A method of monitoring supply chain activity throughout a plurality of supply chain sites includes extracting, at each supply chain site, supply-related data to be monitored. The data is maintained in plural formats at the supply chain sites, and translated the data to a common format. The extracted data is then uploaded to and collected, from each supply chain site, to a data collection center or site. Upon a user request, a portion of the collected data is formatted, at the data collection site, into one of a plurality of views, responsive to criteria selected by the user, for presentation to the user, the portion of formatted data being dependent on access rights granted to the user's supply chain site. Finally, the formatted data view is published to the user's supply chain site. The data collection center comprises a data collector in which the uploaded data is stored, and a publisher for publishing data from the data collector upon request. Each supply chain site has a data storage device for maintaining its own supply-chain data, a data transfer engine (DTE), for transferring the supply-chain data to the data collection center, input means for allowing a user to query the data collector, and a display for displaying data published by the publisher in response to a query. The inbound data received from the multiple supply chain sites is monitored at the data collection site. If a problem condition is detected, such as a forecasted or present shortage or surplus, an alert is asserted, for example, by highlighting an Alert indicator, such as an Alert tab, on a user screen. Upon selection of the highlighted Alert indicator by a user, details of the detected problem condition are displayed.

The ink cartridge has a first detection target portion for detecting ink level and a second detection target portion for identifying the type of an ink cartridge. The ink level detection device uses an optical sensor to scan the first and second detection target portions of the ink cartridge, and detects ink level and the type of the ink cartridge, that is, whether the ink cartridge is containing standard amount of ink or large amount of ink. Therefore, the number of image formation on recording media can be estimated, and failure in image formation due to a shortage of ink in the middle of image formation can be inhibited.

Further, an oil circulating path is communicated with the region having a slightly widened gap. The gap of this region is set to be greater than the gap at the thrust dynamic-pressure bearing portion by the value of the depth of dynamic-pressure generating grooves. The region having a widened gap may be provided with rows of grooves for stirring-up lubricating oil towards the center.

Measurement/analysis unit in a Java virtual machine has the function of measuring data when an event of garbage collection occurs, and the function of periodically measuring data. The measurement/analysis unit analyzes the measured data and predicts a danger of a memory shortage, and predicts a danger using an algorithm depending on the type of garbage collection used by the Java virtual machine. An application server is notified of a warning of the predicted danger of a memory shortage by an analysis result notification means by an inter-process communication, or the like. The measurement/analysis unit calculates a memory capacity required to avoid the predicted danger of a memory shortage, and the calculated memory capacity is transmitted to the application server by the analysis result notification means by an inter-process communication, or the like in the same way as the warning.

Conventionally, the developer in the developer supply container is discharged by an air-supply pump and a suction pump which are provided in the main assembly side of the image forming apparatus, and therefore, the developer is compacted by the increase of the internal pressure of the developer supply container resulting from the air-supply. Therefore, the proper suction of the developer from the developer supply container becomes difficult with the result of shortage of the developer amount to be supplied.

A bellow-like pump is provided on the side of the developer supply container, and the pump alternately repeats the suction operation and the discharging operation through the discharge opening by a driving force inputted from the image forming apparatus side. By this, the developer can be sufficiently loosened, thus properly discharging the developer.

A cartridge is set in a printer main unit, and has a remaining toner measurer which measures toner in a toner chamber upon setting of the cartridge. A cartridge memory stores information of a remaining toner amount measured previously. CPU compares the remaining toner amount measured newly with the remaining toner amount measured previously and read from the cartridge memory. If there is an increase in the toner, the cartridge is determined as improper cartridge reloaded with the toner. An alarm signal is generated. Also, printing is inhibited. In another preferred embodiment, shortage information is assigned to the cartridge upon using up the toner. The cartridge, if it has the shortage information, is determined as improper. If a characteristic of the toner is not within a reference range, the cartridge is determined improper. In another preferred embodiment, an upper limit of the number of times of toner reloading is predetermined. The cartridge is determined improper if the reloading time number comes up to the upper limit. The improper cartridge is set in a state in which operation is inhibited. Also, when the cartridge is disassembled, the improper cartridge is inhibited from operating.

The invention provides a remote unmanned aerial vehicle cluster control method and system based on 3G (the 3rd Generation Telecommunication) and GPRS (General Packet Radio Service) cell phone communication and belongs to the technical field of unmanned aerial vehicles. Each unmanned aerial vehicle is provided with an independent unique electronic identification code by integrating a cell phone communication module into a flight control computer board card; as long as the system is started and electrified, the current relevant information of the unmanned aerial vehicle is transmitted to a remote control center; a permission instruction is necessarily applied from a control center for each flight; information such as an airway plan is made uniformly in the control center; and the information is transmitted to an operation terminal of the unmanned aerial vehicle through a cell phone communication module. Consequently the unmanned aerial vehicle cannot fly away without a headquarter control instruction. The state of each unmanned aerial vehicle is fed back to the control center and can be shared with networked data of relevant national supervision departments so as to play roles in unified supervision and scheduling. In addition, the on-site operation personnel do not need professional knowledge such as airway point setup; and the unmanned aerial vehicle can be operated by common people subjected to simple training, so that the problem of staff shortage in unmanned aerial vehicle control is solved.
