    摘要: Systems, apparatus and methods are presented for sensing or estimating a tilt angle, in which a current flowing in an eccentric mass motor is sensed, and a detector circuit assesses the amplitude of a synchronous component of the motor current and provides an output signal or value indicating a tilt angle relative to a gravitational axis at least partially according to the amplitude of the synchronous component of the motor current.

    摘要: A liquid level detector for use in a pump control system comprises a chamber (20) for liquid, a liquid inlet (6) to the chamber (20), a liquid outlet (7) from the chamber and connectable to a pump, and a capacitive sensor comprising mutually spaced capacitive sensor elements (21, 22; 22, 23) forming a capacitance which is sensitive to permittivity within a region of the chamber proximate the capacitive sensor. The chamber is defined at least partially by a barrier member 25 and the capacitive sensor elements are provided on the barrier member outside the chamber.

    摘要: An optical sensor that a deterioration of detecting accuracy is suppressed is provided, and an optical sensor that an increase of the number of components and an increase of a physical constitution are suppressed is provided. The optical sensor has a light receiving element (120) having a light receiving surface (120a) to receives light, a detector (140) detecting an inclination of the light receiving surface in the vertical direction, and a correction portion (150a) correcting an output signal of the light receiving element (120) based on an output signal of the detector (140). Furthermore, the optical sensor includes a raindrop detector (210) detecting a raindrop, a light detector (230) detecting an incident light, and a storage part (250) storing these things. The raindrop detector (210) includes a light emitting element (211), a first light receiving element (212), and a first lens (213). The light detector (230) includes a second light receiving element (31) and a second lens (33).
