Disclosed is a method of performing communication by a smart module in a home network system. The method includes: obtaining device level information of a device; identifying whether the device level information of the device indicates a device level which can provide only a mandatory function; when the device level information of the device indicates the performance which can provide only the mandatory function, transmitting a status request message making a request for status information of the device to the device; receiving a status response message including information indicating whether a status of the device has changed; and when the information indicates that the status of the device has changed, transmitting an event generation message to a host system.

A flexible substrate, which has a photosensitive agent applied thereon, is continuously supplied from a supply unit to a guide unit where light is irradiated from a light source on a section of the substrate. A mask is positioned between the substrate and the light source so that the light from the light source selectively subjects the section of the substrate to exposure. Hence, it is possible to form a pattern having a continuous slanted structure for a large-area display panel.

Fabrication and mounting of an array of M.times.N mirrors on an array of M.times.N electrodisplacive actuators is carried out by one of the two inventive methods, comprising the steps of: patterning a substrate into an array of M.times.N protrusions; forming subsequently a separation layer, a first, a second and a third metallic layers on a top of the array of M.times.N protrusions; bonding the array of M.times.N actuators on the protrusions; disengaging the array of M.times.N protrusions from an array of M.times.N mirror bodies by removing the separation layer; and forming a fourth metallic layer on the first metallic layer so as to provide the reflector to thereby provide the array of M.times.N actuated mirrors. The other method comprises the steps of: clamping physically a thin glass on a top surface of a substrate; plating a top surface of the thin glass with a bonding layer; bonding the array of M.times.N actuators on a top surface of the bonding layer and removing a portions of the bonding layer which is not connected with a top surface of the array of M.times.N actuators; forming a metallic layer on the thin glass; patterning the metallic layer into the array of M.times.N mirrors; cutting a portion of the thin glass which is not contacted with the array of M.times.N mirror to thereby provide the array of M.times.N actuated mirror.
