Abstract: 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.

Abstract: Electrodes providing excellent recording and physical stability. Electrodes that include a plurality of small teeth that possess a novel design shape and orientation are disclosed. 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 teeth penetrate nearly horizontally under the stratum corneum. The electrodes cause minimal discomfort to the patient since the teeth do not extend to the pain fibers which are located in deeper layers of the skin. The electrodes may house a diversity of electronic components to enable numerous experimental and medical implementations. The electrodes may also be used wirelessly without electrode leads. The electrodes may be fabricated using precision photo-chemical etching techniques that are well known in the art. An electrode installation device that preferably employs the electrodes is also disclosed.

Abstract: 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.

Abstract: An implantable device. The implantable device includes a computing device, a microelectromechanical system (MEMS) pH sensor connected to the computing device, and a communication system connected to the computing device.

Abstract: 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.

Abstract: 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.

Abstract: The present invention is a method directed to selectively send non-textual information through a network that best adapts to the capacity of the receiving device, such as a display monitor on a remote computer. The method is comprised of steps of uploading the size of the remote display window and calculating the size of each image on the remote monitor. Wavelet coefficients of 1D, 2D or 3D images are produced and selectively transmitted to the monitor, with the most informative information transmitted first. The remote computer renders an image on the monitor based on the received coefficients. When the user increases the image size, additional coefficients are transmitted, and the resolution of the image is improved. The transmission stops when the display resolution of the remote monitor is met.
