Abstract: A system using combined electrocardiography (EKG) and photoplethysmography (PPG) sensing, to determine venous oxygen saturation is described. The system uses averaging of similar pulses based on Prior (or n?1) R-to-R pulse wave duration, and current (or n) R-to-R pulse wave duration for evaluation of the metabolic reserve and/or stress of the patient.

Abstract: A system using combined electrocardiography (EKG) and photoplethysmography (PPG) sensing to assess intra-arterial fluid volume is described. The system uses averaging of similar pulses based on prior (n?1; n minus 1) R-to-R pulse wave duration, and prior-prior (n?2; n minus 2) R-to-R pulse wave duration, to determine a patient's fluid status and whether it is below or above optimal intravascular hydration.

Abstract: Systems and methods for improving or preventing a condition, such as the treatment of pain syndromes and migraine headaches are disclosed. A method for treating pain can include one or more of the steps including identifying a region of the patient comprising glabrous tissue; positioning the region of the patient comprising glabrous tissue into an enclosed chamber; adjusting the relative humidity of the enclosed chamber sufficient to create a physiologic effect. The method need not involve altering the temperature within the enclosed chamber.

Abstract: A system for synchronizing a target device to a cardiac cycle, including: (a) a target device that collects data or performs an operation that is to be timed to the cardiac cycle; (b) a signaling device that emits a signal indicating the occurrence of a cardiac contraction and/or ECG feature; and (c) a calibration device that determines the relationship of the signal from the signaling device to the actual cardiac cycle. In operation, the calibration device calculates a time offset between the timing of the cardiac contraction as determined by the signaling device and the timing of the cardiac contraction and/or ECG feature as determined by the calibration device, and then provides the time offset to the target device.

Abstract: A scanning system having a plurality of X-ray sources together with a single X-ray detector that uses sequentially emitted overlapping fan-shaped or cone-shaped beams to image a target such as the leg of a horse. The X-ray detector is rotated closer to the target and the X-ray emitter sources are rotated at a greater distance from the target. The positioning systems of the X-ray detector and the X-ray sources may be operated independently of one another, with each of the X-ray detector and the X-ray sources being also rotated about separate axes passing therethrough (while they are both being rotated around the target) as a way to keep the X-ray sources and the X-ray detector parallel to one another while working in very tight spaces.

Abstract: Systems for large animal fluoroscopy having independently positionable X-ray emitter and X-ray detector arms on either side of the animal providing independent movement of the X-ray emitter and X-ray detector in multiple degrees of freedom.

Abstract: The present invention relates to the production of lower extremity supportive products, including boot, shoes, sandals, leg braces, etc. One embodiment of the present invention relates to a method for providing a three-dimensionally customized lower extremity product. The method includes measuring and recording data related to a three-dimensional representation of a customer's lower extremities in an activity-specific optimal stance. The three-dimensional representation includes specific anatomical position information including extensions, flexions, rotations, inversions, eversions, etc. The three-dimensional representation also includes surface information including foot shape, ankle shape, sole shape, etc. The measurement and recordation is performed at a convenient location such as in close proximity to the customer's residence or at an airport terminal. The customized lower extremity product is then manufactured at an independent location.

Abstract: The present invention relates to lightweight ski systems. One embodiment of the present invention relates to a lightweight ski stability system for improving performance while maintaining lightweight characteristics. The ski stability system includes a ski and one or more weighted members. One weighted member is positioned on the upper surface of the ski within 10 centimeters of the tip contact point. A second optional weighted member is positioned on the upper surface of the ski within 10 centimeters of the tail contact point. The contact points refer to a lengthwise position before the tip or tail laterally curve upward. The weighted members weigh at least 3% of the ski weight. The disposition of these weighted members at one or both of the contact points increases the rotational inertia characteristics of the lightweight ski while minimizing the resulting weight. A second embodiment of the present invention relates to a method of increasing the rotational inertia of a lightweight ski.

Abstract: A high-speed fluorescence scanner for scanning a sample at equal angles is disclosed. The scanner has most of its optical components, including a light beam source, a detector, and various filters, lenses, and reflectors, in a fixed position, removed from the scan head. The lightweight scan head contains a single reflector and lens combination which is reciprocated rapidly along one axis to lengthen and shorten a region of the path of a collimated excitation beam and to form a scan line on a sample. The fluorescence emission may be gathered by the lens of the scan head and directed back, generally along the optical path of the excitation beam, to a detector. Another embodiment of the scanner places the light source, in miniature form, directly on the scan head. The sample may be translated in an axis orthogonal to the scan line in order to stimulate fluorescent emission from a two-dimensional portion of the sample.
