  • Publication number: 20120216208
    Abstract: An in-car-use multi-application execution device is provided that ensures safety while maintaining convenience by securing operation of a plurality of applications and suppressing occurrence of a termination process within a limited processing capacity without degrading a real-time feature. The in-car-use multi-application execution device dynamically predicts a processing time for each application, and schedules each application on the basis of the predicted processing time. If it is determined that an application failing to complete a process in a prescribed cycle exists as a result of the scheduling, a process is executed that terminates the application or degrades the function of the application on the basis of a preset priority order.

  • Patent number: 7989330
    Abstract: After etching a polysilicon film, when a protective film made of a carbon polymer is formed on a sidewall of the polysilicon film using plasma containing carbons, a metallic material as a lower film is etched using plasma containing a halogen gas under an etching condition in which volatility is improved due to the rise in a wafer temperature or the low pressure of a processing pressure, thereby preventing a side etching and unevenness of a sidewall of the polysilicon film. Further, by using the protective film made of a carbon polymer, metallic substances scattered at the time of etching the metallic material are not directly attached to the polysilicon film, but can be simply removed along with the protective film made of a carbon polymer in an asking step.

  • Patent number: 7957559
    Abstract: In conventional systems using an onboard camera disposed rearward of a vehicle for recognizing an object surrounding the vehicle, the object is recognized by the camera disposed rearward of the vehicle. In the image recognized by the camera, a road surface marking taken by the camera appears at a lower end of a screen of the image, which makes it difficult to predict a specific position in the screen from which the road surface marking appears. Further, an angle of depression of the camera is large, and it is a short period of time to acquire the object. Therefore, it is difficult to improve a recognition rate and to reduce false recognition. Results of recognition (type, position, angle, recognition time) made by a camera disposed forward of the vehicle, are used to predict a specific timing and a specific position of a field of view of a camera disposed rearward of the vehicle, at which the object appears.

  • Patent number: 7782179
    Abstract: An obstacle detection apparatus more accurately detects a moving obstacle present around a motor vehicle. With this system, desired feature quantities of an obstacle present in a coverage of a first sensor are calculated and then stored into a storage device, and when the obstacle moves from the coverage of the first sensor to a coverage of a second sensor, a relative distance to the obstacle is calculated from the above-stored feature quantities of the obstacle and from the desired feature quantities of the obstacle, obtained by analyzing the recognition results of the second sensor that have been processed by a processor which processes the recognition results.

  • Publication number: 20080084165
    Abstract: The present invention provides a headlight control apparatus which suppresses a feeling of strangeness given to a driver of an own vehicle by hunting due to reflector light while preventing a preceding vehicle and an on-coming vehicle from being dazzled, based on a video image obtained by a camera. The headlight is controlled by detecting the position of a light spot in the image captured by the camera to perform irradiation with a pattern which reduces the light quantity of a certain area above the detected light spot. Thereby, even if hunting occurs due to the reflector light, the irradiation light quantity of an entire irradiation area of the headlight does not vary, but only the irradiation light quantity for a partial area above a reflector varies, and therefore, the feeling of strangeness given to the driver can be suppressed.
