Autonomous radio-controlled clock |
摘要 |
<p>An autonomous radio timepiece comprises a casing and a bracelet attached thereto. The casing includes an operating circuit, while the bracelet carries a flexible antenna. The antenna can be removed from the bracelet in the event that the bracelet is worn and must be discarded. The antenna carries a plug-in type connector at one end which is adapted to make a tight sealing connection with the casing, and is also adapted to electrically connect the antenna with the circuit of the casing. The circuit within the casing includes a receiver which is fixedly tuned as a function of the antenna inductivity of a foil core to the time message transmitter. Also provided is a variable automatic supplemental tuner to compensate for bending of the bracelet while the receiver is actuated. The antenna comprises a foil of an insulting material on which an antenna conductor is printed, along with two shielding conductors extending parallel to the antenna conductor.</p> |
