Abstract: A display system comprises a wearable display device for displaying augmented reality content. The display device comprises a display area comprising light redirecting features that are configured to direct light to a user. The display area is at least partially transparent and is configured to provide a view of an ambient environment through the display area. The display device is configured to determine that a reflection of the user is within the user's field of view through the display area. After making this determination, augmented reality content is displayed in the display area with the augmented reality content augmenting the user's view of the reflection. In some embodiments, the augmented reality content may overlie on the user's view of the reflection, thereby allowing all or portions of the reflection to appear to be modified to provide a realistic view of the user with various modifications made to their appearance.

Abstract: In some embodiments, a display system comprising a head-mountable, augmented reality display is configured to perform a neurological analysis and to provide a perception aid based on an environmental trigger associated with the neurological condition. Performing the neurological analysis may include determining a reaction to a stimulus by receiving data from the one or more inwardly-directed sensors; and identifying a neurological condition associated with the reaction. In some embodiments, the perception aid may include a reminder, an alert, or virtual content that changes a property, e.g. a color, of a real object. The augmented reality display may be configured to display virtual content by outputting light with variable wavefront divergence, and to provide an accommodation-vergence mismatch of less than 0.5 diopters, including less than 0.25 diopters.

Abstract: A decoupled mono tube damper assembly for a vehicle includes an outer tube attached to the vehicle's unsprung mass. The outer tube has a base and a sleeve end. An outer tube sleeve engaging end of an inner tube is slidingly engaged with the sleeve end. The inner tube has an end distal to the sleeve engaging end, and is attached to the vehicle's sprung mass at the distal end. A damper rod has one opposed end extending axially into a base aperture, and an opposed end connecting to the inner tube. The rod moves axially relative to the outer tube, due to forces transmitted from the unsprung mass. A low amplitude energy-managing member is operatively disposed within the outer tube, and has a throughbore receiving the rod. A travel-limiting member attaches to the rod and is engageable with the energy-managing member. The travel-limiting member constrains axial movement of the rod through the outer tube base to a predetermined limit.

Abstract: The ability of a damper to attenuate smooth road shake in a vehicle is tested using a test fixture that is controlled by inputting data for periodic low amplitude periodic excitations having a selected frequency range, selected amplitude range and a selected dither representative of vehicle operation on relatively smooth roads. The selected frequency range is about 5 Hz to 30 Hz and the selected amplitude range is about 0.05 mm to 2.00 mm. A preferred frequency is about 15 Hz which is applied preferably for about 200 cycles in a series of separate tests at individual amplitudes of, for example, 0.05, 0.10, 0.15, 0.20, 0.25, 0.50, 1.00 and 2.00 mm. The damper is tested to produce low amplitude test results comprising displacement, force and velocity parameters, measured as functions of time.

Abstract: Dampers for vehicle suspensions include a housing comprising a tube attached to a wheel axle of a vehicle and a piston rod extending from a piston within the tube and attached to the vehicle body. The piston divides the tube into first and second chambers. In order to damp responses when minor smooth road imperfections impart low force excitations to the wheel of the vehicle, a fluid bypass passageway in the form of a sleeve is positioned around the tube and overlies the piston. This provides second stage quasi-ideal damping at low force excitations to the wheels and thus to the wheel axles of the vehicle. The sleeve communicates with the first and second chambers through metered orifices or valves. As low force excitations from smooth road imperfections displace fluid within the tube through the metered orifices or valves, the orifices damp responses to the low force excitations, thereby smoothing the ride of the vehicle.
