Along with digitization of information, it has become more easy to share and use information over a broad range. It is very important to manage digital documents and documents obtained by printing the digital documents. After completion of a conference, each participant makes an MFP read a document image of a distributed reference. The MFP searches for a data file which matches the read document image with reference to information in a storage unit, and deletes the detected data file. If the number of pages of the read image is short, the data file cannot be detected, or the read document image shows a partial loss, the MFP generates a warning. Upon reception of a collection completion message, the MFP checks with reference to information in the storage unit if all data files associated with the conference are deleted. If a data file to be deleted still remains and that data file is printed, the MFP generates a warning.

The invention provides an integrative compressing method and device of an image. The integrative compressing method comprises at least one lossless encoding method and at least one loss encoding method. A basic encoding unit is an encoding sub-block with fixed size. For each encoding sub-block, both loss and lossless encoding methods are used for encoding the encoding sub-blocks for one time, saving encoding results with least R-D (Rate-Distortion) cost function values and marking the corresponding encoding method as an optimal encoding method. In the whole compression process, partial lossless compression and partial loss compression are carried out with ultrahigh image quality. For the lossless encoding which carries out compression by using a dictionary, the data in the dictionary is from N-byte data which is encoded by using the lossless method recently, and the traditional image compression method is only suitable for some image content. Through combining the plurality of lossless and loss encoding methods, for different image contents, the proper encoding method is selected from the view of acquiring the optimal encoding R-D performance, thereby the invention is suitable for compressing the image including the plurality of contents.

Control features for a wind turbine that control the turbine over a range of wind speeds and under triggering conditions with reduced noise, cost, and reliability issues associated with other such controls. Control is accomplished via control electronics, which adjust the torque produced by the electrical output generation device (e.g., alternator) within the wind turbine. During normal operation, torque is adjusted for optimum aerodynamic performance and maximum output of power. In winds above rated power, the control circuit regulates torque to lower aerodynamic performance, as necessary to maintain desired power level output. In triggering conditions, such as during simultaneous control circuit failure and loss of some portion of the electrical output generation device in extreme winds, wind turbine control is accomplished by increasing torque (e.g., via a separate controller) from the electrical output generation device via shorting of windings, so as to cause retardation of blade rotation.

The present invention is aimed at techniques for detecting the “partial loss” of an upper layer frame. One technique envisions a detection platform adapted to determine whether a packet is a final packet for a particular upper layer frame.

A transmission platform then sends a signal indicative of whether the packets received without transmission errors constitute the particular upper layer frame so that lost packets can be retransmitted quickly.
