Abstract: A portable device which incorporates a body unit and a display unit incorporating a display screen formed on the front surface and/or the rear surface. The body unit includes sidewalls formed projecting forwards from the left and right side surfaces of the body unit so as to allow the display unit to rest in a stable fashion. Each sidewall of the body unit has a holding member of which one end is secured to one region of the sidewall. A portion of the holding member is positioned inside the display unit. A movement hole is formed in the side surface of the display unit. A portion of the holding member passes through the movement hole so as to allow the display unit to slide on the main body.

Abstract: The invention concerns a wireless communication device making use of a robust wireless communication method (RWCM), and its application on a rear view monitoring system. More specifically, a robust wireless communication device (RWCD) consists of a Data Selection part (11), a Modulation-Demodulation (M-D) part (12) and a TDMA RF Transceiver part (13) that is made up of an ISM Transceiver part (14) and an UHF Transceiver part (15). The Data Selection part (11) sorts the input data into simple or multimedia data, and sends them to the M-D part (12). The simple data are separated into two types: data that do not use multi-media or UHF wave band, and data that do use the UHF band. The M-D method for the former does not include the OOK (On/Off Keying) process which does get used for the latter. In the ISM Transceiver part (14), the non-UHF band simple data and multi-media data are communicated via ISM band or free small-power frequency range.
