the present invention discloses a microscopic , mobile , and controllable version of an array element mesh system ( aems ), adapted for use in precision - oriented , organic or inorganic applications , typically for exploration and diverse intervention tasks , such as microsurgeries , micromanipulation , and transport and delivery of materials . in one preferred advanced embodiment , the device has microscopic proportions ( e . g ., sub - 1000 nm ) so that it may be used in precision - oriented applications ( e . g ., medical - and / or other small - scale - applications . one with ordinary skill in the art , however , will recognize that the proportions of the device need not be restricted in this manner . the small - form - factor version of the aems , is based on the original aems concept , but further incorporates one or more of locomotion means and / or “ course - awareness ” of its path in transit ; and / or “ course direction ” to control the direction of its path in transit ; locomotion means and / or impeller means ; navigation or direction finding and reporting means ; tools and / or peripheral actuators ; internal and / or external control system means for remote monitoring and control of the device ; and possibly a hitch means for linking other devices or auxiliaries . in alternative embodiments , the device is built as an electronic device or as an electromechanical device ; as an organic or inorganic device , as a passive or as an active device ; and / or as feasible , based on specific user requirements . the propulsion and locomotion means of the aems - based device permit versions to ambulate on predetermined paths or dynamically - determined paths . in one possible preferred embodiment , the means for propulsion can comprise either traction feet or rollers , which would permit the device to squeeze between cells as applicable or needed for various medical repair , replacement , or amelioration applications . there are various methods used to be certain about the location of the aems . one of the methods uses the concept of “ dead reckoning ” as implemented in the aems ( e . g ., “ move x steps on the x - axis ; y steps on the y - axis , z steps on the z - axis ”). this allows it to precisely track its movements and / or be precisely tracked . in this way , the device can track its steps . the location where the device enters the target ( a body or other target object ) is referred to as the origin location or zero location ( place of embarkation ). when the aems keeps track of its location , and / or reports its location to an external control system , it becomes easy to control by a doctor or technician . this is not to be confused with the concept of the aems device “ zero state ”, wherein the aems is implemented (“ flat ” ( essentially 2d ). an “ initialization state ” can be any initial state ( or configuration ) of a device ( not just flat ). regarding location and navigation within a body , the doctor can watch and / or listen ( using monitors and stethoscopes ) to watch the deployed device &# 39 ; s progress as it transits a body or other target object . also simultaneously the device can “ count steps ” while it proceeds toward any destination inside a target object . between what the doctor sees and controls , and the device itself “ counting steps ” and feeding back data ( if provisioned to do so ), we can calculate where the device is within the target body or object , in x , y , and z planes , on an instantaneous basis . separately , navigation and direction finding using triangulation apparatus is illustrated : the device is inserted ( e . g .) into a human to do knee microsurgery . at the kneecap , or the aems insertion point ( the aems zero location ), a plurality of static monitoring devices ( 3 - 4 ) can be deployed on the zero location skin surface . these radiodomes are placed around 360 ° of an approximate circle or ellipse perimeter . using 4 radiolocation devices , with one transceiver at each 90 °. the transceivers are skin - surface - deployed monitors that listen for device beacons ( radiolocation signals ) transmitted by the inserted aems device ( s ). “ skin surface monitor transceivers ” triangulate to get a fix on the moving device within the target body or object . the doctor or technician can observe a video display ( e . g .) connected to the external control system ( if provisioned ). the device carefully tracks all steps in terms of x , y , and z axis steps . . . it knows where it is located , if provisioned to do that . also , “ navigation ” per se is a relative term . even if the device knows exactly where it is and the doctor or tech knows where it is . . . the device still might not be exactly on the work area target objective it is sent to fix . . . e . g ., repair a knee tendon . or the device may be moved into the wrong part of a target work area . the tool actuators , depending on explicit implementation and configuration capabilities , permit alds to perform predetermined or dynamically determined actions . for example , the actuator tools may allow the ald to perform different programmed tasks , such as penetration of the body of the subject by piercing and / or cutting , destruction of unwanted cells , or the deployment of replacement cells . let &# 39 ; s say that in our knee operation , the admin system , and the bug , and the doctor all agree that the bug is in the right place to insert some undifferentiated embryonic stem cells into the area of scarring or broken tendons in the subject &# 39 ; s knee . the one or more aems bug ( s ) in there first extend the embedded injector ( s ) and flow out the stem cells into the area . let &# 39 ; s say there are some obstructions in the area of the site where the new stem cells are to be inserted . the bug will determine it has to clear an area of obstructions ( get out the micro scalpel ) and machete - away the interfering or dead tissue . some versions of the bug might have minilasers that can evaporate the target obstruction . other versions of the bug might have an excavator tool that dredges out some obstruction and processes it for evaporation or exportation . the administrative and control system means allow alds ( auto locomotive devices ) and lds ( locomotive devices ) to be optionally controlled either by external control signals and / or by preprogrammed autonomous control signals from an internal microprocessor or microcontroller . for example , an external control person , typically a doctor or medical technician ( or in some applications , an “ expert system ”), can preprogram device movements and actions and monitor ongoing movements and actions , permitting instantaneous course corrections and enroute activities as needed . [ nb : use of the term “ ald ”, the term “ ld ”, and the phrase “ ald ” and / or “ ld ” are summarized by the shorthand term “ ald ”. when “ ald ” is written , it equally means “ ald ”, “ ld ”, and “ ald ” and / or “ ld ”, for brevity sake .] alternatively , the ald may transform its physical configuration in response to internal control signals . for example the ald may transform its &# 39 ; shape from that of an insect - like “ bug ” into the shape of a serpentine - like “ snake ” of very small diameter in comparison to its length . . . e . g ., the ald could make a snake of the cylindrical dimensions of 20 microns by 200 microns ( a 1 : 10 ratio of width to length ). in one embodiment of the invention , the administrative and control means may additionally comprise one or more imaging means to detect the position of alds on or inside the target subject . in various embodiments of the invention , the imaging means may be computed tomography ( ct ), magnetic resonance imaging ( mri ), or positron emission tomography ( pet ). in one preferred embodiment , the imaging means comprises the 3d body holographic scanner technology recently developed at pacific northwest national laboratory ( pnnl ), which is capable of detailed high - speed 3d imaging . the administrative and control system may alternatively be analogous to a type of 3 - d radar , or use existing tactics from in nuclear medicine and the like , such as effectuating the dyeing and / or radioactive tagging of structures inside the body so their progress can be monitored externally . the administrative and control system can also be interconnected into a medical expert system , a developed or increasingly being developed artificial intelligence medical expert system . finally , the hitch means allows an ald to connect to another ald . in one embodiment , the hitch may be comprised of micromechanical means physically linking one ald to another . in an alternative embodiment , the hitch means may polarize the ald , such that the “ negative ” pole of one ald electromagnetically connects to the “ positive ” pole of another ald . there may be no physical hitching means required or even necessary . maybe i should be claiming an ald device of specifiable dimensions . . . maybe multiple deployment of multiple bugs would for some applications be better than an ald train . . . which might not make sense from the optimization standpoint , even if it would be superficially apparent to be the most efficient and effective . maybe if multiple bugs could be dispatched either at the same time , or separately , they could be capable of rejoining into a train but would not necessarily do so . ideally much of the intelligence needed to drive and monitor the bug would be in the admin control system . . . it would be easier in some options and asks less head scratching to contemplate feasibility of an ald train . using the hitch means , two or more alds may be connected to accomplish one or more target objective ( s ) undertaken upon or within target work areas ( hereinafter referred to as an “ ald train .”). the details of ald train composition are configured on a case - by - case basis , depending on the work the ald train is expected to do . ald trains will generally be mass - designed and mass - assembled , with further customization depending on target requirements . ald trains can be assembled during their manufacture or intelligently fabricated dynamically . ald trains can also be chemically assembled , e . g ., in a liquid colloidal dispersion . the ald train can dynamically change its physical dimensions or characteristics , by connecting or disconnecting alds , to suit changing mission needs while underway toward a work area or work objective . external controllers or system administrators or operators , such as a doctor or a technician , may exercise control over the ald train as a whole , or may elect to control each ald in the ald train separately ( i . e ., detach one or more alds in the ald train , to be deposited by or jettisoned from the train ). these examples notwithstanding , alds do not need to be linked in a linear fashion , but could be linked in such a way as to create a 2 - d or 3 - d structure . the ald can be configured and implemented in a variety of user - specified embodiments , such that it performs one or more specialized functions . one typical ald is the “ locomotive / navigation ald ” ( ln - ald ), which is a self - controlled preprogrammed ald , typically used to propel itself and one or more ald trains along a specified or calculated path to reach a target work area or target objective area . an alternate specialized ald is the “ payload ald ” ( p - ald ), which further includes a means for containing and / or supporting extrinsic matter , such that the ald can transport the extrinsic matter within the target . the means may include a platform , tank , bin , etc . to transport the matter . alternative structures are anticipated , depending on the nature of the extrinsic matter . the p - ald can be used , for example , to transport organic matter such as particular molecules , amino acid chains , dna sequences , etc . the p - ald may also be used to transport micromechanical equipment , including — but not limited to — cameras , stents , or other devices . an alternative embodiment of the ald further includes a “ control tail ,” ( essentially , a guide wire ) which is a structural and / or umbilical means for coupling to a larger instrument ( such as a surgical tool ). the control tail is connected to the administrative 26 and control system means as well as the hitch means of the ald , so that the ald or ald train may be controlled in response to signals from an external source , such as a doctor . one or more of a scanning tunneling microscope ( stm ) and / or an atomic force microscope ( afm ) can be used to actuate the control tail . the present invention has many possible applications . for example , the invention can be used to import new , healthy mitochondria into cellular arrays . mitrochondria can be either “ healthy ” or “ unhealthy ”, which directly corresponds with the state of health of the subject &# 39 ; s body . the present invention may also be used to import and / or replace and repair damage to intercellular structures , such as damage caused to neural pathways in the brain by head trauma . neural damage vastly affects an individual ; as one example , if neural structures in the cerebellum are damaged , the individual &# 39 ; s balance , movement , and coordination are affected . for example , to restore or improve “ balance ”, repairs that may be needed may be establishing or improving “ balance ” by allowing proprioceptor signals from the inner ear to be transmitted from the inner ear to the balance center in the brain . from the perspective of the balance center in the brain , “ balance ” in the human body is largely a combined function of gravity , direction , speed , momentum , mass , and other factors . similarly , the combination of balance , movement , and coordination may be improved if , e . g ., the proprioceptor signals and the neural pathways in the brain that they feed can be reconnected and / or amplified . in the case where proprioceptor signals are not getting through to the balance center in the brain , e . g ., it may be necessary to repair damaged areas and / or replace signal carrying capabilities in structures which run from the proprioceptors in the inner ear to the balance center in the brain . when signals are not getting through normal pathways , it is necessary that existing proprioceptor signal relays are bypassed with new signal relays . in the case of a job to repair a myocardial infarction , the specific ald trains can be configured with p - alds , which can be implemented in target locations , such as the site of a myocardial infarction ( scar which forms after some heart attacks ). in the process of the perambulation of the ald to ameliorate the myocardial infarction , the system of the myocardial infarction amelioration includes ( 1 ) external monitoring and control instruments operated by a doctor and ( 2 ) ald trains adapted for myocardial infarction remediation . to establish a remediation operation , first the area of the infarction is precisely mapped . based on the size of the area to be repaired , the number of ald trains needed for the repair is calculated . a number of ald trains of predetermined sizes and complements are estimated . the trains are configured to include p - alds , which carry : organic scaffold materials and deposition tools for depositing the scaffold on the target remediation site , beating myocytes , and drugs and / or cellular nutrients . in one embodiment of the invention , the ald is implemented as an electromechanical device . the administrative and control means may comprise a microprocessor , which can process and execute control signals , and an electronic transceiver , allowing the ald to receive control signals from other alds or external sources . the means for self - propulsion is coupled to the microprocessor , such that it can respond to control signals received from the processor . the means for self - propulsion can receive commands from the microprocessor chip relating to the velocity — both speed and direction — of the means for propulsion ; this allows the microprocessor chip to steer the ald . the ald also includes a power source , which is connected to the microprocessor and permits the ald to operate . in various preferred embodiments of the invention , the ald may receive power through the transceiver in the form of external electromagnetic excitation , may possess a fully self - contained power source , or may consume body fluids of the individual host . the present invention further discloses methods and systems for controlling and administering the ald . the administrative system allows doctors , medical assistants , or other individuals to control the velocity of the ald , as well as tool deployment and tool activation . the administrative system comprises an administrative computer , a means for communication , and one or more alds . the administrative computer is a standard computer terminal , allowing individuals means to input commands and view data . the administrative computer is attached to the means for communication , which allows the administrative computer to communicate with the alds . in the case of electromechanical alds , the means for communication in the administrative ald may be an electromechanical ald . there are multiple different ways to communicate with organic devices , some involving transmission of intelligence ; others simply using “ brute force ” methods of communication . in this manner , a doctor may use the administrative computer to control the alds . an aems adapted for facilitating inner ear surgery is commanded to replace ear cilia into the inner ear . we have the lead ln - ald and one or more p - alds introduced by the doctor into the subject &# 39 ; s ear canal . that point of insertion is the “ aems zero location ”. the doctor or tech monitors ( and tweaks if needed ) the path of progress from the ear canal entry point , the zero location into the inner ear . the device crawls along the ear canal to its target destination within a target object . alternatively , the doctor injects the devices beneath the inside skin of the inner ear canal . to illustrate a practical example , the problem is that the target object person &# 39 ; s inner ear cilia are malfunctioning — either atrophied or non - responsive due to chronic exposure to loud low - frequency noise ( like years in the engine room of a large ship ). the invention hauls in a “ p - ald ” load of new cilia and / or inner ear goop . the invention could also haul in embryonic stem cells . but in this case the importation of cilia into an inner ear could be re - usage of cilia from the subjects ear which has extra cilia in it due to no damage . . . in this case the bug would not only be used to install new cilia into the inner ear . . . but would also be used to extract a graft of functioning cilia from the subject &# 39 ; s own undamaged ear . . . or ear area less damaged . we have not yet determined whether undifferentiated embryonic stem cells can “ make cilia ” ( or other specialized structures ). the limits of embryonic stem cells are currently the subject of the inventor and many other researchers as well . possible downstream applications could include one or more of bone marrow transplant and renovation applications ; reproductive medicine applications ; knee ( joint ) application ; floater retrieval from aqueous humor of the eye or other eye surgery applications ; and many others . actuators in general can also be adapted for other extraction / relocation requirements . given the human body &# 39 ; s predilection for rejecting things that it does not recognize , e . g ., while it is likely that one &# 39 ; s brother or sister can provide a person with bone marrow . . . it is not likely that bone marrow can be extracted from another who is not closely related to the subject without it being rejected in an unrelated subject &# 39 ; s body . another concept : a “ minitest feature ”. it can test the miscibility of the ( e . g ., imported stem cells or bone marrow ) with the body . . . i . e ., test that the target work area tissue is compatible with the potential - to - be - installed tissue ( which is carried by the bug .) another concept : the analogy of “ epoxy a and epoxy b ” . . . i . e ., there are 2 or more devices , each carries a reactant or tissue or some part of the “ recipe ” needed for the target objective . chemical reactions can be effected by combining multiple tissues and reactants or chemicals , at the target work area , with the sequential timing as needed to effectuate the objective , or accomplish the mission . fig2 , magnified area 6 to show teeth that provide directional friction fig4 , aems beginning transport by magnetic oscillation down outer ear canal fig5 , aems proceeding by magnetic oscillation further down outer ear canal 2 gently sloping surface that produces little force f 1 4 steeply sloping surface that produces a stronger force f 2 6 area of stepped surface that is detailed in fig2 center portion of aems unit with biocompatible coating or shell there are many other implementations possible , which may be different from examples discussed herein , but which are not discussed herein . accordingly , one skilled in the art will probably see that other combinations and synergies and teaming agreements are likely , without deviating from the spirit of this application for a united states patent .
