DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0037] Illustrated in FIG. 6A is, generally, a connector position assurance (CPA) device 10 and a connector assembly housing 20, the CPA device 10 and the housing 20 being shown separately. The housing 20 has an upper surface 30, wherein the upper surface 30 includes a retention portion 25 for accommodating therein the CPA device 10. The CPA device 10 may be a known and a well-established component with a well-understood functionality within the industry of connector assemblies and the industries using such devices. Generally, the CPA device 10, when in a full-lock position relative to the housing 20, ensures that a male terminal and a female terminal (not shown) housed within the housing 20 are fully engaged. Shown on an upper surface 23 of the CPA device 10 is a first visible or visual surface 28 capable of being detected by a machine or electric/electronic scan system 40 (see FIG. 7A). Also shown in FIG. 6A is a second visible or visual surface 32 on the upper surface 30 of the housing 20 similarly capable of being detected by the machine or electric/electronic scan system 40 (see, again, FIG. 7A).

[0038] In FIG. 6B, the CPA device 10 is accommodated within the retention portion 25 located in the upper surface 30 of the housing 20. As shown in FIG. 6B, the CPA device 10 is in a pre-lock position and ready to be pushed or moved in the direction towards the housing 20 into a full-lock position. The movement of the first visible or visual surface 28 of the CPA device 10 towards the second visible or visual surface 32 of the housing 20 is monitored or scanned by the machine or electric/electronic scan system 40, as more fully discussed below.

[0039] The machine or electric/electronic scan system 40 scans or detects the movement of the first visible or visual surface 28 on the upper surface 23 of the CPA device 10 relative to the second visible or visual surface 32 on the upper surface 30 of the housing 20. The first visible or visual surface 28 of the CPA device 10 may be referred to as a “Medium No. 1,” while the second visible or visual 32 of the housing 20 may be referred to as a “Medium No. 2.” As illustrated in FIG. 7A, the machine or electric/electronic scan system 40 detects that the first visible or visual surface 28 of the CPA device 10 is separated from the second visible or visual surface 32 of the housing 20, as illustrated and discussed earlier with respect to FIG. 6B. The detected separation between the first visible or visual surface 28 of the CPA device 10 and the second visible or visual surface 32 of the housing 20 is an indication that the CPA device 10 is not fully engaged or absorbed within the housing 20; i.e., the CPA device 10 is in a partial lock position or status relative to the housing 20, and not fully engaged with the housing 20. Although the machine or electric/electronic scan system 40 may have an alternative location relative to the upper surface 30 of the housing 20, the machine or electric/electronic scan system 40 may be located such that its scan transmitting signals 45 and scan receiving signals 50 are directed in a direction that is substantially perpendicular to the first visible or visual surface 28 (Medium No. 1) on an upper surface 23 of the CPA device 10 and the second visible or visual surface 32 (Medium No. 2) on the upper surface 30 of the housing 20, or at an angle based on its “angle of attack” in calculating the locations of the first visible or visual surface 28 of the CPA device 10 and/or the second visible or visual surface 32 of the housing 20 that is being scanned. The varied angle may come into play in tight locations where the scan system 40 may have to scan at a specific angle (e.g., 35°-40° or the like) because the scan system 40 may not have an easy access to the first visible or visual surface 28 (Medium No. 1) on an upper surface 23 of the CPA device 10 and/or the second visible or visual surface 32 (Medium No. 2) on the upper surface 30 of the housing 20.

[0040] In FIG. 7B, the CPA device 10 has been moved or pushed towards the housing 20; and consequently, the first visible or visual surface 28 (Medium No. 1) of the CPA device 10 has joined or abutted against the second visible or visual surface 32 (Medium No. 2) of the housing 20. The joining or abutting of the first visible or visual surface 28 of the CPA device 10 with the second visible or visual surface 32 of the housing 20 is detected by the machine or electric/electronic scan system 40, which indicates that CPA device 10 is fully engaged with the housing 20 or is in full-lock position or status relative to the housing 20.

[0041] Alternatively, in this invention, a predetermined surface of a predetermined or known barcode or QR code can be partially or fully formed on the first visible or visual surface 28 (Medium No. 1) of the CPA device 10, and partially or fully formed on the second visible or visual surface 32 (Medium No. 2) of the housing 20. This structural arrangement or feature is such that when the CPA device 10 is fully engaged or in full-lock position or status relative to the housing 20, the combined first and second visible or visual surfaces 28, 32 (joined Medium No. 1 and Medium No. 2) forms a complete predetermined barcode and/or QR code that is recognizable or distinguishable to a human eye or the electronic eye of the manual or electric/electronic scan system 40. In addition, the human eye or the electronic eye of the manual or electric/electronic scan system 40 should be able to recognize or distinguish that the separation of the first and second visible or visual surfaces 28, 32 (separated Medium No. 1 and Medium No. 2) indicates that the CPA device 10 is not fully engaged with the housing 20 or is in a partial-lock position or status relative to the housing 20.

[0042] In this invention, each of the first visible or visual surface 28 (Medium No. 1) and the second visible or visual surface 32 (Medium No. 2) can partially form a predetermined barcode or QR code that will add up to a fully formed predetermined barcode or QR code when placed adjacent to each other, joined together, or abutting each other. For example, either the first visible or visual surface 28 (Medium No. 1) or the second visible or visual surface 32 (Medium No. 2) can make up substantially 25% of the overall recognized predetermined barcode or QR code, and the other surface or medium will by default need to form the remaining substantially 75% of the overall recognized predetermined barcode or QR code. In other words, if the first visible or visual surface 28 (Medium No. 1) or the second visible or visual surface 32 (Medium No. 2) makes up x % of the barcode, the remaining second visible or visual surface 32 (Medium No. 2) or the remaining first visible or visual surface 28 (Medium No. 1) will by default possess the remaining y % of the barcode, where y %=100%−x % of a fully formed barcode. Similarly, if the first visible or visual surface 28 (Medium No. 1) or the second visible or visual surface 32 (Medium No. 2) makes up x % of the QR code, the remaining second visible or visual surface 32 (Medium No. 2) or the remaining first visible or visual surface 28 (Medium No. 1) will by default possess the remaining y % of the QR code, where y %=100%−x % of a fully formed QR code.

[0043] Also in this invention, the first visible or visual surface 28 (Medium No. 1) of the CPA device 10 and the second visible or visual surface 32 (Medium No. 2) of the housing 20 will be unable to exhibit a complete overall recognizable or detectable predetermined barcode or QR code when the CPA device 10 is in a partial-lock position or status (also referred to as an “unlocked position” or “open position”) relative to the housing 20. The first visible or visual surface 28 (Medium No. 1) of the CPA device 10 and the second visible or visual surface 32 (Medium No. 2) of the housing 20 are required to form a complete overall recognizable or detectable predetermined barcode or QR code when the CPA device 10 is in a full-lock position or status (also referred to as a “locked position” or “closed position”).

[0044] Furthermore, in this invention, the first visible or visual surface 28 (Medium No. 1) of the CPA device 10 and the second visible or visual surface 32 (Medium No. 2) of the housing 20 are distinguishable to a human eye or the machine or electric/electronic scan system 40 with respect to the remaining elements or portions of the CPA device 10 and the housing 20 by contrasting color, UV coating, reflective coating, pad printing, laser etching, engraving, or the like.

[0045] In the embodiment of this invention as illustrated in FIGS. 8A and 8B, each of FIGS. 8A and 8B shows a window scan 90 for use by the machine or electric/electronic scan system 40 for detecting a portion of a predetermined barcode on a Medium No. 1 of the CPA device 10 and another portion of the predetermined barcode on Medium No. 2 on the housing 20 within the window scan 90. In FIG. 8A, it is shown that the Medium No. 1 of the CPA device 10 has not yet been joined or connected together with the Medium No. 2 of the housing 20 with the scan system 40 detecting and recognizing the separately and partially formed barcode within the window scan 90, thereby indicating that the CPA device 10 is in a pre-lock position or status relative to the housing 20. On the other hand, in FIG. 8B, it is shown that the Medium No. 1 of the CPA device 10 has been joined or connected with the Medium No. 2 of the housing 20 with the scan system 40 detecting and recognizing the fully formed barcode within the window scan 90, thereby indicating that the CPA device 10 is in a full-lock position or status relative to the housing 20.

[0046] In another embodiment of this invention as illustrated in FIGS. 8C and 8D, each of FIGS. 8C and 8D shows a window scan 90 for use by the machine or electric/electronic scan system 40 for detecting a portion of a predetermined QR code on a Medium No. 1 of the CPA device 10 and another portion of the predetermined QR code on Medium No. 2 on the housing 20 within the window scan 90. In FIG. 8C, it is shown that the Medium No. 1 of the CPA device 10 has not yet been joined or connected together with the Medium No. 2 of the housing 20 with the scan system 40 detecting and recognizing the separately and partially forayed QR code within the window scan 90, thereby indicating that the CPA device 10 is in a pre-lock position or status relative to the housing 20. On the other hand, in FIG. 8D, it is shown that the Medium No. 1 of the CPA device 10 has been joined or connected with the Medium No. 2 of the housing 20 with the scan system 40 detecting and recognizing the fully formed QR code within the window scan 90, thereby indicating that the CPA device 10 is in a full-lock position or status relative to the housing 20.

[0047] In yet another embodiment of this invention, the machine or electric/electronic scan system 40 determines whether a predetermined percentage of space within a scan window 90 is filled by the Medium No. 1 on an upper surface 73 of the CPA device 70 and/or the Medium No. 2 on an upper surface 85 of the housing 80 for reading or detecting the locking status of the CPA device 70 relative to the housing 80. More particularly, as illustrated in FIGS. 9A and 9B, a retention portion 75 on the upper surface 85 of the housing 80 movably accommodates therein the CPA device 70. As shown in FIG. 9A, the CPA device 70, and therefore the Medium No. 1 thereabove remains at a distance away from the housing 80, and therefore away from the Medium No. 2 thereabove. In this embodiment of this invention, the window scan 90 is focused on the Medium No. 1 of the CPA device 70, as shown in FIG. 9A, and the machine or electric/electronic scan system 40 detects that a predetermined percentage of space 100 within the window scan 90 is not sufficiently or satisfactorily filled by the Medium No. 1 of the CPA device 70 and the Medium No. 2 of the housing 80 with the machine or electric/electronic scan system 40 detecting and recognizing only the predetermined partial barcode on the CPA device 70. Consequently, the machine or electric/electronic scan system 40 detects and records that the CPA device 70 is not fully engaged with the housing 80 or that the CPA device 70 is in a pre-lock position or status relative to the housing 80.

[0048] On the other hand, in FIG. 9B, when the CPA device 70 is moved or pushed towards the housing 80, and therefore, the Medium No. 1 of the CPA device 70 is moved or pushed towards the Medium N0. 2 of the housing 80, in this embodiment of this invention, the window scan 90 remains focused on the Medium No. 1 of the CPA device 70, as shown in FIG. 9B, and the machine or electric/electronic scan system consequently detects that a predetermined percentage of space 100 within the window scan 90 is sufficiently or satisfactorily filled by the Medium No. 1 of the CPA device 70 and the Medium No. 2 of the housing 80. Consequently, the machine or electric/electronic scan system 40 detects and recognizes the fully formed predetermined barcode and records that the CPA device 70 is fully engaged with the housing 80 or that the CPA device 70 is in a full-lock position or status relative to the housing 80.

[0049] In yet another embodiment of this invention, the machine or electric/electronic scan system 40 determines whether a predetermined percentage of space within a scan window 90 is filled by the Medium No. 1 on an upper surface 73 of the CPA device 70 and/or the Medium No. 2 on an upper surface 85 of the housing 80 for reading or detecting the locking status of the CPA device 70 relative to the housing 80. More particularly, as illustrated in FIGS. 9C and 9D, a retention portion 75 on the upper surface 85 of the housing 80 movably accommodates therein the CPA device 70. As shown in FIG. 9C, the CPA device 70, and therefore the Medium No. 1 thereabove remains at a distance away from the housing 80, and therefore away from the Medium No. 2 thereabove. In this embodiment of this invention, the window scan 90 is focused on the Medium No. 1 of the CPA device 70, as shown in FIG. 9C, and the machine or electric/electronic scan system 40 detects that a predetermined percentage of space 100 within the window scan 90 is not sufficiently or satisfactorily filled by the Medium No. 1 of the CPA device 70 and the Medium No. 2 of the housing 80 with the machine or electric/electronic scan system 40 detecting and recognizing only the predetermined partial QR code on the CPA device 70. Consequently, the machine or electric/electronic scan system 40 detects and records that the CPA device 70 is not fully engaged with the housing 80 or that the CPA device 70 is in a pre-lock position or status relative to the housing 80.

[0050] On the other hand, in FIG. 9D, when the CPA device 70 is moved or pushed towards the housing 80, and therefore, the Medium No. 1 of the CPA device 70 is moved or pushed towards the Medium N0. 2 of the housing 80, in this embodiment of this invention, the window scan 90 remains focused on the Medium No. 1 of the CPA device 70, as shown in FIG. 9D, and the machine or electric/electronic scan system consequently detects that a predetermined percentage of space 100 within the window scan 90 is sufficiently or satisfactorily filled by the Medium No. 1 of the CPA device 70 and the Medium No. 2 of the housing 80. Consequently, the machine or electric/electronic scan system 40 detects and recognizes the fully formed predetermined QR code and records that the CPA device 70 is fully engaged with the housing 80 or that the CPA device 70 is in a full-lock position or status relative to the housing 80.

[0051] FIG. 10 is a flowchart of a verification method of this invention for detecting the CPA device's closure relative to the housing 20 using a machine or electric/electronic scan system 40, which uses the reference numbers for the initial embodiment described above for this invention, although this flowchart is similarly applicable in the other embodiments described above for this invention.

[0052] In the method of this invention, as illustrated in the flowchart of FIG. 10, in Step S1, the CPA device 10 is at a pre-lock position or status relative to the housing 20 (i.e., the CPA device 10 is not fully engaged with the housing 20). The electronic visual system 40 (also referred to above as the “machine or electric/electronic scan system 40”), in Step S2, detects that the Medium No. 1 on the CPA device 10 and the Medium No. 2 on the housing 20 are not yet joined or abutted together. In Step S3, the electronic visual system 40 outputs a visual signal that the CPA device 10 is in a pre-lock position or status relative to the housing 20. Thereafter, in Step S4, the CPA device 10 is moved or pushed towards or away from the housing 20 depending on which connector assembly system described above is applicable.

[0053] In this invention, it is preferable that the Medium No. 1 on the CPA device 10 contains thereon a portion of the predetermined barcode or QR code, while the Medium No. 2 on the housing 20 contains thereon another portion of the predetermined barcode or QR code. The portion of the predetermined barcode or QR code on the Medium No. 1 of the CPA device 10 and the another portion of the predetermined barcode or QR code on the Medium No. 2 of the housing 20 form the fully recognizable or detectable predetermined barcode or QR code (scanned and recognized or detected by the electronic visual system 40) when the CPA device 10 is fully engaged with the housing 20 or when the CPA device 10 is in a full-lock position or status with the housing 20.

[0054] In Step S5, the electronic visual system 40 scans the Medium No. 1 on the CPA device 20 and the Medium No. 2 on the housing 20; and consequently, the electronic visual system 40 determines in Step S6 whether the Medium No. 1 on the CPA device 10 and the Medium 2 on the housing 20 are jointed together or abutting each other. A decision is then made that if Step S6 is in the affirmative, it is determined in Step S7 that the CPA device 10 is fully engaged or in full-position or status relative to the housing 20; and the electronic visual system 40 outputs a signal that the CPA device 10 is in full-lock position or status relative to the housing 20 in Step S8.

[0055] On the other hand, if a decision is made that Step S6 is in the negative, it is further determined in Step S9 whether the CPA device 10 and the housing 20 have a spring-loaded connection. If so, and if it is further detected in Step S10 that the Medium No. 1 on the CPA device 10 and the Medium No. 2 on the housing 20 are joined or abut together, then it is determined in Step S11 that the CPA device 10 is in full engagement with the housing 20 or that the CPA device 10 is in full-lock position or status relative to the housing 20. Thereafter, the electronic visual system 30 outputs a visual signal that the CPA device 10 is in full-lock position or status relative to the housing 20.

[0056] If, in Step S9, it is determined that the CPA device 10 and the housing 20 do not have a spring-loaded connection, the method returns to Step S4 whereby the CPA device 10 is moved or pushed towards or away from the housing 20 in Step S4; and the subsequent steps proceed until Step S7 or Step S11 (as discussed above) is reached wherein it is detected that the CPA device 10 is in full-lock position relative to the housing 20, and to Step S8 or Step S12 (as discussed above) wherein the electronic visual system 40 outputs a visual signal that the CPA device 10 is in full-lock position or status relative to the housing 20.

[0057] If, in Step S10, it is determined that the Medium No. 1 of the CPA device 10 and Medium No. 2 of the housing 20 are not yet fully pushed together or not yet abutting together, the method returns to Step S4 whereby the CPA device 10 is moved or pushed towards or away from the housing 20 in Step 4; and the subsequent steps proceed until Step S7 or Step S11 (as discussed above) is reached wherein it is detected that the CPA device 10 is in full-lock position relative to the housing 20, and to Step S8 or Step S12 (as discussed above) wherein the electronic visual system 40 outputs a visual signal that the CPA device 10 is in full-lock position or status relative to the housing 20.

[0058] In the method of this invention, as illustrated in FIG. 10, because the Medium No. 1 of the CPA device 10 and the Medium No. 2 of the housing 20 respectively contain portions of the predetermined barcode or QR code, the portions of the predetermined barcode or QR code are scanned by the electronic visual system 40 in Step S5. The electronic visual system 40 scans and detects whether the predetermined barcode or QR code has been fully formed and scanned as the fully formed predetermined barcode or QR code in Steps S6 and S10. Upon detection that the predetermined barcode or QR code has fully formed or that the predetermined barcode or QR code has been read and detected by the electronic visual system 40, it is then determined that the CPA device 10 is fully engaged within the housing 20 or that the CPA device 10 is in full-lock position or status with the housing 20.

[0059] More particularly, in the embodiment of this invention as illustrated in FIG. 11 is a flowchart of a preferable verification method of this invention for detecting the CPA device's 10 closure relative to the housing 20 using the machine or electric/electronic scan system 40 (or in short, the electronic visual system 40) for reading or detecting a partial or full surface scan of a portion of a predetermined barcode on the CPA device 10 and another portion of the predetermined barcode on the housing 20.

[0060] In the method of this invention, as illustrated in the flowchart of FIG. 11, in Step S1′, the CPA device 10 is at a pre-lock position or status relative to the housing 20 (i.e., the CPA device 10 is not fully engaged with the housing 20). The electronic visual system 40, in Step S2′, detects that the portion of the predetermined barcode on the CPA device 10 and the another portion of the predetermined barcode on the housing 20 are not yet joined or abutted together. In Step S3′, the electronic visual system 40 outputs a visual signal that the CPA device 10 is in a pre-lock position or status relative to the housing 20. Thereafter, in Step S4′, the CPA device 10 is moved or pushed towards or away from the housing 20 depending on which connector assembly system described above is applicable.

[0061] In Step S5′, the electronic visual system 40 scans the portion of the predetermined barcode on the CPA device 20 and the another portion of the predetermined barcode on the housing 20; and consequently, the electronic visual system 40 determines in Step S6′ whether the portion of the predetermined barcode on the CPA device 10 and the another portion of the predetermined barcode on the housing 20 are jointed together or abutting each other. A decision is then made that if Step S6′ is in the affirmative, it is determined in Step S7′ that the CPA device 10 is fully engaged or in full-position or status relative to the housing 20; and the electronic visual system 40 outputs a signal that the CPA device 10 is in full-lock position or status relative to the housing 20 in Step S8′.

[0062] On the other hand, if a decision is made that Step S6′ is in the negative, it is further determined in Step S9′ whether the CPA device 10 and the housing 20 have a spring-loaded connection. If so, and if it is further detected in Step S10′ that the portion of the predetermined barcode on the CPA device 10 and the another portion of the predetermined barcode on the housing 20 are joined or abut together, then it is determined in Step S11′ that the CPA device 10 is in full engagement with the housing 20 or that the CPA device 10 is in full-lock position or status relative to the housing 20. Thereafter, the electronic visual system 30 outputs a visual signal that the CPA device 10 is in full-lock position or status relative to the housing 20.

[0063] If, in Step S9′, it is determined that the CPA device 10 and the housing 20 do not have a spring-loaded connection, the method returns to Step S4′ whereby the CPA device 10 is moved or pushed towards or away from the housing 20 in Step S4′; and the subsequent steps proceed until Step S7′ or Step S11′ (as discussed above) is reached wherein it is detected that the CPA device 10 is in full-lock position relative to the housing 20, and to Step S8′ or Step S12′ (as discussed above) wherein the electronic visual system 40 outputs a visual signal that the CPA device 10 is in full-lock position or status relative to the housing 20.

[0064] If, in Step S10′, it is determined that the portion of the predetermined barcode of the CPA device 10 and the another portion of the predetermined barcode of the housing 20 are not yet fully pushed together or not vet abutting together, the method returns to Step S4′ whereby the CPA device 10 is moved or pushed towards or away from the housing 20 in Step 4′; and the subsequent steps proceed until Step S7′ or Step S11′ (as discussed above) is reached wherein it is detected that the CPA device 10 is in full-lock position relative to the housing 20, and to Step S8′ or Step S12′ (as discussed above) wherein the electronic visual system 40 outputs a visual signal that the CPA device 10 is in full-lock position or status relative to the housing 20.

[0065] More particularly, in another embodiment of this invention of this invention as illustrated in FIG. 12 is a flowchart of a preferable verification method of this invention for detecting the CPA device's 10 closure relative to the housing 20 using the machine or electric/electronic scan system 40 (or in short, the electronic visual system 40) for reading or detecting a partial or full surface scan of a portion of a predetermined QR code on the CPA device 10 and another portion of the predetermined QR code on the housing 20.

[0066] In the method of this invention, as illustrated in the flowchart of FIG. 12, in Step S1″, the CPA device 10 is at a pre-lock position or status relative to the housing 20 (i.e., the CPA device 10 is not fully engaged with the housing 20). The electronic visual system 40, in Step S2″, detects that the portion of the predetermined QR code on the CPA device 10 and the another portion of the predetermined QR code on the housing 20 are not yet joined or abutted together. In Step S3″, the electronic visual system 40 outputs a visual signal that the CPA device 10 is in a pre-lock position or status relative to the housing 20. Thereafter, in Step S4″, the CPA device 10 is moved or pushed towards or away from the housing 20 depending on which connector assembly system described above is applicable.

[0067] In Step S5″, the electronic visual system 40 scans the portion of the predetermined QR code on the CPA device 20 and the another portion of the predetermined QR code on the housing 20; and consequently, the electronic visual system 40 determines in Step S6″ whether the portion of the predetermined QR code on the CPA device 10 and the another portion of the predetermined QR code on the housing 20 are jointed together or abutting each other. A decision is then made that if Step S6″ is in the affirmative, it is determined in Step S7″ that the CPA device 10 is fully engaged or in full-position or status relative to the housing 20; and the electronic visual system 40 outputs a signal that the CPA device 10 is in full-lock position or status relative to the housing 20 in Step S8″.

[0068] On the other hand, if a decision is made that Step S6″ is in the negative, it is further determined in Step S9″ whether the CPA device 10 and the housing 20 have a spring-loaded connection. If so, and if it is further detected in Step S10″ that the portion of the predetermined QR code on the CPA device 10 and the another portion of the predetermined QR code on the housing 20 are joined or abut together, then it is determined in Step S11″ that the CPA device 10 is in full engagement with the housing 20 or that the CPA device 10 is in full-lock position or status relative to the housing 20. Thereafter, the electronic visual system 30 outputs a visual signal that the CPA device 10 is in full-lock position or status relative to the housing 20.

[0069] If, in Step S9″, it is determined that the CPA device 10 and the housing 20 do not have a spring-loaded connection, the method returns to Step S4″ whereby the CPA device 10 is moved or pushed towards or away from the housing 20 in Step S4″; and the subsequent steps proceed until Step S7″ or Step S11″ (as discussed above) is reached wherein it is detected that the CPA device 10 is in full-lock position relative to the housing 20, and to Step S8″ or Step S12″ (as discussed above) wherein the electronic visual system 40 outputs a visual signal that the CPA device 10 is in full-lock position or status relative to the housing 20.

[0070] If, in Step S10″, it is determined that the portion of the predetermined QR code of the CPA device 10 and the another portion of the predetermined QR code of the housing 20 are not yet fully pushed together or not yet abutting together, the method returns to Step S4″ whereby the CPA device 10 is moved or pushed towards or away from the housing 20 in Step 4″; and the subsequent steps proceed until Step S7″ or Step S11″ (as discussed above) is reached wherein it is detected that the CPA device 10 is in full-lock position relative to the housing 20, and to Step S8″ or Step S12″ (as discussed above) wherein the electronic visual system 40 outputs a visual signal that the CPA device 10 is in full-lock position or status relative to the housing 20.

[0071] The present invention is not limited to the above-described embodiments; and various modifications in design, structural arrangement or the like may be used without departing from the scope or equivalents of the present invention.
