摘要： Regarding the passive optical network (PON) system of the present invention, in an OLT, data of different bit rates is framed, and framed data rows are subjected to FEC encoding processing without changing the line up of the data, and a check bit is added to the end of the frame, and an optical signal that has been modulated in accordance with the data row to which the check bit has been added is transmitted to the optical transmission line. Then in an ONU that corresponds to a high speed bit rate to which an optical signal from the OLT has been applied via a power splitter, forward error correction of the reception data is performed. As a result in a PON system in which data of different bit rates coexist, the minimum reception rate of a high speed ONU can be improved without having an influence on a low speed ONU.

摘要： A semiconductor memory device enabling efficient repair of defects by using limited redundant memory while suppressing a drop of access speed accompanied with the repair of defects of the memory, wherein a first memory array is divided into a plurality of memory regions for each 16 word lines and wherein defective memory addresses in regions are stored in a second memory array. When a memory address for accessing the first memory array is input, the defective memory address of the memory region including the memory to be accessed is read out from the second memory array. In this way, the addresses of defective memory in 16 word lines worth of a memory region are stored in the second memory array 2, therefore addresses of a wider range of defective memory can be stored. For this reason, it becomes possible to repair defects occurring at random efficiently.

摘要： A scale is provided that switches a scale interval according to the degree of variation of sampled data and acquires a highly reliable weight value based on the switched scale interval. The scale is a digital scale which computes a weight value based on a predetermined scale interval, comprising data acquiring means, computation means, storage means, judging means, and scale interval switching means, wherein the data acquiring means acquires digital data of a load continuously, the computation means computes a predetermined number or a fluctuation range in a predetermined time of the acquired digital data, the storage means stores scale intervals set at multiple levels and allowable ranges of the fluctuation range that correspond to the scale intervals, the judging means determines the degree of variation of the digital data by comparing the computed fluctuation range with the allowable range of the fluctuation range which is stored for each scale interval, and the scale interval switching means switches the scale interval based on the determined degree of variation. Thus, the digital scale obviates need for a complicated and expensive filter associated with data processing and makes it possible to acquire a highly reliable weight value in a short measurement time. In particular, since the scale computes a body weight value based on a scale interval corresponding to the body motion of a subject in measurement of body weight, it requires no control of posture over a long period of time, can avoid a measurement error that the body weight value cannot be computed and is easy to use.

摘要： An abdomen width determiner determines an abdomen width value of a human subject. A memory stores a correlation between abdomen width values and waist circumferences of human beings. A waist circumference calculator calculates a waist circumference of the human subject on the basis of the abdomen width value determined by the abdomen width determiner and the correlation stored in the memory. The correlation stored in the memory may be expressed by the following regression formula: Y=aX+b where “Y” is a waist circumference of a human being, “X” is an abdomen width value of a human being, and “a” and “b” are constants.

摘要： A light source supplies optical signal to an optical switch and a detector detects light receiving level. A control unit changes a deflection control amount for changing an angle of a tilt mirror, and outputs the deflection control amount to a driving unit. When an input and an output ports are same, optical offset of the tilt mirror is calculated based on optimal angle at which the light detector detects an optimal point of the light receiving level. Whenever the input and the output port are different, a structure parameter of the tilt mirror is calculated based on the optical offset and the optimal angle. The optical offset and the structure parameter are stored in a memory as a test result.
