Patent number: 11928157Abstract: A constraint system enforces projection constraints on data values stored in specified columns of a shared dataset when queries are received by a database system. A projection constraint identifies that the data in a column may be restricted from being projected (e.g., presented, read, outputted) in an output to a received query, while allowing specified operations to be performed on the data and a corresponding output to be provided. For example, the projection constraint may indicate a context for a query that triggers the constraint, such as based on the user that submitted the query. Enforcing projection constraints on queries received at the database system allows for data to be shared and used anonymously by entities to perform various operations without the need to tokenize the data.Type: GrantFiled: September 23, 2022Date of Patent: March 12, 2024Assignee: Snowflake Inc.Inventors: Khalid Zaman Bijon, Thierry Cruanes, Simon Holm Jensen, Allison Waingold Lee, Daniel N.

Patent number: 11116326Abstract: An endoskeleton elastomer that variably impacts the mattress firmness head-to-toe is described. The elastomer fills voids cut into the foam using contour cutting or spherical cap-shaped cutouts. The elastomer is poured as a hot liquid into the voids, and cools to a solid elastomer. The specific incarnation involves the creation of a set of parallel inclusions at the center of the mattress or a set of spherical cap-shaped cutouts that help prop up the hip area to maintain proper spinal alignment by firming the center of the mattress. The depth, width, shape, spacing, elastomer durometer, and location (both head-to-toe and depth in the mattress) may be varied to impact firmness in any desired manner. The mattress may also include a series of horizontal-oriented cutouts that are cut into various portions of the mattress layers. These cutouts may extend along the width of the mattress and may be placed at portions of the top and portions of the bottom of the mattress.Type: GrantFiled: August 13, 2018Date of Patent: September 14, 2021Assignee: Casper Sleep Inc.Inventors: Russell Jelinek, Jesse Menayan, David Holm, Jeff Chapin
