    • When a wireless communication station, which is about to communicate while intermittently receiving a multicast service, transmits, to an access point, a request packet describing information on the multicast service and an intermittent reception request, the access point describes, in a packet, intermittent reception timing information corresponding to the multicast service information described in this request packet, and replies with this packet to the wireless communication station. The wireless communication station reads the intermittent reception timing information from the received packet, and performs transition to the Awake state or the Doze state according to this intermittent reception timing. The access point, on the other hand, transmits the multicast packet to the wireless communication station according to the intermittent reception timing.
    • 当间歇地接收多播服务时要通信的无线通信站向接入点发送描述关于多播服务的信息的请求分组和间歇接收请求时,接入点在分组中描述间歇性 与该请求分组中描述的多播服务信息相对应的接收定时信息,并且向该无线通信台回复该分组。 无线通信站从接收到的分组中读取间歇接收定时信息,根据该间歇接收定时,进行到唤醒状态或打盹状态的切换。 另一方面,接入点根据间歇接收定时将组播分组发送到无线通信台。

    • A system for transmission of signals between modules wherein, for example, it is possible to transmit reliably, between modules, information relating to, for example, the actuation of safety devices. A transmission module for transmitting a pulse signal of a specific period, which indicates the existence of information, generates, in time division, pulse signals by a plurality of signal generating units that are provided in parallel, and then combines these pulse signals into a single time series pulse signal. Then an attempt is made to output this pulse signal towards a receiving-side module through a relay for controlling the output, and the signals appearing at a normally-open terminal and at a normally-closed terminal of the relay are monitored to determine whether or not there is a failure, where the generation of the pulse signal is stopped when a failure is detected.
    • 用于在模块之间传输信号的系统,其中例如可以在模块之间可靠地传输信息,例如关于安全装置的致动的信息。 用于发送表示存在信息的特定时段的脉冲信号的发送模块通过并行提供的多个信号产生单元在时分中产生脉冲信号,然后将这些脉冲信号组合成单个 时间序列脉冲信号。 然后尝试通过用于控制输出的继电器将该脉冲信号输出到接收侧模块,并且监视出现在继电器的常开端子和常闭端子处的信号,以确定是否或 没有发生故障,其中当检测到故障时脉冲信号的产生被停止。

    • An image capture device includes: an imager for imaging an object and generating image data; an image file generator for generating an image file by adding, to the image data generated by the imager, a header portion which stores at least one type of information concerning shooting circumstances; a timer for outputting information indicating a current time; and a manipulation section which is used to set period information specifying a period. The image file generator changes the type of information to be stored in the header portion depending on whether a time of imaging as indicated by the information which is output from the timer at the time of the imaging falls within the period specified by the period information.
