The present invention relates to a data processing method and apparatus. The invention provides an electronic device including: a communication module; a first location calculating module; a second location calculating module; and a first processor electrically connected to at least one of the first location calculating module and/or the second location calculating module. The first processor may be configured to: identify property information of at least one application that is driven by the first processor and requests location information; determine a location accuracy level on the basis of the identified property information of the at least one application; and select one of the first location calculating module and/or the second location calculating module in order to calculate the location of the electronic device by using a signal obtained through the communication module, according to the determined location accuracy level.

Method for calculating location information and electronic device therefor

Various embodiments provide an electronic device and a method therefor, the electronic device comprising: at least one memory; a communication interface; one or more sensors; a location module; and at least one processor functionally connected to the at least one memory, the communication interface, the one or more sensors, and the location module, wherein the at least one processor is configured to acquire sensing data from at least one sensor among the one or more sensors, estimate a vehicle on-boarding state on the basis of the sensing data, and recognize, on the basis of the estimated vehicle on-boarding state, a vehicle on-boarding state by using the communication interface or the location module. Other embodiments are also possible.

Vehicle on-boarding recognition method and electronic device implementing same

An electronic device and method are disclosed herein. The electronic device includes a communication module, a memory and at least one processor, which implements the method, including responsive to detecting a request to update additional data corresponding to detecting a present location, transmitting a request to update the additional data to at least one external electronic device in communicable range of the communication module, receiving the additional data in response to the transmitted request via the first module of the communication module, detecting a validity of the received additional data, and detecting the present location via the second module of the communication module based at least partially on the additional data if the additional data is detected to be available.

Electronic device and method for acquiring additional data for location information acquisition

Provided is a system and method for transmitting a satellite state to a satellite receiver to determine use or non-use of a satellite signal in positioning estimation. A satellite navigation system includes at least one satellite, a satellite control center for controlling the at least one satellite, and a server. The server transmits satellite state information about the at least one satellite identified through the satellite control center to the satellite receiver. The satellite receiver restricts the use of the satellite signal for positioning estimation when the satellite state is identified as erroneous.

Satellite receiver and system employing server for identifying satellite state

A developing unit includes a developing unit body having a toner inlet and a developing roller mounted in the developing unit body. A toner feeding unit for feeding is provided to feed the toner from the toner inlet to the developing roller. A doctor blade is integrally formed with the developing unit body for controlling the thickness of the toner supplied to the developing roller.

Developing unit and an image forming apparatus

A developing device has a sealing unit that seals a gap between an inner wall of a housing that stores developer and a blade that controls a thickness of developer attached on a developing roller. The sealing unit of the developing device includes a first sealing member inserted into a gap between the inner wall of the housing and an end portion of the blade, a second sealing member placed on the blade to contact the first sealing member, and a pressing member that presses the first and second sealing members so as to prevent gaps between the first and second sealing members. Therefore, the gap between the blade and the inner wall of the housing can be blocked efficiently without damaging the developing roller, and a stable and efficient developing process can be performed.

Developing device having improved sealing structure

A toner cartridge horizontally installed in an electrophotographic printer having a photoreceptor drum where an electrostatic latent image is formed by charging and exposure, and contributing to toner supply and development by being fixedly coupled to in the electrophotographic printer. The toner cartridge includes a housing filled with toner of a predetermined color, a development roller rotatably installed on the housing to face the photoreceptor drum and to supply the toner to the photoreceptor drum to develop an image by a difference in electrical potential, a supply roller rotatably installed in the housing in contact with the development roller and to control the toner to adhere to the development roller, and a guide member coupled to the housing to be disposed under the supply roller and to guide supply of the toner. When a diameter of the development roller is D, the diameter Dsatisfies an inequality that 10.4&#x2266;D&#x2266;22.1 mm.

Toner cartridge and electrophotographic printer employing the same

A toner cartridge and an electrophotographic image forming apparatus using the same are provided. The toner cartridge includes: a toner bottle air-tightly storing a toner; a first shutter sliding in a longitudinal direction of the toner bottle; and a second shutter sliding in a circumferential direction of the toner bottle to open and close a toner outlet.

Toner cartridge having sliding shutters and electrophotographic image forming apparatus

An ink cartridge and a wet-type electrophotographic image forming apparatus having the ink cartridge, wherein the ink cartridge is detachably mounted with respect to an image forming apparatus body and supplies a developing unit with ink. The ink cartridge includes a housing including an inflow inlet into which the ink flows, and an inflow inlet opening and closing unit for operating together with the image forming apparatus body such that when the housing is mounted in the image forming apparatus body the inflow inlet is opened, and when the housing is removed from the image forming apparatus body the inflow inlet is closed. The inflow inlet opening and closing unit includes a moving member installed in the housing so as to move in first and second directions, at least one expanding tube bag installed in the inflow inlet for expanding and/or shrinking, depending on an inflow amount of liquid, to open and/or close the inflow inlet, and a liquid feeding unit for selectively feeding the liquid to and withdrawing the liquid from the at least one expanding tube bag depending on a movement direction of the moving member.

Ink cartridge and wet-type electrophotographic image forming apparatus having the same

A fusing device of an electrophotographic image forming apparatus. The fusing device includes a fusing roller that is heated to be a predetermined temperature, and a pressing roller that presses a sheet of paper passing between the fusing roller and the pressing roller toward the fusing roller. In addition, the fusing roller includes a cylindrical roller having a predetermined diameter, a heater positioned inside the cylindrical roller to heat the cylindrical roller, a rubber member that is formed on a center portion of an outer circumference on the cylindrical roller, and heat resistance portion that is formed on both end portions of the cylindrical roller.
