Let C be the circle ${x^2} + {(y - 1)^2} = 2,{E_1}$ and ${E_2}$ be two ellipses whose centres lie at the origin and 2 major axes lie on x-axis and y-axis respectively. Let the straight line $x + y = 3$ touch the curves $C,{E_1}$ and ${E_2}$ at $P\left( {{x_1},{y_1}} \right),Q\left( {{x_2},{y_2}} \right)$ and $R\left( {{x_3},{y_3}} \right)$ respectively. Given that P is the mid point of the line segment QR and $PQ = \frac{{2\sqrt 2 }}{3}$, the value of $9\left( {{x_1}{y_1} + {x_2}{y_2} + {x_3}{y_3}} \right)$ is equal to __________
