  • Publication number: 20250058969
    Abstract: A refuse vehicle has a Commercial and a Residential Mode whereby when in Commercial Mode, stops or fins, utilized in Residential Mode to assist in securing a residential container laterally at the front of the vehicle, are adjustable to prevent contact or interference with the cab protector or other portions of the vehicle when in Commercial Mode. The fins may be located and/or rotated, such as at least 30 degrees (from position to position) or above a horizontal or otherwise intermediate the residential and commercial configurations. The fins may preferably be located above a bottom of the crossbar when moving through the dumping cycle so as not to contact the cab protector in Commercial Mode. Preferably, the fins may also be housed on the residential refuse container rather than along the crossbar.

  • Publication number: 20250030246
    Abstract: Systems and method for reducing load from a power grid by offloading residences that have energy storage appliances (e.g., rechargeable vehicle or wall batteries), may be utilized by an electric power provider to help increase available electrical power on a power grid so as to reduce pricing for electrical power. The power provider may have customers (i) who opt-into authorizing the power provider to offload the customers' residences when the appliances are available to supply power to electric power networks of respective residences (e.g., when an EV is plugged into a power station), and (ii) who do not opt-in. If sufficient amount of power cannot be offloaded from the opt-in customers, messages with offers to the non-opt-in customers may be send to identify additional energy resources. The power provider may send commands to cause the appliances to offload the residences. Moreover, a price optimization engine may be used for energy market pricing.
