A removable module includes circuitry, a near field communication (NFC) coupler to provide a data signal to the circuitry, and a second NFC coupler to supply operating voltage to the circuitry.

Backplane with near field coupling to modules

A system is provided in which a set of modules each have a substrate on which is mounted a radio frequency (RF) transmitter and/or an RF receiver coupled to a near field communication (NFC) coupler located on the substrate. Each module has a housing that surrounds and encloses the substrate. The housing has a port region on a surface of the housing. Each module has a field confiner located between the NFC coupler and the port region on the housing configured to guide electromagnetic energy emanated from the NFC coupler through the port region to a port region of an adjacent module.

Guided near field communication for short range data communication

A system is provided which includes a signal generator for generating a periodic excitation signal and an analog to digital converter, wherein the system is configured to apply the periodic excitation signal to a network including a known first impedance and a second impedance and to take a first set of M digital samples of a first signal relating to the first impedance and a second set of M digital samples of a second signal relating to the second impedance with a sampling frequency that is an integer multiple of the frequency of the periodic signal. The system is further configured to determine the impedance value of the second impedance by calculating a relative phase difference between the first signal and the second signal using the first set of digital samples and the second set of digital samples.
