Abstract: An autonomous tensioner system that is coupled to a conveyor belt scraper includes a motor that generates a first drive torque and a gearing assembly coupled to the motor such that the gearing assembly is actuated in response to the motor generating the first drive torque. The gearing assembly generates a second drive torque in response to receiving the initial drive torque generated by the motor and the second drive torque is greater than the first drive torque. The autonomous tensioner system includes an output member coupled to the gearing assembly and the conveyor belt scraper. The output member receives the second drive torque from the gearing assembly and rotates in response, thereby generating a rotational torque. The conveyor belt scraper receives the rotational torque from the output member and simultaneously moves at a torque greater than the first drive torque generated by the motor.

Abstract: The present invention provides a peripheral device with limited relative angular movement. The peripheral device is configured for detachable operative interconnection with a computing device and comprises a first portion, a second portion, and an operatively connected peripheral device component. The first portion includes a first hinge portion, which defines an axis of rotation, and comprises a first protrusion and a second protrusion. The first protrusion is disposed axially separated at a predetermined distance from the second protrusion. The second portion includes a second hinge portion, which is operatively interconnected with the first hinge portion to allow the first portion and the second portion to rotate relative to one another about the axis of rotation between a first angle and a second angle. The peripheral device component provides one or more peripheral device functions. The first angle and the second angle at least in part are defined by the first protrusion and the second protrusion.
