A delivery assistance device assists in an operation of a delivery service in which an inside of a vehicle, a building, or a facility used by a user is designated as a delivery destination of luggage. The delivery assistance device includes a storage unit, a registration unit configured to register, in the storage unit, a plurality of candidates as delivery destinations of the luggage and priorities for the candidates, and a delivery destination decision unit configured to decide an alternative delivery destination from among the candidates based on the priorities when a deliverer is not able to deliver a delivery destination with the highest priority among the delivery destinations, the delivery destination with the highest priority being designated by the user.

Disclosed are a battery replacement device (1″) and a control method therefor. The battery replacement device (1″) is used for mounting a battery on an electric vehicle, and sending a security message to a battery lock (2″) to unlock the battery, so that the battery is electrically connected to the electric vehicle.

An electronic key system determines that legitimate communication has been performed on the basis of conditions including that a measured distance from a ranging request unit to a ranging response unit measured on the basis of a ranging request signal and a ranging response signal is within a threshold range that is set on the basis of the distance from a communication area of a transmission antenna where an electronic key is determined to be located by a key location determination unit to one of either the ranging request unit or the ranging response unit that is provided in an on-board device.

The present disclosure includes secure communication between a vehicle and a remote device. An embodiment includes a processing resource, memory, and a vehicular communication component configured to, in response to receiving a request from a remote communication component to switch a state of a lock, calculate a challenge count for the request, generate a vehicular private key and a vehicular public key, perform a number of verification iterations, each respective verification iteration including providing the public key to the remote communication component, receiving, from the remote communication component, code for switching the lock state, verifying the remote communication component's identity, and incrementing a counter in response to verifying the remote communication component's identity, and decrypt the code using the private key and switch the lock state in response to the counter being incremented to a value equal to or greater than the challenge count.

A near-field communication (NFC) entry device provides remote keyless entry (RKE) into an enclosure having an RKE control unit, a door, and a door actuator. The NFC entry device includes a housing and a printed circuit board assembly (PCBA). The housing mounts to the enclosure. The PCBA is enclosed within a cavity of the housing, and includes first and second surfaces, an RF antenna and an inductor coil connected to the first surface, and an NFC communication chipset connected to the second surface. The NFC entry device passively harvests energy from a battery powered mobile device via the inductor coil and stores the energy in the capacitor. The passively harvested energy is used to communicate a control signal to the RKE control unit, via the RF antenna, which activates the door actuator. A standby battery may be used when the capacitor is insufficiency charged.

A method of transmitting signals from a first node having multiple transceivers to a second node is disclosed. The method comprises receiving a message from the second node at the first node, wherein the message is received by each of a plurality of transceivers of the first node; and transmitting by each of the plurality of transceivers a respective data frame to the second node in response to the message; wherein each transceiver initiates the transmission of its respective data frame a predetermined time period after receipt of the message by the transceiver; and wherein the transmissions of the data frames from the plurality of transceivers overlap. The data frames may form part of a two-way ranging exchange.

In a method of registering a smart key for construction machinery, a first password is generated in a smart key module mounted in a construction machine. A user setting graphic interface through which a user can input a password, in the smart key module or a user terminal, is provided to the user. The password inputted by the user is compared with the first password in the smart key module to authenticate. An authentication code of a near smart key that is recognized by the smart key module is registered as a new registration authentication code when the inputted password is authenticated.

Systems and methods for cloud-based keyless entry are generally described. In some examples, a first number is received from a vehicle. A first computing device of the vehicle may be configured to control an electronic door lock. A first unlock code may be generated using the first number. In some examples, a notification is sent to a remote entry device associated with the vehicle. A response to the notification may be received from the remote entry device. In some examples, the first number may be retrieved from a messaging service based at least in part on the receiving the response to the notification. A second unlock code may be generated using the first number. A determination may be made that the first unlock code matches the second unlock code. An instruction may be sent to the first computing device, the instruction effective to cause unlock of the electronic door lock.

A system for secure sensor operation is provided. A sensor circuit includes a smart controller configured to provide trusted data. An operational circuit includes an operational controller configured to, responsive to receipt of a request from the sensor circuit, perform an identity verification using a cryptographic challenge to authenticate the sensor circuit before utilizing the trusted data.

A method includes receiving a request to assume control of a vehicle generated by a candidate operator via a first communication pathway. The method obtains a key from an onboard controller of the vehicle and communicates the key to the candidate operator via a second communication pathway that is different from the first communication pathway. The method determines the candidate operator to be a confirmed operator based at least in part on obtaining the key from the candidate operator via the first communication pathway.
