An apparatus and method for processing optical information using a low density parity check code are suggested. An optical information recording method includes the steps of encoding data to record into a low density parity check code; representing the data, which is encoded into the low density parity check code, to a spatial light modulator in the unit of a data page; and modulating a recording beam into the data page representing the spatial light modulator to be recorded in the form of hologram in a recording medium. By blocking inexact probability information from being concentrated in the LDPC code block, by achieving exact probability information through effective allocation of a mark, and by improving average accuracy of the pixel, which corresponds to the LDPC code, failure rate of decoding can be minimized so that decoding performance can be improved.

System and method for generating secured authentication image files for use in device authentication
A secure authentication image file is generated for use in authenticating a device. The device performs a secure authentication algorithm on the secure authentication image file and a received plaintext challenge, and outputs a cyphertext response.

In a control apparatus of a vehicle according to an embodiment of the present invention, there is a failsafe control that blocks power transmission from a drive source to drive wheels by releasing clutches of an automatic transmission when there is a shift switching failure. In consideration of the fact that when a working oil temperature of the automatic transmission is low (below the freezing point, for example), the viscosity of the working oil is high and response for power blocking is poor, in a case where an oil temperature at the time of a shift switching request is low (steps ST2 and ST3), the power transmission is blocked by releasing the clutches of the automatic transmission at the same time as the shift switching request (step ST11). Thus, a clutch release delay occurring when there is a shift switching failure at a low oil temperature is prevented.

Unified mobility switches often define a virtual LAN (VLAN), including a combination of mobility tunnels and access tunnels, via which packets are transported to a mobile device over a combination of physical connections and wireless links. A unified switch may have multiple ports available to route a packet to a particular destination, since the unified switches identify routing paths for both physical connections and VLANs. A particular unified switch may therefore have multiple routes to a common destination, which can lead to a routing loop across a network of switches supporting both physical and virtual connections. A unified mobility switch provides loop detection and prevention through a set of rules for qualifying connections as virtual tunnels or physical connections, and defining a single path where multiple potential paths exist.

The output match network is operable to provide a range of impedance matching over a signal bandwidth and a low frequency gain peak outside the signal bandwidth which corresponds to a low frequency resonance of the high quality factor RF path. The bypass network is coupled in parallel with the blocking capacitor of the output match network. The bypass network is operable to attenuate the low frequency gain peak while maintaining the high quality factor RF path.

Various circuit techniques for implementing ultra high speed circuits use current-controlled CMOS (C3MOS) logic fabricated in conventional CMOS process technology. An entire family of logic elements including inverter/buffers, level shifters, NAND, NOR, XOR gates, latches, flip-flops and the like are implemented using C3MOS techniques. Optimum balance between power consumption and speed for each circuit application is achieve by combining high speed C3MOS logic with low power conventional CMOS logic. The combined C3MOS/CMOS logic allows greater integration of circuits such as high speed transceivers used in fiber optic communication systems.
