Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to an athletic apparatus
generally, and more specifically to a device and method for
athletic performance evaluation.
[0002] Most sports are based on the development of specialized
athletic abilities such as response time, coordination and
strength. As such, an athletes training is designed to develop the
athletes maximum potential. However, it is extremely difficult to
quantify or objectively measure an athlete's overall ability. As a
result of this difficulty, an athlete's performance in sports, for
example football, is usually determined through a coach's
observation or by competing against other athletes. However, these
observations and trials have heretofore been mostly subjective.
Objective measurement of athletic ability is particularly
beneficial for training since this provides the athlete with a
ability to identify those abilities and skills which require the
most attention, and to measure the performance increase thereof. In
addition, it would be highly beneficial for a coach or other
training professional to evaluate a player's ability through a
standardized system utilizing objectively obtained data. In this
manner, an athlete could be evaluated for performance in a strictly
objective manner that has heretofore been unknown. The use of a
device which objectively measures an athlete's performance or skill
can greatly assist not only athletes in reaching their potential,
but also the trainers in evaluating and assessing an athletes
ability.
[0003] Accordingly, a need exists for an athletic apparatus that
can, among other things, objectively measure an athlete's
performance, thereby allowing the athlete to be evaluated for
performance in a strictly objective manner. Therefore, an athletic
apparatus that solves the aforementioned disadvantages and having
the aforementioned advantages is desired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0023] The best mode for caring out the invention is presented in
terms of the preferred embodiment, wherein similar referenced
characters designate corresponding features throughout the several
figures of the drawings.
[0024] For purposes of description herein, the terms "upper",
"lower", "right", "left", "rear", "front", "vertical",
"horizontal", and derivatives thereof, shall relate to the
invention as oriented in FIG. 1. However, it is to be understood
that the invention may assume various alternative orientations,
except where expressly specified to the contrary. It is also to be
understood that the specific devices and processes illustrated in
the attached drawings and described in the following specification
are exemplary embodiments of the inventive concepts defined in the
appended claims. Hence, specific dimensions and other physical
characteristics relating to the embodiments disclosed herein are
not to be considered as limiting, unless the claims expressly state
otherwise.
[0025] Reference will now be made in detail to the present
preferred embodiments of the invention, examples of which are
illustrated in the accompanying drawings. Wherever possible, these
same referenced numerals will be used throughout the drawings to
refer to the same or like parts. The dimensions illustrated in the
drawings (if provided) are included for purposes of example only
and are not intended to limit the scope of the present invention.
Additionally, particular details in the drawings which are
illustrated in hidden or dashed lines are to be considered as
forming no part of the present invention.
[0026] As used herein, the term athlete is meant to refer to anyone
utilizing the athletic evaluation device, and the term is not meant
to be limited to a particular type of individual or to a particular
sport or activity. However, for brevity, we will discuss herein the
inventive athletic device as it works with and relates to the
evaluation of a football player. Of course, this is not meant to be
limiting in any manner and this device may be used to evaluate
numerous other types of athletes, and may be used to evaluate
numerous other activities.
[0027] A common training apparatus that is used to currently
measure a football players ability is the blocking sled. These
apparatuses come in many variations and can be either stationary or
movable, and numerous routines can be practiced on these sleds.
Typically, these devices include a force receiving area which is
usually called a pad, blocking pad, or dummy, and two common
routines practiced on these devices are the runner block and the
pass block. With the runner block, the routine starts by having the
subject move forward, toward the pad, and the athlete asserts as
much force to the pad with their shoulder, forearms, or hands, as
the subject is able to, while driving the pad with the subjects
legs for a specified period of time. With the pass block, the
routine starts by having the subject take a position with their
back towards the pad, and the subject then moves backwards, until
the pad is contacted.
[0028] At present, relatively few systems can objectively measure
the ability of an athlete, or measure the performance increase or
decrease therein. In addition, it would be highly beneficial for a
coach or other training professional to evaluate an athlete's
ability through a standardized system utilizing objectively
obtained data. In this manner, an athlete could be evaluated for
performance in a strictly objective manner that has heretofore been
unknown. The use of a device which objectively measures an
athlete's performance or skill can greatly assist not only athletes
in reaching their potential, but also the trainers in evaluating
and assessing an athletes ability.
[0029] The disadvantages and drawbacks of the prior art are
overcome through the athletic training apparatus 2 of the present
invention (FIGS. 1-4) which includes a generally horizontal base 10
which is adapted to be positioned on a ground surface. The training
apparatus also includes a first sensor 31 that is operably
connected to base 10, whereby when an athlete is positioned on a
first portion 12 of base 10, first sensor 31 measures the weight of
the athlete. A force receiving area 50 is also included as part of
training apparatus 2. The force receiving area 50 is typically
disposed above base 10 in proximity to one end 16 thereof. A second
sensor 51 is operably connected to force receiving area 50, and
when the athlete exerts a force on force receiving area 50, second
sensor 51 measures the force exerted by the athlete. In addition, a
third sensor 72 may also be operably connected to base 10, wherein
the second and third sensors, 51 and 72, respectively, are adapted
to measure a time it takes the athlete to move a fixed distance on
base 10. Although the training apparatus may be developed to simply
measure the aforementioned weight, force, and time values,
apparatus 2 may also be operably connected to and communicate with
a computer 91, wherein first sensor 31 communicates the weight
measurement, second sensor 51 communicates the force measurement,
and at least third sensor 72 communicates the time measurement. As
such, computer 91 can calculate a performance factor F utilizing
each of the results from the first, second, and third sensors in
the equation (weight/time)*force=F/100, wherein the weight is
determined from the first sensor, the force is determined from the
second sensor, and the time is determined from at least the third
sensor.
[0030] In one preferred embodiment, athletic training apparatus 2
may take on the form of a typical tackling, blocking or leg drive
apparatus, have a generally rectangular shape, and be fabricated
from a rigid material such as steel into a generally unitary
configuration. However, the shape of athletic training apparatus 2
may vary according to specific requirements and need not be
rectangular in configuration. Further, although one preferred
embodiment of athletic training apparatus 2 is fabricated from a
rigid material, other materials, pliable or rigid, may be used. In
addition, although this particular embodiment of athletic training
apparatus 2 is fabricated into a generally unitary configuration
which is portable, multiple piece configurations may also be
utilized and further, apparatus 2 may be stationary.
[0031] As best illustrated by FIGS. 1-2, the athletic training
apparatus 2 of the present invention includes a generally
horizontal base 10 that is adapted to be positioned on a ground
surface. Base 10 includes a first portion 12 proximate to a first
end 14, and a second portion 24 proximate a second end 16. In one
preferred embodiment, base 10 can be further subdivide into an
upper portion 18 for supporting an athlete thereon, and a lower
portion 19 for supporting the upper portion as well as supporting
apparatus 2 on the ground surface. Upper and lower surfaces 18 and
19, will typically be separated by one or more sensors 31,
described in more detail below. As illustrated by FIG. 3, in one
preferred embodiment this separation is accomplished by having
lower portion 19 resting on the ground surface, having first sensor
31 resting on lower portion 19, and having upper portion 18 resting
on sensor 31. This sandwiched style assembly maintains alignment by
having pins 22 of lower portion 19 closely received and in
alignment with apertures 23 of upper portion 18. Again, base 10 may
be subdivided into more than one portion. As illustrated, one
preferred embodiment includes a first portion 12 and second portion
24, wherein second portion 24 may have one or more additional
sensors 32 if required. Base 10 also includes pad base 40 for
receiving thereon pad support 41 which support pad 50 in proximity
to second end 16 base 10.
[0032] The specific configuration and features of base 10 may vary
according to the requirements of the end user. In one preferred
embodiment, base 10 is generally rectangular in shape and is
fabricated into a multi-zoned configuration, wherein each portion
12 and 24 has a width of from about 3 feet to about 5 feet, and a
length of from about 3 feet to about 12 feet. However, the shape
and size of athletic training apparatus 2 may vary, need not be
rectangular in configuration, and may be shorter or longer as the
requirements dictate. Further, although one preferred embodiment of
base 10 is fabricated into a multi-zone configuration, a single
zone may be utilized. Still further yet, first portion 12, second
portion 24, and pad base 40 may all be made to be either integral
with each other or separate therefrom. In one preferred embodiment,
base 10 and base 40 are fabricated to be assembled into a single or
unitary configuration.
[0033] As best illustrated by FIG. 3, first sensor 31 is operably
connected to base 10. As described above, one such connection may
be accomplished by having first sensor 31 rest on lower portion 19,
and having upper portion 18 rest on sensor 31 in a floating or
sandwich style assembly which is kept in alignment by pins 22 and
apertures 23. First sensor 31 may be any type or style of a sensor
and may measure various attributes. However, in one preferred
embodiment first sensor 31 is used to measure the weight of the
athlete when the athlete is positioned on first portion 12 of base
10. For example, when an athlete is disposed on and in their
initial blocking stance on first portion 12, sensor 31 can measure
the weight of the athlete. Of course, sensor 31 may also be
disposed separate from base 10. For example, a separate scale may
be used to measure the weight of the athlete, wherein the athlete's
weight is recorded on sensor 31 either before or after the athlete
performs the blocking maneuvers on base 10.
[0034] First sensor 31 may be any type or style of a sensor that is
capable of measuring, among other things, weight. However, in one
preferred embodiment sensor 31 is a load cell including a centrally
located sensor 31 having a generally X-shaped body or frame 34. The
X-shaped frame of sensor 31 allows sensor 31 to more accurately
read the athletes weight, when positioned on first portion 12, even
when the athlete is not positioned centrally over sensor 31. Of
course this can be accomplished in various others ways, as for
example by using multiple sensors, and is not meant to be
limiting.
[0035] A force receiving area such as a pad, blocking pad, or dummy
50 is positioned in close proximity to one end of base 10,
typically second end 16. In one preferred embodiment pad 50 is
rigidly affixed to pad base 40, and base 40 is rigidly affixed to
base 10 proximate second end 16. This configuration allows little
to no relative movement between base 10 and pad 50. Of course, pad
50 may be attached directly to second end 16 if so desired.
Naturally, if the requirements dictate, pad 50 may be operably
connected to or positioned near base 10 to allow movement
therebetween.
[0036] Pad 50 may be any type or size receiving area. In one
preferred embodiment, pad 50 is generally rectangular, from about 4
inches to about 8 inches wide, from about 1 foot to about 3 feet in
height, and from about 2 inches to about 8 inches in thickness.
However, the shape and size of pad 50 may vary, and the
configuration need not be rectangular, and may be shorter or longer
as the requirements dictate.
[0037] A generally rigid plate 42 connects pad 50 to an arm 44. For
example, plate 42 may be fabricated from plate steel having a
thickness of from about 0.250 inches to about 0.500 inches.
Further, arm 44 rigidly connects plate 42 at a first end 45, and a
second 46 is adjacently disposed to second sensor 51. In one
preferred embodiment, arm 44 is a tube having a diameter of from
about 1.0 inch to about 8.0 inches, and is closely received within
an outer tube 47. For example, a clearance of about 0.005 inches
may be utilized. Although arm 44 and outer tube 47 may be
fabricated for sliding engagement if so required, as discussed
above, they are generally not slidingly engaged and outer tube 47
is closely received and mounted within arm 44 in a static manner.
Further, in this preferred embodiment, plate 42 and sensor 51 may
be disposed from about 1 foot to about 3 feet from each other.
Again however, the shape, size, and distance of plate 42, arm 44
and outer tube 47 may vary according to specific requirements and
this is in no way meant to be limiting.
[0038] As described above, second sensor 51 is operably connected
to pad 50, through plate 42, arm 44, and outer tube 47. In this
exemplary configuration, when the athlete exerts a force against
pad 50, for example when the athlete "blocks" pad 50 as is
typically done on a standard blocking machine, the force is
transferred to second sensor 51 to be measured. Sensor 51 can also
be used for an additional time measurements. For example, the
initial time of impact may be recorded, or the duration of the
impact may be recorded. Further yet, weight sensor 31 (or 32 if so
provided) can also be utilized to measure the force exerted by the
athletes legs on base 10 during the interval when the athlete is
applying force to pad 50. These additional measurements may also be
used in the performance analysis.
[0039] Second sensor 51 may be any type or style of sensor and may
measure various attributes. However, in the preferred embodiment
second sensor 51 is fabricated to measure the force exerted against
pad 50 as well as the initial time of impact. For example, when an
athlete blocks pad 50, sensor 51 may record the initial time of the
exerted force, the amount of exerted force, and the duration of the
exerted force. In one preferred embodiment, sensor 31 is a load
cell adapted to measure these various values. Obviously, the
specific characteristics of sensor 51 may vary according to
specific requirements and this is in no way meant to be
limiting.
[0040] A third sensor 72 may also be included with athletic
training apparatus 2. Sensor 72 may be used, for example, to
measure the time it takes an athlete to traverse a fixed distance
on base 10. Although one or more sensors 72 may be utilized, the
preferred embodiment utilizes sensor 72 in conjunction with sensor
51 to measure the time the athlete takes to traverse the fixed
distance. This is accomplished by utilizing sensor 72 to measure
the athlete's movement, at a fixed location proximate first end 14,
while sensor 51 measures the initial impact on pad 50. Since pad 50
is disposed a fixed, known, distance from sensor 72, since the time
when the athlete passes sensor 72 is known, and since the time when
the athlete first makes contact with pad 50 is known, the time it
takes the athlete to traverse this fixed distance is known. As
such, this time can be used in objectively analyzing the athletes
performance and the athletes speed, among other things, can know be
calculated. For example, when the athlete initiates movement
towards pad 50 at a point D0, sensor 72 may be tripped to indicate
an initial time T0. As the athlete travels a specified distance D1
to pad 50 and makes contact with pad 50, sensor 51 may record this
time as T1. Hence, the time T it took the athlete to traverse the
fixed distance D, wherein D=D1-D0, is known from T=T1-T0.
Additionally, a sensor 71 may also be included which will determine
if the athlete is in the correct position before the blocking or
other routine is carried out. For example, an indicator such as a
sound can be played to indicate when the athlete is in the correct
position before the athlete is signaled to start the routine.
Therefore, by utilizing sensors 31, 51, 71, and 72 the initial
positioning of the athlete, the movement of the athlete, the time
the athlete took to traverse a specified distance, and the total
time the athlete took to reach pad 50 can be objectively
determined. As such, the weight of the athlete, the speed of the
athlete, the acceleration of the athlete, the various times of the
athlete, and/or the force exerted by the athlete can be calculated,
recorded and objectively analyzed.
[0041] Sensors 71 and 72 may be any type or style of a sensor that
are capable of measuring, among other things, movement and/or time.
In one preferred embodiment sensors 71 and 72 may be photoelectric
eyes, cameras, or light curtains. Of course, numerous other sensors
may be utilized, and this is in no way meant to be limiting.
Additionally, sensors 71 and 72 may also be movable along base 10
for maximum flexibility.
[0042] Although the training apparatus may be designed to merely
measure the aforementioned weight, force, and time values, one
preferred embodiment of athletic training apparatus 2 is operably
connected to, communicates with, and records to a computer 91. As
such, first sensor 31 communicates the weight measurement, second
sensor 51 communicates at least the force measurement, and third
sensor 72, if provided, will communicate a time measurement to
computer 91 for recordation, display, further calculation, and/or
analysis. For example, computer 91 may utilize these various
measurements to calculate the weight, speed, and exerted force of
the athlete, and further, computer 91 may display the results
numerically or graphically on monitor 94. After receiving the
measurements from sensors 31, 51, and 72, computer 91 may also
utilize the measurements to calculate a performance factor F in the
equation (weight/time)*force=F/100, wherein the weight is
determined from the first sensor 31, the force is determined from
the second sensor 51, and the time is determined from either the
third sensor 72, or the third sensor 72 in conjunction with second
sensor 51, as described previously. Therefore, by utilizing only a
few sensors and a single machine, the weight, speed, acceleration,
time, and the force exerted by the athlete can be objectively
calculated, recorded and objectively analyzed. Further, a single
numerical value or performance factor F can be created from these
various measurements, allowing the trainer a single number or
factor 160 (see FIG. 5), whereby the player may be objectively
measured and compared. Additionally, performance measure 160 can be
analyzed over time to determine if the player's performance remains
the same, increases, or decreases. Further yet, with extensive use
and analysis with machine 2, a player's career ability could be
indicated by initial use of the machine. For example, a player's
performance factor 160 would be calculated after initial use of the
machine and performance factor 160 would be compared to other
athlete's known or previously recorded performance factors. This
would allow the trainer a simple tool that could be used, in whole
or in part, to decide which players will make the team, get
scholarships, etc.
[0043] Athletic apparatus 2 is used by having the athlete weighed
on a weight sensor or scale 31. Sensor 31 may be either separate
from machine 2 (for example a separate scale) or, in a more
preferred embodiment, part of apparatus 2. In this embodiment, the
unit works by having the athlete position himself on first portion
12 of base 10, wherein first portion 12 will have weight sensor 31
disposed therein so as to automatically read the athletes weight
when the athlete is disposed thereon in a first position (i.e. the
initial blocking stance). As the athlete assumes this starting
position or stance, sensor 71 will sense whether or not the athlete
is in the correct position and may indicate this, for example, by
an audible sound. The athlete will either self-initiate the
blocking operation, or be instructed to do so by an external
source. As the athlete moves from the initial starting position to
some intermediate position, third sensor 72 will be triggered as
the athlete passes the sensor, whereby the sensor will be used to
start an internal or external clock (for example time=T0).
Additionally, first sensor 31 will be able to record this initial
start of the athlete because weight sensor 31 will record a spike;
the spike being caused by the athlete's initial acceleration
against base 10. Therefore, sensor 31 may alternatively, or in
addition to sensor 51, be used to calculate the initial time T0.
The player will then continue to accelerate and move towards pad 50
until initial contact with pad 50 is made. At this point, sensor 72
may be adapted to measure this initial contact and time (time=T1)
or alternatively, second sensor 51 may be used for calculating this
second time measurement, in addition to the exerted force. For
example, when the athlete initiates movement towards pad 50 at some
point D0 (typically the athlete initial stance), sensor 72 may be
tripped to indicate an initial time T0. As the athlete travels a
specified distance D1 (for example the distance from D0 to pad 50)
and makes contact with pad 50, sensor 51 may record this time as
T1. Hence, the time T it takes the athlete to traverse the fixed
distance D, wherein D=D1-D0, is known from T=T1-T0. Further, since
the distance D and the time T are known, additional factors may be
calculated, for example, for speed and acceleration of the athlete.
However, sensor 51 will also be used to determine and record the
force exerted by the athlete on pad 50, and the time duration of
the exerted force. Typically, the player will exert a force against
pad 50 with his upper body or shoulder such that when the player
"blocks" pad 50, measuring device 51 will record the reading.
[0044] During the "block", the various factors described above are
recorded and can then be used to determine and evaluate the
player's performance. This is accomplished because the machine has
recorded the weight of the player, the time of the player, and the
force exerted by the player. These various factors can be analyzed
on their own or alternatively, a formula, as for example,
(weight/time)*force=F/100, may be utilized in order to arrive at a
performance number or factor 160. Consequently, an athlete's
performance can be objectively determined by utilizing the training
apparatus of the present invention. For example, by using the
present invention an athlete's response to a particular workout
regime (i.e. the athletes increase or decrease in weight, response
time, and exerted force) can be objectively and consistently
measured. Of course, the data can be used for numerous reasons and
in many ways. For instance, the data may be used to determine how
well an injury is healing, whether the player is being effected by
outside factors (drugs, Physicological factors, etc.), to analyze
and determine the players initial performance, or their performance
over time. This is particularly useful as a player's initial
response may be measured, and then subsequently measured during the
training season. As the machine will record these various readings
and factors over time, the player's performance can be graphed to
indicate whether the players performance is increasing or
decreasing, and player's routine can then be adjusted such that the
player is always working at peak performance. However, the machine
can also be used in numerous other ways. To whit, the machine gives
athletes and their trainers a powerful tool to objectively,
accurately, and consistently track the performance of their
players. Furthermore, it is even envisioned that with extensive use
and analysis with this machine, a player's career ability could be
indicated by initial use of the machine. This may be accomplished
be utilizing the performance factor to determine a factor of
initial performance that may characterize the ability of an athlete
upon a single use of the present invention. This would allow the
coaches a simple tool which could then be used, in whole or in
part, to decide which players will make the team, get scholarships,
etc.
[0045] The present invention also includes a method for measuring
the performance of an athlete. The method can be practiced with or
without the aforementioned athletic machine and includes utilizing
a first sensor 31 to determine the weight of an athlete, and
communicating the weight to a computer 91, wherein computer 91
records the weight measurement. The athlete then initiates
movement, the movement typically being a standard blocking maneuver
as is done on a standard blocking and tackling machine which are
well known in the art. The athlete then exerts force against a pad
50 or other item, and a second sensor 51 records the exerted force
and communicates the force to computer 91. The athlete's time is
then measured by one or more third sensors 72, from some first
position to some intermediate or final position, and the time is
communicated to and recorded by computer 91. The computer 91 than
applies an algorithm or formula 150 in the form of
(weight/time)*force=F+100 utilizing each of the results from the
first 31, second 51, and third sensors 72 and determines a
performance factor 160 based on the input of the first 31, second
51, and third sensors 71 results.
[0046] As best illustrated by FIG. 5, the above described method
for measuring the performance of an athlete can be practiced in
conjunction with the aforementioned athletic machine, wherein the
method 110 includes measuring the weight, acceleration, and exerted
force of an athlete on an apparatus 2 which includes a generally
horizontal base 10 having a first end 14 and a second end 16,
wherein base 10 is adapted to be disposed on a ground surface. A
first sensor 31 is disposed at first end 14, and is operably
connected to base 10 such that when the athlete is positioned on a
first portion 12 on base 10, first sensor 31 measures the weight of
the athlete. The apparatus also includes a force receiving area 50
adapted to be disposed above base 10 in proximity with the second
end 16 thereof. A second sensor is also operably connected to force
receiving area 50 such that when an athlete exerts a force on force
receiving area 50, second sensor 51 measures the force exerted by
the athlete. A computer 91 is provided and operably connected to
base 10 for communication with the first, second, and third
sensors, 31, 51 and 72, respectively, and adapted to record the
measurements from the sensors and graphically display one or more
results. As illustrated by FIG. 5, the method includes having a
technician start the computer and checks for proper operation
(118). The technician will then type in a subjects vital
information on a profile page (122), and the subject steps onto an
electronic scale or sensor 31 in the basic model, or onto base 10
of a deluxe model, to record the subject's weight. This data is
then saved into a data profile (126). Any number of tests or
sequences can be used in this method. Two such tests are the "run
block" and the "pass block" (130). With the run block, the subject
begins the test by assuming the proper stance, for example a three
or four-point-stance as is known in the art, and upon assuming this
stance the subjects helmet activates a pre-stage test sensor 71. An
audible sound may be generated by pre-stage sensor 71 if the
athlete is not in the correct position. With the pass block, the
subject assumes a position with their back towards pad 50 and the
subjects helmet activates pre-stage sensor 71 (130). The subject is
then instructed begin the test (134). With the run block, the
subject begins the test by moving forward until the subjects helmet
activates sensor 72 and applies either the right or left shoulder,
forearms, or hands to pad 50 while driving with their legs for the
required period of time. With the pass block, the subject assumes a
position with their back towards pad 50. Again, the subjects helmet
activates pre-stage sensor 71. The test begins when the subject
moves backwards until pad 50 contacted (138). The technician then
saves the test results. For example, the time required to contact
pad 50 and the force output curve over the required time (on the
base model) as well as leg drive force and frequency on the deluxe
model, to the subject data profile (142). Finally, the data is
analyzed (146).
[0047] Advantageously, the athletic training apparatus of the
present invention allows an athlete's performance to be objectively
recorded, and analyzed. Objective measurement of athletic ability
is particularly beneficial for training since this provides the
athlete with the ability to identify those abilities and skills
which require the most attention, and to measure the performance
increase thereof. In addition, it is highly advantageous for a
coach or other training professional, and useful to evaluate a
player's ability through a standardized system utilizing
objectively obtained data. In this manner, an athlete may be
evaluated for performance, as well as against other athletes, in a
strictly objective manner that has heretofore been unknown. The use
of this device allows for objectively measuring an athlete's
performance and skill and can greatly assist not only athletes in
reaching their potential, but also the trainers in evaluating and
assessing the athlete's ability.
[0048] The solutions offered by the invention herein have thus been
attained in an economical, practical, and facile manner. To whit, a
novel athletic training apparatus which is able to objectively
measure an athlete's performance has been invented. While preferred
embodiments and example configurations of the inventions have been
herein illustrated, shown, and described, it is to be appreciated
that various changes, rearrangements, and modifications may be made
therein, without departing from the scope of the invention as

and configurations disclosed herein are illustrative of the
preferred and best modes for practicing the invention, and should
not be interpreted as limitations on the scope of the invention as
defined by the claims, and it is to appreciated that various
changes, rearrangements, and modifications may be made therein,
without departing from the scope of the invention as defined by the
claims.
