摘要： The present disclosure generally pertains to devices and methods for generating thrust in vehicles, for instance in space applications. A heaterless, insertless hollow cathode utilizes AC and pulsed DC electric fields to ionize the propellant gas and generate a plasma plume. The cathode uses an argon microplasma generated in a quartz tube with a tungsten filament and brass ion collector. Free electrons are then drawn from the plasma plume and supplied to a thruster engine.

摘要： The present disclosure generally pertains to systems and methods for processing optical signals. In some embodiments, an optical system has an optical device for receiving a plurality of optical signals and processing such signals in a desired way. The optical device has one or more functional layers that are separated by buffer layers. The index of refraction of at various points in each functional layer is controlled during manufacturing so that the functional layer performs one or more optical functions or, in other words, manipulates one or more incoming optical signals in a desired way, such as switching, filtering, splitting, focusing, collimating, etc. As an example, the index of refraction profile within a region of a functional layer may be controlled so that an incoming signal from a first optical fiber is redirected for reception by a second optical fiber that is not aligned with the first optical fiber.

摘要： Systems and methods are provided for determining whether and/or when a patient is taking his or her medication and, when appropriate, providing reminders and/or alerts to the patient to improve adherence to a medication regimen. In some embodiments, a medication container is provided that includes a capacitance sensor for sensing the contents of the medication container (e.g., pill count or quantity of liquid medication). The capacitance sensor may include interleaved or interdigitated electrodes oriented vertically, horizontally, or angularly (e.g., diagonally) relative to an axis of the medication container. Reminders and/or alerts to the patient may be triggered based at least in part on the contents of the medication container, when a cap of the container was last opened and/or closed, the location of the medication container, and/or the container's surroundings.

摘要： A triboelectric generator can include respective contact members including a first contact member and second contact member. The respective contact members can be movable with respect to each other such that the respective contact members separate from each other in a first configuration and contact each other in a second configuration. The first contact member can include a first conductive layer and a contact layer. The second contact member can be spaced apart from the first contact member in the first configuration and can include an insulating contact layer and a second conductive layer. The insulating contact layer can be configured to come into contact with the contact layer of the first contact member and the transition of the respective contact members from the first configuration to the second configuration can create triboelectric charges. In some examples, the first contact member can include a non-contact insulating layer.

摘要： A system and method for automatically quantifying mobility of a person performing a mobility diagnostic procedure. In one exemplary embodiment, the system measures a posture change test procedure with integrated inertial, location, and navigation type sensors found in a mobile computing device worn by a patient during the posture change test procedure, such as a timed-up-and-go (TUG) procedure. The measurements captured during the posture change inform a health care provider about the mobility of a patient. For example, a determination about the likelihood of the patient experiencing a fall can be assessed from measurable parameters produced from the inertial, location, and navigation-type sensors.

摘要： A system for eye movement and pupil size change matching for user authentication includes an ocular sensor that is configured to sense eyes of a user and collect data indicative of the user's eye movement and pupil size changes. When a user's eyes are detected, the logic analyzes data collected by the ocular sensor in order to determine whether the sensed data match data extracted from a template defined by the eye movement and pupil size changes of an authorized user. If so, the user is authenticated and is permitted to access at least one restricted resource. As an example, the user may be permitted to access an application or sensitive data stored on a computer system or to access a restricted area, such as a room of a building.

摘要： A fiber optic directional sensor has a substantially hemispherical dome surface and a substantially flat surface. The sensor is formed from a plurality of optical fibers fused to one another, and each optical fiber extends from the dome surface to the flat surface. One end of each optical fiber is substantially perpendicular to the sensor's dome surface, and the opposite end of the fiber is substantially perpendicular to the sensor's flat surface such that an end face of the fiber is substantially tangent to the dome surface, and another end face of the fiber is substantially tangent to the flat surface. Using the sensor, light from projectiles, such as missiles, bullets, and other weaponry, can be detected, and the locations of the projectiles can be determined.

摘要： The present invention relates to a method for the continuous production of low thermal conductivity endless filament yarns with a compact, homogeneous structural morphology. The presently disclosed methods utilize safe and recyclable ionic liquids to produce carbon fiber precursors from cellulose. The fibers are produced by the carbonization of cellulose carbon fiber precursors. The precursor fiber filaments have an increased tear resistance with simultaneously sufficient elongation, a round or crenulated cross-section, and homogeneous fiber morphology. The filament yarns exhibit performance characteristics similar to those produced from traditional viscose rayon. The resulting fibers are especially suited for aerospace applications in composite materials used at the limits of high temperatures, for instance in structures found in rocket nozzles or atmospheric reentry heat shields on spacecraft.

摘要： The present invention relates to a method for the continuous production of low thermal conductivity endless filament yarns with a compact, homogeneous structural morphology. The presently disclosed methods utilize safe and recyclable ionic liquids (IL) to produce carbon fiber precursors from cellulose. The fibers are produced by the carbonization of cellulose carbon fiber precursors. The precursor fiber filaments have an increased tear resistance with simultaneously sufficient elongation, a round or crenulated cross-section, and homogeneous fiber morphology. The filament yarns exhibit performance characteristics similar to those produced from traditional viscous rayon. The resulting fibers are especially suited for aerospace applications in composite materials used at the limits of high temperatures, for instance in structures found in rocket nozzles or atmospheric reentry heat shields on spacecraft.
