Abstract: Provided are drain cover devices that include a light emitting diode. The light emitting diode exhibits an average radiant light intensity, a wavelength, or both, configured for killing, destroying, rendering inert, rendering non-infectious, or a combination thereof, a pathogen, a fungi, a toxin, or a combination thereof. Drain cover devices include a housing having a top exhibiting a first diameter, a top surface, and an underside, bottom component, and a drain adapter. The bottom component is affixed to the underside of the top component and includes a bottom surface defining a bottom component central aperture and a second diameter. The drain adapter is affixed to the bottom component and defines a drain adapter and a central aperture, and the top and bottom component define a central volume. An electronic circuit board having the light emitting diode is disposed within the central volume.

Abstract: A system can include: a neural input/output device (NIOD) implanted in a user; a real-time engine communicatively coupled with the NIOD; and a three-dimensional (3D) object communicatively coupled with the NIOD.

Abstract: A method can include: acquiring via one or more electromyography (EMG) sensors in electrical contact with a patient, one or more electrical signals; mapping the one or more electrical signals to one or more intended movements via an EMG signal classifier; applying the one or more intended movements to a simulated body region; and rendering a movement of the simulated body region using a virtual reality (VR) display device.

Abstract: A gas-driven, pressure-regulated ventilator (10, 210) provides support for spontaneous breathing and non-breathing patients. The ventilator provides short pressure cycled and constant flow ventilatory support that allows the patient to receive consistent and reliable ventilatory breaths. The ventilator is designed to allow a clinician to adjust Peak Inspiratory Pressure (PIP) and Positive End Expiratory Pressure (PEEP) values and the duration of inhalation and exhalation flows in a breath cycle to accommodate patient-specific ventilation needs.

Abstract: A method can include: mapping an avatar of a user to a physical body of the user; representing a target area of pain, injury, or disease within the avatar; applying a visual therapy to the target area; and the targeted area responding to the visual therapy.
