Abstract: A system with an earpiece that comprises a rechargeable earpiece power source and a case that is configured to interface with the earpiece in an earpiece power source charging configuration and comprises a case power source that is configured to recharge the earpiece power source. A detection circuit, located in part in the earpiece and in part in the case, includes at least one earpiece electrical contact that is configured to electrically couple to at least one case electrical contact when the earpiece is interfaced with the case in the earpiece power source charging configuration. The detection circuit is configured to detect, using the earpiece and case electrical contacts, whether the earpiece is interfaced with the case in the earpiece power source charging configuration, even if one of the earpiece power source and the case power source does not have power.

Abstract: A cooktop power control system for a cooktop that has a plurality of burners, where the cooktop power control system controls the power delivered from two or more separate active burners to separate cookware items each of which is associated with an active burner. There is a maximum limit of total power that is available for delivery from all of the burners together. There is a heating control user interface associated with each of the burners, each heating control user interface constructed and arranged to be set by a user to a particular heating control user interface setting. A desired cookware temperature is derived from the setting of each heating control user interface. The measured temperatures of the cookware items are available to the cooktop power control system.
