Abstract: An event camera system for pupil detection may include a camera assembly and a controller, and may also include one or more off-axis light sources. The camera assembly may include one or more infrared (IR) light sources and an event camera. The one or more IR light sources are configured to emit pulses of IR light along an optical path toward an eyebox. The IR light is reflected from an eye in the eyebox, and the reflected light propagates back along the optical path toward the event camera for detection. The controller is configured to determine an orientation of the eye using data output from the event camera.

Abstract: An electric powered steering assembly comprises a housing with a cylindrical portion, an interior wall of the cylindrical portion defining a first and second grooves extending in an axial direction, the first and second grooves having inwardly tapered walls. A ball screw is disposed in the housing, extending in the axial direction, and defining a through hole extending in a radial direction having a first and second ends. A ball nut is disposed in the housing surrounding the ball screw and configured to rotate relative to the housing. A first anti-rotational pin is disposed in the first end of the through hole, a second anti-rotational pin is situated in the second end of the through hole, and a spring is disposed between the anti-rotational pins. The spring is configured to bias the first and second anti-rotational pins in a radially outward direction towards the first and the second groves respectively.

Abstract: A steering system is provided. The steering system includes a housing and a ball shaft translatable relative to the housing. A ball nut is rotatably mounted within the housing. Rotation of the ball nut responsively causes the ball shaft to translate relative to the ball nut and the housing. The ball shaft has an opening extending therethrough. A pin is separate from the ball shaft and inserted into the opening. The pin engages the housing to limit rotation of the ball shaft relative to the housing.

Abstract: An electric commercial vehicle power steering system includes an input shaft, an electric motor, and a planetary gear set, a drive coupling, and an output shaft. A first one of a sun gear, a planet carrier, and a ring gear of the planetary gear set is connected to and rotatable with a rotor of the electric motor, and a second one of the sun gear, the planet carrier, and the ring gear of the planetary gear set is connected to and rotatable with a first gear of the drive coupling. A second gear of the drive coupling is connected to and rotatable with the input shaft. A globoidal worm drive is arranged between the input shaft and the output shaft. The globoidal worm drive couples the input shaft to the output shaft such that the output shaft is rotatable with the input shaft via the globoidal worm drive.

Abstract: An adjustable vascular graft with a user-customizable reduced inner diameter is provided. The graft includes a flexible tubular body having open ends and a plurality of receivers in a sidewall thereof, which may be arranged in two circumferentially spaced rows of receivers. The receivers may take the form of ringlets, eyelets, loops, or holes, which may be provided in a reinforced region of the graft sidewall, and which may be radiopaque. A suture passes through the plurality of receivers, the suture having first and second free ends capable of being pulled, and which suture may also be radiopaque. Tensioning or tightening the first and second ends of the suture reduces an inner diameter of the corresponding portion of the tubular body of the graft, thereby allowing for the custom reduced inner diameter and a resulting flow restriction to be provided. Related methods are also disclosed.

Abstract: A tissue aperture closure device may include more than one suture deployed in multiple directions around a perimeter of a tissue aperture. The sutures may be pulled through a suture lock to tension the sutures and close the tissue aperture. The suture lock may be transitioned between a locked configuration and an unlocked configuration in which the tension of the sutures may be adjusted.

Abstract: Embodiments are related to a system with a headset capable of monitoring psychomotor performance of a user of the headset based on eyelid tracking information. The headset includes a sensor assembly coupled to a frame of the headset, and a transceiver coupled to the sensor assembly. The sensor assembly is configured to track an eyelid of an eye of the user and capture eyelid tracking information. The transceiver is configured to obtain the eyelid tracking information from the sensor assembly and communicate the eyelid tracking information to a secondary device coupled to the headset for processing the eyelid tracking information and determination of sleep information for the user based in part on the processed eyelid tracking information.

Abstract: A device includes a camera assembly and a controller. The camera assembly is configured to capture images of both eyes of a user. Using the captured images, the controller determines a location for each pupil of each eye of the user. The determined pupil locations and captured images are used to determine eye tracking parameters which are used to compute values of eye tracking functions. With the computed values and a model that maps the eye tracking functions to gaze depths, a gaze depth of the user is determined. An action is performed based on the determined gaze depth.

Abstract: Embodiments are related to a plurality of gaze sensors embedded into a frame of a headset for detection of a gaze vector of a user wearing the headset and user's control at the headset. The gaze vector for an eye of the user can be within a threshold distance from one of the gaze sensors. By monitoring signals detected by the gaze sensors, it can be determined that the gaze vector is within the threshold distance from the gaze sensor. Based on this determination, at least one action associated with the headset is initiated.

Abstract: Embodiments are related to a headset integrated into a healthcare platform. The headset comprises one or more sensors embedded into a frame of the headset, a controller coupled to the one or more sensors, and a transceiver coupled to the controller. The one or more sensors capture health information data for a user wearing the headset. The controller pre-processes at least a portion of the captured health information data to generate a pre-processed portion of the health information data. The transceiver communicates the health information data and the pre-processed portion of health information data to an intermediate device communicatively coupled to the headset. The intermediate device processes at least one of the health information data and the pre-processed portion of health information data to generate processed health information data for a health-related diagnostic of the user.
