Abstract: Packaging of microfabricated devices, such as integrated circuits, microelectromechanical systems (MEMS), or sensor devices is described. The packaging is 3D heterogeneous packaging in at least some embodiments. The 3D heterogeneous packaging includes an interposer. The interposer includes stress relief platforms. Thus, stresses originating in the packaging do not propagate to the packaged device. A stress isolation platform is an example of a stress relief feature. A stress isolation platform includes a portion of an interposer coupled to the remainder of the interposer via stress isolation suspensions. Stress isolation suspensions can be formed by etching trenches through the interposer.

Abstract: An audit monitoring system (10) is provided for use with any of a multiplicity of different coin operated vending machines (300). The audit monitoring system includes an interface assembly (102) for use in replacing an existing data link (330) within vending machine (300) and interfacing with row and column conductors (306) of vending machine (300). The interface assembly (102) is coupled to an audit monitoring assembly (100) which interprets the communications transferred between a controller (310), coin changer (322), bill validator (324), and motor matrix (304) of vending machine (300). Audit monitoring assembly (100) is powered from a power supply (302) of vending machine (300) and includes interface circuitry (110, 120, 130, 180, 190) for receipt of digital logic level signals, serial data or relay logic signals from vending machine (300).
