The system of the present invention is comprises of one or more door lock units, a data exchange system, and a clerk user interface. The door lock units are mounted to the cooler doors and prevent the doors from opening to allow access to the alcoholic products without authorization. These door lock units include a mechanical locking mechanism, an identification scanner/reader, and a display. The door lock units receives power from a power supply (with a back up power supply standing ready) and communicates wired or wirelessly with a data server and router combination. The data server and router combination also communicates with a clerk user interface, which may be in the form of a tablet, smart phone, laptop, or other computing device.

Disclosed is an invention that relates to a breakage prevention type card key. A breakage prevention type card key of the present invention includes: a substrate part installed inside a case part, a key accommodation part connected to the substrate part and having a groove into which an auxiliary key part is inserted, a locking part located inside the key accommodation part and elastically pressurizing a side surface of the auxiliary key part stored in the key accommodation part to restrain the movement of the auxiliary key part, and a reinforcement part extended from key accommodation part and coupled to the case part and augmenting the rigidity of the case part located on both sides of the entrance of the key accommodation part.

An apparatus includes an enclosure, a central processing unit, a power source, a first distance measuring device, a first compressible member, and a first housing pin, where the central processing unit is electrically coupled to the power source and the first distance measuring device. A first end of the first compressible member is mechanically coupled to a first end of the first housing pin and a second end of the first compressible member is mechanically coupled to an inner surface of the enclosure. The first distance measuring device positioned at the second end of the first compressible member, where the first distance measuring device is configured to measure a first distance to the first end of the first housing pin. A first key pin of a key structure disposed in the enclosure, where the first key pin is configured to compress the first compressible member the first distance.

A security device for holding a phone, camera, tablet, smart watch or other valuable item so that it can be viewed and used by a person, without the valuable item being readily removed from the security device. The security device has at least two clamping elements to clamp an item on two sides and clamping means to draw the at least two clamping elements together to clamp the item.

Systems, apparatuses, and methods are provided herein for securing merchandise. In one embodiment an apparatus for securing merchandise comprises a locking mechanism limiting access to one or more items, one or more optical sensors configured to detect a plurality of wavelengths and an intensity associated with each wavelength from at least one light beam emitted by an optical key, and a control device comprising a control circuit and a memory device. The control device being configured to store a lock code comprising a plurality of wavelength values and a plurality of intensity values each associated with a wavelength value on the memory device and determine whether to release the locking mechanism based on whether intensities of each of the plurality of wavelengths detected by the one or more optical sensors match the lock code.

A method, computer system, and computer program product for using strain gauges to detect a state of a lock. The strain gauges may be disposed within a key or a key head sub-system. The key bank system may include receiving a first signal, comparing the first signal with first or second signatures, and determining state change of a lock when the first signal matches the first or second signal within a first or second threshold. The key bank system may include receiving a current state of the lock, where the state of the lock is the first state, and changing the current state of the lock to a second state, where the second state is opposite the first state. The current state of the lock may be displayed on a communication device and may be stored in a memory of a communication device or a memory of a server.

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.

The invention relates to a combination (1) of control cabinet keys (2), individual keys being situated in the same plane but extending at a fixed angle (x) relative to one another and connected via a common center part (4, 5). Due to the fixed connection between the keys, during handling, a torque may be applied to a key (2) that is used. For ease of handling, a first unit (E.sub.1) and a second unit (E.sub.2) of keys extending at a fixed angle (x) relative to one another are provided, all units (E.sub.1, E.sub.2) have their own center part, and the units are detachably connected at their center parts (4, 5), and/or the keys are rotatable relative to one another, but only in a respective predefined plane.

A vehicle card-type smart key that it includes a tact switch; and a touch input unit for sensing a touch from a user; and a control unit which performs an action related to the button input only when both a button input from said tact switch and a touch input from the touch input unit exist.
