Systems and methods are disclosed that operate a door latch of a door of a heating, ventilation, and/or air conditioning (HVAC) system electronically based on operating a locking engagement device. The locking engagement device may be disposed on an outer portion of a door, the latch may be part of a latching system disposed on an inner portion of the door, and the locking engagement device may transmit a signal indicating that the locking engagement device is in an open or closed position to the latching system via a conductor electronically coupling the locking engagement device and the latching system. In some embodiments, the locking engagement device may transmit a signal indicating that the locking engagement device is in an open or closed position to a controller, which may then instruct the latching system to open or close the latch based on receiving the signal.

A drawer assembly is described that includes one or more mini-drawer assemblies. A mini-drawer assembly comprises a sliding tab along a rear-to-front axis, a release mechanism coupled to the sliding tab, and a body having a body bottom coupled from the body bottom to the sliding tab. The body may slide over the sliding tab. The mini-drawer assembly may include a plurality of compartments in the body and a plurality of lids that are hingedly coupled to the compartments. Each lid may have a respective fastening element. A plurality of latches may couple to the body such that each latch is coupled to a corresponding compartment. The latch may hold the respective fastening element of the lid. When the body is pulled out along the rear-to-front axis, the release mechanism may engage with the latch to release the respective fastening element and to unlatch the lid of the compartment.

A locking system and method of manufacture can include: a cargo container having a first container door, a second container door, and a container frame base; a lock box affixed to the second container door, the lock box extended into and through the second container door, the lock box including a sliding lock rod configured to extend behind the first container door when the lock box is in a locked configuration; a sliding lock rod guard affixed to an exterior surface of the first container door and affixed to the exterior surface of the second container door; door guards affixed to the second container door and the first container door; and a drop lock affixed to an interior surface of the first container door, the drop lock including a drop lock rod configured to extend down into the container frame base when the drop lock is in a locked configuration.

Provided is a method, performed by an access authorisation verification apparatus, involving the steps of: obtaining a piece of information from a transmission; identifying a transmission data record using the piece of information obtained from the transmission, wherein the transmission data record comprises address information associated with the transmission; determining an access control apparatus on the basis of a comparison of the address information of the transmission data record with respective address information that is associated with the access control apparatuses and stored on the access authorisation verification apparatus; allowing selection and/or confirmation of an access control apparatus for the determined access control apparatus by a user of the access authorisation verification apparatus; and communicating access authorization information to the access control apparatus in order to gain access to a room associated with the access control apparatus, so that the transmission can be placed into or removed from the room.

A system and method for automatically screening anyone arriving to a facility outside of predetermined entry and exit times is provided. The automated screening system denies entry and detains anyone determined to be a threat. An operator may then take the person denied entry into custody or manually override the system to allow the person access to the facility.

A locking system is mounted to a door with three rods extending therefrom. The rods have a locked position extending beyond the periphery of the door and an unlocked position not extending beyond the periphery of the door. Three rod receivers are adapted to receive the three rods in the locked position. A handle rotatably engages cam plates which are operatively engaged with the rods whereby rotation of the handle rotates the cam which moves the rod ends from one position to the other. A locking tab extends forwardly from the lower cam plate into a recess and is engaged by a circular lock while the recess prevents movement of the engaged circular lock. A second locking tab extends forwardly from the rod-locking link and a stationary locking tab is aligned thereto. Both locking tabs are engaged by a padlock preventing movement of the rod-locking link.

A locking system provides multiple lockable latching mechanisms that are collectively operable and lockable from a central actuation mechanism. Each latching mechanism can be positioned and actuated independent of the positioning of others of the latching mechanisms. In particular, the latching mechanisms need not be aligned with one another. The system uses flexible connectors between the central actuation mechanism and the respective latching mechanisms. The flexible connectors can have different respective lengths.

A locking device intended to prevent opening of a door/doors includes a body (2), which is capable of being coupled immovably to a door handle and prevents opening of a door/doors. The body is provided with a coupling arrangement adjustable with adjustment elements for locking the handle against an external surface of the door by being propped immovably on a vertical frame member of the door or on a handle of the adjacent door.

A smart entryway includes an entrance door assembly configured to allow users (e.g., residents) to enter and exit a first space (e.g., a residence) and a storage assembly configured to allow secondary users (e.g., deliverymen) in a second space (e.g., a porch) to store items for later retrieval by the users. A portion of the storage assembly may be optionally refrigerated or heated. A security assembly is provided between the entrance door assembly and the storage assembly. The security assembly includes an authentication device to authenticate users and secondary users and a locking device to unlock the storage assembly and the entrance door assembly upon authentication. The locking device is provided behind the authentication device and concealed from the second space. When a first door of the storage assembly accessible from the first space is opened, a second door of the storage assembly accessible from the second space is locked.
