Abstract: An electronic height control system for a vehicle chassis air suspension is modified to provide bimodal operation. In the second mode of operation the chassis air suspension system is maintain a stationary in a stable, level position to serve as a base for a mobile aerial lift unit installed on the vehicle. Operation of the suspension system in its stabilization and leveling mode is triggered by activation of a vehicle power take-off unit (“PTO”) used to position the aerial lift unit.

Abstract: A sensing device mounting mechanism, and related method of operating such a mechanism, are disclosed. In at least some embodiments, the mechanism can include a housing that is mountable to a support structure. The housing can define an interior for receiving and supporting a sensing device. The mechanism further includes light pipe device coupled to the housing. The light pipe device can be used to communicate light from a light source to the sensing device, or from the sensing device to a location exterior of the housing such that it can be viewed, detected or received by an operator or other device. Advantageously, the sensing device mounting mechanism is constructed so as to enhance and facilitate, as opposed to interfere with, proper performance of the sensing device.

Abstract: A hydraulic vehicle power take off system is implemented using modular components and utilizing a vehicle controller area network for integration with vehicle systems. The modular components are preferably in turn adapted from standard industry components.

Abstract: An hybrid four wheel drive system characterized by a vehicle having a conventional rear wheel driveline as well as a conventional driving front steer axle powered by an hydraulic motor. The hybrid four wheel drive system is provided in multiple embodiments, particularly with and without an hydraulic pressure accumulator.

Abstract: Radio remote control over a motor vehicle and particularly of auxiliary systems installed on the vehicle is effected through an onboard controller which is integrated with the vehicle's controller area network. This arrangement increases flexibility of the system for handling different systems, and potentially more than one unrelated system.

Abstract: Solenoid controlled hydraulic valves in sealed hydraulic circuits are provided with backup actuation without compromise of the hydraulic circuit by provision of an auxiliary, quick fitting solenoid coil case which incorporates manual switches and which may be attached directly to a battery for energization.
