  • Publication number: 20070251559
    Abstract: A walking stick includes a shank, a handle, a housing, and a control circuit device. The control circuit device includes a circuit board, a gear unit, a rocker lever, a generating motor, a storage battery, a lighting circuit, a warning circuit, a sounding circuit, and a charging circuit. Thus, the walking stick can provide an illuminating effect, a video warning effect, an audio warning effect and a recharging function. In addition, the user only needs to swivel the rocker lever to drive the generating motor to generate an electric power which is stored in the storage battery unit, so that the walking stick can generate an electric power manually without having to replace any battery, thereby facilitating the user operating the walking stick outdoors.

  • Publication number: 20060146519
    Abstract: A shining device for a manual electric tool includes a light source fixed on a manual electric tool, a control circuit connected electrically to the light source, a control switch connected to the control circuit for turning on and off the light source, an electric double layer capacitor connected to a battery of the electric tool. The light device can be used in a dark place and moved together with the electric tool so as to avoid the undesired conditions of some working areas or corners lack of light. The light source can also be lit to flash on and off, shown as a warning signal. In addition, the electric double layer capacitor can supply the light source with weak electricity by storing the electric volume of basic potential difference of the battery even if the electricity of the battery is used up.
