Abstract: Cardiac Output (CO) has traditionally been difficult, dangerous, and expensive to obtain. Surrogate measures such as pulse rate and blood pressure have therefore been used to permit an estimate of CO. MEMS technology, evolutionary computation, and time-frequency signal analysis techniques provide a technology to non-invasively estimate CO, based on precordial (chest wall) motions. The technology detects a ventricular contraction time point, and stroke volume, from chest wall motion measurements. As CO is the product of heart rate and stroke volume, these algorithms permit continuous, beat to beat CO assessment. Nontraditional Wavelet analysis can be used to extract features from chest acceleration. A learning tool is preferable to define the packets which best correlate to contraction time and stroke volume.

Abstract: A vibrational therapy assembly treating and preventing Deep Venous Thrombosis, and other conditions, using vibrational energy.

Abstract: Processes and apparatus for indicating a shower stage are disclosed. The apparatus includes a housing having an inlet and an outlet with a shower water passage extending between them. The inlet communicates with a water supply and the outlet communicates with shower head apertures. A light indicator system in the housing is automatically operable in a first condition during a first stage of the session and a second condition during a second stage, the lighting conditions being visible to the person who is showering. The stages may be determined by the passage of time or by the passage of shower water volume through the device. Seeing the first and second conditions prompts the person who is showering to use less shower water.

Abstract: Systems and methods are disclosed for providing therapeutic treatment using vibrational stimulation, ultrasound stimulation and electro-stimulation. The combined therapeutic treatment allows for more flexible and effective treatment of bone-loss related and other ailments and conditions by providing one or a combination of vibrational, ultrasound and/or electro-stimulation to a patient.

Abstract: A therapeutic device, such as an exercise device, includes the principles of osteogenic repair by incorporating a loading mechanism into the exercise device. By doing so, the therapeutic device provides an increased osteogenic effect, thereby enhancing the benefits of the therapy. As an example, a exercise device includes a support surface for supporting all or part of the bodily tissue of an individual using the device. A linear or rotary loading mechanism associated with the frame or a rotational element of the exercise device drives the support surface at a selected load and frequency, thereby inducing mechanical loading of bodily tissue adjacent to the support surface sufficiently to facilitate the growth, development, strengthening, and/or healing of bone tissue. The loading mechanism may be incorporated into any exercise device, including standard exercise devices such as rowing machines, stair climbing machines, elliptical trainers, bicycles, cross-country ski trainers, treadmills, or weight trainers.

Abstract: Methods for enhancing blood and lymph flow in the extremities of a human subject are disclosed. In one aspect, the methods rely on a stimulus effective to displace the skin of a plantar or palmer surface of the subject, thereby enhancing blood and lymph flow in the extremity associated with the stimulated plantar or palmer surface. In another aspect, the methods rely on an electrical stimulus to directly stimulate cutaneous receptors in a plantar or palmer surface of the subject, thereby enhancing blood and lymph flow in the extremity associated with the stimulated cutaneous receptors. Apparatus for enhancing blood and lymph flow in the extremities of a human subject according to the methods of the present invention are also disclosed.
