A control system for construction machinery includes a smart key configured to store a plurality of authentication codes and activate any one of the authentication codes, and a plurality of construction machines including a plurality of smart key modules mounted thereon respectively, the smart key modules communicating wirelessly with the smart key and having respective registration authentication codes which match with the authentication codes respectively. The construction machine including the smart key module having the registration authentication code which matches with the activated authentication code is controlled by the smart key.

An electronic lockbox includes a latching apparatus that uses a rotary actuator with multiple positions to achieve multiple locking states. Multiple positions of the actuator are detected, using optical sensors. The locking mechanism includes an outer sleeve and an inner cylindrical barrel that are coupled with torsion springs. The lockbox has a shackle and a key bin that include latch pins which are retained by the inner barrel when in the locked state, and the barrel can be rotated to either release the shackle or to release the key bin that typically holds a building's key. During insertion of a latch pin into the rotatable barrel, the maximum torque imparted on a first spur gear by the torsion spring, at a maximum rotation angle of the rotatable barrel, is sufficient to rotate the barrel back to its neutral position after the latch pin has been fully inserted into the barrel, and is less than or equal to a back drive torque limit of a prime mover of the rotary actuator.

A method for operating an access control comprises creating a plurality of wake-up schedules for a wireless transceiver. Each of the plurality of wake-up schedules may be configured to control how frequently the wireless transceiver wakes up to transmit or receive information. Each of the plurality of wake-up schedules for the wireless transceiver may be different from another one or the plurality of wake-up schedules for the wireless transceiver. The method may further comprise automatically switching between the plurality of wake-up schedules for the wireless transceiver such that a duration of time between wake-ups for the wireless transceiver radio is shorter during some predefined times and longer during other predefined times. The duration of time between wake-ups for the wireless transceiver may be configurable by an administrative user via an interface.

A motor vehicle is controlled using a vehicle-external mobile terminal. A communication connection is established using a first transmission/reception device of the motor vehicle and second transmission/reception device of the mobile terminal. A distance and/or relative position of the mobile terminal in relation to the motor vehicle is ascertained by evaluating a radio signal transmitted via the communication connection. Clearance data is generated using a control circuit of the motor vehicle or of the mobile terminal based on the ascertained distance and/or the ascertained relative position. The clearance data indicates that a predetermined control command can be transmitted from the mobile terminal to the motor vehicle and/or is accepted from the mobile terminal by the motor vehicle. The predetermined control command is transmitted using the communication connection when the clearance data are available in the mobile terminal and a predetermined trigger condition for the respective control command is satisfied.

Various implementations of an electric strike are described that includes a casing housing that includes a power source, a lock mechanism, circuitry powered by the power source, the circuitry being configured to authenticate a user, and electro-mechanically actuate the lock mechanism, and a rotor coupled to the lock mechanism, the rotor being powered by the power source and configured to situate the lock mechanism based on a lock state of the electric strike.

A key information sharing system includes a delivery device that delivers key information as first information for a control device equipped in an object and a user terminal that receives the first information delivered from the delivery device. The delivery device adds second information that allows the first information to be transferred between the user terminal and a third-party terminal without the delivery device, to the first information to be delivered to the user terminal. The user terminal transmits the first information to the third-party terminal in response to an input operation by a user, when the user terminal receives the first information to which the second information has been added.

A system according to one embodiment includes a first computing device comprising ultra-wideband communication circuitry, and a second computing device comprising ultra-wideband communication circuitry configured to communicate with the ultra-wideband communication circuitry of the first computing device to determine the angle and distance of the first computing device relative to the second computing device.

A method and system for digital authentication is disclosed, in which an owner device associated with a smart lock receives identity information of a user device requesting access to the smart lock. The owner device registers first contract information of the smart contract, for granting access of the smart lock to the user device, on a decentralized trust network, and sends second contract information about the smart contract to the user device. The second contract information comprises validation information of the smart contract indicating an un-validated information of the second contract information. The user device validates the received second contract information against the first contract information on the decentralized trust network, and authenticates the user device with the smart lock using the validated second contract information.

In one aspect, an in-vehicle device is provided that includes a sensor configured to detect a vehicle characteristic indicative of the vehicle being in proximity to a location associated with a movable barrier operator. The in-vehicle device includes communication circuitry to communicate an open command to the movable barrier operator that causes the movable barrier operator to open a movable barrier connected to the movable barrier operator. A memory is configured to store a vehicle arrival condition indicative of whether the vehicle arrived at the location associated with the movable barrier operator. A processor is configured to determine satisfaction of the vehicle arrival condition and, upon the vehicle arrival condition not being satisfied, cause the communication circuitry to communicate a close command to the movable barrier operator that causes the movable barrier operator to close the movable barrier.

The disclosure provides an electronic lock without an active power source, an electronic lock system, and a method of operating the electronic lock. According to an exemplary embodiment, the electronic lock includes a WPR which receives wireless electrical power to provide power for the electronic lock; a circuit board electrically connected to the WPR and including a wireless transceiver which receives a lock command or an unlock command; and a controller configured to generate a lock control signal or an unlock control signal in response to receiving the lock command or an unlock command; and an actuator electrically connected to the circuit board and receives the lock control signal to lock a mechanical lock component or the unlock control signal to unlock the mechanical lock component.
