Abstract: Controlling internal humidity for a device by receiving an environmental parameter relating to a humidity control in the device, analyzing the environmental parameter to determine a humidity condition of the device, and sending a signal to activate a heater based on the humidity condition. A device including humidity control includes a humidity measuring arrangement, a temperature measuring arrangement, a processor receiving a humidity input from the humidity measuring arrangement and a temperature input from the temperature measuring arrangement, the processor comparing the humidity input and temperature input to stored data to determine a humidity condition of the device and a heater which is activated upon the determination of a predetermined humidity condition.

Abstract: An on-board hot bearing detector system includes a microprocessor and heat sensors mounted on the train cars for sensing the bearing temperatures. Diagnostic circuitry is also provided to monitor the sensors and detect if a sensor is open or short. Additionally, the train line is controlled by the microprocessor and is provided with a current limiting device for protection against large currents in case of a short.

Abstract: A train analysis system for analyzing a wheel condition such as wheel bearing temperature includes circuitry for identifying the wheels of a railroad car, circuitry for averaging the condition of each wheel of a car, and circuitry for establishing a threshold level for said condition, dependent on said averaging. When a wheel cannot be identified, a threshold level is set which is below the maximum level for identified wheels.

Abstract: This invention relates to a device for monitoring the temperature of the wheels of passing railroad cars. More particularly, this device includes a self-calibration function wherein a predetermined heat source is attached to the device, a fixed amplifier amplifies the resulting electric signal so as to generate a signal comparable in magnitude to that generated by a passing train, a variable gain amplifier further amplifies the signal, and the resulting signal is converted to a digital signal. The digital signal is used as a signal to the feedback input of a variable gain amplifier. In response to the digital signal, the variable gain amplifier adjusts its gain until the feedback signal reaches a predetermined value.
