Abstract: A memory array and an operation method of the memory array are provided. The memory array includes first and second ferroelectric memory devices formed along a gate electrode, a channel layer and a ferroelectric layer between the gate electrode and the channel layer. The ferroelectric memory devices include: a common source/drain electrode and two respective source/drain electrodes, separately in contact with a side of the channel layer opposite to the ferroelectric layer, wherein the common source/drain electrode is disposed between the respective source/drain electrodes; and first and second auxiliary gates, capacitively coupled to the channel layer, wherein the first auxiliary gate is located between the common source/drain electrode and one of the respective source/drain electrodes, and the second auxiliary gate is located between the common source/drain electrode and the other respective source/drain electrode.

Abstract: A battery cartridge, a battery carrier module, and a battery charging system are provided. The battery cartridge includes a carrier case and a dismantable assembly. The battery cartridge has an accommodating space for accommodating a rechargeable battery. The accommodating space has a maximum width and a maximum depth, the rechargeable battery has a predetermined width and a predetermined depth. The dismantable assembly is disposed in the accommodating space of the carrier case. The dismantable assembly includes a width adjustment part and a depth adjustment part. The maximum width and the maximum depth of the accommodating space are respectively greater than the predetermined width and the predetermined depth of the rechargeable battery, and one of the width adjustment part and the depth adjustment part is disposed between the carrier case and the rechargeable battery so as to maintain the relative position between the rechargeable battery and the carrier case.

Abstract: A battery exchange system and a battery exchange method are provided. The battery exchange system includes a plurality of battery exchange stations, a central control station and a handheld electronic device. Each battery exchange station includes a battery exchange device. The battery exchange device includes a battery carrier module. The battery carrier module includes a cabinet and at least one battery storage case disposed in the cabinet. The battery storage case has a storage space for accommodating a fully-charged battery. The fully-charged battery provides a second battery-location information and a battery in-stock information through the corresponding battery exchange station.

Abstract: A heat sink has a conducting heat seat, multiple heat pipes and multiple heat dissipating fins. The heat pipes are mounted through the conducting heat seat and each heat pipe has a central portion and two distal portions. The central portion is flat. The distal portions on one side of the conducting heat seat lined zigzag. The flat central portions and zigzag lined distal portions allow more heat pipes to be mounted through the seat per unit area. The heat dissipating fins are separately mounted on the first conducting distal portions of the heat pipes to transfer heat to the atmosphere.

Abstract: A white light LED having a supporting frame; at least one light emitting chip being installed on the supporting frame; a transparent body covering upon the chip; the transparent body being mixed with florescent powders. The florescent powders causes that light emitted from the chip and then passing through the transparent body will present as white light. The chip is a blue-light light emitting chip or an ultraviolet-light light emitting chip and the florescent powders is yellow florescent powders. The supporting frame has two pins. The transparent body is made by at least one of silicide gel, glass, epoxy resin, and epoxy resin with silicide. The transparent body encloses a part of the supporting frame.
