Abstract: Two connected electronic devices may use a controller and two power converters to share battery charge. The two electronic devices may share charge after one electronic device's battery is completely discharged. In the alternative, the two electronic devices may compare the relative age of the two batteries and if the age difference exceeds a predetermined threshold, the younger battery may share charge until it is insufficiently charged to power both electronic devices.

Abstract: Aspects of the disclosure provide a circuit that includes a switch control circuit and a timing control circuit. The switch control circuit is configured to enable/disable a pulse width modulation (PWM) switch control to a regulator to transfer power to a load. The timing control circuit is configured to enable an analog to digital converter (ADC) to convert an analog signal to a digital stream when the PWM switch control is disabled in order to reduce noise in the digital stream due to switching activities in the regulator.

Abstract: A system, method, and article of manufacture for online crowd-sourcing and for communicating with a requester and with several of workers, the system includes a central controller that communicates with each requester via an interface, to receive the task(s) to be performed and to provide a response for that task(s), and with each worker via an interface, to deliver task assignments and to receive responses, the central controller further including a task assignment system that is structured and arranged to insert tasks to be performed into a priority queue multiple times and to push a next task in the priority queue to a selected worker based on information about the selected worker; and a data storage device for storing information about workers that includes a worker identification, a worker skill level, a worker accuracy rating, a list of historical tasks performed by the worker, and a list of historical tasks that the worker has not performed.
