  • Patent number: 8897859
    Abstract: A biosensor that includes a light transmissive electrocardiographic electrode and a light transmissive insulating film that detect an electrical signal relating to an electrocardiographic signal through capacitive coupling that are disposed above light emitting elements and a light receiving element that detect an optical detection signal relating to a photo-plethysmographic signal. When a user brings a finger into contact with a contact surface of the light transmissive insulating film, the electrical signal relating to the electrocardiographic signal is detected by the light transmissive electrocardiographic electrode. At the same time, reflected light emitted from the light emitting elements after being reflected from the user's finger are received by the light receiving element to detect an optical detection signal corresponding to the received reflected lights so that biological information is generated based on both the electrocardiographic signal and a photo-plethysmographic signal.

  • Publication number: 20140283591
    Abstract: A tire shape inspection method executes the following steps: first, as a teaching operation step, boundary lines of the bulge and dent marks are detected in a sample source image of a sample tire, a mask image is generated which denotes the boundary lines, regions are removed from the sample source image which correspond to the boundary lines which are denoted in the mask image, and a height offset image is generated which represents the heights of the remaining regions with one or more offset values. Next, as an inspection operation step, the height offset image is subtracted from an inspection image of the inspection tire, the boundary regions which the mask image represents are removed, and, on the basis of the obtained bulge/dent removal image, shape defects of the sidewall surfaces of the inspection tire are inspected.

  • Publication number: 20140261336
    Abstract: It is an object to suppress turbo lag, while suppressing a decrease in torque in an acceleration-transient state to a supercharged state, occurring owing to a rise in required load. In a prescribed steady state, an engine compression ratio ?m and ignition timing Tm are set so as to achieve a maximum thermal efficiency. In contrast, in a transient state from a non-supercharged state to a supercharged state, occurring owing to a rise in required load, the engine compression ratio is corrected to a higher compression ratio ?h and concurrently the ignition timing is corrected to a retarded timing value Th, in comparison with the engine compression ratio ?m and the ignition timing Tm during steady-state operation for the same load, thereby increasing exhaust energy due to a reduction in cooling loss and consequently suppressing a delay of response to a rise in supercharging pressure.
