Abstract

A system includes a sensor, a second connector, a local processor, a first telemetry module, a second telemetry module, and a remote processor. The sensor is coupled to a cord and the cord has a first connector. The second connector is coupled to a housing. The second connector is configured to mate with the first connector. The local processor is coupled to the second connector and disposed in the housing. The local processor is configured to execute instructions stored in a local memory. The local memory is disposed in the housing. The local processor is configured to generate calculated data based on a signal received at the second connector. The signal corresponds to a parameter measured by the sensor. The first telemetry module is coupled to the local processor and is configured to wirelessly communicate the calculated data. The second telemetry module is configured to communicate with the first telemetry module. The remote processor is coupled to the second telemetry module. The remote processor is configured to generate output data based on the calculated data.
