A concealed asset locator includes an enclosure with multiple external surfaces, wherein an external surface is configured as reflective surface, an electric notification device, a receiver relay positioned inside the enclosure and electrically coupled to the notification device, wherein the receiver relay is configured to activate the notification device in response to a received transmitter signal.

A fixed signage (10) and method for use of the same are disclosed. In one embodiment, a housing (22) having a window (24) is sized to house a sign (26) therein. A closure assembly (32), under the power of an actuator (112), is installed in the housing (22) to support a cover material (34). The cover material (34) is moveable by a moveable closure member (138) between a fully retracted position whereat the cover material (34) is contained within the housing (22) such that the window (24) is exposed to a fully extended position whereat the cover material (34) covers at least a portion of the window (24). A command signal (180) may be received via a transceiver (160) to remotely control the actuator (112) and cover material (34). A signal sensor (60) within the housing (22) indicates the location of the cover material (34).

A railroad sign holder. The railroad sign holder provides a device for securing to a rail to display a signage member to oncoming trains and surrounding individuals. The railroad sign holder has a rod member, and a base member, the base member including an elongated section. The rod member has a signage member. The elongated section includes a rail clamp configured to removably affix to a rail. The rail clamp has a first arm and a second arm, each arm slidably disposed to a clamp bolt. Each of the first arm and the second arm includes a channel, the channel of the first arm facing the channel of the second arm. Each of the channels configured to receive a flange of the rail.

A system comprises a first sensor on a first end of a vehicle and an on-board controller coupled to the first sensor. The first sensor is configured to detect a radio frequency (RF) signature of a marker along a guideway. The first sensor is a radar detection device. The on-board controller is configured to determine a first position of the vehicle on the guideway or a first distance from the position of the vehicle to a stopping location along the guideway based on at least the RF signature received from the first sensor. The marker is a metasurface plate comprising a first diffused element, a first retroreflector element, a first absorbing element and a second diffused element between the first retroreflector element and the first absorbing element.

A positioning and odometry system includes two or more vehicle beacons installed on an end of a vehicle and configured to communicate with one or more guideway beacons installed along a guideway. Processing circuitry is configured to communicate with the one or more vehicle beacons and perform at least one of: determine, before the processing circuitry enters a sleep state, a first vehicle position on the guideway; determine, after the processing circuitry wakes from the sleep state, a second vehicle position on the guideway; determine, after the processing circuitry wakes from the sleep state, any difference between the first vehicle position on the guideway and the second vehicle position on the guideway; determine a third vehicle position on the guideway using range measurements taken at configurable time intervals; and determine a vehicle speed where speed is measured as a change in the third vehicle position over time.

A method for determining a signal aspect representing the vacant or occupied state of a track section for a rail vehicle, in particular a maintenance or construction vehicle, on a CBTC track. In this case, the rail vehicle does not have an on-board CBTC device. In order to dispense with special hardware, an app on a smartphone initiates the following steps: A) photographing of a track beacon in the direction of travel, B) determining the ID (identification signature) of the track beacon, C) transmitting of the track beacon ID to a CBTC track control center and D) receiving of the signal aspect determined by the CBTC track control center for the track section starting with the track beacon.

The sign pole system disclosed simplifies the FRA requirement by incorporating many features into the sign pole system. The worker operating the pole can quickly raise the pole just by stepping on the lift bar. To lower the pole remove the required safety is done by stepping on the release footstep. The built in LED features will activate only when it is nighttime and when the pole is in the vertical position. The sensitivity to actuate the LED's is adjustable to compensate for night yard overhead lighting. A solar panel keeps the battery charged. When required a pad lock (lock out device) can be inserted into the foot step base to secure the sign pole system in the up position until deemed safe by the worker to remove the sign protection. Manually attaching a night time blue light is no longer required because the LED light is now built into the sign pole and is automatically actuated.
