Wireless medical monitoring device
US 8979756 B2
Abstract
Described herein is a patient monitoring system that includes a body network (16) with at least one sensor (12) that senses physiological information about a patient and a cognitive device (2) for communicating the physiological information to a remote location. The cognitive device includes a cognitive radio (4), a cognitive monitor (10), and a transmitter (8). The cognitive radio (4) checks detected frequency spectra (6) for unused bandwidth and recommends one or more bands on which to transmit clinically relevant information received from the body network (16) to the remote location; the cognitive monitor (10) receives the information from the body network (16), prioritizes the information based at least in part on a set of rules (30), and selects which information to transmit based on the prioritization and the recommended transmission bands; and the transmitter (8) transmits the selected information as a junction of priority over at least one or the recommended transmission bands.

Wireless power transmission for implantable medical devices
US 8634928 B1
Abstract
Described is an apparatus and method 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 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.

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.

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.

Patent application: Method and system to record, store and transmit waveform signals to regulate body organ function
Note: The final approved patent no longer includes the images listed in this patent application rather there it is an external sensor.
Abstract
A method to record, store and transmit waveform signals to regulate body organ function generally comprising capturing waveform signals that are generated in a subject's body and are operative in the regulation of body organ function and transmitting at least a first waveform signal to the body that is recognizable by at least one body organ as a modulation signal.
