Abstract: A packaging structure with a magnetocaloric material, comprising a substrate, a plurality of electrical connection structures, a die, and a sealing compound. A magnetocaloric material is added to the substrate. The die is electrically connected to the substrate through the electrical connection structures, and then encapsulated with the sealing compound. When the packaging structure is turned on, the magnetocaloric material in the substrate creates a magnetocaloric effect, which can not only take away the temperature of the packaging structure through magnetic refrigeration, but also increase the temperature difference between the packaging structure and the outside, thereby improving the efficiency of heat dissipation.

Abstract: A computer-implemented system includes one or multiple application devices and a voice-controlled storage device. Multiple voice commands may be issued to multiple application devices simultaneously or separately, or to the same application device separately. The voice-controlled storage device is configured to perform content identification and voiceprint recognition on the voice commands. Therefore, each requestor may be allowed to operate the voice-controlled storage device in a corresponding operation mode according to respective authorization level.

Abstract: A mobile phone includes a upper casing having a rail unit, a lower casing having a groove unit, and a slidable-and-rotatable mechanism that includes a slide auxiliary member, a rotatable member and a coupler shaft and that interconnects the upper and lower casings in such a manner that an assembly of the upper casing, the slide auxiliary member and the rotatable member is rotatable about the coupler shaft to a predetermined angle with respect to the lower casing once the assembly is moved to a predetermined position relative to the lower casing by virtue of sliding engagement between the rail unit and the groove unit.

Abstract: A mobile communication device is disclosed. A housing includes a receiving portion. An antenna is detachably disposed in the receiving portion and includes a first buckling portion. A rotating fastener is pivoted to the housing and includes a second buckling portion movably engaging the first buckling portion to fix the antenna to the housing.
