  • AUTOMATED TEST MANAGEMENT SYSTEM FOR ELECTRONIC CONTROL MODULE
    Publication number: 20140354321
    Abstract: An automatable management system for testing one or more electronic control modules (ECMs), in one or more machines, is disclosed. The one or more ECMs are switchably connected to a testing unit (TU). The system includes at least one ECM connector, connectable to the one or more ECMs. The at least one ECM connector is one of a male connector or a female connector. Similarly, the system includes at least one TU connector connectable with the TU. Further, at least one actuator is operably connectable to at least one of the at least one ECM connector and the at least one TU connector. The actuator is configured to facilitate an electrical connection between the ECM and the testing unit in response to a relay signal generated by the testing unit.

  • Controlled motion in a hydraulically actuated system
    Patent number: 8037807
    Abstract: A machine configured to prevent unintentional motion in a linkage pivotally connected to a frame may include a first hydraulic actuator connected to the linkage and a second hydraulic actuator connected to the linkage. The machine may include a sensor and an electronic control module in communication with the sensor. The electronic control module may be configured to close a valve of the first hydraulic cylinder and/or cancel an actuation command to one of the first hydraulic actuator and the second hydraulic actuator in response to the electronic control module determining unintentional motion of the linkage has occurred based on the sensor.
