A system includes a load, one or more switches, and a controller. The taxpayer’s estimated tax refund may be based on historical tax refund data as well as current year income data. The electronic control system includes a memory, a recording mode, and a playback mode. The catch member is mounted to the pit lid for rotatable movement relative thereto. A pre-storage consistency module uses the data of the storage block, the existing parity information, and the ECC check bits to determine if the data of the storage block, the existing parity information, and the ECC check bits are consistent. In another embodiment, a method of simulating a radiation signature of an asset using quantum dots includes dispersing quantum dots to form a cloud of quantum dots; and exciting the quantum dots with a first radiation so that the quantum dots emit a second radiation having a profile similar to the radiation signature profile of the asset.
