The invention relates to a locking system comprising an electrically actuable mobile lock and an activation means that comprises a virtual key associated with the lock and that serves, on an interaction with a first mobile end device, to transfer the virtual key to the first mobile end device and to store it therein, with the virtual key serving to establish an encrypted data communication connection between the first mobile end device and the lock to couple the first mobile end device to the lock and to authorize the first mobile end device to actuate the lock. The invention further deals with a method of coupling a mobile end device to an electrically actuable mobile lock for the purpose of actuating the lock by means of the mobile end device.

A system includes a latch circuit configured to monitor a switch and to operate an electronic latch based on a position of the switch. The system also includes a power supply circuit configured to provide a first voltage level to the latch circuit during normal operations and a second voltage level to the latch circuit during power loss. The power supply circuit includes a primary power circuit configured to provide the first voltage level to the latch circuit and a plurality of supercapacitors configured to be charged by the primary power circuit and provide the second voltage level to the latch circuit.

Provided are a motor driving circuit, a control method therefor, and a driving chip. The motor driving circuit includes a logic module and a push-pull module, a channel selection module, an instruction recognition module, and an isolating switch module. An input signal is outputted by the logic module and the push-pull module to control the motor. The channel selection module is configured to select a channel for the input signal to make the input signal to be connected to the isolating switch module or the instruction recognition module, or disconnected. The instruction recognition module is configured to perform a corresponding operation on the isolating switch module according to an inputted instruction. The isolating switch module is configured to receive an instruction of the channel selection module and an instruction of the instruction recognition module to connect or disconnect the logic module.

A padlock is disclosed comprising an electronic circuitry and such that the padlock may be opened via a near field communication network such as Bluetooth or via other electronic interfaces such as an integrated fingerprint scanner. In one embodiment the padlock is capable of receiving and transmitting radio frequency signals from nearby sensor nodes containing information regarding temperature, humidity, moisture, speed, vibration, liquid level, concentration of gases and other sensing devices for use in a system for monitoring, tracking, tracing, alarms, access management, access recording, authenticity and integrity of goods, documents or other valued objects in storage or transit.

A door lock device includes a tongue pivotally engaged in a housing, a latch slidably received in the housing for latching the tongue to the housing, a sliding member located above the latch for forcing the latch to engage with the tongue, a follower slidably engaged in the sliding member and having a projection for moving the sliding member away from the tongue, a lever arm is pivotally attached to the housing and includes an end portion engaged with the follower for moving the follower up and down relative to the sliding member and the housing, a rotary member is attached to the housing and includes a stud engaged with the lever arm for rotating the lever arm relative to the housing, and a link is slidably engaged in the housing and connected to the rotary member.

Method and its enabling device for remote wireless micro-latching for security purposes, comprising at least one user or controller, one mobile communication device, and one secured device, whereas said user is enabled to open or close a micro-latch in said a secured device, for instant a safe box or a medical cabinet, allowing access to secured content, including money, ID card, checks, as well as medicine. Also disclosed is a multiplicity of said devices and their preprogrammed remote control by computer or mobile app. The micro-latching can be amplified to macro-latching, for instance by a micro-solenoid switching a high power electrical switch bank or relay, which in turn initiates industrial processes.

Some embodiments include a lock cylinder comprising: a plug assembly having a front portion and a back portion; a housing shell within which the plug assembly is rotatably disposed, wherein the housing shell includes a notch; wherein the back portion of the plug assembly comprises: a locking pin that is movably disposed, and wherein the locking pin is configured to prevent a rotation of the plug assembly when the locking pin is engaged in the notch and prevented from retracting by a multi-stable mechanism; and the multi-stable mechanism having at least two stable configurations corresponding to respectively to a locked state and an unlocked state, wherein the multi-stable mechanism can maintain the stable configurations without consuming energy; wherein, at a first stable configuration, the multi-stable mechanism prevents the locking pin from retracting, and, at a second stable configuration, the multi-stable mechanism enables the locking pin to retract.

A method and system of gaining authorized entry into a secure location is provided. The method includes providing an electronic lock having a dial, the lock operably coupled to a microprocessor having memory for storing a user input code and a valid code. The user rotates the dial to activate power to the lock and a first random character is generated. The user again rotates the dial until a first user input character displays in the display. The first user input character is stored in memory and a second random character is generated. After the user has entered all characters of the access code, the microprocessor compares the user input characters with the valid access code stored in memory and if it is an authorized code, an indicia is generated on the display to visually indicate to a user that the lock is capable of moving to the opened position.
