| 摘要 |
A method, means, apparatus, and system is disclosed, for use with an electrically controllable light-producing activity, or possibly an electrically-controlled sound producing activity. In one embodiment, the light is modulated to affect an imaging function, as a secondary effect, without substantially affecting a primary or main purpose of the light-producing activity. In another embodiment, the light is modulated to affect an imaging function, as a secondary effect, in conjunction with effects on the primary or main purpose of the light-producing activity. The invention is useful, for example, in TIG (Tungsten Inert Gas) welding where the light-producing arc, and possibly some light-producing utility lights, are modulated to improve a computer vision system (such as an auto darkening welding helmet or a headup display for a welding helmet) that helps a person see better. Cybernetic and physiological sensing is disclosed such as EEG, ECG, and the like, in conjunction with wearable computing. |
