Abstract: A system includes a first plurality of secondary devices, each secondary device of the first plurality of secondary devices including a first wireless transmitter and a battery monitor integrated circuit (IC). The battery monitor IC is configured to obtain battery data from at least one battery cell, and the first wireless transmitter is configured to wirelessly transmit the battery data. A first primary device has a second wireless transmitter wirelessly coupled to the first wireless transmitters of the first plurality of secondary devices via a first wireless network. A second primary device has a second wireless transmitter. The second primary device is configured to detect a fault with the first primary device and, in response detection of the fault, to establish a second wireless network with the first plurality of secondary devices.

Abstract: In an example, a method includes adding a first request from a first requestor to a queue for a shared resource, where the first request has a first priority. The method includes providing the first request to the shared resource from the queue. The method includes processing the first request at the shared resource. The method includes adding a second request from a second requestor to the queue for the shared resource, where the second request has a second priority that is higher than the first priority. The method includes preempting the processing of the first request and notifying the first requestor of the preemption, where notifying the first requestor of the preemption includes providing the first requestor with a duration of availability for the shared resource. The method includes providing the second request to the shared resource from the queue and processing the second request at the shared resource.

Abstract: 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.
