A hanger system for holding glasses and a case includes a hanger made from a thin web. The detent tube has a flute to hold an inner lining. A control signal is then transmitted to user equipment via the assignment of uplink control resources. Stand-off elements having relatively high melting points can be incorporated on the BGA side of the laminate panel to ensure a minimum assembly solder collapse height. Each of the microlenses having arbitrary size are provided on the microlens plate at arbitrary positions, An outgoing angle at each microlens of divergence light or collection light is limited to a narrow angle. The front end circuit includes an analog-to-digital converter module to receive an input analog signal from the charge-coupled device sensor, the analog-to-digital converter module having a signal to noise ratio corresponding to a predetermined number of bits and a higher resolution than the predetermined number of bits.
