Regarding claim 10, Froment discloses wherein the lug nest (411) is a first lug nest (lug nest on I in annotated Figure 5 above), and further including a second lug nest (411 on H in annotated Figure 5 above) located proximate the second limit surface of the second channel (406 on H in annotated Figure 5 above), the second lug nest having a second curved inner surface (see Fig. 5 for example). Regarding claim 11, Froment discloses wherein the latch (B in Fig. 4) does not include a third channel or a third lug nest (see Fig. 5 and see Column 3 lines 43-48). Regarding claim 12, Froment discloses wherein the curved inner surface (see 411 in Fig. 5) is an arced inner surface (see Fig. 5 for example). Regarding claim 13, Froment discloses wherein the curved inner surface (see 411 in Fig. 5) is a U-shaped inner surface (see Fig. 5 for example). Regarding claim 14, Froment discloses wherein the curved inner surface (see 411 in Fig. 5) is a concave inner surface (see 411 in Fig. 5). Regarding claim 15, Froment discloses further including a lug ramp (K in annotated Figure 5 below) coupled to the lug nest (411) such that an elongated lug (20) of a hook may engage the lug ramp prior to nesting in the lug nest (see Fig. 5 for example). PNG media_image7.png 438 473 media_image7.png Greyscale Figure 7. Annotated Figure 5. Regarding claim 16, Froment discloses wherein the lug ramp (K in annotated Figure 5 above) includes an angled inner surface (see Fig. 5) leading to the lug nest (411) and configured to assist with tilt correction (see NOTE below). NOTE: The lug ramp is capable of assisting with tilt correction. Regarding claim 17, Froment discloses wherein the angled inner surface (K in annotated Figure 5 above) is a V-shaped inner surface (see Fig. 5). Regarding claim 18, Froment discloses a pick-and-place system (see Fig. 4), comprising: a hook (A in Fig. 4), including: an elongated member (A in Fig. 4) having a first end (end of A comprising 20-21) and a second end (end of A opposite 20-21); two or more pins (20-21) coupled proximate the first end of the elongated member (see Fig. 4); and one or more elongated lugs (14 in Fig. 3) positioned substantially parallel with the elongated member (see NOTE below) between the two or more pins and the second end (see Fig. 4); and a latch (B in Fig. 4) coupleable with the hook, the latch including: a latch member having a central axis (X in Fig. 4) and a surface (F in annotated Figure 4 above) surrounding the central axis (see Fig. 4), the latch member having a first upper portion (G in annotated Figure 5 above) and second (H in annotated Figure 5 above) and third (I in annotated Figure 5 above) lower portions extending radially from the surface (see Figs. 4-5), the second and third lower portions circumferentially spaced from one another and axially spaced from the first upper portion (see Fig. 5), guide and limit surfaces of the second and third lower portions facing respective guide and limit surfaces of the first upper portion (see Fig. 5) that cooperate to form first and second channels (40-41), the first and second channels being similarly shaped (see Fig. 5), each of the first and second channels having in order a first upwardly sloping path (402-403) defined by a respective first upwardly slanting guide surface (see J in annotated Figure 5 above) and a first limit surface (404) of the first upper portion, a second downwardly sloping path (405) defined by a respective second downwardly slanting guide surface (405) and a second limit surface (406) of a respective lower portion, and a third upwardly sloping path (407) defined by a respective third upwardly slanting guide surface (407, see Fig. 5) and a third limit surface (408) of the first upper portion, the first and second channels configured to each receive one of the two or more pins (20-21) of the hook; and a lug nest (L in annotated Figure 3 below) located proximate the second limit surface of the first channel (see Fig. 3 for example), the lug nest having a curved inner surface (see Fig. 4 for example). NOTE: The surfaces of the lug member 14 in Fig. 3 are substantially parallel to the surfaces of the elongated member as seen in at least Fig. 3. PNG media_image8.png 508 572 media_image8.png Greyscale Figure 8. Annotated Figure 3. Regarding claim 19, Froment discloses wherein the two or more pins (20-21) of the hook (A in Fig. 4) are located within the first and second channels (40-41) of the latch (B in Fig. 4). Regarding claim 20, Froment discloses wherein one of the one or more elongated lugs (14 in Fig. 3) is nested within the lug nest (L in annotated Figure 3 above). Regarding claim 21, Froment discloses wherein one of the one or more elongated lugs (14 in Fig. 3) is sufficiently spaced from the one or more pins (20-21, see Fig. 3) to prevent the one or more elongated lugs from fitting between the first upper portion and the second or third lower portions (see Fig. 3). Regarding claim 22, Froment discloses wherein one of the one or more elongated lugs (14 in Fig. 3) is spaced from the one or more pins (20-21) by at least a maximum straight-line distance from the first limit surface to the second downwardly-sloping guide surface (see NOTE below). NOTE: The distance between the elongated lug and the one or more pins is shown by N in annotated Figure 1 below. The maximum straight line distance from the first limit surface to the second downwardly sloping guide surface is shown by M in annotated Figure 1 below. Accordingly, N extends at least the distance of M as seen below. PNG media_image9.png 528 739 media_image9.png Greyscale Figure 9. Annotated Figure 1.
