In one embodiment, an infrared (IR) imaging system for determining a concentration of a target species in an object is disclosed. The imaging system can include an optical system including an optical focal plane array (FPA) unit. The optical system can have components defining at least two optical channels thereof, said at least two optical channels being spatially and spectrally different from one another. Each of the at least two optical channels can be positioned to transfer IR radiation incident on the optical system towards the optical FPA. The system can include a processing unit containing a processor that can be configured to acquire multispectral optical data representing said target species from the IR radiation received at the optical FPA. Said optical system and said processing unit can be contained together in a data acquisition and processing module configured to be worn or carried by a person.

A door lock device is provided. The door lock device includes a panel and a mounting base. The panel is arranged opposite to the mounting base and is connected with the mounting base. The mounting base includes a recess located in a middle of one side of the mounting base and on a first surface of the mounting base close to the panel, and the recess and the panel form a handle structure.

The present disclosure provides a lock shielding structure having fingerprint module and a smart lock, the lock shielding structure having fingerprint module includes a cover for shielding a lock body, the cover comprises a rear plate and a front cover, a through hole is provided on the front cover, a fingerprint module is arranged in the through hole, a rear end face of the rear plate is equipped with an insertion shaft, a wire hole running through a front and a rear of the rear plate is defined on a position of the rear plate corresponding to the insertion shaft, and a wire in the lock body extends through the wire hole and connects to the fingerprint module. This not only saves volume, but also reduces holes in other parts, and makes the appearance more beautiful.

A key storage device for storing a key provided with an identification code, including a locking unit which has an unlocked state in which the key can be removed from the key storage device, and a locked state in which the key is locked in or on the key storage device. The key storage device includes a control unit connected to the locking unit and having a data interface, the control unit operable to read out the identification code of the key and to provide the identification code of the key at the data interface.

A system and method of authentication-based operation of a lock mechanism include detecting an authentication signal from an electronic authentication module, authenticating the authentication signal using a stored user profile, wherein the stored user profile is used for login authentication purposes and includes at least user data, and when the authentication signal is authenticated, activating an electromechanical mechanism to release a latch switch associated with a lock mechanism.

An opening and closing device is provided. The opening and closing device includes a housing, a displacement restricting part, an electrical driving module, and an electroless driving module. The displacement restricting part is capable of moving with respect to the housing when the electrical driving module is in an unlocked state. The electrical driving module is capable of restricting the displacement restricting part from moving with respect to the housing when the electrical driving module is in a locked state. The electroless driving module is capable of releasing the electrical driving module's restriction over the moving of the displacement restricting part with respect to the housing via the hand-driven part.

What is provided is a smart container cap device that can be unlocked remotely by a second device such as a smartphone or computer. The smart cap is sized and shaped to adhere to a standardized container lid sizing convention, such that the smart cap may be swapped for and replace a conventional container cap. The cap may also include sensors for detecting poor storage conditions (such as moisture or humidity) or tampering, or for a secondary means of granting access such as a biometric scan.

Systems and methods to indicate whether a safe is locked or unlocked.

A safe container comprises a first receptacle configured to receive a grooming product and a biometric lock configured to selectively open the first receptacle to a designated user. The grooming product may include a shaver and/or razor blade cartridges. The biometric lock may include a fingerprint reader.

A door handle includes a human body detection sensor, a controller, a servo assembly, and an engaging assembly. The controller is electrically connected with the human body detection sensor and the servo assembly, and the engaging assembly is controlled by the servo assembly. The engaging assembly includes a first engaging state and a second engaging state. When the engaging assembly is in the first engaging state, the door handle is able to drive a lock body connecting shaft to rotate; and when the engaging assembly is in the second engaging state, the door handle is unable to drive the lock body connecting shaft to rotate.
