Gleason in view of Zhang does not explicitly disclose the electrochromic glass shutter includes an electrochromic glass layer having a first material coating of lithium ions an electrochromic glass layer and a second material coating of a transition metal oxide layer such that a first voltage across the electrochromic glass layer with the first material coating and the second material coating causes a first state of opacity blocking light from reaching the aperture of the camera and a second voltage across the electrochromic glass layer with the first material coating and the second material coating causes a second state that is transparent to permit light to reach the aperture of the camera.
Glik teaches, from the same field of endeavor that in an electrochromic glass shutter (Para. 0061 and 0063) that it would have been desirable to make the electrochromic glass shutter includes an electrochromic glass layer having a first material coating of lithium ions an electrochromic glass layer (Para. 0063, lines 6-23; discloses an ion storage layer (e.g., lithium cobalt oxide (LiCoO2))) and a second material coating of a transition metal oxide layer (Para. 0063, lines 6-23; discloses a first conducting oxide layer (e.g., tungsten oxide (W03)) such that a first voltage across the electrochromic glass layer with the first material coating and the second material coating causes a first state of opacity blocking light from reaching the aperture of the camera (Para. 0062-0063) and a second voltage across the electrochromic glass layer with the first material coating and the second material coating causes a second state that is transparent to permit light to reach the aperture of the camera (Para. 0062-0063).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to make the electrochromic glass shutter includes an electrochromic glass layer having a first material coating of lithium ions an electrochromic glass layer and a second material coating of a transition metal oxide layer such that a first voltage across the electrochromic glass layer with the first material coating and the second material coating causes a first state of opacity blocking light from reaching the aperture of the camera and a second voltage across the electrochromic glass layer with the first material coating and the second material coating causes a second state that is transparent to permit light to reach the aperture of the camera as taught by the electrochromic glass shutter of Glik in the combination of Gleason in view of Zhang since Glik teaches it is known to include these features in an electrochromic glass shutter for the purpose of providing a low-cost electrochromic glass shutter with reduced color aliasing that avoids the use of moving parts while at the same time achieving improved focusing and greater depth of field.
Gleason, Zhang and Glik does not explicitly disclose the circuit switch to receive a voltage to change the opacity of the electrochromic glass camera privacy shutter to occlude light external to the chassis from reaching within the chassis in a first state and to permit light external to the chassis to reach within the chassis in a second state, and the electrochromic glass camera privacy shutter formed external to the camera components including the lens of the camera and electronic image capture component including controls for exposure and image capture.
Ollila teaches, from the same field of endeavor that in an information handling system (Fig. 8) that it would have been desirable to make the circuit switch (Para. 0033 and 0081; note, discloses using a controller to activate an electrochromic glass privacy shutter) to receive a voltage to change the opacity of the electrochromic glass camera privacy shutter (Para. 0078 and see 556) to occlude light external to the chassis (544) from reaching within the chassis in a first state (Para. 0061; note, discloses blocking and rejecting light) and to permit light external to the chassis to reach within the chassis in a second state (Para. 0061; note, discloses the privacy shutter is fully transmissive to transmit light), and the electrochromic glass camera privacy shutter (556) formed external to the camera components (546 and 548) including the lens of the camera (546) and electronic image capture component (548) including controls (Figs. 1 and 16) for exposure and image capture (see 104 of Fig. 1 and see 2, 4 of Fig. 16).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to make the circuit switch to receive a voltage to change the opacity of the electrochromic glass camera privacy shutter to occlude light external to the chassis from reaching within the chassis in a first state and to permit light external to the chassis to reach within the chassis in a second state, and the electrochromic glass camera privacy shutter formed external to the camera components including the lens of the camera and electronic image capture component including controls for exposure and image capture as taught by the information handling system of Ollila in the combination of Gleason, Zhang and Glik since Ollila teaches it is known to include these features in an information handling system for the purpose of providing a compact, fast, reliable and low power information handling system.
Regarding claim 18, Gleason, Zhang, Glik and Ollila discloses and teaches as set forth above, and Gleason further discloses, a cable connection (see annotated Fig. 2 below) operatively coupling the camera and electrochromic glass layer to an embedded controller (EC) operating below a basic input/output system (BIOS) (Para. 0003, 0026-0028 and see 15, 17) executed by the processor of the information handling system (Para. 0026-0028 and 0040-0042).

Regarding claim 19, Gleason, Zhang, Glik and Ollila discloses and teaches as set forth above, and Gleason further discloses, the PMU operatively coupled to the EC and the PCB (see annotated Fig. 2 above), the EC to control the voltage (Para. 0004-0005, lines 11-15 and 0040-0042; describes a variable voltage that is used to change the active electrochromic glass shutter between clear and dark states; as desired) to the electrochromic glass camera privacy shutter via a circuit switch (Para. 0026-0028 and see 15, 17).
Regarding claim 20, Gleason, Zhang, Glik and Ollila discloses and teaches as set forth above, and Gleason further discloses, a circuit switch (Para. 0026-0028 and see 15, 17) operatively coupled to the electrochromic glass camera privacy shutter with a first voltage sent to the electrochromic glass camera privacy shutter to switch to the first state to turn it opaque and occlude light to an image capture component of the camera (Para. 0038-0040; discloses a dark aperture stop state), and a second voltage sent to the electrochromic glass camera privacy shutter to switch to the second state to make the electrochromic glass layer transparent (Para. 0004-0005, lines 11-15 and 0040-0042; describes a variable voltage that is used to change the active electrochromic glass shutter between clear and dark states; as desired) and transmit light to the image capture component of the camera (Para. 0038-0040; discloses a clear state that transmits at least 95% of light), the circuit switch to receive input from the EC to change the opacity of the electrochromic glass camera privacy shutter between the first state and the second state (Para. 0004-0005, lines 11-15 and 0040-0042; describes a variable voltage that is used to change the active electrochromic glass shutter between clear and dark states; as desired).
Furthermore, Ollila teaches, from the same field of endeavor that in an information handling system that it would have been desirable to make the electrochromic glass layer opaque to block external light from reaching within the chassis of the information handling system (Para. 0026; note, discloses the cover element 605 (Para. 0061; note, discloses blocking and rejecting light).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include the above mentioned limitations as taught by the information handling system of Ollila in the combination of Gleason, Zhang and Glik since Ollila teaches it is known to include these features in an information handling system for the purpose of providing a compact, fast, reliable and low power information handling system.
Response to Arguments
