The radio loads f(2) into the synthesizer (102). After waiting 17 ms (103), the radio makes a first determination (104) whether the synthesizer is locked on f(2). After waiting 17 ms (105), the radio makes a second determination (106) whether the synthesizer is locked on f(2). If the first determination and the second determination are both affirmative (107), the radio determines (120) whether carrier activity exists on f(2). Otherwise, after waiting 17 ms (108), the radio makes a third determination (109) whether the synthesizer is locked on f(2). If the second determination and the third determination are both affirmative (110), the radio determines (120) whether carrier activity exists on f(2). Otherwise, if the third determination is affirmative (111), after waiting 17 ms (112), the radio determines (120) whether carrier activity exists on f(2). Otherwise, if the third determination is negative, the radio postphones (130) determining whether carrier activity exists on f(2).

Inventor: BODO PFEIFFER
IPC: G06F13/00

Abstract: 복수의 유사유닛을 제어하는 방법과 그 회로 장치 및 스위치 소자 
     종래기술 : 예를들어 ATM스위치 소자의 버퍼는 나중에 다른 데이타 싱크에 의해 호출되는 랜덤 데이타를 수신한다. 데이타가 데이타 싱크에 출력된 후에 버퍼의 메모리 위치는 해제, 즉 다시 자유로워진 것으로 표신된다. 
     기술적 문제 : 착오로 인하여 자유로운 것으로 표시되지 않은 메모리 위치는(데이타가 실수로 호출되지 않거나 해제절차가 잘못되었거나에 관계없이)차단 상태를 유지한다. 
     기본 아이디어 : 내용들이 완전히(또는 적어도 매우 유사하게)호출되어질때까지 버퍼에 기억되어 있는 모든 메모리 위치들은 자유로운 것으로 표시된다. 
     해결책 : 데이타와 함께 입력시에 정보가 기억된다. 모든 메모리 위치들은 그 내용물이 기억되어 있는 동안 일정한 간격으로 체크된다. 미리 정해진 시간이 경과할때 그 위치는 자유로운 것으로 표시된다.
Patent KR-960004873-B1 (KR)
Title: Process for the preparation of unsaturated bromides
Inventor: DECAUDIN ROBERT
IPC: C07C21/14
Filed: 1991-07-05
Granted: 1996-04-16
Abstract: Process for the preparation of unsaturated bromides by reaction of hydrobromic acid with unsaturated alcohols, characterised in that the reaction is carried out in the presence of a metal or of a metal salt as catalyst. It is particularly useful for the production of allyl bromide.
Patent KR-940003509-B1 (KR)
Title: Ring control device
Inventor: PARK JONG-SUN
IPC: H04M1/00
Filed: 1991-08-01
Granted: 1994-04-23
Abstract: This device increases the sound volume according to the number of calling signals or the surrounding illumination. The control device includes a tone ringer unit (1) which outputs tone signals, a counter (2) which outputs ripple carry signals, a D/A converter (3) which converts digital counts to analog voltage, a monostable vibrator (4) which resets the counted outputs of counter (2), a multiplexer (5) which connects the mode states, a comparator (6) which compares input voltage with reference voltage, a D flip-flop (7) which outputs the input signal.
