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, Kafe, Webinar 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.

초록

An electromagnetic interference (EMI) shield for a handheld cellular phone that is particularly useful for shielding a hearing aid against EMI from the phone's antenna. The device includes a base and a flap laminated with a metallic shielding. The base attaches to the receiver end of the cellular phone and the flap rests over the base when the phone is not in use. In operation, the flap extends away from the base forming an enclosure about the user's ear for shielding the hearing aid from EMI when the phone is in use.

대표
청구항

[ What is claimed is:] [1.] A device for providing an electromagnetic interference (EMI) protected zone comprising:a base for attachment to a hand-held cellular telephone;a flap comprising a metallic shielding laminated material; andmeans for coupling said flap to said base for allowing displacement of said flap between a storage mode when said flap rests over said base, and an operating mode when said flap extends away from said base to form said EMI protected zone about a user's ear.
