Wireless connector system

A method of operating a transmitter module configured for wireless power transfer within a given frequency range, the transmitter module comprising (i) a transmitter antenna and (ii) control circuitry, the method comprising:

• detecting an impedance, via the transmitter antenna, wherein a given impedance range comprises values for the impedance that indicate that any receiver module configured for wireless power transfer within the given frequency range is in a near field of the transmitter module;
• based on the impedance, determining a voltage level that is indicative of the impedance detected, via the transmitter antenna, wherein a given voltage level range comprises values for the voltage level that correlate with the values of the given impedance range;
• based on if the voltage level is within the given voltage level range, sense whether any receiver module configured for wireless power transfer within the given frequency range is in the near field of the transmitter module;
• based on the voltage level, determining whether the voltage level has changed by a threshold amount;
• based on determining whether the voltage level has changed by the threshold amount, determining an activation state for the transmitter antenna whereby:
• if the voltage level is not determined to have changed by the threshold amount, determining that the activation state of the transmitter antenna's wireless transmission of electrical energy need not be changed;
• if the voltage level is determined to have increased by the threshold amount, determining that the activation state of transmitter antenna's wireless transmission of electrical energy is to be changed from deactivated to activated;
• or
• if the voltage level is determined to have decreased by the threshold amount, determining that the activation state of transmitter antenna's wireless transmission of electrical energy is to be changed from activated to deactivated;
• and
• based on the activation state, causing the transmitter antenna to engage in wireless transmission of electrical energy via near-field magnetic coupling.
