    • The invention provides an apparatus for processing an image of a face, capable of quickly and correctly detecting eyes not only under artificial illumination but also under sunlight regardless of the direction or altitude of the sun and regardless of circumstance conditions such as sunlight filtering down through trees, and still regardless of the variation in the face shape from person to person. An image of the face of a car driver is taken by a camera, and input to image signal input means. Gray level conversion means performs signal level conversion of picture elements of the face image received via the image signal input means in such a manner as to extract black-level areas smaller at least in the dimension along one image axis parallel or nearly parallel to the vertical direction of a face than a predefined length corresponding to the up-to-down width of an eye, thereby extracting black level areas having a size nearly equal to or less than the up-to-down width of the eye and thus extracting characteristic feature areas such as eyes, eyebrows, nares, and line between lips from the input face image. Variable binarization means converts the characteristic feature image into a binary image. Eye searching area setting means sets eye searching areas in the binary image. Candidate area setting means sets eye candidate areas in the eye searching areas. Eye area detection means detects eye areas from the eye candidate areas.

    • A tubular single-layer winding coil is installed on the outer periphery of a thin wall portion of a cylindrical container case and a columnar electrode is provided at the center of the inside of the cylindrical container case. A fuel channel is formed between the coil and the electrode so that the permittivity of fuel flowing through the fuel channel is detected from the electrostatic capacity therebetween. Further, variation of the electrostatic capacity due to the temperature characteristics of the fuel is compensated by the temperature characteristics of the permittivity of the thin wall portion of the sensor unit. Furthermore, variation of the electrostatic capacity due to the temperature characteristics of the fuel is compensated by the temperature compensation capacitor which is connected with the single layer winding coil in parallel.

    • A liquid content detecting device is provided which can detect the contents of liquid components such as alcohol in a mixed fuel (both regular and premium gasolines) with a high degree of preciseness at all times over the entire operating temperature range in which the device is used. A refractive index sensor senses the refractive index of a liquid mixture which includes N kinds of liquid components. A liquid-kine identifying means identifies the kind of each of the liquid components. A temperature sensor senses the temperature of the liquid mixture. A liquid content calculator stores a temperature-dependent refractive index characteristic of various kinds of liquids including the liquid components in advance. The liquid content calculator is operable to select the temperature-dependent refractive index characteristic of each of the liquid components, and calculate the contents of the liquid components in the liquid mixture on the basis of the thus selected temperature-dependent refractive index characteristics of the liquid components and the refractive indexes of the liquid mixture, which are sensed by the refractive index sensor at (N-1) different temperatures.

    • The present invention is directed to a device for detecting alcoholic content in a fuel by finding its refractive index, which is of such a construction that a refractive interface for the fuel is formed at an intermediate portion of a light transmission body; a light emitting element is provided at one end of the light transmission body, from which incident light is introduced into said refractive interface; and a single dimensional light position sensing detector is provided at the other end of the light transmitting body, into which the light refracted at the refractive interface is introduced. Alternatively, the device is of such a construction that a light emitting element and a single dimensional light position sensing detector are provided at one end of a light transmission body; a refractive interface and a reflecting surface are provided at the other end of the light transmission body, wherein an incident light from the light emitting element, which has entered into the refractive interface and has been refracted there, is reflected at the reflecting surface, after which the reflected light is again caused to enter into the refractive interface, and is subsequently caused to enter into the single dimensional light position sensing detector.
