Abstract: An object amount detection device includes a container configured to contain a solidifiable liquid object, an electrode extending in a vertical direction in the container, and configured to allow for detection of a change in capacitance accompanying a positional change in the vertical direction of a liquid surface of the object or an exterior surface of the object having been solidified, and a processor configured to execute program instructions stored in a memory to detect continuously or intermittently, based on the capacitance of the electrode, a position of the liquid surface or the exterior surface of the object in the container, to obtain a permittivity of the object from the capacitance of the electrode, and to determine a state of the object based on the obtained permittivity.

Abstract: Operation input device with few gesture operation erroneous detections is provided. Operation input device includes substrate; plurality of detecting electrodes provided on substrate surface; detecting unit detecting capacitance occurring between each detecting electrode and operating body upon operating body being brought close to substrate; and determining unit determining whether gesture operation by operating body has been performed. Detecting electrodes include first and second electrodes of which capacitance values decrease/increase to match amount of movement of operating body when operating body is moved in longer direction. Upon sensing of operation of moving operating body after being stopped relative to detecting electrodes, or operation of stopping operating body after being moved relative to detecting electrodes, gesture operation by operating body is determined to have been performed. Operating body is determined to be stopped when changes in sum of, and ratio between, capacitance values of first and second electrodes are ≤predetermined values.

Abstract: An operation device includes a housing, an operation member, and a detector. The housing includes an electrically conductive portion on a surface thereof. The operation member is supported by the housing such that the operation member is movable in response to an operation by an operation body, and is configured to be capacitively coupled to the operation body and to the electrically conductive portion. The detector is configured to detect whether the operation body is in proximity to the operation member based on a change in capacitance at the electrically conductive portion.
