Electronic systems, devices and methods are provided to accurately measure both food intake and physical activity in a subject. A device is provided to be placed on a subject which records video as well as other physiological and/or environmental data. Video data can be analyzed along with other data obtained by the device to determine food consumption and physical activity of the subject, much of which is accomplished by automated computer-implemented processes.

摘要:
Electrodes providing excellent recording and physical stability. The present invention encompasses electrodes that include a plurality of small teeth that possess a novel design shape and orientation. The shallow and relatively long teeth preferably run parallel to the rim of the electrode that presses against the patient's skin. When the electrode is twisted onto skin, the tiny teeth penetrate the stratum corneum and move nearly horizontally under the stratum corneum, thus anchoring the electrode securely to the skin. The electrodes of the present invention cause minimal discomfort to the patient since the small teeth do not extend to the pain fibers which are located in deeper layers of the skin. The electrodes may house a wide diversity of electronic components to enable numerous experimental and medical implementations. The electrodes the present invention may also be used wirelessly either singularly or as an array so that no electrode leads extend away from the patients body. The electrodes of the present invention may be fabricated using precision photo-chemical etching techniques that are well known in the art. The present invention also includes an electrode installation device that preferably employs the electrodes of the present invention.

Apparatus and method of communicating data employing current pulses transmitted by an implanted device through living biological tissue to an external device. The method also contemplates transmission of current pulses from the external device through living biological tissue to an implanted device. Uniquely configured antenna electrodes are preferably employed in the implanted device. Increase in signal-to-noise ratio is achieved through synchronization. The method may be employed in diagnostic, therapeutic and general monitoring activities in connection with human beings.

摘要:
An apparatus for powering an implant includes first energy interface elements, a removeably attachable holding device and a first energy source, such as a battery. An energy conversion circuit converts first energy into second energy which is transmitted within the body of the patient to the implant. Also, an apparatus for providing information to an implant that includes first energy interface elements and a housing that includes a processor operatively coupled to the first energy interface elements and an energy source operatively coupled to the processor. The processor is structured to generate an information signal and cause the signal to be transmitted within the body of the patient for delivery to the implant. Associated methods are also provided.

摘要:
Implants include a single tapped coil antenna having a first section and a second section for wireless power transfer, data downlink and data uplink. A modulated wireless power transfer signal is received by the tapped coil antenna and used to provide electrical power. The modulation is detected to generate downlink data. A switch is used to charge a section of the tapped coil antenna by establish a current which is then be interrupted by opening the switch. The switching produces a high-amplitude pulsed magnetic field (PMF) for use in data uplink over a large distance between the implant and an external transceiver.

A wireless energy transfer system includes a first energy transfer unit having at least one resonant frequency, a second energy transfer unit having the at least one resonant frequency, and a load. The first wireless energy transfer unit includes a first coil magnetically coupled to a first wireless energy transfer cell, and the second wireless energy transfer unit includes a second coil magnetically coupled to a second wireless energy transfer cell. The first coil receives first energy and through the magnetic coupling between the first coil and the first wireless energy transfer cell, the first wireless energy transfer cell is caused to generate second energy, wherein the second wireless energy transfer cell receives the second energy and through the magnetic coupling between the second wireless energy transfer cell and the second coil, the second coil is caused to provide third electromagnetic wave energy to the load.
