The paper presents a new class of state observers for linear systems with sampled and delayed output measurements. These observers are derived using the theory of a particular class of hybrid systems called piecewise-continuous systems, and can be easily implemented. The performances of the piecewise-continuous observers are compared with the performances of state observers designed using the Lyapunov-Krasovskii techniques. A piecewise-continuous observer is designed and implemented to an experimental visual servoing platform.

P-type Mg doped CuAlO2 films with high crystallinity are prepared by pulsed laser deposition followed by annealing, and exhibit enhanced conductivity and tunable optical band gaps.
