The battery monitoring techniques described herein use a self-characterizing wireless monitor coupled to a battery to monitor different properties of the battery. The wireless monitor may measure, among other things, an alternating current frequency response (ACFR) of the battery. To accomplish this, the wireless monitor may generate and inject a stimulus signal into the battery, and the monitor may then synchronously measure the corresponding impedance response of the battery.

Self-characterizing smart cells for battery lifecycle management

Described herein is a device for autonomously monitoring a battery is provided. The device is integrated with the battery (e.g., by being electrically coupled to the battery). The device obtains measurement data by injecting electrical signals into the battery and measuring an electrical response of the battery. The device participates in an authentication protocol with a computing device to verify a unique identity of the device to the computing device. After performing the authentication protocol verifying the unique identity of the device, the device transmits battery data to the computer. Further, techniques for verifying the identity of the battery using measurement data obtained by the device are described herein. The techniques generate a battery signature using the measurement data that is then used to verify the identity of the battery. For example, the battery signature may be used to determine whether the battery is counterfeit or defective.

Autonomous battery monitoring system

A wireless communication system includes a network manager configured to wirelessly communicate with a plurality of wireless nodes of a wireless network. The network manager and at least one wireless node include a transceiver connected to transmit and receive wireless communication via an antenna. The network manager and/or the wireless node include a cognitive engine configured to receive information regarding an environment of the wireless network as input and, in response, generate configuration data as output. Subsequent communication on the wireless network is updated using the configuration data.

Smart scheduling of TSCH networks to avoid self-interference

A wireless communication system includes at least one transmitter and at least one receiver. The transmitter is configured to establish wireless link parameters and transmit a data communication using the wireless link parameters. The receiver is configured to receive the data communication, automatically identify one or more of the wireless link parameters using the data, and extract a payload using the identified wireless link parameters. Prior to receiving the data communication, the receiver requires limited information concerning the wireless link parameters established by the transmitter. The wireless link parameters can include selectable aspects such as one or more of a transmission channel, a transmission data rate, a modulation format, a transmission power, a packet format, and a channel coding scheme.

Adaptive detection of wireless link parameters

A system and method for increasing capacity and throughput in a wireless network includes a plurality of wireless nodes configured to communicate wirelessly with one another on respective frequency channels according to a schedule. The schedule includes timeslots. For respective timeslots, first and second transmitting wireless nodes generate transmissions for a receiving wireless node. The receiving wireless node includes a receiver circuit configured to receive the transmissions from the first and the second transmitting wireless nodes simultaneously and on separate frequency channels, and a transmitter circuit configured to generate acknowledgment packets for the first and the second transmitting wireless nodes upon receipt of the transmissions by the receiving wireless node.

Multi-channel communication using timeslots

A system and method for providing multiple modes of communication in wireless networks includes a network manager and a plurality of network nodes. The plurality of network nodes form a wireless network with the network manager and are configured to communicate data to the network manager using respective communication links having a first bandwidth. The plurality of network nodes are further configured to transition to a two-hop mode of communication upon one or more failures in communication to the network manager. While in the two-hop mode of communication, a respective network node of the plurality of nodes is configured to transmit node data to at least one other network node over a communication link having a second bandwidth different than the first bandwidth. The other network nodes are configured to listen for communication from the respective network node and re-transmit to the network manager the node data received from the respective network node.
