DEVICE AND METHOD FOR RESPONDING TO LOSS-OF-BRAKE ON A RAILROAD CROSSING GATE MECHANISM
A crossing gate mechanism includes an electric brushless direct current (BLDC) motor with a sensing device, a crossing gate arm operated via the BLDC motor, a motor brake coupled to the BLDC motor, wherein the motor brake is configured to hold the crossing gate arm in a position, and a controller configured to control the BLDC motor, wherein the controller is configured to control the BLDC motor to raise or lower the crossing gate arm in response to a gate control signal, and wherein, when the motor brake fails to hold the crossing gate arm in the position, the controller is configured to control the BLDC motor to hold the crossing gate arm in the position instead of the motor brake.
Double-sided terminal board for grade crossing gate controller
A crossing gate mechanism includes a gate mechanism enclosure defining an interior space, external wires located substantially outside the gate mechanism enclosure, and a terminal board positioned within the interior space of the gate mechanism enclosure.

Shunt frequency check and transmit system
To locate a shunt, the shunt includes an RF transmitter configured to wirelessly transmit an identifier of the shunt such as the configured shunt frequency. The shunt may include switches or memory locations that may be configured by an installer to correspond to the configured shunt frequency. Other embodiments employ switches or sensors influenced by jumpers installed in the shunt to configure the frequency of the shunt. A portable device receives a transmission including the identifier and displays it along with an indication of the received signal strength of the transmission, and maintenance personnel move the portable device along the track to locate the highest received signal strength, which indicates the location of the shunt. The shunt may also include a test circuit that may be configurable to generate a test frequency, determine a parameter indicative of shunt performance, and output a signal based on the parameter.
USER INTERFACE FOR GRADE CROSSING GATE CONTROLLER
A crossing gate mechanism includes a gate mechanism enclosure, electrical components inside the gate mechanism enclosure, and a controller inside the gate mechanism enclosure. The controller is connected to and configured to monitor and/or control the electrical components. The controller includes an operator panel for receiving input from a user. In addition, the controller has a user interface displayed by the operator panel. The controller is operable to present information associated with the electrical components on the user interface.

GRADE CROSSING GATE ARM POSITION DETECTION SYSTEM
A crossing gate mechanism includes a swingable gate arm, a rotatable gate arm shaft fixed to the gate arm, and an electronic sensor assembly coupled to the gate arm shaft. Rotation of the gate arm shaft corresponds with swinging of the gate arm. The electronic sensor assembly senses an angular position of the gate arm shaft and transmits a position signal corresponding thereto. The electronic sensor assembly includes a driving element that is attached to the gate arm shaft to rotate therewith. the electronic sensor assembly also includes a driven element that is driven by the driving element such that rotation of the gate arm shaft causes the driven element to rotate. The electronic sensor assembly is configured to generate the position signal based on a position of the gate arm shaft.
