CROSS-REFERENCE TO RELATED APPLICATION 
   This application claims the benefit of and priority to U.S. Provisional Patent Application No. 60/805,702, filed Jun. 23, 2006, entitled STABILIZING HOLDER FOR SENSORY DEVICE, which document is hereby incorporated by reference to the extent permitted by law. 

   BACKGROUND OF THE INVENTION 
   The present invention relates generally to holding devices, and more particularly to an improved holding device used for holding a sensory device, such as microphones, for use on musical instruments such as drums. 
   Acoustical drums have long been an integral part in musical groups and performances. 
   Various types of sensory devices have been affixed to acoustical drums to measure, enhance, record, and/or monitor different aspects (e.g., sound, images, temperature, humidity, light-level, etc.) associated with an acoustical drum or the environment corresponding to the acoustical drum. 
   For example, in some cases, it is desirable to electrically amplify a drum&#39;s sound to obtain an increased level of volume and/or sound characteristics. This often involves placing a microphone in close proximity to the drum. The signal produced by the microphone is usually sent to an external speaker by means of a cord. More recently, in some cases, a radio transmitter located in or attached to the microphone transmits a signal which is sent to a receiver which in turn is connected to the amplification system. In either case, the microphone needs to be supported by a mechanical means to obtain proper placement of the microphone to the drum. 
   Previously, the use of a microphone stand comprised of a weighted base or other means of support, a vertical shaft and in some cases, an additional horizontal boom assembly atop the vertical shaft, and a clip to hold the microphone in place. 
   These stands have several disadvantages. For example, the stands can transfer vibrations from the floor or stage set. These stands also can transfer vibrations through the support and vertical shaft of the microphone stand. All of these vibrations can be transferred onto the microphone itself. These vibrations can cause the microphone to produce an unwanted signal. The vibrations can also cause unwanted activation of sound capturing devices attached to the microphone. 
   Another disadvantage is that limited space may also present a problem for placement of the numerous microphone stands needed to amplify various drums at once, as in the case of a drum set. Bass drums of these drum sets are routinely amplified by means of a support base, vertical shaft and horizontal boom assembly which houses the microphone on one end and a counter-weight on the other end. The microphone is then adjusted to face the bass drum or placed partially inside the drum, through an opening created in the front drumhead. The weight of the typically large microphones frequently used for amplifying bass drums require the counter-weight to extend beyond the vertical plane of the front of the bass drum. This placement creates a trip hazard for other musicians. This placement also increases the likelihood of accidentally displacing the microphone due to the outwardly extending boom and counter-weight assembly. The additional space required to place the microphone stand on the floor in front of the bass drum, also requires additional floor space in front of the bass drum which may not be available, as in the case of the drums being set up on an elevated platform. 
   Another disadvantage is that the time and effort spent in assembling the above devices, outfitting them with the microphones, achieving the proper placement and alignment of the microphone, and connecting them to the amplification system is often considerable. 
   There have been various efforts made to affix the drum microphones directly inside the drum in the past. One previous effort is disclosed in the “Electroacoustically amplified drum and mounting bracket”, by Randall May, in U.S. Pat. Nos. 4,168,646, 4,570,522, 6,121,528. The aforementioned effort consists of a microphone mounting bracket which is installed on the inside of the drum, using the pre-existing drum hardware mounting fasteners as means of attachment. This effort has several disadvantages. For example, the mounting bracket has the likelihood of transferring vibrations of the drum shell induced by the percussion of the musician&#39;s striking instrument against the striking surface of the drumhead, creating a possibly unwanted signal being sent by the microphone to the amplification system. Other disadvantages are that the aforementioned effort is also a semi-permanent installation, thereby making removal and replacement of the system somewhat of an inconvenience. 
   Another embodiment of the aforementioned patents to May requires the need to create a hole in the shell of the drum involved in the installation, to accept installation of an electrical connection device. This device is used to connect the internal microphone to the amplification system. At least one disadvantage of this embodiment is that the installation of the connection device may be undesirable to some owners and players of the instrument. Another aspect of the Randall May invention that has disadvantages is the distance adjustment available between the interior surface of the drum shell and the microphone mount. Being a rigid mounting bracket, the amount of adjustment range from the inside of the drum shell to the microphone itself is restricted and minimal at best. 
   Another effort at microphone placement on drums is disclosed in U.S. Pat. No. 5,574,236, entitled “Drum muffling and microphone suspension assembly”, to Webber, Steven R. This effort is a device consisting of a drum baffle system with the option of installing a microphone mount, in which the said microphone mounting apparatus is suspended on a plurality of coil springs which are attached to the drum muffling assembly. This effort has several disadvantages. For example, the coil springs may create unwanted audio effects due to the individual coils of the springs striking one another. Another disadvantage is that the effort disclosed by Webber also requires the use of the drum baffle element to utilize the microphone holder, which eliminates the choice of the individual to use only the microphone mount by itself. 
   Another effort at microphone placement on drums is disclosed in U.S. Pat. Nos. 5,703,306 and 6,424,723, to Jing. Jing discloses a clamp or holder which is attached directly to the drum&#39;s tuning rim which supports the microphone in the desired position. This effort has several disadvantages. For example, this method may increase the risk of damage to the microphone by the impact of the drummer&#39;s striking instrument. This effort also requires additional time and effort to prepare the system for use. 
   BRIEF SUMMARY OF THE INVENTION 
   The present invention provides a means for support and positioning of a sensory device for use in a drum-type musical instrument. The invention utilizes a rigid central main mounting unit and a plurality of elastomer cords providing support of said main mounting unit. The main mounting unit accepts any variety of sensory devices (e.g., sound, images, temperature, humidity, light-level, etc.). For example, the main mounting unit accepts industry standard microphones, microphone clips and other devices. The elastomer cords attach the main mounting unit to one or more interior support hooks. Alternatively or in combination with the interior support hooks, the elastomer cords can also engage the pre-existing tuning lugs which are present in plurality around the outside circumference of the drum shell of most drum instruments. The elastomer cords can engage the main mounting unit by utilizing any of a series of holes located around the outside of the main mounting unit. The support provided by the elastomer support cords is sufficient to retain the main mounting unit in place, keeping the device totally isolated from the stage or floor, the drum shell and immediate surroundings. 
   One embodiment of the present invention provides an advantageous device for installing and utilizing a sensory device, microphone or other device in conjunction with a drum or series of drums.

   DETAILED DESCRIPTION OF THE INVENTION 
     FIG. 1  illustrates the present invention in one of its embodiments. The rigid central main mounting unit  1  may be constructed of any material with substantial strength to withstand the outward pressures exerted by the elastomer support cords  35 . For example, the main mounting unit  1  may comprise aluminum, metal, steel, plastics, composite materials such as carbon fiber, strong woods and laminates of woods, or a combination thereof. A plurality of holes  5  are created around the outside edge  1 A of the main mounting unit  1  to accept the attachment hooks or loops located on the ends of the support cords. The main mounting unit  1 , with the sensory device  40  attached, is housed inside the drum shell  50 . The main mounting unit  1  is supported inside the drum shell  50  by means of the elastomer cords  35 . One end of the elastomer cords  35  engages the main mounting unit  1  by utilizing a hook  30  which is passed through the user&#39;s choice of holes  5  present in plurality around the circumference of the main mounting unit  1 . The other end of the elastomer cord  35  and hook  30  engages into any of the loops  85  which are installed on the inside of the drum shell  50 B. These loops  85  are held in place on the inside of the drum shell  50 B by the drum&#39;s existing tuning hardware  70  screws or bolts. The sensory device&#39;s  40  signal transmission cable  45  passes through a port  65  which is present in the drumhead  60 . The drumhead  60  is held in place on the drum shell  50  by means of friction between the tuning hoop  55  and the drum shell  50 . The tuning hoop  55  is provided inward pressure by the hoop retainers  75  and tuning lugs  80 , which are engaged by means of threads into the tuning hardware  70 . The elastomer support cords  35  comprise materials comprising elastic and non-elastic properties and/or combinations thereof. For example, the elastomer support cords  35  comprise solid rubber products, a series of rubber strands, a series of rubber strands encased within a woven nylon outer covering, or a combination thereof. 
   A hook  30  is located at each end of the elastomer support cords  35 . The hook  30  comprises a rigid material. For example, the hook  30  comprises aluminum, metal, steel, plastics, composite materials such as carbon fiber, strong woods and laminates of woods, or a combination thereof. Optionally, a loop, not shown, constructed of the same piece of elastomer cord is formed on the ends and secured in position. The loop may be secured in position by a metal squeeze clamp, heat or chemical adhesion, a nylon friction-engaged tie-strap, or a combination thereof. In either case, the hook  30 , loop or combination of the two, located on the ends of the elastomer support cords  35  must be of sufficient size to engage the receiving holes  5  located on the main mounting unit  1 , as well as engage in the hooks or loops  85  which are installed around the inside of the drum shell  50  by utilizing the fasteners and pre-existing tuning hardware located around the inside circumference of the drum, or to engage the drum&#39;s tuning lug hardware  85 , located around the outside circumference of the said drum shell  50 . 
     FIG. 2  illustrates an embodiment comprising the main mounting unit  1 A and sensory device  40  with a signal transmission cable  45  connected. Located on the main mounting unit  1  is a mounting plate  1 B of either the same piece of material, bent under pressure to 90 degrees or a separate piece of material attached to the main mounting unit  1  in the same position as the aforementioned horizontal extension is shown on the drawings. This mounting plate  1 B contains a slot  1 C utilized to affix the attachment hardware which is matched to the device to be supported, on either the top or the bottom of the mounting plate  11 B. The slot  1 C allows for movement of the threaded post  10  or other device receiver in a perpendicular direction to the main mounting unit  1 . Most microphones, microphone clips, thread sizes and some other devices are standardized within the industry, however, the main mounting unit  1  may be affixed with any hardware the user chooses, as long as sufficient room exists for mounting the device without interfering with the operation of the mounting system. In most cases, the preferred attachment device would be a threaded post  10  having threads on one end and an area of extending material on the other, which is sized to fit the slot  1 C in the horizontal extension mentioned in the previous section with sufficient clearance to move freely along the slot  1 C. The end opposite the outside threads of the threaded post  10  is drilled a hole  100 B in the center of the post  10 , to accept a means of attachment by a bolt or screw which is sized to fit the threads in the end of the post. The threaded post  10  comprises a durable material. For example, the threaded post  10  comprises steel, composites, or a combination thereof. The sensory device  40  is mated with its appropriate mounting hardware  10 , which is attached to the mounting tab  1 B by utilizing friction provided by the thumbscrew  20 . The slot  1 C in the mounting tab  1 B provides perpendicular adjustment positioning of the sensory device  40  to the main mounting unit itself  1 A. A collar  25  located on the sensory device  40 &#39;s appropriate mounting hardware  10  disallows for rotational movement of the sensory device  40  on its mounting hardware  10 . Engagement of the collar  25  against the bottom of the sensory device  40  is achieved by means of turning the collar  25  in a counter-clockwise direction until acceptable friction is applied. A plurality of holes  5  are located around the circumference of the main mounting unit  1 A which are utilized during further installation processes. In one embodiment, the plurality of holes  5  can be grommets, rings, or eyelets exhibiting vibration-absorbing, vibration-damping, or noise suppressing capability. Preferably, the grommets, rings, or eyelets  5  are made of neoprene, rubber or other like vibrational damping material. 
     FIG. 3  illustrates an exploded view of an embodiment of the present invention and is shown with an industry-standard sensory device  40  for illustrative purposes.  1 A is the main mounting unit. The mounting tab  1 B may be either a continuation of the main mounting unit  1 A bent under pressure to 90 degrees during manufacture, or a separate piece attached at 90 degrees to the main mounting unit  1 A. In either case, the mounting tab  1 B offers a slot  1 C which allows for perpendicular positioning adjustment of the sensory device  40 . A locking collar  25  is provided as means of a jam nut, which screws onto the threaded post  10  before the supported device  40  is attached to the threaded post  10 . The locking collar  25  is tightened against the supported device  40  to hold the device in place once it has been threaded onto the post. The installer will obtain the desired placement of the sensory device  40  or microphone&#39;s direction and tighten the locking collar  25  against the bottom side of the supported device  40  by means of turning the collar  25  backward until it engages the device  40 , with friction then holding the direction of the microphone  40  securely in place. This piece  25  too, should be constructed of a durable material such as steel or composites. A bolt, thumbscrew or screw  20 B is the means of fastener which passes through the slot  1 C and engages the threads on the threaded post  10 , thus attaching both components to the main mounting assembly  1 . The bolt  20 B may be solid metal, or a combination of steel and composites which would form a thumbscrew type knob  20  on the end opposite the threads, for ease of use as is shown in the drawings. A flat or lock washer  15  is located between the fastener and horizontal extension. Friction produced by tightening the bolt; or thumbscrew  20 B into the threaded post  10  will retain the threaded post  10  in position along the distance of the slot  1 C. The sensory device  40  will be mounted on the mounting tab  1 B by being matched to its appropriate mounting hardware  10 . A collar  25  located on the sensory device  40 &#39;s appropriate mounting hardware  10  disallows for rotational movement of the sensory device  40  on its mounting hardware  10 . Engagement of the collar  25  against the bottom of the sensory device  40  is achieved by means of turning the collar  25  in a counter-clockwise direction until acceptable friction is applied. The mounting hardware  10  engages the slot  1 C and is held in place by means of a thumbscrew  20  whose threaded post  20 B is engaged into a threaded hole  10 B provided in the bottom of the mounting hardware  10 . A washer  15  is located between the thumbscrew  20  and the mounting tab  1 B. Located around the circumference of the main mounting unit  1 A are a plurality of holes  5  which will allow for engagement of the hooks  35  with the main mounting unit  1 A. The hooks  30  are located on both ends of the elastomer cords  35 , in which one hook  35  is engaged into any of the holes  5  located on the main mounting unit  1 A. The hook  30  on the other end of the elastomer cord  35  is utilized during further installation of the main mounting unit  1 A. 
     FIG. 4  illustrates one embodiment of the present invention comprising the main mounting unit  1  inside a standard drum shell  50  with the drumhead  60  opposite the striking surface of said drum being shown in cut-away.
