     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a midge/mosquito trap system and more particularly pertains to attracting and killing midges and mosquitos and a wide variety of other flying insects in a safe, convenient and economical manner. 
     2. Description of the Prior Art 
     The use of insect traps of known designs and configurations is known in the prior art. More specifically, insect traps of known designs and configurations previously devised and utilized for the purpose of trapping insects through known methods and apparatuses are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements. 
     While the prior art devices fulfill their respective, particular objectives and requirements, they do not describe midge/mosquito trap system that allows attracting and killing midges and mosquitos and a wide variety of other flying insects in a safe, convenient and economical manner. 
     In this respect, the midge/mosquito trap system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of attracting and killing midges and mosquitos and a wide variety of other flying insects in a safe, convenient and economical manner. 
     Therefore, it can be appreciated that there exists a continuing need for a new and improved midge/mosquito trap system which can be used for attracting and killing midges and mosquitos and a wide variety of other flying insects in a safe, convenient and economical manner. In this regard, the present invention substantially fulfills this need.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to  FIG. 1  thereof, the preferred embodiment of the new and improved midge/mosquito trap system embodying the principles and concepts of the present invention and generally designated by the reference numeral  10  will be described. 
     The present invention, the midge/mosquito trap system  10  is comprised of a plurality of components. Such components in their broadest context include a chamber, a fan, a carbon dioxide tank and a solenoid. Such components are individually configured and correlated with respect to each other so as to attain the desired objective. 
     Referring more specially to the drawings, my improved mosquito killing system is generally designated by reference numeral  20 . System  20  attracts mosquitoes  22  by actively projecting multiple infrared heat gradients and&#39;pressure differentials coupled with a wide variety of aromatics that simulate animal body heat and breathing. 
     System  20  comprises an elongated, generally parallelepiped housing  25  disposed upon a convenient supporting surface  26  (FIG.  1 ). The housing comprises a rectangular support base  30  and a spaced apart, truncated pyramidal roof  40  ( FIGS. 1-2 ). The roof closes the tower interior. A switch  32  and photoelectric sensor system  34  control system operation, as discussed hereinafter. A pilot light  42  physically protrudes form roof  40  to indicate the operational status of system  20 . 
     The roof  40  is secured to an internal heating tower  50  extending between the base  30  and the roof  40 . A conventional bolt  45  extends through roof  40  to mate with a conventional nut  40 . A cross member  48  secures roof  40  to tower  50  and base  30 . 
     The tower  50  conducts air drawn into the base  30  into the upper portion of the housing and then forcefully projects it outwardly. A vertically oriented electrocution grid  60  is fixed to the outer perimeter of the tower  50 . An outermost, safety wire mesh guard  70  surrounds the tower. It extends between the base and the roof to prevent accidental contact with the interior electrocution grid  60  or other internal components. An annular region  71  is defined between the guard  70  and tower  50 ; this region is traversed by mosquitoes  22 ,  22 A ( FIG. 1 ) passing through the guard. Several spaced apart terminal loops  72  and conventional screws  74  removably secure guard  70  to the base  30  and roof  40 . The wire mesh comprises several vertically aligned, parallel, spaced apart stringers  76  reinforced by several parallel, regularly spaced apart horizontal cross members  78 . 
     The base  30  preferably comprises a hollow, parallelepiped casing  80  ( FIGS. 2 ,  7 - 8 ) that supports the housing  35 . The casing  80  rests on plate  82 . Casing  80  is penetrated by a plurality of intake orifices  83  for first admitting air into the system in response to fan suction. These preferably slit-shaped orifices  83  are regularly spaced about the casing periphery  84  for admitting air into the system. One slit  83  exposes a moist wick  85  to the exterior of the device. A scent drawer  90  also penetrates casing  80 . 
     The scent drawer  90  contains gel  92  that simulates common smells attractive to mosquitoes or to the target insect. The gel  92  gradually releases pheromones (represented by dashed lines  98 ) into the casing interior  86  for mixture with the entering air currents (represented by dotted lines  108 ). Wick  85  supplies moisture (represented by dotted and dashed lines  88 ) to the casing interior, where it is mixed with the entering air currents  108 . Casing interior  86  serves as a mixing chamber where the entering air  108  is intermixed with aromatics  98  and moisture  88 . 
     An internal fan  100  forcefully draws air  108  through the slits  83  and into the casing  80 . Preferably, the fan  100  has a relatively low volumetric output rate, in the range of ten to twenty cubic feet per minute (cfm), most preferably fifteen cfm. As air  108  is suctioned into the apparatus it is turbulently mixed with released aromatics  98  and emitted moisture  88  in the casing interior  86 . Fan  100  is secured to plate  82  adjacent transformer  102 . Preferably, the fan blades  105  are positioned immediately adjacent the tower bottom  58 . Air forced upwardly by the fan is directly forced into the heating tower  50  and eventually rises to top  54 . The resultant tower air stream is represented generally by arrows  118  ( FIG. 8 ). 
     The tower  50  preferably comprises an elongated tubular conduit  110 , preferably with a rectangular cross-section. The external surface  112  of the conduit  110  is obscured by electrocution grid  60 . A plurality of spaced apart braces  64 ,  65 ,  66 ,  67  and  68  secure the electrocution grid to two elongated, vertically oriented parallel rods  62  and  63  that are parallel to the longitudinal axis of opposite tower corners  52  and  53 . Of course, tower  50  could be cylindrical or another configuration as long as vertical air flow through tower  50  remains. 
     An internal, perforated baffle  115  divides the tower  50  into adjacent, lower and upper tubular sections  120  and  130  respectively ( FIG. 8 ). Tower section  120  defines an enclosed heating chamber  125  The upper tower section  130  defines an adjacent dispersal chamber  135 . In effect the baffle  115  comprises a restrictor plate between the chambers that affects the internal tower airflow  118 . It establishes an internal pressure differential between the chambers. Because of the preferred baffle design, denser, warmer air in the lower chamber is at a higher pressure than air above. The tower air pressure differential, and the temperature and pressure gradients established with the preferred construction I have detailed are important. These synergistically enhance the ability of the system to emulate the infrared signature of a live, breathing animal that is attractive to insects. In other words, I have found that this arrangement produces infrared images that simulate the presence of breathing animals, including human beings, fowl and the like. 
     The lower tower section  120  houses an elongated, cylindrical, resistive electric heater  122  that warms air within the heating chamber. Baffle  115  restricts the upward airflow to ensure that the residence time of the air  118  in the lower section  120  is adequate to heat the air sufficiently (preferably to a temperature between 100 and 120 degrees Fahrenheit). Preferably, heater  122  centrally extends along the longitudinal axis of section  120  between bottom  58  baffle  115 . Heater  122  is supported at one end by a strut  124  extending across bottom  58  above fan  100 . The opposite end of heater  122  is supported by brace  115 . 
     This turbulent air  118  is heated as it travels past heater  122 . A thermostat  126  controls the operation of heater  122  by monitoring tower temperature. Thermostat  126  is preferably mounted adjacent baffle  115  with its thermostatic element in thermal contact with the tower. Of course, the extent to which the air is heated depends upon prevalent external environmental conditions, as will be discussed more thoroughly hereinafter. 
     Baffle  115  increases the internal tower pressure differential. As air  118  flows up conduit  110 , baffle  115  restricts its flow. Several holes  116  penetrate the plate  117  comprising baffle  115 . These holes  116  permit air  118  to eventually cross into top section  130 . Consequently, the pressure of the air (indicated by arrows  128 ) entering the upper section  130  is increased by the restriction of baffle  115 . Thus, heated air  128  both a higher temperature and a higher pressure than entering air  108 . 
     Air  128  entering the upper section  130  is eventually dispersed into housing  25  and the immediately surrounding area. As air  128  enters the upper section  130  from the bottom section  120 , it flows through a plurality of regularly spaced apart discharge orifices  132  penetrating the upper section walls  134 ,  135 ,  136  and  137  beneath the roof. The discharge orifices pass heated, slightly pressured air outwardly in small turbulent streams (as indicated by arrows  138 ). The air streams  138  emitted from the orifices into the housing are strongest within the interior annulus  71 . The multitude of air streams established thereby create the appearance of animal breathing. In addition there are thermal and pressure gradients surrounding the housing  25 . These gradients additionally simulate human breathing, and the resultant thermal pattern attracts mosquitoes who mistake it for the infrared signature of an animal, including a human being, fowl or the like. 
     Attracted mosquitoes  22  are electrocuted (i.e., mosquito  23  shown in  FIG. 3 ) when they approach the tower  50  by the electrocution grid  60  surrounding the exterior conduit surface  112 . The electrocution grid  60  comprises a vertically oriented wire network  150 . Multiple spaced apart electrically conductive stringers  152  extend downwardly from top brace  64  and main line  151  with corresponding spaced apart electrically conductive stringers  154  protruding upwardly from bottom braces  68  ( FIGS. 4 and 7A ). A plurality of staples  155  secure both main lines  151 ,  153  to respective braces  64  and  68 . 
     The downwardly oriented and upwardly oriented stringers  152  and  154  alternate. In other words, an upward stringer  154  extends between each downward stringer  152  ( FIG. 7A ). Whenever an object touches a downward and an upward stringer  152  and  154 , it creates a short circuit that electrifies the object, such as mosquito  23 . 
     After electrocution, the insects (i.e. mosquitoes) are generally disintegrated. Other remains generally fall toward the base  80  where they are typically swept away by winds, etc. However, when necessary, the middle braces  65 ,  66  and  67  may all be manually manipulated to clean the grid  60 . A set screw  69  normally retains the braces in place. Set screw  69  tightens against rod  62  or  63  to secure the brace  64 - 68 . Set screw  69  may be loosened to move braces  65 ,  66  or  67  upwardly or downwardly to clean stringers  152  and  154  as shown in  FIG. 6 . A groove  160  extending through braces  65 ,  66  and  67  receives the stringers  152  and  154 . The stingers  152  and  154  slide along the grooves  160  with lip  162  removing any debris thereon. 
     With primary emphasis now directed to  FIG. 9 , the preferred electrical control circuit has been designated by the reference numeral  200 . Nominally 120 volt A.C. voltage is supplied to the circuitry with a standard three-prong plug  201 . Voltage is transmitted across input lines  203 ,  204  through fuses  205 A and  205 B. Switch  32  may be user selected to apply power directly to tilt-over safety switch  170 . Alternatively, switch  32  may direct voltage via photoelectric switch system  34  to switch  170  or it may be switched “off”. System  34  automatically energizes and controls the apparatus depending upon ambient light conditions. Safety tilt-over switch  170  disables the apparatus when the tower is tipped over approximately thirty degrees from vertical. 
     Voltage applied to node  206  is applied to a thermostat-controlled switch  126 . Switch  126  applies voltage to node  207  to energize both motor  100  and resistive heating element  122 A. Voltage on node  206  also energizes the primary  208  of high-voltage transformer  102 . As long as there is voltage across nodes  206 ,  206 B the pilot light  42  will be energized as well. High voltage outputted from the transformer across lines  151  and  153  electrifies the electrocution grid  60  previously discussed. 
     For best results the device should be operated during the night. It should be placed away from humans. During daylight hours it is preferably placed in the shade. During operation system  20  attracts mosquitoes  22  by projecting air  138  outwardly from tower  50 . Air  138  comprises a mixture of moisture  88 , aromatics  98  and heated and pressurized air  128 . The projected air  138  creates several thermal and pressure gradients around housing  25  that simulate human breathing and body heat. The aromatics  98  and moisture  88  further enhance the simulation of a live animal such as a human or fowl. 
     The system  20  first draws air  108  into base  30  through several slits  83  as a result of the operation of a fan  100 . Of course switch  32  must be activated. As air  108  enters the casing interior  86 , it mixes with aromatics  98  escaping from drawer  90  and moisture  88  from wick  85 . The mixed air is then blown upwardly into heating tower  50 . 
     As the blown air  118  enters the tower section  120 , it passes an electric heater  122 . Heater  122  warms air  118  to a preselected temperature as determined by thermostat  126 . The heated air  118  is also slightly pressurized by baffle  115  as it moves into dispersal chamber  130 . 
     Air  128  moving into chamber  130  is projected outwardly through several orifices  132 . As air leaves chamber  130 , it begins cooling and depressurizing as it moves outwardly. Cooled and depressurized air  138  establishes multiple thermal and pressure gradients once outside tower  50 . Even more thermal and pressure gradients are created once air  138  leaves housing  25 . 
     The multiple gradients attract mosquitoes  22 . As attracted mosquitoes  22  enter housing  25  through guard  70 , they alight upon grid  60  where they are subsequently disintegrated (i.e. Mosquito  23 ). Since system  20  attracts mosquitoes without ultraviolet light, beneficial insects and other insects are not attracted to system  20 . In other words, since system  20  uses the infrared spectrum to attract target insects such as mosquitoes, the system  20  does not attract large numbers of non-target insects. 
     Experience dictates that the air  138  passing guard  70  should approximate 100 degrees Fahrenheit. In other words, on windy or cold days, the thermostat  126  should run heater  122  longer than warm, hot days. 
       FIG. 10  shows a second preferred embodiment of the invention. According to this embodiment, apparatus  200  provides a heated air space  202  between outer wall  202   a  and inner wall  202   b  of the main body of the apparatus  200 . Space  202  may reheated by any appropriate mechanism such as a heating tube, resistive conductors, or equivalent heat producing mechanisms, such as heater  122  as shown in  FIGS. 7 and 8 . The heated space  202  creates a heat blanket or gradient around the periphery of the apparatus, which attracts mosquitoes to the outer surface  202   a . A fan  204  driven by a motor  206  causes the air flow in the direction of arrows  220 , from the vicinity of outer surface  202   a  and down into interior chamber  221  of the apparatus  200  thorough an opening between a canopy  210  and the top of the main body of the apparatus  200 . 
     An electrocution grid  212  is provided in the interior chamber  221 . Mosquitoes are attracted to the surface  202   a  by the surrounding heat and are sucked into the apparatus by air currents  220 , where they are forced down onto the grid  212  and electrocuted. Mosquito remains then fall into a removable trap  214 , which is removed from the bottom of the apparatus  200  for disposal. A wire mesh  216  covers the bottom of the apparatus to prevent access to the interior. 
     The embodiment of  FIG. 10  provides a measure of safety by placing the electrocution grid inside the body of the apparatus, precluding inadvertent contact by humans. The electrocution grid is mounted horizontally so that mosquito remains fall into trap  24  through the force of gravity, eliminating the need to periodically clean the electrocution grid. 
       FIG. 11  shows a motion pole  300  for use with a mosquito killing apparatus according to the embodiments of the invention, and in particular with the embodiment of  FIG. 10 . Motion pole  300  includes a vertical arm  302  for placement in the ground or mounting on a floor, and a horizontal arm  306 . Arm  306  contains a track in which an auger screw  308  is installed.

     In operation, the apparatus  200  slowly transverses the path between the limit switches  312  on the horizontal arm  306 , simulating motion of a living animal, which provides an attractant to mosquitoes in the surrounding area. 
     A final embodiment of the invention is shown in  FIGS. 12-17 . 
     First provided is a base  404 . The base has an upper surface. The base has an upwardly facing trough  406 . The trough is in an annular configuration. 
     A recovery lower chamber  408  is provided. The recovery lower chamber has an upper end. The recovery lower chamber has a lower end. The lower end is received and supported by the trough. The recovery lower chamber has a vertically extending cylindrically configured central extent  410 . The lower end of the recovery lower chamber has lower slots  412 . The lower slots extend from a lower location within the trough to an upper location above the trough. In this manner when water is within the trough and air flows through the lower slots from interior of the recovery lower chamber such air flow will become moisture laden. The upper end of the recovery lower chamber is in a frusto-conical configuration with upper slots  414 . The upper end of the recovery lower chamber terminates at an elevated location in a circular support plate  416 . The central extent of the recovery lower chamber has an interior surface with an open-cell lining  418 . The open-cell lining is adapted to absorb and dispense moisture in response to the moisture laden air passing there across. 
     An upper chamber  422  is provided. The upper chamber has an upper end and a lower end. The upper chamber has a vertically extending cylindrically configured central extent  424 . The lower end of the upper chamber has an apertured lower circular reception plate  426 . The lower circular reception plate is positioned on and coupled to the circular support plate. The upper end of the upper chamber is in a frusto-conical configuration. The upper chamber has an annular opening  428 . The annular opening is between the upper end of the upper chamber and the central extent of the upper chamber. 
     Provided next is a fan  432 . The fan is provided in the upper chamber. In this manner the air flow is directed in a recirculating path of travel downwardly through the upper chamber and the recovery lower chamber then outwardly through the lower slots in the lower end of the recovery lower chamber then upwardly to and through the annular opening in the upper chamber then downwardly again through the fan and the upper chamber. 
     A carbon dioxide tank  436  is provided. The carbon dioxide tank is provided in the recovery lower chamber. In this manner a quantity of carbon dioxide is dispensed into the recirculating path of travel of the air flow. The carbon dioxide tank is chosen from the class of carbon dioxide tanks. The class of carbon dioxide tanks includes small tanks and large tanks and refillable tanks and non-refillable tanks. 
     A gaseous flow assembly is provided. The gaseous flow assembly includes a solenoid  440 . The gaseous flow assembly includes an input line  442 . The gaseous flow assembly also includes an output line  444 . The input line couples the tank and the solenoid. The output line has an exterior extent on the upper chamber with apertures and a foam covering constituting a lower reservoir  446 . The output line has an intermediate extent. The intermediate extent is provided in the annular opening. The intermediate extent has an aperture and a foam covering constituting an upper reservoir  448 . 
     An ultrasound box  452  is provided next. The ultrasound box is provided in the upper chamber. In this manner a heartbeat of a human is simulated. Further in this manner insects to be killed are attracted. 
     A cylindrical heater  456  is provided. The cylindrical heater is provided in the upper chamber. In this manner the recirculating air and the carbon dioxide are heated. 
     Further provided are electrically charged screens  460 . The electrically charged screens are provided in the lower end of the upper chamber. The electrically charged screens are adapted to electrocute and kill insects. 
     Provided last is a power source  464 . A control assembly  466  is provided. The power source and control assembly power and control the fan and the carbon dioxide tank and the ultrasound box and the heater and the screens. The controlling includes a cycle of carbon dioxide release of about 2 minutes followed by operation of the fan for about 1 minute. The cycle is repeated for about 5 hours. The operation of the heater and the operation of the ultra sound box are continuous during the cycle of the fan and the canister. 
     In the prior art, the CO2 is released at the four orifices for two minutes while the fan is off mixing with the heated air, then the fan comes on for one minute and this is repeated for 5 hours. When the fan comes on to vacuum in the midges and mosquitoes into the unit, it also blows away the heated gaseous attractions away from the unit which quickly dissipates. The release of the heated gaseous attractants without any control or direction, attracts midges and mosquitoes to the area of the unit and then the midges and mosquitoes follow the gaseous and heated air flow away from the unit. The addition of the recovery chamber and control of the lost attractants by 66.5 percent causes the midges and mosquitoes to stay at the unit and be captured. The CO2 being released for 2 minutes will now fall into the new recovery chamber with open cell liner that will be recirculated. The midges and mosquitoes are attracted to the recovery chamber and when the fan starts recirculating the attractants, the midges and mosquitoes will follow the attractants and be trapped or electrocuted. 
     The new water reservoir of the present invention actually puts moisture into recirculated attractants. The air flow now passes over the water and enhances the other attractants producing a larger rate of kill. In the prior art there was no way to add moisture to the attractants. 
     The new reservoir will also be used to mix the attractants, such as lemon and other fragrances that will mix with the other attractants in the in the recirculated air flow to which the midges and mosquitoes are attracted. 
     The gaseous reservoirs of the present invention for the main and the body are open cell material, like a sponge. The gaseous attractant is released into the open cell gaseous reservoirs and absorbed, allowing the attractant to be slowly and continuously released out. In the prior art the attractant was released out into the air with no control and lost. 
     The ultrasound device of the present invention pumps liquid through a tube recirculating to mimic the sound of a heart beat is incorporated with the gaseous air flow that mimics breathing as well as the heat that mimics body temperature.
