  • Patent number: 11405869
    Abstract: Disclosed examples offer ways to manage dialogues between radio frequency-enabled devices and conserve energy of the devices. A system includes a plurality of radio frequency-enabled nodes networked to communicate with a radio frequency-enabled device. The radio frequency-enabled device includes a radio frequency transceiver and a processing device. The processing device is configured to, in response to expiration of a time period or an occurrence of an event, transition the radio frequency-enable device from a standby mode to a transmit mode. In the transmit mode, a start dialogue message is broadcast. After a pause of a predetermined length following the transmission of the start dialogue message, the radio frequency-enabled device transitions to a receive mode to receive a data packet transmitted from one or more of the radio frequency-enabled nodes. Upon completion of receiving the data packet, the radio frequency-enabled device transitions from the receive mode to the standby mode.

  • Patent number: 11399271
    Abstract: A system for appending an emergency call (e.g., E911) with a location is described herein. The system appends the emergency call to a public safety answering point (PSAP) with a location, including an amended or up-to-the-minute location, from which the emergency call occurred. A user equipment, which places the emergency call, includes cache memory. The location is stored in or retained in the cache memory. The UE, upon recognizing the “911” string for the emergency call, retrieves the location from the UE and appends the call with the location. A location module is used to determine the location of UE. A movement module determines UE movement, including direction, speed, acceleration, and the like. The location of the UE can be amended based on the movement of the UE.

  • Patent number: 11166178
    Abstract: Methods and devices for maintaining a device-operated function. A first device initially operates as an active master with responsibility to execute the device-operated function by automatically performing one or more operation tasks according to certain operational parameters and gaining knowledge when performing the operation tasks. Meanwhile, a second device is acting as a passive standby device. When the first device cannot or should not operate as the active master anymore, e.g. due to low battery, the responsibility is transferred to the second device by transferring the operational parameters and the knowledge from the first device to the second device. Then, the second device operates as the active master with responsibility to execute the device-operated function according to the operational parameters and using the knowledge if required.

  • Patent number: 11160117
    Abstract: Methods, systems, and devices for wireless communications are described that provide for transmission of idle mode requests using random access techniques, and for identifying a response window for a response to idle mode requests. A user equipment (UE) may transmit an idle mode request using random access channel resources, and the response window may be longer than a response window associated with a random access procedure for initial system access. The response window may be determined based at least in part on a base station that is to provide the response to the idle mode request.

  • Patent number: 11109313
    Abstract: A cellular modem is configured for low power applications. In some instances, the cellular modem includes a transceiver, a processor to control the transceiver, a memory device in communication with the processor, and a general-purpose input/output (GPIO) pin, controlled by the processor. In an example, the cellular modem receives an appointed time for an upcoming communication and determines a time to activate a power supply. The determination may be based at least in part on the appointed time for the communication, so that the power supply is ready to supply power at a level consistent with use of the transceiver at the appointed time of the communication. At the determined time, a signal from the GPIO pin is used to activate the power supply, resulting in an increase in power supplied to the cellular modem in a just-in-time manner.
