  • Publication number: 20150371126
    Abstract: An image forming apparatus includes an image forming unit, a detector, an avoidance process memory, a print data memory, and an acceptor. The image forming unit receives a print instruction including print data and a print setting and forms an image on a sheet. The detector analyzes the print data and/or the print setting in the print instruction, and detects an error that is an unprocessable or invalid instruction. The avoidance process memory stores an error avoidance process of avoiding the error and enabling execution of image formation, in association with the print instruction including the error. The print data memory stores the print data in the print instruction including the error. The acceptor accepts an instruction to avoid the error and to execute image formation, in accordance with the stored error avoidance process and the stored print data.

  • Patent number: 8994823
    Abstract: 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.

  • Patent number: 8005243
    Abstract: A parameter display portion of an acoustic signal processing apparatus (mixer) according to the present invention displays a setting of a parameter (channel group setting parameter) by use of a plurality of light-emitting display elements (LED) La through Lc. While the acoustic signal processing apparatus is under operating conditions with a setting of the parameter being established through a setting operation of an operator (on-switch) Bt, the display elements La through Lc in the entire parameter-establishable range are kept in display action. The parameter display portion is controlled such that, during the display action, the display element [(2)=La, (3)=Lb, (4)=Lc] corresponding to the established setting is displayed in the first display mode, while the other display elements [(2)=Lb and Lc, (3)=La and Lc, (4)=La and Lb] excluded from the established setting being displayed in the second display mode.

  • Patent number: 7860257
    Abstract: In order to define current states of a mixer, a set of first-type data (scene data) that define processing to be performed on a signal second-type data and a set of second-type data (snapshot data) comprising a group of parameters that define functions or displaying styles of operators or displays are stored in a current area. Storage area or memory is provided for preserving the second-type data, so that the second-type data can be written from the current area into the storage area or recalled from the storage area into the current area in accordance with a user instruction.

  • Patent number: 7561934
    Abstract: In an audio signal processing device which processes audio signals and outputs the audio signals, setting controls, such as filter controls, for setting values of parameters for the signal processing and a display for presenting information by the presence or absence and the style of lighting of LEDs is provided, in which when scene data stored in a scene memory is loaded, the display style of the display is made different in accordance with match/mismatch between a current set value of the parameter and the value of the parameter relating to the loaded scene data. Alternatively, the display is made to simultaneously present the loaded value and the value at the time of the loading in different display styles.

  • Patent number: 7555045
    Abstract: A picture decoding section starts to decode a bit-stream for one picture when a decoding start command is supplied from a decoding start command generating section, and outputs a decoding completion command when the decoding is completed. Decoded picture data is stored in a decoding frame buffer. The decoding frame buffer outputs a bufferfull notification when a certain quantity of picture data is stored. The decoding start command generating section outputs the decoding start command to the picture decoding section when a decoding completion command is outputted from the picture decoding section and the bufferfull notification is not outputted from the decoding frame buffer.

  • Patent number: 7543797
    Abstract: A valve device is provided. The valve device of the present invention includes a planetary component and two valve plates. The two valve plates are disposed on a hole portion of the planetary component opposite to each other, so as to provide a quick opening and closing with a relatively high opening and closing speed, and to reduce the space occupied. Therefore, the provided valve device does not need to perform adjustment (processing) to reduce the operating force on the sluice valve or to assure the closing function of the valve. Further, the function and the producibility of the valve are improved significantly.
