摘要： Methods, apparatus, systems, and articles of manufacture are disclosed to improve one-hop extension in wireless battery management systems. An example apparatus is to cause transmission of an instruction to a first battery monitoring node (BMN) of a vehicle, the first BMN in communication with the apparatus the instruction to cause the first BMN to operate as a repeater for a second BMN of the vehicle, the second BMN noncommunicative with the apparatus. The example apparatus is to process an acknowledgement from the first BMN indicating that the first BMN has configured to operate as the repeater. Additionally, the example apparatus is to cause transmission of a communication to at least the first BMN indicating a time at which at least the first BMN is to perform a first action associated with a first battery and the second BMN is to perform a second action associated with a second battery.

摘要： Dynamic sharing of RAM in a software-defined communication system includes storing program code in a flash memory, categorizing parts of the code into groups of transmit categories according to when a part of the code needs to be copied into a section of a RAM and then executed during a first state of a TX state machine and according to how another part of the code can be later fit into the same section and then executed during a second state. Similarly, parts of the code are categorized into groups of receive categories according to when a part of the code needs to be copied into a section of RAM and then executed during a first state of a RX state machine and according to how another part of the code can be later fit into that section and then executed during a second state of the RX state machine, to reduce the amount of RAM without sacrificing speed performance.

摘要： A system is provided for calibrating a device. The system includes a reference component, a sampling component, a calibration component, a comparing component and a proportional integral component. The reference component provides a reference power signal based on a voltage instruction and a current instruction. The sampling component samples a voltage signal to obtain a sampled voltage value and samples a current signal to obtain a sampled current value. The calibration component generates a calibrated power signal based on the sampled voltage value and the sampled current. The comparing component generates an error signal based on the reference power signal and the calibrated power signal. The proportional integral component and the calibration component are a feedback system that is operable to calibrate the gain of the sampled voltage and the sample current based on the error signal.

摘要： At least some aspects of the present disclosure provide for a method of data transmission, performed by a wireless device. In some examples, the method includes receiving a localization tone having a first value. The method further includes inserting the localization tone into a data packet at an application layer of a communication protocol stack, the localization tone preceding data of a payload of the data packet and having a last bit immediately preceding a first bit of the data of the payload. The method further includes generating a modified localization tone estimating an effect of processing on the localization tone, wherein the modified localization tone is generated and configured to have the first value after undergoing processing. The method further includes replacing the localization tone in the data packet with the modified localization tone. The method further includes transmitting the data packet.
