Title: 음향 에코 제거기
IPC: H04B3/23
Filed: 1998-04-30
Abstract: 적응 에코-소거 필터의 유효 전달 함수 계수가 주기적으로 시스템 상태 변화에 따라 조정되는 에코 제거기가 개시된다.  유효 계수의 주기적인 조정은, 시스템 파라미터 측정의 전략적이고 신규한 조합에 기초하여 변화되는 보다 자주 조정되는 갱신 계수 및 갱신 게인을 사용하여 실현된다.  연속적이기 보다는 주기적으로 필터링 계수를 갱신하고 갱신 게인의 크기에 대해 소프트하며 퍼지-논리형인 결정을 함으로써, 예시적인 실시예들이 안정성이 훼손되지 않고 시스템 속도 및 적응을 최적화한다.  일반적으로, 비교적 큰 갱신 게인은, 파-엔드 사용자만이 말하고 근단 신호가 비교적 노이즈가 없는 상황에서 적용된다.  그러나, 근단에서의 싱글 토크, 더블 토크, 및 높은 근단 노이즈 상황에서, 적응 필터가 비안정화되지 않거나 근단 스피치 및 노이즈 신호의 왜곡을 유발시키지 않도록 보다 보수적인 방법이 사용된다.  이러한 상황에서, 갱신 게인은, 적응 필터가 일반적인 안정 상태 에코 환경에 일치하도록 수렴하여, 이미 적당하게 적응된 필터의 에러 방해요소가 최소화된다.  비수렴 기간 동안에 높거나 낮은 갱신 게인을 적용하는지의 여부에 대한 결정은, 피크 갱신 계수값 및 기준선 갱신 계수값의 비율을 포함한 시스템 상태 게이지에 일부 의존한다.  시스템 상태 게이지는 그 중에서도 시스템 수렴의 레벨을 가리킨다.  예시적인 실시예에서, 비교적 높은 가변 갱신 게인은 수정된 정규화 최소공배수(NLMS) 알고리즘을 사용함으로써 비수렴된 파-엔드 싱글 토크 상황에 적용된다.  다른 비수렴 상황에서는, 갱신 게인은 시스템 상태 게이지의 정규화 버젼에 기초하여 보다 보수적으로 조정된다.  시스템 불안정성을 생성하지 않도록 주의하면서비교적 큰 갱신 게인을 동적으로 제공함으로써, 예시적인 실시예는 다양한 시스템 환경 및 상태에서 성공적으로 에코을 소거하도록 신속하고 강력하게 적응된다.

Abstract: A sintered material and the tough-coated hard powder (TCHP) to make such a material is comprised of core particles that consist essentially of a first metal compound having the formula M a X b. M is a metal selected from the group consisting of titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, aluminum, boron and silicon while X represents one ormore elements selected from the group consisting of nitrogen, carbon, boron and oxygen. The letters a and b represent numbers greater than zero up to and including four. The core particles are surrounded by an intermediate layer consisting essentially of a second metal compound, different in composition from the first metal compound thereby forming coated particles. The material of the intermediate layer has a higher relative fracture toughness than the material comprising the core particles and is capable of bonding with the metal compound(s) forming the core particles and also being capable of bonding with iron, cobalt or nickel. The coated particles are surrounded by an outer layer of iron, cobalt, nickel, their alloys, their mixtures and their intermetallic compounds. The intimate liaison of multiproperty alloys within the TCHP grains allows the combination of normally conflicting sintered article performance characteristics (e.g., strength and hardness) at levels heretofore unseen in the powder metallurgical art.
