This application note discusses program flow control that is predicated on a user’s interaction with graphical interfaces, namely, buttons, scroll lists, and dialog boxes.
The key idea is that the calls to the macro functions are configured into a control loop. Also key is that those functions that have UI widgets that await user action, are not followed by any executable statements, they are wholly contained within a function block. In addition, all variables used at decision points should be either global or at script level so that all functions are cognizant of the variables’ existence and value.
The NICO Smart Amplifier is specifically designed to measure thoracic impedance for performing noninvasive cardiac output measurements. The amplifier terminates in two connectors for impedance (Z) and its derivative (dZ), and has a 3 m cable that connects directly to an AMI100D Amplifier Input Module. Use with EL500 series disposable electrodes and LEAD131 for a four-spot […]
NIRS and CNAP—Pairing great tools for great data Cerebral hemoglobin concentration (blood mass in the brain) is frequently measured in the prefrontal cortex, and systemic arterial blood pressure is known to be a variable factor based on the hemoglobin concentration. A leg pressure cuff was used to constrict and release blood flow to create a […]
