Abstract: A system for performing necking operations on a can body includes a necker machine and a positioning system. The necker machine includes a frame; a processing arrangement having a plurality of components movable relative to the frame for performing the necking operations on the can body, and a drive motor having a shaft operatively coupled to the processing arrangement for moving the processing arrangement relative to the frame. The positioning system includes: an encoder associated with the drive motor for monitoring a rotational displacement of the shaft and a controller in communication with the encoder and the drive motor. The controller is structured and programmed to: receive an input from a user, the input being indicative of a desired movement of the processing arrangement relative to the frame, and to operate the drive motor using feedback from the encoder such that the desired movement of the processing arrangement is achieved.

Abstract: The physiological or mental functioning of a patient is assessed by subjecting a patient to a protocol expected to activate or suppress the neurhormonal systems that regulate blood flow. A physiological signal indicative of the cardiac cycle, such as the electrocardiograph signal, is then monitored in synchrony with performance of the protocol. The physiological signal is processed to quantify the low frequency oscillation during different conditions during the protocol, and the results are interpreted in terms of cardiovascular changes, such as changes in blood flow to active tissues in the body. The results are then compared to normative data to assess the physiological or mental functioning of the patent.
