A tire and a method of securing an object thereto includes a two-piece fastening system having a first portion which is applied to an innerliner of a green tire prior to the green tire being cured and a second portion which includes an object, such as a radio frequency identification chip, attached thereto. When the current-mode buck converter enters into the PFM mode, the voltage level of the parking voltage is maintained at the voltage level of compensation voltage, so as to decrease switch loss of the current-mode buck converter operating between PWM mode and PFM mode, and stabilize the output voltage of the current-mode buck converter. Said emitter is stacked on the base according to a first direction, and the base of at least one of said at least one junction has a decreasing dopant concentration gradient along said first direction. Data chunks corresponding to a subscriber are distributed across multiple devices in the mobile data network, which may include subscriber devices, network components in the mobile data network, and specialized devices provided by storage providers.
