Abstract: A weight checking apparatus is provided to prevent items that have not been properly checked from slipping through the weight checker. A weight checker 1 includes a weight conveyor 3, a loading sensor 6, a weighing portion 5, a weighing conveyor weight change monitoring means 9a, an item weight calculation means 9b, and a controller 9. The loading sensor 6 detects the loading of an item on the weighing conveyor 3. The weighing portion 4 detects the weight of the weighing conveyor 3. The controller 9 switches between the weighing conveyor weight change monitoring process and the item weight calculation process based on a detection signal from the loading sensor 6. The weighing conveyor weight change monitoring process monitors a change in the weight value of the weighing conveyor 3. The item weight calculation process calculates the weight of the item from the weight value detected by the weighing portion 5.

Abstract: The object of the present invention is to provide a position detection apparatus that is able to easily detect self-position during autonomous movement by a humanoid robot that moves by the use of legs or automobile.

Abstract: A network system includes a plurality of vehicle-mounted, microcomputer-based electronic devices each having & distributed operating system for performing data communication and distributed processes among the electronic devices. By virtue of the distributed operating system, information resources and hardware resources can be used in common by two or more of the vehicle-mounted electronic devices. Thus the network system has a higher level of network transparency. Because the electronic devices can operate independently and they are interconnected by a common interface called network, a revision to the program of one of the electronic devices or entry of a new electronic device to the network system does not induce tedious and time-consuming version-up of the program of any other electronic device.

Abstract: A control device of an autonomously moving body according to the present invention comprises at least one image pickup unit which picks up the image of a moving road of an automatically moving body; an image processing unit which processes a plurality of image data outputted from the image pickup unit and detects and outputs the condition of said moving read, or an outside information obtaining unit which obtains environmental information other than image; a storage means which stores data outputted from said image processing unit or said outside information obtaining means; a data control section which corrects said data stored in said storage means to data of an arbitrary time and position; a data evaluating section which integrates a plurality of data outputted from said data control section into one moving road data; and a control section which controls the movement of the autonomously moving body according to the moving road data outputted from said data evaluating section.
