    • In a PON system including a high-speed optical signal of a high transmission speed and a low-speed optical signal the speed of which is lower than that of the high-speed optical signal, the PON system employing TDMA system for upward signal transmission, an OLT controls transmission and reception of the low-speed optical signal and the high-speed optical signal and allocates a grant to a slave station unit connected to the OLT. The OLT includes: a traffic monitoring part for measuring the amount of traffic of data received from a high-speed ONU that is a slave station unit that makes communications using the high-speed optical signal; and a bandwidth allocating part for allocating a grant to a low-speed ONU on the basis of report information acquired from the low-speed ONU that is a slave station unit that makes communications using the low-speed optical signal, the bandwidth allocating part allocating a grant to the high-speed ONU on the basis of report information acquired from the high-speed ONU, a grant allocated in a previous cycle, and a result of measurement of the amount of traffic in the previous cycle acquired from the traffic monitoring part.

    • An ophthalmic laser irradiation apparatus for irradiating a laser beam onto a patient's eye capable of preventing a deviation of an irradiation position of the laser beam due to a change in a pupil (iris), and performing laser irradiation within high precision. The apparatus has an irradiation optical system for irradiating the laser beam onto the eye, an illumination unit, including an illumination light source, in which light intensity of visible illumination light onto the eye is adjustable, a detection unit which detects at least one of a pupil area and a pupil diameter of the eye, a setting unit which sets a reference value of at least one of the pupil area and the pupil diameter, and an informing unit which informs at least one of a detection value of the detection unit along with the set reference value and a comparison result thereof.
    • 一种用于将激光照射到患者眼睛上的眼科激光照射装置,其能够防止由于瞳孔(虹膜)的变化引起的激光束的照射位置的偏离,并且以高精度进行激光照射。 该装置具有用于将激光照射到眼睛上的照射光学系统,包括照明光源的照明单元,其中眼睛上的可见照明光的光强度可调节;检测单元,其检测至少一个 瞳孔区域和眼睛的瞳孔直径,设定单元,其设定瞳孔面积和瞳孔直径中的至少一个的参考值,以及通知单元,其将检测单元的检测值中的至少一个与 设定的参考值及其比较结果。
