| 摘要 |
The spectacles frame (1) incorporates a receiving apparatus (2) for a signal emitted by a transmitting station (3), in consequence of which it emits an acoustic and/or luminous signal. The apparatus is constituted by a miniaturized electronic unit fed with electric current generated by one or more batteries. It may also be activated by a device which converts kinetic energy into electrical energy. It also incorporates an aerial (2a) for signal reception. Another alternative is for the electronic unit to be activated by photovoltaic cells. The frame comprises a frontal body (4) and two bows (5,6), in which the apparatus and aerial are incorporated. |
