Abstract: An electrical connector can receive a substrate having conductive tracks. The connector includes a housing with a port and at least one alignment feature that together define a direction of insertion. At least three function pins mounted to the housing each include contacts that electrically connect to one of the conductive tracks of a substrate inserted in the connector. A sense pin mounted to the housing has a contact that electrically connects to at least one of the conductive tracks of an inserted substrate. The sense pin can include a plurality of electrically-connected segments, each segment extending substantially parallel or substantially perpendicular to the direction of insertion of the substrate. Systems and methods for detecting an analyte in a bodily-fluid sample are also described.

Abstract: A power generation device generates power by subjecting a composite of magnetostrictive material and piezo material to a magnetic field. The composite of magnetostrictive material and piezo material may be incorporated in a battery or other storage device.

Abstract: A detachable wheel mask for temporarily covering an entire wheel of an automobile during washing for the purpose of protecting the wheel from dirt while cleaning an associated tire is disclosed. The wheel mask includes a circular protective cover of a size corresponding with the wheel, a retaining element for fitting within a nip formed between the wheel rim and the tire to secure the protective cover to the wheel rim enclosing the wheel and a handle.
