Abstract: The present invention relates to the field of pharmaceutical chemistry, and specifically relates to a fused heterocyclic compound derivative and an application thereof. The fused heterocyclic compound derivative has the structure of general formula (I), and can be used to treat neuropsychiatric diseases.

Abstract: Embodiments of the present disclosure provide a positioning structure and a flexible printed circuit. The positioning structure includes a flexible substrate having a positioning hole therein and a reinforcing layer disposed on the flexible substrate and located within a preset range around a periphery of the positioning hole to reinforce the positioning hole, and the reinforcing layer includes a first hole corresponding to the positioning hole. In the positioning structure according to the embodiments of the present disclosure, the strength of the positioning hole is improved and an undesirable deformation phenomenon of the positioning hole under action of external forces is prevented, by disposing the positioning hole on the flexible substrate and laying the reinforcing layer in the preset range around the periphery of the positioning hole.

Abstract: An insulating housing with integrated functions comprises a barrel-shaped shell, an interior wall of which being provided with a protruded or recessed uneven texture configured to increase a creepage distance between both axial ends of the barrel-shaped shell, the path of the creepage distance formed by the protruded or recessed uneven texture having more than two flyover or bypass sub-paths, such that the creepage distance is increased, and the voltage withstanding is increased.

Abstract: A method and an apparatus is provided for conducting wireless data communications using whitespace and non-whitespace channels. A short-range base station with an interface for whitespace channels and another interface for non-whitespace channels communicates with user equipment outfitted with equivalent interfaces. The short-range base station has a preference for using the interface for the whitespace channels, where the whitespace channels are whitespace spectrum bands that are available during periods when a primary user is not actively utilizing the whitespace. A spectrum server analyzes spectrum occupancy database information and whitespace spectrum sensing measurements to determine lists of available whitespace spectrum bands for use by the short-range base station.

Abstract: A method and apparatus is described for forming and using a stiffener for the production of thinned integrated circuits. In one embodiment, a handle can be bonded to an integrated circuit wafer before the wafer is thinned. Electrical couplings such as mounting balls can be attached to the wafer. Individual dice can be singulated from the wafer by dicing through the wafer and the handle, producing a wafer/handle assembly. The wafer/handle assembly can be mounted to a printed circuit board before the handle is de-bonded.
