    • An infrared object detector, especially for an air conditioner is provided with a light receiving unit including a light block between a pair of hemispherical Fresnel lenses arranged in parallel on a printed circuit board, so that light receiving views intersect each other to thereby define three detection areas. From a signal output from the light receiving unit, the distance to a detected object is determined through a signal processing circuit and a program built in a microcomputer. The rotational speed of a fan in the air conditioner is classified into three stages according to the determined distance, and a command is issued for controlling the operation of an air conditioner according to the number, movements, movement degrees to persons. Therefore, the airflow of the air conditioner is controlled based on the command, thereby performing an optimum air conditioning. Further, the infrared object detector can be applied to a camcorder or a camera, to determine the distance to an object more accurately.
    • 一种特别用于空调的红外对象检测器设置有光接收单元,该光接收单元包括在印刷电路板上平行布置的一对半球形菲涅尔透镜之间的光块,使得光接收视图彼此相交,从而限定三个检测 地区 从光接收单元输出的信号,通过信号处理电路和内置于微型计算机中的程序来确定到被检测物体的距离。 根据所确定的距离将空调机中的风扇的旋转速度分为三个阶段,并且发出用于根据对人的数量,移动,移动程度来控制空调的操作的命令。 因此,基于命令来控制空调的气流,从而进行最佳的空调。 此外,红外对象检测器可以应用于摄像机或照相机,以更准确地确定到物体的距离。

    • A multi-functional peripheral device and a method thereof that indicates a shortage of printing media. In a method of indicating a shortage of printing media in a multi-functional peripheral which receives a predetermined data including fax data from an external source and prints the received data, the method includes printing the received fax data on a printing medium; determining through a predetermined fax protocol data which is received from the external source at the time of completing printing on a current printout page, as to whether there is fax data to be printed on the next printing medium; when there is fax data to be printed on the next printing medium, determining by using a sensor as to whether there is a printing medium to print out the fax data; and when there is no printing medium, displaying a message on the lower portion of the current printout page, indicating that there is more fax data to be printed, and storing the fax data in a memory. The fact that there is fax data waiting to be printed, can be indicated in the lower portion of the last page of the printouts such that the user is saved from inconvenient processes such as contacting the external source to check whether all the intended pages are safely received or not.
    • 一种表示打印介质不足的多功能外围设备及其方法。 在一种指示在多功能外围设备中缺少打印介质的方法中,该多功能外围设备接收包括来自外部源的传真数据的预定数据并打印所接收的数据,该方法包括在接收到的打印介质上打印所接收的传真数据; 通过在当前打印输出页面上完成打印时从外部源接收的预定传真协议数据确定是否存在要在下一打印介质上打印的传真数据; 当在下一个打印介质上存在要打印的传真数据时,通过使用传感器确定是否有打印介质来打印传真数据; 并且当没有打印介质时,在当前打印输出页面的下部显示消息,指示存在要打印的更多传真数据,并将传真数据存储在存储器中。 存在等待打印的传真数据的事实可以在打印件的最后一页的下部指示,使得用户从诸如联系外部源的不方便的处理中保存用户以检查所有预期页面是否安全 收到还是不收
