This disclosure provides a lock having a rotating component, the rotation of which drives the retractable movement of a latch bolt, and the rotating component is equipped with a trigger component; a first sensing component, fixedly set or arranged at the first position of the lock, where the first position is the position indicated by a knob fixedly connected to the rotating component when the lock is in the unlocked state, and when the trigger component is at the first position, the first sensing component generates a first trigger signal; a second sensing component is fixedly set or arranged at the second position of the lock, where the second position is the position indicated by the knob when the lock is in the locked state, and when the trigger component is at the second position, the second sensing component generates a second trigger signal.

An electronic lock device includes a lock mechanism, an actuation mechanism that actuates the lock mechanism, and a control unit including a processor and a current detection module. During an operation in which the actuation mechanism is activated to start switching the lock mechanism from an original state to an intended state, the current detection module continuously detects an amount of electric current flowing through the actuation mechanism. When the amount of electric current is greater than a predetermined threshold, the processor controls the actuation mechanism to switch the lock mechanism back to the original state, and deactivates the actuation mechanism.

The present disclosure relates to a method for enabling a temporary user to gain temporary access to a locked space of a vehicle. The vehicle is configured to communicate with an intermediate system adapted to remotely control functionality of the vehicle. The intermediate system is configured to receive, from a user device associated with the temporary user, a request message to open a remotely operable lock of the locked space and further configured to, based on the request message, transmit an unlock message to the vehicle to open the lock. The request message from the user device includes access parameters to enable the lock to be unlocked, the access parameters received by the user device from a permission message transmitted by an owner device directly or indirectly to the user device.

A lock device includes a latch and inner and outer operating devices disposed on two sides of the latch device. The inner operating device includes a main board configured to control the outer operating device to or not to move a latch between the latching position and the unlatching position. The outer operating device includes a removable input interface module electrically connectable with the main board. The input interface module is configured to permit input of an unlocking identification information or an unlocking command by a physical or wireless measure.

A latch actuator comprises a motor, a speed reduction gearing coupled to an output shaft of the motor, a spindle, and a motion conversion mechanism. The spindle has a threaded portion in engagement with the speed reduction gearing. The spindle is supported to be rotatable about an axis. The threaded portion is rotationally fixed relative to the spindle. The motion conversion mechanism is configured to cause a displacement of the spindle along the axis when the spindle rotates.

A selectively operable door (50) for a robotic vehicle (10) may include a doorframe disposable in a barrier dividing two areas in which the robotic vehicle (10) is enabled to travel, a door body (54) hingedly connected to the door frame (52), and a latching assembly configured to alternately allow movement of the door body (54) such that the robotic vehicle (10) to enabled to pass through the selectively operable door (50) via displacement of the door body (54) and prevent movement of the door body (54) such that the door body (54) is retained in a closed state. The latching assembly may include an automatic lock configured to define a release position in which movement of the door body (54) from the closed state is allowed, and a capture position in which movement of the door body to the closed state is allowed and movement of the door body from the closed state is prevented.

A lock management system manages access to a controlled environment by locking or unlocking a door. The lock management system can actuate one or more components of a lock system to lock or unlock the door. To determine whether to lock or unlock the door, the lock management system can establish a connection with one or more devices. The lock management system can receive an access credential via the connection and authenticate the access credential. Based on authenticating the access credential, the lock management system can lock or unlock the door. The lock management system can monitor a door status and/or door activity and provide alerts to a user computing device.

A system and method for securing individuals within a bathroom until they have washed their hands is described. An electronic magnetic lock installed to the door of the bathroom, which is linked to a switch integrated into a faucet of a sink of the bathroom, prevents individuals from exiting the bathroom until the faucet is activated. Signage present within the bathroom informs individuals of the presence of the system, and an audible message, configured to automatically play over at least one speaker further informs them of the system, and reminds them to wash their hands in order to facilitate an exit of the facility.

A locking system for a temperature-controlled container is provided. The container has an interior and a barrier having an open position allowing access to the interior of the container and a closed position blocking access to the interior of the container. The locking system includes a temperature sensor for sensing a temperature within the container; a locking device coupled to the barrier to lock the barrier in the closed position; and a controller in communication with the locking device and the temperature sensor. The controller receives the sensed temperature from the temperature sensor and controls the locking device based on the sensed temperature. The controller is configured to control the locking device to lock the barrier in the closed position when the sensed temperature rises above a predetermined threshold temperature.

A knife holder for holding a knife includes a block defining a cavity to receive the knife, and a casing removably arranged inside the cavity and adapted to be locked with the block. The knife is removably arranged inside the casing. A lock structure locks the casing with the block to prevent the removal of the casing from the cavity. Moreover, a switch is adapted to be actuated by a user to enable an unlocking of the casing from the block to enable a removal of the casing from the block. A near field communication device is configured to determine a presence of an authorized user in a vicinity of the knife holder and facilitates an unlocking of the casing from the block in response to an actuation of the switch in the presence of the authorized user in the vicinity of the knife holder.
