Abstract: Thread repair tools having (i) a disc-shaped member with an axis of rotation extending through and dissecting first and second major surfaces of the disc-shaped member, (ii) a shaft fixedly connected to or fixedly connectable to the disc-shaped member, with the shaft extending from the second major surface of the disc-shaped member along the axis of rotation; and (iii) an abrasive surface along an outer periphery of the disc-shaped member are disclosed. Methods of making the thread repair tools, and methods of using the thread repair tools are also disclosed. Methods of using the thread repair tools include a method of: (i) connecting the thread repair tool to a hand-held powered device capable of rotating the thread repair tool along the axis of rotation of the thread repair tool, and (ii) abrading an object with the disc-shaped member of the thread repair tool as the thread repair tool is rotated along the axis of rotation by the hand-held powered device.

Abstract: One or more simulations are generated for in-home monitoring. The simulations model sensory detection of a user's physical activities using a different number and/or a different combination of sensors. Each different simulation may thus be associated with an accuracy and a cost, depending on the number and/or combination of sensors. The simulations thus present a range of sensory configurations that balance accuracy and affordability, from which an optimum sensory solution may be determined for the in-home monitoring.
