Patent attributes
An apparatus for attaching a device to a circular structure is disclosed. In one embodiment, the apparatus includes a clamp body attached to the outer surface of the circular structure using a strap, which can be attached to the clamp body using a spring that maintains an attachment force to prevent movement of the clamp body over a wide range of temperatures and temperature cycling of the circular structure and the strap. In one embodiment, the device can be installed in the clamp body and coupled to the outer surface of the circular structure using one or more spring washers that maintain an attachment force between the device and the outer surface of the circular structure to prevent detachment of the device from the outer surface of the circular structure over a wide range of temperatures and temperature cycling of the circular structure.
