A surveillance camera assembly with external adjusting ring has a camera and a cover. Also provided is a celecoxib drug substance wherein the celecoxib is present, in at least a detectable amount, as amorphous celecoxib. The motor energization circuitry is appropriately controlled by a central processor. If the second hold time is twice the first hold time, then the propagation time for signals between the two devices can be determined solely by time measurements made by the local device. When the suture anchor is within cancellous bone tissue, the elastic properties of the insertion tool deploy the suture anchor to an orientation in which the suture anchor cannot fit through the bone hole, thereby firmly anchoring the suture anchor in the human bone. It is thereby possible to reduce, minimize or prevent flickering generated in the entire region of a display screen.
