  • Publication number: 20170019642
    Abstract: A wearable imaging device including a device body, an image lens, a linking strap, a first magnetic member and a second magnetic member is provided. The image lens is disposed on the device body. The linking strap has a first end and a second end, and the first end is connected to the device body. The first magnetic member is disposed at the second end of the linking strap. The second magnetic member is disposed on the device body. The first magnetic member is magnetically attached to the second magnetic member, so that the second end of the linking strap is detachably attached to the device body and thus, a hanging hole is formed.

  • Patent number: 9309127
    Abstract: A reagent is provided for removing mercury (Hg). The reagent contains metal carbonates compound with layers structure. The contents of metals of reagent can be adjusted using this method. The reagent can be manufactured with kilogram grade per batch. The common ions, like Mg, Ca, Mn, Fe, Co, Ni, Cu, Zn, etc., can be contained in the reagent. The manufacture method provides a low-cost way for the Hg sorbent and the content ratio of metal oxides can be higher than 50 wt %. The manufacture is operated at a temperature more than 200° C. and can be integrated with existing technology such as denitration catalysts in industry for removing Hg. In another word, the present invention fabricates a mercury-removing reagent of metal-M/aluminum carbonates (M-Al—CO3), which can be potentially combined with commercially selective catalytic reduction (SCR) catalysts for developing medium-high-temperature mercury-removing reagent with mercury-removing efficiency further enhanced.
