  • Patent number: 9689660
    Abstract: An object of this invention is to sense a transient displacement of the blade position to thereby detect abnormalities early. The invention includes: one or more first sensors mounted so as to be removable from an outer surface of a casing opposed to blade tips; a second sensor for acquiring a signal from a fixed point on a rotor shaft of the blades; a section configured to extract data groups from an output signal of the first sensor on the basis of information acquired by the second sensor; a section configured to average the data groups; a section configured to determine thresholds from averaged data obtained under a healthy condition; and an assessing section configured to compare magnitude of the thresholds and sensor signals obtained during blade status monitoring. Since a transient displacement of blade position can be sensed, abnormalities can be detected early in this invention. This early detection, in turn, enables a rotation to be stopped during an initial phase of blade damage.

  • Publication number: 20120326614
    Abstract: According to one embodiment, a luminaire includes a dim lighting circuit, an emergency unit, a dimming-signal input section, and a dimming control circuit. The dim lighting circuit dimly lights a light source at a dimming ratio corresponding to a dimming signal. The emergency unit includes a charging circuit for charging a battery with an external power supply in a normal time and supplies a power supply of the battery to the dim lighting circuit in an emergency. The dimming-signal input section receives the input of the dimming signal from the outside. The dimming control circuit gives the dimming signal input from the dimming-signal input section to the dim lighting circuit in a normal time and gives a dimming signal having a dimming ratio for an emergency to the dim lighting circuit in an emergency.
