By using wireless sensors inside homes and on personal items, it becomes possible to monitor a person's behavior and environment while protecting their privacy. This enables the compilation of statistics and allows the activation of prompts and alarms for remote assistance. Radio frequency identifications (RFIDs) are energetically autonomous being battery-less and can be used for this approach. A typical RFID system is composed of a digital device called tag that is embedded in an antenna. An IC chip with a unique identification code (ID) is used with a reader, radio scanner device. This enables continuous and reliable monitoring of critical parameters such as the temperature, humidity, and gaseous components. Sensing volatile molecules in a noninvasive manner can serve in breath analysis to recognize marker gases for distinguishing between healthy and sick people. Air monitoring can also be used to avoid inhalation of antiseptics in surgical rooms to monitor hazardous gases in hospital environments and prevent epidemics. A passive RFID tag becomes capable to detect changes of the chemical/physical parameters of the environment when it is integrated with specific chemical compounds or the microchip networks [4].
On the Producer/Consumer problem: buffers and semaphores
Published in Uri Abraham, Models for Concurrency, 2020
Consider two processes called Consumer and Producer that continuously repeat the following operations: The producer produces an item and hands it over to the consumer who takes and consumes it. For example, the producer may be a radio scanner and the consumer an analyzer of the data obtained. The scanner directs its antennas to outer space and scans a range of frequencies; it listens for a very short period to each frequency in its range (one frequency after the other) and hands out the raw data obtained to the analyzer (the consumer) which checks if this is just noise or some interesting information. In the latter case it may alert a more sensitive receiver to tune in to the interesting frequency for a longer period. This producer-consumer team must act in good and swift coordination because any lost item may be important.
Performance comparison of microstrip antenna and dielectric resonator antenna (DRA) at RFID application
Published in Arun Kumar Sinha, John Pradeep Darsy, Computer-Aided Developments: Electronics and Communication, 2019
RFID is an automatic identification technology, which uses RF signal to identify the objects and collect the relevant data in a non-contact manner. A basic RFID system consists of three components: a data carrier (also called a Tag or a Transponder), a radio-scanner unit (also called a Reader) which is called antenna. The early RFID technology is applicable back to radar equipment which was invented in 1930’s and aircraft Identification Friend or Foe system which was invented by the British Air Force and widely used in allied forces during World War II (1939) [1–3]. Compared with the traditional automatic identification system (e.g. barcodes) this proposed technology has many advantages. The identification target does not need to be visible and it will be under secured conditions.

Digital images of all plants were made with a digital camera (Sony®, model DSC-H9, São Paulo, SP, Brazil). To qualitatively assess herbicide translocation, plants were exposed on X-ray films (Perkin Elmer®, Super Resolution, PPN 7001487, Shelton, WA, USA) for 48 h. Images were developed with a radio scanner (Perkin Elmer® Storage Phosphor System, Cyclone Plus model, Shelton, WA, USA).
