View Edit Delete	OPT-9	As used herein, a "set screw" refers to a type of screw generally used to secure a first object within, or against, second object, usually without using a nut. Set screws can be headless, meaning that the screw is fully threaded and has no head projecting past the thread's major diameter. If a set screw does have a head, the thread may extend to the head. A set screw can be driven by an internal-wrenching drive, such as a hex socket (Allen), star (Torx), square socket (Robertson), or a slot. In one embodiment, the set screw passes through a threaded hole in the second object (an outer object) and is tightened against the first object (an inner object) to prevent the inner object from moving relative to the outer object. The set screw can exert a compressional and/or clamping force through an end of the set screw that projects through the threaded hole. (Search "set screw" on Wikipedia.com Aug. 17, 2020. Modified.

View Edit Delete	OPT-9	The separator 122 may be actuated by securing the handle 134 with one hand and then rotating the driver 152 to one or more of a plurality of displacement positions. Alternatively, or in addition, actuation of the separator 122 may include securing the gap gauge 100 in position using the handle 134, rotating the driver 152, and/or pulling on the grips 132 to separate the plates 118,120. If the handle 134 is secured, the driver 152 rotated and the grips 132 pulled to separate the plates 118,120 simultaneously or at about the same time an assistant may help with the actuation.	101	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	Figure 7 is a perspective view of an example gap gauge 100. FIGURE 7 illustrates a gap gauge 100 that includes a separator 122 that includes a cam 702 and a follower 704. As used herein, a "cam" refers to a mechanical device structured, organized, configured, programmed, designed, arranged, or engineered to translate motion of one form into motion of another form. For example, a cam can translate rotary motion into linear motion. Similarly, a cam can translate linear motion into rotary motion. A cam can be a rotating or sliding piece in a mechanical linkage used in transforming rotary motion into linear motion. A cam can be a part of a rotating wheel (e.g. an eccentric wheel) or shaft (e.g. a cylinder with an irregular shape) that strikes or moves a lever at one or more points on the rotating wheel's circular path. The cam can be a simple tooth or an eccentric disc or other shape that produces a smooth reciprocating (back and forth) motion in the follower, which is a lever configured to make contact with the cam. (Search "cam" on Wikipedia.com Dec. 26, 2020. Modified. Accessed Jan. 6, 2020.) Various types of cams can be used with the present disclosure. For example, the cam can be a radial cam, a disc cam, a cylindrical cam, or the like.	102	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	As used herein, a "follower" refers to a rigid structure that contacts a cam lobe profile. In one embodiment, the follower may translate motion of the cam to the follower and/or a structure connected to the follower. In certain embodiments, as the cam rotates the follower may slide along a contacting surface of the cam to thereby convert the rotary motion into a linear motion. A follower may also be referred to as a "cam follower" or "track follower." A cam follower is a type of structure, roller, or needle bearing designed to follow and/or contact a cam lobe profile of the cam. (Search "cam follower" on Wikipedia.com Nov. 13, 2020. Modified. Accessed Jan. 6, 2020.)	103	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	Various kinds of followers can be used in the present disclosure. The type and shape of a cam follower may be based on the kind of surface of the follower (referred to as a follower face) that contacts a contacting surface of the cam. In one embodiment, the follower is a stud that comes to a point to form a knife edge follower. Alternatively, or in addition, the follower face can have a variety of other shapes including, but not limited to a flat face, a mushroom face, a cylindrical face, a curved face, a semispherical face, and the like. In addition, the follower can include a roller on the end that contacts the contacting surface of the cam. The roller on the end of the follower can enable the follower to roll and or slide along the contacting surface of the cam.	104	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	In the illustrated embodiment, the cam 702 is connected to, or integrated with, the driver 152. The driver 152 connects to the inferior body 138 by way of the fastener 154. In this manner, the cam 702 connects to the inferior body 138. The cam 702 includes a contacting surface 706. As used herein, a "contacting surface" refers to a surface of a cam that contacts a follower. The orientation, placement, and position of the contacting surface can vary with the type of cam being used. In embodiments that use a radial cam the radial cam can have a central axis 708 and the contacting surface can be a surface of the cam that follows a circumference of the radial cam about the central axis 708.	105	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	Rotation of the driver 152 also rotates the cam 702. Rotation of the cam 702 moves the superior body 136 which adjusts the displacement of the superior plate 118 relative to the inferior plate 120. In one embodiment, the cam 702 is a radial cam and rotates about a common axis, the central axis 708, with the fastener 154. As used herein, a "radial cam" refers to a type of cam in which the cam has a central axis, and the contacting surface follows a circumference of the cam about the central axis. In a radial cam, the follower moves in a linear motion in a direction perpendicular to the central axis. The follower 704 can contact, or rest, on the cam 702.	106	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	The follower 704 is connected to the superior body 136. In one embodiment, the follower 704 may be biased against the contacting surface 706 by the spring 142 around the shaft 140. The follower 704 is sized and shaped to move the superior body 136 along the shaft 140 relative to the inferior body 138 as the follower 704 slides along, or is positioned along, the contacting surface 706. FIGURE 7 illustrates one example embodiment, in which the support plate 150 couples to the separator 122 (e.g., by way of the cam 702, follower 704, and superior body 136) such that actuation of the separator 122 moves the support plate 150 vertically relative to the inferior plate 120.	107	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	FIGURE 7 also illustrates one embodiment of a driver 152 that includes holes 710, or pockets, around the circumference of the driver 152. When the gap gauge 100 is used, a user may insert rods into the holes 710 to provide leverage for rotating the driver 152.	108	Added by DJM 2 2021	2/17/21, 12:00 AM

FIGURE 8B illustrates that the cam 702 may have an irregular radius that varies about the central axis 708. The length of the radius about the central axis 708 may be designed or engineered to achieve or maintain a desired displacement between the superior plate 118 and inferior plate 120 connected to the cam 702 and the follower 704.	110	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	Figure 9 illustrates an exploded view of an exemplary gap gauge 100, according to one embodiment of the present disclosure. FIGURE 9 illustrates details about how the hinge 156, pin 158, and needle 172 can cooperate to provide a balance indicator 126. In certain embodiments, the balance indicator 126 includes a lock-out mechanism 130 that can prevent rotation of the pivot plate 148 relative to the inferior plate 120 and/or the support plate 150 when the lock-out mechanism 130 is in a set configuration.	111	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	FIGURE 9 illustrates a support plate 150 that includes a knuckle 902 and openings 904a, 904b for at least one corresponding knuckle of the pivot plate 148. The knuckle 902 can connect the support plate 150 to the hinge 156 and the pivot plate 148. In such an embodiment, the support plate 150 and the pivot plate 148 can each serve as leaves of the hinge 156. When assembled, one or more knuckles of the pivot plate 148 align with one or more knuckles 902 of the support plate 150 and receive the pin 158. In this manner, the pivot plate 148, the pin 158, and the support plate 150 serve as a hinge to implement one embodiment of a balance indicator 126.	112	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	In certain embodiments, the pivot plate 148 may rotate freely about the pin 158. In such an embodiment, the pin 158 may include one or more pins 906. The pins 906 engage the pin 158 and the pivot plate 148 such that rotation of the pivot plate 148 causes rotation of the pin 158. In addition, if the pin 158 is fixed, or prevented from rotating about the pivot axis 162, the pins 906 may also retain the pivot plate 148 from rotating.	113	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	The pin 158 can extend within the superior body 136 and couple to the needle 172. In this manner, rotation of the pin 158 causes the needle 172 to move and point in a different direction. In certain embodiments, the pin 158 may pass through a slot in the post 146 to enable both rotation of the pin 158 and movement of the pin 158 away from the inferior body 138 when the gap gauge 100 is used.	114	Added by DJM 2 2021	2/17/21, 12:00 AM
View Edit Delete	OPT-9	FIGURE 9 illustrates a lock-out mechanism 130 that can include a set screw 908. The set screw 908 has threads that engage with threads of an opening 910 in the superior body 136. Moving the set screw 908 into the opening 910 activates the lock-out mechanism 130 and prevents rotation of the pin 158 and connected pivot plate 148. Moving the set screw 908 out of the opening 910 deactivates the lock-out mechanism 130 and permits rotation of the pin 158 and connected pivot plate 148.	115	Added by DJM 2 2021	2/17/21, 12:00 AM
