Abstract: An impact protection structure includes an impact frame and one or more impact bars connected to the impact frame through one or more impact buffers. The impact buffers are configured to linearly absorb an impact force over a predetermined displacement distance. The impact bars can include slotted holes for receiving hinge pins connecting the impact bars to the impact buffers. The impact frame can be connected to a vehicle frame in a manner that permits some deformation of the vehicle frame without deforming the impact frame. One or more sensors can be provided to detect impacts. An impact alert signal can trigger a drive-inhibit function that removes torque from the drive motor. A manual override can permit an operator to drive the vehicle during the drive-inhibit function until the drive-inhibit function is reset by authorized service personnel. Additional equipment can be retrofitted to the vehicle using the impact frame.

Abstract: A clamp comprises first and second clamp halves, each comprising an elongate object receiving portion and a portion of a clamp retention mechanism. The first and second elongate object receiving portions are sized and shaped to cooperatively hold an elongate object at a desired position when the first and second clamp halves are fastened together. The first and second portions of the clamp retention mechanism are sized and shaped to (a) engage each other when the first and second clamp halves are moved towards each other in a first direction, (b) fasten the first and second clamp halves together without requiring use of a tool to engage the retention mechanism, and (c) disengage from each other when the first and second clamp halves are moved away from each other in a direction orthogonal to the first direction to unfasten the first and second clamp halves without use of a tool.

Abstract: A modular assembly for a fuel-cell vehicle is configured to connect to a bracket arranged along a longitudinal frame of the vehicle. The modular frame can include one or more components for powering the vehicle, including one or more of a fuel cell, a battery, a battery cooling system, and hydrogen storage tanks. The modular assembly can communicate with the fuel-cell vehicle through standard integration components regardless of the particular components in the modular assembly. The modular assembly can be readily removed from the fuel-cell vehicle and replaced with a different modular assembly containing different components.
