Abstract: A display panel is adapted to display at least one meter image including a pointer image constituting a pointer and a mark image constituting a mark that the pointer is adapted to point to. A processor controls the display state of the pointer image. The processor causes the pointer image to be displayed on the display panel when the pointer image does not point to the mark image and causes the pointer image to be displayed on the display panel in a second display mode when the pointer image points to the mark image. The first display mode and the second display mode are different.

Abstract: A distributed consensus method for performing data consensus processing in a distributed system that couples one or more client apparatuses and a plurality of server apparatuses via a network, the method including a step in which each server apparatus performs data operation according to a predetermined distributed consensus algorithm, a step in which an auxiliary consensus device, which is an auxiliary device that assists in reaching a consensus in the event of a failure in response to a request from each server apparatus, decides an auxiliary consensus decided value, and a step in which the auxiliary consensus decided value is caused to take precedence over the decided value of the distributed consensus algorithm under conditions under which the auxiliary consensus decided value decided by the auxiliary consensus device and the decided value decided by the distributed consensus algorithm can conflict with each other.

Abstract: Upon receiving an input of data, an input unit transmits a time notification to another input unit and transmits a data notification including the input clock time to a storage unit. Upon receiving a time notification from another input unit, the input unit transmits an empty notification including the input clock time to the storage unit to indicate there is no input before the input clock time. Upon receiving the data notification from an input unit having received the input of data and receiving the notification from the other input unit, the storage unit broadcasts the data in order, assuming that consensus of the plurality of storage units is confirmed. When adding an input unit to a computer system, a control device causes the storage unit to start confirming the consensus including the joining input unit after a window interval has elapsed after the joining input unit starts operation.

Abstract: A luminance adjustment system adjusts luminance of image display in a display device. The luminance adjustment system includes a controller that changes the luminance in accordance with a value of illuminance in a target space, The controller has, as operation modes, a gradual change mode in which the luminance with respect to the value of illuminance is changed in a first time, and an abrupt change mode in which the luminance with respect to the value of illuminance is changed in a second time being shorter than the first time. The controller makes switching from the gradual change mode to the abrupt change mode with a sign of an abrupt change in illuminance in the target space taken as a trigger, and then operates in the abrupt change mode for at least a fixed time after the switching.
