Abstract
A device includes an integrated power receive circuit, a battery charger, a battery, a processing module, one or more input/output modules, and one or more circuit modules. The integrated power receive circuit is operable to generate a DC voltage from a received magnetic field in accordance with a control signal. The battery charger is operable to convert the DC voltage into a battery charge voltage. The battery is coupled to the battery charger in a first mode and is coupled to supply power in a second mode. The processing module is operable to: generate the control signal based on desired electromagnetic properties of at least one of the received magnetic field and the integrated power receive circuit; process outbound data to produce processed outbound data; and process inbound data to produce processed inbound data.
