A parcel-lock system and methods for securely receiving delivery items or parcels. The system has an electronically controllable parcel-lock on a door of an enclosure. The parcel lock stores one or more unlocking codes such as QR codes or barcodes. When the parcel lock receives an access code matching one of the unlocking codes, the parcel lock unlocks the door to allow the deposition of the delivery items, and starts video-recording using a front and a rear camera thereof. The parcel lock also continuously plays a beeping sound during the time the door is open.

A lid system includes: a lid for a vehicle, the lid being configured to be opened when the vehicle is supplied with energy; a lid locking device for the lid; a control device configured to control the lid locking device; and a switch operable by a user. When the switch is turned on, the control device interlocks a locked state and an unlocked state of the lid locking device with a locked state and an unlocked state of a door locking device for a door of the vehicle. When the switch is turned off, the control device does not interlock the locked state and the unlocked state of the lid locking device with the locked state and the unlocked state of the door locking device.

A sash window restrictor (20) has a housing (22) which is to be let into a vertical frame member (10) of one sash (normally the upper, outer sash) of a window, at a position, say, 10 cm above the top rail of the lower sash when the windows are closed. A tab (24) is mounted in the housing and can be retracted into the housing or extended from the housing. A mechanism acts between the tab and the housing and allows the tab to be pressed into the housing and held in the housing for a period of time before the tab is released to allow the tab to extend. With the tab extended, the lower sash (12) can be lifted until it reaches the tab (24) but no further, so that a 10 cm gap will be opened at the bottom of the window.

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 method for mutually controlling and unlocking a dual plug in a lock, comprising: unlocking a code of a first plug first, the first plug restricting unlocking of a second plug, the second plug restricting rotating of the first plug before the code of the first plug is unlocked; after unlocking the code of the first plug, the first plug translating to a second position from a first position using a preset position difference, the first plug being unable to rotate during the translation; after moving the first plug to the second position, the first plug releasing a restriction on the second plug, the second plug still restricting the rotating of the first plug; and unlocking the code of the second plug, the first plug and the second plug being able to rotate synchronously so as to unlock the lock after unlocking the code of the second plug. The present invention further relates to a lock with a dual plug.

A lock is provided for a secondary aircraft cockpit barrier. The lock has a locking tongue, a cavity for receiving the locking tongue, a locking retainer for retaining the locking tongue in the cavity, and a damped locking tongue releasing mechanism for releasing the locking retainer thereby unlocking the locking tongue from the cavity. The damped locking tongue releasing mechanism is damped such that releasing the locking retainer requires at least about 5 seconds.
