Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1 and 10 – 27 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Jang et al. (US Pub. No. 2024/0126104 A1).
As to claims 1 and 21, Jang shows a head-worn display (HWD) (i.e. glasses) and associated methodology (Fig. 1 and para. 49), comprising: an optical engine (i.e. control modular 600) configured to emit a display light (i.e. image, Fig. 2 and para. 58); a lightguide (i.e. lens parts 200, Fig. 2 and para. 53); and an electrochromic facet (i.e. electrochromic module 100) configured to direct the display light such that the display light propagates through the lightguide along a path of a plurality of paths based on a state of the electrochromic facet (Figs. 7A, 7B, 8A and 8B and paras. 96 – 100).
As to claim 10, Jang shows a mirror control circuitry (i.e. reflective electrochromic layer 140), configured to control the state of the electrochromic facet (Fig. 8B and paras. 98 and 99) based on a gaze of a user (para. 60).
As to claim 11, Jang shows that the electrochromic facet is disposed within the lightguide (Fig. 8A).
As to claim 12, Jang shows a lightguide (i.e. lens parts 200, Fig. 2 and para. 53) for a head-worn display (HWD) (i.e. glasses, Fig. 1 and para. 49), comprising: one or more electrochromic facets (i.e. electrochromic module 100) configured to direct a display light (i.e. image, Fig. 2 and para. 58) such that the display light propagates through the lightguide along a path of a plurality of paths based on one or more respective states of the one or more electrochromic facets (Figs. 7A, 7B, 8A and 8B and paras. 96 – 100).
As to claims 13 and 22, Jang shows that each path of the plurality of paths corresponds to a respective portion of a field of view (FOV) area of the HWD (Figs. 7A, 7B, 8A and 8B and paras. 96 – 100).
As to claims 14 and 23, Jang shows that a first facet of the one or more electrochromic facets is configured to direct the display light such that the display light propagates through the lightguide along a first path of the plurality of paths based on a first electrochromic facet being in a first state (Figs. 7A, 7B, 8A and 8B and paras. 96 – 100).
As to claim 15, Jang shows that the first state includes a reflective state (Fig. 8B and paras. 98 and 99) and the first electrochromic facet is configured to reflect the display light such that the display light propagates through the lightguide along the first path (Fig. 8B and paras. 98 and 99).
As to claim 16, Jang shows that the first electrochromic facet is configured to transmit the display light to a second electrochromic facet of the one or more electrochromic facets based on the first electrochromic facet being in a second state (i.e. in the transmissive state, light passes through each electrochromic area, Figs. 3 and 4 and paras. 91 and 92).
As to claim 17, Jang shows that the second electrochromic facet is configured to direct the display light such that the display light propagates through the lightguide along a second path of the plurality of paths based on the second electrochromic facet being in the first state (Fig. 8B and paras. 98 and 99).
As to claim 18, Jang shows that the second electrochromic facet is configured to direct the display light such that the display light propagates through the lightguide along a third path of the plurality of paths based on the second electrochromic facet being in the second state (i.e. in the transmissive state, light passes through each electrochromic area, Figs. 3 and 4 and paras. 91 and 92).
As to claim 19, Jang shows that the one or more respective states of the one or more electrochromic facets are determined by a mirror control circuitry (i.e. reflective electrochromic layer 140) configured to control the one or more respective states of the one or more electrochromic facets (Fig. 8B and paras. 98 and 99) based on a gaze of a user (para. 60).
As to claim 20, Jang shows that the one or more electrochromic facets are disposed within the lightguide (Fig. 8A).
As to claim 24, Jang shows that the display light propagating through the lightguide along the first path of the plurality of paths is configured to illuminate a first portion of the FOV area (Figs. 7A, 7B, 8A and 8B and paras. 96 – 100).
As to claim 25, Jang shows directing, by the electrochromic facet, the display light such that the display light propagates through the lightguide along a second path of the plurality of paths based on the electrochromic facet being in a second state (i.e. in the transmissive state, light passes through each electrochromic area, Figs. 3 and 4 and paras. 91 and 92).
As to claim 26, Jang shows that the display light propagating through the lightguide along the second path of the plurality of paths is configured to illuminate a second portion of the FOV area (Fig. 4 and para. 92).
As to claim 27, Jang shows controlling the state of the electrochromic facet based on a gaze of a user (para. 60).
