Patent number: 11287521Abstract: System and methods for obtaining sizing of an irregularly shaped object. The methods comprise: displaying, by a display of a handheld scanner system, a 3D optical figure of a subject; displaying a grid superimposed over the 3D optical figure of the subject, the grid comprising a plurality of marks arranged in rows and columns; generating, by a radar module of the handheld scanner system, range data specifying a sensed spacing between the radar module and at least a surface of a first portion of the irregularly shaped object which is covered by at least one item; receiving, by a processor of the handheld scanner system, the range data from the radar module as the subject is being scanned; and causing at least one first visual characteristic of a first mark of said plurality of marks to change when corresponding range data is successfully received by the processor.Type: GrantFiled: July 14, 2020Date of Patent: March 29, 2022Assignee: BODIDATA, INC.Inventors: Albert Charpentier, Michael Boylan, Tuoc Luong, Hoa V. Pham, Long Nguyen, Hai Nguyen, Tung V. Vu

Publication number: 20190295319Abstract: Systems and methods for generating a refined 3D model. The methods comprise: constructing a subject point cloud using at least optical camera data acquired by scanning a subject; using radar depth data to modify the subject point cloud to represent an occluded portion of the subject's real surface; generating a plurality of reference point clouds using (1) a first 3D model of a plurality of 3D models that represents an object belonging to a general object class or category to which the subject belongs and (2) a plurality of different setting vectors; identifying a first reference point cloud from the plurality of reference point clouds that is a best fit for the subject point cloud; obtaining a setting vector associated with the first reference point cloud; and transforming the first 3D model into the refined 3D model using the setting vector.Type: ApplicationFiled: March 14, 2019Publication date: September 26, 2019Inventors: Hoa V.

Patent number: 10156479Abstract: Systems, methods and other embodiments associated with spatial-domain Low-coherence Quantitative Phase Microscopy (SL-QPM) are described herein. SL-QPM can detect structural alterations within cell nuclei with nanoscale sensitivity (0.9 nm) (or nuclear nano-morphology) for “nano-pathological diagnosis” of cancer. SL-QPM uses original, unmodified cytology and histology specimens prepared with standard clinical protocols and stains. SL-QPM can easily integrate in existing clinical pathology laboratories. Results quantified the spatial distribution of optical path length or refractive index in individual nuclei with nanoscale sensitivity, which could be applied to studying nuclear nano-morphology as cancer progresses. The nuclear nano-morphology derived from SL-QPM offers significant diagnostic value in clinical care and subcellular mechanistic insights for basic and translational research. Techniques that provide for depth selective investigation of nuclear and other cellular features are disclosed.Type: GrantFiled: December 5, 2014Date of Patent: December 18, 2018Assignee: University of Pittsburgh—Of the Commonwealth System of Higher EducationInventors: Yang Liu, Randall E. Brand, Hoa V. Pham, Shikhar Fnu

Patent number: 4967311Abstract: A system interconnects electronic modules with one another, to a power supply and to signal lines through a printed circuit board. The modules are electrically connected to traces on the printed circuit board using blind mateable connectors. EMI shielding plates are mounted to the circuit board at the I/O connectors for the external cables. Guide elements, such as pin and socket guides and printed circuit board edge guides, are mounted to the circuit board to guide the blind mateable connectors. The syustem eliminates the numerous cables which would otherwise be required. The printed circuit board is mounted within the system housing and acts as an air duct barrier to aid proper air circulation. The circuit board also acts as a structured element helping to stabilize the housing and various module supports and serves as a mounting structure for various elements, such as cooling fans.Type: GrantFiled: July 31, 1989Date of Patent: October 30, 1990Assignee: Tandem Computers IncorporatedInventors: Joerg U. Ferchau, Hoa V. Pham, Randall J. Diaz
