Abstract: Safety systems and material testing systems including safety systems are disclosed. An example material testing system includes: at least one actuator configured to control one or more operator-accessible components of the material testing system; an actuator disabling circuit configured to disable the at least one actuator; and one or more processors configured to: control the at least one actuator based on a material testing process; monitor a plurality of inputs associated with operation of the material testing system; determine, based on the plurality of inputs and the material testing process, a state of the material testing system from a plurality of predetermined states, the predetermined states comprising one or more unrestricted states and one or more restricted states; and control the actuator disabling circuit based on the determined state.

Abstract: A system and method for automatically analyzing impedance and pH data from an esophageal probe includes a data collection system that collects and stores the output from the sensors for a certain period of time to locate reflux episodes in the waveforms. The data analysis system uses wavelet analysis to assist in locating bolus entry and exit points in the waveforms and to smooth waveforms for additional analysis.

Abstract: A system and method for displaying an esophageal operation includes a display device, an interface capable of receiving esophageal impedance and pressure measurements, and a processing system in communication with the display device, the interface, and an esophageal operation model. The processing system is configured to receive a plurality of impedance values from a first plurality of spaced-apart esophageal locations, receive a plurality of pressure values from a second plurality of spaced-apart esophageal locations, process the plurality of impedance values and the plurality of pressure values with the esophageal operation model, display the plurality of impedance values on the display device as a bolus transit, and display the plurality of pressure values on the display device as operational esophagus movement.
