Abstract: The disclosed subject matter relates to liquid metal interconnects for power semiconductor modules. For example, disclosed herein are semiconductor package devices, comprising: a semiconductor device comprising an electrode and/or contact pad; a solid metal circuit element; and a liquid metal interface comprising a liquid metal material. The liquid metal interface can append at least a portion of the solid metal circuit element to at least a portion of the electrode and/or contact pad within a contact area. Adhesive forces, cohesive forces, surface tension forces, capillary forces, viscosity, and/or wetting characteristics enable containment of the liquid metal interface within the contact area. Also disclosed herein are methods of making and use of any of the devices disclosed herein.

Abstract: An exercise device (10) comprises a kit of parts comprising a carrier structure (12) and a plurality of ballast elements (20, 22), wherein the carrier structure (12) comprises a carrier body (12a) with at least two attachment locations (14a-d, 16a-d), and wherein the ballast elements (20, 22) comprise two engaging structures (20a, 20b, 22a, 22b), a first one of the engaging structures (20a, 22a) being configured for connection with an attachment location (14a-d, 16a-d), and a second one of the engaging structures (20b, 22b) being configured like an attachment location (14a-d, 16a-d) of the carrier, for connection with the first engaging structure (20a, 22a) of another ballast element.

Abstract: An animal toy includes a generally spherical center portion having an opening, a slidable door configured to close the opening, and a plurality of flexible legs. The slidable door is configured to frictionally fit within open such that the door is capable of being in an open position, a closed position and a partially opened position. Each of the plurality legs includes an arcuate portion so as to at least partially surround the generally spherical center portion.

Abstract: An animal food dispenser, includes a base portion and a roller portion. The base portion has first and second upwardly extending members. The roller portion has an opening, and is configured to be held by the upwardly extending members such that the roller portion is capable of freely rotating and dispensing food through the opening.

Abstract: A pet toy is basically provided with a retractable portion and a connector. The retractable portion has a housing and a cord connected to the housing. The connector has a cord attachment part and a toy attachment part. The cord attachment part is configured to be connected to an end of the cord. The toy attachment part has a hinge that pivots about a hinge axis to open and close the toy attachment part.
