ultrasonic sensor and mlx90614 temperature sensor.

i have a mission to let the ultrasonic sensor and the mlx90614 sensor work together it means that when the mlx90614 temperature sensor detects a high temprature in a short distance from an object (distance info is given by the ultrasonic sensor) a buzzer works.
i have the code for the ultrasonic sensor:
//Ultasonic Sensor

//Pins connected to the ultrasonic sensor
#define trigPin 2
#define echoPin 3
//LED pins
#define ledGreen 9
#define ledRed 8
//Pin connected to the piezo buzzer
#define alarm 11

int range = 5;//range in inches

void setup() {
// initialize serial communication:
//initialize the sensor pins
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
//initialize LED pins
pinMode(ledGreen, OUTPUT);
pinMode(ledRed, OUTPUT);
//set LEDs
digitalWrite(ledGreen, HIGH);
digitalWrite(ledRed, LOW);

void loop()
// establish variables for duration of the ping,
// and the distance result in inches and centimeters:
long duration, inches, cm;

// The PING))) is triggered by a HIGH pulse of 2 or more microseconds.
// Give a short LOW pulse beforehand to ensure a clean HIGH pulse:
digitalWrite(trigPin, LOW);
digitalWrite(trigPin, HIGH);
digitalWrite(trigPin, LOW);

// Take reading on echo pin
duration = pulseIn(echoPin, HIGH);

// convert the time into a distance
inches = microsecondsToInches(duration);
cm = microsecondsToCentimeters(duration);

Serial.print("in, ");

if(inches < 5) {
digitalWrite(ledGreen, LOW);
digitalWrite(ledRed, HIGH);
tone(alarm, 2000);
} else {
digitalWrite(ledGreen, HIGH);
digitalWrite(ledRed, LOW);


long microsecondsToInches(long microseconds)
// According to Parallax’s datasheet for the PING))), there are
// 73.746 microseconds per inch (i.e. sound travels at 1130 feet per
// second). This gives the distance travelled by the ping, outbound
// and return, so we divide by 2 to get the distance of the obstacle.
// See: http://www.parallax.com/dl/docs/prod/acc/28015-PING-v1.3.pdf
return microseconds / 74 / 2;

long microsecondsToCentimeters(long microseconds)
// The speed of sound is 340 m/s or 29 microseconds per centimeter.
// The ping travels out and back, so to find the distance of the
// object we take half of the distance travelled.
return microseconds / 29 / 2;

but i dont have the mlx90614 code …
so can anyone help me by giving me the mlx90614 code and to tell me how can i combine these two sensors to work together like i mentioned above…
please help !!!
