A programmable locking assembly for an insulated food grade container, such as a food delivery container, that can be unlocked by the recipient of the container by pressing a number code on the keypad of the lock, causing a locking finger to slide out from a zipper pull on the lid of the insulated food grade container to allow the recipient to unzip the lid to gain access to the contents of the container, thereby preventing the food delivery person to access the contents of the container while in route to making the delivery. In an alternate embodiment, an audio tone can open the lock without the user needing to press numbers on the keypad. The number code and/or the audio tone are texted to the recipient's cellular phone from the sender of the container.

It is provided a method for requesting remote unlocking of an electronic lock controlling access to a physical space. The method is performed in a user device and comprises steps of: sending a control message to an access controller, the control message comprising user authentication information, the control message causing the access controller to trigger the electronic lock to emit an alert signal; and sending an unlock message to the access controller comprising the user authentication information, in order to unlock the electronic lock.

A programmable locking assembly for an insulated enclosure such as a food delivery box that can be unlocked by the recipient of the box, by pressing a number code on the keypad of the lock, causing a locking finger to slide out from a zipper pull on the lid of the insulated enclosure to allow the recipient unzip the lid to have access to the contents of the enclosure, thereby preventing the food delivery person to access the contents of the enclosure while in route to making the delivery. The number code is texted to the recipient from the sender of the enclosure. In an alternate embodiment, an audio tone can open the lock without the user needing to press numbers on the keypad.

In some examples, a control system for a vehicle can detect a set of ultrasonic signals generated by a mobile computing device of a user. Additionally, the control system can determine a pin code from the set of ultrasonic signals. Moreover, the control system can perform one or more vehicle operations to initiate fulfillment of a transport request that is associated with the determined pin code, upon the user being determined to be within a given proximity distance of the vehicle.

The present disclosure improves security in a technology for unlocking an electronic lock using a door phone slave unit. A business phone main unit (2) includes: a PB signal reception unit (22) that receives a PB signal input through a door phone slave unit (5); an authentication information decoding unit (23) that decodes authentication information from a PB signal; and an electronic lock control unit (25) that controls an electronic lock (4) based on the decoded authentication information.

A frictionless access control system and method providing ultrasonic user location are disclosed. The access control system authorizes users within proximity of an access point such as a door, based upon user information (e.g. credentials) sent in RF wireless messages from user devices carried by the users. When the users are authorized, the system instructs the user devices to transmit coded acoustic signals. An positioning unit at the access point includes an ultrasonic microphone array, which is located above the access point and detects the acoustic signals. The positioning unit determines an angle of arrival (AoA) of the acoustic signals at microphones of the array, and determines positions of the users relative to the access point from the AoA. In one implementation, pre-authorized users are granted access when the determined positions of the users are within an inner zone of the access point.

An entry and starting system in an object has a control and transmission unit configured to use a radio link to interchange at least one radio signal and an ultrasonic link to interchange at least one ultrasonic signal with a portable electronic device. The control and transmission unit sets up a radio link to the portable electronic device and uses the electronic device via the radio link to stipulate at least one relevant parameter for a subsequent ultrasonic link. The control and transmission unit is additionally configured so as, following the stipulation of the parameters, to set up an ultrasonic link according to the previously determined parameters. The entry and starting system checks an authorization of the portable electronic device, the portable electronic device being detected as authorized if the at least one relevant parameter of a subsequent ultrasonic link is concordant with the at least one stipulated parameter.

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.
