摘要： A personal communication apparatus is disclosed, which comprises a radio transmitter 64 and a radio receiver 66 for participating in communication, a microphone 60, a loudspeaker 61, a processor 90 as a controller for controlling call switching communication and packet switching communication, a ROM 100 and a RAM 101 for storing control programs and data, a call switching modem 80 for modulating signal in the speech frequency band, and a packet switching modem 82 for modulating signal in a frequency band exceeding the speech frequency band. The outputs of the microphone 60 and call switching modem 80 are bandwidth limited by a transmission signal processing circuit 72. Communication by the packet switching modem is carried out according to a communication program. The apparatus is capable of stand alone call switching communication and also of packet switching communication, as well as functioning as a radio telephone set.

摘要： A display-integrated tablet consuming less power and capable of detecting positions only with top (row) electrodes of a matrix panel without using bottom (column) electrodes of the matrix panel with which position detection is difficult. A display-integrated tablet with a matrix panel having top (row) and bottom (column) electrodes, a top-electrode (row-electrode) drive, a bottom-electrode (column-electrode) driver, a top (row) electrode position detecting section, a bottom (column) electrode position detecting section having a memory storing detection voltage levels and x- and y-coordinate values corresponding to a certain number of dot positions on the panel, and a position detecting conductor, and performing display and position detection by means of time division. It is possible to decrease power consumption without supplying scanning pulses simultaneously to many electrodes (e.g. 20 electrodes) because scanning pulses are supplied only to top (row) electrodes to perform position detection in the position detection mode of the display-integrated tablet by using no bottom (column) electrode.
摘要翻译：一种显示器集成的平板电脑消耗较少的功率，并且能够仅使用矩阵面板的顶部（行）电极来检测位置，而不使用难以进行位置检测的矩阵面板的底部（列）电极。具有具有顶部（行）和底部（列）电极的矩阵面板的显示器集成平板电脑，顶部电极（行电极）驱动器，底部电极（列电极）驱动器，顶部（行）电极位置检测部分，底部（列）电极位置检测部分，具有存储检测电压电平的存储器和对应于面板上一定数量的点位置的x和y坐标值以及位置检测导体，并执行显示和位置通过时间分割检测。因为扫描脉冲仅供给顶部（行）电极，所以可以同时向许多电极（例如20个电极）提供扫描脉冲，从而降低功耗，从而通过使用no来在显示器集成平板电脑的位置检测模式下执行位置检测底（柱）电极。
