Abstract: A sensor appropriately detects the state of a fluid while reducing the effects of fluid temperature on fluid characteristics. The sensor includes a characteristics acquisition unit, a temperature measurement unit, a storage unit, and a correction unit. The characteristics acquisition unit acquires a characteristic value for an in-device fluid. The temperature measurement unit measures the in-device fluid temperature when the characteristics acquisition unit acquires the characteristic value. The storage unit stores a database registering an association between a pre-acquired characteristic of the in-device fluid and the in-device fluid temperature measured when the characteristic of the in-device fluid was pre-acquired. The correction unit corrects the characteristic value of the in-device fluid acquired by the characteristics acquisition unit based on the in-device fluid temperature measured by the temperature measurement unit and the database.

Abstract: Enabling an overturn preventing device to be installed even when a space between a top surface of an article and a ceiling is narrow. A bracket of an overturn preventing device is mounted to a piece of furniture to be prevented from overturn. The bracket has a lower part supporting a first base of a damper of the overturn preventing device at a position lower than a top surface of the furniture. The overturn preventing device can be easily installed even when a space between the top surface of the furniture and the ceiling is narrow.

Abstract: A sensor provides further detailed judgment with respect to the state of a fluid used in a device. The sensor includes a characteristics acquisition unit, a time measurement unit, and a state judgment unit. The characteristics acquisition unit acquires the dielectric constant and the conductivity of the fluid. The time measurement unit measures the time that elapses from the time point at which the fluid was charged to the device. The state judgment unit judges the state of the fluid based on the dielectric constant and the conductivity acquired by the characteristics acquisition unit and the time measured by the time measurement unit.

Abstract: A fluid state detection system that enables the state of a fluid to be readily detected is provided. A fluid state detection system for detecting the state of a fluid in a container includes a measurement window formed in a wall of the container, and a fluid state detection apparatus for detecting the state of the fluid. The fluid state detection apparatus includes a transmission unit, a receiving unit, and a detection unit. The transmission unit emits electromagnetic waves via the measurement window toward the fluid. The receiving unit receives reflected waves, transmitted waves, or re-radiated scattered waves of the electromagnetic waves emitted from the transmission unit via the measurement window toward the fluid. The detection unit detects the state of the fluid based on the electromagnetic waves emitted from the transmission unit and the electromagnetic waves received by the receiving unit.
