Abstract: The invention provides a method and apparatus for allocating a dynamic band width of an EPON and an EPON master apparatus using the same. The bandwidth allocation is cycle based where every predetermined cycle, static gates are generated for all ONUs and dynamic gates are generated according to the reports using the remaining grant resource. The method for allocating an upstream bandwidth to transmit data from the ONUs to an OLT is as follows. A total allocatable grant length is calculated for the given cycle. A requested amount of grant length needed to transmit upstream data in each ONU is set based on report values collected from the report frames from all ONUs in the EPON. Then, distribution is made sequentially and repeatedly in a cycle by taking a basic unit from the total grant length and adding it to the grant length of the ONUs until the total allocatable grant length becomes 0 or the grant length allocated to all ONUs satisfy the requested amount of the grant length set in all ONUs.

Abstract: Provided is a field effect transistor (FET) type biosensor including a source electrode, a gate, and a drain electrode. A ligand that can bind to a side of a nucleic acid is added to the surface of the gate. In a conventional FET type biosensor, it is difficult to detect a signal within the debye length because a target nucleic acid is directly fixed to the surface of a gate of the conventional FET. However, in the present invention, this problem can be overcome and the debye length can be increased by treating the surface of a gate of an FET sensor with a ligand that can bind to a side of a nucleic acid. The ligand can be adsorbed onto the surface of the gate. In this case, the nucleic acid is adsorbed parallel to the surface of the gate, not perpendicular to the surface of the gate, thus generating an effective depletion region. In addition, hybridization efficiency can be increased because a hybridized sample can be injected into an FET sensor at high ionic strength.

A target material need not be labelled, a signal processing of a fluorescent or electrical detection signal using an analysis apparatus is not required, and a signal can be directly decoded by confirming whether a current flows through the switch.
