Abstract: A channel encoding apparatus and method are provided in which part of the parity bits are set to erroneous bits, and full parity bits are created by correcting the erroneous bits using a channel decoding apparatus of a receiver in a communication system. In the channel encoding apparatus, in order to generate a coded bit stream by adding a parity bit stream to a message bit stream, a partial parity generator generates a partial parity bit stream as a part of the parity bit stream using the message bit stream, an erasure generator generates a bit stream having an erroneous value as the remaining part of the parity bit stream, and a decoder calculates the value of the parity bit stream by correcting the bit stream having the erroneous value using a parity-check matrix that determines the parity bit stream, the message bit stream, and the partial parity bit stream.

Abstract: A Lateral Epitaxial Gallium Nitride metal insulator semiconductor field effect transistor (LEGaN-MISFET) is described that includes a body region including at least one layer formed of Gallium Nitride having a first conductivity type formed on the substrate; a resurf layer of Gallium Nitride having a second conductivity type formed the body region; a source region in contact with the resurf layer; a drain region, in contact with the resurf layer and spaced apart from the source region; a gate metal insulator semiconductor (MIS) structure in contact with the body region including a gate contact; and a MIS conductive inversion channel along the surface of the body region in contact with the gate MIS structure. A lateral current conduction path may be formed in the resurf layer between the source region and the drain region connected by the MIS channel, where the lateral current conduction path is controlled by an applied gate source bias.

The light emitting element may include two or more light emitting diodes (LEDs) of different colors. The processing device controls the intensity of each LED to cause the light emitting element to produce the corresponding color that is substantially similar to the determined color.

Abstract: An intermediary layer is introduced between a lens and a wafer for an immersion lithography process. A non-supercritical gas is provided and condensed to form a layer of liquid between the lens and the wafer. The substrate may be irradiated through the lens and intermediary layer. In addition, the intermediary layer may then be evaporated. The non-supercritical gas may include superheated steam which may be condensed to form a layer of water between the lens and the wafer. The wafer may be irradiated with one of a EUV light and UV light. A system for introduction of an intermediary layer between a lens and a wafer for an immersion lithography process is also provided.

Abstract: A handoff method is provided in a communication network including a plurality of fixed nodes attached to a router connected to at least one external network, and at least one mobile node associated with a current fixed node. The method detects movement of a mobile node; prepares a handoff of the mobile node from a current fixed node to potential fixed nodes upon detecting movement of the mobile node; decides whether to handoff to one of the potential fixed nodes as a target fixed node; and performs the handoff from the current fixed node to the target fixed node. The handoff method enables the mobile station to quickly move its association from one access point to another by minimizing a probe delay which is a primary contributor to handoff delay.

The compact antenna device includes an antenna unit including first and second elements, the first element including a first antenna terminal having at least one of meandering and curved patterns wholly or partially, and the second element including an end connected to another end of the first element and another end having a second antenna terminal, a feeding unit exciting the antenna unit through the first and second antenna terminals, a switching circuit connected between the antenna unit and the feeding unit and selectively switching one or both of the first and second elements in order to connect one or both of the first and second elements to the feeding unit. A resonant frequency of the antenna unit varies during feeding by the feeding unit depending on the switching operation of the switching circuit.

The probing method of the present invention is implemented with a novel non-overlap graph for constructing the neighbor graph such that the probing latency is dramatically reduced, resulting in reduction of handoff delay.
