  • Patent number: 11313552
    Abstract: A protective device and a candle wick burning lamp assembly are provided, wherein the candle wick burning lamp includes a container and a candle wick structure. The candle wick structure includes a candle wick body and a support base fixed with one end of the candle wick body. The support base is placed at a bottom of the container. The bottom of the container is in a circular structure. The protective device includes a central portion and a branch portion. The branch portion is connected to the central portion. A length of the branch portion is 0.7 to 1 time a radius of the circular structure. At least two branch portions are arranged. At least one of the at least two branch portions and/or the central portion are provided with a through hole. The through hole allows the candle wick body to pass through.

  • Publication number: 20110156719
    Abstract: An electrical insulation test apparatus includes a cap having an indentation, and a conductive cushion arranged in the indentation. The conductive cushion has a receiving space sized to meet a tested photovoltaic panel. Since the conductive cushion is deformable, the conductive cushion will deform upon the size of the tested photovoltaic panel for completely contacting with peripheral surfaces of the tested photovoltaic panel when the tested photovoltaic panel is in the receiving space.

  • Patent number: 6226369
    Abstract: A telephone device 100, integrated with a telephone or as a telephone add-on device, improves receipt and processing of network information such as Caller ID from conventional telephone networks. A comparator 103 decodes incoming Frequency Shifted Keying (FSK) signals by transforming transform the FSK signal into a square wave signal with corresponding periodic pulse widths. The transformed signal is sent to a microcontroller 105. The microcontroller is preprogrammed to further decode the transformed signal to obtain digital data representative of Caller ID information. Multiple devices connected to the same telephone line 410 may receive off-hook Caller ID simultaneously by selective disablement of an acknowledgment tone transmission through use of a switch 440. Configurable function keys 471 on a user interface 430 controls other network services, such as voice mail, regardless of different command code formats utilized by various network service providers.
