In one embodiment, an electronically controlled hatch system for safe ingress, egress, hazard detection, and methods thereof are provided to reduce or eliminate hazards to personnel, including protection of people above and below a scuttle hatch, access port, skylight or elevated deck. Said hatch system reduces the risk of falls while ascending or descending a ladder through an access port. In certain embodiments, severe weather, hazard, security, and other safety information are detected and transmitted to a central control unit for processing and regulating the opening and closing of a hatch covering the access port and/or raising and lowering a safety railing system based on said information and/or user input. Said hatch system may include an actuator and guides for automatically locking/unlocking and opening/closing a hatch, an actuator and guides for automatically raising/lowering a railing system, safety monitoring detectors/apparatuses, and a centralized controller.

A door lock apparatus, comprising a male component; a connection to a power source; a lock actuator, powered by the power source and configured to move the male component at least partially through a strike and into a box beyond the strike in the path of the male component to lock a door, wherein the male component comprises a plurality of parallel subcomponents oriented lengthwise in the direction of a path of the male component; a bed of sensors positioned in the box and configured to sense a number of parallel subcomponents that contact the bed after the male component has been moved into the box; and an alarm in communication with the bed, wherein the alarm is triggered when an attempt is made to lock the door and an insufficient number of parallel subcomponents contacting the bed has been sensed by the bed of sensors.

A modular bike lock includes a locking mechanism and a securement mechanism coupled with the locking mechanism. The securement mechanism wraps around at least a portion of a bicycle and includes a locking end configured to engage with the locking mechanism to lock the bike lock. The bike lock includes a wireless communications interface and a processor that receives, using the interface, a selection from a mobile device that indicates that the mobile device has selected to use the bike lock and communicates, using the interface, a unique identifier associated with the bike lock to the mobile device, the unique identifier enabling the mobile device to unlock the bike lock. The bike lock locks automatically in response to receiving the locking end within a portion of the locking mechanism without receiving an additional input from the mobile device. The bike lock is mountable on a support structure.

An electromechanical lock includes a lever coupled with a locking mechanism configured to receive mechanical power from an user, and to output the mechanical power to mechanically disengage the locking mechanism provided that a support of the fulcrum is in an open position, and a return mechanism for the support of the fulcrum including a reset spring whose other end is configured to, during the reception of the mechanical power from the user, move past the support of the fulcrum with the mechanical power outputted by the lever, and, finally, force the support of the fulcrum with the mechanical energy outputted by the return spring through the lever back to a locked position.

A wireless door lock power system includes a power transmitter configured to be coupled to a building power supply having a transmit face at or near a door jamb and a power receiver configured to be coupled to a door closably received in the doorjamb. The power receiver has a receive face at or near an edge of the door. The power receiver receives a wireless power transmission from the power transmitter. A chargeable battery is received in the door. The battery is electrically coupled to the power receiver. The battery receives power from the power receiver to recharge the battery. An electronic door lock is operably coupled to the battery. The electronic door lock has a lock electronically actuated to lock the door to the doorjamb.

An installation-free rechargeable access control system is disclosed which automates the action of locking and unlocking a single-cylinder deadbolt on a door. In various embodiments, the present teachings provide a portable electronic module that can enhance the usage of deadbolts in place, instead of replacing the deadbolt mechanism itself. In various embodiments, the access control system can authenticate users and rotate a deadbolt using one or more peripheral sensing sources and wireless protocols.

The present disclosure describes a method for operating a mailbox, the method comprising: detecting a motion in proximity to the mail box; engaging a lock based at least partially on the detecting of the motion; and disengaging the lock after a predetermined amount of time has passed after detecting of the motion, in the absence of detecting additional motion.

An electronic lock, including: a power storage device; and photovoltaic cells located on a surface of the electronic lock, the photovoltaic cells being electrically coupled to the power storage device in order to provide a charging current to the power storage device.

The embodiments presented within provide methods, devices, and systems that improve access control through the use of smart cylinder locks. In one embodiment, a smart cylinder may perform a process including receiving a key, emitting an energy source of electromagnetic radiation; detecting a change in the energy source due to a physical property of the key, determining the physical property of the key from the change in the energy source, comparing the physical property with a predetermined value, and engaging a mechanism operatively coupled to a locking device that allows the locking device to lock or unlock when the physical property matches the predetermined value.
