Patent number: 11644682Abstract: A novel class of imaging systems that combines diffractive optics with 1D line sensing is disclosed. When light passes through a diffraction grating or prism, it disperses as a function of wavelength. This property is exploited to recover 2D and 3D positions from line images. A detailed image formation model and a learning-based algorithm for 2D position estimation are disclosed. The disclosure includes several extensions of the imaging system to improve the accuracy of the 2D position estimates and to expand the effective field-of-view. The invention is useful for fast passive imaging of sparse light sources, such as streetlamps, headlights at night and LED-based motion capture, and structured light 3D scanning with line illumination and line sensing.Type: GrantFiled: February 18, 2021Date of Patent: May 9, 2023Assignee: Carnegie Mellon UniversityInventors: Matthew O'Toole, Mark Sheinin, Srinivasa Narasimhan

Patent number: 11630569Abstract: Internet of Things (“IoT”) appliances are gaining consumer traction, from smart thermostats to smart speakers. These devices generally have limited user interfaces, most often small buttons and touchscreens, or rely on voice control. Further, these devices know little about their surroundings—unaware of objects, people and activities around them. Consequently, interactions with these “smart” devices can be cumbersome and limited. The present invention presents an approach that enriches IoT experiences with rich touch and object sensing, offering a complementary input channel and increased contextual awareness. The present invention incorporates a range sensing technology into the computing devices, providing an expansive ad hoc plane of sensing just above the surface with which a device is associated. Additionally, the present invention can recognize and track a wide array of objects, including finger touches and hand gestures.Type: GrantFiled: February 20, 2020Date of Patent: April 18, 2023Assignee: CARNEGIE MELLON UNIVERSITYInventors: Christopher Harrison, Gierad Laput
