Abstract: A physics package for chip scale atomic clocks is provided. The physics package may include a first Low-Temperature Co-fired Ceramic (LCC) pad, a first suspension coupled tothe first LCC pad, a core coupled to the first suspension, a second suspension coupled to the core and coupled to the first suspension to encapsulate the core, and a second LCC pad coupled to the second suspension and coupled to the first LCC pad to encapsulate the first suspension, the core, and the second suspension. The core may be manufactured using a wafer level fabrication process.

Abstract: A drum for a tumbler drier or washing machine is assembled from front and rear pressings and a wrapper, each secured only to a set of lifters to form a rigid construction. Plastic lifters and pre-coated metal parts eliminate a need for painting after assembly.
