Explanation of Solution

Method "matrixAdd()" to return the added values of two dimensional array:

//Definition of class Test

public class Test

{

//Definition of main class

public static void main(String[] args)

{

//Create an two dimensional array

int a[][] = { { 10, 20 },

{ 15, 25}};

int b[][] = { { 25, 35 },

{ 25, 15}};

//Call the method matrixAdd()

int res[][]=matrixAdd(a, b);

//For loop to print the array

for(int i=0; i<a.length; i++) {

for(int j=0;j<b.length;j++)

{

System.out.print(" "+res[i][j]);

}

}

}

//Definition of method matrixAdd

public static int[][] matrixAdd(int[][] a, int[][] b)

{

//Declare the required variables

int rows = a.length;

int cols = 0;

//Check whether the rows is greater than 0

if (rows > 0)

{

//Get the length of array

cols = a[0]...

You are tasked with developing a portable system that can be worn to collect health and fitness data. The challenge is to integrate all functions into the smaller form of an ear clip. The device should include heart rate, movement and temperature sensor and wireless communication with a mobile app. Draw a diagram- hardware architecture of the system- including the selection of suitable sensors, communication modules, and an energy-efficient microcontroller. (visualize the components and their connections)
