Par. [0069] discloses the PDA software may be able to cause the PDA 38 to send and/or receive signals to and/or from a data connector 40 of the PDA 38.). Referring to claim 5, King discloses the extensions device according to claim 1, wherein the first connecting portion comprises a second hot shoe, and the second connecting portion comprises a second hot shoe head (King – Fig. 4 & par. [0097] disclose it may be possible to electrically connect a PDA to an intermediate device via the additional accessory hot shoe connector.). Referring to claim 6, King discloses the extensions device according to claim 1, wherein the electronic assembly comprises a display assembly (King – Fig. 4 & par. [0078] disclose the PDA 38 having a graphic display 74.). Referring to claim 7, note the rejections of claim 1 above. The Instant Claim recites substantially same limitations as the above-rejected and is therefore rejected under same prior-art teachings. Claim Rejections - 35 USC § 103 8. In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. 9. Claims 2 and 8 are rejected under 35 U.S.C. 103 as being unpatentable over King in view of Frank et al. (US Patent No. 7,050,107 B1 hereinafter “Frank”). Referring to claim 2, King discloses the extensions device according to claim 1, however, fails to explicitly disclose wherein the first hot shoe head is adapted to convert a first pin assignment of the first control signal to a second pin assignment and transmit the first control signal having the second pin assignment to the signal converting circuit, and the first connecting portion and the second connecting portion comply with the second pin assignment. Frank discloses wherein the first hot shoe head is adapted to convert a first pin assignment of the first control signal to a second pin assignment and transmit the first control signal having the second pin assignment to the signal converting circuit, and the first connecting portion and the second connecting portion comply with the second pin assignment (Frank – See col. 7, line 59 – col. 8, line 24). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to include Frank’s teachings with King’s techniques for the benefit of the camera and camcorder are connected securely, such that an operator can easily transport and utilize the portable system formed by the combination of the camera and camcorder (Frank – Col. 1, lines 52-58). Referring to claim 8, note the rejections of claim 2 above. The Instant Claim recites substantially same limitations as the above-rejected and is therefore rejected under same prior-art teachings. 10. Claims 3 and 9 are rejected under 35 U.S.C. 103 as being unpatentable over King in view of Fritchman et al. (US Pub. No. 2014/0075061 A1 hereinafter “Fritchman”). Referring to claim 3, King discloses the extensions device according to claim 1, however, fails to explicitly disclose wherein the signal converting circuit is adapted to convert the first control signal having a first voltage level to the second control signal having a second voltage level. Fritchman discloses wherein the signal converting circuit is adapted to convert the first control signal having a first voltage level to the second control signal having a second voltage level (Fritchman – See par. [0010, 0033]). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to include Fritchman’s teachings with King’s techniques for the benefit of an adapter for providing connectivity between a host connector of a host device and an accessory connector of an accessory that is incompatible with the host connector (Fritchman – Abstract). Referring to claim 9, note the rejections of claim 3 above. The Instant Claim recites substantially same limitations as the above-rejected and is therefore rejected under same prior-art teachings. 11. Claims 4 and 10 are rejected under 35 U.S.C. 103 as being unpatentable over King in view of Miyazaki (US Pub. No. 2021/0373083 A1 hereinafter “Miyazaki”). Referring to claim 4, King discloses the extensions device according to claim 1, however, fails to explicitly disclose wherein the electronic assembly further comprises a voltage divider circuit and a function-executing element, the voltage divider circuit is electrically connected to the second connecting portion and the processing circuit, the function-executing element is electrically connected to the processing circuit, the voltage divider circuit is adapted to transmit an executing signal to the processing circuit after the processing circuit receives the second control signal, and the processing circuit is adapted to transmit the executing signal to the function-executing element. Miyazaki discloses wherein the electronic assembly further comprises a voltage divider circuit and a function-executing element, the voltage divider circuit is electrically connected to the second connecting portion and the processing circuit, the function-executing element is electrically connected to the processing circuit, the voltage divider circuit is adapted to transmit an executing signal to the processing circuit after the processing circuit receives the second control signal, and the processing circuit is adapted to transmit the executing signal to the function-executing element (Miyazaki – See par. [0020, 0027-0029]). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to include Miyazaki’s teachings with King’s techniques for the benefit of an electronic device can be controlled depending on whether predetermined information has been obtained from a battery (Miyazaki – Par. [0004]). Referring to claim 10, note the rejections of claim 4 above. The Instant Claim recites substantially same limitations as the above-rejected and is therefore rejected under same prior-art teachings.
