Abstract: Presented are feedback control systems for monitoring battery system hardware, methods for making/operating such systems, and vehicles with wireless battery management systems (WBMS) governed through distributed feedback control. A method of operating a WBMS includes a wireless-enabled manager device selecting a batch of cell module assemblies (CMA) within the WBMS to communicate with to thereby retrieve data for their respective battery modules. A manager access control list (ACL) is created with respective media access control (MAC) addresses and ID data for the selected CMAs. A wireless connection is established between the manager device and a respective cell monitoring unit (CMU) for each selected CMA based on the corresponding MAC addresses and ID data in the manager ACL. The manager device downloads, from the CMU of each selected CMA, device data for each battery modules associated with the selected CMA. The manager device then switches the operating mode for each CMU.

Abstract: An automatic checkout system for a supermarket, or other retail merchandise store or the like. The system includes a checkout counter and a bagging cart movably mounted to the rear of the checkout counter for supporting bags orientated to receive items from the checkout counter. In one mode of operation, the cart is positioned to allow the operator to both check out and load merchandise items into the bags on the cart. In another mode of operation, the cart is rotated away from the checkout counter and a counter shelf is positioned between the cart and the checkout counter to allow a bagger to continue to receive and load items from the checkout counter into the same bags. The construction of the checkout counter and the bagging cart allows transition from one mode of operation to the other to occur without interrupting the checkout operation.
