  • Patent number: 11300988
    Abstract: A voltage boosting method, system, and circuit which can be incorporated into a battery or device or can be added as a circuit that interfaces between a battery and a device. Optionally, the voltage boosting system can be added without requiring the battery or the device to be modified. The voltage boosting circuit incorporates a pair of transformers and does not require a step-up transformer, thus enabling the circuit to be constructed in a compact form, optionally within a single integrated circuit package. One or more mechanical or automatic switches can be provided which enable the voltage boosting circuit to be disconnected from the battery and the load until such time as the voltage of the battery or battery bank falls below a predetermined amount, at which time the one or more switches can be activated, thus engaging the voltage boosting circuit.

  • Publication number: 20130172279
    Abstract: A pharmaceutical composition comprises (a) an antibacterial agent in an antibacterially effective amount, illustratively comprising clindamycin or a pharmaceutically acceptable salt or ester thereof; and (b) an antifungal agent in an antifungally effective amount, illustratively comprising butoconazole or a pharmaceutically acceptable salt or ester thereof. The composition is adapted for application in a unit dose amount to a vulvovaginal surface and has at least one nonlipoidal internal phase and at least one lipoidal external phase that is bioadhesive to the vulvovaginal surface. The composition is useful for administration to a vulvovaginal surface to treat a mixed bacterial vaginosis and vulvovaginal candidiasis infection.
