ADJUSTABLE HALL EFFECT SENSOR SYSTEM

Publication number: 8,970,205

Application number: 13/420,567

A adjustable Hall effect sensor system having a sensor positioning component is described. In one embodiment, the Hall effect sensor system is an independently adjustable sensor system, having a plurality of Hall effect sensor, wherein one Hall effect sensor may be displaced and adjusted without effecting the location of another Hall effect sensor. A sensor positioning component comprising a paddle coupled to a main body portion by a more narrow neck is described. A cam may be configured on a paddle and provide for fine tuning the position of a Hall effect sensor. In one embodiment the main body and extensions are comprised essentially of a circuit board.

Transverse and/or commutated flux systems having laminated and powdered metal portions

Publication number: 8,952,590

Application number: 13/291,392

Electrical machines, for example transverse flux machines and/or commutated flux machines, may be configured to achieve increased efficiency, increased output torque, and/or reduced operating losses via use of laminated materials in connection with powdered metal materials. For example, stacks of laminated materials may be coupled to powdered metal teeth to form portions of a stator in an electrical machine.

TOOTHBRUSH WITH FORMABLE HANDLE

Publication number: 8,931,855

Application number: 14/089,735

A formable handle toothbrush has a handle portion that allows a user to heat and form the handle to the shape of their hand to provide for more secure grip of the toothbrush. In one embodiment, a hand formable toothbrush has a toothbrush head attached to a shank that can be inserted into a socket within the toothbrush handle. This configuration allows for the use of replacement toothbrush heads. This makes manufacturing of higher cost handles more economical, as the formable handle portions would not be thrown out when the toothbrush head needs replacement. To customize the formable handle portion, a user may simply place the toothbrush, or handle portion of the toothbrush, in boiling water for a period of time and then remove the toothbrush handle, allow it to cool to a safe temperature and then grasp the handle to form it into the shape of their hand.
