A driving support apparatus of a vehicle supports driving of the vehicle, the vehicle includes a rudder angle varying device capable of changing a relative relation between a steering angle and a rudder angle. The driving support apparatus includes a following control device for controlling the rudder angle varying device such that the vehicle follows a target driving route; a steering angle specifying device for specifying the steering angle; and a judging device for judging whether or not overriding performed by a driver takes place on the basis of the specified steering angle and a reference steering angle which is the steering angle in making the vehicle follow the target driving route. The following control device stops the vehicle following for the target driving route if it is judged that the overriding takes place.

In an object detection apparatus, a captured image of a scene around a host vehicle, information indicating a travel state of the host vehicle, and information indicating a surrounding situation around the host vehicle are obtained; risk areas in each of which an object is likely to exist, and area risk degrees of the risk areas are estimated based on the obtained information; posture risk degrees of respective postures are estimated based on a relation between each of the risk areas and the postures of the object assumed to exist in the risk area; a window image is extracted from a search range in the captured image, which corresponds to each of the risk areas, according to descending order of overall risk degrees; and it is identified whether the window image is an image showing the object, by comparing an identification model with the window image.

A method and device for analyzing and treating tonal imperfections on human skin. The method has the steps of providing one or more nozzles and taking an image of skin adjacent the nozzles. A central processing unit calculates a plurality of local L values of the skin near nozzles and calculates a background L. The background L may be the arithmetic average, median, or mean of the plurality of local Ls near nozzles. Skin deviations are areas of skin where the absolute value of the difference between a local L and the background L, ΔL_M, is greater than a predetermined ΔL_S. Skin deviations are identified by this method and then treated with a treatment composition.

A face image detecting method, detecting system and detecting program are provided. After dividing the detection target area into a plurality of blocks and dimensionally compressing the area, feature vectors including a representative value in each block are calculated and then a discriminator detects whether the face image exists or not in the detection target area by using the feature vectors. The discriminator detects after an image feature quantity is dimensionally compressed to the extent of not damaging the feature of face image. Since the number of image feature items to be used for discrimination is substantially reduced from the number of pixels within the detection target area to that of blocks, the number of operations drastically decreases and a face image can be quickly detected.

Provided is an apparatus for detecting state of charge (SOC) of a battery. A voltage of a battery pack (100) is detected by voltage sensors (120-1) to (120-n). A determining unit (160) samples currents at times when the battery voltage reaches predetermined threshold voltages (Vth1, Vth2) respectively, and calculates an open end voltage (Vocv), based on representative values (I1, I2) of the sampled currents and threshold voltages (Vth1, Vth2). Furthermore, based on a correspondence relationship between the voltage (Vocv) and the state of charge (SOC) which is determined in advance, the state of charge (SOC) that corresponds to the calculated voltage (Vocv) is calculated.

A micro electromechanical ink jet printing system that has a cartridge having a body that defines a core, and a die that contains one or more nozzles. There is a treatment composition contained within the cartridge core. The system further includes a CPU that is programmable and can control the application of the treatment composition from within the cartridge core, through the one or more nozzles to human skin. Typically, the treatment composition will contain a skin treatment ingredient selected from the group consisting of particles, vitamins, yeast and yeast extracts, skin care actives, dyes, colorants and mixtures thereof. There may optionally be provided a bladder or foam block disposed within the cartridge core for suspending and regulating the flow of the treatment composition. The systems of this invention may include an applicator having an applicator head having one or more applicator nozzles which may be in a array. The applicator has a sensor that takes an image of at least 10 μm² of skin, the CPU analyzes the image to calculate one or more localized L values of individual pixels or group of pixels of the skin. Then the CPU compares the local L value to a predetermined background L value to identify skin deviations. A skin deviation occurs where the difference between the background L value and the local L value is greater than a predetermined ΔL_S value.
