The communication apparatus has a selector for selecting one or multiple receiver communication devices as a reference communication device that gives a reference timing at which the communication apparatus waits for receiving data, and a timing controller for setting a timing, at which the communication apparatus waits for receiving data, to a timing according to operation of any reference communication device.

Abstract: In an electrophotographic apparatus (e.g., a photocopier or laser printer), an electrophotographic photosensitive member (image-forming part) has a metal substrate roughened on its surface, a metal oxide-containing undercoat layer on the substrate, and an organic photosensitive layer over the undercoat. A coherent light source (e.g., laser) can cause interference fringes that degrade the printed image. Interference fringes are judged (or predicted) as follows: The surface reflectance is measured at intervals over the spectral width of the light source. The measured surface reflectance is corrected, using a mirror-surface conductive substrate as a reference, to obtain a reflectance of the photosensitive member. The reflectance is subjected to a discrete Fourier transformation, which generates a power spectrum, over the spectral width of the light source, from the reflectance as a function of the wavelength.

The video processor alternatively reads the macroblock data stored in the macroblock data storage unit, and compresses the readout macroblock data to an output video signal.

Abstract: A copper/indium/gallium/selenium (CIGS) solar cell including a thermal expansion buffer layer, and a method for fabricating the same are provided. The thermal expansion buffer layer is configured between an alloy thin film layer and a CIGS thin film layer. The thermal expansion buffer layer is deposited by executing a thin film deposition process with a continuous sputtering machine bombarding a cuprous sulphide (Cu2S) or cuprous selenide (Cu2Se) target. Then, a CIGS thin film is further provided on the thermal expansion buffer layer. Finally, a thermal treatment is conducted for melting to integrate the copper ingredients of different thin film layers, thus improving the bondability between the thin film layers and preventing the cracking or the peeling off of the thin film layers caused by the thermal expansion difference.

Abstract: A wireless local area network system includes one or more access points connected to a wired network which is part of the system. To prevent wireless terminals from communicating with a rogue access point that is not connected to the wired network, a legitimate access point detects the rogue access point, determines its beacon signal period, and sets a timer to generate timings at which the rogue access point is expected to transmit the beacon signals. At each of these timings, the legitimate access point creates and transmits interfering data that interfere with the rogue access point's beacon signals.
