A cooler access control system locks a cooler when occurrence of an event is detected that requires limiting access to the inside of the cooler. Examples of such events include the loss of power to the cooler for a predetermined period of time, the opening of the cooler door for longer than an allowed time, the loss of functionality of a temperature probe and others. In an embodiment, a service mode is supported wherein the door is left unlocked despite the occurrence of such an event, to allow a stocker or other personnel to leave the cooler door open while stocking the cooler with product.

A safety switch (2) with a latching unit (12), by means of which an associated actuator (3) is held in a latched position. The latching unit (12) has an opening (9) and a blocking element. In a latched position, the blocking element projects into the opening (9) and rear-engages an actuator head (8) of the actuator (3), which is in the latched position. The blocking element is held in the latched position by means of a positioning element with a setting force. When the actuator head (8) is inserted into or removed from the opening (9), the actuator head (8) pivots the blocking element out against the setting force.

Example implementations relate to a security system having an electronic lock including latch and security modules, to control access to electronic devices. The latch module includes a receiver, a handle, and a torque member rotatably coupled to the receiver and handle. The receiver includes a first recess, a second recess, and a lobe to releasably engage the electronic device within the first recess. The security module includes a tension spring, an actuator, and a lock member having a first pin and a second pin. The tension spring is coupled to the lock member to engage the first pin to second recess when the latch module is in a latched configuration, and hold the security module in a lock-in position. The actuator is releasably engaged to the second pin for rotating the lock member to disengage the first pin from second recess, and release the security module from the lock-in position.

The disclosure is an intelligent electronic lock. The intelligent electronic lock includes: an electronic lock shell, a wireless communication module, an instruction input device, the instruction input device is arranged on the electronic lock shell for instruction input, a processor, the processor is connected to the wireless communication module and the instruction input device is connected to receive and send signals, and the electronic rope.

A portable electronic lock has a lock body having a locking device and a closing hoop that is movable relative to the lock body between a closed position and an open position, wherein the closing hoop can be locked to the lock body by means of the locking device in the closed position. The lock at least has an electrical unit, an electrical energy source, a signal generator, and a control unit. The control unit is configured to monitor a charge level of the electrical energy source and to control the signal generator to output a charge level warning signal sequence in the form of the letter sequence “S-O-S” in accordance with Morse code if the charge level of the electrical energy source falls below a predetermined limit value.

A lock cylinder (110) is provided adapted to be installed in a lock (100) comprising a lock bolt (120) for driving the lock bolt. Said lock cylinder comprises a cylinder housing (200), and a revolving plug (115) comprising a rotor element (275) adapted to rotate with respect to the cylinder housing about a rotation axis (R) within a rotation support (510; 520), and a driving tooth (280) for the lock bolt comprising an engage portion (282) adapted to engage the lock bolt, said driving tooth being rotatable about the rotation axis together with the rotor element and being coupled to the rotor element in such a way the operative distance between the engage portion of the driving tooth (280) and the rotation axis (R) varies, while rotating about the rotation axis, as a function of the rotation angle of the rotor element (275) with respect to the cylinder housing (200). When the lock cylinder (110) is installed in the lock, said operative distance has one among a plurality of first values when the rotation angle of the rotor element belongs to a first angular interval (A I) corresponding to a position of the engage portion of the driving tooth that is proximal to the lock bolt (120); and said operative distance has one among a plurality of second values when the rotation angle belongs to a second angular interval (A2) corresponding to a position of the engage portion of the driving tooth that is distal to the lock bolt, each of said first values being higher than each of said second values. When the lock cylinder (110) is installed in the lock (100), the lock cylinder is located below the lock bolt along a first direction (y) substantially perpendicular to the rotation axis (R). the driving tooth (280) is slidingly housed within a seat (550) which is radially provided in the rotation element (275) and which defines at least one side opening of the rotor element (275) perpendicular to the rotation axis (R).—The driving tooth (280) is provided with at least one engage element (590) which protrudes from a side opening along a direction parallel to the rotation axis, and adapted to slidingly engage guide profiles (524, 620) provided on the rotation support (510; 520), said guide profiles (524, 620) defining for said at least one engage element (590) an overall guide profile having an eccentric shape arranged to support from below along said first direction said at least one engage element (590)

An apparatus for interacting with a latch of a door includes a contact component configured to make physical contact with the latch, an electrically-powered module, and a housing. The electrically-powered module is configured to move the contact component such that the contact component pushes the latch out of a bore of a door frame and into the door. The housing contains the electrically-powered module and the contact component, and is configured to fit within the bore of the door frame. The apparatus can also include a mounting plate attached to the housing, the mounting plate configured to mount the apparatus to the door frame such that the housing is disposed within the bore of the door frame.

The present disclosure provides a lock and a method and a system for controlling the lock. The lock may include an operation part, an action part, and a bolt. The action part may be configured to drive the bolt to move. The operation part and the action part may be connected to each other via a transmission connection. The transmission connection may be blockable.

An electronic lock with an electronic sensing arrangement to accurately sense relative positions of a bolt which mechanically locks a door, such as a door of an electronic drop safe, and to also sense an electronically controlled plunger which locks the bolt in place. The arrangement provides a mechanism for sensing a variety of mechanical malfunctions, as well as, potential fraud or tampering situations.
