  • Patent number: 9817363
    Abstract: An image forming apparatus with a detachable fixing device that is capable of printing with high quality without printing wastefully. A storage unit stores identification information about a fixing device in association with an attribute of a sheet that is printable with the fixing device concerned. A control unit executes printing when the storage unit does not store an attribute of a sheet corresponding to a fixing device that is currently attached to the image forming apparatus. The control unit determines whether to execute printing according to an attribute of a sheet used in printing and an attribute of a sheet stored in the storage unit when the storage unit stores the attribute of the sheet corresponding to the fixing device that is currently attached to the image forming apparatus.

  • Patent number: 9818234
    Abstract: 3D shape reconstruction of objects including specular objects in which structured light patterns are projected toward an object which reflects the patterns onto multiple layers of EGlass arranged in spaced-apart relation with each other while each layer is in turn controlled to be in the diffuse mode with all others being in the transparent mode. Images are captured of the structured light pattern as reflected onto the EGlass layers by the mirror-like surface of the specular object. By projecting multiple different patterns, such as multiple different Gray code patterns, and by sequencing through each EGlass layer for each pattern, the 3D shape of the entirety of the visible surface of the object can be reconstructed by analysis of captured images of the distorted reflections of the patterns by the surface of the object. Embodiments are also described which can be used without reconfiguration for surface reconstruction of the shape of diffuse objects.
