Patent number: 11747476Abstract: Laser light pulses are generated and scanned in a raster pattern in a field of view. The laser light pulses are generated at times that result in structured light patterns and non-structured light patterns. The structured light patterns and non-structured light patterns may be in common frames or different frames. Time-of-flight measurement is performed to produce a first 3D point cloud, and structured light processing is performed to produce a second 3D point cloud.Type: GrantFiled: April 16, 2019Date of Patent: September 5, 2023Assignee: Microvision, Inc.Inventor: Jari Honkanen

Patent number: 10845469Abstract: Devices and methods are described that provide for scanning surfaces and generating 3-dimensional point clouds that describe the depth of the measured surface at each point. In general, the devices and methods utilize. Specifically, the depth mapping devices and methods utilize multiple receiver channels, with each receiver channel configured to have a different effective sensing range. These multiple receiver channels together provide the depth mapping device with an increased overall effective sensing range. Thus, the depth mapping device can effectively map surfaces that are closer and/or farther than could be mapped using only one receiver channel.Type: GrantFiled: January 8, 2018Date of Patent: November 24, 2020Assignee: Microvision, Inc.Inventors: Jari Honkanen, Robert James Jackson

Patent number: 10671219Abstract: A scanning display system includes smart infrared pulsing to detect gestures and touch events with reduced power consumption. Infrared laser light pulses are emitted at a first density in a field of view and reflections are detected. Times of flight of the infrared laser light pulses are measured to determine if an object is in the field of view. The density of the infrared pulses may be increased based on various factors to detect gestures and touch events. Power consumption is reduced by reducing the density of laser pulses when possible.Type: GrantFiled: February 12, 2018Date of Patent: June 2, 2020Assignee: Microvision, Inc.Inventors: P.

Patent number: 10481739Abstract: Briefly, in accordance with one or more embodiments, an information handling system comprises a scanning system to scan one or more component wavelength beams into a combined multi-component beam in a first field of view, and a redirecting system to redirect one or more of the component wavelength beams into a second field of view. A first subset of the one or more component wavelength beams is projected in the first field of view and a second subset of the one or more component wavelength beams is projected in the second field of view. The first subset may project a visible image in the first field of view, and user is capable of providing an input to control the information handling system via interaction with the second subset in the second field of view.Type: GrantFiled: February 16, 2016Date of Patent: November 19, 2019Assignee: Microvision, Inc.Inventors: P.

Patent number: 10200683Abstract: Devices and methods are described herein for providing foveated image projection. In general, at least one source of laser light is used to generate a laser beam, and scanning mirror(s) that reflect the laser beam into a pattern of scan lines. The source of light is controlled to selectively generate projected image pixels during a first portion of the pattern of scan lines, and to selectively generate depth mapping pulses during a second portion of the pattern of scan lines. The projected image pixels generate a projected image, while the depth mapping pulses are reflected from the surface, received, and used to generate a 3-dimensional point clouds that describe the measured surface depth at each point. Thus, during each scan of the pattern both a projected image and a surface depth map can be generated, with the surface depth map used to modify some portion of the projected pixels.Type: GrantFiled: December 21, 2016Date of Patent: February 5, 2019Assignee: Microvision, Inc.Inventors: P.

Patent number: 9921056Abstract: Devices and methods are described that provide for scanning surfaces and generating 3-dimensional point clouds that describe the depth of the measured surface at each point. In general, the devices and methods utilize scanning mirror(s) that reflect a laser beam into a pattern of scan lines. When the raster pattern of scan lines is directed at a surface, reflections of the laser beam from the surface are received and used to the generate 3-dimensional point clouds that describe the measured surface depth at each point. The motion of the scanning mirror(s) can be dynamically adjusted to modify the characteristics of the resulting 3-dimensional point cloud of the surface. For example, the adjustment of the scanning mirror motion can modify the resolution or data density of the resulting 3-dimensional point cloud that describes the measured depths of the surface.Type: GrantFiled: July 27, 2017Date of Patent: March 20, 2018Assignee: Microvision, Inc.Inventors: Jari Honkanen, P.
