The apparatus and method maximize the gain in the wireless link using simultaneous conjugate matching, to increase power transfer within the transmitted power signal, wherein the simultaneous conjugate matching accounts for interaction between the transmit antenna and the receive antenna, including the complex impedance of the medium between the transmit antenna and the receive antenna.
 
Description
BACKGROUND
Implantable medical devices (IMDs) are a rapidly growing area of technology. In-vivo monitoring and treatment of key biological parameters can greatly assist in managing health and preventing disease. IMDs are complete systems often incorporating signal transducers, wireless data transceivers and signal processing circuits. Power consumption in these devices requires batteries, which must be replaced periodically, or inductive power coupling antennae, both of which dominate device volume, increasing patient discomfort and severely restricting the range of viable applications.
Previous inductive powering links for IMDs operate in the low MHz requiring loop antenna diameters of a few cm and near-perfect transmitter and receiver alignment to deliver sufficient power. This choice of frequency is usually explained by saying that tissue losses become too large at higher frequencies and referring to a qualitative analysis. For these low MHz inductively coupled links the range is much less than a wavelength and thus the links satisfy the near field approximation to Maxwell's equations. Therefore resonant tuning techniques can be used to achieve the maximum energy transfer from the source to the load circuits for these links. Inductive coupling antennae of this size are viable for retinal implants where there is an existing cavity in the eye-socket but are much too large for many other IMDs such as implantable glucose sensors.
 
The physics behind wireless powering is described first. A time-varying current is set up on the transmit antenna. This gives rise to a time-varying magnetic field. The time-varying magnetic field, in turn, gives rise to an electric field. The electric field induces a current on the receive antenna. Then, this induced current on the receive antenna intercepts the incident electric field and/or magnetic field from the transmit antenna, and generates power at the receiver. Prior devices for wireless transmission of power to medical implants mainly operate based on inductive coupling over the near field in conjunction with a few based on electromagnetic radiation over the far field.
 
Devices based on inductive coupling operate at very low frequency, 10 kHz to 1 MHz. A wavelength is long relative to the size of the transmit and receive antennas. They are usually a few cm in diameter. Most energy stored in the field generated by the transmit antenna is reactive, that is, the energy will go back to the transmitter if there is no receiver to intercept the field. The separation between transmit and receive antennas is very small, usually a few mm. The low frequency and the short separation mean that there is apparently no phase change between the field at the transmitter and the incident field at the receiver. The increase in the transmit power due to the presence of the receiver mostly delivers to the receiver, like a transformer. Prior devices are therefore designed using the transformer model where various tuning techniques are proposed.
 
To deliver sufficient power to the implant using inductive coupling based devices, the receive antenna attached to the implant is of a few cm in diameter which is too large. It is required to be in close proximity to the transmit antenna on the external device. The power link is very sensitive to misalignment between the antennas. For example, some devices use a magnet to manually align them.
 
Devices based on electromagnetic radiation operate at much higher frequency, 0.5 GHz to 5 GHz. Transmit and receive antennas are on the order of a wavelength. For example, a wavelength is 12.5 cm at 2.4 GHz. Therefore, transmit and receive antennas are usually at least a few cm in diameter which is of similar size to those devices based on inductive coupling. As the transmit antenna is comparable to a wavelength, radiated power dominates. The receive antenna is in the far field of the transmit antenna and captures a very small fraction of the radiated power. That is, most of the transmit power is not delivered to the receiver. The link efficiency is very low. In return, the distance between the transmit antenna and the tissue interface is farther, a few cm to 10's of cm, the depth of the implant inside the body is larger, 1 cm to 2 cm, and the link is insensitive to misalignment between antennas. Prior devices are designed using independent transmit and receive matching networks.
 
The above two prior approaches have a common disadvantage: they require large receive antennas, 1 cm to a few cm. The paper by Poon et al. titled “Optimal Frequency for Wireless Power transmission over Dispersive Tissue” showed that small receive antenna is feasible. The authors show that the optimal transmission frequency for power delivery over lossy tissue is in the GHz-range for small transmit and small receive antennas (a few mm in diameter.) The optimal frequency for larger transmit antenna (a few cm in diameter) and small receive antenna is in the sub-GHz range. That is, the optimal frequencies are in between 0.5 GHz and 5 GHz. Compared with the frequency used in prior devices based on inductive coupling, the optimal frequency is about 2 orders of magnitude higher. For a fixed receive area, the efficiency can be improved by 30 dB which corresponds to a 10 times increase in the implant depth, from a few mm to a few cm. For a fixed efficiency, the receive area can be reduced by 100 times, from a few cm to a few mm in diameter. When the transmit antenna is close to the tissue interface, the separation between the transmit and the receive antenna approximately equals the implant depth. Inside the body, the wavelength is reduced. For example, a wavelength inside muscle is 1.7 cm at 2.4 GHz. Consequently, the transmit-receive separation is on the order of a wavelength. The device operates neither in the near field nor in the far field. It operates in the mid field. Furthermore, the transmit dimension of a few cm will be comparable to a wavelength.
 
SUMMARY
The inventions described herein present apparatus and methods to deliver power wirelessly from an external device using an antenna or an antenna array to an implant.
 
Multiple antennas can be used in the external device to maximize the power transfer efficiency. The use of multiple transmit antennas also reduces the sensitivity of the power link to the displacement and orientation of the receive antenna.
 
These inventions as described can provide one or more of the following advantages: smaller antenna size; greater transfer distance inside body; and reduced sensitivity to misalignment between transmit and receive antennas, as the link gain is increased through choice of frequency, matching, and beam forming which requires the ability to locate the receiver.
These inventions also provide a novel method to achieve feedback of information from the internal device to the external device about the location of the internal device and properties of the medium in between. Conventional techniques require explicit feedback of information from the internal device to the external device. The present invention achieves implicit feedback by exploiting the fact that the internal device is close to the external device, and therefore the external device should be able to sense the presence of the internal device and properties of the medium in between.
 
In one aspect there is provided apparatus and methods for applying simultaneous conjugate matching to wireless links.
In another aspect is provided adaptive tuning of that simultaneous conjugate matching.
 
In a particular embodiment, the apparatus and methods operate with wireless power signals in the sub-GHz or the GHz-range, more specifically, in between 0.5 GHz and 5 GHz.
 
In a particular aspect, there is provided apparatus and methods for increasing a gain of a transmitted power signal in a wireless link when operating in a mid field wavelength that is within a range between wavelength/100 to 100*wavelength and within a medium having a complex impedance between a transmit antenna and a receive antenna. The apparatus and methods maximize the gain in the wireless link using simultaneous conjugate matching, to increase power transfer within the transmitted power signal, wherein the simultaneous conjugate matching accounts for interaction between the transmit antenna and the receive antenna, including the complex impedance of the medium between the transmit antenna and the receive antenna.
 
In another aspect is provided apparatus for wireless power transmission within an environment of unknown transmission characteristics comprising: a wireless power transmitter, the wireless power transmitter including: an adaptive match transmit circuit with a tunable impedance, which supplies a tunable impedance to a power signal having a frequency of at least 0.5 GHZ; and a wireless transmitter; and a wireless power receiver, the wireless power receiver including: a receive antenna configured to receive the transmitted power signal as a received power signal; an adaptive match receive circuit, wherein the adaptive match receive circuit receives the received power signal, and is configured to match the tunable impedance, in dependence upon the environment of unknown transmission characteristics, to thereby increase a gain of the received power signal.
 
In a particular aspect the adaptive match receive circuit provides a feedback signal to the adaptive match transmit circuit, wherein the feedback signal provides an indication of a gain of the power signal as received at the wireless power transmitter for a particular tuned impedance.

In vivo means "in the place" (not in a lab)

This patent shows how an implant can be stimulated from a distance by the use of an antenna. Every cell phone is an antenna. Some antennas are relays so someone at a  remote distance can operate your implants.  Several antennas beingn beamed to the same GPS location can create a field so anywhere you go within that field, your implants will still be stimulated.

TELEMETRY

AM/FM multi-channel implantable/ingestible biomedical monitoring telemetry system
US 5415181 A
Abstract
A multi-channel circuit for telemetering signals representing physiological values from a point in a human body to a receiver (24) outside of the body. The two signals (S1, S2) other than the temperature signal (27') are used to provide two frequency modulated signals (14, 16) summed by an amplifier (18) with the summed FM signal then being applied to amplitude modulate (21) a carrier (8) whose frequency varies as a function of temperature. The resulting FM/AM signal (22) is telemetered inductively outside of the body to an external receiver (24). Appropriate demodulation, filter, and shaping circuits within the external circuit detect the FM signals (14, 16) and thus produce three independent frequencies two of which are the original physiological variables and the third a function of local temperature. Real time plot of the two physiological variables can be obtained using FM discriminators while the temperature dependent frequency is best monitored by a counter. http://www.google.com/patents/US5415181

SIGNAL PROCESSING

Dynamic synapse for signal processing in neural networks
US 6363369 B1
Abstract
An information processing system having signal processors that are interconnected by processing junctions that simulate and extend biological neural networks. Each processing junction receives signals from one signal processor and generates a new signal to another signal processor. The response of each processing junction is determined by internal junction processes and is continuously changed with temporal variation in the received signal. Different processing junctions connected to receive a common signal from a signal processor respond differently to produce different signals to downstream signal processors. This transforms a temporal pattern of a signal train of spikes into a spatio-temporal pattern of junction events and provides an exponential computational power to signal processors. Each signal processing junction can receive a feedback signal from a downstream signal processor so that an internal junction process can be adjusted to learn certain characteristics embedded in received signals.  http://www.google.com/patents/US6363369

STALKING TECHNOLOGY

If you are a Targeted Individual, you may be familiar with stalking.  People come in your house without it seems even opening the door. Sometimes it is as if there  were someone in your house but you can't see them. Other times, people may "pop up" between the switch of your eyes from left to right. There are technologies we don't know about, but considering science is far beyond what is actually disclosed to the public, teleportation and cloaking may be possible.  There are patents filed for both these systems.

"HAVE YOU EVER BEEN DIAGNOSED WITH SCHIZOPHRENIA?"
 
Why would someone ask you that because you are taking their picture while they stalk you?  The first thing stalkers do is pretend they are doing nothing.  Then they loudly declare they are doing nothing. Then they say you are crazy. Then they threaten to call the police. The first thing police do is ask you if you have ever been diagnosed with schizophrenia or other mental illness.  This is a trap.  How do you answer that?  Even if a person did have a mental handicap, that would be a reason to be more kind and loving to them.  If a person had a physical handicap, you might help them by opening the door or helping them across the street.
 
The trap is making you look like you are endangering the public or yourself.  Under ordinary instances, people would just look the other way and go on with their business.  But when the authorities are taking advantage of every opportunity to hospitalize you so you can be implanted with RFID and GPS chips.
 
Labeling a person crazy by a stalker is intended to put you on the defensive.  Do you really have to defend your mental health to a stranger who is following you and directing energy toward you to hurt you?  This is a classic stance of people who need a reason to ease their conscience so they can torture or kill the "natives." It is when people find a way to relegate others to the realm of less than human, that they  can then torture and kill them without conscience.
 
This document should explain some of this It comes from the website about the Community Oriented Policing which includes stalking activities by individuals and companies.
