A device for preventing unwanted opening of a locked enclosure includes a lock bolt moveable between a locked position and an unlocked position. A face gear is meshable with and rotatable by the worm gear between locking and unlocking positions when the worm gear is driven in the first and second directions, respectively. A blocker member is rotatable between first and second positions. A biasing member is operatively coupled to the face gear and the blocker member to bias the blocker member in a biasing direction. A sliding member selectively disengages the blocker member to allow the blocker member to rotate in the biasing direction. A lever arm is operatively coupled to the sliding member such that the lever arm is in the disengaged and engageable positions when the sliding member engages the blocker member in the first and second positions, respectively.

A method of gaining authorized entry into a secure location is provided. The method includes providing an electronic lock having a dial, the lock operably coupled to a microprocessor having memory for storing a user input code and a valid code. The user rotates the dial to activate power to the lock and a first random character is generated. The user again rotates the dial until a first user input character displays in the display. The first user input character is stored in memory and a second random character is generated. After the user has entered all characters of the access code, the microprocessor compares the user input characters with the valid access code stored in memory if the user inputted code comprises an authorized code an indicia is generated on the display to visually indicate to a user that the lock is capable of moving to the opened position.

An input authentication method includes a processing unit generating a lead code according to a predetermined character string, wherein the predetermined character string includes a plurality of randomly arranged characters, the lead code is composed of N characters selected from the predetermined character string, and N is a positive integer; displaying the lead code on an input interface; the input interface receiving a first input; and when the first input corresponds to the N characters of the lead code, the processing unit performing a predetermined operation.

A locking system includes an actuator for controlling actuation of a locking mechanism. An electronic control system controls the actuator. A directional input device is operable to receive directional inputs from a user where the directional inputs form an access code stored in a memory of the electronic control system and used for controlling the actuation of the locking mechanism.

The invention relates to a manually operable input device (1) having a sensor system (15) that comprises at least one rotary control knob (4) for detecting at least one movement characteristic variable. By predefining various movement patterns at the rotary control knob (4), various control commands can be generated. For this purpose, the input device (1) according to the invention comprises an evaluation unit (8) that compares the signal (13, 14) generated by the sensor system (15) with predefined rotational movement codes (C1-C16) and generates a code-dependent control command (16) if the predefined movement pattern or the corresponding signal (13, 14) matches a predefined rotational movement code (C1-C16).

The present invention relates to electronic and mechanical dual combination locks. In certain embodiments, electronic and mechanical dual combination locks include: a lock base, a spin dial, a spin dial cover, and a spin dial release conversion mechanism. The lock base includes a mechanical combination lock inside. An electronic combination lock is positioned inside the spin dial cover. The spin dial release conversion mechanism has a spin dial release positioned on the top of the lock base. The spin dial release is used by the user to switch the electronic and mechanical dual combination lock between the electronic combination lock and the mechanical combination lock. When spin dial release is placed in a first position, the electronic and mechanical dual combination lock becomes the electronic combination lock. When the spin dial release is placed in a second position, the electronic and mechanical dual combination lock becomes the mechanical combination lock.

An intelligent door lock system that permits both electronic and manual control of a deadbolt. The door lock system can include an inner bezel assembly, an outer bezel assembly, and a deadbolt assembly, where the deadbolt assembly can be coupled to the outer bezel assembly via a twist-lock feature. The inner bezel assembly also includes a puck assembly that seats within an inner bezel. The puck assembly can be retained within or released from the inner bezel via a latch assembly. The outer bezel assembly includes a display assembly that seats within an outer bezel. The outer bezel is coupled to a motor chassis assembly that includes a motor and gear assembly having a series of gears that translate movement of dial elements or a motor into movement of a bolt element between locked and unlocked positions.
