A wireless resource allocation method considering retransmission in a wireless communication system is provided. A cavity in the base of the lamp socket is provided to accept a lamp configured with an extension extending from the base of the lamp and providing a vertically mounted electrical contact in the cavity that can only be contacted by a lamp contact that is placed at the end of the lamp base extension. The system also has a power supply for providing at least five thousand volts of power to the light emitting device, and the electrons transiting from cathode to anode are essentially unfocused. It is determined whether each of the raw signals satisfies any condition in a condition group, and the raw signal satisfying any condition in the condition group is mapped to one of a plurality of preset constants to generate a plurality of first data. The etching method further includes etching the second oxide film and the first oxide film, thereby forming a hole reaching the contact portion, and etching the first oxide film by a dry process using a gas containing HF, thereby expanding a portion of the hole adjacent to an upper side of the contact portion and inside the first oxide film. In a preferred embodiment of the invention, the detector is a silicon avalanche photodiode that provides a two dimensional position sensitive readout for each event that is detected.
