#include <vector>
#include <functional>

// For simplicity, we'll just define a type alias for our sensor readings
using SensorData = std::vector<int>;

// Sensor Reader class to simulate real-time sensor data acquisition
class SensorReader {
    SensorReader(std::function<SensorData()> readFunction, int readInterval)
    : readFunction_(readFunction), readInterval_(readInterval) {
        readingThread_ = std::thread(&SensorReader::readData, this);
    ~SensorReader() {
        isActive_ = false;
    SensorData getLastReading() {
        std::lock_guard<std::mutex> lock(dataMutex_);
        return lastReading_;

    void readData() {
        while (isActive_) {
            // Emulate sensor reading delay
                std::lock_guard<std::mutex> lock(dataMutex_);
                lastReading_ = readFunction_();

    std::function<SensorData()> readFunction_;
    int readInterval_; // milliseconds
    SensorData lastReading_;
    std::mutex dataMutex_;
    std::thread readingThread_;
    bool isActive_ = true;

// Processing class for applying algorithms to sensor data
class DataProcessor {
    void processData(SensorData data) {
        // Placeholder for complex processing algorithm
        for (int& value : data) {
            // Simulate processing on the data
            value *= 2; 
        processedData_ = data;
    SensorData getProcessedData() {
        return processedData_;
    SensorData processedData_;

// Main System class for real-time biomedical application
class BiomedicalSystem {
    : sensorReader_([this] { return simulateSensorReading(); }, 500) { // 500 ms interval

    void run() {
        while (systemActive_) {
            SensorData rawData = sensorReader_.getLastReading();
            SensorData processed = dataProcessor_.getProcessedData();
            // Placeholder: would interact with other system components here
            std::cout << 'Processed Data: ';
            for (int value : processed) {
                std::cout << value << ' ';
            std::cout << std::endl;
            std::this_thread::sleep_for(std::chrono::seconds(1)); // Main loop delay
    SensorData simulateSensorReading() {
        // Simulates reading data from a biomedical sensor
        SensorData data = {1, 2, 3, 4, 5}; // Example sensor data
        return data;
    SensorReader sensorReader_;
    DataProcessor dataProcessor_;
    bool systemActive_ = true;

int main() {
    BiomedicalSystem system;
    return 0;

Code Output:

The expected output will continuously print ‘Processed Data: ‘ followed by the processed sensor values which are double the original simulated sensor readings. You will see an output similar to:

Processed Data: 2 4 6 8 10 
Processed Data: 2 4 6 8 10 
Processed Data: 2 4 6 8 10 

This output would continuously loop until the program is manually stopped. It represents the processed data from the simulated sensor being outputted every second.

Code Explanation:

The C++ program is designed to represent a real-time system application in the field of biomedical engineering. The program is modular, consisting of three major components: SensorReader, DataProcessor, and the main BiomedicalSystem class.

SensorReader: This class encapsulates the reading of sensor data. It uses a separate thread to simulate the acquisition of real-time sensor data, allowing the main system to perform other operations without blocking. It uses a mutex to protect access to the last reading, ensuring thread safety.

DataProcessor: A simple class that represents the data processing algorithm to be applied to the sensor data. In a real-world scenario, this could be a sophisticated signal processing algorithm specific to biomedical applications, but here it just doubles the values for demonstration purposes.

BiomedicalSystem: The central class that integrates SensorReader and DataProcessor to simulate a real-time biomedical application. It periodically retrieves the last sensor reading, processes it, and outputs the result. The main system loop represents the ongoing nature of biomedical monitoring systems where sensor data is constantly being acquired, processed, and used.

The main() function: This function demonstrates how all components come together to form the system. It creates a BiomedicalSystem instance and initiates the system run by calling its run() method. This would emulate a real-world application where the system is always on, monitoring sensor data and processing it in real-time.
