Systems and methods of detecting pupillary positions on a head of a subject are described. While a camera and a light source are positioned in front of the head of the subject, the camera is caused to capture image data representative of a frontal portion of the head of the subject. From the image data, a face of the subject is detected. Up to two eyes are identified from the detected face. A reflection of the light source on each identified eye is detected. A pupillary position of each identified eye is estimated based on a position of the detected light source reflection on the identified eye. One or more of interpupillary distance, left pupil distance, and right pupil distance may be determined from the estimated pupillary positions.

METHOD AND SYSTEM FOR PROJECTING AN IMAGE WITHIN AN EYE SAFETY LIMIT
A system includes a light source to generate a source light, a spatial modulator to receive the source light. a display element to receive the source light from the spatial modulator and to direct the source light towards an eye, and a controller. The controller is to receive initial image data for an image to be displayed, the image comprising a plurality of pixels having a plurality of brightness levels, determine an image power based on the brightness levels, and determine an excess power status based on a comparison of the image power to a specified power threshold. Responsive to the excess power status indicating the image power is to exceed the specified power threshold, the controller is to reduce the brightness levels to generate updated image data, and control the light source and the spatial modulator to project the image using the updated image data.

Systems, devices, and methods for optical engines and laser projectors that are well-suited for use in wearable heads-up displays (WHUDs) are described. Generally, the optical engines integrate a plurality of laser diodes (e.g., 3 laser diodes, 4 laser diodes) within a single, hermetically or partially hermetically sealed, encapsulated package. Photonic integrated circuits having grating or edge couplers may be used to combine beams of light emitted by the plurality of laser diodes. A waveguide medium having one or more directly written waveguides may couple light from laser diodes to a photonic integrated circuit, and may optionally hermetically or partially hermetically seal the laser diodes, eliminating the need for a separate seal. WHUDs that employ such optical engines and laser projectors are also described.

A mechanical pipe coupling is formed of segments attached end to end to surround a central space. Each segment has arcuate keys which project toward the central space. Each key is formed of a pair of side surfaces and a mid surface between them. The mid surface is angularly oriented relative to a longitudinal axis perpendicular to a plane containing the segments. When used to couple pipe elements having grooves the angular orientation of the mid surfaces provides flexibility to the joint. A method of joining pipe elements end to end is also disclosed.
