## Background
BACKGROUND OF THE INVENTION
Field of the Invention
This disclosure relates to a device configured to be coupled with or to be integrated into a marker pen or other writing implement, such that the marker pen or writing implement is adapted for mounting on a glassboard, whiteboard or the like to conveniently locate the marker pen thereon.
Description of the Related Art
Blackboards and whiteboards have been in use for a long time. These devices provide a convenient space for instructors or attendees at meetings to record their thoughts for a group using chalk and pens. Whiteboard, and more recently glassboards, have gained popularity as more convenient and cleaner to use than blackboards. One common problem with whiteboards is a lack of systematic way to keep track of markers pens used with them. A common technique for keeping markers pens with the board includes using a tray formed in or mounted to the frame of the whiteboard.
Glassboards, which are gaining in popularity form part of, or are mounted to a wall surface. A layer of glass is the structure upon which the user writes. These devices improve on whiteboards in being more durable, and being more aesthetically pleasing with a sleek, modern look. While glassboards can be equipped with a tray for marker pens and other accessories, such components are utilitarian and take away from the aesthetics of the installation.
Pens and markers have been combined with attachment devices to help secure them to structures. Most pens have a clip for securing the pen to paper or a shirt pocket. Lanyards can be attached to pen body or caps to make the pen wearable. Magnets have been used in place of clips or to secure ends of a pen to an object. While these techniques have been used even in connection with whiteboards, the magnet arrangements have been insufficient or inconvenient for use with glassboards, whiteboards, and the like.
SUMMARY OF THE INVENTION
In one embodiment, an adaptor is provided for securing a writing implement to a glassboard, a whiteboard, or the like. The adaptor includes a magnet housing, a magnet, and a coupler. The magnet housing has a magnet compartment disposed adjacent to a side periphery thereof. The magnet is disposed in the magnet compartment. The magnet provides a magnetic field away from the side periphery of the magnet housing. The coupler is configured for attaching an end of the magnet housing to an end of a writing implement. When the coupler is attached to a writing implement, the magnetic field enables the adaptor to magnetically support the writing implement from a side position.
In another embodiment, an apparatus is provided for connecting a writing implement to a glassboard, whiteboard or the like. The apparatus has a magnet housing adapted to be connected to a writing implement. The magnet housing has a side surface with an opening formed therein and a recess extending from the opening into the housing. The magnet is disposed in the recess and provides a magnetic field in a direction away from the side surface of the magnet housing. For example, one or more poles can be provided at one or more openings from which the recess extends. The magnet enables a side periphery of a writing implement coupled with the apparatus to magnetically couple with the glassboard, whiteboard or the like in a predetermined orientation regardless of the initial orientation of approach of the writing implement.
In another embodiment, a writing implement is provided that includes a distal end, a proximal end, a housing and a magnet coupled with the housing. The housing has an elongate hollow structure that has a side surface surrounding a cavity. A writing medium is coupled with the housing, e.g., is disposed within the cavity, and exposed at the distal end. The magnetic coupled with the housing and having a pole located along the side surface of the housing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
While the present description sets forth specific details of various embodiments, it will be appreciated that the description is illustrative only and should not be construed in any way as limiting. Furthermore, various applications of such embodiments and modifications thereto, which may occur to those who are skilled in the art, are also encompassed by the general concepts described herein. Each and every feature described herein, and each and every combination of two or more of such features, is included within the scope of the present invention provided that the features included in such a combination are not mutually inconsistent.
FIG. 1 shows a marker assembly 100 that is able to be conveniently secured to a glassboard, whiteboard or the like (sometimes referred to collectively as “boards”). The marker assembly 100 includes a dry erase marker 104 and an adaptor 108 that enables the assembly 100 to automatically connect to a ferrous structure without regard to initial angle of approach, as will be discussed in greater detail below, and in some cases to self-orient writing-tip down. The assembly 100 has particularly advantageous application to glassboards and other multilayer structures where a ferrous layer is disposed behind a non-ferrous layer of significant depth.
The writing implement assembly 100 includes a dry erase marker 104 but can include any writing implement that might be of use on or with a board. The marker 104 can include a cylindrical housing extending between a proximal and distal end of the writing implement and an ink cartridge or similar structure partly disposed in the housing and partly exposed at the distal end of the writing implement. The ink structure leaves visible marks upon contact with a writing surface of the board. The marker can include a cap, as illustrated, for covering the exposed portion of the writing tip.
FIGS. 1 and 2 show that the adapter 108 can be configured as a separate or separable component form the marker 104. FIG. 2 also shows that one technique for connecting the adaptor 108 to the marker 104 involves moving a distal projection 112 into a recess 116 of the marker 104 along the direction of the arrow 120. FIG. 2 shows that in one embodiment, the adaptor 108 has a recess 130 that is able to be coupled with a distal projection 126 of the cap (or other distal portion) of the marker 104. In one embodiment, the adaptor 108 includes the projection 112 and the recess 130, but in some embodiments one of these features is omitted. The separability of the adaptor 108 from the marker 104 enables the adaptor 108 to be re-used which is useful because components of the adaptor 108 are expected to have a much longer useful life than those of the marker 104.
FIGS. 3 and 4 show further details of one embodiment of the adaptor 108, which includes a core assembly 140 and a sleeve 144 disposed about the core assembly 140. The core assembly 140 includes a magnet housing 148 (See FIG. 7) and a magnet 152. The magnet 152 is received in the magnet housing 148 and can be secured therein by an adhesive or other structure or devices, such as mechanical locking features, a close fit such as interference fit or the like.
The sleeve 144 can take any suitable form, but preferably is sized to be disposed over the magnet housing 148. The sleeve 144 can have a cylindrical structure with a distal or top shoulder 160 and a proximal or bottom shoulder 164 (see FIG. 3). The cylindrical structure can have an outside cylindrical surface 168 and an inside cylindrical surface (not shown). The outside cylindrical surface 168 preferably comprises a friction layer that enhances the engagement of the adaptor 108 with a board, as discussed further below. The inside cylindrical surface of the sleeve 144 is sized to receive the magnet housing 148 without excessive stretch but in a manner that prevents relative rotation of the magnet housing and the sleeve. The top shoulder 160 has an annular structure that extends oriented inward form the cylindrical surface 168 to an inner periphery 172. The shoulder 160 has a width that extends from the outer cylindrical surface 168 to the inner periphery 172. This distance preferably is sufficient to cover a distal shoulder of the magnet housing 148. The inner periphery 172 of the shoulder 160 is preferably sized to permit the distal projection 112 of the adaptor 108 to extend therethrough.
The bottom shoulder 164 has an annular structure that extends oriented inward form the cylindrical surface 168 to an inner periphery 176. The shoulder 164 has a width that is the distance from the outer cylindrical surface 168 to the inner periphery 176. The width of the shoulder 168 is selected to provide access to the recess 130 if provided.
FIGS. 4-7 shows features of the core assembly 140 and its components. The magnet housing 148 includes a rigid body that can be molded from a suitable polymer, such as Acrylonitrile-Butadiene-Styrene (ABS) plastic. Other materials and processes can be used. In the molded part there can be a cylindrical structure 190 that extends from a proximal or bottom end of the housing 148 to a distal facing shoulder 194. The distal facing shoulder 194 can be perforated with one or a plurality of openings 198 extending proximally of the shoulder. The projection 112 can be disposed on and project distally of the distal facing shoulder 194. The projection 112 can be a hollow unitary body extension of a portion of the distal facing shoulder 194.
FIGS. 5-7 show that in some embodiments an opening 210 is provided along a first side surface 214 and a second opening 218 is provided along a second side surface 222 of the cylindrical structure 190. FIG. 6 shows that a recess 226 can extend from the first side opening 210 into the magnet housing 148. FIG. 6 shows that the recess 226 can extend from the second side opening 218 into the magnet housing 148. In some embodiment, the recess 226 extends from the first side opening 210 to the second side opening 218 such that the recess 226 extends entirely across the housing 148. The recess 226 can be located in an intermediate portion of the housing 148. For example, the recess 226 can be located between a distal portion including the projection 112 and a proximal portion including the recess 130.
In one embodiment, the intermediate portion of the magnet housing 148 also includes a plurality of walls 230 disposed on opposite sides of a central zone of the recess 226. The walls 230 connect the distal and proximal portions of the magnet housing 148 to each other. The magnet housing 148 can have one or more channels 234 disposed between the walls 230 and the nearest outer wall of the cylindrical structure 190. The channels 234 can have an annular shape and can be disposed about the walls 230 in one embodiment. The channels 234 preferably are connected to the openings 198 disposed on the distally facing shoulder 194.
FIG. 6 shows the position of the magnet 152 in the magnet housing 148 in dashed lines for better illustrating of other components. FIG. 10 shows further details of the magnet 152. In particular, the magnet includes a first pole 250 and a second pole 254 in one embodiment. The first pole 250 can include an arcuate structure. FIGS. 7 and 10 collectively show that the first pole 250 can have a partial cylindrical surface. The first pole 250 can be formed on a cylindrical surface having a constant radius and can have a height corresponding to the height of the magnet 152. The magnet 152 is preferably elongate, such that the poles 250, 254 are spaced apart by a distance corresponding to the length of the magnet 152. The configuration of the magnet 152 is preferably selected to provide sufficient strength to hold a writing implement on a board and may be further configured to automatically orient the adaptor 108 and the assembly 100 in more than one degree of freedom regardless of the initial approach of the assembly 100 to the board. The strength of the magnet 152 can be provided by any suitable approach, for example by providing a length or spacing the poles 250, 254 apart by a sufficient distance. In one embodiment, the length of the magnet 152 is about 3⁄4 inch. The magnet can be between about 1⁄8 inch and about 2 inches in length. The thickness of the magnet can also be selected as needed to provide appropriate strength for the application in question.
In certain embodiments the magnet 152 is configured such that a sufficiently strong magnetic field is provided between the poles 250, 254 to support the adaptor 108 and an assembly 100 on a board. In certain cases, the magnet 152 can have a BHmax between 25 MGOe and 60 MGOe. In certain cases, the magnet 152 can have an externally measurable magnetic field between about 500 Gauss and about 1500 Gauss or between about 500 Gauss and about 3000 Gauss or between about 500 Gauss and about 10000 Gauss. In certain cases, the magnet 152 can have an externally measurable magnetic field between about 3000 Gauss and about 10000 Gauss. In certain embodiments, the magnet 152 can have a BHmax between about 2 MGOe and about 15 MGOe or between about 2 and about 25 MGOe. In certain embodiments, the magnet 152 can have a BHmax between about 25 MGOe and about 60 MGOe and an externally measurable magnetic field between about 3000 Gauss and about 10000 Gauss.
FIG. 10 illustrates a magnetic field 256 generated by the magnet 152. Just a few flux lines are shown to illustrate the field 256. Two flux lines are shown continuously extending between the poles 250, 254. Three additional flux lines are shown as emanating from the poles but the intervening portions of these flux lines have been omitted to simplify the drawing. But one skilled in the art will know that each line of the flux lines extends entirely between pole 250 and pole 254. In this case, the magnet 152 is configured such that the flux 256 is focused in the plane of the magnet, meaning that field lines can be represented as emanating from the poles 250, 254 and being disposed generally between the planes of the top and bottom surfaces of the magnet 152. This configuration focuses the attractive force of the magnet 152 to the two poles 250, 254. This arrangement is useful in automatically orienting the adaptor 108 with respect to ferrous structures of a board, as discussed below.
The magnet 152 can be secured in the magnet housing 148 in any suitable technique. FIG. 7 illustrates one approach in which the magnet 152 is advanced into the first opening 210. One of the poles 254, 250 can be advanced into the opening 210 first. Then the length of the magnet 152 can be advanced though the opening 210 until the initially inserted pole is disposed at the opening 218. An approach for securing the magnet 152 in the recess 226 involve placing adhesive to bridge between the magnet housing 148 and the magnet 152. During assembly, e.g., after or before the magnet 152 is placed in the recess 226, an adhesive can be directed through the openings 198 into the channels 234 to bond to the magnet 152 and the magnet housing 148. The bonding to the magnet 152 can be at the locations where the channels 234 meet the recess 226. The bonding to the magnet housing 148 can along the walls of the channels 234.
The width of the distal shoulder 160 of the sleeve 144 preferably is large enough to cover the openings 198 such that after the adhesive has been dispensed into the channels 234 the openings 198 can be covered. In other embodiments, the sleeve 144 is omitted and the openings 198 maybe filled such that the adhesive is flush with the distal facing shoulder 194 of the magnet housing 148.
FIG. 5 shows that in certain embodiments, a flush configuration is provided between the pole 250 and the side surface 214 and the pole 254 and the side surface 222. The flush configuration is provided in part by forming the poles 250, 254 with the same radius of curvature as that of the side surfaces 214, 222. For example, if the magnet housing 148 comprises a cylindrical body, the cylindrical body and the magnet poles 250, 254 can have the same radius of curvature. Also, if both poles 250, 254 are exposed the magnet 152 can have a length such that it extends all the way across the magnet housing 148 from the first side surface 214 to the second side surface 222. The flush configuration provides several advantages. First, the magnet length can be increased or maximized, which allows the strength of the magnet to be increased or maximized. Stronger magnets can be used in more applications, such as in glassboards as discussed below. Second, the flush mounting allows the strongest part of the magnetic field to be closest to the surface of the adaptor 108. Because field strength decreases over distance, providing the magnet 152 recessed in or completely encapsulated in the magnet housing 148 reduces the ability of the adaptor 108 to secure to remote structures. By preventing the magnet 152 from protruding from the magnet housing 148, the adaptor 108 is more streamlined not presenting any protuberances to the user that could scratch a board or otherwise be disruptive to use. Where both poles 250, 254 are disposed in a flush manner at a surface of the magnet housing 148 the adaptor 108 is provided with a plurality of preferred engagement positions, which is useful for automatically aligning the assembly 100 with a board as discussed below.
FIGS. 10-12 illustrate some of the advantageous modes of use of the adaptor 108 and the assembly 100 in which it can be included. As noted above, FIG. 10 shows the magnetic field lines that emit from the magnet 152. This field is stronger than typical refrigerator magnets. The magnet 152 may be formed from a rare earth material, such as neodymium (NdFeB) and equivalent variants. FIG. 11 shows one type of board 300 for which the adaptor 108 is particularly well suited. The board 300 has multiple layers, including an exposed layer 304 adapted for being written on by the marker 104 and ferrous layer 308. An intervening layer 312 is shown, and may include an adhesive or in fact more than one layer for other purposes. In some cases, the ferrous layer 308 and the exposed layer are immediately adjacent to each other. In some boards 300, the exposed layer is a layer of glass having a thickness of about one-eight inch or more, e.g., up to about one-half inch or more. In some applications, the board 300 the exposed layer is a white coating layer applied directly to the ferrous layer 308.
In one application the assembly 100 can be coupled with a whiteboard, which can have a ferrous metal, e.g., steel, with a thickness between about 0.003 inch and about 0.25 inch. The ferrous metal may be coated but otherwise direct contact can be provided between the assembly 100 and the ferrous metal. Any type of magnetic material having between about 5 MGOe and about 25 MGOe and measurable surface gauss between about 1 and about 3000 can be used for the magnet 152. In another application, the assembly 100 can be coupled with a glassboard having a non-ferrous material with thickness between 1⁄8 inch to 1⁄2 inch with ferrous backing with a thickness of about 0.003 inch to about 0.25 inch. In the glassboard applications, a magnetic material between about 25 MGOe and about 60 MGOe or higher, and measurable surface gauss between about 3000 and about 10000 Gauss or higher can be used.
FIGS. 11 and 12 also show the magnetic field 256 in the context of the board 300. The magnetic field 320 extends in a direction away from the side surface of the magnet housing 148 and can extend into the board 300 in use. The field 256 is illustrated for simplicity by one dashed line from each pole in these figures, though as noted above the magnetic field generated by the magnet 152 is strong and would correspond to a highly dense arrangement of flux lines. The field 256 is also shown in the inset image, as extending from the poles of the magnet 152 through one or more layers to the ferrous layer 308. In the inset image the magnet 152 is shown alone for ease of illustration, but would be coupled with the adaptor 108 and the marker pen 104 or other writing implement in use.
The adaptor 108 enables a side periphery of the marker pen 104 or other writing implement coupled therewith to couple with the board 300 in a low profile manner, e.g., with the longitudinal axis of assembly 100 or marker pen 104 to be aligned with, e.g., parallel to the plane of the exposed surface 304. This arrangement advantageously minimizes the distance that the marker pen 104 extends out from the surface 304 in the space in which the board 300 is located. By minimizing this distance the pen 104 and assembly 100 are out of the way when not in use.
The adaptor 108 advantageously enables the assembly 100 to magnetically couple with the board 300 in a predetermined orientation regardless of the initial orientation of approach of the writing implement. For example, FIG. 11 shows a dashed line outline of the assembly 100 placed against the board 300 in an orientation where the writing end is up. That is, a cap of the marker 104 is disposed at an elevation above the adaptor 108. In this example, the magnet 152 is already oriented in a direction providing the strongest field into the board across the exposed layer 304 to the ferrous layer 308. That is, the long axis of the magnet is disposed perpendicular to the board 300. The adaptor 108 is configured to permit the writing end of the marker 104 to rotate down as indicated by the arrow 332 to the writing-tip down position shown in solid lines in connection with the assembly 100. For example, the magnet 152 can be made strong enough to securely couple the assembly 100 with the board 300 but not so strong that the pen is not permitted to swing down to the writing-tip down position, as indicated by the arrow 332. The rotation indicated by arrow 332 is about an axis perpendicular to the board 300 and extending generally through the intermediate portion of the housing 148.
FIG. 12 shows another scenario where a side periphery of the marker 104 or other writing implement coupled with the adaptor 108 to magnetically couple with the board 300 in a predetermined orientation regardless of the initial orientation of approach of the writing implement. In particular, the assembly 100 is oriented so that the longitudinal axis of the magnet 152 (e.g., the axis extending between the poles 250, 254) is not perpendicular to, e.g., is parallel to the plane of the exposed surface 304 or the ferrous layer 308. The magnet 152 is most strongly magnetically coupled with the board 300 when the long axis of the magnet 152 is perpendicular to the ferrous layer 308 of the board 300. The magnet 152 is made strong enough that it will cause the assembly 100 to self-rotate to align to the strongest magnetic coupling orientation. In the figure the arrow 334 illustrates rotation of the assembly 100 from the weak engagement position (in dash) to the strong engagement position (in solid lines). This rotation is due to the configuration of the magnet 152, including the strength and arrangement of the magnet 152 in the housing 148. Aspects of the arrangement of the magnet 152 that facilitate this include the exposed, flush oriented poles 250, 254 and the elongate magnet structure. The rotation indicated by arrow 334 causes the marker 304 to turn about its longitudinal axis so that the long axis of the magnet 152 changes its orientation from parallel (in dash) to perpendicular to the board (in solid). Of course, the rotations 330 and 334 can both happen depending on the initial orientation of approach of the assembly 100 to the board 300.
Another advantage of arrangements with a plurality of, e.g., two, three, four, five, or six or more, exposed poles is the amount of rotation required according to the arrow 334 is reduced. In the two pole arrangement of FIG. 5, the adaptor 108 and assembly 100 can orient to the correct position according to the arrow 334 by rotating less than 180 degrees, e.g., less than 90 degrees about the longitudinal axis of the assembly 100. This allows the assembly 100 to quickly orient to a position in which the marker pen 104 can be supported on the board 300. As noted above, the rotational orientation can be coordinated with an elevational orientation to position the marker pen 104 in an wiriting-tip down position.
Although the description of the assembly 100 includes the advantageous separability of the adaptor 108 from the marker 104, it is possible to integrate the adaptor into the marker 104 in another assembly. In the integrated form, the magnet 152 can be disposed in the same housing or cylinder in which the ink of the marker 104 is disposed. Such arrangement has the advantage of not requiring end-user assembly. Also, there is no possibility of the adaptor 108 being lost because it is already part of the marker 104. When configured as separable, the adaptor 108 can be reused when the ink in the marker 104 is consumed.
FIGS. 8 and 9 illustrate further embodiments of an adaptor 308. The adaptor 308 can have any feature disclosed in connection with the adaptor 108, except as described differently below. The adaptor 308 has a core assembly 312 that includes a magnet housing 316 and a magnet 320. The magnet 320 is disposed in a passage in the housing 316. The passage can extend from an opening 324 disposed on a side surface 328 of the housing 316.
The side surface 328 can include an annular recess 332 disposed therein. The annular recess 332 provides a stepped side profile in the housing 316. The annular recess 332 can be disposed between a first ledge 336 and a second ledge 340. The first ledge 336 can be located adjacent to an end projection 338 of the adapter 308. The second ledge 340 can be located between the first projection 336 and an end of the adaptor 308 opposite the projection 338. In one embodiment, the passage for the magnet 320 extends between openings on opposites sides of the annular recess 332. The magnet 320 can be configured to be flush with the surface of the annular recess 332 so that it is disposed radially inwardly of a cylinder defined by the radial extent of the ledges.
The adaptor 308 is thus configured to receive a sleeve 352 that is at least partially recessed in the magnet housing 316 of the core assembly 312. The sleeve 352 can take any suitable form, but preferably is flexible and has a first edge 356, a second edge 360 and a cylindrical portion 364 extending therebetween. The cylindrical portion 364 comprises an inside surface 368 and an outside surface 372. The adaptor 308 is configured such that the sleeve 352 can be placed over the magnet housing 316 such that the inside surface 368 is disposed on the side surface 328. FIG. 8 shows that when the sleeve 352 is so positioned, the first edge 356 preferably is disposed adjacent to the first ledge 336 and the second edge 360 preferably is disposed adjacent to the second ledge 340. The cylindrical portion 364 preferably is received in the annular recess located between the first ledge 336 and the second ledge 340.
Although the ledges 336, 340 can completely surround the side surface 328, in some embodiments, the ledges 336 and/or 340 can be configured as projections with a circumferential length that is less than the circumference of the side surface 328. It is also possible to provide that one of the ledges 336, 340 extends entirely around the magnet housing 316 and that one of the ledges 336, 340 comprises one or more short projections disposed only partly around the housing 316. The ledge(s) 336 and/or 340 provide the advantage of retaining the band 352 on the housing 316. That is an axial load on the band 352 will be resisted by the ledges 336, 340 such that the band does not inadvertently separate from the housing 316. This is important in assuring that the magnet 320 is retained in the housing 316.
The adaptor 308 is advantageous in providing for ease of assembly. In particular, the sleeve 352 can be easily applied to the magnet housing 316. For example, the sleeve 352 has a cylindrical form so that there are no radially inwardly projecting ends to be stretched over the ends of the magnet housing 316. The sleeve 352 is also easier to remove and replace as needed. For example, if the sleeve 352 became discolored or damaged it could easily and quickly be replaced. In some cases, the sleeve 352 may be in good condition, but it may be desirable to change the color. For example, the color of the sleeve 352 can be changed to match the color of the ink in the writing implement with which the adaptor 308 may be coupled. Also, removing the sleeve 352 provides access to the magnet 320 such that the magnet can be replaced. For example, in some applications a weaker magnet may be replaced for a stronger magnet. In other applications a stronger magnet may be replaced for a weaker magnet. Also, the sleeve 352 can optionally be configured with an information portion 370. The information portion 370 can include a promotional message, a company log, inspirational message, advertisement, or other markings. The informational portion 370 can be configured as an imprint or can include printing. Because the sleeve 352 is configured for ease of coupling with the magnet housing 316, theses markings can be easily exchanged for different uses or customers.
Also, even though it is very flexible and adaptable, the cylindrical sleeve 352 has the advantage of being very low cost both because it is low cost to produce and because it is low cost to assemble with the magnet housing 316. Although the embodiments herein have wide application it is anticipated that the price per-unit should be kept as low as possible to increase the marketability of the apparatuses.
The annular recess 332 also enables the sleeve 352 to be flush-mounted or only minimally radially protruding from the side surface 328 of the housing 316. This provides improved aesthetics because a continuous or smooth side profiler results.
Although certain embodiments are described herein as adaptors, a variety of integrated assemblies can also be provided within the scope of this application. That is, the structures of the adaptors can be integrated into a portion of a writing implement in certain applications.
As used herein, the relative terms “proximal” and “distal” shall be defined from the perspective of the tip of the writing implement. Thus, distal refers the direction of the tip of the writing implement, while proximal refers to the direction of the end of the writing implement opposite to the tip.
Conditional language, such as “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements, and/or steps. Thus, such conditional language is not generally intended to imply that features, elements, and/or steps are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without user input or prompting, whether these features, elements, and/or steps are included or are to be performed in any particular embodiment.
The terms “approximately,” “about,” and “substantially” as used herein represent an amount close to the stated amount that still performs a desired function or achieves a desired result. For example, the terms “approximately”, “about”, and “substantially” may refer to an amount that is within less than 10% of, within less than 5% of, within less than 1% of, within less than 0.1% of, and within less than 0.01% of the stated amount. As another example, in certain embodiments, the terms “generally parallel” and “substantially parallel” refer to a value, amount, or characteristic that departs from exactly parallel by less than or equal to 15 degrees, 10 degrees, 5 degrees, 3 degrees, 1 degree, 0.1 degree, or otherwise.
