Patent number: 11335114Abstract: Some disclosed methods involve acquiring, via an ultrasonic sensor system, first (reference) ultrasonic signals at a first time and acquiring second ultrasonic signals via the ultrasonic sensor system at a second time. Such methods may involve determining, based at least in part on a comparison of the first ultrasonic signals and the second ultrasonic signals, whether one or more layers reside on the cover glass at the second time. If it is determined that the one or more layers reside on the cover glass at the second time, some methods may involve determining one or more signal characteristics corresponding to properties of the one or more layers and determining, based at least in part on the one or more properties, whether the one or more layers are compatible with the ultrasonic sensor system. If so, the method may involve calibrating the ultrasonic sensor system.Type: GrantFiled: August 21, 2020Date of Patent: May 17, 2022Assignee: QUALCOMM IncorporatedInventors: Changting Xu, Soon Joon Yoon, Camilo Perez Saaibi, Hrishikesh Vijaykumar Panchawagh, Kostadin Dimitrov Djordjev

Patent number: 10794827Abstract: Embodiments are generally related to differentiating and/or separating portions of a sample that are of interest from the remainder of the sample. Embodiments may be directed towards separating cells of interest from a cell sample. In some embodiments, acoustic impedances of the cells of interest may be modified. For example, the acoustic properties of the cells of interest may be modified by attaching bubbles to the cells of interest. The cell sample may then be subjected to an acoustic wave. The cells of interest may be differentiated and/or separated from the remainder of the sample based on relative displacements and/or volumetric changes experienced by the cells of interest in response thereto. The cells of interest may be separated using a standing wave and sorted into separate channels of a flow cell. Optionally, the cells may be interrogated by a light source and differentiated by signals generated in response thereto.Type: GrantFiled: April 4, 2017Date of Patent: October 6, 2020Assignee: UNIVERSITY OF WASHINGTONInventors: Thomas Matula, Andrew A.

Patent number: 9956563Abstract: A process for separating clean water which has an impurities content of less than 100 ppm from waste materials such as farm manure is disclosed. In a first step, a plate separator splits the waste material stream into a first effluent fraction and a first solids fraction. The first solids fraction then undergoes two stages of pressing to increase the solids contents to about 30 to 40 percent which makes it suitable for granulation or pelletizing. The first effluent fraction is treated in successive stages with various chemical agents resulting in the removal of most of the solids and inorganic impurities from the effluent to achieve drinkable water purity.Type: GrantFiled: October 21, 2017Date of Patent: May 1, 2018Inventors: Aicardo Roa-Espinosa, Samuel William Roa-Lauby, Kim Huong Pham, Joaquin Camilo Perez-Mahecha
