    • A drowsiness alarm system for a vehicle detects the driver's increasing state of drowsiness on a basis of abnormal steering change repetitions for a fixed period of time in a monotonous driving state defined, for example, as the gear shift lever being placed at an overdrive or top position. The alarm system produces an alarm to the driver to prevent the driver from increasing the state of drowsiness. The drowsiness alarm system according to the present invention comprises: (a) a steering signal generator which generates a signal corresponding to the change of an angle through which the steering wheel is rotated; (b) a monotonous driving-state detector which detects and signals that the vehicle is traveling in a monotonous driving state; (c) a discriminator which compares the change of steering signal level from said steering signal generator for a fixed period of time with a reference value; and (d) an alarm pulse generator which outputs an alarm pulse into an alarm circuit producing an alarm in response to the input alarm pulse when the output signal from the discriminator indicating the change of steering signal for the fixed period of time exceed the reference voltage.
    • 用于车辆的睡意报警系统在单调驾驶状态下,基于异常转向重复在固定时间段内检测驾驶员的瞌睡状态,例如,当变速杆被放置在超速行驶或顶部时 位置。 警报系统向驾驶员发出警报,以防止驾驶员增加嗜睡状态。 根据本发明的嗜睡警报系统包括:(a)转向信号发生器,其产生对应于方向盘旋转的角度变化的信号; (b)单调驾驶状态检测器,其检测并发出车辆在单调驾驶状态下行驶的信号; (c)鉴别器,其将来自所述转向信号发生器的转向信号电平的变化与固定时间段进行比较; 和(d)报警脉冲发生器,当来自指示固定时间段的转向信号变化的鉴别器的输出信号超过参考电压时,报警脉冲发生器响应于输入报警脉冲而将报警脉冲输出到报警电路中,产生报警 。

    • A receiver such as a liquid crystal display television receiver, which a user carries with him, is used for learning at sight which television stations at a destination supply broadcasting service. The receiver performs automatic tuning operation of television signal waves to search available television channels, stores searched available television channels in a memory device, and displays a list of the available stored television channels. The receiver displays the available television channels stored in the memory device, and successively receives the available television channels, thereby displaying the television programs for a predetermined period. The receiver is equipped with a memory in which local areas, local television stations in the areas, frequency data and network relations between key stations and the local television stations are memorized. When an area memorized in the memory is designated, a station-selecting guide information is displayed, which indicates a network relation between the local television stations and the key stations. The receiver selects an arbitrary television station and detect the signal receiving intensity, and stores data of the selected television station and the relevant signal receiving intensity in the memory device. The receiver displays a channel number and frequency data of the selected television station in a displaying manner associated with the detected signal receiving intensity.
    • 诸如用户携带的液晶显示电视接收机的接收机被用于在目的地学习目的地的哪个电视台提供广播服务。 接收机执行电视信号波的自动调谐操作以搜索可用的电视频道,将可用的电视频道存储在存储装置中,并且显示可用的存储的电视频道的列表。 接收机显示存储在存储装置中的可用电视频道,并且连续地接收可用的电视频道,从而以预定的时间段显示电视节目。 接收机配备有存储器,其中记录了本地区域,区域中的本地电视台,关键站和本地电视台之间的频率数据和网络关系。 当指定存储在存储器中的区域时,显示指示本地电视台和关键站之间的网络关系的选台指南信息。 接收机选择任意电视台并检测信号接收强度,并将所选择的电视台的数据和相关的信号接收强度存储在存储装置中。 接收机以与检测到的信号接收强度相关联的显示方式显示所选电视台的频道数和频率数据。
