Abstract: Embodiments of the present invention relate to a wireless charging device. The wireless charging device includes a housing, an induction coil, a ferrite, a printed circuit board (PCB), and a fan. The housing includes a first surface and a second surface, a protrusion is disposed on the first surface, and the protrusion is configured to: support a to-be-charged device, and leave a gap between the to-be-charged device and the first surface when the to-be-charged device is installed on the wireless charging device. At least one first air guiding opening and at least one second air guiding opening are disposed on the housing. When the fan runs, the first air guiding opening, the fan, and the second air guiding opening form an air duct that passes through the ferrite and the PCB.

Abstract: A method of performing a data search in a data source by which an operator of a data search pipeline is just-in-time optimized and compiled, using an operator optimization module which optimizes and compiles an intermediate representation of the operator, considering runtime information, and optimization rules, to produce an operator that is optimized for the data search being performed. The method can be applied with one operator or with many operators applied in any sequence or tree structure according to a query plan, as determined by runtime information and optimization rules.

Abstract: The present disclosure provides an injection molding apparatus, including a fixed mold component, a movable mold component, a first positive electrode module, and a first negative electrode module. The fixed mold component has an injection port and a transmission runner, to receive injection-molding melt. The movable mold component has a molding groove communicated with the transmission runner. The first positive electrode module and the first negative electrode module are disposed on a first side and a second side of the molding groove respectively, where the first side and the second side are opposite to each other. The first positive electrode module cooperates with the first negative electrode module to form an electric field between the first side and the second side of the molding groove, to perform electric field excitation on the injection-molding melt flowing into the molding groove.
