In one embodiment, a method of deforming a MEMS structure includes providing a base layer, providing a first piezoelectric slab operably connected to a surface of the base layer, determining a desired deformation of the base layer, applying a first potential to a first electrode operably connected to the first piezoelectric slab, applying a second potential to a second electrode operably connected to the first piezoelectric slab, and deforming the base layer with the first piezoelectric slab using the applied first potential and the applied second potential based upon the determined desired deformation.

A system measures an amount of wear in athletic footwear by measuring the amount of shock transmitted to a user. The measured shock is used to indicate an amount of how much cushioning has been lost by the footwear. The amount of wear is proportional to the loss of cushioning and an increase in transmitted shock to the user.

A method and system for onboard zero offset compensation for ATV electric power assist steering (EPAS) torque sensor. An electric assist torque can be applied to an EPAS motor in a clockwise and a counterclockwise direction until a movement is generated in a steering column. A threshold value of torque signal generated by the torque sensor in both directions can be stored when the applied torque exceeds a reaction torque to cause acceleration of a shaft. The reaction torque can be determined under conditions such as, for example, when no one is holding the handle bars and the wheels are free from obstruction. The magnitude of the torque signals are approximately equivalent and an absolute magnitude of the torque signals falls below a general torque limit that can be set under ideal conditions with the ATV. Thereafter, an auto zeroing operation can be performed a number of times throughout the life of the ATV and the error due to offset drift of the sensor can be reduced.

A universal dental implant abutment system is provided which includes an abutment collar and a fixation screw. The abutment collar has a proximal end portion adapted for fixation to a dental prosthesis and a distal end portion adapted for coupling with an implant body. The fixation screw is disposed within a longitudinal bore of the abutment collar and has a threaded distal end for securement to the implant body. The fixation screw has a head portion formed on a proximal end thereof, the head portion having a longitudinally directed bore formed therein. The longitudinal bore of the head of the fixation screw is formed with two longitudinally spaced sections. One section has a non-circular cross-sectional contour adapted for receiving a driving tool therein. The other section has internal threads formed therein adapted for threaded engagement with a retention fastener of a prosthesis.
