Abstract: An electrical connector for mounting on an external circuit board includes: an insulating body having an upper receiving space and a lower receiving space; a terminal module assembled on the insulating body and including plural pin terminals, each pin terminal having a pin for mounting on the external circuit board, wherein the terminal module is capable of being modified to support 1G or 2.5G or 5G or 10G or 25G or 40G signal transmission while keeping arrangement pattern of the pins unchanged in order to be mounted on the same external circuit board.

Abstract: Various solutions for tiered channel information feedback with respect to user equipment and network apparatus in mobile communications are described. An apparatus may determine a first tier channel state information (CSI) based on a first reference signal resource measurement. The apparatus may report the first tier CSI to a network node. The apparatus may determine a second tier CSI based on the first tier CSI and based on a second reference signal resource measurement. The apparatus may report the second tier CSI to the network node. The second tier CSI may be different from the first tier CSI.

Abstract: This invention relates to a muffler having a purifying system for separating solid contents and eliminating poisonous gases such as carbon monoxide by means of an electrolysis apparatus which continuously provides oxygen separated from water to react with the carbon monoxide into carbon dioxide.

Abstract: An electric bicycle which includes an electric power driving mechanism in combination with a manual pedal driving system. The electric bicycle may be actuated by manual pedalling of the user, or through electrical power actuation or a combination of electrical power and manual operation. The power driving system includes a motor coupled to reduction gears for driving a set of bevel gears. The bevel gears are coupled to a shaft member having secured thereto a transmission gear to engage with a sprocket wheel to displace a standard chain member. The motor is supplied with DC electricity by a battery which may either be charged by solar cells or alternating current passing through a rectifier supplied by an external power system. Still further, the electric bicycle may have its speed controlled with a user's hand actuated speed controller mechanism.

Abstract: An improved laundry drier which includes an outer case as well as an inner case and a tub which is rotationally driven. There is provided a heating housing having heating elements contained therein. A blower is located beneath the heating elements in the heating housing. A first electromagnetic valve is located in a passage of a suction duct. A branch duct is formed into the passage and is in fluid communication with a suction end of the blower. A second electromagnetic valve is formed in the branch duct to control fluid communication between the passage of the suction duct and a spraying duct. There is provided a vacuum apparatus disposed therein. Hot air may be circulated through the spraying duct and finally through the blower and the heating elements in the heating housing during a drying process.
