Multiple order connectors for contactless communication devices and methods for using the same are disclosed herein. In some embodiments, a first device for use in establishing a contactless communications link with a second device is provided. The first device can include a first order connection, which can be constructed to interface with a counterpart first order connection of the second device, and a second order connection. The second order connection can include a substrate, at least one contactless communications unit (CCU) mounted on the substrate and that is operative to establish the contactless communications link with a respective counterpart CCU of the second device, and an actuator operative to move the substrate such that the at least one CCU is optimally aligned with its respective counterpart CCU to establish the contactless communications link.

A signal transmission system including: a first connector apparatus, and a second connector apparatus that is coupled with the first connector apparatus. The first connector apparatus and the second connector apparatus are coupled together to form an electromagnetic field coupling unit, and a transmission object signal is converted into a radio signal, which is then transmitted through the electromagnetic field coupling unit, between the first connector apparatus and the second connector apparatus.

The present invention relates to a system for providing distributed communication between communication terminals and a method for same. The method for providing distributed communication between communication terminals in a communication system includes the steps of: a first communication terminal receiving at least one first signal from at least one target communication device; the first communication terminal collecting at least one second signal that at least one second communication terminal receives from the at least one target communication device and at least one third signal that the at least one second communication terminal obtains by processing the at least one second signal in a preset processing scheme; and the first communication terminal combining the at least one first signal and the at least one second signal, or the at least one first signal and the at least one third signal.

A configurable RF transmit/receive (TX/RX) multiplexer, which includes a group of RF TX bandpass filters, a group of RF TX switching elements, and a group of RF RX bandpass filters; is disclosed. Each of the group of RF RX bandpass filters is coupled to a first common connection node. Each of the group of RF TX switching elements is coupled between a corresponding one of the group of RF TX bandpass filters and the first common connection node, which is coupled to a first RF antenna.
