Abstract: A polarizing plate and an optical display apparatus are disclosed. A polarizing plate includes a polarizer and a stack of retardation layers on a surface of the polarizer, and the stack of retardation layers includes a second retardation layer and a first retardation layer stacked on the polarizer in sequence from the surface of the polarizer, the second retardation layer being a non-liquid crystal layer, and the stack of retardation layers has an out-of-plane retardation of ?40 nm or more to less than 0 nm at a wavelength of 550 nm and satisfies Relation 1.

Abstract: The present disclosure relates to a motion retargeting method and apparatus for character animation, and the method may include generating an intermediate object including at least one of a skeleton and a mesh based on a source motion and a target character, extracting keyframes of the intermediate object, constituting target rig parameters based on the extracted keyframes, and performing spacetime optimization on the target rig parameters to minimize a pose error between the intermediate object and the target character.

Abstract: Methods of managing a key cache are provided. One method may include determining whether a given key has previously been loaded to a trusted platform module (TPM), loading the given key to the TPM and generating a key cache object corresponding to the given key if the determining step determines the given key has not previously been loaded to the TPM and restoring the given key to the TPM based on the key cache object corresponding to the given key if the given key has previously been loaded. Another method may include extracting a key from a TPM if the TPM does not have sufficient memory to load a new key, the extracted key corresponding to a least frequently used key cache object within the TPM. Another method may include restoring a key to a TPM, the restored key having been previously loaded to and extracted from the TPM.

Abstract: The present invention relates to the heat-radiation structure of a pin-type power Light Emitting Diode (LED). The heat-radiation structure includes an LED device, first and second lead frames, a mold unit, and a heat sink. The first lead frame is electrically connected to the LED device, and extended forward to the outside in order to supply power to the LED device. The second lead frame is provided to face the first lead frame, and extended forward to the outside. The mold unit includes the LED device, and molds the upper portions of the first and second lead frames out transparent material. The heat sink is provided at a bottom of the mold unit so that the lead frames penetrate therethrough, fixed into any of the two lead frames, and configured to receive heat from the lead frame which comes into contact therewith and to radiate the heat to the outside.

Abstract: Methods of managing a key cache are provided. An example key cache management method may include determining whether a given key has previously been loaded to a trusted platform module (TPM), loading the given key to the TPM and generating a key cache object corresponding to the given key if the determining step determines the given key has not previously been loaded to the TPM and restoring the given key to the TPM based on the key cache object corresponding to the given key if the determining step determines the given key has previously been loaded to the TPM.
