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;
a low-pass filter connected to the receiver and configured to generate an averaged signal proportional to a strength of the transmitted EHF signal;
an enable circuit configured to receive the transmitted EHF signal from an output of the low pass filter, the enable circuit configured to output the transmitted EHF signal when a control signal has a first state and configured to not output the transmitted EHF signal when the control signal has a second state; and
a hysteresis logic circuit connected to the low-pass filter and the enable circuit, the hysteresis logic circuit configured to;
produce the control signal having the second state until the determined signal strength of the averaged signal exceeds a first threshold for a first time interval, whereupon the controller produces the control signal having the first state to enable the enable circuit to output the transmitted EHF signal from the receiver; and
thereafterproduce the control signal with the second state to disable the enable circuit from outputting the transmitted EHF signal from the receiver when the determined signal strength of the averaged signal fails to meet a second threshold for a second time interval.

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.

12. 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 receive the transmitted EHF signal from an output of the receiver, the output circuit configured to; output the transmitted EHF signal when a control signal has a first state and configured to not output the transmitted EHF signal when the control signal has a second state; and a controller coupled to the receiver and configured to; determine a signal strength of the transmitted EHF signal; increment a first timer responsive to determining that the determined signal strength is above a first threshold; produce the control signal having the second state until the first timer reaches a first terminal count, whereupon the controller produces the control signal having the first state to enable the output circuit to output the transmitted EHF signal from the receiver; increment a second timer responsive to determining that the determined signal strength is below a second threshold; and produce the control signal with the second state to disable the output circuit from outputting the transmitted EHF signal from the receiver when the second timer reaches a second terminal count. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
