To address the problems of low selling efficiency, poor sanitation conditions, labor-intensive requirement, and quick rice cooling speed in manual rice selling in cafeterias, especially in colleges and secondary schools, this paper presented an Advanced RISC Machines (ARM) microprocessor-based rice-selling machine for cafeterias. The machines consisted of a funnel-shaped rice bin, a thermal insulation box, and a conveying and scattering mechanism. Moreover, this machine exerts fuzzy control over stepper motor rpm, and the motor drives the conveyor belt with a scraper to scatter rice, deliver it, and keep it warm. Apart from an external 4*4 keyboard, a point of sale (POS) machine, an ARM process and a pressure sensor, the machine is also equipped with card swiping and weighting mechanisms to achieve functions of card swiping payment and precise measurement, respectively. In addition, detection of the right amount of rice and the alarm function are achieved using an ultrasonic sensor and a beeper, respectively. The presence of the rice container on the rice outlet is detected by an optoelectronic switch. Results show that this rice-selling machine achieves precise measurement, quick card swiping, fast rice selling, stable operation, and good rice heat preservation. Therefore, the mechanical design enables the machine to achieve its goals.

Wearable devices have been popularly used with people from different age groups. As a consequence, the concerns of their electromagnetic field (EMF) exposure to the human body and their electromagnetic interference (EMI) to the implanted medical devices have attracted many studies. The aim of this study was to evaluate the human exposure to the EMF of an active radiofrequency identification (RFID) armlet as well as its EMI to the cardiac pacemaker (CP). Different human models from various age groups were applied to assess the result variability. The scalar potential finite element method was utilized in the simulation. Local EMF exposure and the exposure to the central nerve system tissues were evaluated using different metrics. EMI to the CP was assessed in terms of the conducted voltage to the CP. The results from all the models revealed that the studied RFID armlet would not produce the EMF exposure exceeding the safety limits. The calculated interference voltage was highly dependent on the distance between the RFID armlet and the CP (i.e. the physical dimension of the individual model). The results proposed to evaluate the appropriateness of the current EMI measurement protocol for this kind of devices used by the infants.

The paper aims to benchmark the performances of dual-frequency inlays, operating in the UHF and HF bands, when deployed in the apparel logistics and end user retail processes. The developed testing protocol makes it possible to evaluate the performances of RFID devices in simulated supply chain and end user-oriented processes. It has been designed considering the need for identification of the supply chain and the end users, who can take advantage of the adoption of NFC technology. We applied the testing procedure to RFID inlays equipped with an innovative integrated circuit (IC) and two antennas, capable of managing both EPC communication in the UHF band and NFC communication in the HF band with smart devices. The performances of the inlays were compared to those of standard tags commonly used in the EPC and NFC fields. We measured and compared the read rate, accuracy and read time when testing EPC capabilities and the read/write throughput, time and distance when measuring NFC functionalities. By simulating a real-world environment, the test results provide a direct insight into the performances that can be expected from different dual-frequency RFID inlays. This information is useful for IT and logistics managers, who can better understand how these innovative tags perform and which would be the best choice for new RFID applications.
