摘要： Disclosed herein are a CDMA optical system and encoder and decoder included therein. Time domain encoding means creates a time domain code having a sequence according to inputted data bits or a complementary code which is complementary to the time domain code. An optical modulation means selectively outputs lights, in which the lights are incident upon the optical modulation means from the outside, to two output leads, respectively, according to chip bits of the time domain code or the complementary code. A wavelength domain encoding means encodes the light outputted from a first output lead of the optical modulation means to a wavelength domain sequence (two dimensional code), transmits the wavelength code to the base station, encodes the light outputted from a second output lead to a complementary sequence of the wavelength domain sequence, and transmits the complementary code of the two dimensional code to the base station.

摘要： A two-dimensional wavelength/time optical CDMA system employing balanced-modified pseudo random noise (PN) matrix codes is provided. Through an inverse-exclusive OR operation of a pair of modified PN code, the balanced codes are generated as optical CDMA codes in the form of a new matrix. When the codes are applied to an optical CDMA system to perform encoding and decoding, if the same number of channels as the number (M−1) of subgroups of the codes are connected, the system becomes an MAI-free system, and even if the number of channels connected is twice the number of the subgroups, an error-free system can be established. Accordingly, the number of channels that can be used simultaneously is doubled compared to the prior art method such that the economical efficiency of the optical CDMA system improves.

摘要： A novel electronic system for third-party service portal-initiated garment service bag creation, distribution, volumetrically-standardized pricing, and matchmaking of professional garment cleaning is disclosed. The novel electronic system physically issues and electronically tracks volumetrically-standardized online garment service bags that are shipped to potential customers, who can then utilize such service bags to load garments at volumetrically-standardized fees per service bag and transport to a plurality of independent local garment cleaning service providers subscribed to the third-party service portal. The novel electronic system also enables the plurality of independent local garment cleaning service providers to define and competitively offer garment cleaning service fees that are objectively price-comparable on a price-per-unit bag metric of laundry load due to the volumetric standardization and the pre-distribution of online garment service bags by the third-party service portal, even before the potential customers utilize such service bags to load and ship garments to garment cleaning service providers.

摘要： A first signal input circuit outputs a first control signal in response to self-refresh and active signals. A second signal input circuit outputs a second control signal in response to the self-refresh and active signals. The power supply circuit applies a first supply voltage to an output terminal in response to the first control signal. An elevated voltage generator generates a elevated voltage by pumping a second supply voltage, and applies the elevated voltage to the output terminal, in response to the first and second control signals.
