Abstract: An emergent cricothyrotomy guide and cradle positioned on and affixed to a human neck to secure an endotracheal tube within the trachea during an emergency cricothyrotomy. The emergent cricothyrotomy guide and cradle comprises a horseshoe cradle, a strap fastener, and a split inner locking mechanism and may be packaged in an emergency medical kit with a blade knife, a bougie, and an endotracheal tube. The strap fastener is operable to be tied around the endotracheal tube received within the horseshoe cradle, securing the endotracheal tube within the trachea relative to the emergent cricothyrotomy guide and cradle until a permanent airway can be established.

Abstract: An interlock for a disk drive unit having a handle and a camming arrangement responsive to pivotal movements for inserting and withdrawing the unit from a housing fixture. A solenoid is actuable to lock the handle when the unit is fully inserted. A sensor is adapted for sensing an interlock engagement between the solenoid armature and the handle. For removing the disk drive unit, a delay is interposed before retracting the solenoid armature to assure that the disk drive unit is fully stopped before the handle can be rotated for removal of the unit.
