A method for collecting data delivered by sensors each containing a measurement element, which sensors are equipped for radio communication and include a device for storing and preparing measurement signals recorded by the respective measurement elements for the transmission of the signals, and an autonomous power source. The method includes the following steps: recording successive raw measurement data corresponding to time-stamped, elementary measurement units of at least one physical or physical-chemical variable or parameter delivered by the measurement element of a particular sensor; in each sensor concerned, storing the raw measurement data in the memory device of the sensor; transmitting the unprocessed raw measurement data in compressed form via a radio link; and collecting, storing and evaluating the raw measurement data transmitted from a multiplicity of sensors in a remote central processing facility.

A voltage sensing device is for sensing an operating voltage of a remote device, based on the measurement of time intervals associated with a chain of repeated communications with the device. The operating voltage of the remote device influences the rise time and fall times of signals sent by the remote device, and these differences in edge slopes of the signals influence the points in time at which signals are detected at the receiving end. Thus, the operating voltage influences a measured transit time of the signals.

Described herein are technologies related to an in-band full-duplex wireless communication operation. More particularly, the technologies utilize a complementary pair of antennas for signal transmission and reception arranged in a new manner to be both compact (relatively to conventional approaches) and provide an extremely high (e.g., 60 dB or more) isolation.
