In order to turn on the SCR gate, trigger signal source have to provide appropriate gate current and voltage under the gate rating based on the characteristic of SCR, the nature of load and power. It will be essential design factors such as trigger source impedance, trigger signal occurring, signal time width and turn off conditions. Also minimum gate trigger current is changed with the deterioration of SCR. SCR, which is needed large gate trigger current absolutely, is very important for SCR characteristic test because it causes unstable output in the misfile or makes a trouble to pulse trigger circuits. This paper shows scheme to test the performance of SCR with the precision analyzing mechanism and the changing trend of minimum gate current under the trigger conditions.

The LPR system's trigger sensor makes problem occasionally due to the heave weight of vehicle or the obsolescence equipment. If we replace the hardware sensor to the deep-learning based software sensor in order to generate the trigger signal, LPR system maintenance would be a lot easier. In this paper we proposed the deep-learning sliding window based object detection and tracking algorithm for the LPR system's trigger signal generation. The gate passing vehicle's license plate recognition results are combined into the normal tracking algorithm to catch the position of the vehicle on the trigger line. The experimental results show that the deep learning sliding window based trigger signal generating performance was 100% for the gate passing vehicles including the 5.5% trigger signal position errors due to the minimum bounding box location errors in the vehicle detection process.

위치기반서비스(LBS: Location-Based Services)의 이용자가 급증함으로써 최근 위치 트리거(Location Trigger) 서비스에 대한 다양한 응용분야가 등장하고 있다. 위치 트리거는 사용자의 이동 위치를 감지하여 특정한 지역에 진입, 존재, 이탈할 경우 사용자에게 단문문자서비스(SMS), 전자메일 등을 통하여 알리거나 또는 사용자에 의해 미리 정의된 특정한 서비스를 제공하는 기술이다 기존에 이러한 위치 트리거 기술은 위치 제공 서버에 주기적으로 위치정보를 요청하여 처리해 왔으나 LBS 서비스 가입자가 증가할수록 서버 및 통신 부하로 인하여 시스템의 성능 저하를 초래하게 된다. 이에 본 논문에서는 위치 트리거를 처리함에 있어서 이동통신망의 위치서버의 부하를 줄이고 모바일 단말기에 임베디드 된 GPS 디바이스의 전력 소모량을 최소화하는 멀티레벨 위치 트리거 방법에 대하여 연구하였다. 실제 본 논문에서 제시하는 방법을 설계하고 테스트베드를 구축하여 성능을 평가함으로써 위치 트리거 기술의 성능 향상에 기여하였다.

Objectives This study was aimed at comparing clinical effectiveness among trigger point treatment, Self-exercise treatment, trigger point - self-exercise cooperative treatment for neck pain caused by traffic accidents. Methods 63 patients with neck pain by traffic accidents were divided into 3 groups. Different types of treatments were carried out for each groups ; group A with trigger point, group B with self-exercise, group C with trigger point and self-exercise cooperative treatment. 3 groups were also treated with general acupuncture and herb-medicine treatment. Pain threshold, visual analogue scale (VAS), and neck disability index (NDI) were checked on a daily basis. SPSS ver. 18.0 for Windows was used for analysis of data. The effectiveness of treatment of each groups were verified by using paired test and one-way repeated-measures ANOVA test, and the comparison of VAS, NDI and pain threshold were demonstrated by independent samples t-test. Results 3 groups all showed significant difference in pain threshold, VAS and NDI after 8 days later. Group C showed more improvement in pain threshold, VAS and NDI than shown in group A and B. In the first period (from pre-treatment to 4th day treatment) group C showed significant difference in NDI and pain threshold but not in VAS as compared to group A and B. In the second period (from 4th treatment to 8th day treatment), Group C showed significant difference in pain threshold, VAS and NDI as compared to group A and B. Conclusions Trigger point - self-exercise cooperative treatment is proved to be more helpful to improve the unstability and reduce neck pain than trigger point treatment or self-exercise treatment only, therefore eventually leading to better satisfaction for patients with neck pain.

Myofascial pain syndrome is one of the major cause of chronic pain and trigger point injection, stretching, spray and electrical therapy are often used in clinical situation for treatment of myofascial pain syndrome. Myofascial pain syndrome is characterzied by the existence of a hypersensitive region, called the trigger point in a muscle or in the connective tissue, together with palpable noble, stiffness, limitation of motion and referred pain when trigger point is stimulated. Physiologically, they represent a self-sustaining vicious cycle of pain-spasm-pain. The purpose of this study is to illustrate mechanisms of pain by stimulation of acupuncture and trigger point, to introduce clinic application of orient and western stimulative point (acupuncture, trigger point)for treatment of MPS(myofascial pain syndrome), to make physiotherapist use both stimulative points for treatment of MPS.

The triggered vacuum switch (TVS) discharges high current through two processes. In the first process, an igniting plasma is generated at a trigger system, and the next process that a main discharge is taken place sequentially at a six-gap rod electrode within a few microsecond. In general, a triggered voltage producing the igniting plasma is increased. However, after several hundred shots, it goes down and stable, in our experiment the trigger voltage is about 5 kV after 250 shots. This triggered characteristics comes from the ceramic insulator which is covered by an electrode material, therefore we have focused on the first igniting plasma process. The igniting plasma has been generated at the surface of a ceramic insulator under a strong electric field. The electric field can be increased through modifying geometries of trigger components which compose of a trigger pin, a ceramic insulator and an enclosed holder. We fabricated not only two types of trigger pin which are a plane head and an umbrella head type, but two different holders which are a concave and a convex type. In this paper the result that the dependency of geometries for these four combined types is included, but the study of the ceramic insulator is not. The research of the ceramic insulator will be announced in the other paper.

Energy absorption capabilities and failure modes of circular tubes made of glass/epoxy with two trigger mechanisms were evaluated. Three types of glass/epoxy tubes were fabricated using a hand lay-up method with unidirectional and woven fabric prepregs tapes, and a filament winding method. The one end of the fabricated tubes was machined for the bevel trigger and tulip trigger. Then, crush tests were conducted at 10 mm/min loading speed, wherein the glass/epoxy tubes were crushed by a brittle fracturing mode combined with fragmentation and lamina-splaying modes. The UD glass/epoxy tubes with a bevel trigger and the filament winded tubes with a tulip trigger showed the maximum and minimum specific energy absorptions, respectively, with a difference of 9.3%. The tube with a tulip trigger exhibited a maximum reduction of 5.7% in the initial peak load; the tube with a bevel trigger showed a maximum increase of 2.9% in the specific energy absorption.
