Patent number: 10823825Abstract: A system for generating a 3D image of a scene includes a transmitter, a receiver, a scanning system and a data processing computer. The transmitter includes a pulsed laser generating optical pulses for illuminating the scene, and the optical pulses have a pulse width of less than 20 nanoseconds and a pulse repetition frequency in the range of 20 kHz to 200 kHz. The receiver includes a sensor to detect light scattered and reflected from the scene, and the sensor comprises one or more arrays of Geiger-mode avalanche photodiodes. The scanning system allows the transmitter and receiver subsystem field-of-view (FOV) to interrogate a field-of-regard (FOR) of at least 30 degrees, with update rates faster than once per 5 seconds, resolution higher than 1 million resolution elements per second, and FOR aspect ratios of 1:10 to 1:1. The data processing computer continuously generates 3D point clouds with latency less than 5 seconds, and generates alarms indicating anomalous activity within the scene.Type: GrantFiled: May 1, 2017Date of Patent: November 3, 2020Assignee: 3DEO, INCInventors: Dale G. Fried, Brandon R. Call

Patent number: 10792731Abstract: The present disclosure provides systems and methods for the formation of three-dimensional objects. A method for forming a three-dimensional object may comprise alternately and sequentially applying a stream comprising a binding substance to an area of a layer of powder material in a powder bed, and generating at least one perimeter of the three-dimensional object in the area. The stream may be applied in accordance with a model design of the three-dimensional object. The at least one perimeter may generated in accordance with the model design.Type: GrantFiled: April 30, 2018Date of Patent: October 6, 2020Assignee: 3DEO, INC.Inventors: Payman Torabi, Matthew Petros
