Abstract: Provided is a rearwardly-pivoting door having a pivoting arc in the longitudinal direction of a vehicle. The door may be pivotally coupled with the vehicle by a hinge assembly at a rear portion of the door and a front portion is slidably engaged in a channel receiver when the door is in a closed position. The hinge assembly and channel receiver resist lateral movement of the door to maintain an occupant within a seating area of the vehicle. One or more securing devices may be utilized to maintain the door in an opened or closed position. The securing device may be mechanical and/or magnetic.

Abstract: A weight-measuring system for measuring a weight amount of one or more items loaded into a bed of a vehicle is provided. The weight amount can be used to determine whether a weight limit has been exceeded and whether some additional action should be taken. In addition, one type of weight-measuring system is operable under varied conditions, such as rapid weight fluctuations, and is capable of measuring a weight amount when the bed is in various positions (e.g., transporting mode or ground-level, loading mode).

Abstract: An improved liquid infiltration adapting structure for preventing liquid infiltration around a gate valve box. The structure has an annular tube structure that is tapered to more easily receive a mating pipe. The tube structure may also comprise at least one bead for further securing the mating pipe. The adapting structure is also improved by providing a stepped inner flange for ease of installing the structure around the gate valve box.

Abstract: A gate valve box adaptor structure, the present invention provides a permanent support for the key box bonnet that is unaffected by the surrounding environment. The adaptor is supported on the gate valve to a positive location for the key box bonnet at a level which prevents infiltration of soil and moisture into the bonnet. The adaptor is provided with a resilient gasket of a unique design to provide a cushion and to create a seal for the bonnet on the gate valve. A plurality of liquid infiltration prevention structures for preventing liquid infiltration into manhole assemblies.
