Abstract: Described are system and methods in which the speed of a service vehicle and the configuration of an extendable service component of the vehicle may be monitored. The vehicle can be driven with the extendable service component out of its home configuration as long as the speed is below a speed threshold. However, if the speed of the vehicle exceeds the speed threshold while the extendable service component is out of its home configuration, an extended service component alert signal is transmitted. Although a local alarm may (also) be provided to the vehicle operator, the extended service component alert signal is transmitted wirelessly and provides one or more alerts on at least one receiver remote from the vehicle, such as on a mobile phone of a supervisor who can take action. In some embodiments, the speed threshold may vary depending on the location of the vehicle.

Abstract: Systems and methods for reporting a position of an air-over-hydraulic road treatment element use pneumatically activated switches triggered by pilot air for moving the road treatment element. Switch activation electrical signals are used to determine whether the road treatment element is in an engaged configuration or a disengaged configuration. If the switch activation electrical signals indicate the engaged configuration, an engaged configuration electric signal can be maintained until the switch activation electrical signals indicate the disengaged configuration. Conversely, if the switch activation electrical signals indicate the disengaged configuration, a disengaged configuration electric signal can be maintained until the switch activation electrical signals indicate the engaged configuration.
