Abstract: The present disclosure provides an electronic component. The electronic component includes a cavity, a membrane, deformable in accordance with a difference between a pressure inside the cavity and a pressure outside the cavity and an arithmetic circuit. The membrane includes an opposing portion facing the cavity. One of a peripheral part and a central part of the opposing portion is a thin portion, and another one is a thick portion thicker than the thin portion. The arithmetic circuit is configured to detect a pressure value in a first zone based on a first output value in the thin portion, and detect a pressure value in a second zone higher than the first zone based on a second output value in the thick portion.

Abstract: A MEMS module includes a MEMS element provided with a substrate in which a hollow portion is formed, the MEMS element including a movable portion of the substrate which covers the hollow portion and has a thickness that allows a shape of the movable portion to be deformable, a first gauge resistor arranged on the substrate such that at least a portion of the first gauge resistor overlaps with the hollow portion, and a second gauge resistor arranged on the substrate in a region surrounding the first gauge resistor without overlapping with the hollow portion, and an electronic component configured to correct detection information of the MEMS element by using a first electrical signal detected by the first gauge resistor and a second electrical signal detected by the second gauge resistor and calculate an amount of change in air pressure.

Abstract: A MEMS module includes: a MEMS element provided with a substrate in which a hollow portion is formed, and including a movable portion, which is a part of the substrate, around the hollow portion, the movable portion having a thickness whose shape is changeable by an air pressure difference between an air pressure inside the hollow portion and an air pressure outside the substrate; and an electronic component, to which an output signal of the MEMS element is inputted, formed on the substrate, wherein the electronic component and the MEMS element are spaced apart from each other in a direction perpendicular to a thickness direction of the movable portion.

Abstract: A MEMS module includes: a first MEMS element and a second MEMS element each including a movable portion which is a portion of a substrate including a hollow portion formed therein, the movable portion configured to warp in shape according to an air pressure difference between an internal air pressure inside the hollow portion and an external air pressure outside the hollow portion; and an electronic component configured to calculate a change in external air pressure outside the substrate by using an amount of warpage of the movable portion of at least one of the first MEMS element and the second MEMS element, wherein the amount of warpage of the movable portion according to the external air pressure differs between the first MEMS element and the second MEMS element.

Abstract: A device includes an electric power usage measurement unit, a time variation calculation unit, an electrical-appliance type identification unit, a corresponding likelihood estimation unit, and an operation-status estimation unit. The calculation unit calculates jump electric power. The identification unit judges, from the jump electric power, whether a new electrical appliance is added to or an extra type is deleted from a type list. The corresponding likelihood estimation unit estimates the likelihood of events to which electrical appliance up and down jumps correspond.
