The invention, which Apple calls a 'combined input port' adds contact surfaces for the different inputs (such as USB and SD cards). With this invention, Apple could potentially find ways to put USB and SD card readers on even their smallest 11" MacBook Airs.
An input port for an electronic device for receiving different types of connectors, memory cards, or plugs. The input port includes an outer wall defining a receiving aperture, a substrate positioned within the receiving aperture. A first set of contacts is positioned on the substrate at a first depth into the receiving aperture and a second set of contacts is positioned on a first surface of the outer wall at a second depth into the receiving aperture. The first set of contacts is configured to communicate with a first connector and the second set of contacts is configured to communicate with a second connector.
While the patent is just being published today, it was originally filed in December of 2011. While Apple patents sometimes never make their way into products, the potential for this "combined input port" in smaller notebooks would be a welcomed addition.
