CROSS REFERENCES TO RELATED APPLICATIONS
[0001] This application is a continuation of U.S. patent
application Ser. No. 14/886,987, filed on Oct. 19, 2015, which is a
continuation of U.S. patent application Ser. No. 14/505,804, filed
on Oct. 3, 2014 and issued as U.S. Pat. No. 9,186,446, which claims
the benefit of U.S. patent application Ser. No. 11/784,021, filed
on Apr. 5, 2007 and issued as U.S. Pat. No. 8,852,149, which claims
the benefit of U.S. Provisional Patent Application No. 60/789,817,
filed on Apr. 6, 2006. The disclosures of these prior applications
are incorporated by reference in their entirety.
BACKGROUND
[0002] The present invention generally relates to an appliance and
methods that may be used to provide instruction in how to use a
medical device to provide medical treatment to a person. More
specifically, the present invention is comprised of an appliance
that integrates the medical device with other hardware and software
that may be used to provide a medical practitioner using the
medical device with information regarding the use and operation of
the medical device.
[0003] As medical technology continues to advance, new medical
devices are continually becoming available for use by healthcare
practitioners. Because of the relatively large number of these new
devices, healthcare practitioners may have difficulty in retaining
knowledge regarding the use of the devices. If a healthcare
practitioner is unfamiliar with a medical device, patient safety
may be compromised if the practitioner is unable to complete, or
incorrectly completes, a course of treatment because he or she
fails to have adequate knowledge of use of the device.
[0004] Keeping apprised of the proper use of new medical devices,
however, represents a number of challenges. For example, it is
typically difficult for busy healthcare practitioners to find time
to read an instruction manual for a medical device. This means of
instruction is also inefficient for many people who tend to be more
visually oriented. Where a hands-on approach to learning is more
efficient, it is often necessary to attend a class or have personal
instruction in how to use the device. This may be difficult because
of time constraints or scheduling problems. Even if the healthcare
practitioner has received instruction in the use of a medical
device, problems may arise if significant time has elapsed since
the last use of the device. For example, the practitioner may find
himself or herself in a position of suddenly realizing that crucial
information has been forgotten in the midst of providing treatment
using the device. There may be no convenient way to reacquire this
missing information, so that patient safety may be compromised as a
result.
[0005] There is therefore a need for a system that provides
efficient instruction regarding the use and operation of medical
devices to perform their intended medical treatment. Preferably,
this system provides a hands-on approach to learning without the
need for a separate training class or personal instruction. The
system should also provide ready access to instruction while using
the medical device, so that instruction may be readily obtained
while the device is in use. Finally, the system should allow the
practitioner quick and easy access to the portion of the
instructional materials that are necessary.
SUMMARY
[0006] The present invention is directed to an appliance and
methods that satisfy the needs described above. As described in
greater detail below, they have many advantages over existing
instructional apparatus and methods when used for their intended
purpose, as well as novel features that result in a new
instructional appliance and methods that are not anticipated,
rendered obvious, suggested, or even implied by any of the prior
art apparatus or methods, either alone or in any combination
thereof.
[0007] In accordance with the present invention, an appliance is
provided for administering medical treatment to a person, in which
the appliance also provides ready and convenient access to
instruction in the use of the appliance in a manner that overcomes
the disadvantages of currently existing apparatus. In one
embodiment of the present invention, the appliance is comprised of
a medical device, a electronic processor, and display means, which
are described in more detail below. The medical device is generally
adapted to provide the desired medical treatment to the person. The
electronic processor is positioned on or within the medical device,
and is adapted so that video content relating to use and operation
of the medical device is digitally stored within the electronic
processor. The display means, which are described in more detail
below, visually display the video content digitally stored within
the electronic processor. The display means are also positioned on
a surface of the medical device, and are electronically connected
to the electronic processor. The display means are capable of
displaying the video content so that the user of the appliance has
access to video information regarding use and operation of the
medical device.
[0008] As a result, the appliance of the present invention meets
the needs described above in the Background section. For example,
the appliance provides efficient instruction regarding the use and
operation of the medical device in performing its intended medical
treatment. The video content digitally stored in the electronic
processor contains this information. The video content is also
typically indexed so that different portions of the stored
instructional information may be accessed as desired by the
healthcare practitioner. Because the appliance generally provides
video instruction, it overcomes the monotony and frustration
associated with merely reading an instruction manual. The appliance
also provides a hands-on approach to learning without the need for
a separate training class or personal instruction. Because the
medical device is integrated as a part of the appliance, the
appliance provides ready access to instruction while using the
medical device. Thus, the practitioner may readily obtain
instruction even while using the medical device to provide medical
treatment. This may enhance patient safety where instructional
information becomes necessary during the course of the treatment.
It is to be noted that almost any medical device may be used as a
part of the appliance, as long as its physical dimensions and
complexity allow for and warrant use of the instructional system
encompassed within the appliance.
[0009] In some embodiments of the present invention, the display

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] In accordance with the present invention, an appliance and
methods for using the appliance are provided for administering
medical treatment to a person. The word "person" is to be broadly
construed and may encompass animals as well as humans. Although the
description of the present invention set forth herein is directed
primarily toward use of the appliance and methods for treatment of
wounds and other infirmities on a portion of a person's body, the
term "medical treatment," as used herein, may also include any
other type of treatment or activity conducted for purposes of
examination, diagnosis, treatment, cure or relief of any disease,
condition or malady, or for other purposes related to the health
and well being of the person. Such uses are encompassed within the
scope of the present invention to the extent they are included
within the scope of the appended claims.
[0019] An embodiment of an appliance 10 of the invention is
illustrated in perspective view in FIG. 1. A schematic diagram of
the appliance 10 of FIG. 1 is set forth in FIG. 2, in which the
components of the appliance 10 other than those related to the
particular medical device 20 utilized as a part of the appliance 10
are illustrated. It is to be noted that the various components
comprising the medical device 20 are dependent upon the type of
medical device 20 incorporated as a part of the appliance 10, and
are not relevant to the present invention, as described in more
detail below. In this embodiment, the appliance 10 is generally
comprised of a medical device 20, an electronic processor 30
(illustrated schematically in FIG. 2), display means 40
(illustrated schematically in FIG. 2, and as a liquid crystal
display 41 in FIG. 1, which are described in more detail below),
audio output means 50 (illustrated schematically in FIG. 2, and as
a piezoelectric device 51 in FIG. 1, which are described in more
detail below), electronic input means 60 (illustrated schematically
in FIG. 2, and as a DVD drive 61 and a Universal Serial Bus (USB)
port 65 in FIG. 1, which are described in more detail below), an
electronic storage device 70 (illustrated schematically in FIG. 2,
and as a DVD 71 and a flash storage device 75 in FIG. 1, which are
described in more detail below), and electronic control means 80
(illustrated schematically in FIG. 2, and described in more detail
below).
[0020] The medical device 20 is adapted to provide medical
treatment to a person (not illustrated). In the illustrated
embodiment, the medical device 20 is a medical grade vacuum pump 21
that acts as a source of negative pressure for purposes of negative
pressure wound therapy. This type of vacuum pump and its use for
purposes of negative pressure wound therapy are described in more
detail in U.S. Pat. No. 7,128,735, issued to Richard Scott Weston,
the disclosure of which is incorporated herein by reference.
Generally, the vacuum pump 21 is further comprised of a vacuum
gauge 22 to measure negative pressure produced by the vacuum pump
21, an on/off switch 23 for vacuum pump 21 operation, and a knob 24
for control of the negative pressure level to be created by the
vacuum pump 21. A connector 25 is used to connect the vacuum pump
21 to one end of a length of flexible tubing (not illustrated and
not material for purposes of this disclosure), which is connected
at its other end to a wound dressing (not illustrated and not
material for purposes of this disclosure). It is to be noted that
in other embodiments of the present invention the medical device 20
may be comprised of almost any type of medical device currently
known in the relevant art or that may be developed in the relevant
art in the future, as long as the medical device 20 has physical
dimensions adequate to house the remaining components comprising
the appliance 10 and the complexity of use and operation of the
medical device 20 is such that instruction in such use and
operation may be desirable.
[0021] When the user of the appliance 10 desires to receive
instruction in the use and operation of the medical device 20, he
or she manipulates the electronic control means 80 (as described in
more detail below), designating the training materials he or she
desires to observe. The video and audio content comprising the
training materials are digitally stored within data storage media
comprising the electronic processor 30 (as described in more detail
below) or on one or more electronic storage devices 70, 71, 75 (as
described in more detail below). The electronic processor 30 also
controls the operation of the display means 40, 41, the audio
output means 50, 51, and the electronic input means 60, 61, 65, all
of which are described in more detail below. When electronically
directed by the electronic control means 80, the electronic
processor 30 calls for and receives the video and audio content
that is digitally stored within the data storage media comprising
the electronic processor 30 (as described in more detail below) or
received from the electronic storage device 70, 71, 75 through the
electronic input means 60, 61, 65 (as described in more detail
below). The electronic processor 30 then transmits the selected
video content to the display means 40, 41, and the selected audio
content to the audio output means 50, 51. The user of the appliance
10 is then able to visually observe the video content, as it is
displayed on the display means 40, 41, and to hear audio content,
as it is broadcast from the audio output means 50, 51.
[0022] It is to be noted that the "video content" and "audio
content" comprising the training materials, as such terms are used
herein, are typically coordinated so that the audio content
accompanies the video content, as would be the case in viewing a
full-motion video of a person describing how to use a feature of
the medical device 20. In some embodiments, however, there may be
reasons for including separate video or audio content, such as an
audible alarm where the audio output means 50, 51 are also used as
a part of the medical device 20, or a visual chart where the
display means 40, 41 are also used to display information (such as
negative pressure levels over time) related to operation of the
medical device 20. Further, the training materials may take any
suitable form that may be useful for providing instruction in the
use and operation of the medical device 20, such as full-motion
video, static photographs, slides, charts, graphs, graphics,
drawings, depictions, plans, specifications, or other types of
related information or combinations thereof.
[0023] The electronic processor 30 of the appliance 10 is
illustrated schematically in FIG. 2. The electronic processor 30 is
not illustrated in FIG. 1, however, because it is positioned within
the casing of the vacuum pump 21. In the embodiment of the
invention illustrated in FIG. 1, all of the functions of the
electronic processor 30 are performed by a single electronic
processor 30. In other embodiments of the invention, however, the
various processor-related functions of the electronic processor 30
may be performed by separate electronic processors or combinations
of electronic processors. The preferred number of electronic
processors comprising the electronic processor 30 depends upon the
function or functions to be performed by the electronic processor
30. For example, the electronic processor 30 may be comprised of
multiple processors where multiple types of electronic input means
60 are provided. Generally, and referring again to the embodiment
of the invention illustrated in FIG. 1 and FIG. 2 as an example,
the electronic processor 30 may be comprised of one or more
integrated circuits, printed circuits, and hybrid circuits or any
combination of such circuits currently known in the relevant art or
developed in the relevant art in the future. In addition, passive
and active circuit components may be used in conjunction with one
or more of such circuits where the functions to be performed by the
electronic processor 30 require such components. Such circuits may
be constructed of a rigid, semi-rigid, or flexible substrate
material.
[0024] The type of electronic processor 30 is generally dependent
upon the type of display means 40, 41, the type of electronic input
means 60, 61, 65, the type of audio output means 50, 51, the type
of electronic storage device 70, 71, 75, and the type of electronic
control means 80 to be utilized in the appliance 10. For example,
the electronic processor 30 includes circuits necessary to
electronically operate the display means 40. In the illustrated
embodiment of the appliance 10, the electronic processor 30 may
include a driver circuit, which is used to develop the voltages
appropriate to activate and deactivate the pixels of display means
40 comprised of a liquid crystal display (LCD) 41. The electronic
processor 30 may also include a polarity switcher at the output of
the driver circuit that selects whether the row or column electrode
of the LCD display 41 is to receive the positive polarity, while a
row/column selector switch determines which specific row/column
pair of the LCD display 41 receives the voltages produced by the
polarity switch and the driver circuit. In some embodiments of the
invention, the electronic processor 30 may also comprise one or
more additional electronic data storage media (not illustrated),
which may be comprised of almost any portable data storage media
currently known in the relevant art or that may be developed in the
relevant art in the future. For example, such data storage media
may include one or more additional memory boards or integrated
circuits or a part of the integrated circuit or circuits comprising
the electronic processor 30. Alternatively, such electronic data
storage media may also include one or more of each of the following
devices in electronic communication with the circuits comprising
the electronic processor 30: optical storage device (such as
compact disc, digital versatile disc (sometimes also referred to as
digital video disc or "DVD"), hard drive device, flash memory data
storage device, or combinations of such devices. The preferred data
storage media is dependent upon the types of devices comprising the
remaining portions of the appliance 10 (without considering the
medical device 20), as well as the type and quantity of audio
content and video content to be utilized by the appliance 10. The
more preferred data storage media is a hard drive device or flash
memory data storage device. The electronic processor 30 may also be
adapted to receive information from the medical device 20 in a
compatible digital form so that such information may be displayed
on the display means 40, 41 or broadcast by the audio output means
50, 51. Such information may include medical device 20 operating
parameters (such as periodic pressure level measurements), alarm
notifications (such as a low vacuum alarm signal), and other
information related to the use, operation and function of the
medical device 20.
[0025] Preferably, the electronic processor 30 is a modular
integrated circuit or combination of integrated circuits, including
suitable data storage media, adapted to perform the functions
desired of the appliance 10. These functions generally include: (a)
electronically interacting with the electronic storage device 70,
71, 75 through the electronic input means 60, 61, 65; (b)
receiving, recording, storing, and processing the digital audio
content and video content; (c) electronically interacting with the
electronic control means 80 to receive electronic instructions from
the user; and (d) electronically interacting with the display means
40, 41 to display the video content and with the audio output means
50, 51 to broadcast the audio content. Examples of electronic
processors suitable for use as the electronic processor 30 are well
known in the relevant art.
[0026] The electronic processor 30 may be included as a part of a
circuit board (not illustrated) that comprises the medical device
20 (vacuum pump 21). Alternatively, the electronic processor 30 may
be positioned in any suitable area within the casing of the vacuum
pump 21, may be incorporated as a part of any suitable component
(not illustrated) comprising the vacuum pump 21, or may be wholly
or partially embedded in or attached to the casing of the vacuum
pump 21. The electronic processor 30, the display means 40, 41, the
audio output means SO, 51, and the electronic input means 60, 61,
65, are provided with electrical energy required for their
operation by a power supply 26. Preferably, the power supply 26 is
the same power supply unit that powers the medical device 20, so
that a separate power supply 26 dedicated solely to the electronic
processor 30 is not necessary. In such cases, the power supply 26
may typically be a battery (not illustrated) or an external source
of power, such as electricity supplied by a standard 120 volt, 60
Hz AC outlet (not illustrated). Additional electronic circuitry and
components (such as transformers or converters) may be required to
step-up or step-down the electrical current supplied by the power
supply 26 for use by the electronic processor 30 and the components
of the appliance 10 that it controls. Where a separate, dedicated
power supply 26 is necessary, the power supply 26 may be comprised
of one or more of almost any compact, portable source of electrical
energy known in the relevant art or developed in the relevant art
in the future, such as a battery. In other embodiments of the
invention, the power supply 26 may also be comprised of one or more
devices that are used to collect solar or other electromagnetic
energy and convert such energy to a form appropriate for powering
the electronic processor 30 and the components of the appliance 10
that it controls. For example, the power supply 26 may be comprised
of one or more photoelectric cells fabricated from a silicon
compound. The type of power supply 26 to be used in any particular
embodiment of the appliance 10 is dependent upon the anticipated
use of the appliance 10 and the individual preference of the user
of the appliance 10. Preferably, the power supply 26 is a
re-chargeable lithium-ion battery that is rechargeable by
connecting it to a standard 120 volt, 60 Hz AC outlet. The power
supply 26 is electronically connected to the electronic processor
30 by one or more circuit elements 29 (illustrated schematically in
FIG. 2, but not illustrated in FIG. 1), as described in more detail
below. Some embodiments of the appliance 10 may also include power
reduction means (not illustrated) to decrease the consumption of
electrical power by the components of the appliance 10 other than
the medical device 20. An example of such means is described in
U.S. Pat. No. 5,931,764 to Viztec, Inc., which is incorporated
herein by reference. Other embodiments may also include means to
recharge the power supply 26, such as the use of direct electrical
contacts, RF signals, inductive, solar-galvanostatic,
potentiostatic, and other charging means currently known in the
relevant art or developed in the relevant art in the future. To
accomplish such charging, the power supply 26 or the electronic
processor 30 may include a regulator control circuit that accepts
current and voltage from an external power source for storage in
the power supply 26. An example of such means is described in U.S.
Pat. No. 5,931,764 to Viztec, Inc., which is incorporated herein by
reference.
[0027] In the embodiment of the invention illustrated in FIG. 1 and
FIG. 2, the appliance 10 further comprises electronic control means
80, which enable the user of the appliance 10 to control or provide
other input regarding the various functions performed by the
electronic processor 30. For example, in the embodiment of the
invention illustrated in FIG. 1 and FIG. 2, the appliance 10
generally has an on/off switch 27, which is comprised of a standard
toggle-type of electrical switch, and is used to turn the
electronic processor 30 on and off. In addition, the appliance
includes a knob 28, which may be used to select various portions of
the video content and audio content available for display on the
display means 40, 41 and broadcast over the audio output means 50,
51. Other embodiments of the invention may also comprise other
electronic control means 80, which may include any suitable means
that are currently known in the relevant art or that may be
developed in the relevant art in the future to provide data or
control input in electronic form. Examples of such means include
rheostats, potentiometers, switches, relays, touch screen LCD's,
and other input means, and combinations of the foregoing. Another
example is a voice activated electronic control means 80. For
example, where the audio output means 50, 51 is comprised of a
piezoelectric device 51 that may act as both a speaker and a
microphone, the piezoelectric device 51 may be used to receive
voice commands from the user of the appliance 10 and convert those
commands to digital signals that are electronically transferred to
the electronic processor 30. The electronic processor 30 may then
convert the digital signals to electronic commands that govern the
operation of the electronic processor 30, allowing for hands-free
operation of the informational aspect of the appliance 10. The
electronic control means 80 are electronically connected to the
electronic processor by one or more circuit elements, as described
in more detail below. For example, in the embodiment of the
invention illustrated in FIG. 1 and FIG. 2, the switch 27 and the
knob 28 are connected to the electronic processor 30 by insulated
copper wires 81 (illustrated schematically in FIG. 2, but not
illustrated in FIG. 1).
[0028] In the embodiment of the invention illustrated in FIG. 1 and
FIG. 2, the appliance 10 is also comprised of electronic input
means 60 (illustrated as DVD drive 61 and USB port 65 in FIG. 1,
and schematically as "Input Port" in FIG. 2), and electronic
storage devices (illustrated as DVD 71 and flash storage device 75
in FIG. 1, and schematically as "Storage Device" in FIG. 2).
Generally, each electronic storage device 70, 71, 75 digitally
stores audio content and video content comprising the training
materials and corresponds to a compatible electronic input means
60, 61, 65, respectively. For example, the electronic input
receptacle DVD drive 61 is used with the DVD 71 and the flash
storage device 75 is used with the electronic input receptacle USB
port 65. It is to be noted that the audio content and video content
comprising the training materials may be stored on more than one
electronic storage device 70, 71, 75. The DVD drive 61 and the USB
port 65, as well as their corresponding DVD 71 and flash storage
device 75, respectively, are well known in the art. In other
embodiments of the invention, the electronic storage devices 70,
71, 75 and their corresponding compatible electronic input means
60, 61, 65 may be comprised of any suitable means currently known
in the relevant art (such as floppy discs and compact discs) or
developed in the relevant art in the future that may be used for
storing electronic data in digital form. More than one type of
electronic storage device 70, 71, 75 and corresponding compatible
electronic input means 60, 61, 65 may be used with any particular
embodiment of the appliance 10. The preferred type and number of
electronic storage devices 70, 71, 75 and corresponding compatible
electronic input means 60, 61, 65 to be utilized in any particular
embodiment of the appliance 10 is dependent upon the size and
complexity of the medical device 20, the type and quantity of audio
content and video content involved, the preference of the user of
the appliance 10, and other factors. Further, the electronic input
means 60, 61, 65 may be placed in any suitable position on the
surface of the medical device 20. The electronic input means 60,
61, 65 are electronically connected to the electronic processor 30
by one or more circuit elements, as described in more detail below.
For example, in the embodiment of the invention illustrated in FIG.
1 and FIG. 2, the electronic input means 60,61, 65 are connected to
the electronic processor 30 by insulated copper wires 69
(illustrated schematically in FIG. 2, but not illustrated in FIG.
1).
[0029] In the embodiment of the invention illustrated in FIG. 1 and
FIG. 2, the appliance 10 is comprised of display means 40, 41,
which receive data and information (as video content) from the
electronic processor 30 and optically display such data and
information in a format that may be observed from above the surface
of the appliance 10. In other embodiments of the invention, the
appliance 10 may have two or more electronic displays 41 comprising
the display means 40. The number of electronic displays 41 is
generally dependent upon the physical shape and configuration of
the appliance 10, the position of the user of the appliance 10
while the appliance 10 is in use, the preferences of the user of
the appliance 10, and other factors. Preferably, a single
electronic display 41 displays all data and information comprising
the video content supplied by the electronic processor 30. The
electronic display 41 is electronically connected to the electronic
processor 30 by one or more circuit elements 42 (illustrated
schematically in FIG. 2, but not illustrated in FIG. 1), as
described in more detail below.
[0030] In the embodiments of the invention illustrated in FIG. 1
and FIG. 2, the display means 40, 41 are comprised of an LCD
display. In other embodiments of the invention, the display means
40, 41 may be comprised of any suitable type of miniature, portable
display device currently known in the relevant art or developed in
the relevant art in the future that is capable of receiving data
and information from the one or more electronic processors and
displaying such data and information in a format that may be
optically observed. For example, the display means 40, 41 may be
comprised of LED, plasma, electronic papers (e.g., GYRICON,
choleteric nematic phase transition, and IRIDIGM), and similar
types of displays. The type of display means 40, 41 is dependent
upon the preferences of the user of the appliance 10, the functions
to be performed by the appliance 10, the video content to be
displayed by the display means 40, 41, the expected use of the
appliance 10, and other factors. It is to be noted that more than
one type of display means 40, 41 may be used in the various
embodiments of the invention. It is also to be noted that the
display means 40, 41 may be of almost any shape currently known in
the relevant art or developed in the relevant art in the future.
For example, the electronic display 41 of the appliance 10
illustrated in FIG. 1 is generally rectangular in shape. In
addition, in various embodiments of the invention, the display
means 40, 41 may display data and information in any format desired
by the user of the appliance 10. For example, the electronic
display 41 in the embodiment illustrated in FIG. 1 may display a
video of a person explaining a particular feature of the medical
device 20 on the top portion thereof, while data and information
related to operation of the medical device 20 (such as a chart of
negative pressure level variance over time) is displayed on the
bottom portion thereof.
[0031] Preferably, as illustrated in FIG. 1, the display means 40,
41 of the appliance 10 has one electronic display 41 that is
comprised of an LCD electronic display 41. Referring to the
embodiment of the invention illustrated in FIG. 1 and FIG. 2 as an
example, the LCD electronic display 41 may be constructed of rigid,
semi-rigid, or flexible materials, such as glass and suitable
transparent polymers (e.g., polyvinyl chloride or polycarbonate).
The type of material used to construct the LCD electronic display
41 is dependent upon the anticipated use of the appliance 10, the
desired flexibility of the appliance 10, the desired aesthetic
appearance of the appliance 10 in accordance with the individual
taste of the user of the appliance 10, and other factors. In
different embodiments of the invention, the LCD electronic display
41 may provide information in full-motion video, in static display,
in black and white, and in one or more colors and combinations of
colors and different shades of the same color. In addition, the LCD
electronic display 41 may be constructed of bi-stable or
multi-stable display material, such as a ferroelectric LCD based
upon smectic liquid crystals typically of the C phase that exhibit
chiral behavior, that will maintain an image when power has been
removed. In addition, the LCD electronic display 41 may be
constructed in a manner so that it provides stereoscopic effects,
such as images that appear three-dimensional and images that alter
their appearance based upon a viewing angle. This type of display
is described in U.S. Pat. No. 5,931,764 to Viztec, Inc., which is
incorporated herein by reference. Further, the LCD electronic
display 41 may incorporate a "touch screen" feature (as all or a
portion of the electronic control means 80), so that data may be
input into the electronic processor 30 by touching a portion of the
surface of the LCD electronic display 41. Resistive, projected,
surface capacitive, IR, surface wave, and other similar types of
LCD displays currently known in the relevant art or developed in
the relevant art in the future may be used for this purpose. More
preferably, the LCD electronic display 41 is an LCD utilizing

embodiments, the audio output means 50, 51 may be comprised of any
suitable speaker-type device (such as standard magnet-based
speakers or headphones) or combinations of such devices currently
known in the relevant art or that may be developed in the relevant
art in the future. The audio output means 50, 51 is electronically
connected to the electronic processor 30 by one or more circuit
elements 52 (illustrated schematically in FIG. 2, but not
illustrated in FIG. 1), as described in more detail below.
[0033] The electronic processor 30 is electronically connected to
the display means 40, 41, the audio output means 50, 51, and the
electronic input means 60, 61, 65 by one or more circuit elements
29, 42, 52, 69, 81. For example, in the embodiment of the invention
illustrated in FIG. 1 and FIG. 2, circuit elements 29, 42, 52, 69,
81 are generally comprised of electrically conductive wires or
ribbons. In other embodiments of the invention, the one or more
circuit elements 29, 42, 52, 69, 81 may be any suitable
electrically conductive connectors currently known in the relevant
art or that may be developed in the relevant are in the future,
such as electrically conductive ribbons, strips, inks and similar

circuit elements 42 comprised of direct electrical contact between
the leads on the circuits comprising the electronic processor 30
and the leads on the electronic display 41 in cases where the
electronic processor 30 and the electronic display 41 are
integrated as a single unit. The preferred circuit elements 29, 42,
52, 69, 81 are dependent upon the nature of the device to be
connected to the electronic processor 30, the design, relative
position, and configuration of such devices and the circuit
elements 29, 42, 52, 69, 81, and other factors. The preferred
circuit elements 29, 42, 52, 69, 81 are a direct electrical contact
between the electronic processor 30 and the devices to which it is
connected using the circuit elements 29, 42, 52, 69, 81,
respectively.
