Abstract
Examples described herein provide an aircraft that includes an auxiliary power unit, a controller, and an identification module. The identification module includes a plurality of digital potentiometers to store information about the auxiliary power unit and readable by the controller.
Claims15
An aircraft comprising:
- an auxiliary power unit;
- a controller;
- and
- an identification module comprising a connector and a plurality of digital potentiometers, the identification module configured to store information about the auxiliary power unit and readable by the controller,
- wherein the connector is configured to electrically connect the identification module to the auxiliary power unit, and to program the plurality of digital potentiometers with a desired resistance value via the controller to store analog coded identification (ID) information of the auxiliary power unit and binary coded information indicative of a serial number of the auxiliary power unit, and
- wherein the analog coded ID information is generated as a resistance-based coded value that is produced in response to programing at least one digital potentiometer among the plurality of digital potentiometers with the desired resistance value.

A system comprising:
- a turbine engine of an aircraft;
- a controller;
- and
- an identification module comprising a plurality of digital potentiometers, the identification module configured to store information about the turbine engine of the aircraft and readable by the controller,
- wherein a connector is configured to electrically connect the identification module to the turbine engine, and to program the plurality of digital potentiometers with a desired resistance value via the controller,
- wherein the connector is configured to electrically connect the identification module to the turbine engine, and to program the plurality of digital potentiometers via the controller to store analog coded identification (ID) information the turbine engine and binary coded information indicative of a serial number of the turbine engine, and
- wherein the analog coded ID information is generated as a resistance-based coded value that is produced in response to programing at least one digital potentiometer among the plurality of digital potentiometers with the desired resistance value.
