In alternative example embodiments, a single magnet array may be embedded either within a removable lens coupling interface or within a lens attachment interface within the case or mobile device. The single ferromagnet or ferrimagnet array may couple in these alternative example embodiments to paramagnetic material provided within the other interface that does not contain a ferromagnetic or ferrimagnetic array.
In alternative example embodiments, ferrite magnets may be used to form all of part of a magnet array that is embedded within a mobile smart device case, accessory and/or accessory interface device. A mobile smart device may include a magnet array formed in whole or in part by ferrite magnets and/or by ferromagnets. In certain example embodiments, hard ferrite magnets such as Barium hexaferrite and/or Strontium hexaferrite may be used to form all or part of a ferrimagnetic array.
The coupling interface of the removable lens assembly may include a bayonet tab. The lens attachment interface may include a detent portion that at least partially defines a lens attachment cavity that is shaped in accordance with the bayonet tab of the removable lens assembly to stably couple and align the removable lens along the optical path of the miniature camera module of the mobile device. The bayonet tab may be configured with an oblong and/or curved shape in accordance with any of several removable lens embodiments and lens attachment interface embodiments described herein. A case may be configured in accordance with the coupling interfaces of the removable lens and lens attachment interface as described in various embodiments herein.
While an exemplary drawings and specific embodiments of the present invention have been described and illustrated, it is to be understood that that the scope of the present invention is not to be limited to the particular embodiments discussed. Thus, the embodiments shall be regarded as illustrative rather than restrictive, and it should be understood that variations may be made in those embodiments by workers skilled in the arts without departing from the scope of the present invention.
In addition, in methods that may be performed according to preferred embodiments herein and that may have been described above, the operations have been described in selected typographical sequences. However, the sequences have been selected and so ordered for typographical convenience and are not intended to imply any particular order for performing the operations, except for those where a particular order may be expressly set forth or where those of ordinary skill in the art may deem a particular order to be necessary.
A group of items linked with the conjunction “and” in the above specification should not be read as requiring that each and every one of those items be present in the grouping in accordance with all embodiments of that grouping, as various embodiments will have one or more of those elements replaced with one or more others. Furthermore, although items, elements or components of the invention may be described or claimed in the singular, the plural is contemplated to be within the scope thereof unless limitation to the singular is explicitly stated or clearly understood as necessary by those of ordinary skill in the art.
The presence of broadening words and phrases such as “one or more,” “at least,” “but not limited to” or other such as phrases in some instances shall not be read to mean that the narrower case is intended or required in instances where such broadening phrases may be absent. The use of the terms “system” or “assembly” does not imply that the components or functionality described or claimed as part of the assembly are all configured in a common package. Indeed, any or all of the various components of a system, e.g., a case and a lens attachment interface may be combined in a single package or separately maintained and may further be manufactured, assembled or distributed at or through multiple locations.
