The present invention relates to a snare wire attachment structure for attaching a snare wire to a snare drum using a snare frame and a snare drum.
A snare drum includes a cylindrical shell, a pair of drum heads, a snare wire, and a strainer. The drum heads, together with corresponding hoops, are mounted on the upper and lower opening ends of the shell. The snare wire is attached to the snare drum in a manner contacting the back-surface head. The strainer is fixed to the outer peripheral surface of the shell at such a position as to facilitate manipulation by the player.
The player manipulates the strainer to switch the position of the snare wire selectively to ON position and OFF position. The snare wire contacts the back-surface head when at ON position and is spaced from the back-surface head when at OFF position. To play the snare drum, the player switches the position of the snare wire to ON position and, in this state, strikes the striking-surface head, which is the upper one of the drum heads. This adds the vibration sound of the snare wire to the vibration sound of the striking-surface head and that of the back-surface head, thus producing resonance of the characteristic sound of the snare drum.
The snare wire is configured by a snare portion configured by multiple wires and a pair of end plates. The end plates are located on the opposite ends of the snare portion. Depending on the manner in which the snare portion contacts the back-surface head, the snare wire may be classified as an inside-surface hitting snare wire or a full-surface hitting snare wire. The full length of the inside-surface hitting snare wire is smaller than the diameter of the back-surface head. Therefore, the inside-surface hitting snare wire is attached to the snare drum with the snare portion and the opposite end plates both held in contact with the back-surface head. In contrast, the full length of the full-surface hitting snare wire is greater than the diameter of the back-surface head. Therefore, the full-surface hitting snare wire is attached to the snare drum with the opposite end plates exposed outward with respect to the outer peripheral edge of the back-surface head and with only the snare portion held in contact with the back-surface head.
The snare wire is attached to the snare drum typically using a belt or string. Specifically, the belt or string is hooked to the opposite end plates of the snare wire. Using the belt or string, one of the end sections of the snare wire is coupled to a holder located in a lower section of the strainer. The other end section of the snare wire is coupled, at a position opposite to the strainer, to a holder of a holding tool located on the outer peripheral surface of the shell. The player, while playing the snare drum, manipulates the strainer to pull and raise the snare wire to ON position by means of the belt or string. In this manner, tensile force is applied to the snare wire and, correspondingly, the position of the snare wire is switched from OFF position to ON position.
However, in the above-described snare wire attachment structure, the tensile force of the snare wire and the amount by which the snare portion contacts the back-surface head cannot be adjusted separately. To solve this problem, a snare wire attachment structure that uses a snare frame to attach a snare wire to a snare drum has been proposed. For example, U.S. Pat. Nos. 3,113,481, 8,193,435, 3,981,220, and 4,138,920, as well as Japanese Laid-Open Utility Model Publication No. 60-163499 and U.S. Pat. Nos. 7,223,910 and 7,741,550, disclose snare wire attachment structures using snare frames.
Each of the snare frames disclosed in U.S. Pat. Nos. 3,113,481, 8,193,435, 3,981,220, and 4,138,920 is attached to a snare drum using a string with a snare portion and opposite end plates of a snare wire held in contact with the back-surface head. When the string is pulled intensely to increase the amount by which the snare portion contacts the back-surface head, the snare wire attachment structure disclosed in each of the aforementioned documents causes the end plates of the snare wire to bite into the surface of the back-surface head. The end plates of the snare wire thus hamper vibration of the back-surface head, obstructing resonance of the vibration sound of the striking-surface head and that of the back-surface head.
Each of the snare frames disclosed in Japanese Laid-Open Utility Model Publication No. 60-163499 and U.S. Pat. Nos. 7,223,910 and 7,741,550 is attached to a snare drum using a link component instead of a belt or a string. Two link members made of rigid material such as metal are employed. The snare wire attachment structure disclosed in each of the aforementioned documents holds the opposite longitudinal end sections of the snare frame by means of the link members. However, fixing the snare frame in a manner integrated with the snare drum together with the link members, as in this case, promotes the hampering of the vibration of the snare frame and that of the snare wire. As a result, compared to the attachment structure using a belt or a string, the snare wire attachment structure using a link component decreases resonance of the vibration sound of the snare wire. As has been described, the conventional snare frames have structural problems that hamper resonance of the characteristic sound of a snare drum.

An embodiment of a snare wire attachment structure according to the present invention will now be described with reference to
As shown in
A drum head is mounted on the upper opening end of the shell 11, together with an upper hoop 21, and thus functions as a striking-surface head 12a. Another drum head is mounted on the lower opening end of the shell 11, together with a lower hoop 22, and thus functions as a back-surface head 12b.
The snare drum 10 includes eight first tension bolts 23 and eight first lugs 24. The first tension bolts 23 fix the upper hoop 21 and the striking-surface head 12a to the upper opening end of the shell 11. The first tension bolts 23 are fastened to the corresponding first lugs 24. The snare drum 10 also includes eight second tension bolts 25 and eight second lugs 26. The second tension bolts 25 fix the lower hoop 22 and the back-surface head 12b to the lower opening end of the shell 11. The second tension bolts 25 are fastened to the corresponding second lugs 26. The first and second lugs 24, 26 are each fixed to the outer peripheral surface of the shell 11.
Each of the first lugs 24 and the corresponding one of the second lugs 26 are arranged in a manner forming a pair in the up-down direction. The first and second lugs 24, 26 are spaced apart at equal angles about the axis of the shell 11. The first tension bolts 23 are inserted in the threaded holes of the corresponding first lugs 24 and selectively fastened and loosened to change the amount by which the upper hoop 21 is engaged with the shell 11. In this manner, the tensile force of the striking-surface head 12a is changed. The second tension bolts 25 are inserted in the threaded holes of the corresponding second lugs 26 and selectively fastened and loosened to change the amount by which the lower hoop 22 is engaged with the shell 11. In this manner, the tensile force of the back-surface head 12b is changed. By manipulating the first and second tension bolts 23, 25 in these manners, the sound of the snare drum 10 is adjusted.
With reference to
In the state in which the snare wires 13, 14 are attached to the snare drum 10 by means of the snare frame 15, as illustrated in
With reference to
As shown in
With reference to
Each frame body portion 51 has hook shafts 57 and stoppers 58 at the positions at which the corresponding strings 16 are hooked. The stoppers 58 are located one by one at an intermediate position between the first end section 51a and the middle section of the frame body portion 51 and an intermediate position between the second end section 51b and the middle section of the frame body portion 51. The hook shafts 57 are each located at a position closer to the end section of the frame body portion 51 than the corresponding stopper 58. Each hook shaft 57 has a threaded shaft that is inserted through the frame body portion 51. A nut 60 is fastened to the threaded shaft from the inner side, thus fixing the hook shaft 57 to the outer side of the frame body portion 51. Each of the stoppers 58 has a basal end section through which a bolt 61 is inserted. A nut 26 is fastened to the bolt 61 from the inner side, thus fixing the stopper 58 to the outer side of the frame body portion 51 in a pivotable manner.
A first attachment-detachment portion 59a is configured by the hook shaft 57 and stopper 58 located in correspondence with the first end section 51a of each frame body portion 51. A second attachment-detachment portion 59b is configured by the hook shaft 57 and stopper 58 located in correspondence with the second end section 51b of the frame body portion 51. The position of the first attachment-detachment portion 59a is symmetrical with the position of the second attachment-detachment portion 59b with respect to the longitudinal middle of the frame body portion 51. Therefore, the first and second attachment-detachment portions 59a, 59b are arranged at positions spaced equally from the pipe 56, which is located between the middle sections of the frame body portions 51.
As illustrated in
As shown in
Three accommodation spaces 65a are defined in the end section body 65. Each of the accommodation spaces 65a accommodates the corresponding one of the end plate fixing portions 66, together with an E-ring. Three communication holes 65b are formed in a side wall of the end section body 65 and communicate with the corresponding accommodation spaces 65a. The accommodation spaces 65a and the communication holes 65b are aligned and spaced apart at equal intervals in the longitudinal direction of the end section body 65.
With reference to
The end plate 13b and the end plate 14b have a through hole 13c and a through hole 14c, respectively. When the end plate 13b, 14b is hooked to the hook portion 66a, the flange 66b passes through the through hole 13c, 14c. The diameter of a head portion 67a of each screw 67, which is fastened to the corresponding threaded hole 66c, is greater than the width of the through hole 13c, 14c. Therefore, the head portion 67a of the screw 67, which is fastened to the threaded hole 66c, stops separation of the end plate 13b, 14b of the snare wire 13, 14 from the hook portion 66a of the end plate fixing portion 66.
In the state in which the snare wires 13, 14 are attached to the snare drum 10 by means of the snare frame 15, each of the end plate fixing portions 66 is disposed in the corresponding one of the accommodation spaces 65a of the end section body 65 with the threaded hole 66c facing downward and the bolt hole 66d facing outward. In this state, the bolt 68 is fastened to the bolt hole 66d of the end plate fixing portion 66 through the communication hole 65b from the outer side of the end section body 65. By changing the amount by which the bolt 68 is fastened to the bolt hole 66d, each end plate fixing portion 66 is allowed to slide in the corresponding accommodation space 65a along axis C2 of the bolt 68. That is, by manipulating the respective bolts 68 separately from one another, the corresponding end plate fixing portions 66 are allowed to slide independently of one another in the first frame end section 52.
As shown in
As illustrated in
In the state in which the snare wires 13, 14 are attached to the snare drum 10 by means of the snare frame 15, the slider 74 is disposed in the accommodation space 75a of the end section body 75 with threaded holes 74c facing downward and a bolt hole 74d facing outward. The bolt 78 is fastened to the bolt hole 74d of the slider 74 through the communication hole 75b from the outer side of the end section body 75. By changing the amount by which the bolt 78 is fastened to the bolt hole 74d, the slider 74 is allowed to slide in the accommodation space 75a along axis C3 of the bolt 78. That is, by manipulating the bolt 78, the end plate fixing portions 76 are allowed to slide integrally in the second frame end section 53.
As shown in
With reference to
In the snare frame 15, the first and second frame end sections 52, 53 are arranged outward with respect to the outer peripheral edge of the back-surface head 12b in the radial direction of the shell 11. The first frame end section 52 is arranged below the holder 17a of the strainer 17. As viewed in the axial direction of the shell 11, the first frame end section 52 is disposed at the position coinciding with the holder 17a. The second frame end section 53 is arranged below the holder 18a of the holding tool 18. As viewed in the axial direction of the shell 11, the second frame end section 53 is disposed at the position coinciding with the holder 18a.
The strings 16 are each coupled to the snare frame 15 by means of the corresponding hook shaft 57 and stopper 58 at a position inward with respect to the outer peripheral edge of the back-surface head 12b. Specifically, in the vicinities of the first end sections 51a of the frame body portions 51, the first attachment-detachment portions 59a couple the corresponding strings 16 to the snare frame 15 at the positions intermediate between the first end sections 51a and the middle sections of the frame body portions 51. In the vicinities of the second end sections 51b of the frame body portions 51, the second attachment-detachment portions 59b couple the corresponding strings 16 to the snare frame 15 at the positions intermediate between the second end sections 51b and the middle sections of the frame body portions 51. Each of the strings 16 is bent by the outer peripheral edge of the back-surface head 12b and the outer frame of the lower hoop 22 and, in this state, couples the snare frame 15 to the snare drum 10.
Next, the operation of the attachment structure of the snare wires 13, 14, as well as the attachment procedure of the snare wires 13, 14, will be described with reference to
To attach the snare wires 13, 14 to the snare drum 10 using the snare frame 15, as illustrated in
After switching the position of each snare wire 13, 14 from OFF position to ON position, the effective lengths of the strings 16 are changed at the side corresponding to the corresponding holders 17a, 18a to adjust the position of the snare frame 15 in the up-down direction. The effective length of each string 16 represents such a length of the string 16 that the string 16 functions as a coupling member in the state mounted on the holder 17a and the first attachment-detachment portion 59a or the holder 18a and the second attachment-detachment portion 59b. In other words, the effective length of the string 16 represents the apparent length of the string 16 that couples the holder 17a to the first attachment-detachment portion 59a or the holder 18a to the second attachment-detachment portion 59b when the snare wires 13, 14 are located at ON positions.
After switching the positions of the snare wires 13, 14 to ON positions, the manipulating portions 17c, 18c are manipulated to change the positions of the holders 17a, 18a in the up-down direction such that the position of the snare frame 15 is further adjusted in the up-down direction. In this manner, with the snare wires 13, 14 arranged at ON positions, by adjusting the effective lengths of the respective strings 16 or changing the positions of the respective holders 17a, 18a, the state of contact between the snare portion 13a, 14a of each snare wire 13, 14 and the back-surface head 12b is precisely adjusted.
To detach the snare frame 15 from the snare drum 10, all of the stoppers 58 are pivoted until the distal end sections of the stoppers 58 face upward, as represented by the long dashed double-short dashed lines in
The operation of the attachment structure of the snare wires 13, 14 will hereafter be described.
The strings 16, which are used to couple the snare frame 15 to the snare drum 10, are made of flexible material. The strings 16 thus provide flexibility to the portions that couple the snare frame 15 to the holders 17a, 18a. This configuration does not hamper the vibration of the snare frame 15, unlike the configuration using link components made of metal as coupling members. As a result, the vibration of each of the snare wires 13, 14 is not hampered and resonance of the vibration sound of each snare wire 13, 14 is allowed.
The first and second frame end sections 52, 53 are both arranged outward with respect to the outer peripheral edge of the back-surface head 12b in the radial direction of the shell 11. Such arrangement causes only the snare portions 13a, 14a of the snare wires 13, 14 to contact the back-surface head 12b. This makes it unlikely that the end plates 13b, 14b of the snare wires 13, 14 will bite into the surface of the back-surface head 12b even when the strings 16 are pulled intensely to increase the amounts by which the snare portions 13a, 14a contact the back-surface head 12b. The end plates 13b, 14b thus do not hamper the vibration of the back-surface head 12b, allowing resonance of the vibration sound of the striking-surface head 12a and the vibration sound of the back-surface head 12b. This improves resonance of the characteristic sound of the snare drum 10.
The present embodiment has the advantages described below.
(1) Each of the string 16 serving as a coupling member is made of flexible material and does not hamper the vibration of the snare frame 15. The vibration of each snare wire 13, 14 is thus not hampered, which allows resonance of the vibration sounds of the snare wires 13, 14. Also, since the first and second frame end sections 52, 53 are each disposed outward with respect to the outer peripheral edge of the back-surface head 12b, the end plates 13b, 14b of the snare wires 13, 14 are unlikely to bite into the surface of the back-surface head 12b. The end plates 13b 14b thus do not hamper the vibration of the back-surface head 12b, which allows resonance of the vibration sound of the striking-surface head 12a and that of the back-surface head 12b.
(2) The first frame end section 52 is disposed below the holder 17a of the strainer 17 at the position coinciding with the holder 17a as viewed in the axial direction of the shell 11. The second frame end section 53 is arranged below the holder 18a of the holding tool 18 at the position coinciding with the holder 18a as viewed in the axial direction of the shell 11. In this configuration, the first and second frame end sections 52, 53 are disposed immediately below the corresponding holders 17a, 18a. Each of the first and second frame end sections 52, 53 is thus spaced outward from the outer peripheral edge of the back-surface head 12b. This allows the readily vibrating portions of the snare portions 13a, 14a to contact the surface of the back-surface head 12b. The snare wires 13, 14 are thus allowed to vibrate effectively, thus further improving resonance of the vibration sounds of the snare wires 13, 14. Also, in this configuration, the snare frame 15 projects outward only to a limited extent in the radial direction of the shell 11 and thus does not obstruct the playing by the player when the player plays the snare drum 10.
(3) The strings 16 are coupled to the snare frame 15 by the corresponding hook shafts 57 and stoppers 58 at the positions inward with respect to the outer peripheral edge of the back-surface head 12b. In this configuration, the strings 16 are bent by the outer peripheral edge of the back-surface head 12b and, in this state, couple the snare frame 15 to the snare drum 10. As a result, the snare frame 15 is coupled to the snare drum 10 with a certain level of tensile force acting on the strings 16. Therefore, even if the snare drum 10 is played with the striking-surface head 12a inclined, the contact between the snare portion 13a, 14a of each snare wire 13, 14 and the back-surface head 12b is maintained in a desirable state. This further improves resonance of the vibration sounds of the snare wires 13, 14.
In the present embodiment, the four strings 16 are employed to couple the snare frame 15 to the snare drum 10. The snare frame 15 is configured such that the effective lengths of the strings 16, which correspond to the four corners of the snare frame 15, are adjustable independently. In this case, by changing the effective lengths of the respective strings 16, the state of contact between the snare portion 13a, 14a of each snare wire 13, 14 and the back-surface head 12b is adjusted precisely. This facilitates uniform contact between the snare portions 13a, 14a of the snare wires 13, 14 and the back-surface head 12b, regardless of the angle at which the snare drum 10 is installed.
(4) Each string 16 is selectively attached to and detached from either the corresponding the holder 17a, 18a of the strainer 17 or the holding tool 18 or the corresponding first or second attachment-detachment portion 59a, 59b of the snare frame 15. In this configuration, simply by detaching the strings 16 from either the snare frame 15 or the snare drum 10, the snare frame 15 is detached from the snare drum 10. In this case, the snare frame 15 is detached from the snare drum 10 with the snare wires 13, 14 fixed to the snare frame 15, without changing the tensile force of each snare wire 13, 14.
If the effective lengths of the strings 16 are adjusted to ensure uniform contact between the snare portions 13a, 14a and the back-surface head 12b, the snare frame 15 can be detached from the snare drum 10 with the strings 16 remaining attached to either the snare frame 15 or the snare drum 10, without changing the adjusted effective lengths of the strings 16. Therefore, in this configuration, the tensile force of each snare wire 13, 14 and the effective length of each string 16 are maintained in the adjusted states even after the snare drum 10 is detached from the snare frame 15. This facilitates reproduction of the sound of the snare drum 10 that has been produced by the most recent play.
The strings 16 are each attachable-detachable from the snare frame 15 and the snare drum 10. Therefore, unlike the conventional configurations, it is unnecessary to pull or loosen each snare wire by means of the corresponding string every time the snare wire is detached. The snare frame 15 is thus easily detached from the snare drum 10. This facilitates replacement of each drum head and decreases the load on the snare portion 13a, 14a of each snare wire 13, 14.
(5) The position of the first attachment-detachment portion 59a is symmetrical with the position of the second attachment-detachment portion 59b about the longitudinal middle of each frame body portion 51. In this configuration, the snare wires 13, 14 may be detached from the snare drum 10 and then the snare frame 15 may be attached to the snare drum 10 with the posture of the snare frame 15 reversed with respect to its posture before detachment from the snare drum 10. This allows reproduction of the sound of the snare drum 10 that has been produced by the most recent play.
(6) The end plate fixing portions 66 of the first frame end section 52 are arranged such that each end plate fixing portion 66 forms a pair with the corresponding end plate fixing portion 76 of the second frame end section 53. This allows attachment of different types of snare wires 13, 14, such as straight wires and coil wires, to the snare frame 15. Using the different types of snare wires 13, 14, resonance of the characteristic sound of the snare drum 10 is further improved.
(7) The end plate fixing portions 66 are slidable in the first frame end section 52 independently of one another. In this configuration, the tensile force of each snare wire 13, 14 is adjusted separately by manipulating the corresponding one of the three bolts 68 separately. Also, the amount by which the snare portion 13a, 14a of each snare wire 13, 14 contacts the back-surface head 12b is adjusted precisely.
The end plate fixing portions 76 are slidable integrally in the second frame end section 53. This configuration allows the simultaneous pulling and loosening of the snare wires 13, 14, thus facilitating the applying and releasing of tensile force with respect to the snare wires 13, 14. The attachment-detachment of the snare wires 13, 14 with respect to the snare frame 15 is thus facilitated.
(8) Each end plate fixing portion 66 of the first frame end section 52 has the hook portion 66a and the flange 66b. The end plate 13b, 14b of each snare wire 13, 14 is hooked to the corresponding hook portion 66a. The flanges 66b are located below the corresponding hook portions 66a. The end plate fixing portions 76 of the second frame end section 53 are configured identically with the end plate fixing portions 66 of the first frame end section 52. In this configuration, when the end plates 13b, 14b of the snare wires 13, 14 are hooked to the corresponding end plate fixing portions 66, 76, the end plates 13b, 14b are supported from below by the flanges 66b, 76b of the end plate fixing portions 66, 76. As a result, when a certain level of tensile force acts on the snare wires 13, 14, the opposite ends of each snare wire 13, 14 are supported by the snare frame 15 such that the snare wire 13, 14 does not separate from the snare frame 15. This makes it unnecessary to fix the end plates 13b, 14b of the snare wires 13, 14 to the snare frame 15 using screws every time the snare wires 13, 14 are replaced when the snare drum 10 is tuned.
If, for example, the tensile force of each snare wire 13, 14 is adjusted while the snare drum 10 is being played, there may be a case in which the snare wire 13, 14 is released from the tensile force. Even in this case, the end plates 13b, 14b of the snare wires 13, 14 are supported from below by the head portions 67a, 77a of the corresponding screws 67, 77, which are fastened to the threaded holes 66c, 74c of the end plate fixing portions 66, 76. The snare wires 13, 14 are thus stopped from separating from the snare frame 15 even after the snare wires 13, 14 are released from the tensile force.
Also, in this configuration, the end plates 13b, 14b are held pivotably without being fixed to the end plate fixing portions 66, 67 using the screws 67, 77. Each end plate 13b, 14b is thus allowed to pivot at the corresponding one of the opposite ends of the snare portion 13a, 14a and move to such a position that uniform tensile force acts on the snare portion 13a, 14a of the snare wire 13, 14.
(9) Four of the second tension bolts 25 are disposed in the vicinities of the opposite end sections of the snare frame 15 and the leg supports 28 are each mounted on the corresponding one of the four second tension bolts 25. In this configuration, when the snare wires 13, 14 are attached to the snare drum 10 using the snare frame 15 and the snare drum 10 is placed on the floor surface, the leg supports 28 maintain the snare frame 15 higher than the floor surface such that the snare frame 15 is in a load-free state.
The present embodiment may be modified in the forms described below.
Although the strings 16 are employed as the coupling members in the present embodiment, the coupling members may be belts. Also in this case, the belts are made of flexible high-strength plastic such as nylon.
In the present embodiment, the first frame end section 52 may be arranged below the holder 17a of the strainer 17 at a position between the outer peripheral edge of the back-surface head 12b and the holder 17a. Similarly, the second frame end section 53 may be arranged below the holder 18a of the holding tool 18 at a position between the outer peripheral edge of the back-surface head 12b and the holder 18a.
In the present embodiment, the end sections of the snare frame 15 may be coupled to the holder 17a of the strainer 17 and the holder 18a of the holding tool 18 using the strings 16, each at a position outward with respect to the outer peripheral edge of the back-surface head 12b.
In the present embodiment, the snare frame 15 is detached from the snare drum 10 by detaching the strings 16 from the first and second attachment-detachment portions 59a, 59b with the strings 16 held by the corresponding holders 17a, 18a. That is, the effective lengths of the respective strings 16 are adjusted at the sides corresponding to the holders 17a, 18a and the strings 16 are detached from the snare frame 15 without changing the adjusted effective lengths of the strings 16. However, the embodiment is not restricted to this. For example, the snare frame 15 may be detached from the snare drum 10 by detaching the strings 16 from the holders 17a, 18a with the strings 16 attached to the snare frame 15. In this case, the effective lengths of the respective strings 16 are adjusted at the side corresponding to the snare frame 15 and the strings 16 are detached from the holders 17a, 18a without changing the adjusted effective lengths of the strings 16.
In the present embodiment, the four strings 16 are used to couple the snare frame 15 to the snare drum 10 and the effective lengths of the strings 16 are separately adjustable. However, the embodiment is not restricted to this. For example, two strings 16 may be fixed to the opposite ends of the snare frame 15 and the effective lengths of the strings 16 may be adjusted separately. That is, any number of strings 16 may be employed as long as the effective lengths of the strings 16 are adjustable independently for each of the four corners of the snare frame 15.
In the present embodiment, the same type of snare wires may be attached to the snare frame 15 or, alternatively, one or more snare wires may be attached to the snare frame 15. If two or more snare wires are attached to the snare frame 15, the snare wires may all be different types of snare wires from one another.
In the present embodiment, the configuration for allowing the end plate fixing portions 66 to be slidable may be omitted from the first frame end section 52. Also, the configuration for allowing the slider 74 to be slidable may be omitted from the second frame end section 53.
Various changes in form and details may be made to the examples above without departing from the spirit and scope of the claims and their equivalents. The examples are for the sake of description only, and not for purposes of limitation. Descriptions of features in each example are to be considered as being applicable to similar features or aspects in other examples. Suitable results may be achieved if sequences are performed in a different order, and/or if components in a described system, architecture, device, or circuit are combined differently, and/or replaced or supplemented by other components or their equivalents. The scope of the disclosure is not defined by the detailed description, but by the claims and their equivalents. All variations within the scope of the claims and their equivalents are included in the disclosure.
