Abstract: A micro-electromechanical system (MEMS) based current & magnetic field sensor includes a MEMS-based magnetic field sensing component a structural component comprising a silicon substrate and a compliant layer comprising a material selected from the group consisting of silicon dioxide and silicon nitride, a magnetic-to-mechanical converter coupled to the structural component to provide a mechanical indication of the magnetic field, and a strain responsive component coupled to the structural component to sense the mechanical indication and to provide an indication of the current in the current carrying conductor in response thereto.

Abstract: A receiving container includes a lid plate thereon mounting a cylindrical receiving tube, with the cylindrical receiving tube including rotating blade members to effect crushing of glass jars and the like directed through the receiving tube from a delivery chute, with the delivery chute including a chute cover. The container may be formed of replaceable configuration to permit removal of the lid plate relative to the receiving container for selective filling of a plurality of such receiving containers.

Abstract: A portable infant changing table includes a pair of articulated mattress sections which may be folded to a more portable, compact configuration. Relatively rigid safety-side board members are attached to the mattress sections and may be raised to an upright configuration when the device is in use. The device also includes one or more pockets at the outwardly facing surfaces of the mattress sections to facilitate carrying of baby-related articles.
