  • Patent number: 11917259
    Abstract: A Data Over Cable Interface Specification (DOCSIS) node includes a first DOCSIS port and a second DOCSIS port. The node also includes a plurality of radio frequency (RF) ports. A plurality of client devices can be coupled to the RF ports. A RF switching network is coupled between the first DOCSIS port and the second DOCSIS port, and the plurality of RF ports. One or more control circuits can switch the RF switching network between at least a first state and a second state. The switching of the RF switching network allows the one or more control circuits to identify which client devices are coupled to which RF ports of the node.

  • Publication number: 20230387696
    Abstract: A battery system with a large-format Li-ion battery powers attached equipment by discharging battery cells distributed among a plurality of battery packs. The discharging of the battery cells is controlled in an efficient manner while preserving the expected life of the Li-ion battery cells. Each battery pack internally supports a battery management system and may have identical components, thus supporting an architecture that easily scales to higher power/energy. Battery packs may be added or removed without intervention with a user, where one of battery packs serves as a master battery pack and the remaining battery packs serve as slave battery packs. When the master battery pack is removed, one of the slave battery packs becomes the master battery pack. Charging and discharging of the battery cells is coordinated by the master battery pack with the slave battery packs over a communication channel such as a controller area network (CAN) bus.

  • Patent number: 11753784
    Abstract: A material collection system includes a conduit, a vacuum generator coupled to the conduit, an engine powering the vacuum generator, and a container mounted to a chassis of a vehicle. The vacuum generator generates airflow for drawing material into a material inlet of the conduit. The container receives collected material from the conduit. The material collection container can receive collected material from the conduit. The control system can include a load sensor and a controller in electrical communication with the load sensor. The load sensor can detect a load applied by the collected material received in the material collection container and transmit an output signal indicating the load applied by the collected material. The controller can determine a weight of the collected material received in the material collection container based on the output signal and determine an aggregate weight of the vehicle using the determined weight of the collected material.

  • Publication number: 20230275299
    Abstract: A battery pack protects the internal battery pack components from the heat, e.g., heat generated during a sterilization process of an autoclave. The battery pack prevents the heat of the autoclave from damaging the battery cells and other electronic components within a battery pack housing. The battery pack may include a multi-layer thermal protection portion lining an inside surface of the walls of the battery pack housing with a combination of materials designed to limit the amount of heat to which the internal components of the battery will be exposed for the duration of a traditional autoclave sterilization cycle. Additionally, the battery pack may include a thermal protection casing around connection elements, such as wires and contacts, between a battery pack contact and the battery cells, to limit the heat rise from the heat of the autoclave in or on the connection elements of the battery pack.
