Abstract: The invention relates to a system for anti-fall protection of individuals during work on ladders with rungs. The system comprises an anti-fall protection with a first and a second side and a displaceable hinge that can be secured to an individual by means of safety line, harness or the like, and a rail for attachment in an essentially vertical position on or at the ladder. The anti-fall protection and the rail has co-operating locking means that are adapted to be such that the anti-fall protection can slide on the rail when the rail is displaced in one direction and is securely locked onto the rail when the hinge is displaced in another direction. Rail and anti-fall protection are also configured with complementary and asymmetrical engagement means to the effect that the anti-fall protection can be mounted on the rail with only one side upwards, and said first and second sides being mutually displaceable to the effect that the engagement means can be caused to disengage from the rail. Between the first and the second sides, the anti-fall protection also comprises connection means that cooperate with the hinge to the effect that the first and second sides of the anti-fall protection can be shifted out of engagement with the rail only when the hinge is displaced in one direction.

Abstract: Mobile communication devices having multiple speakers and/or microphones to perform a number of audio functions for use with mobile devices are provided. The microphones may be housed within the communication device housing. To compensate for the unwanted signal feedback between the speakers and microphones acoustic echo cancellation may be implemented to determine the proper distance and relative location between the speakers and microphones. Acoustic echo cancellation removes the echo from voice communications to improve the quality of the sound. The removal of the unwanted signals captured by the microphones may be accomplished by characterizing the audio signal paths from the speakers to the microphones (speaker to microphone path distance profile) including the distance and relative location between the speakers and microphones. The optimal distance and relative location between the speakers and microphones is provided to the user to optimize performance.

Abstract: 이 발명은 테이프카세트의 허브 케이스 가이드장치에 관한 것으로서, 양측 허브가 회전자유롭게 설치된 케이스의 저면 양측에는 고정홈이 형성되고, 상기 고정홈에는 허브 케이스의 회전중심 위치를 결정할 수 있도록 고정핀이 끼워맞춤되고, 상기 고정핀을 중심으로 회전하는 허브 케이스 상면을 탄력적으로 누르는 판스프링을 구비함으로써, 허브 케이스의 회전중심이 되는 고정핀의 조립성 및 수직도 관리가 용이하고, 허브 케이스 회전시 허브와의 접촉에 따른 상호간섭을 피할 수 있으므로 회전드럼측으로 주행되는 테이프카세트의 오동작을 미연에 방지할 수 있다.
