연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A device having an initiator and an integrated planar switch. The initiator has a base, an initiating element that is coupled to the base, a first element pad, which is electrically coupled to a first side of the initiating element, and a second element pad, which is electrically coupled to a second side of the initiating element opposite the first element pad. The integrated planar switch has a source pad and a return pad. The source pad is coupled to the base and is spaced apart from the first element pad by a first gap distance to define a first gap t...

What is claimed is: 1. A device comprising: an initiator and an integrated planar switch, the initiator having a base, an initiating element, a first element pad and a second element pad, the initiating element being coupled to the base, the first element pad being electrically coupled to a first side of the initiating element, the second element pad being electrically coupled to a second side of the initiating element opposite the first element pad, the integrated planar switch having a first switch pad and a second switch pad, the first switch pad being coupled to the base and being spaced apart from the first element pad by a first gap distance to define a first gap therebetween, the second switch pad being coupled to the base and being spaced apart from the second element pad by a second gap distance to define a second gap therebetween; wherein the device is operable in a mode in which electrical enemy is transmitted across said first gap from said first switch pad to said first element pad, through said initiating element to said second element pad, and across said second gap from said second element pad to said second switch pad. 2. The device of claim 1, wherein each of the first and second element pads has an outboard edge that is adjacent a respective side edge of the base. 3. The device of claim 1, wherein the initiator is an exploding foil initiator and the initiating element is a bridge. 4. The device of claim 1, wherein the first gap has a minimum width of about 0.012 inch and the second gap has a minimum width of about 0.006 inch. 5. The device of claim 1, wherein the device is a detonator. 6. A device comprising: an initiator and an integrated planar switch, the initiator having a base, an initiating element, a first element pad and a second element pad, the initiating element being coupled to the base, the first element pad being electrically coupled to a first side of the initiating element, the second element pad being electrically coupled to a second side of the initiating element opposite the first element pad, the integrated planar switch having a first switch pad and a second switch pad, the first switch pad being coupled to the base and being spaced apart from the first element pad by a first gap distance to define a first gap therebetween, the second switch pad being coupled to the base and being spaced apart from the second element pad by a second gap distance to define a second gap therebetween; wherein the first switch pad includes an edge that borders the first gap, a second edge that borders a third gap, the third gap being disposed between the first switch pad and the second element pad, the first gap being associated with a first gap distance, the third gap being associated with a third gap distance, the first gap distance being smaller than the third gap distance. 7. The device of claim 6, wherein the first switch pad is generally triangular in shape. 8. A device comprising: an initiator and an integrated planar switch, the initiator having a base, an initiating element, a first element pad and a second element pad, the initiating element being coupled to the base, the first element pad being electrically coupled to a first side of the initiating element, the second element pad being electrically coupled to a second side of the initiating element opposite the first element pad, the integrated planar switch having a first switch pad and a second switch pad, the first switch pad being coupled to the base and being spaced apart from the first element pad by a first gap distance to define a first gap therebetween, the second switch pad being coupled to the base and being spaced apart from the second element pad by a second gap distance to define a second gap therebetween; wherein the second switch pad includes an edge that borders the second gap, a second edge that borders a third gap, the third gap being disposed between the second switch pad and the first element pad, the second gap being associated with a second gap distance, the third gap being associated with a third gap distance, the second gap distance being smaller than the third gap distance. 9.
