Wireless connections with virtual hysteresis
First Claim
1. A first contactless connector included in a first device for communicating with a second contactless connector included in a second device using extremely high frequency (EHF) signals, the first contactless connector comprising:
- a receiver configured to receive a transmitted EHF electromagnetic signal from the second contactless connector;
an output circuit coupled to the receiver configured to output the transmitted EHF electromagnetic signal when a control signal has a first state and configured to not output the transmitted EHF electromagnetic signal when the control signal has a second state; and
a hysteresis controller coupled to the receiver and the output circuit, the hysteresis controller comprising a rate circuit configured to determine a rate of change of a signal strength of the received EHF electromagnetic signal, the hysteresis controller configured to produce the control signal having the second state if the determined rate of change is greater than a specified threshold.

Abstract
Circuit connectors for establishing EHF communication include a receiver configured to receive a transmitted EHF electromagnetic signal, and an output circuit coupled to the receiver. The output circuit has two states of operation that correspond to enabling a signal output and disabling the signal output. The output circuit is also configured to change its state of operation responsive to a state of a control signal, and a controller is coupled to the receiver and configured to produce the control signal. The control signal has two states that correspond to a first condition when the received signal exceeds a first threshold and a second condition when the received signal is less than a second threshold.
