17. In a wireless device having an antenna system with at least one inductive element and two or more capacitive elements, a switching component configured to change a circuit configuration of the capacitive elements, a controller configured to transmit a signal using the antenna system and to receive a response from a first device, to determine a communications protocol associated with the first device and to change a configuration of the antenna system in response to the detected communications protocol by actuating the switching component, wherein the controller is configured to detect whether the first device is within proximity to the controller and to transmit the signal in response to the detection, wherein the controller is configured to transmit a first signal and to wait a predetermined period of time for a response, and then to transmit a second signal if no response is received, wherein the controller is configured to transmit a first signal in accordance with a first protocol and to wait a predetermined period of time for a response, and then to transmit a second signal in accordance with a second protocol if no response is received, wherein the controller is configured to transmit additional signals in accordance with additional protocols until a response is received, wherein the controller is configured to maximize a power transfer or efficiency by tuning a transmitting entity and a receiving entity to each resonate at a frequency, wherein the switching component comprises one or more high-bandwidth, low-loss switches, and further comprising a device configured to measure one of a voltage, a current or a power in the device, and wherein the controller is configured to actuate the switches as a function of the measured voltage, current or power in the device, wherein the controller is configured to transmit a signal that can generate a response in accordance with multiple different protocols, a method comprising:
-
transmitting a signal to an antenna system comprising at least one inductive element and two or more capacitive elements; receiving a response from a first device; determining a communications protocol associated with the first device; changing a configuration of the antenna system in response to the detected communications protocol by actuating a switching component configured to change a circuit configuration of the capacitive elements; detecting whether the first device is within proximity to the controller; transmitting the signal in response to the detection; transmitting a first signal; waiting a predetermined period of time for a response; transmitting a second signal if no response is received; transmitting a first signal in accordance with a first protocol; waiting a predetermined period of time for a response; transmitting a second signal in accordance with a second protocol if no response is received; transmitting additional signals in accordance with additional protocols until a response is received; maximizing a power transfer or efficiency by tuning a transmitting entity and a receiving entity to each resonate at a frequency; wherein the switching component comprises one or more high-bandwidth, low-loss switches, and further comprising; measuring one of a voltage, a current or a power in the device; actuating the switches as a function of the measured voltage, current or power in the device; and transmitting a signal that can generate a response in accordance with multiple different protocols.
