Abstract: A wireless communication device of the present disclosure, to which an electric power measurement value is input that is measured in an electric power measurer to which a power supply side power line and a load side power line are connected, includes a first antenna element that transmits and receives radio waves and a wireless circuit connected to the first antenna element. The first antenna element has a longitudinal side perpendicular to a line along which the power supply side power line and the load side power line extend.

Abstract: A wireless communication device includes: flow-rate measuring unit connected to fluid pipe; and first antenna element that transmits and receives a radio wave. First antenna element has a longer side orthogonal to an axis of fluid pipe. According to this configuration, a direction of a plane of polarization of a radio wave radiated from first antenna element is orthogonal to fluid pipe. Thus, the radio wave is not reflected by fluid pipe but propagates in a direction toward fluid pipe, namely, in a rear surface direction of a meter including the wireless communication device.

Abstract: A projection system is configured to project first and second projection images, with end portions of the first and second projection images overlapping. The projection system includes a first projector projecting the first projection image and a second projector projecting the second projection image. The first projector acquires first projection image data and a first control signal, the first projection image data representing the first projection image that is a clipping of an original projection image, the first control signal being linked to the first projection image data and being for controlling driving of the first projector. The second projector acquires second projection image data and a second control signal, the second projection image data representing the second projection image that is a clipping of the original projection image, the second control signal being linked to the second projection image data and being for controlling driving of the second projector.

Abstract: A gas meter includes a flow rate measurer that is located at a gas passage and measures a flow rate of the gas flowing through the passage, a self-diagnoser that performs self-diagnosis, and a vibration detector that detects vibration. The gas meter also includes a calculator that calculates an earthquake index value based on the detected vibration, the earthquake index value indicating the scale of an earthquake, a blocker that switches from an open state to a closed state of the passage when the earthquake index value is not less than a predetermined value, and a restoring method determiner that, when the blocker is in the closed state, determines a restoring method of restoring the blocker from the closed state to the open state based on a result of the diagnosis by the self-diagnoser and the earthquake index value.
