Abstract: PURPOSE: A method for transmitting multi resolution audio signals via wireless devices in a radio frequency system wherein audio signals are decomposed into levels of resolution (38). CONSTITUTION: A audio signals is decomposed into levels including a base signal at a base transmission rate and one or more signal details. The base signal represents the quality of the signal. Each signal detail, when added to the base signal, improves the resolution of the signal by increasing the detail and the transmission rate. An audio receiving unit (50) transmits a request for audio transmission to the audio transmitting unit (30). In response to the initial request, the base signal is transmitted to the audio receiving unit. If the base signal is insufficient, the sound quality can be increased incrementally by sending further request to transmit additional signal detail. The additional signal detail is then recombined with the base signal at the audio transmitting unit to provide a higher level of sound quality to the signal. The higher quality audio signal is then transmitted to the audio receiving unit.

The rotational force is changes per propellant angle through a power transfer member(2) connected to the angular velocity converter, and transferred to a centrifugal generator(3). The propellant power is generated in one direction as the rotational velocity per propellant angle of the rotatable weight(32) is changed. The rotatable weight is mounted at the centrifugal generator rotated centering on a central shaft(31) connected to the power transfer member. The propellant power is generated in a specific direction having the maximum rotational velocity of the rotatable weight. Therefore, a mounted equipment is moved in a specific direction.

Abstract: 본 발명은 천연무기질물질로된 담수역의 유독성 조류(규조류, 남조류, 녹조류, 편모조류) 방제제의 제법 및 이의 방제장치에 관한 것이다. 
     종래의 상수원수의 조류를 제거하는 방법으로는 펌프에 의해 물을 흡입하여 Filtering하는 방법, 차광막을 사용하여 빛을 차단하는 방법, 수중 폭기조를 이용하여 물을 대류 시키는 방법, TiO 2 와 빛을 이용한 살균방법 등 여러가지 방법들이 개발되어 잇으나, 경제적 측면 및 기술적 측면에서 실용화가 어려운 실정이다. 
     특히 다목적 댐 또는 식수전용 댐의 물을 상수도사업소에서 급수하여 수도물 생산 공정에서 조류(藻類)를 제거하는 방법은 현재 고분자 응집제를 사용하고 있으며, 부수적인 방법으로 규조토, 활성탄사용, 오존처리공정 등을 거쳐 조류를 제거하여 맑은 물을 공급하기 위해 심혈을 기울이고 있다. 
     남조류(濫藻類), 규조류(珪藻類), 녹조류(綠藻類), 편모조류(鞭毛藻類)는 수질오염이 심한 담수역에 광범위하게 발생 번무하고 있으며, 발생 후는 특히 부영양화가 진행되어 수중에 영양염류의 농도가 높은 수계에서 온도가 높은 여름철에 남조류는 Scum을 형성한다고 알려져 있으며, 이들은 시각적인 면은 물론이고, 불쾌한 맛과 냄새를 유발시키고 있으며, 인체에 피해를 주는 유독성 물질을 생산하고 있으나, 이와 같은 담수역에서는 조류 제거 및 방제방법은 아직까지 전무한 실정이다. 매년 되풀이되는 상수원수 댐의 조류발생 확산을 방제하지 못하고 방치하고 있는 실정이며 이는 상수도 처리공정에서 가장 많은 어려움을 겪고있는 실정이다.

     또한, 항공기(헬리콥터)에 장치된 살포기 몸체(1)의 호퍼(1")에 투입하여 엔진회전수 또는 콤프레셔의 공기압력을 조절하여 적당량이 배출관의 유입구(3')내로 유입되게 한 다음 엔진(2) 및 콤프레셔(2")를 가동시키면 이의 높은 풍압과 풍력에 의해 호퍼(1') 내에 유입된 천연무기물질로된 방제제(6)는 분사구(3")를 통해 수면에 연막처럼 광범위 (반지름200m이상)하게 분사되어 담수면 위에 낙하하게 되고, 이와 같이 낙하된 천연무기물질로된 방제제(6)는 탐수중에 침강될시는 10μm(미크론)이하의 미립자이므로 콜로이드상으로 8∼20시간 존재하며, P(인)과 N(질소) 조류(규조류, 남조류, 녹조류, 편모조류 등)를 이온흡착, 응집 침전과정을 거쳐 담수면 저층에서 유기분해 시키며 조류학산현상 방제에 신속히 대처할 수 있게 한 것이다.
