Abstract:
A locking enclosure includes a base, a cover mounted on the base, and two locking members assembled on the cover. A plurality of supporting recesses and two supporting portions are defined in the base. A plurality of barbs are formed on the cover to match with the supporting recesses, and two elastic arms are assembled on the cover to engage with the supporting portions, whereby the cover is restricted to move relative to the base, and is secured on the base. The locking members each comprise a resisting portion abutting a corresponding elastic arm. The resisting portion can be operated to make the elastic arm disengage from the supporting portion, to remove the cover from the base.
Abstract:
A self-learning method for keyword based human machine interaction is disclosed. At least one of a plurality of keywords predetermined in a database is selected and a priority score of the selected keyword is updated and a weighted factor is generated for the selected keyword. A weighted score and the weighted factor of the selected keyword are transmitted to the keywords related to the selected keyword. The selected keyword is pushed to a keyword buffer and linkage strengths between the keywords in the keyword buffer are strengthened. When a keyword has been stored in the keyword buffer for over a predetermined reset time period, a reset operation is performed to remove the keyword from the keyword buffer.

Abstract:
A computer enclosure includes a front panel, a shielding member, and a linkage assembly. The front panel defines an opening and a pair of sliding slots beside the opening. Each of the sliding slots has a stop portion and a sliding portion. The shielding member includes a pair of sliding posts respectively received in the stop portions of the sliding slots. The linkage assembly is capable of pushing the shielding member to urge the sliding posts sliding from the stop portions to the sliding portions of the sliding slots. The shielding member is capable of covering the opening when the sliding posts are received in the stop portions of the sliding slots and capable of sliding along the sliding portions to expose the opening.
Abstract:
A graphene-based field effect transistor includes source and drain electrodes that are self-aligned to a gate electrode. A stack of a seed layer and a dielectric metal oxide layer is deposited over a patterned graphene layer. A conductive material stack of a first metal portion and a second metal portion is formed above the dielectric metal oxide layer. The first metal portion is laterally etched employing the second metal portion, and exposed portions of the dielectric metal oxide layer are removed to form a gate structure in which the second metal portion overhangs the first metal portion. The seed layer is removed and the overhang is employed to shadow proximal regions around the gate structure during a directional deposition process to form source and drain electrodes that are self-aligned and minimally laterally spaced from edges of the gate electrode.
