A lid for a cup is provided with a filter fitted into a sipping hole which filters solid objects, such as tea leaves, mixed into the beverages so that pure beverage can be drunk. An illustrative lockable container may include first and second covers configured to move between an open position, which allows access to the asset, and a closed position, which encloses the asset. The eddy currents generate a voltage-inducing eddy current field in the first coil of the receiving coil arrangement. An integral horizontal connecting leg is between the legs. More specifically, in one exemplary embodiment, a device embeds alpha red green blue data in an RGB stream which allows for preservation of the alpha channel over the video interface link. The arrangement enables the backlight flashing period to be determined independently from a TFT panel scanning period or response time of liquid crystal, ensures an extended operating time of a TFT panel, effects a display period equal to, or longer than, the black blanking type, and achieves higher contrast than the black blanking type.
