Abstract: A control apparatus includes a power supply for providing appropriate current and voltage to modules of the control apparatus. A user interface microprocessor module provides the necessary architecture to handle user inputs as well as programmable control logic. Furthermore, there is a communications microprocessor module initiating data traffic signals among all control apparatus modules through a wireless transceiver module. Finally, a remote control node module through a transceiver interprets and acts upon wireless traffic signals to control an operation. A method of operating a control apparatus where the user operates the apparatus by energizing a power supply for providing appropriate current and voltage to modules of the control apparatus. The user interacts with a user interface microprocessor module that provides the necessary architecture to handle user inputs as well as programmable control logic.

Abstract: The invention concerns a system for sensing train wheels which employs a slotted detector bar. Optical resistive and piezoresistive strain gauges may be coupled to the detector bar as well as enhanced mechanical and electrical components. Optional equipment including an optical sensor, and pulse and frequency modulators improve noise immunity and reduce power consumption.

Abstract: A method and apparatus for controlling the amount of lubricant dispensed in a railway lubricating system wherein a test cycle is effected during which lubricant is dispensed in a test amount to detect the influence of lubricant viscosity on the system, and wherein further dispensing cycles are effected to sequentially dispense an accurate and desired amount of lubricant in conformity with the detected influence of lubricant viscosity.
