Patent number: 11966826Abstract: One or more default protected attribute values may be determined for a prediction model trained based on training data including a plurality of training observations. Each of the plurality of training observations may include a respective plurality of training data values corresponding with a plurality of features. Each of the plurality of training observations may also include a respective target value. Each of the plurality of training observations may include a respective protected attribute value corresponding with a protected attribute feature. A request to determine a designated predicted target value for a designated inference observation may be received after determining the one or more default protected attribute values. The predicted target value may be determined by applying the prediction model to an inference observation and a designated default protected attribute value of the one or more default protected attribute values.Type: GrantFiled: November 14, 2022Date of Patent: April 23, 2024Assignee: Epistamai LLCInventor: Christopher Lam

Patent number: 11941107Abstract: Some examples described herein relate to computer interfaces and authentication protocols for securely linking and transferring content between online accounts. In one example, a system can provide a graphical user interface (GUI) with multiple interactive interface pages, through which a user can selectively transfer content from a first online account to a second online account. For example, the user can select to transfer points from the first online account to the second online account. The system can then transfer of the selected content from the first online account to the second online account. To perform this transfer, the system can employ multiple layers of authentication and other security mechanisms. For example, the system can employ two or more layers of authentication and a unique external identifier to perform the transfer. Following the transfer, the GUI can be updated to reflect the results of the transfer.Type: GrantFiled: September 15, 2023Date of Patent: March 26, 2024Assignee: Starbucks CorporationInventors: Ita Eddie Wang, Christopher Estes, Ehudes Fernan Garcia Gil, Krishna Sumanth Chagarlamudi, Hou Lam, Fernando Augusto Alvarez Medina, Clayton Timothy Brandt

Publication number: 20240074657Abstract: The subject invention pertains to a novel angle-closure detection method for risk assessment of primary angle closure (PAC) or primary angle closure glaucoma (PACG) to inform treatment decisions. According to certain embodiments, a plurality of cross-sectional images of the anterior segment of an eye centered at the pupil with preferably even radial separations are obtained from optical coherence tomography imaging. After identifying the position of scleral spur from the cross-sectional image captured at each angle-location, the anterior chamber angles are analyzed. Each angle-location of the eye is classified as (i) closed angle, (ii) narrow angle, or (iii) open angle. The extents of narrow angles and closed angles among all angle-locations across the 360° radial space are computed. Based on the extents of narrow angles and closed angles, a regression model is applied to compute the risk of PAC/PACG development.Type: ApplicationFiled: August 25, 2023Publication date: March 7, 2024Inventors: Kai-Shun Christopher LEUNG, Ka-Ngai Alexander LAM, Yawen Philip GUO

Patent number: 11922195Abstract: Some embodiments support embedding of a notebooks software component in a surrounding host application, thereby promoting consistency of notebook user interfaces and user experiences between different kinds of applications. For instance, the notebook access added to an integrated development environment (IDE) may be aesthetically consistent with the notebook access added to a business analytics tool from the same vendor as the IDE. Departures from the aesthetic are still supported, e.g., a notebook access provided in a video gaming environment to teach gamers programming skills may have the same aesthetic as the simulated world of the video game, rather than an IDE aesthetic or an enterprise software aesthetic. Direct integration or proxied integration architectures may be used. Efficiencies may be gained by distinguishing between notebook viewing, editing, and executing operations, and providing more computationally expensive resources only as needed for the notebook access being performed.Type: GrantFiled: April 7, 2021Date of Patent: March 5, 2024Assignee: Microsoft Technology Licensing, LLCInventors: John Francis Lam, Safia Abdalla, Shibani Raj Basava, Dinesh Chandnani, Zhu Chen, Kwangje Cho, Ram Kumar Donthula, Katherine Kampf, Daniel Moth, Andrew Christopher Neil, Vaishnavi Sannidhanam, Barry Manh Tu, Vijaya Krishna Upadya, Dileep Yavanmandha

Patent number: 6806786Abstract: Techniques to select the proper frequency band for use in a PLL from among multiple frequency bands of a multi-band VCO. The PLL comprises a detector, a loop filter, the multi-band VCO, and a control unit. The detector receives a first signal to be locked to and a second signal that is related to a VCO signal and provides a detector output. The loop filter filters the detector output to provide a control signal. The multi-band VCO selects one of the multiple frequency bands based on a select signal and provides the VCO signal at a frequency determined by the control signal. The control unit derives the select signal for the multi-band VCO based on information extracted from a third signal (e.g., a filtered version of the control signal) and a timing signal from a timer unit.Type: GrantFiled: May 9, 2002Date of Patent: October 19, 2004Assignee: RF Micro Devices, Inc.Inventors: Christopher Lam, Thai Nguyen, Chet Sooraparth
