摘要： A solution including a noncontact electronic measurement device is provided. The measurement device includes one or more imaging devices configured to acquire image data of a surface of an object located in a measurement region relative to the measurement device and one or more projected pattern generators configured to generate divergent pattern(s) of structured light, which impact the surface of the object within a field of view of the imaging device when the object is located in the measurement region. Using image data acquired by the imaging device(s), a computer system can measure a set of attributes of the surface of the object and/or automatically determine whether the measurement device is within the measurement region. An embodiment is configured to be held by a human user during operation.

摘要： 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.

摘要： This disclosure relates to a system configured to identify geolocations in a rail network where rail vehicle events are likely to occur. In some implementations, the system may include one or more of a processor, a computing system, electronic storage, external resources, and/or other components. The system may be configured to illustrate the geolocations in the rail network where rail vehicle events are likely to occur on a map of the rail network, predict geolocations in the rail network where rail vehicle events will likely occur, generate coaching information based on the identified geolocations, and/or perform other actions.

摘要： A system for retarding the speed of a railcar comprises a brake; a hydraulic actuator moving the brake between a closed position in which the brake applies braking pressure on the wheel of a railcar, and an open position in which the brake does not apply braking pressure on the wheel of the railcar; a hydraulic circuit provided with a pump arrangement for supplying hydraulic fluid to the hydraulic actuator; and a control circuit coupled to the hydraulic circuit for controlling the flow of hydraulic fluid to move the brake between the closed and open positions.

摘要： A method includes obtaining creep measurements and tractive/braking measurements from at least one vehicle system at different locations along a route segment while the at least one vehicle system moves through the route segment. The method also includes calculating tribology characteristics of the route segment at the different locations. The tribology characteristics are based on the creep measurements and the tractive/braking measurements from the at least one vehicle system. The tribology characteristics are indicative of a friction coefficient of the route segment at the different locations. The method also includes determining an effectiveness of a friction modifier applied to the route segment based on the tribology characteristics.

摘要： Novel tools and techniques for monitoring railway track geometry. In one aspect, some such tools and techniques can determine a location of a platform along a railway, capture one or more images of the railway, and/or analyze the rail configuration at that point. In another aspect, some solutions might employ photogrammetric techniques to analyze the rail configuration and thereafter store data about the rail configuration, perhaps correlated with the location of the images, in a data store.

摘要： Systems and methods for a shuttle platform that is configured to allow a path for one or more passengers to load or unload from a light rail transit vehicle that runs on a shared track. The shuttle platform can move in a linear plane and may be operationally engaged with a drive system comprising, a drive component and a combination position lock and drive mechanism disconnect. The drive component may comprise a transfer component. The combination position lock and drive mechanism disconnect may comprise: a drive disengage latch; a secondary lock latch selectably alternatively engagable between strikers; a manual drive receiver simultaneously operationally engagable with both the drive disengage latch and the secondary lock latch, and comprising a manual drive work output operationally engagable with the manual drive work input; and an automatic release.

摘要： A lifting device for lifting a rail car includes a frame with a load plate movably disposed thereon and a back plate movably disposed on the frame and coupled to the load plate. The lifting device further includes a first actuator disposed on the frame and operatively coupled to the back plate and at least one second actuator operatively coupled to the load plate such that the first actuator and the at least one second actuator produce forces in first and second directions. Further still, the first actuator and the at least one second actuator move the load plate of the lifting device in a substantially vertical direction.
