  • Patent number: 10264226
    Abstract: Light is made more expressive by a simple configuration of an illumination device. An illumination device (10) includes: a projection section on which beams of light which beams are emitted from a first LED (1A) and a second LED (1B), respectively, are to be projected; and a light emission control section (3) configured to control the first LED (1A) and the second LED (1B) so as to temporally change intensities of the beams of light. The first LED (1A) and the second LED (1B) are provided so that the beams of light which beams are emitted from the first LED (1A) and the second LED (1B), respectively, overlap in part in the projection section, and assuming that a part of the projection section in which part the beams of light overlap is an overlapping part, the light emission control section (3) changes the intensities of the beams of light so that at least any one of a size, a location, and a shape of the overlapping part is temporally changed.

  • Publication number: 20180081751
    Abstract: Business transactions and the nodes processing the transactions may be monitored. Actions may be applied to one or more nodes when a performance issue is detected. A performance issue may relate to a metric associated with a transaction or node that processes the transaction. If a performance metric does not satisfy a health rule, the policy determines which action should be performed to correct the performance of the node. The corrective action may be applied to a node other than the node at which the performance metric is associated with. For example, if a performance metric for a first node does not satisfy a threshold, the corrective action may be applied to a second node. When a solution applied to a second node is found to correct the problem in first node, the solution may be applied to the other nodes experiencing the same problem.

  • Patent number: 9885979
    Abstract: A toner filling apparatus includes a filling tank, a toner filling path forming member, a toner fluidizing unit, a filling path opening/closing unit and a container room sucking unit. The toner filling path forming member is in communication with the filling tank and forms a toner filling path connected to the toner container. The container room sucking unit sucks air from the toner container through a filter member which is impermeable to the toner but permeable to air. When the toner fluidizing unit fluidizes the toner in the filling tank and the filling path opening/closing unit opens the toner filling path so as to load the toner to the toner container, the container room sucking unit reduces a pressure in the toner container to a negative pressure so as to draw in the toner into the toner container.
