FIG. 1 is a diagram of an embodiment of a system that includes a plurality ofbio-medical units 10 embedded within a body and/or placed on the surface of the body to facilitate diagnosis, treatment, and/or data collections. Each of thebio-medical units 10 is a passive device (e.g., it does not include a power source (e.g., a battery)) and, as such, includes a power harvesting module. Thebio-medical units 10 may also include one or more of memory, a processing module, and functional modules. Alternatively, or in addition to, each of thebio-medical units 10 may include a power source. - In operation, a transmitter emits 12
electromagnetic signals 16 that pass through the body and are received by areceiver 14. Thetransmitter 12 andreceiver 14 may be part of a piece of medical diagnostic equipment (e.g., magnetic resonance imaging (MRI), X-ray, etc.) or independent components for stimulating and communicating with the network of bio-medical units in and/or on a body. One or more of thebio-medical units 10 receives the transmittedelectromagnetic signals 16 and generates a supply voltage therefrom. Examples of this will be described in greater detail with reference toFIGS. 8-12 . - Embedded within the electromagnetic signals 16 (e.g., radio frequency (RF) signals, millimeter wave (MMW) signals, MRI signals, etc.) or via separate signals, the
transmitter 12 communicates with one or more of thebio-medical units 10. For example, theelectromagnetic signals 16 may have a frequency in the range of a few MHz to 900 MHz and the communication with thebio-medical units 10 is modulated on theelectromagnetic signals 16 at a much higher frequency (e.g., 5 GHz to 300 GHz). As another example, the communication with thebio-medical units 10 may occur during gaps (e.g., per protocol of medical equipment or injected for communication) of transmitting the electromagnetic signals 16. As another example, the communication with thebio-medical units 10 occurs in a different frequency band and/or using a different transmission medium (e.g., use RF or MMW signals when the magnetic field of the electromagnetic signals are dominate, use ultrasound signals when theelectromagnetic signals 16 are RF and/or MMW signals, etc.). - One or more of the
bio-medical units 10 receives the communication signals 18 and processes them accordingly. The communication signals 18 may be instructions to collect data, to transmit collected data, to move the unit's position in the body, to perform a function, to administer a treatment, etc. If the receivedcommunication signals 18 require a response, thebio-medical unit 10 prepares an appropriate response and transmits it to thereceiver 14 using a similar communication convention used by thetransmitter 12. -
FIG. 2 is a diagram of another embodiment of a system that includes a plurality ofbio-medical units 10 embedded within a body and/or placed on the surface of the body to facilitate diagnosis, treatment, and/or data collections. Each of thebio-medical units 10 is a passive device and, as such, includes a power harvesting module. Thebio-medical units 10 may also include one or more of memory, a processing module, and functional modules. In this embodiment, the person is placed in an MRI machine (fixed or portable) that generates amagnetic field 26 through which theMRI transmitter 20 transmits MRI signals 28 to theMRI receiver 22. - One or more of the
bio-medical units 10 powers itself by harvesting energy from themagnetic field 26 or changes thereof as produced by gradient coils, from the magnetic fields of the MRI signals 28, from the electrical fields of the MRI signals 28, and/or from the electromagnetic aspects of the MRI signals 28. Aunit 10 converts the harvested energy into a supply voltage that supplies other components of the unit (e.g., a communication module, a processing module, memory, a functional module, etc.). - A
communication device 24 communicates data and/orcontrol communications 30 with one or more of thebio-medical units 10 over one or more wireless links. Thecommunication device 24 may be a separate device from the MRI machine or integrated into the MRI machine. For example, thecommunication device 24, whether integrated or separate, may be a cellular telephone, a computer with a wireless interface (e.g., a WLAN station and/or access point, Bluetooth, a proprietary protocol, etc.), etc. A wireless link may be one or more frequencies in the ISM band, in the 60 GHz frequency band, the ultrasound frequency band, and/or other frequency bands that supports one or more communication protocols (e.g., data modulation schemes, beamforming, RF or MMW modulation, encoding, error correction, etc.). - The composition of the
bio-medical units 10 includes non-ferromagnetic materials (e.g., paramagnetic or diamagnetic) and/or metal alloys that are minimally affected by an externalmagnetic field 26. In this regard, the units harvest power from the MRI signals 28 and communicate using RF and/or MMW electromagnetic signals with negligible chance of encountering the projectile or missile effect of implants that include ferromagnetic materials. -

other data 30 from one or more of thebio-medical units 10 via thecommunication device 24, theWAN communication device 34, and thenetwork 42. In this manner, a person(s) operating the remote monitors 36 may view images and/or thedata 30 gathered by thebio-medical units 10. This enables a specialist to be consulted without requiring the patient to travel to the specialist's office. - In another example of operation, one or more of the
computers 38 may communicate with thebio-medical units 10 via thecommunication device 24, theWAN communication device 34, and thenetwork 42.

bio-medical units 10 may read and/or write data from or to one or more of thedatabases 40.

Note that if theprocessing module 50 includes more than one processing device, the processing devices may be centrally located (e.g., directly coupled together via a wired and/or wireless bus structure) or may be distributedly located (e.g., cloud computing via indirect coupling via a local area network and/or a wide area network). Further note that when theprocessing module 50 implements one or more of its functions via a state machine, analog circuitry, digital circuitry, and/or logic circuitry, the memory and/or memory element storing the corresponding operational instructions may be embedded within, or external to, the circuitry comprising the state machine, analog circuitry, digital circuitry, and/or logic circuitry. Still further note that, the memory element stores, and the processing module executes, hard coded and/or operational instructions corresponding to at least some of the steps and/or functions illustrated inFIGS. 1-41 . - The
power harvesting module 46 may generate one or more supply voltages 56 (Vdd) from one or more of MRIelectromagnetic signals 16,magnetic fields 26, RF signals, MMW signals, and body motion.

In another embodiment, the transmitter section includes an oscillator that produces an oscillation. The outbound symbol stream provides phase information (e.g., +/−Δθ [phase shift] and/or θ(t) [phase modulation]) that adjusts the phase of the oscillation to produce a phase adjusted RF or MMW signal, which is transmitted as theoutbound RF signal 60. In another embodiment, the outbound symbol stream includes amplitude information (e.g., A(t) [amplitude modulation]), which is used to adjust the amplitude of the phase adjusted RF or MMW signal to produce the outbound RF orMMW signal 60. - In yet another embodiment, the transmitter section includes an oscillator that produces an oscillation.

MMW signal 60 to produce an amplified inbound RF or MMW signal. The receiver section may then mix in-phase (I) and quadrature (Q) components of the amplified inbound RF or MMW signal with in-phase and quadrature components of a local oscillation to produce a mixed I signal and a mixed Q signal. The mixed I and Q signals are combined to produce an inbound symbol stream. In this embodiment, the inbound symbol may include phase information (e.g., +/−Δθ [phase shift] and/or θ(t) [phase modulation]) and/or frequency information (e.g., +/−Δf [frequency shift] and/or f(t) [frequency modulation]).

step 512, the method branches back to step 510 when theprocessing module 50 determines that it is not time to perform receive communication. Atstep 512, the method continues to step 514 when theprocessing module 50 determines that it is time to perform receive communication. - At
step 514, theprocessing module 50 directs theEM transceiver 174 to receive the inbound modulated EM signals. Theprocessing module 50 may decode messages from the inbound modulated EM signals 146 such that the messages include one or more of a echo signal collection assist request, a status request, a records request, a sensor data request, a processed data request, a position request, a command, and/or a request for MRI echo signal data. Note that the message may be decoded from the inbound modulated EM signals 146 in one or more ways including detection of the ordering of the magnetic gradient pulses, counting the number of gradient pulses, the slice pulse orderings, detecting small differences in the timing of the pulses, and/or demodulation of the MRI RF pulse. - At
step 516 theprocessing module 50 determines if there is at least one message pending to transmit (e.g., in a transmit queue). Atstep 518, the method branches back to step 502 when theprocessing module 50 determines that there is not at least one message pending to transmit. Atstep 518, the method continues to step 520 when theprocessing module 50 determines that there is at least one message pending to transmit. - At
step 520, theprocessing module 50 determines when it is time to perform transmit communication in accordance with the MRI sequence. In an embodiment, theEM transceiver 174 may transmit outbound modulated EM signals 180 between any of the MRI sequence steps. In another embodiment, theEM transceiver 174 may transmit the outbound modulated EM signals 180 between specific predetermined steps of the MRI sequence. In another embodiment, theEM transceiver 174 may transmit the outbound modulated EM signals 180 in parallel with specific predetermined steps of the MRI sequence, but may utilize a different set of frequencies unique to theEM transceiver 174. - At
step 522, the method branches back to step 520 when theprocessing module 50 determines that it is not time to perform transmit communication. Atstep 522, the method continues to step 524 when theprocessing module 50 determines that it is time to perform transmit communication. - At
step 524, theprocessing module 50 directs theEM transceiver 174 to prepare the outbound modulated EM signals 180 based on the at least one message pending to transmit. Theprocessing module 50 may encode messages into the outbound modulated EM signals 180 such that the messages include one or more of a status request response, a records request response, a sensor data request response, a processed data request response, a position request response, a command response, and/or a request for MRI echo signal data response. The method branches back tostep 502. -
FIG. 41 is a flowchart illustrating the coordination of bio-medical unit task execution where theprocessing module 50 determines and executes tasks with at least one otherbio-medical unit 10. The method begins atstep 592 where theprocessing module 50 determines if communication is allowed. The determination may be based on one or more of a timer, a command, available power, a priority indicator, an MRI sequence, and/or interference indicator. - At
step 594, the method branches back to step 592 when theprocessing module 50 determines that communication is not allowed. Atstep 594, the method continues to step 596 when theprocessing module 50 determines that communication is allowed. Atstep 596, theprocessing module 50 directs thecommunication module 48 to communicate with a plurality ofbio-medical units 10 utilizing RF and/or MMW inbound and/or outbound signals. Theprocessing module 50 may decode messages from the RF and/or MMW inbound and/or outbound signals inbound signals. Atstep 598, theprocessing module 50 determines if communications with the plurality ofbio-medical units 10 is successful based in part on the decoded messages. - At
step 600, the method branches back to step 592 when the processing module determines that communications with the plurality ofbio-medical units 10 is not successful. Note that forming a network with the otherbio-medical units 10 may be required to enable joint actions. Atstep 600, the method continues to step 602 when theprocessing module 50 determines that communications with the plurality ofbio-medical units 10 is successful. - At
step 602, theprocessing module 50 determines the task and task requirements. The task determination may be based on one or more of a command from aparent bio-medical unit 10, external communications, a preprogrammed list, and/or in response to sensor data. The task requirements determination may be based on one or more of the task, a command from aparent bio-medical unit 10, external communications, a preprogrammed list, and/or in response to sensor data. Note that the task may include actions including one or more of drilling, moving, sawing, jumping, spreading, sensing, lighting, pinging, testing, and/or administering medication. - At
step 604, theprocessing module 50 determines the control mode based on one or more of a command from aparent bio-medical unit 10, external communications, a preprogrammed list, and/or in response to sensor data. Note that the control mode may include autonomous, parent (bio-medical unit), server, and/or peer. - At
step 606, theprocessing module 50 determines if task execution criteria are met based on sensor data, communication with otherbio-medical units 10, a command, a status indicator, a safety indicator, a stop indicator, and/or location information. Note that the task execution criteria may include one or more of safety checks, position information of thebio-medical unit 10, position information of otherbio-medical units 10, and/or sensor data thresholds. - At
step 608, the method branches back to step 606 when theprocessing module 50 determines that the task execution criteria are not met. Atstep 608, the method continues to step 610 when theprocessing module 50 determines that the task execution criteria are met. Atstep 610, theprocessing module 50 executes a task element. A task element may include a portion or step of the overall task. For example, move one centimeter of a task to move three centimeters. - At
step 612, theprocessing module 50 determines if task exit criteria are met based on a task element checklist status, sensor data, communication with otherbio-medical units 10, a command, a status indicator, a safety indicator, a stop indicator, and/or location information. Note that the task exit criteria define successful completion of the task. - At
step 614, the method branches back to step 592 when theprocessing module 50 determines that the task exit criteria are met. In other words, the plurality ofbio-medical units 10 is done with the current task and is ready for the next task. Atstep 614, the method continues to step 616 when theprocessing module 50 determines that the task exit criteria are not met. - At
step 616, theprocessing module 50 directs thecommunication module 48 to communicate with the plurality ofbio-medical units 10 utilizing RF and/or MMW inbound and/or outbound. Theprocessing module 50 may decode messages from the RF and/or MMW inbound and/or outbound signals inbound signals. Note that the messages may include information in regards to task modifications (e.g., course corrections). Atstep 618, theprocessing module 50 determines if communications with the plurality ofbio-medical units 10 is successful based in part on the decoded messages. - At
step 620, the method branches back to step 592 when the processing module determines that communications with the plurality of bio-medical units is not successful (e.g., to potentially restart). Note that maintaining the network with the other bio-medical unit may be required to enable joint actions. Atstep 620, the method continues to step 622 when the processing module determines that communications with the plurality of bio-medical units is successful. - At
step 622, theprocessing module 50 determines task modifications. The task modifications may be based on one or more of a command from aparent bio-medical unit 10, and/or external communications. The task modifications determination may be based on one or more of the task, a command from aparent bio-medical unit 10, external communications, a preprogrammed list, and/or in response to sensor data. The method branches back to step 606 to attempt to complete the current task. - As may be used herein, the terms “substantially” and “approximately” provides an industry-accepted tolerance for its corresponding term and/or relativity between items. Such an industry-accepted tolerance ranges from less than one percent to fifty percent and corresponds to, but is not limited to, component values, integrated circuit process variations, temperature variations, rise and fall times, and/or thermal noise. Such relativity between items ranges from a difference of a few percent to magnitude differences. As may also be used herein, the term(s) “coupled to” and/or “coupling” and/or includes direct coupling between items and/or indirect coupling between items via an intervening item (e.g., an item includes, but is not limited to, a component, an element, a circuit, and/or a module) where, for indirect coupling, the intervening item does not modify the information of a signal but may adjust its current level, voltage level, and/or power level. As may further be used herein, inferred coupling (i.e., where one element is coupled to another element by inference) includes direct and indirect coupling between two items in the same manner as “coupled to”. As may even further be used herein, the term “operable to” indicates that an item includes one or more of power connections, input(s), output(s), etc., to perform one or more its corresponding functions and may further include inferred coupling to one or more other items. As may still further be used herein, the term “associated with”, includes direct and/or indirect coupling of separate items and/or one item being embedded within another item. As may be used herein, the term “compares favorably”, indicates that a comparison between two or more items, signals, etc., provides a desired relationship. For example, when the desired relationship is that
signal 1 has a greater magnitude thansignal 2, a favorable comparison may be achieved when the magnitude ofsignal 1 is greater than that ofsignal 2 or when the magnitude ofsignal 2 is less than that ofsignal 1. - The present invention has also been described above with the aid of method steps illustrating the performance of specified functions and relationships thereof. The boundaries and sequence of these functional building blocks and method steps have been arbitrarily defined herein for convenience of description. Alternate boundaries and sequences can be defined so long as the specified functions and relationships are appropriately performed. Any such alternate boundaries or sequences are thus within the scope and spirit of the claimed invention.
