  • Patent number: 12243762
    Abstract: A door locking mechanism and semiconductor container using the same include door panel, cover, and locking module. The door panel has a first stop structure. The cover and the door panel define an accommodating space for receiving the locking module. The locking module includes rotating member, holding member, and elastic member. The elastic member is disposed on the holding member and has a second stop structure near the first stop structure. The elastic member is disposed between the holding and the rotating member. The elastic member is compressed when a force is applied to the holding member, and the second stop structure detaches from a limitation state with the first stop structure for allowing a rotating operation of the rotating member. The elastic member elastically restores when the force is removed, and the second stop structure returns to the limitation state for limiting the rotating operation.

  • Publication number: 20240371951
    Abstract: Various embodiments of the present disclosure are directed towards a two-dimensional carrier gas (2DCG) semiconductor device comprising an ohmic source/drain electrode with a plurality of protrusions separated by gaps and protruding from a bottom surface of the ohmic source/drain electrode. The ohmic source/drain electrode overlies a semiconductor film, and the protrusions extend from the bottom surface into the semiconductor film. Further, the ohmic source/drain electrode is separated from another ohmic source/drain electrode that also overlies the semiconductor film. The semiconductor film comprises a channel layer and a barrier layer that are vertically stacked and directly contact at a heterojunction. The channel layer accommodates a 2DCG that extends along the heterojunction and is ohmically coupled to the ohmic source/drain electrode and the other ohmic source/drain electrode. A gate electrode overlies the semiconductor film between the ohmic source/drain electrode and the other source/drain electrode.

  • Patent number: 11862011
    Abstract: A traffic analysis system analyzes location data from a plurality of vehicles to determine journeys made by the vehicles. Vehicles may make one or more rest stops during a journey. The traffic analysis system compares rest periods to journey criteria to determine whether a rest period delineates the end of a journey, or whether a rest period is still within the journey.
