Abstract: With an automobile having electric power windows a power drive control circuit includes a solid state on-off power solid state device such as a PNP transistor with a moisture content sensor element interconnecting two electrodes of the solid state device (the emitter and base of the PNP transistor). When the moisture content sensor element becomes moistened as by rain falling thereon its electric through path resistance lessens to thereby achieve bias to conductive state for the PNP transistor through conductive state to activate the window motor drive and close any vehicle windows from the open state.

Abstract: A device in which units being transported can be adequately secured for protecting those units from damage during shipment. A chock that engages and substantially conforms to the surface of the unit to be secured is utilized. The paperboard chock can be utilized in numerous ways. The paperboard chock can be used independently by inserting it between a rigid structure and the unit to be secured such that the chock actively engages both the unit to be secured and the rigid structure. Two chocks could be used together by inserting the chocks between two units to be secured such that the chocks actively engage the units and are flush with each other. Various alternative schemes of use can be utilized by inserting a cushioning means against the chock to apply pressure to the unit to be secured. The chock comprises contact elements and a support element. The contact elements actively engage the unit to be secured and are themselves attached to the support element.
