Abstract: Devices, apparatuses, methods, and computer program products are provided for hemorrhage detection. An example sensing device for hemorrhage detection includes a blood detection layer that includes a permeable film and one or more optical fibers supported by the permeable film. The device also includes an optical sensor that includes a light source that emits light and an optical receiver in optical communication with the light source via the one or more optical fibers. The optical receiver generates optical data responsive to the light emitted by the light source and received by the optical receiver via the one or more optical fibers indicative of at least a wavelength of the light. The device further includes a controller operably coupled with the optical sensor that receives the optical data generated by the optical receiver in response to the emitted light and determines an amount of blood based upon the optical data.

Abstract: Embodiments relate generally to absorbing elements in respiratory face masks. Applicants have developed a structure for respiratory masks that can both absorb moisture from the face (such as perspiration, as well as from condensed moisture in the breath), and maintain a low breath resistance (won't increase the breath resistance significantly). The structure may comprise an annular structure added to the respiratory masks for moisture management, wherein the annular structure comprises moisture absorbent materials. This structure may also be known as an absorbing element operable to absorb moisture effectively, provide a respiratory mask with improved moisture control characteristics, reduce fogging of a face shield or eyeglasses of the wearer, and reduce the amount of uncomfortable moisture buildup on the face of the wearer.

Abstract: Methods, apparatuses, and systems for determining a concentration of a target gas in a sample gas. An example method of preparing a replaceable testing material for detecting a target gas in a sample gas may include preparing a solution comprising a solute and a solvent, wherein the solute comprises o-tolidine; introducing a testing material substrate to the prepared solution for a period of time; and removing at least a portion of the solvent from the testing material substrate such that the testing material substrate comprises at least a portion of the o-tolidine, and thereby forming the replaceable testing material for detecting the target gas in the sample gas.

Abstract: Devices, apparatuses, methods, and computer program products are provided for hemorrhage detection. An example sensing device for hemorrhage detection includes a blood selective layer that includes a permeable film and an iron selective conductive circuit supported by the permeable film. The sensing device further includes a controller operably coupled with the blood selective layer. The controller is configured to supply a current to the iron selective conductive circuit, determine an impedance of the iron selective conductive circuit responsive to blood received by the blood selective layer, and determine an amount of blood received by the blood selective layer based upon the determined impedance. The controller may further compare the determined impedance with an alert threshold and generate an alert signal in an instance in which the determined impedance satisfies the alert threshold.
