A locking system for a stop button employed in a mortise lock having a spindle for operating a latch utilizing a first spindle base and a second spindle base which are nested relative to one another. Each base includes an opening for the mortise lock spindle such that the spindle may enter the combined first and second bases from the left side or the right side. A locking hub overrides either the first or second base and is capable of selectively lying over either the first or second base. An abutment linked to the stop button interacts with the locking hub such that either the first or second base may not be turned by the spindle when this occurs. Locking hub selectively locks either the first or second base through its position relative to the same and allows the mortise lock to easily transform from a left-hand version to a right-hand version.

An electronic lock includes a compression spring that stores energy to ensure that the electronic lock re-locked after unlocking. The spring is received between a lock bolt and a lock bolt housing. When the electronic lock is locked, the lock bolt is received in a notch of a locking portion. When the electronic lock is unlocked, a motor moves both the lock bolt and the lock bolt housing in a direction to remove the lock bolt from the notch. After a predetermined amount of time, the motor is reversed to move the lock bolt housing in an opposing direction. If the outside handle has not been released, the lock bolt does not re-enter the notch. The spring is compressed between the lock bolt housing and the lock bolt and stores energy. When the outside handle is released and the notch returns to the original position, and the spring pushes the lock bolt into the notch to ensure the electronic lock is re-locked.

A lock assembly includes a single switch actuated by a cam for monitoring the position of a main bolt and an auxiliary bolt. The main bolt and the auxiliary bolt engage and move the cam between an actuated position and a released position. In the actuated position the cam actuates a switch. Actuation of the switch indicates that the auxiliary bolt is retracted and that the main bolt is extended into a locked position. The main bolt includes a tail that engages a portion of the cam to drive the cam to the actuated position. The switch will remain in the actuated condition when the auxiliary bolt is retracted and the main bolt is also retracted.

An electronic lock assembly is actuated by a key including a transponder. The key is received within a coil assembly of the lock assembly. The key engages a switch that powers the coil assembly. The coil assembly generates a magnetic field that energizes the transponder. The transponder transmits a signal received by a controller. The controller actuates the lock assembly responsive to the received signal to move a locking member to an unlocked position. The key may then move to unlatch a latch associated with the lock assembly. As the key provides the energy required for unlatching the latch further energization of the motor is not required. The lock assembly provides for the actuation and energization of the transponder with small amounts electrical energy such that the lock assembly may be powered by commercially available batteries for a practical operational life.

A combination lock includes various features that make the lock manipulation-resistant. The lock has a rocker arm with a curved underside section that contacts a roller on a cam that rotates when the lock dial is rotated. The smooth curve and an angled contact portion on the rocker arm causes the force applied to the rocker arm by the roller to be gradual rather than abrupt, ensuring that the contact point between the rocker arm and the roller is unpredictable. The lock may also include various spring-biased relocking devices that are biased away from the travel path of the bolt when the back cover is attached to the housing. The biasing force in the relocking device causes the device to move into the travel path of the bolt when the back cover is displaced or removed, preventing the bolt from moving to an unlocked position. The lock may also include a toothed washer having a trapezoidal tooth and a corresponding trapezoidal notch in a tube in the lock housing to eliminate transfer of rotation from one wheel to another. The trapezoidal shapes eliminate air gaps between the tooth and the notch, tightening the dial span of the lock.

A lock programmer/interrogator assembly for communicating with an electronic lock. The assembly includes a key comprising a circuit card having surface contacts positioned to align with contacts in an electronic lock smart card reader when the key is inserted into a smart card reader module. A cable connector is mounted on the circuit card. The circuit card includes current paths that electrically connect the surface contacts to pins of the cable connector. The assembly also includes a cable connectable at a first end to the cable connector and at a second end to a computer. The cable includes wires connectable between the pins of the cable connector and the computer.

A system and method for defining a schema and sending a query to a similarity search engine to determine a quantitative assessment of the similarity of attributes between an anchor record and one or more target records. The similarity search engine makes a similarity assessment in a single pass through the target records having multiple relationship characteristics. The similarity search engine is a server configuration that communicates with one or more database management systems for providing data persistence, data retrieval and access to user defined functions. The architecture enables search activities to be segmented among multiple remote database management systems for reducing the time required to perform searches. Implementation provisions include a method by which a secure transport driver may be configured for a datasource and a method by which configuration files may be persisted to either filesystem storage or a relational database.

The invention provides a classification engine for classifying documents that makes use of functions included in a similarity search engine. The classification engine executes a classify command from a client that makes use of similarity search results, and rules files, classes files, and a classification profile embedded in the classification command. When the classification receives a classify command from a client, it retrieves a classification profile and input documents to be classified, sends extracted values from the input documents based on anchor values to a XML transformation engine to obtain a search schema, requests a similarity search by a search manager to determine the similarity between input documents and anchor values, and classifies the input documents according to the rules files, classes files, and the classification profile. The client is then notified that the classify command has been completed and the classification results are stored in a database.

A method for tracking user access to electronic mortise locksets includes providing electronic mortise locksets that each include a locking bolt that a lock-out mechanism blocks against retraction until a lockset controller disengages the lock-out mechanism in response to a key reader identifying a properly configured key. Each lockset controller is programmed to upload access data to a key memory whenever a properly configured key is used to unlock the electronic mortise lockset by inserting the key into a key reader of the lockset. The access data stored in the key memory includes a record of the times that the key is inserted into each of the locksets.
