A semiconductor package having a lead frame formed with a die pad and a plurality of conductive leads, wherein the die pad is formed with a plurality of tabs to impede the resin flow below the die pad such that a downward pressure is produced because the resin flow above the die pad moves at a speed faster than that below the die pad. The wireless communication element is utilized for performing a wireless communication with a set-up box of the display device. When the valve needs to be split in order to clear a medical device such as a pacemaker lead, the sleeve is split and the valve is disassembled. The calibration module calibrates the first image data according to at least one selected optical parameter of the second optical subsystem, and calibrates the second image data according to at least one selected optical parameter of the first optical subsystem. A vascular lesion can be selectively imaged by using a contrast medium comprising a liposome containing said compound or a salt thereof. This blend can then be dissolved in water to make a solution of between about 1% total solids by weight up to the saturation point, which can be used as an antimicrobial solution for food safety applications.
