Abstract: For each audio pairing broadcast from an electronic device, reporting broadcasted pairing data including: broadcaster device group, broadcast data element, and broadcaster volume setting. For each reception, reporting received pairing data, including: receiver device group, received data element, and received signal score. Matching each received pairing data with zero or one instances of broadcasted pairing data based on a received data element matching the broadcast data element. For each broadcaster reporting a particular group and volume setting, identifying a received signal score value corresponding to a predetermined percentile of a density distribution of such scores matching broadcasters of the particular group. Determining, for each broadcaster of the group, a volume based on: the received signal score corresponding to the predetermined percentile and a reference received signal score.

Abstract: A charging system and method includes a controller that may obtain vehicle system characteristics and/or charger characteristics. The charging system may control a supply of electric power from one or more charging stations to one or more energy storage devices of one or more vehicle systems based at least in part on the vehicle system characteristics and the charger characteristics.

Abstract: Various systems and methods are provided for adjusting operating parameters of an internal combustion engine. In one example, a system may include adjusting an amount of advance of a fuel injection timing of a plurality of fuel injectors of an internal combustion engine relative to top dead center (TDC) responsive to engine output demand, where, as the engine output demand increases, the amount of advance first decreases and then increases. In this way, an amount of vehicle emissions may be decreased while an amount of fuel consumption is decreased.
