Abstract: A computer implemented method includes receiving, from an inter-vehicular charge recipient having a recipient vehicle, a request to arrange an inter-vehicular charge and a battery charge level for the battery of the recipient vehicle. A battery charge level for a battery of the donor vehicle is received from an inter-vehicular charge donor vehicle, and an anticipated route of the donor vehicle and an anticipated route of the recipient vehicle is obtained. The battery charge level of the battery of the recipient vehicle is compared to the battery charge level of the battery of the donor vehicle to determine a suitability for inter-vehicular charging, and the anticipated route of the donor vehicle is compared to the anticipated route of the recipient vehicle to determine a location to initiate charging. The method then generates and sends a proposal for an inter-vehicular charge transaction to the donor vehicle.

Abstract: An electronic device may be provided with more than one industry-standard type of AC power connector. The electronic device may be powered in any of a variety of locations by selectively exposing one of the power connectors selected according to an AC power outlet available at that location. A location-specific power cord may be used to connect the exposed power connector to the AC power outlet. The location-specific power cord may have, for example, a line socket at one end of a type that matches the exposed power connector, and a power plug at the other end of a type that matches the AC power outlet at the location. Predefined power settings appropriate for use with the AC power outlet and the exposed power connector may be automatically invoked.

Abstract: An arrangement for controlling a system generated noise level such that the same is adapted to an actual ambient noise level of the system environment. Internal noise generators will thus not run at a needlessly lowered rate than actually needed. For instance, by permitting a fan to run at a generally higher speed, the system will not needlessly undergo significant internal temperature increases. By the same token, CPU performance, to the extent that it represents a noise generator, will not be needlessly throttled.
