    摘要: Systems and methods are provided for conveyor operation and maintenance that employ one or both of a “smart shoe” technology where one or more conveyor shoes incorporate features, such as an RFID tag, and a “missing pin detection” technology where one or more pin components of conveyor shoes incorporate features, such as an RFID tag, allowing selective wireless tracking and identification capability. A conveyor system comprises a shoe management system allowing interactions directly with one or more RFID readers, which can detect, store and/or monitor information associated with “smart shoe” and/or “missing pin detection” RFID tags, where interface between this application and the reader can be implemented via a socket interface. An open platform communications (OPC) wrapper can be created around the interface so that a Human Machine Interface (HMI) could interact directly with shoe management system.

    摘要: In aspects of UWB accessory for a wireless device, an attachable ultra-wideband (UWB) accessory includes a UWB radio to communicate with UWB radios in an environment. The attachable UWB accessory has one or more wireless interfaces to wirelessly communicate with radio devices of a wireless device to which the UWB accessory is attached. The attachable UWB accessory can also include a micro-controller that receives UWB ranging data from the UWB radios, and may determine a location of the wireless device in the environment based on the UWB ranging data. The attachable UWB accessory may utilize Bluetooth low energy (BLE) for UWB out-of-band communications. A wireless device can be implemented with the attachable UWB accessory, and the wireless device has a BLE interface to interface with the UWB accessory.

    摘要: Embodiments of this application disclose a communication apparatus. The communication apparatus may include a first transceiver, a second transceiver, and a power amplifier. The first transceiver and the second transceiver may be separately connected to the power amplifier. In this way, when it is determined that a network load is relatively low, any transceiver in the communication apparatus may be turned off. Because the turned-off transceiver no longer continues to generate power consumption, power consumption of the entire communication apparatus is reduced, to achieve an energy saving effect. In addition, when an electronic component in the communication apparatus is turned off, the power amplifier may not be turned off, and the power amplifier may still receive a corresponding radio frequency signal from a transceiver that is not turned off, to perform power amplification and send a corresponding radio frequency signal.

    摘要: An electronic device may include wireless circuitry with a processor that generates baseband signals, an upconversion circuit that upconverts the baseband signals to radio-frequency signals, a power amplifier, an antenna, and a transmit filter with a frequency dependent filter response coupled between the output of the power amplifier and the antenna. To help mitigate the frequency dependent filter response, the wireless circuitry may further include predistortion circuitry having an amplifier load response estimator that implements a baseband model of the filter response, an amplifier non-linearity estimator that models the non-linear behavior of the amplifier, and a control signal generator for adjusting the power amplifier based on the output of the amplifier load response estimator and the amplifier non-linearity estimator.

    摘要: A system includes a battery pack having a first battery module, a second battery module, and a busbar that couples the first and second battery modules; a battery management controller having a first wireless transceiver; and a battery monitor coupled to the first battery module and to the busbar. The battery monitor includes monitoring circuitry configured to receive a first indication of a parameter of the first battery module; a second wireless transceiver configured to provide the first indication to the battery management controller via a wireless connection to the first wireless transceiver; and a busbar voltage circuit configured to receive a second indication of a voltage across the busbar, and, responsive to the second indication being greater than a voltage threshold, provide a first signal to the second wireless transceiver to cause the second wireless transceiver to be in a higher-power state.
