Abstract: A composite closure which includes an improved sealing gasket material and shape. The Closure includes an end panel that is received in a circular plastic fitment having a central opening therein defined by an inwardly extending flange which over-lies in an outer periphery of the end panel and an integral skirt downwardly depending from the flange. The fitment includes an inwardly extending circumferential bead or bead segments which include a substantially non-deformable flat vertical surfaces that are substantially parallel to the axis of the closure and axially positioned to contact the radial outer-most edge of the end panel when the closure is fully applied to a container. The sealing gasket has the shape of an annulus with a particular cross-section and formed from a PVC free material.

Abstract: Methods, systems, and devices for unmap backlog in a memory system are described. A memory system may be configured to support receiving an unmap command from a host system and signaling, to the host system, an indication that the unmap command has been processed (e.g., handled, acknowledged). In response to the unmap command, the memory system may proceed with various unmap operations, which may include unmapping at least some of the associated addresses after indicating that the unmap command has been processed. For example, a memory system may implement an unmap backlog table to identify sections of addresses that are to be unmapped (e.g., after indicating that the unmap command has been processed). In some examples, the memory system may support various aspects of prioritization between unmap operations (e.g., background unmap operations) and other access operations such as read operations, write operations, or other access operations.

Abstract: The present invention discloses a method for preparing a full-body marble-patterned glass mosaic, comprising mixing a glass powder with an additive to obtain a mixture; adding water to the mixture and mixing thoroughly; granulating and sieving to obtain base clay body powder; mixing a colorant and a flux according to a specific ratio to obtain a colorant mixture in powder form; distributing the base clay body powder and the colorant mixture into multiple layers via a mold; press-molding to obtain a clay body; firing the clay body to obtain the full-body marble-patterned glass mosaic. Accordingly, the present invention provides a full-body marble-patterned glass mosaic prepared by the method described above. The glass mosaic of the present invention has a strong layering texture and a well-defined structure, and it faithfully resembles the pattern and texture of natural marble.

Abstract: Devices and techniques for data removal marking in a memory device are described herein. A delete command can be received at the memory device. A count of data portions in the delete command can be compared to determine whether the count is below a threshold. In response to determining that the count of data portions is below the threshold, the data portions can be written to a buffer. When a buffer full event is detected, a segment of an L2P data structure can be loaded into working memory of the memory device. Then, each record in the segment of the L2P data structure that has a corresponding entry in the buffer can be updated to mark the data as removable (e.g., invalid).
