  • Patent number: 8720975
    Abstract: A vehicle apparatus comprises a slider body having a substantially vertical slide slot and a substantially horizontal shear pin. The slider body further includes a headlamp mounting section and a hood bump-stop mounting section. An adjustable bumper is received by the hood bump-stop mounting section with an adjustable height. A reinforcement member is configured to be fixed with respect to a grille opening of the vehicle. The reinforcement member has a bore aligned with the slide slot for receiving a fastening pin and an aperture receiving the shear pin. A force greater than a predetermined force applied to the adjustable bumper results in the shear pin breaking off in the bore and the fastening pin sliding along the slide slot as the slider body moves downward.

  • Patent number: 8665193
    Abstract: An OCB (Optically Compensated Bend) liquid crystal display in which impulse driving is performed such that an impulse data voltage is applied between normal data voltages used for displaying an image. The impulse data voltage is divided into a first impulse data voltage and a second impulse data voltage having a voltage value that will not break a bent alignment of the OCB liquid crystals. Referring to the application of the first impulse data voltage between the normal data voltages as first impulse driving and the application of the second impulse data voltage between the normal data voltages as second impulse driving, the second impulse driving is performed at every two or more of the first impulse drivings, so as to not break the bent alignment of the liquid crystals and to thereby improve luminance of the LCD.

  • Patent number: 8521171
    Abstract: A method for allocating resource regions in a wireless access system. This method collectively allocates resources in non-consecutive frames. Specifically, a message, including allocation information used to collectively and non-consecutively allocate identical resource regions, is received from a base station and data is transmitted or received through the allocated resource regions. Since identical resource regions are collectively allocated in multiple frames, it is possible to reduce both the number of transmissions of a MAP message and MAP overhead in a network.
