  • Publication number: 20200000169
    Abstract: A garment worn by a wearer has an exterior shell and an interior shell with various impact absorbing material between the exterior shell and the interior shell. The impact absorbing material includes multiple structures, such as rods or filaments, capable of deforming when force is applied then returning to its state prior to application of the force. In various embodiments, a rate sensitive material (RSM) is positioned in one or more locations relative to the exterior shell and the interior shell of the garment to further attenuate impacts to the garment. The RSM changes its resistance to force based on a rate at which the material is loaded.

  • Patent number: 10413710
    Abstract: Drainage systems for excess body fluids and associated methods are disclosed herein. A drainage system in accordance with an embodiment of the present technology can include, for example, a drainage catheter, a first reference line, a second reference line, and a pressure sensor assembly. The catheter can include a flexible interface member and an inlet can be placed in fluid communication with a site of excess body fluid within a patient. A first flexible region of the first reference line can be in pressure communication with the flexible interface member, and a second flexible region of the second reference line can be in pressure communication with the surrounding atmosphere. The pressure sensor assembly can be spaced apart from the flexible regions, and measure the pressures of the first and second reference lines. This information can be used to determine the pressure at the site of excess body fluid.

  • Publication number: 20190134277
    Abstract: Neurological implants whose surfaces have been chemically and covalently modified to impart beneficial properties to the neurological implants are described. The neurological implants possess improved biocompatibility compared to a corresponding neurological implant that lacks the chemical modification. Following implantation in a subject, the surface-modified neurological implants induce a lower-foreign body response, compared to a corresponding unmodified product.

  • Publication number: 20190126018
    Abstract: Drainage systems for excess body fluids and associated methods are disclosed herein. A body fluid drainage system in accordance with an embodiment of the present technology, for example, can include a catheter that has an exterior surface, a proximal portion, and a distal portion opposite the proximal portion. The body fluid drainage system can further include a valve device, a pressure sensor, and a controller operatively coupled to the valve device and the pressure sensor. The valve device can include an actuator positioned over the exterior surface of the catheter. The actuator is movable between an open position that allows body fluid flow through the catheter, a closed position that at least substantially obstructs the body fluid flow through the catheter, and intermediate positions that partially obstruct the body fluid flow through the catheter. The controller can change the position of the actuator in response to a predetermined condition of the pressure sensor.

  • Publication number: 20170209056
    Abstract: Self-calibrating sensor assemblies for excess body fluid drainage systems are disclosed herein. Self-calibrating sensor assemblies can include a sensor assembly engaged with a flexible interface member of a drainage catheter. The assembly includes a sensor having a body and a shaft extending from the body. A contact member is slidably mated with the shaft and coupled to the flexible interface member. A resilient member is coupled to the sensor shaft and disposed between the contact member and the body. An actuator moves the sensor between a first position and a second position with respect to the drainage catheter. In the first position the sensor is positioned to measure the pressure and/or force at the flexible interface member, and in the second position the resilient member exerts a known force on the sensor.

    Abstract: The present technology relates generally to protective helmets with non-linearly deforming members. Helmets configured in accordance with embodiments of the present technology can comprise, for example, an inner layer, an outer layer, a space between the inner layer and the outer layer, and an interface layer disposed in the space. The interface layer comprises a plurality of filaments, each having a height, a longitudinal axis along the height, a first end proximal to the inner layer, and a second end proximal to the outer layer. The filaments are sized and shaped to span the space between the inner layer and the outer layer. The filaments are configured to deform non-linearly in response to an external incident force on the helmet.
