Abstract: A method for removal of mercury from gas, using chemically treated carbons, including the contact of the mercury-containing gas with a chemically treated substrate, wherein the substrate surface has developed metal oxide, carbonyl and halide functionalities.

Abstract: A novel portable electronic device including a first housing portion (106) having a first battery (135) integrally associated with the first housing portion and a second housing portion (104) having a second battery (102) operatively coupled to an external surface of the second housing portion. Also, a method for coupling power to a portable electronic device comprises steps of providing a recessed region in a first housing portion for receiving a first battery and operatively coupling a second battery to an external surface of a second housing portion.

Abstract: A latching mechanism (160) disposed on an accessory (102) for attaching the accessory (102) to a portable device (100) includes a support (164) and a latch (162) disposed about opposite ends (150, 152) that mate with first and second portions (206 and 300, 302) of a retaining device (123) disposed about opposite ends (112, 122) of the portable device (100). The support (164) includes feet (412, 414) having prongs (420) that face a hooked end (404) of the latch (162). The latch (162) includes a spring (502, 510) coupled to the hooked end (404) such that when the latch (162) is extended, the hooked end (404) exerts a force (700) on the first portion (206) of the retaining device (123) drawing the support (164) into abutment with the second portion (300, 302) of the retaining device (123). The exerted force (700), which is in a plane parallel to a front surface (146) of the accessory (102) extending between the ends (150, 152) thereof, maintains the accessory (102) in attachment with the portable device (100).
