The front-end electronics (FEE) noise characterization to electromagnetic interference and the compatibility of the different subsystems are important topics to consider for the LHC calorimeter upgrades. A new power distribution scheme based on switching power converters is under study and will define a noticeable noise source very close to the detector’s FEE. Knowledge and experience with both...

Congenital insensitivity to pain with anhidrosis is a rare disease of the nervous system which causes one to lose his/her feeling of pain. The disease is subtype four of hereditary sensory and autonomic neuropathy (HSAN IV) that results from NTRK1 gene defect. Direct sequencing was performed to screen NTRK1 for mutations. The result revealed a homozygous deletion of adenine on intron 14 that ma...

High-frequency electromagnetic fields in the 120 kHz band emitted from card readers for access control systems caused abnormally high doses on electronic pocket dosimeters (EPDs). All EPDs recovered their normal performance by resetting after the exposure ceased. The electric and magnetic immunity levels of the EPDs were estimated by using the distances needed to prevent electromagnetic interfe...

A novel transparent Co0.2Fe2.8O4@SiO2-polyetheretherketone hybrid material is prepared for electromagnetic interference shielding via in situ sol-gel process. 20% amino-functionalized polyetheretherketone (AFPEEK), containing trifluoromethyl units with excellent solubility is designed and synthesized to improve the stability and mechanical properties of Co0.2Fe2.8O4@SiO2 nanoparticles. The hydr...

This work aims to compare the implementation of two metamaterials for reducing electromagnetic interference (EMI) in printed circuit boards (PCBs). Specifically, complementary split-ring resonators (CSRRs) and electromagnetic bandgaps (EBGs) were etched on the ground plane of a microstrip transmission line. Both techniques were compared as EMI filters, taking into account frequency response, si...

To investigate electromagnetic interference (EMI) of electromagnetic fields (EMF) from electronic article surveillance (EAS) systems with electronic implants numerical anatomical models of pacemaker patients were generated accounting for different implantation sites (left pectoral, right pectoral and abdominal) and body size. Induced interference voltages were calculated with a software package...

We present the design of an asynchronous microcontroller core featuring binary compatibility with the MCS 251 family. The work is involved in a specific application project targeting portable electromagnetic measurement systems with very low power consumption. Delay insensitivity was chosen to allow a fast design of complex but safe asynchronous circuits, by means of automatic synthesis and ind...
