Abstract: An exercise device for glute hamstring exercises is herein disclosed. The exercise device includes a support base and a retractable pad assembly. The support based includes a knee pad supported by two side rails, with the knee pad and two side rails defining a recessed portion. The retractable pad assembly includes a lower bar designed to engage a floor or other surface. The support bar is pivotally coupled to the lower bar. A fitness pad is coupled to the support bar. The retractable pad assembly is slidably coupled to the support base between: (1) a collapsed position wherein the lower bar and the support bar are disposed in the recessed portion and (2) an extended position wherein the lower bar and the support bar extend out of the recessed portion.

Abstract: A concrete mix, including: cementitious content between 25 and 200 kg/m3; fly ash content between 25 and 175 kg/m3; dirty sand with fine aggregates between 3% and 20%; water content between 150 I/m3 and 250 l/m3; and a chemical admixture comprising one or more components selected from the following: an acrylic, formaldehyde-free polymer-based admixture, modified in aqueous solution; a surfactant admixture configured to entrain micro air bubbles in concrete; and an organic polymer comprising hydrophilic groups for increasing the viscosity of the mixture.

Abstract: An inventive method and system are provided for identifying a compatible photoplethysmographic sensor when interconnected to a given photoplethysmographic monitor. The method and system may further provide for the identification of which of a plurality of compatible sensors is interconnected to allow for selective calibration of the photoplethysmographic monitor. In this regard, the system and method may entail provision of a predetermined drive or test signal to a light source and/or identification element (i.e., sensor elements) of a photoplethysmographic sensor, and the obtainment of a corresponding output signal for use in sensor identification. In one approach, an output signal is obtained from at least one of three sensor elements each of which is interconnected between a different pair of sensor terminals which is a unique combination of two of four sensor terminals on the sensor.

Abstract: The invention is directed to a disposable oximetry sensor having an integrally formed connector. In one aspect, the sensor includes a clear flexible substrate on which a light emitter and/or light detector (collectively active component(s)) are mounted to allow those components to emit/detect light though the clear substrate and a second patient-side surface of that substrate. The clear substrate will generally contain one or more electrically conductive traces, preferably formed through a printing process, for interconnection to the active components. In this regard, the clear substrate acts as the electrical connector and lens structure for the active components reducing the overall part count for the sensor's assembly. Additional materials/layers may be added to the sensor including an adhesive layer, a compressible material layer, a light blocking layer, and/or a heat sink for thermal management.
