摘要： The present disclosure is a method and apparatus for protecting building-related elements from collision damages. The apparatus can be designed to withstand high-impact collisions such as those caused by errant operation of heavy equipment. The method and apparatus are intended to be applicable to buildings already constructed and do not have to be implemented or considered before or during building design. In one exemplary embodiment, the apparatus can protect downspouts of warehouse sprinkler systems from collision damage that could result in pipe eruption.

摘要： In one embodiment, a method includes determining, by a controller, a first wind direction relative to a first vehicle and determining, by the controller, a first wind speed relative to the first vehicle. The method also includes calculating, by the controller, an absolute wind direction relative to ground using the first wind direction relative to the first vehicle and calculating, by the controller, an absolute wind speed relative to the ground using the first wind speed relative to the first vehicle. The method further includes calculating, by the controller, a second wind direction relative to a second vehicle using the absolute wind direction and calculating, by the controller, a second wind speed relative to the second vehicle using the absolute wind speed. A front end of the first vehicle and a front end of the second vehicle face different directions.

摘要： A system and method for managing data lifecycles that can provide an adaptable data management system configured to optimize the lifecycles of data and the reliability of databases. The system can provide data management systems with the ability to attach, detach, and drop segments of data based on key partitions of the data objects to optimize database utilization. By including the key partitions to the data objects, the database including the data objects can now perform data management operations based on the key partitions. The system, based on the key partitions, can identify a location of the data object to attach row entries, detach row entries from the existing tables, and delete the detached row entries from the database altogether. The system can operate on any relational database management system.

摘要： A train simulator test set is disclosed that can be operably coupled to a railroad track to measure the resting impedance of that track circuit and simulate a train by varying the railroad track inductance over a set period of time. The test set can select the speed, direction, and number of trains to simulate. By applying a variable inductance on the railroad tracks, the test set can simulate a train moving at variable speeds toward and away from the island. The test set can apply inductances to the railroad tracks to simulate two or more trains moving in each direction of the tracks at the same time, along with multiple looks and routes. The train simulator test set can include simulation software to vary the parameters of the train simulation and couple a variable inductance on the railroad tracks.

摘要： A system and method for monitoring a roadway by comparing captured images to image inconsistencies caused by lost or unnecessary motion and for minimizing lost or unnecessary motion of an axle of a vehicle and filtering erroneous pulses of an electrical signal to generate a trigger signal to capture images is presented. The system enables the minimization of image artifacts causing distortion in an image. The system can take images of a target, compute an object pixel size of the image to ensure calibration of longitudinal measurements, and calibrate the rotary encoder with the camera of the machine vision system. The system can enable calibration of the locomotive components in the field to compensate for the misalignment of the machine vision system and provide safe travels.

摘要： A Railroad Tie Management System is disclosed that can provide an efficient and organized method of inspecting and auditing ties in a rail system. Tie mark files can be retrieved by a client from a server or database in operable communication with the client, and upon instantiation of an inspection process governed by the system, an inspection information table and tie grid can be generated. The tie grid can operable to receive commands from a user, and the inspection information table is operable to automatically increment and decrement fields contained within in response to changes within the tie grid. The tie grid can also be configured to incorporate data from tie scans and serve the data to the client in a useful and user-friendly manner.

摘要： In one embodiment, a method includes capturing, by a camera of an image capturing module, a first image of a target. The image capturing module and a drum are attached to a fixture and the target is attached to the drum. The method also includes determining a number of lateral pixels in a lateral pitch distance of the image of the target, determining a lateral object pixel size based on the number of lateral pixels, and determining a drum encoder rate based on the lateral object pixel size. The drum encoder rate is programmed into a drum encoder. The method further includes capturing, by the camera, a second image of the target while the target is rotated about an axis of the drum, determining a number of longitudinal pixels in a longitudinal pitch distance of the second image, and comparing the number of lateral pixels to the number of longitudinal pixels.

摘要： A wheel impact load detection system for detecting defects in wheel of railroad vehicles is presented. The system can receive data from sensors and/or a weather station to determine a maximum force applied to a rail, and subsequently calibrate the determined maximum force to account to environmental conditions. Additionally, the present disclosure can assign severity levels and generate alerts with the assigned severity levels, and such severity levels can facilitate the proper prioritization of the alerts. It is an object of the invention to provide a system for accounting for variable environmental conditions and/or variable rail tension in assigning severity levels to mitigate unneeded stoppage of railway traffic.
