  • Patent number: 8700379
    Abstract: A method and apparatus for developing microcomputer-based systems. A controller model having at least one parameter is simulated and, similarly, a plant model having at least one parameter and controlled by the controller model is simulated. A user interface then has access to the parameters of the controller model and plant model and optionally suspends the execution of the controller model and plant model in response to a trigger event. The user interface determines the status of the controller model parameters and/or plant model parameters at the time of the trigger without altering the controller model parameters or plant model parameters or the program code of the controller model.

  • Patent number: 8150578
    Abstract: In a vehicle electronic system including a plurality of LSI boards, LSIS which cannot control a user interface such as image or audio directly issue a command for notifying a vehicle occupant of its own information via networks and an information control LSI receives the request to output a message. A mechanism for setting priority of processings regarding LSI status information notification to be lower than that of an apparatus control processing is provided in each of LSIs and networks so that real-time property of the apparatus control processing is maintained. In order to reduce network load regarding the LSI status information notification, a message content itself is stored in a memory in a vehicle information processing unit previously so that only an ID for identifying the message content is transmitted.

  • Patent number: 7956796
    Abstract: A system according to the invention detects location information of a vehicle by using a reflection strength change of an electromagnetic wave. The system incorporates a radiowave transmitter which emits a first radiowave, positional markers which generate unique reflection strengths and patterns of temporal changes in the reflection strength from the emitted first radiowave at respective absolute positions, a radiowave receiver which receives a second radiowave reflected by the positional marker and converts the second radiowave into a signal format for extracting location information to output the same, and a marker recognition device which obtains a location of the vehicle from the output of the radiowave receiver. Accordingly, a highly-precise location specification with a resolution smaller than or equal to 1 cm and a highly-reliable location specification which is not affected by slip and slide of the vehicle's wheels can be realized.

  • Publication number: 20090113186
    Abstract: A microcontroller and a controlling system having the same are provided, in which the increase in the program code for performing floating-point arithmetic, in particular, the increase in the amount of code due to a variable are suppressed, and the processing overhead for converting fixed-point data into floating-point data is reduced. The microcontroller includes a floating-point converter which inputs integer data and corresponding decimal point position data as fixed-point data and which converts the input data into floating-point data by acquiring a fraction part, an exponent part, and a sign of the floating type from the input data, and a floating-point arithmetic logic unit which receives the output of the floating-point converter and calculates the floating-point data. The floating-point converter acquires the exponent part by performing addition and subtraction of the decimal point position data and the shift amount of the fraction part to the integer data.

  • Patent number: 7254211
    Abstract: An apparatus for performing computed tomography having a radiation source and at least one radiation detector spaced from the radiation source and which generates an output signal representative of the strength of the received radiation from the radiation source. A part support for holding a plurality of parts is positioned in between the radiation source and the detectors. The part support is rotatably mounted about an axis generally perpendicular to a vector between the radiation source and the detectors so that, upon rotation of the part support, the radiation detectors generate an output signal corresponding to the internal structure of parts supported on the part support. A computer system receives the output signals from the detectors and, under program control, generates a report of the internal structure of the parts on the part support.

  • Patent number: 7253898
    Abstract: A system which detects droplets on a translucent surface having a camera which, upon activation, acquires an image of a portion of the surface. A radiation source, upon activation, illuminates the portion of the translucent surface while a control circuit selectively activates both the camera and the radiation source. A processor receives a captured image from the camera and, through image processing, generates an output signal representative of the number of droplets on the portion of the translucent surface.

  • Patent number: 7080549
    Abstract: A throttle position sensor for a throttle having a movable throttle element. The sensor includes an elongated electrically resistive strip having a first and second end. The first end of the strip is connected to a first voltage potential while the second end is electrically connected to a second voltage potential different from the first. An electrically conductive wiper is in sliding contact with the resistive strip. The wiper and resistive strip are relative to each other and one of the wiper or resistive strip is connected to the movable throttle element. Consequently, the position of the wiper relative to the strip varies proportionally with the position of the throttle element so that a voltage output from the wiper varies proportionally with the position of the movable throttle element. A circuit is associated with the sensor which determines the contact resistance between the wiper and the strip.
