摘要： An apparatus coupler, apparatus and method for indicating whether a coupler of a locomotive is in a coupled or uncoupled state is provided. The apparatus comprising: a sensor positioned on a portion of the coupler, wherein the sensor provides a real-time signal indicative of either a coupled or an uncoupled state of a coupler, wherein the signal is transmitted wirelessly by a transmitter in operable communication with the sensor. The method comprising: providing a signal indicative of the presence or proximity of a second coupler to the first coupler, the signal being provided by a sensor configured to provide the signal as the state of the coupler has changed; transmitting the signal wirelessly to a controller; processing the signal with a control algorithm resident upon the controller; and providing visually perceivable indication of the position of the coupler.

摘要： A wireless position sensing device is provided for monitoring railyard equipment status. The device comprises a gravity sensing mechanism for sensing an angular displacement with respect to a substantially vertical line, and for generating a displacement signal upon sensing a change in angular displacement exceeding approximately 40 degrees. A processing mechanism, operatively coupled to the gravity sensing mechanism, receives the displacement signal. A radio frequency transmitter, responsive to the processing mechanism, transmits a data signal indicative of the angular displacement. The processing mechanism is programmed to activate the radio frequency transmitter upon receipt of the displacement signal. The gravity sensing mechanism is affixed, attached, or mechanically coupled to railyard equipment comprising at least one of a manually operated rail switch or a safety indicator.

摘要： A method and apparatus for determining the attenuation of an RF signal caused by a DPF at an unknown or different ambient temperature than the temperature used for DPF sensor calibration is disclosed. The method and apparatus determine the sensor attenuation just prior to determining the DPF attenuation by disconnecting the antennas and determining the attenuation of a loopback path. This sensor attenuation can then be deducted from the attenuation determined for the normal path that includes the attenuation caused by the loopback path, the cables, and the DPF. This method compensates for variation in the attenuation of the sensor caused by changes in ambient temperature of the sensor. Further temperature compensation is be achieved by determining additional factors to account for variations caused by changes in ambient temperature.
