Abstract: The present disclosure relates to a cardiorespiratory analysis system that includes, in at least one embodiment, a conformal patch with a compressible viscoelastic interface and an array of sensors, including, but not limited to a photoplethysmography (PPG) sensor, a 3-axis accelerometer, and an electrocardiogram (ECG) sensor. In at least one embodiment, the system includes a microcontroller wired to the array of sensors. According to at least one embodiment, the system uses computing techniques to derive features from the array of sensors and determines one or cardiorespiratory characteristics of a patient based on the derived features.

Abstract: A positive-working radiation-sensitive composition for use with a radiation source comprises one or more polivinyl acetal polymers capable of being dissolved in an alkaline aqueous solution and a development-enhancing compound. The sensitivity of a radiation-sensitive coating based on the composition of this invention is increased without compromising the handling characteristics. Radiation-sensitive elements based on the composition of the invention have good development latitude. A positive-working lithographic printing precursor is based on the radiation-sensitive composition coated on a hydrophilic surface. The precursor is developable using an alkaline aqueous solution, and may be used with a radiation source in lithographic applications, such as conventional imaging systems, computer-to-plate systems or other direct imaging applications. The precursor is stable in its state before exposure and has an excellent handling property.

Abstract: A positive photosensitive composition for use with a radiation source comprises one or more polymers capable of being dissolved in an alkaline aqueous solution and a compound which, upon being heated, releases gas. The composition is stable in its state before exposure and has an excellent handling property. The sensitivity of a recording layer based on the composition of this invention is increased without compromising the handling characteristics. In addition radiation sensitive-elements based on the composition of the invention have good development latitude.
