20130068678 | WATER SOFTENER HAVING TIMER CONTROL VALVE - A water pressure regenerated type water softener including: a timer control valve having a valve control unit rotated by a timer spring and into which raw water is supplied; a plurality of conduits into which the raw water selectively flows under the control of the timer control valve; a regeneration tank communicating with a regeneration tank inlet conduit of the conduits; and a resin tank unit receiving regeneration water flowing from the regeneration tank and containing an ion exchange resin therein. The water softener can be operated in one of stop mode, soft water mode, raw water mode and regeneration mode under the control of the valve control unit. When regeneration mode is selected, the valve control unit rotates to stop mode by the timer spring after a preset amount of time has elapsed. | 03-21-2013 |

20130186695 | METHOD AND SYSTEM FOR ESTIMATING FOOD COMMODITY INTAKE - Disclosed are a method and a system for estimating food commodity intakes. The method includes (a) obtaining a food intake of a food searched as a subject to be estimated for food commodity intake based on food intake database, (b) obtaining a material mix ratio of the food searched based on the material mix ratio database and estimating a material mix ratio intake using the food intake, (c) detecting whether or not the material contained in the material mix ratio intake estimation results is a food commodity, (d) accumulating a weight data of the material that is detected to be a food commodity among the materials obtained from the material mix ratio intake estimation results, (e) repeatedly performing operations (b) to (d) on materials that are not food commodities, until all of the materials contained in the material mix ratio intake estimation results become food commodities, and (f) summing the accumulated weight data of each food commodity to estimate a food commodity intake of the food, when all of the materials contained in the material mix ratio intake estimation results are food commodities. According to the present invention, more accurate food intake data can be conveniently estimated by converting all ingredients of mixed foods into food commodities. | 07-25-2013 |
