  • Publication number: 20120161572
    Abstract: Various electric motor systems are provided to minimize irradiation of harmful (or first) electromagnetic waves. More particularly, an electric motor system is provided with one or more counter units which minimize irradiation of such harmful (or first) waves by suppressing such waves to (or toward) their sources and/or by emitting counter (or second) electromagnetic waves capable of canceling a desired portion of the harmful (or first) waves. Such counter units may then be incorporated into various locations for opposing magnetic poles of basic rotor units and/or basic stator units of the system. Various methods are also provided to minimize irradiation of such harmful (or first) waves by suppressing the harmful (or first) waves toward their sources and/or by canceling such harmful (or first) waves with the counter (or second) waves.

  • Publication number: 20110200380
    Abstract: Various multicolor writing tools and methods for applying multiple volatile marking substances one at a time. The tool includes a case member, a cartridge member, a cap member, and an optional actuator member. The case member forms an interior in which is disposed the cartridge member with multiple cartridges each containing one of the marking substances and a tip through which the marking substance is applied. The cap member changes and restores its configuration, while the actuator member changes, the configuration and exposes one of the tips selected by an user out of the interior when the tool is in use, and then restores the configuration and encloses all of the tips inside the interior when not in use. Thus, the tool opens the cap member in response to input force without requiring the user to engage in a separate maneuver to remove the cap member.

  • Publication number: 20110095935
    Abstract: Various electromagnetically-countered systems (EMC systems) are provided to form a target space where an intensity of harmful electromagnetic waves is reduced by a preset extent or below a preset limit. The EMC system includes at least one counter unit which emits counter electromagnetic waves capable of countering the harmful waves by canceling at least a portion of the harmful waves in the target space or by suppressing the harmful waves from propagating into the target space. As the countering is performed by the canceling, the counter waves tend to counter the harmful waves while impeding the purpose of the system in the target space. However, as the countering is done by the suppressing, the counter waves tend to oppose the harmful waves while facilitating the purpose of the system at least outside the target space.
