Abstract: A surgical device includes a handle assembly having a power source; a motor coupled to the power source; and a controller configured to control the motor. The surgical device also includes an adapter assembly configured to selectively couple to the handle assembly; a reload configured to selectively couple to a distal portion of the adapter assembly, the reload including a plurality of fasteners; and an anvil assembly selectively couplable to the distal portion of the adapter assembly, the anvil assembly being movable relative to the reload. The controller is further configured to control the motor to move the anvil assembly from a starting position to a compressed position thereby compressing tissue at a target clamping force between the anvil assembly and the reload.

Abstract: A portable detection system, including a receiver tuned to the frequency of signals transmitted by an aircraft transponder, will detect the presence of an aircraft in proximity to the system. The system has signal processing circuitry to transform the received signals to indicate the altitude of the detected aircraft. A display or alarm may alert the user to the presence of an aircraft. The system is useful to determine whether an aircraft may be engaged in a speed detection and ticketing operation or the closeness of other aircraft. The aircraft detection system may be used in conjunction with a radar detection system to provide a means by which various methods of traffic control can be detected.
