Patent number: 11921238Abstract: A method of lidar imaging pulses a scene with laser pulse sequences from a laser light source. Reflected light from the scene is measured for each laser pulse to form a sequence of time resolved light signals. Adjoining time bins in the time resolved light signals are combined to form super time bins. A three dimensional image of the scene is created from distances determined based on maximum intensity super time bins. One or more objects are located within the image. For each object, the time resolved light signals are combined to form a single object time resolved light signal from which to determine distance to the object.Type: GrantFiled: May 17, 2019Date of Patent: March 5, 2024Assignee: THE CHARLES STARK DRAPER LABORATORY, INC.Inventors: Joseph Hollmann, Zachary R.

Patent number: 11872702Abstract: Embodiments provide functionality to prevent collisions between robots and objects. An example embodiment detects a type and a location of an object based on a camera image of the object, where the image has a reference frame. Motion of the object is then predicted based on at least one of: the detected type of the object, the detected location of the object, and a model of object motion. To continue, a motion plan for the robot is generated that avoids having the robot collide with the object based on the predicted motion of the object and a transformation between the reference frame of the image and a reference frame of the robot. The robot can be controlled to move in accordance with the motion plan or a signal can be generated that controls the robot to operate in accordance with the motion plan.Type: GrantFiled: September 13, 2019Date of Patent: January 16, 2024Assignee: The Charles Stark Draper Laboratory, Inc.Inventors: David M.

Patent number: 11762062Abstract: A LiDAR system emits single mode light from a photonic integrated circuit (PIC) and is capable of receiving a different mode light, or multiple modes of light, into the PIC. Objects in the LiDAR's field of view may reflect light with a mode different from the mode of the light that illuminated the objects. Thus, in some embodiments, a single-mode optical waveguide, a single-mode-multi-mode optical junction, a multi-mode optical waveguide and an array of optical emitters on the PIC are configured to emit into free space light of a single mode from each optical emitter of the array of optical emitters. The multi-mode optical waveguide and the array of optical emitters are configured to receive from the free space light of a mode different from the single mode, or multiple modes, and to couple the light of the different mode or multiple modes into the multi-mode optical waveguide.Type: GrantFiled: May 5, 2021Date of Patent: September 19, 2023Assignee: The Charles Stark Draper Laboratory, Inc.Inventors: Steven J.

Patent number: 11760967Abstract: This disclosure provides systems and methods for seeding cell cultures in a microfluidic device. The systems and methods of this disclosure can enable flow of a cell solution from one side of a scaffold, such as a porous substrate or membrane, to the other side of the scaffold. Flow of the liquid can pass through the scaffold while the cells themselves do not, resulting in the cells driven to the surface of the scaffold for consequent attachment. A microfluidic device can include a microfluidic feature structured to create a seal between a cell seeding tool and an inlet to a microchannel of the microfluidic device. This can enable a pressure-driven flow to push fluid down the channel and through pores of the membrane. In contrast, traditional gravity fed seeding of cells may not create enough pressure to drive fluid through the pores of the scaffold.Type: GrantFiled: September 4, 2020Date of Patent: September 19, 2023Assignee: Charles Stark Draper Laboratory, Inc.Inventors: Hesham Azizgolshani, Brian Cain, Joseph Charest, Jonathan Robert Coppeta, Brett Isenberg, Timothy Petrie
