Abstract: The invention provides an apparatus, system, and method for enabling the installation of an installable device configured with a required component in a receiving device. A component deactivated interlock obstructs the installation of the installable device when not configured with the required component. The invention makes use of an extendable and retractable plunger disposed upon the installable device, a stop barrier disposed upon the receiving device, and an actuator disposed upon the required component. The plunger normally extends beyond the installable device, and upon contacting the stop barrier of the receiving device obstructs the installation. Upon a physical connection of the required component with the installable device, the actuator retracts the plunger, thereby enabling the installation of the installable device.

Abstract: A system is provided for comparing an input query with a number of stored annotations to identify information to be retrieved from a database. The comparison technique divides the input query into a number of fixed-size fragments and identifies how many times each of the fragments occurs within each annotation using a dynamic programming matching technique. The frequencies of occurrence of the fragments in both the query and the annotation are then compared to provide a measure of the similarity between the query and the annotation. The information to be retrieved is then determined from the similarity measures obtained for all the annotations.
