Systems and methods are provided for authorizing a user to access an access-controlled environment. The system includes a system server platform that communicates with mobile devices (e.g., smartphones) and on-board vehicle computing devices accessed by users. The embodiments enable a series of operations whereby a user accessing a vehicle is prompted to biometrically authenticate using the user's smartphone or on-board vehicle computer. In addition, the system can further authorize the user and electronically facilitate access to the vehicle as well as perform other authorized operations relating to the use of the vehicle. In addition the vehicle access system integrates with various computing devices and computer-based services accessible to the user. The systems and methods also facilitate active monitoring of the vehicle occupants and environmental conditions using optical sensors and the like so as to enhance security, convenience and safety of the occupants during use of the vehicle.

Provided are an alarming method and device. The method includes that: when wireless equipment determines that information, stored in the wireless equipment, of at least one terminal disappears from a connected equipment list, the wireless equipment enters an alert state, wherein the wireless equipment is arranged to access a communication network, terminals access the communication network through the wireless equipment and the connected equipment list records information of all terminals connected to the wireless equipment (S102); and the wireless equipment entering the alert state gives an alarm when a preset condition is met, wherein the preset condition includes that: it is recorded in the connected equipment list that there are still one or more terminals connected with the wireless equipment, and/or, the wireless equipment enters or is in a charging mode (S104).

The present invention describes a system comprised of sensors, microcontrollers, wireless communication modules, and methods for utilizing said sensor system to determine, in real-time, a threat and/or theft of a catalytic converter. An alarm signal is then generated by connecting with the security system of a premises, if available, and relevant parties and law enforcement are notified of the threat and/or theft event.

The method of proximity detection between a first and a second device (DVC1, DVC2), carried out by the first device (DVC1), comprises the steps of collecting a first information on exposure of the first device (DVC1) to electromagnetic waves; receiving a second information on exposure of the second device (DVC2) to electromagnetic waves from the second device (DVC2); determining a matching information between the first information on exposure and the second information on exposure and detecting either proximity or non-proximity between the first and the second device (DVC1, DVC2) based on the matching information.

A method is for activating a vehicle function, wherein a controller for activating the vehicle function checks an access authorization of the mobile device and activates the vehicle function only if the authorization is acceptable. The method includes: a) the controller sending a request to the mobile device demanding transmission of the authorization for a vehicle function, b) the mobile device receiving the request from the controller and sending the authorization to the controller, c) the controller checking the authorization and activates the vehicle function if the authorization is acceptable, d) the mobile device sending the authorization only if the device was previously actuated for the purpose of authorization and thus was authorized to send the authorization, e) and the controller activating the vehicle function only if a signal of a sensor device actuatable by the user has previously been received by the controller.
