Abstract:
Provided are a method and apparatus for measuring the position of a communication terminal based on position coordinates of access points and GPS information on the communication terminal. The method comprises: a storing step of storing position coordinates of a plurality of access points in a storage unit; a receiving step of receiving GPS information on the communication terminal from the communication terminal and extracting position coordinates from the storage unit; a calculating step of calculating the position of the communication terminal using the extracted position coordinates; and a correcting step of correcting the calculated position based on the GPS information so as to obtain final position coordinates of the communication terminal.
Abstract:
Disclosed is a multifunctional hot-and-cold-water purifier which has: a primary function which provides users with 3 types of water, hot or cold water, purified water, and soft water; a second function which sterilizes a purified water tank and a cold water tank at a high temperature; a third function which disinfects a user's cup near a first spout discharging hot and cold water using ultraviolet rays; a fourth function which attaches/detaches a second spout discharging soft water and purified water to/from the exterior of the water purifier; and a fifth function which easily ejects a filter in the water purifier through rotation of the filter. Accordingly, since users can use hot and cold water for drinking, purified water for cooking, and soft water for washing hands respectively through the first function, the users can choose water suitable for each purpose. In addition, due to the second function, the users have no need for cleaning the inside of the purifier because they can manage the purifier sanitarily. Furthermore, through the third function, the users can disinfect their own cups easily and conveniently. Due to the fourth function, the users can wash their hands conveniently and fill a large volume container with water for cooking. Also, the fifth function enables all the users to replace the filter easily, so the highest quality of water can be maintained.
Abstract:
The present invention discloses a ultra slim type acoustic transducer which is reduced in thickness, wherein a magnetic closed circuit is constituted for acoustic transduction. The ultra slim type acoustic transducer includes a first magnet which is a vertical magnet (110), and a second magnet which is a horizontal magnet (120), and further includes a central yoke (130) coupled to a lower portion of the first magnet, and an outer yoke (140) coupled to a side surface of the second magnet (120) and also coupled to the central yoke (130), for defining an air gap with the first magnet. A part of a coil portion (150) is inserted into the air gap. The ultra slim type acoustic transducer includes a diaphragm (160) with the coil portion (150) mounted thereon, a protector (200) for protecting the diaphragm (160), and a frame (100) for supporting at least the outer yoke (140) and the protector (200).

Abstract:
Disclosed is a water softener, which is operable in a soft water mode in which cold/hot raw water is changed into cold/hot soft water using an ion exchange resin, a running water mode in which cold/hot running water as the cold/hot raw water is discharged, a regeneration mode in which regenerated water is generated by a regeneration material and regeneration waste water generated in regeneration of the ion exchange resin is discharged, and a control mode in which supply of cold/hot raw water is controlled. The water softener comprises: a tank part comprising first and second soft water tanks filled with the ion exchange resin and a regeneration tank connected to the first and second soft water tanks and filled with the regeneration material; and a switch valve part comprising a first valve assembly connected to the first and second soft water tanks and the regeneration tank, first and second raw water supply pipelines to which the cold/hot raw water is supplied being connected to the first valve assembly, and a second valve assembly connected to the first and second soft water tanks and the first valve assembly, a discharge pipeline from which the cold/hot soft water and the cold/hot running water are discharged and a regeneration waste water pipeline from which the regeneration waste water is discharged being connected to the second valve assembly. The water softener has four special modes in addition to the above four basic modes. With this configuration, users can use and manage the water softener at their most convenience.
