The notification section notifies an error upon the orientation determining section determining that the orientation detecting section does not detect orientation alternation between the first orientation and the second orientation.

Abstract: A printing system, when information about an image forming apparatus is registered in a printing service apparatus or when information about the image forming apparatus already registered in the printing service apparatus is updated, determines whether firmware installed in the image forming apparatus corresponds to the printing service apparatus. If the firmware installed in the image forming apparatus is determined not to correspond, the printing system determines whether firmware corresponding to the printing service apparatus exists in firmware of the image forming apparatus distributed by the distribution server. If the firmware corresponding to the printing service apparatus is determined to exist and when that firmware is distributed from the distribution server to the image forming apparatus, the printing system installs the distributed firmware.

Abstract: A method for correcting an image acquired by a hand-held scanning device. A binarized image of an acquired image is cropped by removing columns on the left end and on the right end of only first components. A work image is created from the cropped image by replacing in each row of components series of first components smaller than a predetermined distance with series of second components. In the work image, a central line is identified. The identified central line in the work image is used to identify the corresponding central line in the cropped image forming a central line image, and in the central line image, the central text line is straightened.

Abstract: A system and method and system for receiving communications signals coded at transmission in a frequency hopping waveform includes a sensor that receives acoustic data. A detector joined to the sensor receives the data and separates signals from background noise. Logic determines when the signal ends. Clusters of signals are processed and grouped into combinations of symbols. A computer translates these symbols into messages using a codebook. When multiple possibilities exist, the message is selected from the codebook that maximizes a similarity score. Additional logic is provided to handle situations where unwanted signals are mixed into an otherwise valid symbol sequence, to find the best subset of signals forming a valid message. Selected messages are provided as output to users. In further details, the detector filters the acoustic data and transforms it to the frequency domain. A power spectrum is calculated for detecting signals in specific frequency bands.
