Abstract: A head-mounted display (HMD) determines whether a set of criteria is satisfied based on eye-related readings collected by a camera of the HMD and wirelessly transmits a set of messages in response to a determination that the set of criteria is satisfied. An attachment includes a set of light-emitting diodes (LEDs) and activates the set of LEDs to emit the light at the bleaching intensity in response to receiving the set of messages.

Abstract: A head-mounted display and accessory system in which the accessory emits bleaching light through the head-mounted display to bleach photoreceptors for dark adaptation testing includes a casing, where a lens of a head-mounted display is positioned inside the cavity, and where an aperture of the casing is aligned with an exterior-facing camera of the head-mounted display. The system also includes an attachment body, where a posterior end of the attachment body is fixed to an anterior end of the casing, and where the attachment body includes a set of light-emitting diodes (LEDs), where the set of LEDs is attached to the posterior end of the attachment body and is directed towards the lens. The system also includes a circuitry that is configured to control light emission of the set of LEDs.

Abstract: Valves and valve assemblies are described herein employing architectures which can mitigate degradative wear mechanisms, thereby prolonging life of the assembly. In one aspect, a valve comprises a head including a circumferential surface and a valve seat mating surface comprising sintered cemented carbide. Leg members extend from the head, wherein thickness of one or more of the leg members tapers in a direction away from the head to induce laminar fluid flow around the head. In some embodiments, the sintered cemented carbide is an inlay coupled to the valve head.

Abstract: An ophthalmic imaging system has a specialized graphical user interface GUI to convey information for manually adjusting control inputs to bring an eye into alignment with the device. The GUI provides additional information such as laterality, visual alignment overlay aids, and live video feeds. The system further applies automatic gain control to fundus images, synchronizes itself with other ophthalmic systems on a computer network, and provides an optimized image load and display system.

Abstract: An ophthalmic imaging system provides an automatic focus mechanism based on the difference of consecutive scan lines. The system also provides of user selection of a focus point within a fundus image. A neural network automatically identifies the optic nerve head in an FA or ICGA image, which may be used to determine fixation angle. The system also provides additional scan tables for multiple imaging modalities to accommodate photophobia patients and multi-spectrum imaging options.

Leg members extend from the head, wherein thickness of one or more of the leg members tapers in a direction away from the head to induce laminar fluid flow around the head. The valve can also comprise a seal coupled to the circumferential surface of the head. In some embodiments, an exterior surface of the seal exhibits a radius of curvature maintaining laminar fluid flow around the valve. Additionally, the seal can overlap a portion of the valve seat mating surface, in some embodiments.

Abstract: The disclosed system, device and method for an electric motor generally includes a hollow shaft having a first end and a second end. An electromagnet is coupled to the hollow shaft, where the electromagnet is suitably configured to emit an electromagnetic field, and where the electromagnet is disposed between the first end and the second end of the hollow shaft. A drum substantially encases the electromagnet, where the drum is coupled to rotate about an axis of the hollow shaft in response to the electromagnetic field emitted by the electromagnet.
