     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0027]     Some preferred embodiments are shown by way of example and not limitation in the accompanying figures. In this regard,  FIG. 1  shows illustrative components of a rotary sprinkler device that can be employed in some illustrative embodiments.  FIG. 2  shows an illustrative embodiment wherein components shown in  FIG. 1  are contained inside of a frog-shaped enclosure. In  FIG. 2 , the rotary sprinkler device is depicted in a pop-up state extending out of said enclosure. When not in use (such as, e.g., for discharging water), the narrower upper element A of the sprinkler preferably retracts substantially or entirely within the wider lower element B of the sprinkler. As shown in  FIG. 2 , water can flow into the enclosure via an inflow (such as, e.g., a common garden hose or other inflow means) and connect to the sprinkler. In other embodiments, the sprinkler can contain a refillable self-contained source of water. In some embodiments the self-contained source of water can be refilled manually and/or by other inflow means. In some embodiments, the enclosure can conveniently include a timer valve therein. Among other things, the enclosure may serve to protect the internal components. In other embodiments, the timer valve can be located externally to the enclosure (such as, e.g., proximate another end of a hose, such as, e.g., adjacent a spigot, which may be conveniently located at or near a dwelling or the like for resetting of timer or the like).  
         [0028]     In some embodiments, the sprinkler can be controlled by a switch which is able to turn the sprinkler&#39;s power on/off. In some embodiments, the switch can be physically attached to the enclosure (such as, e.g., on the enclosure or in the enclosure). In other preferred embodiments, the switch can be located externally to the enclosure (such as, e.g., including a wall switch inside or outside a dwelling). In further preferred embodiments, the switch can be located on a remote device (such as, e.g. a key chain).  
         [0029]     In preferred embodiments, the pop-up and release is caused by water pressure. In some embodiments the pressure is turned on/off through the use of a valve. In preferred embodiments, the valve is a controlled valve (such as, e.g., via a timer mechanism). In some embodiments, the controlled valve can be located internally within the enclosure of the discharge unit and/or can be located externally to the enclosure.  
         [0030]     In some embodiments, the sprinkler can include an integral sprinkler stake (not shown) connected thereto (i.e., wherein the stake can be used to penetrate a ground surface for added stability). In some instances, the enclosure can be configured to have at least one bottom opening to enable the stake to pass there-through. In some embodiments, a stake can be eliminated and/or some embodiments can have one or more stake(s) that is removable. Accordingly, some stake-less configurations may enable placement on a hard surface such as, e.g., a patio, a poolside, a wall, a rock or the like. In some embodiments, a non-slip surface can be attached to the base of the enclosure, such as, e.g., a high friction rubber. In some embodiments, one or more holes can be formed in the enclosure base to receive stakes that can optionally be inserted therein. In some embodiments, stakes could, e.g., be stored inside the enclosure and employed as desired depending on location of use.  
         [0031]     In some embodiments, the enclosure can be made of a plastic material. Preferably, the plastic material is made to have a glossy outer surface. In some embodiments, the enclosure can be made with other materials, such as, e.g., ceramic, metal (such as, e.g., copper, brass, aluminum, iron, stainless steel, etc.). In some embodiments, the outer enclosure can be colored, coated, or the like. Preferably, a plurality of enclosure colors are offered such that users can select a color to best suit their environment. Preferably, colors of the enclosure are designed to blend into a natural environment, such as, e.g., reds, oranges, yellows, greens, and/or the like.  
         [0032]      FIG. 3  shows an illustrative embodiment with a rotary discharge device in a retracted or off position. As shown, the pop-up device is preferably entirely inside the enclosure when not in use. In this manner, the enclosure can also service another utilitarian purpose as an ornamental statue or the like.  
         [0033]     As shown in  FIG. 4 , in use the pop-up device can extend from the enclosure and discharge water.  FIG. 4 , shows water being discharged in a narrower spray manner. On the other hand,  FIG. 5 , shows water being discharged in a wider spray manner. It should be appreciated that various manners of spraying could be employed, such as, e.g., a laminar-flow discharge, a turbulent-flow discharge, spraying in a stream-like manner, misting, sprinkling and/or the like. In this disclosure, the terminology spray, spraying, sprinkling and sprinkler are intended to and is defined herein as identifying water discharge in any desired manner.  
         [0034]     In some embodiments, the discharge from the unit involves a discharge of water having a substantial percentage (such as, e.g., more than about ⅓, in some embodiments, or more than about ½ in other embodiments, or even more than about ⅔ in other embodiments) of which has particle sizes of under about 10,000 microns, such that the discharge involves a substantial percentage of drops. In some embodiments, the discharge from the unit involves a discharge of water having a substantial percentage (such as, e.g., more than about ⅓, in some embodiments, or more than about ½ in other embodiments, or even more than about ⅔ in other embodiments) of which has particle sizes of under about 3,000 microns, or, in some other preferred embodiments under about 1,000 microns, or, in some other embodiments, under about 500 microns, or, in some other embodiments, under about 100 microns, or, in some other embodiments, under about 5-10 microns. In this regard, the following TABLE I shows some illustrative sizes for reference.  
                             TABLE I                       (Illustrative Approximate Water Particle       Sizes Versus Moisture Conditions)                                      5 microns   Fog            100 microns   Mist            500 microns   Light rain           1000 microns   Moderate rain           3000 microns   Heavy rain                      
 
         [0035]     In some embodiments, a substantial amount of the water or substantially all of the water is discharged in a mist. Among other things, due to their microscopic size (e.g., below about 100 microns, such as, e.g., between about 80 and 100 microns), the water drops are atomized droplets that remain suspended and mimic the flooding characteristics of a gas, moving along with wind-flow, etc., and freely moving around obstructions.  
         [0036]     In some embodiments, the misting performs evaporative cooling. In this regard, evaporative cooling occurs when the misted water absorbs heat energy, which changes it into a water vapor. Generally speaking, every gallon of water that changes from a liquid into vapor absorbs more than about 8,000 BTU&#39;s of heat energy. This cooling process is especially effective when the relative humidity is lowest. However, evaporative cooling works generally everywhere. Notably, during the middle (i.e., hottest part) of the day, the relative humidity is lower. In some exemplary conditions, ambient air can be lowered or cooled down by about 3 degrees (i.e., wet bulb temperature).  
         [0037]     While in many embodiments, the water discharged is forced through the discharge unit based on the pressure of the supplied water—e.g., based on the water pressure supplied via water utility lines (e.g., often this is between about 20 to 60 PSI, or, most often about 30-50 or generally about 40 PSI). However, in some embodiments, the water is discharged using an additional pumping mechanism, which may, in some embodiments be mounted within the enclosure of the device, or which may, in other embodiments, be mounted distant from the enclosure of the device, such as, e.g., along a supply line to the device. In some embodiments, the pump may be used to achieve a substantially higher pressure, such as, e.g., pressures within ranges of, e.g. over 75 PSI, or 100 PSI (or even, e.g., over 500 PSI, or 800 PSI, or 1000 PSI) to facilitate, e.g., mist generation.  
         [0038]     From the moment a spray droplet leaves the spray nozzle it is subject to evaporation. The life of a drop of water is generally proportional to the square of its diameter. For example, a 50 micron water drop that is at 20° C. and at a relative humidity of about 50% may have a lifespan of about 4 seconds. On the other hand, a 100 micron drop may have a lifespan of about 16 seconds. After a particle or drop is discharged, it may decrease in size due to evaporation and, thus, as it decreases in size have a tendency to drift and be carried along in the ambient air or wind. In general, particles of larger than about 500 microns will experience little drift.  
         [0039]     In some illustrative an non-limiting embodiments, the discharge device can be used to apply a mist or the like to, by way of example, help with a) cleaning air (e.g., to limit air-borne allergens), b) odor control, c) fire retardation, d) vegetation humidification (e.g., within green houses), e) cooling of individuals (e.g., at public locations, such as, e.g., pools, restaurants, sports or athletic events, health clubs, etc., and/or at private locations), f) animal treatment (e.g., within zoos, etc.). In some embodiments, discharge may be applied indoors (e.g., for humidity, cooling and/or the like) purposes or may be applied outdoors.  
         [0040]     In preferred embodiments the discharge device can employ interchangeable nozzles. In some embodiments the nozzle trajectory can be changed by adjusting trajectory angle.  
         [0041]      FIG. 6  shows an illustrative enclosure having a convenient removable lid and a base. When the lid is removed, a user can conveniently access the interior of the enclosure (as shown). The embodiment shown in  FIG. 6  includes a small diameter discharge tube. This type of tube can be used in, e.g., embodiments similar to that of the above-noted co-pending patent application incorporated herein by reference. This type of device can be readily upgraded, e.g., modified, so as to include a pop-up discharge structure by, e.g., removing the tube and connecting a water discharge device, such as, e.g., shown in  FIG. 2 .  
         [0042]      FIG. 7 (A) is a schematic side view demonstrating an illustrative spray-type of discharge. In this illustrative embodiment, the discharge device  10  (which can be constructed in accordance with any of the embodiments described herein) is adapted to provide a spray that is directed generally in a first direction D 1 . In some embodiments, as described herein, the discharge can have a substantially laminar flow (e.g., at least after exiting the unit), a substantially turbulent flow, an intermittent flow, a substantially continuous flow, a sprinkling of droplets or water particles and/or the like.  
         [0043]      FIG. 7 (B) is a schematic side view demonstrating an illustrative mist-type of discharge. In this illustrative embodiment, the discharge device  10  (which can also be constructed in accordance with any of the embodiments described herein) is adapted to provide a spray that is directed generally upward (see, e.g., arrows). However, as shown by the wavy lines, the mist particles are, in this embodiment, sufficiently small so as to effectively float along with ambient airflow patterns.  
         [0044]      FIG. 7 (C) is a schematic side view showing some illustrative embodiments in which the discharge unit includes its own supply of water or other liquid. In this regard, in this illustrative embodiment the device  10  includes an inner receptacle  20  that can be filled with water. In some illustrative embodiments, the top of the enclosure can be removed (or a door or the like can be opened) and a cap  21  can be removed such that water can be filled into the receptacle. In this illustrative embodiment, the top of the enclosure T is shown as removably supported on the base of the enclosure B at dashed line DL. To fill the unit, the user can lift the top, and place water into the device. In embodiments that can operate based upon water from an internal water supply, a pump P is provided that can enable water to flow from the supply  20  through the spray device S (which can be, e.g., like that in any embodiment described herein and/or incorporated herein by reference). In some embodiments, the device  10  further includes a controller C, which can include, e.g., hardware, firmware and/or software to control operation of the pump P and/or a valve (not shown) for opening and/or closing flow through the spray device S. In the preferred embodiments, the pump and/or the controller is electrically powered, such as, e.g., via electrical power supplied via a power chord EP that can be plugged into a standard electrical outlet and/or via a battery (not shown) that may be contained within the enclosure and/or the like. In some embodiments, the system can include a receiver TR for receiving communication signals from a remote device in order to control the operation of the controller C, the pump P and/or a valve (not shown). In some embodiments, the receiver receives electromagnetic signals that are transmitted wirelessly from a transmitter (not shown) at a remote location. In some embodiments, the transmitter sends a radio signal that is received by the receiver. In some embodiments, the controller C includes a timing module by which a user can set a time of operation of the device. In some embodiments, the receiver TR and the transmitter (not shown) are both transceivers such that they can both send and receive information. In this manner, for example, the transmitter can receive information from the receiver, such as, e.g., related to the status of the device (e.g., water content remaining, time remaining and/or the like).  
         [0045]      FIG. 7 (D) is a schematic side view showing some illustrative embodiments in which the discharge unit includes a storage area SA for interchangeable replacement nozzles. For example, the nozzles may include various discharge orifice sizes, shapes, and/or the like, such that, e.g., a user can switch nozzles to achieved desired flow characteristics, such as, e.g., misting, sprinkling, rotation, adjustability and/or other possible variation. As with the embodiment shown in  FIG. 7 (C), the storage area is preferably contained inside of the device  10  and accessible by removing the top T of the enclosure (or a door or the like) to provide access to the interior compartment.  
         [0046]      FIG. 8 (A) is a schematic diagram showing some illustrative embodiments utilizing remote control devices. It is contemplated that any of the embodiments described herein and/or incorporated by reference herein (such as, e.g., in the above-noted pending non-provisional patent application incorporated herein by reference) can incorporate similar remote control devices. As shown, the device  10  can include a receiver TR (which may be, e.g., similar to the receiver TR described above) that can operate to receive signals to control the operation of the device  10  and, in some embodiments, to send signals indicative of, e.g., the operation of the device  10 . In some embodiments, the system can include one or more transmitter (which may be, e.g., similar to the transmitter described above). In the illustrated embodiment, a first transmitter T 1  and/or a second transmitter T 2  can be employed. In this illustrative example, the transmitter T 1  is shown fixedly attached (such as, e.g., mounted via screws, bolts, glue and/or the like) to a remote structure (such as, e.g., a building, a dwelling, a house, a garage, a post, a tree and/or the like). On the other hand, the transmitter T 2  is shown unattached to any device and is, most preferably, portable. For example, the transmitter T 2  can in some embodiments, be less than a few inches long. In some preferred embodiments, as shown in dashed lines, the transmitter T 2  can include an key holding device, such as, e.g., a common key ring for supporting keys. In use, the transmitter T 1  and/or the transmitter T 2  can be used to remotely control the operation of the device  10 .  
         [0047]      FIG. 8 (A) also shows another optional device EC that can be employed in some embodiments. The device EC is a device for determining, evaluating and/or sensing environmental conditions. For example, in some embodiments, the EC can include a water level sensor (see, e.g., the above-noted co-pending non-provisional application) (such as, e.g., to initiate use based on water level). In some other embodiments, the EC can include a temperature and/or humidity level sensor (such as, e.g., to initiate use based on ambient temperature and/or humidity level). In some other embodiments, the EC can include a motion detector (such as, e.g., to initiate use based on presence of a user). In some other embodiments, the EC can include a soil moisture and/or soil condition indicator (such as, e.g., to initiate use based on soil conditions). In some other embodiments, the EC can include a light detector (such as, e.g., to initiate use based on presence and/or absence of a certain level of light). While the EC may be remotely situated with respect to the device  10 , in some embodiments an EC can be incorporated into the device  10 . As shown, in some embodiments, the EC is adapted to transmit and/or to receive signals to a transmitter T 1  and/or T 2  and/or to the receiver TR in order to allow the EC to report conditions to the user (i.e., the operator of the transmitter), to provide for control the device  10  based, at least in part, on an output of the EC (such as, e.g., to control the time of discharge based on ambient temperature and/or humidity). In some embodiments, the EC can itself automatically transmit signals to effect control of the device  10 , such as, e.g., to automatically maintain a certain humidity level, water level, temperature level and/or the like. In some embodiments, the EC could also be integrated within a transmitter T 1  and/or T 2 . As discussed above, the receiver TR and the transmitters T 1  and/or T 2  could all actually be transceivers in some embodiments.  
         [0048]      FIG. 8 (B) is a schematic diagram showing some illustrative embodiments in which a control unit CU (which includes a controller that controls the operation of a valve, pump and/or the like associated with the control unit, such as, e.g., by enabling selection and/or control of on/off operation of a flow control valve, a pump and/or the like) can be situated either inside the device  10  (as shown in dashed lines) or outside of the device. In the illustrated embodiment, the control unit CU is shown as mounted proximate either an inner end (e.g., inside the device  10 ) of a water supply conduit SC (which can be, e.g., in some embodiments a common garden hose or the like) and/or on a distal end (e.g., remote from the device  10 ) of the supply conduit SC. In some embodiments, the control unit CU can include a user interface (such as, e.g., keys, buttons, displays and/or the like) for user operation and control. In some embodiments, a remote transmitter (which can be, e.g., a transceiver) T 3  can be employed that can remotely control the control unit, such as, e.g., via the transmission or electromagnetic signals to the control unit. In the illustrated embodiment, the control unit at the distal end of the supply conduit is connected to the spigot SP (e.g., or like water supply source) such that in some embodiments the spigot can be opened and the control unit can be used to further control flow through the device  10 . Similarly, in instances when the control unit CU is located inside the device  10 , the supply conduit SC can be connected in fluid communication with a spigot SP and/or the like.  
         [0049]      FIG. 9  is a schematic flow diagram showing an illustrative process according to some preferred embodiments of the invention. In the preferred embodiments, the method enables a water discharge device to have a substantially ornamental configuration with the water discharge outlet in a substantially unexposed condition. In this manner, the discharge outlet can be protected during use and/or can avoid unsightly exposure that detracts from the ornamental appearance of the device. However, during use, the outlet can be exposed for enhanced discharge capabilities.  
         [0050]     With reference to  FIG. 9 , the preferred method includes a first step at which the device is in an non-use condition with the outlet substantially un-exposed. Then, at a second step, the device is turned on or flow is initiated. To do this, e.g., a valve may be opened, a pump may be turned on and/or flow may otherwise be initiated. Then, at a third step, the outlet is exposed. In preferred embodiments, the water pressure caused by water flow will cause the discharge outlet to become exposed (such as, e.g., by raising the discharge outlet). In some embodiments, other means can be used to raise the discharge outlet during use, such as, e.g., by another mechanism, such as, e.g., an electronic motor, a solenoid and/or the like. Then, at a fourth step, the discharge continues with the discharge outlet in an exposed condition. Preferably, in this fourth step, the water pressure continues to maintain the discharge outlet in a raised condition. Then, at a fifth step, the device is turned off, such as, e.g., by shutting a valve, turning off a pump and/or otherwise stopping water flow. Then, in a sixth step, the outlet is caused to be substantially un-exposed. In preferred embodiments, the water pressure caused by water flow will cause the discharge outlet to become substantially un-exposed (such as, e.g., by lowering the discharge outlet). In some embodiments, other means can be used to lower the discharge outlet during use, such as, e.g., by another mechanism, such as, e.g., an electronic motor, a solenoid and/or the like. Then, at a seventh step, the device will return to the original non-use condition, in which the outlet is substantially unexposed.  
         [0051]     FIGS.  10 (A) and  10 (B) are schematic side views showing illustrative embodiments in which the relative movement of the discharge device and the enclosure is effected by movement of the enclosure (i.e., such that the discharge device effectively pops-out due to movement of the enclosure). In this disclosure, the terminology pop-out does not require movement of the discharge device, but relates to the fact that the discharge device is exposed by some form of relative movement between the enclosure and the discharge device. Specifically, in the device shown in  FIG. 10 (A), a top portion TOP of the device  10  is moved up-and-down in the direction of the double-sided arrows such as to expose the water discharge outlet in the raised state (shown in solid lines) and to cover the water discharge outlet in the lowered state (shown in dashed lines). Similarly, in the device shown in  FIG. 10 (B), a small portion BK (such as, e.g., a lower jaw, mandible or beak representative portion) of the enclosures is moved (such as, e.g., in the direction of the double-sided arrows shown in the illustrative example) so as to expose and/or cover the water discharge outlet. In this manner, the water discharge outlet, under the language as defined herein, effectively “pops-out” for discharge usage and is covered during non-use.  
         [0052]      FIG. 11  is a somewhat schematic side view showing illustrative features of a pop-up discharge device according to some illustrative and non-limiting embodiments of the invention. In this illustrative example, a discharge device  10  is connected to a supply conduit SC of water (such as, e.g., a garden hose and/or the like). The supply conduit SC preferably includes a threaded end that is threadedly engaged within a mating threaded socket SK within the device  10 . Water that enters the device then passes via a control unit (which can include, e.g., a timer and an on/off valve that is controlled by the timer). During use, water is released by the opening of the valve within the control unit so as to flow towards the discharge spray device S. In this illustrative embodiment, the spray device S includes an outer tube S 2  that receives (e.g., in a telescoping manner) an inner tube S 1 . An annular seal ring SL is preferably provided to maintain a water seal between the tubes S 1  and S 2 . When water enters the tube S 2  it creates a pressure against the bottom of the portion GN. This pressure causes the inner tube S 1  to raise upward to expose the nozzle which otherwise is maintained within the enclosure (shown in dashed lines). In addition, the portion GN can include gears and/or a turbine, turning vanes and/or the like that causes the tube S 1  to rotate. In this manner, the discharge through the outlet of the nozzle can be directed in a generally circular pattern. In addition, in some embodiments, the mechanism GN be configured to cause the nozzle to rotate and/or to oscillate back-and-forth about a portion or arc of less than 360 degrees, such as, e.g., 270 degrees, 180 degrees, 90 degrees and/or the like. In this illustrative embodiment, a replaceable nozzle N can be employed that is threadedly received within a corresponding female threaded socket at the top of the tube S 1 . In this manner, the nozzle can be readily interchanged and/or replaced as desired, such as, e.g., to switch between spraying, misting and/or the like.  
         [0053]      FIG. 12 (A) is a perspective view of an illustrative angularly adjustable discharge nozzle and  FIG. 12 (B) is a side view of another illustrative angularly adjustable discharge nozzle. In this regard, in some embodiments, the angular trajectory (e.g., the angle of discharge with respect to the horizontal and/or with respect to the ground surface on which the device  10  is supported) can be varied. While a variety of angular adjustment mechanisms can be employed, such as, e.g., pivoting nozzle support mechanisms, bendable and/or malleable nozzle conduits and/or the like, these illustrated embodiment show some illustrative constructions. In these illustrated examples, the nozzle can include two sections NT and NB. These sections can include a common inner passage and can be rotatably attached to one another so as to rotate respectively to one another around an inclined axis IA. In this manner, as the member NT is rotated relative to the member NB, the angular position of the discharge outlet will vary accordingly. In the illustrative example shown in  FIG. 12 (A), the discharge outlet is depicted on an outer end of the nozzle, while in the example shown in  FIG. 12 (B), the discharge outlet is depicted on the side of the nozzle. Once again, these are merely some illustrative examples.  
         [0054]     It is contemplated that a pop-out water discharge device could also be used to perform one or more of the functions described in said co-pending non-provisional patent application entitled WATER BODY (e.g., POOL) WATER REPLENISHMENT SYSTEM AND METHOD.
