    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: Apparatuses and associated methods of manufacturing are described that provide for cut-resistant yarn structures. An example cut-resistant yarn structure includes a first cut-resistant core filament a second cut-resistant core filament. The yarn structure further includes a first covering yarn that is wound over the first cut-resistant core filament and the second cut-resistant core filament. The first covering yarn includes a core-spun yarn in which staple fibers are spun over a third cut-resistant core filament. The yarn structure also includes one or more covering layers wound over the first covering yarn that may serve as the exterior layer for the cut-resistant yarn structure. In some instances, the first and second cut-resistant core filaments include a core-spun yarn in which staple fibers are spun over the first cut-resistant core filament and/or the second cut-resistant core filament.

    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.

    Abstract: The cut-resistant yarn structure(130,170) comprises a core-spun yarn (135)comprising a first cut-resistant core filament (132) and staple fibers(134)spun over the first cut-resistant core filament(132), a covering yarn(139) comprising a second cut-resistant core filament (136) and a first covering layer (138) wound over the second cut-resistant core filament (136), where the first covering layer (138) comprises a first filament and a second covering layer(140) wound over the core-spun yarn(135)and the covering yarn(139), where the second covering layer(140) comprises a second filament. The cut-resistant composite yarn structure can be used to manufacture cut-resistant cloth which may in turn be used to manufacture cut-resistant garments such as cut-resistant gloves, cut-resistant sleeves and other cut-resistant garments.
