Abstract: The present invention relates to a Vertical-Cavity Surface-Emitting Laser (VCSEL) die comprising a VCSEL array configured for flip chip bonding to a substrate with the VCSEL array being designed for emission from a substrate side of the chip, integrated beam shaping optics and electrical contacts including a top surface contact and an etched metal connection through a top mirror structure to a bottom n-mirror, or to an n-doped buffer layer under the bottom n-mirror or to the substrate. The invention further relates to an assembly comprising the above VCSEL die and a photodetector in which the VCSEL die is attached to a circuit board or sub-mount with a solder or bump bonds on the VCSEL die and the photodetector is placed on a same circuit board or sub-mount right next to the VCSEL die.

Abstract: Systems and methods disclosed herein include an illumination module for 3D sensing applications. The illumination module may include an array of vertical cavity surface emitting lasers (VCSELs) emitting light, a driver configured to provide current to the array of VCSELs, and an optical element configured to receive the light emitted by the array of VCSELs and output a light pattern from the illumination module.

Abstract: A method to improve the efficiency of the detection and tracking of machine-readable objects is disclosed. The properties of image frames may be pre-evaluated to determine whether a machine-readable object, even if present in the image frames, would be likely to be detected. After it is determined that one or more image frames have properties that may enable the detection of a machine-readable object, image data may be evaluated to detect the machine-readable object. When a machine-readable object is detected, the location of the machine-readable object in a subsequent frame may be determined based on a translation metric between the image frame in which the object was identified and the subsequent frame rather than a detection of the object in the subsequent frame. The translation metric may be identified based on an evaluation of image data and/or motion sensor data associated with the image frames.

Abstract: Embodiments relate to systems and methods for delivery of oxygen or other treatment gases to a patient without requiring physical contact or enclosure of the patient. Embodiments can include a delivery hood, sensing components, and a gas distribution system including one or more gas delivery ports. Gas delivery ports may be individually controlled based on input from the sensing components to alter the volume and orientation of treatment gas flow directed at a patient. Sensing components can include cameras or other sensors that detect the position of a patient's head, and gas delivery ports may then be controlled to direct treatment gas flow in the direction of the patient's head. Embodiments and methods described thereby allow for efficient oxygen or other gas delivery to a patient without requiring contact or enclosure of the patient.
