Abstract: A panel attachable to a backpack body. The panel having at least one through-hole formed therein to allow air to flow into a gap defined between the panel and the backpack body. An air-moving device is mountable to the panel, with an outer portion of the air-moving device extending forwardly from the panel and an inner portion of the air-moving device positioned in the gap. The air-moving device causes air to flow into the gap through the at least one through-hole and into one or more inlets of the inner portion. The air-moving device causes air to flow out one or more outlets of the outer portion.

Abstract: A platform for supporting a conveyor belt of a treadmill includes a wooden plate, a reinforcement plate above the wooden plate, and a shock-absorbing plate sandwiched between the wooden plate and the reinforcement plate. The shock-absorbing plate has a surface facing the wooden plate base, and a plurality of cushions protruding from the surface and stopping against the wooden plate for providing good elastic support force and cushion effect.

Abstract: A hardness adjustable platform for supporting a conveyor belt of a treadmill includes a platform body having internal spaces, and a plurality of elastic fillers moveably and respectively disposed in the internal spaces of the platform body for providing a cushion effect. The fillers are moveable relative to the platform body by an external force and divide the platform body into first and second regions having different hardness. As a result, the runner who uses the treadmill equipped with the aforesaid platform may adjust the positions of the fillers according to his/her physical condition and running speed to change the hardness distribution of the platform so as to enhance his/her running efficiency and reduce the risk of exercise injury.

Abstract: An exemplary particle removing apparatus includes a main body (10) having a chamber (11); a hollow roller (12) being capable of rotating in the chamber, the roller includes an air inlet (123) and a rear portion (124) opposite to the air inlet; a first motor (14) for driving the roller to rotate about a rotational axis thereof; an agitator (13) located in the roller, the agitator being capable of rotating in the roller, and spanning at least most of a distance from the air inlet to the rear portion; and an air feeding unit (20) connecting with the chamber for introducing air into the roller via the air inlet.

Abstract: A system (20) for conveying semifinished products during the manufacturing of liquid crystal displays, includes a first processing station (21); a second processing station (22) proximate to the first processing station; a shortcut conveyor interconnecting the first processing station and the second processing station; a stocking conveyor interconnecting the first processing station and the second processing station, a conveyance route of the stocking conveyor being shortcut by the shortcut conveyor; a data reader (27) for judging if a to-be-processed semifinished product coming from the first processing station is instructed to be conveyed to the stocking conveyor; a sensor (29) for judging if the shortcut conveyor is fully loaded; and a controller for controlling the shortcut conveyor and the stocking conveyor to convey the semifinished product to the second processing station according to judging results of the date reader and the sensor.

Abstract: An integrated circuit (IC) low noise amplifier includes an on-chip balun and an on-chip differential amplifier. The on-chip balun is operably coupled to convert a single-ended signal into a differential signal. The on-chip differential amplifier is operably coupled to amplify the differential signal.
