Abstract: A system for containing derailment of a railway vehicle from rails over which the railway vehicle moves. The derailment system includes a derailment apparatus provided on each side frame of the railway vehicle. In one instance, each derailment apparatus has inner and outer laterally spaced and free ended depending arms disposed above a head section of the rails as long as the railway vehicle wheels ride on the rails. In the event either wheel becomes derailed, one the rails is received and accommodated within a pocket defined by the respective derailment apparatus. When a derailment occurs, the depending arms of the derailment apparatus extend below and to opposed sides of the head section of a rail received and accommodated in the pocket of the respective derailment apparatus whereby inhibiting total derailment of the railway vehicle from the rails over which the railway vehicle is traveling.

Abstract: A system and method for managing a permit-based parking environment governed by a parking program. The permit-based parking environment includes a number of parking permits each including a unique RFID tag and tag number. One or more RFID readers are used to scan the vehicles parked in the parking environment to determine if a RFID tag is associated with the parked vehicle. The results of the scan along with information related to the parked vehicle are provided to a permit management system to determine if the vehicle is parked within the scope of privileges pre-defined for that vehicle, pursuant to the parking program governing the parking environment. The permit management system stores, manages, and monitors data related to the permits controlled under the parking program.

Abstract: A static pressure sensing probe has an aerodynamically shaped cross section, and extends laterally from an aircraft surface sufficiently so that an outer end of the probe is a short distance outside the boundary layer on the aircraft surface on which the probe is mounted. The probe has surface corrugations or ridges along the probe, and the ridges include an upstream ridge adjacent the leading edge, and a downstream ridge spaced rearwardly from the upstream ridge. The ridges cause pressure disturbances along the probe surfaces. Static pressure sensing ports are positioned on the surfaces of the probe relative to the ridges in regions of pressure disturbances caused by the ridges. The probes can be mounted on opposite sides of the aircraft and pneumatically or electrically connected to average the pressures from selected sets of ports.
