A barrier control system running a program thereon, the barrier control system including a main body, a control unit disposed within at least a portion of the main body to execute the program to control operations of the main body, and at least one control device connected to the control unit to control operations of the main body through the control unit based on the program.

Systems and methods for control of a locking system are disclosed. In some embodiments, a system comprises one or more sensors configured to generate output signals indicating one or more movement information of a subject. The system comprises at least one processor operatively connected with the one or more sensors, and memory storing instructions executable by the at least one processor, the instructions when executed cause the system to determine, using the output signals from the one or more sensors, one or more movement parameters of the subject; and send, based on the determined movement parameters of the subject, an instruction to the locking system to adjust an open delay time for the locking system, the open delay time being time the locking system remains open.

A method for unlocking the lock using real-time wireless power supply includes proceeding with authentication identification of a powerless lock by an electronic key after pairing. Power is wirelessly supplied from the electronic key to the lock when the authentication identification starts or the authentication identification passes. The lock obtains the power wirelessly supplied from the lock to operate. When the authentication identification is identified as being successful, the electronic key outputs an unlocking command to the lock. The lock receiving the unlocking command proceeds with an unlocking operation using the power supplied wirelessly.

The Uninterruptible Timed Electromagnetic Locking mechanism consists of a rechargeable DC battery pack wired in parallel downstream of the power supply, a logic circuit including a programmable timer relay which when activated by a switch, engages the lock for a user-set amount of time regardless of future switch states, and an electromagnetic lock controlled by the logic circuit and programmable timer relay.

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 parcel-lock system and methods for securely receiving delivery items or parcels. The system has an electronically controllable parcel-lock on a door of an enclosure. The parcel lock stores one or more unlocking codes such as QR codes or barcodes. When the parcel lock receives an access code matching one of the unlocking codes, the parcel lock unlocks the door to allow the deposition of the delivery items, and starts video-recording using a front and a rear camera thereof. The parcel lock also continuously plays a beeping sound during the time the door is open.

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 method having the steps of obtaining temporal information communicated to a first device; carrying out one or more of the following tests: a test to determine whether the first device is in a state following an initial operation, a battery replacement or other power outage, or a reset, a test to determine whether a deviation between temporal information of the clock and the communicated temporal information is less than or equal to a threshold which is specified, and a test to determine whether the communicated temporal information has the same date as the temporal information of the clock; and synchronizing the clock using the communicated temporal information if all of one or more defined conditions are satisfied, wherein one of the one or more conditions requires that at least one of the one or more tests carried out has a positive result.

A domestic appliance (for example, a microwave oven), comprising: a housing; a front door; a retention mechanism (for example including a latch), located within the housing and engageable with the door; wherein the retention mechanism is movable between a first configuration, in which the door is retained in a closed position, and a second configuration, in which the door is non-engaged; an electromechanical actuator (for example a relay), adapted to move the retention mechanism out of said first configuration; and a controller (for example a microprocessor coupled to the relay, the microprocessor being operable in responsive to one or more signals to activate the relay, and thereby release the door from the closed position. Under spring bias, the door thus opens to about 30-45 degrees. The microprocessor-controlled door opening may be operable in three or more modes, including: actuation of a touch switch, remote control, or a microwave end of cooking.

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.
