The mobile privacy protection system includes: an electronic tag to store predetermined tag information; a proxy device to adjust a privacy level of the electronic tag; and a home server to create new tag information in response to a request from the proxy device wherein the new tag information is used to adjust the privacy level.
Abstract:
Disclosed are a vanadia-titania aerogel catalyst having high specific surface area and porosity, a method of preparing the same and a method of completely oxidatively-decomposing a chlorinated aromatic compound using the catalyst under air condition. The vanadia-titania aerogel catalyst of the invention is an aerogel form having many porosities and a high specific surface area obtained by performing a supercritical drying of vanadia-titania wet gel, which is prepared by a sol-gel method, with carbon dioxide and then firing the dried vanadia-titania, with a micro porosity structure being maintained, consists of vanadia and titania wherein a content of the vanadia is 1˜15 wt % of an overall catalyst weight. In addition, according to the invention, the vanadia-titania aerogel catalyst may further comprise a manganese oxide of 1-5 wt % or a sulfur component of 0.0001-1 wt %. Since the vanadia-titania aerogle catalyst of the invention has the very high conversion rate and selectivity for the complete oxidation reaction of the chlorinated aromatic compound and is very thermally stable, it can be usefully used in the oxidation reaction having a high heating value capable of generating local heat spots.
Abstract:
A method of controlling storage of a data broadcast application and broadcast receiver processing the same are disclosed. A method of controlling a data broadcast application includes receiving an application of data broadcasting, deciding whether a memory of a broadcast receiver is in a status capable of storing the received application using at least one of information for an overall size of the memory of the broadcast receiver and information for an empty size of the memory of the broadcast receiver, and if the memory of a broadcast receiver is in the status capable of storing the received application, storing the received application in the memory of the broadcast receiver.
Abstract:
A method for managing a user's preference option in a broadcast receiver receiving data broadcasting, a class/interface structure for controlling the same, and a broadcasting receiver for controlling the class/interface receiver can solve a problem encountered when a data broadcast-associated application partially overlaps with a Native application. A method comprising the steps of: receiving a request for setting a function, wherein the function is supported by at least one of a data broadcast-associated application and an application native to a broadcast receiver; accessing setting authority information in response to the request; and storing data associated with the function based on the setting authority information.
Abstract:
A dust collection unit for a vacuum cleaner includes a first dust collection part for filtering foreign objects in air, a second dust collection part for filtering foreign objects in the air that has passed through the first dust collection part, and a dust collection container having first and second dust collection chambers that correspond to the first and second dust collection parts, respectively. The first and second dust collection chambers store the foreign objects filtered by the respectively first and second dust collection parts in a state where parts of the respective first and second dust collection parts are received in the respective first and second dust collection chambers and the first and second dust collection chambers are provided in a line.
