Abstract:
A housing (12) for use in a portable electronic device (10) includes an outer visible surface (14). The outer visible surface (14) is composed of an appearance changing substance responsive to an environmental stimulus.
Abstract:
Wireless communication devices (102, 104, 106, 108, 110) include multi-state visual indicating devices (114, 116, 118, 120, 122, 126, 128) that are operable to alert users that wireless communication links or connections have been established between two or more devices. Upon establishing a connection, the wireless devices share indicia activation information (e.g., color or timing sequence information) and the multi-state visual indicating devices in the devices operate according to the indicia activation information to apprise users that the connection has been established. Activatable indicia (216, 214, 216, 218) that are preferably integral with the wireless device housings inform the device users as to the state of communication.
Abstract:
A method of and fuel cell system for limiting an amount of a fuel crossing over a membrane in a fuel cell, the method including determining an appropriate molecular ratio of the fuel and water for a fuel-water mixture 503; and controlling an amount of the fuel-water mixture that is available to an anode side of the membrane 507 in the fuel cell according to an amount of the fuel that will be electro-oxidized by the fuel cell. The fuel cell system includes a fuel cell membrane 103 having an anode layer 107, a cathode layer 109, and an electrolyte layer 111 where the cathode layer is exposed to an oxygen source, and a fuel delivery system 105 including a fuel chamber 119 disposed around and proximate to the anode layer at a side opposite to the electrolyte layer, the fuel delivery system implementing the method above.
Abstract:
A device housing (20) for a portable electronic device (10) includes an outer visible surface (30). At least one portion (35) of the outer visible surface (30) is composed of one or more optical fibers (40). The one or more optical fibers (40) are illuminated using a light source coupled to at least one end of the one or more optical fibers (40) to provide decorative characteristics and operational functions.
