Abstract: A hair drying apparatus includes a body defining an air inlet, an air outlet and an air flow path therethrough. An impeller generates a flow of air from the air inlet, through the air flow path and to the air outlet. A motor drives the impeller and a heating element heats air flowing through the air flow path. The heating element, motor and impeller are supported within the body. A handle is mounted to the body and a housing is at least partially surrounded by the body and at least partially surrounds the air flow path. The motor is supported within the housing. At least one vibration isolation member is located between an inner surface of the body and an outer surface of the housing.

Abstract: An apparatus and method for determining forces on a downhole drilling tool is provided. The downhole tool is provided with a drill collar operatively connectable to the drilling tool, and a sensor mounted about the drill collar. The sensor is adapted to measure deformation of the drill collar whereby forces on the drilling tool are determined. The sensor may be part of a force measurement system, a strain gauge system or a drilling jar system. The drill collar is adapted to magnify and/or isolate the deformation applied to the drill string.
