  • Patent number: 7561034
    Abstract: A load warning system for use with a vehicle having a load-support portion, a frame, and a vehicle-support portion movably coupled to the frame. The system has an engagement portion mountable to the vehicle-support portion or the frame and is movable therewith as a unit. A load indicator is mountable to the other one of the vehicle-support portion or the frame, and is spaced apart from the engagement portion when in a first position. The load indicator moves to a second position and engages the engagement portion when the frame moves a selected distance in response to the load applied to the load-support portion. The load indicator provides a signal upon being moved to the second position. A warning indicator is coupled to the load indicator and provides an improper load warning to a user in response to the signal from the load indicator.

  • Patent number: 5159259
    Abstract: This power supply system for a D.C. electrical load, such as an illuminated sign, is normally energized by batteries. A central processing unit monitors the battery voltage and when it falls below a predetermined magnitude, the central processing unit then activates a starter motor which cranks an engine coupled to it. The central processing unit also actuates a valve and fuel pump to pass fuel to the engine. The engine drives an alternator which produces A.C. voltage which is then rectified by aa rectifier to recharge the batteries. When the batteries are fully charged the central processing unit stops the engine. The central processing unit employs a microprocessor chip to control operations of the system.
