on the right station while cap section burrs are removed on the left station, double stations are adopted for machining, so the efficiency is very high.

A gear driven by wobble movement contains an ergonomic pendulum (D), a centric disk (C) and a flywheel (A) having a common axis (S) of rotation. In the axis (S) of rotation a shaft (H) is placed which is joined to the pendulum (D). The mutual concentric position of the centric disk (C) and the flywheel (A) is delimitated by planet disk (B) which contacts the periphery of the centric disk (C) and the internal periphery of the flywheel (A) and is joined rotatably to the supporting structure (T). The supporting structure (T) is fixed to the linked structure which fixes the supporting structure (T), together with the planet disk (B), against rotation with respect to the axis (S) of rotation. A first freewheel (V1) is situated between the shaft (H) and flywheel (A) and a second freewheel (V2) is situated between the shaft (H) and centric disc (C).
