Aiming sustainability and great demand of electric energy, there is a need for new technologies development, creating equipments to reduce costs generated by electric energy consumption, this article presents a prototype of control and energy monitoring applied dimmable LED lamp illumination circuit in a room, zenital architecture and sheds topology. To keep appropriated luminosity level, this system act monitoring natural light available on the environment and adjusting luminosity of the lamps, the control basis used in this project is a PID controller with retroaction because it is an industrial control algorithm very disseminated on automation sector which although being a robust system, it is very easy understanding and provide satisfactory results on automated processes. The control and monitoring take place from reading of luminosity sensors, of tension and current installed on prototype besides an LCD display that shows information from data obtained by sensors, this system has more flexibility to the user. A PID controller was designed to analyze and domain process, driving the system to get highest efficiency levels.

—This paper summarises a novel microstrip patch antenna design over flexible Teflon substrate having dielectric constant εr= 2.1. The proposed antenna exploits a King shaped slot (0.05mm thick) on the radiating patch along with microstrip feed line and reduced ground plane on the other side of the substrate. The radiating element of the flexible flanged antenna design has a King-shaped slot and a finite ground plane to accomplish an excellent impedance matching for maximum power transfer. The proposed antenna has an operating bandwidth of 550.7MHz (3.1244GHz-3.675GHz) with resonant frequency at 3.42GHz and has also an operating bandwidth of 369.1MHz (8.3507GHz-8.7198GHz) with resonant frequency at 8.3609GHz. This flexible flanged microstrip patch antenna design covers various applications including Radio astronomy/ Radiolocation (military&civil)/ UWB/PMSE/FSS Earth stations applications (3.3GHz-3.6GHz), Radio-determination/ Space-research/Fixed applications (8.4GHz-8.5GHz), activesensors (satellite)/ Radiolocation (civil&military)/ Aeronautical-navigation applications (8.5-8.55GHz). The proposed antenna operates for acceptable voltage standing wave ratio (VSWR) less than two. The characteristics of the proposed antenna fabricated on a flexible Teflon with different bending angles have been successfully measured. The antenna has been designed in CST Microwave Studio 2014. The proposed antenna has been fabricated and tested using E5071C Network analyser and anechoic chamber. It has been observed that the simulated results legitimately match with the experimental results.

—In this work, the size of the antenna has been optimized by introducing an air-filled cavity into the lower substrate of the antenna with two layers. Analysis and modeling were performed using the HFSS (High Frequency Structure Simulator) simulator based on the finite element method. The simulation results obtained for the reflection coefficient, bandwidth, and gain were compared with those published. This comparison showed a good satisfaction Keywords— Multilayer patch antenna, K band, air-filled cavity, S11, gain, bandwidth, HFSS.

Brain-to-machine-interface (BMI) that facilitates the healing of Spinal Injuries. The Product is designed to facilitate the healing of scar tissues along the vertebrae column. This works perfectly for persons having a handicap that hinders motor skills. The BMI performs this operation by generating a series of electromagnetic propagations throughout the vertebrae column. It will also be designed to target specific areas of extreme abrasion(s) that affect proper blood flow to facilitate the easy flow of blood (as before injury), so that patient(s) once again would experience the use of their limbs. The device will be engineered as such to cause the brain, where necessary, to (possibly) adjust its own internal frequencies (in Hz) and pitch (in W s/cm 2) to aid in this process. It will be disclosed that through the adjustment of frequencies (in Hz) and energy density (in W s/cm2) scar tissues can be corrected.

—There are various types of microstrip antenna that can be used for number of applications in wireless communication. In this paper, the design of Sierpienski fractal Slotted Hexagonal Microstrip Patch Antenna with FR4 glass epoxy substrate having dielectric constant, E r of 4.4, and thickness 1.6mm has been presented. It is instigated using stripline feeding. These antennas are compact, conformal to both the surfaces-planar& non-planar, simple, inexpensive, rugged, compatible with MMIC designs. Microstrip antenna is made up of a very thin metallic strip (patch) i.e, placed over a small fraction of a wavelength above a ground plane. The simulated results indicate that the antenna is suitable for RADAR (all types), GPS carriers, WLANs, Wimax, Satellite communication, navigation. The design is simulated using IE3D software and result is obtained in terms of smith chart, VSWR, return loss.

— This paper presents the structural and dielectric properties of polyurethane palm oil based filled empty fruit bunch. Polyurethane filled with empty fruit bunch (PU-EFB) composite was prepared through hot press process. The crystal structure of PU-EFB has been studied using X-ray diffraction technique. The effect of EFB filler content on the microwave dielectric properties of the PU-EFB composites was studied in the X-Band frequency region using Vector Network Analyzerat room temperature. A Kraszewski model showed good correspondence with measured dielectric constant of PU-EFB composite, especially at the higher loading level. Keywords—dielectric properties, PU-EFB composite, polyurethane palm oil based.

Microwave imaging is the method that used to detect breast cancer. Previous research is done by inverse problem and forward problem solution, but the inverse problem is difficult to solve because there are many unknown constants. Thus in this paper, microwave imaging is solved by different way, i.e. using forward problem solution only with the aim to easier the imaging process without ignoring the resolution. So the malignant breast cancer is easier to detect and this technique can be used as an easy, safe, and cheap of early detection of the breast cancer. This process is done by illuminating normal and malignant breast tissue model using microwave at frequencies 5GHz, 10GHz, and 15GHz. Then the scattered field data are calculated by Method of Moment. The scattered field data is presented in 2D figure. The results show that normal and malignant breast tissue produce different scattered field patterns. The normal breast tissue tends to produce more curve pattern around object. This difference in patterns can be used as a reference to distinguish b etween normal and malignant breast tissue.
