Methods and systems are provided for supporting efficient and secure “Machine-to-Machine” (M2M) communications using a module, a server, and an application. A module can communicate with the server by accessing the Internet, and the module can include a sensor and/or an actuator. The module, server, and application can utilize public key infrastructure (PKI) such as public keys and private keys. The module can internally derive pairs of private/public keys using cryptographic algorithms and a first set of parameters. A server can authenticate the submission of derived public keys and an associated module identity. The server can use a first server private key and a second set of parameters to (i) send module data to the application and (ii) receive module instructions from the application. The server can use a second server private key and the first set of parameters to communicate with the module.

An electronic device includes: a location measurement circuitry; a rechargeable battery; a memory configured to store instructions; and at least one processor. The at least one processor may be configured to execute the instructions to: monitor a usage pattern of the battery while the electronic device operates in a first power management state; acquire, based on determining that the usage pattern of the battery is different from a reference pattern derived from a model, information on a location in which the battery is estimated to be charged and information on a time at which the battery is estimated to be charged using the model; and switch, partially based on the information on the location and the information on the time, the first power management state to a second power management state based on a second maximum driving frequency lower than the first maximum driving frequency.

Systems, methods, and computer-readable media for managing near field communications during a low power management mode of an electronic device are provided that may make credentials of a near field communication (“NFC”) component appropriately secure and appropriately accessible while also limiting the power consumption of the NFC component and of other components of the electronic device.

There is provided a control device that is configured to control an aircraft which has a battery, and a base station unit for providing a wireless communication service to a user terminal in a communication area formed by using power of the battery to radiate a beam on a ground, and which is configured to use the power of the battery to fly, the control device including: a battery capacity acquisition unit configured to acquire a battery capacity of the battery; and a communication control unit configured to control an amount of communication resources which is allocated to the user terminal by the base station unit based on the battery capacity.

A method of initiating handover of a wireless device includes determining one or more of a low battery condition, a low power headroom, and a high buffer status of a wireless device. The wireless device can be attached to a first access node deploying multiple radio access technologies over a first coverage area. The method further includes identifying a second access node deploying a single radio access technology over a second coverage area encompassing a location of the wireless device, and initiating handover of the wireless device from the first access node to the second access node based at least in part on the one or more of the low battery condition, low power headroom, and high buffer status of the wireless device. Systems and devices relate to initiating handover of a wireless device.

A device includes a wireless transceiver coupled to a microcontroller. The microcontroller is configured to receive a first command from the wireless transceiver indicating an uplink allocation for the device, and in response to the first command, cause the wireless transceiver to turn ON at the beginning of the device's uplink allocation, send data to the wireless transceiver for wireless transmission, and cause the wireless transceiver to enter a low power mode after the data has been transmitted by the wireless transceiver. The microcontroller is also configured to receive a second command from the wireless transceiver to transition to a low power mode, and in response to the second command, send data to the wireless transceiver for wireless transmission during the uplink allocation for the device, and receive data from the wireless transceiver during uplink allocations for at least one other device.

A server device is provided, the server device comprising a processing circuitry, a memory circuitry, an interface circuitry configured to connect to a communication network. The server device is configured to obtain machine data indicative of one or more features of a machine. The machine is configured to be powered by a battery device. The server device is configured to obtain usage data indicative of a usage of the machine. The server device is configured to obtain, for one or more battery devices, battery data indicative of one or more battery parameters of a battery device. The server device is configured to determine, for the one or more battery devices, a predicted impact on the one or more battery parameters based on the battery data, the usage data, and the machine data.

A communication device for connection with a power source and a host device is provided. The communication device comprises a device controller and a converter circuit. The device controller is adapted for data communication with the host device and the converter circuit is configured to provide a virtual device ground at least to the device controller, so as to compensate a ground potential difference between the host device and the communication device.

Embodiments disclosed herein relate to reducing a power consumption of an electronic device while maintaining some functionality of the electronic device while the electronic device is in a low power mode. The device may be in the low power mode due to a battery level being below a threshold. If the battery level is below the threshold, the electronic device may enter the low power mode. However, before entering the low power mode, some functionality of an application processor may be transferred to a communication controller. Once the functionality is transferred, the application processor may be disabled to reduce power consumption while maintaining functionality of the application processor. The electronic device may also utilize various communication protocols to communicate with a peripheral device. Even though the electronic device may be in the low power mode, the communication controller may be used to cause the peripheral device to perform various actions.

A method for inferring a status asset information from data of a first type gathered by a first asset tracking device is provided. The method includes determining that a first asset tracking device coupled to a first asset and a second asset tracking device coupled to a second asset are travelling together, that the first asset tracking device has a first operating mode, and that the second asset tracking device has a second operating mode, which is different from the first operating mode of the first asset tracking device. In response, the second asset tracking device enters into a low-power mode in which it either does not gather data of the first type or does so at a reduced rate. Status information related to the second asset may be inferred from data of the first type gathered by the first asset tracking device.
