Description
Title of the invention: partition for a vehicle comprising an assistance device for the evacuation of persons via an emergency exit in the partition
[0001] The present invention lies in the field of safety devices for vehicles, and aircraft in particular. The present invention relates to a vehicle partition comprising an assistance device for the evacuation of persons via an emergency exit in the partition.
[0002] Such an assistance device can be arranged in many vehicles, including an aircraft, or even possibly in a building.
[0003] For example, a vehicle, and in particular an aircraft, may include one or more emergency exits for evacuating, if necessary, individuals present in this vehicle. The expression "emergency exit" designates an opening, possibly obstructed by a panel and possibly a porthole, through which an individual can escape after ejection from the panel.
[0004] However, smoke may be released during the evacuation and may disrupt the vision of individuals. Such smoke then makes it difficult to locate an emergency exit, and in particular the nearest emergency exit, especially during an anxiety-provoking moment. Similarly, in the event of a water landing, water may enter the vehicle, also making it difficult to locate emergency exits.
[0005] At night, the interior lighting of the vehicle may also be out of service, the emergency exits then no longer being clearly visible and identifiable.
[0006] Therefore, certain regulations may require the presence of emergency exit indication devices, for example in buildings open to the public or in vehicles, and aircraft in particular.
[0007] In the field of helicopters, regulation CS29.812 requires the installation of an emergency evacuation lighting device designated by the acronym HEEL for the English designation "Helicopter Emergency Egress Lighting". This regulation requires the use of an emergency lighting system around emergency exits.
[0008] The lighting must be clearly visible under all conditions, in particular to allow its viewing in the presence of smoke, water or in the dark.
[0009] A HEEE emergency exit lighting system that is widespread today and complies with regulations comprises several electrically powered light segments fitted with bulbs or light-emitting diodes. These various light segments are distributed around the emergency exit(s) in order to partially frame each emergency exit by emitting, when necessary, a monochrome light, for example blue or green, capable of being visible in degraded vision conditions. Such an emergency exit lighting system may comprise an electric battery and an inverter in order to power the light strips as described in document US 4365232.
[0010] Document EP 2278566 describes that such emergency exit lighting systems may be provided with sensors and a control unit for detecting one or more triggering conditions of the lighting system. The sensors comprise, for example, a pulse detector, and / or any type of sensors.
[0011] Such lighting systems can have a significant bulkiness, and also a significant mass. In addition, they can be difficult to integrate on partitions having complex geometries. Furthermore, these lighting systems are limited to indicating emergency exits for individuals located inside the aircraft.
[0012] Other systems are known. Document US 4521835 describes an emergency lighting system comprising a plurality of light-emitting diodes mounted on a semi-rigid bar.
[0013] Document US 2009 / 0309763 describes luminous elements mounted on the edge of portholes. These luminous elements partially or completely frame the portholes. These luminous elements are in the form of luminous strips comprising a photoluminescent material.
[0014] Document US 2014 / 0070047 describes a structural element comprising alternating conductive layers and insulating layers. Each conductive layer is electrically connected to an electrical power source as well as to output devices, for example lighting devices, in order to electrically power these output devices.
[0015] Document EP 1017953 describes a chemically activated emergency exit lighting system. This system uses two chemical agents that emit light when mixed together. Once mixed, the two chemical agents are sent into a transparent conduit arranged around the emergency exit.
[0016] Document US6843010 is distant from the present disclosure by describing a luminous sign.
[0017] The present invention therefore aims to propose an innovative assistance device facilitating the evacuation of people via an emergency exit. Such an assistance device can be used in any vehicle, but also in other circumstances, for example within a building.
[0018] The present invention thus aims at a partition for a vehicle comprising a structure delimiting an opening forming an emergency exit, the partition comprising a movable panel closing the emergency exit and at least one ejection handle allowing ejection of the panel, the partition comprising an assistance device comprising an electrical power supply device electrically supplying an electrical circuit, the assistance device comprising light emitters electrically connected to the electrical circuit, the light emitters generating light when the electrical circuit is electrically supplied by the electrical power supply device.
[0019] The partition is remarkable in that the light emitters comprise at least a first emitter emitting a first light of a first color and at least partially framing the panel as well as at least a second emitter emitting a second light of a second color distinct from the first color and indicating a position of the ejection handle.
[0020] The assistance device can be activated in the usual manner during an evacuation, for example following an accident or even a water landing in the particular case of an aircraft. The assistance device can be activated manually using a switch by the pilot of the vehicle, a crew member, or even a passenger. In a complementary or alternative manner, the assistance device can be activated automatically using one or more sensors, detecting for example an impact, a sharp deceleration or an immersion.
[0021] A switch or sensor then controls the electrical supply of the electrical circuit by the electrical supply device, the light emitters being electrically supplied and emitting the first light and the second light.
[0022] The assistance device then makes it possible, once activated, to facilitate access for individuals to an emergency exit and thus to assist their evacuation from the vehicle via this emergency exit, on the one hand by clearly indicating the position of the emergency exit using the first light emitter(s) and, on the other hand, by also clearly and distinctively indicating the position of the ejection handle(s) using the second emitter(s).
[0023] In fact, once in front of the partition, the individuals to be evacuated quickly see, thanks to the second light emitted by the second transmitter(s), the ejection handle(s) allowing the movable panel to be ejected. These individuals then have access to the emergency exit.
[0024] The first and second colors are defined to allow an individual to clearly identify where the emergency exit and the ejection handle(s) are located. For example, the first color may be predominantly green or blue while the second color may be red or orange. These colors make it possible in particular to clearly identify where the emergency exit and the ejection handle(s) are located. underwater ejection handles.
[0025] The shape and / or arrangement of each first emitter and each second emitter may also allow them to be significantly differentiated. For example, a first emitter mostly, or even completely, surrounds the movable panel. Conversely, a second emitter is positioned only very partially around the panel, close to an ejection handle, or may be offset to be positioned on or around the ejection handle.
[0026] Furthermore, the electrical power supply device of the assistance device may be shared with other devices or systems of a vehicle, or even connected to a centralized electrical power source of the vehicle. The electrical power supply device may alternatively be independent and autonomous, and comprise for example an alternating current generator or a battery coupled to a direct / alternating converter.
[0027] The assistance device may be arranged on the structure of the partition, or even between the panel and this structure. In particular, the electrical circuit and the light emitters may be positioned on the structure of the partition, or even between the panel and this structure.
[0028] The partition according to the invention may be a fixed partition or a movable partition, forming for example a door.
[0029] The partition according to the invention may comprise one or more of the following characteristics, taken alone or in combination.
[0030] According to one possibility, said at least one first transmitter and said at least one second transmitter may be arranged solely inside a vehicle in order to primarily indicate to the passengers of the vehicle, as well as to the crew members, the emergency exit as well as the ejection handle(s).
[0031] Alternatively, said at least one first transmitter and said at least one second transmitter may be arranged solely outside the vehicle in order to primarily indicate to the rescue teams the emergency exit as well as the ejection handle(s).
[0032] Alternatively, said at least one first transmitter and said at least one second transmitter may be arranged simultaneously inside and outside the vehicle.
[0033] According to a possibility compatible with the previous ones, said at least one first emitter can emit the first light which is visually continuous and at least partially frames the panel. In this way, a light strip emitting the first color at least partially, or even completely, frames the panel.
[0034] Said at least one second emitter may be arranged at one of the ends of the light strip formed by said at least one first emitter, or even at both of its ends. The second light is thus visually continuous with the first light, jointly forming a light strip. Said at least one second emitter can thus be positioned opposite or facing one or more ejection handles.
[0035] Said at least one second emitter may also be arranged outside the light strip formed by said at least one first emitter. Said at least one second emitter may thus be positioned opposite or facing one or more ejection handles or partially or completely surround one or more handles. The second light is thus visually discontinuous from the light strip formed by said at least one first emitter.
[0036] According to a possibility compatible with the previous ones, said at least one first emitter and said at least one second emitter can respectively emit the first light and the second light which are visually continuous. In this way, a light strip comprising the first color and the second color at least partially, or even totally, frames the panel.
[0037] Said at least one second emitter can thus be positioned opposite or facing at least one of the ejection handle(s). Said at least one first emitter and said at least one second emitter are thus positioned alternately at least partially around the panel, the first light and the second light jointly forming a light strip.
[0038] According to a possibility compatible with the previous ones, the assistance device may comprise a masking covering at least partially said at least one first emitter and / or said at least one second emitter. This masking makes it possible to locally mask the first light emitted by said at least one first emitter and / or the second light emitted to form a word for example.
[0039] The masking may be total and cover one or more light emitters over a limited area, thus completely blocking the emitted light. Such total masking may thus locally block the emitted light, which is for example no longer continuous, while maintaining electrical continuity thanks to the first emitters and / or the second emitters.
[0040] The masking can also be partial and partially cover one or more light emitters, thus partially blocking the emitted light.
[0041] The partial masking may comprise, for example, one or more geometric shapes, one or more symbols, one or more letters and / or one or more numbers. This partial marking thus allows the geometric shape(s), a word, and / or a number to be displayed on the light strip formed by said at least one first emitter and said at least one second emitter.
[0042] According to a possibility compatible with the previous ones, the light emitters comprise at least a third emitter emitting a third light and the device assistance includes masking, including at least partial masking, thus at least partially covering said at least one third transmitter.
[0043] A complementary light strip, formed by the third emitter, thus makes it possible to display one or more symbols comprising, for example, one or more geometric shapes, one or more letters and / or one or more numbers.
[0044] According to a possibility compatible with the preceding ones, the light emitters may comprise electroluminescent paints or electroluminescent inks. These electroluminescent paints or electroluminescent inks comprise, for example, pigments which emit light when they are placed in a magnetic field or crossed by an electric current. Thus, when the electrical circuit is electrically powered by the electrical power supply device, the electroluminescent paints or inks emit light.
[0045] The use of such electroluminescent paints or inks advantageously makes it possible to have light emitters that are compact, in particular of very low thickness, and having a low mass. In addition, the use of such electroluminescent paints or inks also makes it possible to obtain diverse and varied, even complex, light shapes, in order to adapt in particular to the curves and relief of the structure of the partition.
[0046] According to this possibility, the light emitters may comprise a superposition of layers including at least one conductive layer, at least one electrically insulating layer, a layer of electroluminescent paint or electroluminescent ink, and at least one transparent or translucent protective layer.
[0047] When the assistance device comprises total or partial masking, a masking layer is added, for example before or after the transparent or translucent protective layer.
[0048] Alternatively or in a complementary manner, each light emitter may comprise light-emitting diodes or even an optical fiber and a light generator connected to the optical fiber.
[0049] According to a possibility compatible with the previous ones, the partition may comprise a light frame fixed to the structure of the partition, around the panel, the light frame comprising a support on which the light emitters are arranged. The light frame may also comprise the electrical circuit, or even the electrical power supply device of the assistance device, arranged on the support.
[0050] The support may have a shape and relief complementary to a shape and relief of the structure around the panel in order to adapt to the structure. In this way, the light frame integrates perfectly into the structure of the partition.
[0051] The light frame can be fixed in the usual way to the structure of the partition. For example, the support of the light frame is screwed or riveted to the structure. The support of the light frame can also be glued onto the structure.
[0052] The present invention also relates to a vehicle, for example an aircraft, comprising a partition as previously described. This partition is, for example, arranged between a cell of the vehicle and the environment external to the vehicle.
[0053] The invention and its advantages will appear in more detail in the context of the description which follows with examples given for illustrative purposes with reference to the appended figures which represent: - [Fig.l], a partition according to the invention, - [Fig.2], a partition according to the invention, - [Fig.3], a partition according to the invention, - [Fig.4], a partition according to the invention, and - [Fig.5], a section of a light emitter.
[0054] Elements present in several distinct figures are assigned a single reference.
[0055] Figures 1 to 3 show a partition 40 according to the invention. This partition 40 can be installed within various systems, and for example within a building or a vehicle 10, in particular an aircraft. This partition 40 can be a fixed partition. Alternatively, this partition 40 can be a movable partition, such as a door.
[0056] Such a partition 40 comprises a structure 41 pierced with an opening 43 forming an emergency exit 44. The partition 40 also comprises a movable panel 45 closing the emergency exit 44 and one or more ejection handles 46 allowing ejection of the panel 45. The panel 45 may be opaque, translucent or transparent. The panel 45 may comprise, for example, a porthole. A partition 40 may comprise several openings 43, not all of which necessarily form an emergency exit 44, as shown in FIGS. 2 and 3. An opening 43 not forming an emergency exit 44 is closed by a fixed panel 49.
[0057] The ejection handle(s) 46 usually allow ejection of the movable panel 45 from the structure 4L. The ejected panel 45 thus frees the opening 43. Within a vehicle, a passenger or a member of the crew of the vehicle 10 can then pass through the opening 43 in order to exit the vehicle 10. For example, the panel 45 can be attached to the structure 41 by usual fastening devices, possibly reversible. Such fastening devices comprise, for example, pins each penetrating into an orifice of the panel 45 and into an orifice of the structure 2, each pin being secured to a cable capable of pulling on the respective pin to make it come out of at least one of said orifices, the ejection handle making it possible to act on this cable.
[0058] The partition 40 comprises an assistance device 1 to facilitate the evacuation of people through the emergency exit 44. The assistance device 1 comprises a circuit electrical circuit 4, an electrical power supply device 3 electrically supplying the electrical circuit 4, as well as light emitters 2 electrically connected to the electrical circuit 4. The light emitters 2 emit light when the electrical circuit 4 is electrically supplied by the electrical power supply device 3.
[0059] In particular, the electrical power supply device 3 may comprise an electric battery connected to a direct / alternating converter or an alternating electric current generator. In this way, the electrical power supply device 3 of the assistance device 1 is autonomous and independent of a centralized power supply of the vehicle 10, which may no longer function in the event of an accident of the vehicle 10.
[0060] Furthermore, the light emitters 2 comprise at least one first emitter 21 and at least one second emitter 22. The first emitter(s) 21 emit a first light of a first color and are arranged around the opening 43 so as to at least partially frame this opening 43 and the panel 45. The second emitter(s) 22 emit a second light of a second color distinct from the first color and are arranged near one or more ejection handles 46 so as to indicate its position or their positions.
[0061] In this way, when the light emitters 2 are electrically powered and emit light, individuals can see the emitted lights, including when visibility conditions are poor, for example in the presence of smoke, water or darkness. These individuals can then evaluate on the one hand the position of an emergency exit 44, and on the other hand the position of an ejection handle 46. These individuals can thus go quickly and directly to this emergency exit 44, and to the ejection handle 46 to eject the panel 45 in order to exit through the opening 43 of the partition 40.
[0062] The electrical power supply device 3 can electrically power the electrical circuit 4 and therefore the light emitters 2, for example following an accident of a vehicle 10. A switch or a contactor (not shown) can for example connect the electrical power supply device 3 and the electrical circuit 4. The switch can be manually operated by an individual, for example a passenger or a crew member of a vehicle. The contactor can be connected to one or more sensors causing the contactor to switch under predetermined conditions. Such sensors can for example comprise a shock detector, an accelerometer capable of detecting a strong deceleration or an immersion sensor.
[0063] According to a first embodiment shown in [Fig. 1], said at least one first emitter 21 extends continuously over a line surrounding the panel 45, so as to emit the first light in a substantially continuous manner to thus visually frame almost the majority of the panel 45.
[0064] According to this first embodiment, said at least one second transmitter 22 is arranged between two ends of said at least one first emitter 21 so that the first light and the second light are visually continuous. Said at least one second emitter 22 is arranged opposite the ejection handle 46 so as to clearly indicate its position.
[0065] Said at least one first emitter 21 and said at least one second emitter 22 thus respectively emit the first light and the second light one after the other, these being visually continuous to jointly form a light strip. Said at least one first emitter 21 may comprise one or more adjacent first emitters 22. Similarly, said at least one second emitter 22 may comprise one or more adjacent second emitters 22.
[0066] According to a second embodiment shown in [Fig. 2], the assistance device 1 comprises several first emitters 21 and several second emitters 22 arranged continuously and alternately around the opening 43. For example, the assistance device 1 comprises two first sections 71, 72 provided with first emitters 21 and two second sections 73, 74 provided with second emitters 22. Each first section 71, 72 then extends between two second sections 73, 74, and each second section 73, 74 then extends between two first sections 71, 72.
[0067] The two second sections 73, 74 are arranged opposite two ejection handles 46 respectively.
[0068] According to a third embodiment shown in [Fig. 3], a first emitter 21 comprises a main section 75 which completely frames the opening 43 and the panel 45. The first light is emitted in a substantially continuous manner, thus visually framing the entirety of the emergency exit 44.
[0069] According to this third embodiment, said at least one second emitter 22 has a secondary section 76, 77 which signals or even surrounds an ejection handle 46 and emits the second light substantially continuously.
[0070] The secondary sections 76, 77 may be electrically connected to the main section 75, by an electrical connection or by one or more light emitters 2 covered with a masking 5 blocking all or part of the emitted light. In this case, it is a total masking 51, locally blocking all the light likely to be emitted between the main section 75 and the secondary sections 76, 77.
[0071] The assistance device 1 may also comprise a masking 5 arranged partially around the opening 43, on a part of said at least one second emitter 22 as shown in [Fig. 1]. This masking 5 is, according to this example, a partial masking 52 which can form one or more symbols, so as to form, for example, a word such as “EXIT” as shown in [Fig. 1].
[0072] The partial masking 52 can directly represent the word, which then appears in black color for example, surrounded by the second light as shown in [Fig.l]. The partial masking 52 can alternatively mask the outline of the word, which then appears in the second color as shown in [Fig.3].
[0073] Such masking 5 may also be arranged on a part of said at least one first emitter 21.
[0074] Whatever the embodiment, the assistance device 1 may comprise at least one third emitter 23 emitting a third light and a partial masking 52 representing one or more symbols forming for example a word, as shown in [Fig. 3]. The third light may be of the first color or the second color, or of a color distinct from the first color and the second color.
[0075] Said at least one third emitter 23 is offset from the opening 43 as well as from the first emitter(s) 21 and from the second emitter(s) 22. The third light thus does not frame the emergency exit 44 and does not indicate the position of the ejection handle 46.
[0076] Said at least one third transmitter 23 can be electrically connected to said at least one first transmitter 21 by an electrical connection. Alternatively, said at least one third transmitter 23 can be directly connected to said at least one first transmitter 21, a total masking 51 covering over a limited area said at least one third transmitter 23 between said at least one first transmitter 21 and the partial masking 52. In this way, the word displayed by said at least one third transmitter 23 is visually isolated from said at least one first transmitter 21 and from said at least one second transmitter 22.
[0077] According to the embodiments shown in Figures 1 to 3, the light emitters 2 are arranged only inside a vehicle 10 to be visible to the passengers and crew members of the vehicle 10 as shown in Figures 1, 2 and 3. Alternatively or in a complementary manner, light emitters 2 can be arranged outside the vehicle 10 in order to be visible to a rescue team working on the vehicle 10, as shown in [Fig.4].
[0078] Furthermore, whatever the embodiment, the light emitters 2 as well as at least partially the electrical circuit 4 can be arranged on the structure 41 as described previously or on a light frame 30 fixed on the structure 41 around the opening 43 and the panel 45 as shown in [Fig. 2]. The light frame 30 comprises a support 31 on which the light emitters 2 as well as at least partially the electrical circuit 4 are arranged.
[0079] The support 31 may have a shape and relief complementary to a shape and relief of the structure 41 around the opening 43 and the panel 45. The support 31, and consequently the light frame 30, can be rigid or flexible. In this way, the support 31 adapts perfectly to the structure 41. The light frame 30 can thus be manufactured and prepared outside the vehicle 10, and integrated easily and quickly on the structure 41 of the partition 40.
[0080] The support 31 can be effectively fixed to the structure 41, for example by gluing, riveting, screwing or any other usual fixing means.
[0081] The light frame 30 may be electrically connected to the power supply device 3. Alternatively, the light frame 30 may comprise the power supply device 3.
[0082] Furthermore, the light emitters 2 may comprise, in the usual manner, light-emitting diodes or any other equivalent device generating light. Alternatively, the light emitters 2 may comprise one or more optical fibers connected to one or more light generators. For example, said at least one first emitter 21 may comprise a first optical fiber connected to a first light generator and said at least one second emitter 22 may comprise a second optical fiber connected to a second light generator.
[0083] Alternatively, the light emitters 2 may comprise electroluminescent paints or electroluminescent inks.
[0084] In this case, the light emitters 2 may comprise a superposition of layers including at least one conductive layer, at least one electrically insulating layer, a layer of electroluminescent paint or electroluminescent ink, and at least one transparent or translucent protective layer. The light emitters 2 may also comprise a masking layer.
[0085] In fact, when the electrical circuit 4 is electrically powered by the electrical power supply device 3, the electroluminescent pigments of the paint or electroluminescent ink of these light emitters 2 emit light.
[0086] An example of such a superposition of layers forming an electroluminescent paint is shown in [Fig. 5]. Such a superposition of layers can be applied to the structure 41 of the partition 40 or to the support 31 of the luminous frame 30. This structure 41 or this support 31 can be flat or on the contrary include asperities, hollows, and / or bumps, as shown in [Fig. 5].
[0087] An initial electrically insulating layer, forming a substrate 66, may be applied to the structure 41 or to the support 31, in particular if the structure 41 or the support 31 is at least partially electrically conductive. This substrate 66 has a sufficient thickness to avoid, for example, current leaks or electrical breakdown with the support 31 or the structure 4L. In the case where the support 31 or the structure 41 is electrically non-conductive, this substrate 66 may not be necessary. The support 31 may for example comprise a film with adhesive.
[0088] Next, a lower conductive layer 65 made of a material with low electrical resistance and therefore highly electrically conductive is applied, in particular to the surface to be illuminated. This lower conductive layer 65 allows an electric current to be distributed over the entire surface to be illuminated.
[0089] Then, a dielectric layer 53, namely electrically insulating, is applied to the lower conductive layer 65 to avoid any risk of short circuit. A luminous layer 54, comprising the electroluminescent paint or ink, is applied to the dielectric layer 53. This luminous layer 54 notably comprises the pigments capable of emitting light.
[0090] An intermediate conductive layer 55 is partially applied to the luminous layer 54. This intermediate conductive layer 55 is, like the lower conductive layer 65, made of a material with low electrical resistance and therefore highly electrically conductive. The intermediate conductive layer 55 and the lower conductive layer 65 can be made with the same material. This intermediate conductive layer 55 is applied in the form of a narrow strip on the periphery of the luminous layer 54 to very partially cover this luminous layer 54 so as not to mask it and therefore not to block the emission of light. In addition, the intermediate conductive layer 55 must not be positioned at the right angle of the lower conductive layer 65 as shown in [Fig.4].
[0091] An upper conductive layer 56 is applied to the luminous layer 54 and the intermediate conductive layer 55, being in contact with the intermediate conductive layer 55. The upper conductive layer 56 is made of conductive material to allow good circulation and distribution of the electric current in the different layers. This upper conductive layer 56 is translucent or transparent to allow the light emitted by the luminous layer 54 to be visible.
[0092] A transparent or translucent dielectric upper insulating layer 57 is applied. This upper insulating layer 57 encapsulates the electric current in the lower layers to protect against electric shocks. It also protects the different layers from scratches, contamination and ultraviolet rays in particular, while allowing the passage of light emitted by the luminous layer 54.
[0093] If necessary, a masking layer 58 can be applied to the upper insulating layer 57 in the area(s) to be masked, i.e. where no light is to be emitted.
[0094] Finally, depending on the regulatory requirements or the environment in which the partition 40 is used, a protective layer 59 may be applied. This protective layer 59 is transparent or translucent and may, for example, ensure watertightness of the superposition of the layers. This protective layer protection 59 can also provide resistance to fire or high temperatures, for example to reduce the spread of a fire. This protective layer 59 can, for example, comprise a coating containing a polyurethane.
[0095] Finally, a finishing layer 60 can be applied to the protective layer 59. This finishing layer 60 is transparent or translucent and has a mainly aesthetic function by covering the entire structure 41 or the support 31.
[0096] Among this superposition of layers, the upper conductive layer 56 and the lower conductive layer 65 are respectively connected to the two terminals of the electrical power supply device 3. In addition, the upper conductive layer 56 not being positioned at the right angle of the lower conductive layer 65, a good distribution of the electric current or of the induced magnetic field is obtained, in the luminous layer 54.
[0097] Under the action of this electric current, electrons can jump between the upper conductive layer 56 and the lower conductive layer 65. By crossing the luminous layer 54, the electrons excite the pigments which emit photons when they return to the equilibrium state, thus generating light which then passes through the upper layers, namely from the upper conductive layer 56 to the upper insulating layer 57, or even to the protective layer 59 and / or the finishing layer 60. However, in the areas where the superposition of layers includes the masking layer 58, the light is stopped by this masking layer 58.
[0098] Naturally, the present invention is subject to numerous variations as to its implementation. Although several embodiments have been described, it is understood that it is not conceivable to exhaustively identify all possible modes. It is of course conceivable to replace a means described by an equivalent means without departing from the scope of the present invention and the claims.
