Abstract: Disclosed herein is a flooring system comprising a foundation, a resilient layer overlying the foundation, a layer of resilient material overlying the resilient layer, a layer of rigid material including a channel overlying the layer of resilient material, an elongate laminated member disposed within the channel and secured to the layer of rigid material, a floorboard overlying the layer of rigid material and the laminated member, a fastener extending through the floorboard and into the laminated member to secure the floorboard to the layer of rigid material, and structure formed in the resilient layer for venting water vapor accumulating between the resilient layer and the foundation.

Abstract: A gyro system is disclosed in which the system is brought from an "off" position back to full operating speed and known orientation in a short time without requiring any external signal for orientation verification. A fast start procedure is disclosed in which the last known position is employed as the actual starting position of the gyro as well as an aligned procedure in which the last known position is employed as a reference point for faster alignment.
