Abstract

“Smart” connectors with embedded processors, measurement circuits and control circuits are disclosed for establishing a “contactless” radio frequency (RF) electromagnetic (EM) Extremely High Frequency (EHF) communications link between two electronic devices having host systems. The connectors are capable of monitoring, controlling, and directing (managing) link operation to dynamically adapt to conditions, as well as monitoring and altering (or modifying) data passing through the connector, and selecting a protocol suitable for a communications session. The connectors are capable of identifying the type of content being transferred, providing authentication and security services, and enabling application support for the host systems based on the type of connection or the type of content. The connectors may operate independently of the host systems, and may perform at least one of sensing proximity of a nearby object; detecting a shape of a nearby object; and detecting vibrations.

notifying a host system connected to the first contactless connector that the communications link failure is imminent.

4. The method of claim 1, further comprising:

using a maximum power level to establish the contactless communications link;

after the communications link is established, decreasing the power level of the contactless signal to a lower power level sufficient for maintaining the contactless communications link.

5. The method of claim 1, wherein the adjusting the power level comprises dynamically adjusting the power level to maximize a data transfer rate.
