Abstract: A media access control (MAC) address management system, comprises logic configured to generate a MAC address for at least one network device of a computing device based on a MAC address of another network device of the computing device.

Abstract: A paper feeding module including a first shaft, a first ring-shape structure, a paper picking roller and a paper feeding roller is provided. The first shaft has a first stopping block. The first ring-shape structure rotatably covers the first shaft and has a second stopping block and a third stopping block, wherein the first shaft drives the first ring-shape structure to rotate while the second stopping block is pushed by the first stopping block. The paper picking roller rotatably covers the first shaft and is located on the paper feeding path, and has a fourth stopping block, wherein the first ring-shape structure drives the paper picking roller to rotate while the fourth stopping block is pushed by the third stopping block. The paper feeding roller is disposed on the paper feeding path.

Abstract: A paper stopper mechanism for paper-feeding apparatus, which has simplified structure and commonly uses one motor to stop papers. The paper stopper mechanism includes a rotary shaft driven by a drive shaft via a gear assembly, a stopper plate disposed on the rotary shaft, which is movable between a first position and a second position along with the rotation of the rotary shaft, and a resilient member positioned between the rotary shaft and a transmission gear of the gear assembly. There is frictional force between the rotary shaft and the transmission gear, whereby the transmission gear can drive the rotary shaft to rotate. When the stopper plate and the rotary shaft stop at the second position, the transmission gear can still transmit power to a pickup roller to feed a paper into the paper-feeding apparatus without any error.

Abstract: Embodiments of the present disclosure include chemical compositions, structures, anodes, cathodes, electrolytes for solid oxide fuel cells, solid oxide fuel cells, fuel cells, fuel cell membranes, separation membranes, catalytic membranes, sensors, coatings for electrolytes, electrodes, membranes, and catalysts, and the like, are disclosed.

Abstract: A control assembly for an electronic device includes a housing, a control and a support member. The housing defines a chamber and an opening. The control is received in the opening of the housing. The support member is received in the chamber and resists the control.

Abstract: A battery holder (10) is provided. The battery holder (10) includes a body member (11) defining a battery receiving space (113), a latching member (13) fixed to the body member (11) and a battery (12) received in the battery receiving space (113). The latching member (13) includes a latching portion (133). The battery (12) defines a first latching groove (1221). The latching portion (133) latches into the first latching groove (1221).

Abstract: An earpiece fixing structure is configured for fixing an earpiece module and a flexible printed circuit board in a fixing seat of an electronic device. The earpiece fixing structure comprises a cover and a plurality of latching portions bent from the cover. The cover covers the earpiece module and the flexible printed circuit board received in the fixing seat, and the latching portions latch to the fixing seat. Also disclosed is an electronic device using the earpiece fixing structure.

Abstract: A method of tamper-resistant control comprising reading a flag of an electronic device with firmware, the flag indicating a provision enable/disable state of the electronic device and provisioning a management processor of the electronic device to facilitate communications between the management processor and a server in response to reading the flag indicating a provision enable/disable state
