I need to design a wireless battery charging like one of those show in attached pictures. In 1-2 pictures you see planar antenna for wireless power transmission and cylindrical antenna in the receiver section: this is the first possible solution. Second solution (3-4 picture) is to have both cylindrical antennas to have this charging system, anyway the antenna in RX section has to be cyclindrical for mechanical reasons. The RX antenna has maximum lenght of 40mm and inner diameter of 22mm. I need to have a charging minimum current of 1A. Distance between two antennas is about 3mm and there is nylon PA12 between them. In TX section we have not particular constraints in the shape of antenna, you can design rectangular plane antenna too. We have 5Vdc 3A current in TX section. I need to have d...

The goal is to develop a model of a modern HVAC system which is quite complex. The overriding development philosophy is to start simple and add detail. Suggested steps: Get familiar with the two Simscape™-based models of HVAC systems, provided in the background material, and explore results through simulation. Search and learn various topics in HVAC systems. Some starting terms are heat pumps, energy recovery ventilators, forced hot water systems, air handlers, de-humidifiers, and humidifiers. This will give you an overview of some components of a HVAC system. Build a simple model of a room, cold outside environment, and a heating device. Develop a simple controller in Simulink and Stateflow to control the temperature. Add complexity to your model to include a varying environment a...

I need code for zero crossing detection, synced with pwm generator with fixed duty cycle but variable frequency in esp-idf. I need it urgently Its a signal generator like square wave or pwm with fixed 50% duty cycle, but its frequency needs to be varied from 500 to 100Khz (might be done using ledc_timer_1_bit) but when there is zero crossing, its signal needs to be stopped so that igbt should'nt conduct at zero crossing,

Hello can you write a Deep Learning program that improves the performance of the BDF2- Algorithm. I can send you a file where it is explained more precise. The example ODE to train the neural network should contain two differential equations If you can do please place bid. minimize error of BDF2 with machine learning

The project description is summarized in the attached document. I will give the DCO OFDM code showing the random permutations that you can modify to meet the requirements.

The project uses 3 servo motors and ultrasonic sensor and Bluetooth module (HC-05) I need the code to run the project by arduino uno

Generate new code for an ARM series MCU (likely the ATSAME70J19B). Two processors on two separate PCBs will monitor GPIO pins for digital and analog inputs and comparing those values to alarm set points and annunciating alarm status via LED outputs (about 20; green=good, red=alarm). The two micros will communicate between each other via serial ports (converted to RS485 via single chip convertor). A couple other features such as detecting physical key turn-on and time-out-timers will be required. PCBs are being laid out now. Coding should start right away. Will include Ethernet port and Simple GUI for viewing/clearing alarms.

I need a literature review on (Measurements of polymer permeability using NMR). So basically we need to understand the diffusion of polymer nanocompisites using NMR. In this case I have fumed silica and I incorporated it in HDPE (high density poly ethylene) and made a nanocomposite and now I need NMR to get permeability and diffusion characteristics.

1. "idle" state: It is the state when the machine is doing nothing and is idle. In "idle" state, if power button is "on" then the state transition takes place from state "idle" to state "a" and the output is low. If power button is "off ", then the state remains in "idle". 2. "a" state: In state "a", if fill_water is 1(that is if the water gets filled) then the state moves to state "b" otherwise it remains in state "a". 3. "b" state: It is the wash state of the machine. In "b" state, if add_det = 1(that is if the detergent is added) then the state moves to state "c" otherwise remain at state "b". 4. "c" state: It is the rinse state...

I am designing two PCBs (a RF emitter and a RF receiver) and I would like to find someone to give me a hand with it. A summary of specs is presented below: - The emitter (Tx pcb) it is like a keyfob. It should incorporate an encoder (HT12D or similar) along with an RF emitter IC and a PCB printed antenna. This board will be powered with a coin cell (3V). There will be only 2 inputs coming into the encoder. - The receiver (Rx pcb) should incorporate a decoder (HT12E or similar) along with a RF receiver IC and a PCB printed antenna. This board will be powered with a single LiPo Battery (3.7V). There will be 4 outputs. This board should also incorporate a LiPo charging management circuit (TP4056 + DW01 + FS8205) and a DC-DC boost IC (MT3608 or similar) since one of the outputs requires 12...

There is a model which consists of alot of parameters whose values are within a range interval. There is need to use ANN and GA to estimate the values of this parameters which effectively predict the model. All the will be done using MATLAB. If you can successfully handle this , indicate your interest. Thanks

I am looking for a labview programmer who knows how to use these Labview 2018 NI-CAN NI-XNET NI-SWITCH NI-SCOPE i need someone with Electrical Engineering background to help me understand a program someone else written and will need some modifications to it. this will be a long term project, will pay per hour. also if the project needed to be use on my computer, we must need to zoom in and you have to work from my computer. thank you

We are looking automatic wire cutting and stripping machine which can do this job from 0.1 mm wire ( copper wire) upto 6 mm sq and of different lengths. The machine should not use any hydraulic and pneumatic system for Operation. We would be able to give input to the machine through the push button available and also directly through the computer or data stick in case of bulk requirement ( different cable length). If the machine can itself take different cable ( sq mm) and cut it into desired length as per table or input provided in bulk would be great.

I coordinate a design team for the realization of a device that includes an RF section but in the group we have limited knowledge of RF design. In particular I need to make a Class E RF amplifier with the following characteristics: • operating frequency 406.0 MHz • power 5W (37dBm) • TX duty cycle 10ms (transmission time 500 ms every 50 s) • 7.2Vdc power supply • input power 100mW (20dBm) • two-phase modulated input signal • input impedance 50Ω • output impedance 50Ω • efficiency ≥ 70% • operating temperature between -20 and +55 • the output power must go from 10% to 90% of the max power in less than 5ms • must work with VSWR between 1: 1 and 3: 1 • must not be damaged if the load is shorted or open • mus...
