Abstract:
A light apparatus for use with a power source and a control switch, the control switch including an input node, an output node and at least first and second independently selectable current paths between the input and output nodes, the first selectable current path having a resistance value that is greater than the second current path, controlling light intensity as a function of which of the current path is selected, at least one light source, a controller linked to the control switch and determining the selected path and generating a control signal and a light driver linked between the output node and the light source, the driver receiving the control signal and adjusting the current applied to the light source as a function of the control signal.

Abstract:
A satellite positioning location based control and monitoring system for light rail transit systems which enables transit personnel to track vehicle positions, progress and non- vital signals as light rail vehicles travel through their routes while eliminating the capital and maintenance costs associated with embedded light rail transit monitoring systems.
Abstract:
A locomotive air brake control system that responds to penalty braking requests from external systems by applying a varying amount of train brake level based on monitored and calculated parameters in order to enforce a defined train condition. The system may include a minimum acceptable train braking, a condition to be achieved to prevent further application of train brakes, and a maximum train brake level to be applied in response to the request. Alternatively, the system may apply braking in stepped levels according defined thresholds for a train behavior variable of interest such as speed or deceleration. The system may be configured to incrementally apply and release train brakes during the adaptive penalty, and may also adjust the level of braking according to calculated braking capacity of the train.
Abstract:
This disclosure relates to a system configured to detect rail vehicle events. Some or all of the system may be installed in a rail vehicle and/or be otherwise coupled with the rail vehicle. In some implementations, the system may detect rail vehicle events based on pre-determined rail vehicle event criteria sets. The system may include one or more sensors configured to generate output signals conveying information related to the rail vehicle. In some implementations, the system may detect rail vehicle events based on a comparison of the information conveyed by the output signals from the sensors and/or parameters determined based on the output signals to the pre-determined rail vehicle event criteria sets.
Abstract:
