Abstract: A control assembly, a tool and a method. The assembly may include a handle assembly including a first handle portion and a second handle portion, the handle assembly being removably connectable to a tool housing; and pump controls operable to control a pump to drive a tool drive mechanism and thereby an output member. Operation of the pump may require an operator's first hand on a first handle portion and the operator's second hand on a second handle portion. The pump may be operable under the control of the pump controls to drive the drive mechanism when the handle assembly is connected to the housing and when the handle assembly is disconnected from the housing.

Abstract: A fluid-operated, reciprocating piston-style torque wrench and a method of operating the same. The wrench may have pump controls coupled to the torque wrench. The pump controls may be connected to a handle assembly that is coupled to the torque wrench. The handle assembly may include sensors to require two hand operation of the pump controls.

Abstract: An ultrasonic measurement system comprises a processor configured for enhancing a received ultrasonic signal, where the received ultrasonic signal is a frequency domain signal. The enhancing involves deconvolving the received ultrasonic signal to yield a filtered signal, determining autoregressive extrapolation parameters based on frequency amplitude fluctuations of the filtered signal within a frequency range over which a corresponding reference signal has a high signal-to-noise ratio, and carrying out an autoregressive spectral extrapolation of the filtered signal using the autoregressive extrapolation parameters to yield an enhanced ultrasonic signal.
