A smart key includes: a power supply supplying power; a sensor unit sensing a movement of the smart key; and a controller determining whether a movement sensed by the sensor unit corresponds to a predetermined condition and receiving power from the power supply when the sensed movement of the smart key corresponds to the predetermined condition.

An electronic lockset with a radio frequency harvesting circuit. In one embodiment, the electronic lockset includes a mechanical locking portion movable between a locked position and an unlocked position. One or more energy consumption devices are provided that actuate the mechanical locking portion between the locked position and the unlocked position. A rechargeable battery provides electrical power to the energy consumption devices. A radio frequency (RF) transmitter and RF energy harvesting circuit are used to wirelessly recharge the battery. Typically, the RF transmitter is configured to transmit at a predetermined frequency. The RF energy harvesting circuit is tuned to the predetermined frequency and is electrically coupled with the rechargeable battery to recharge the battery.

A communication device according to one aspect of embodiments includes a controller. In a case where vibration of the communication device is detected, the controller allows execution of a communication process with a communication target device.

In accordance with a first aspect of the present disclosure, a key fob is provided, comprising: a wireless interface for establishing a wireless connection to a controller integrated in a vehicle, wherein the wireless connection enables the key fob to provide access credentials to said controller; a wired interface for connecting the key fob to a console integrated in the vehicle, such that the key fob is usable for carrying out wireless charging of an external mobile device and/or for acting as an anchor device for performing ranging operations with said external mobile device. In accordance with a second aspect of the present disclosure, a corresponding method of configuring a key fob is conceived.

The present disclosure relates generally to apparatus and methods for at least requesting operation of a system configured to control at least a security function for a premises, and wherein a wireless-power receiving device is configured to, upon wirelessly receiving power, receive identification (ID) information from a mobile device and communicate the identification (ID) information to a remote device (e.g. a control panel/control hub or other controller) in order to request operation of the system. The remote device, in response to receiving the request to operate the system, carrying out an authorization process using the identification information from the mobile device.

A wireless key (1) for unlocking a vehicle and/or for enabling a function of the vehicle. The wireless key (1) has a sensor (10) for motion detection, an evaluation unit (20), and a transceiver (30) which is designed to signal its availability as a connection partner and to wirelessly transmit data to a connection partner and/or to receive data from the connection partner. The transceiver (30) has at least one operating mode (A, B) and at least one sleep mode (C, D) where an energy requirement of the transceiver (30) is lower than in the at least one operating mode (A, B). The evaluation unit (20) is designed to switch the transceiver from the operating mode (A, B) to the sleep mode (C, D) if no movement is detected by the sensor (10) within a predetermined interval and to switch the transceiver (30) from the sleep mode (C, D) to the operating mode (A, B) if a movement is detected by the sensor (10).

Embodiments of the present invention are directed to systems and methods for preventing unauthorized access to server racks. In one example, a system includes an electronic key and an electronic lock configured to be attached to the server rack. The electronic lock is configured to communicate with the electronic key for determining whether the electronic key is authorized to unlock or lock the lock. The electronic lock includes a handle configured to be disengaged from the electronic lock when the electronic key is authorized, and the handle is configured to be actuated to unlock the lock for accessing the server rack when the handle is disengaged from the electronic lock. The electronic lock is configured to re-lock only when the handle is engaged with the electronic lock.
