Abstract: A water level detection device includes a case, a detection assembly, and a latching ring secured to the case. The detection assembly includes a warning module, a micro switch, a cable, and a floater. The cable is inserted through the latching ring and divided to a first section connected to the micro switch and a second section connected to the floater. When a water level is in an upper limit or a lower limit, the second section is tight, and an angle is defined between the second section and the first section. When the water level is between the upper and the lower limit, the second section is loose. When the water level is over the upper limit or under the lower limit, the floater pulls the first section via the second section to trigger the micro switch to alarm the warning module.

Abstract: An apparatus and method for managing health data through a user terminal are provided. The method includes inputting a user terminal number for identifying the user terminal, and information of a medical instrument for measuring the health data to a management server interworked with the user terminal, receiving, by a receiver, a security type table mapped onto the user terminal number and comprising a security type code for instructing the health data which the medical instrument has measured to be stored in a first memory without security or in a second memory with security, from the management server, and storing the health data in the first memory or the second memory, which the security type code instructs, through determining the security type code of the security type table when the health data is received from the medical instrument.

Abstract: A method of displaying an image by using an image included in a content, and an electronic device using the same are provided. The method includes acquiring an image included in a content, dividing the acquired image into a plurality of regions, acquiring color information related to the plurality of divided regions, and generating a color palette based on the acquired color information. The electronic device provides an image acquirer that is configured to acquire an image included in content; a regions setter configured to divide into a plurality of regions the image acquired by the image acquirer; a color extractor configured to extract color information related to the plurality of divided regions; and a color palette generator configured to generate a color palette based on the color information acquired by the color extractor, wherein the color palette is used to determine a color of the image displayed on the electronic device.

Abstract: A method for providing position information and identifying positions of others, using an electronic apparatus, includes detecting first position information regarding a current position of the electronic apparatus, transmitting a position inquiry request and information regarding a predetermined time period to an external apparatus, receiving second position information regarding a position of the external apparatus from the external apparatus for the predetermined time period, and displaying positions of the electronic apparatus and the external apparatus on a screen using the first position information and the second position information.

Abstract: A content providing method of an electronic apparatus communicably connected with an external apparatus is provided. The method includes receiving a command for transferring content to the external apparatus; checking whether the content includes information indicating that the content is transferable to the external apparatus, the information being set by determining, based on a meta data included in the content, whether a predetermined condition is satisfied; and transferring the content, based on the checked information, to the external apparatus.

Abstract: The present invention relates to a subscriber station security-related parameter negotiation method in a wireless portable Internet system. The subscriber station security-related parameter negotiation method includes security-related parameters in transmitting/receiving basic capability negotiation request messages and basic capability negotiation response messages such that the subscriber station and the base station negotiate the subscriber station security-related parameters. The security-related parameters include an authorization policy support subfield used to negotiate an authorization policy between the subscriber station and the base station, and message authentication code mode subfields used to negotiate a message authentication code mode.

Abstract: A control device which controls the power of a plurality of apparatuses in a home network, and a method thereof are provided. The control device includes an input unit which receives a power off command, and a control unit which concurrently turns off apparatuses which are currently turned on among the plurality of apparatuses in response to the power off command received by the input unit. Therefore, it is possible for a user to concurrently turn off currently running apparatuses so user convenience can increase.
