Heat from a heat generating device such as CPU is dissipated by a heat sink device containing a recycled two-phase vaporizable coolant. In an exemplary embodiment, an antenna assembly generally includes one or more tapered loop antenna elements. If a data error is detected, these mappings allow the data storage service to search the one or more data stores for data blocks having matching hash values. The tension sensing assembly further includes a cable extending through the housing and cooperable with the movable mechanism to move the movable mechanism to deflect the at least one spring. A receiving cavity for a piston rod is created in the piston section.
