In accordance with a first aspect of the present disclosure, a system is provided for facilitating localizing an external object, the system comprising: a plurality of ultra-wideband (UWB) communication nodes; a controller operatively coupled to said plurality of UWB communication nodes, wherein the controller is configured to: cause at least one of the UWB communication nodes to transmit one or more UWB messages to other UWB communication nodes of said plurality of UWB communication nodes; receive a channel impulse response (CIR) estimate and/or one or more parameters relating to said CIR output by the UWB communication nodes in response to receiving said UWB messages; analyze said CIR estimate and/or said parameters relating to the CIR; select a localization process in dependence on a result of analyzing said CIR estimate and/or said parameters relating to the CIR. In accordance with further aspects of the present disclosure, a corresponding method is conceived, and a computer program for carrying out said method is provided.

A distance determination method has: detecting a first received signal strength indicator (RSSI) of a first electronic device by a second electronic device; detecting a second RSSI of the second electronic device by the first electronic device; obtaining the first RSSI from the second electronic device by the first electronic device; and calculating a motion direction and a distance of the second electronic device relative to the first electronic device according to the first RSSI and the second RSSI by the first electronic device.

Systems and methods for keybox status determination are disclosed. In some embodiments, a system for determining a status of a keycontainer of a lockbox comprises one or more sensors configured to generate output signals related to the keycontainer. The system further 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, a status of the keycontainer, the status indicating whether the keycontainer is released from the keybox; and send a status notification based on the determined status of the keycontainer.

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.

A vehicle authorization system with a transmitter/receiver capable of activating vehicle functions operably connected to the vehicle, a wireless transmitter/receiver for an authorized vehicle operator that receives communications from the vehicle transmitter/receiver, a sensor in the vehicle security transmitter/receiver that detects at least one vehicle access parameter via an electronic signal, wherein the vehicle transmitter/receiver communicates with the wireless transmitter/receiver responsive to the sensor detecting a second signal associated with the access parameter to affirm a verification signal from the wireless transmitter/receiver that upon verification permits vehicle access by the operator or upon improper or no response activates a vehicle function to prevent access or vehicle operation. The invention consists of a vehicle security device that can both monitor and control vehicle systems, and a user's smart device. The invention is combined with the existing vehicle keys and fobs to provide a two-step authentication.

There is provided a method and a system for authorizing a user device to send a request to a vehicle in order to prevent a physical layer relay attack. The system comprises a vehicle comprising an acoustic transducer and an RF transceiver and a user device comprising an acoustic transducer and an RF transceiver. The method relates to a signaling scheme using a combination of acoustic and RF signals for preventing a successful physical layer relay attack.

A method of activating a vehicle function is provided. The method includes detecting a force exerted onto a bed step of a vehicle using a pressure sensor. A controller detects whether the amount of force exerted onto the bed step is greater than a force threshold. When the force exertion force exceeds the force threshold, one of a plurality of pressure patterns is detected. One of a plurality of vehicle functions is then activated based on the detected pressure pattern.

In an information processing system including a terminal device carried by a user and a server device communicably connected to the terminal device by a secure communication method, the terminal device acquires a sensing result in a real space where the terminal device is located and sends the same to the server device, and the server device holds base information for specifying at least one position in the real space as an information processing base, and sends an information processing instruction to the terminal device in a case where a predetermined condition defined using a distance or a direction between a position specified by the sensing result received from the terminal device and a position specified by the base information is satisfied.

Disclosed is a door lock device. The door lock device comprises: a communication unit for receiving location information of an electronic device and a key from the electronic device; a location information reception unit for receiving location information of the door lock device; a door lock unit having a locked state or a released state; and a control unit electrically connected with the communication unit, the location information reception unit, and the door lock unit, wherein the control unit determines a distance between the electronic device and the door lock device on the basis of the location information of the electronic device and the location information of the door lock device, and determines whether to release the door lock unit on the basis of information of the distance.

A vehicular security system includes a remote device with a first biometric sensor. An electronic control unit (ECU) of a vehicle processes data captured by the first biometric sensor to determine whether an identity of the user of the remote device matches an authorized user of the vehicle. The ECU, responsive to determining that the user is authorized to use the vehicle, unlocks a door of the vehicle to allow the identified authorized user to access the vehicle. The system includes a second biometric sensor disposed in the vehicle and, with the identified authorized user in the vehicle, the ECU, via processing data captured by the second biometric sensor, determines whether the identity of the identified authorized user of vehicle matches an authorized operator of the vehicle. The ECU, responsive to determining that the user is an authorized operator of the vehicle, allows operation of the vehicle.
