Abstract: A cooler with a hinging lid is comprised of a top deck having an opening and a unitary hinging lid to cover the opening; insulated sidewalls; and a bottom that together define an enclosed insulated inner volume for storage of objects. The inner volume can be accessed by opening the hinging lid. The hinging lid can be selectively opened, segment by segment, to access the inner volume while minimizing the exchange of air between the inner volume and the air surrounding the cooler. The hinging lid is comprised of a pull flap tab, an interior layer of reflective insulating material, at least one layer of support insulation material and a waterproof outer surface layer. The support insulation material of the hinging lid is divided into at least two discrete segments comprising a first segment and a second segment and can be articulated as a hinge between the segments.

Abstract: A method for identifying log likelihood ratio (LLR) values includes programming codewords into nonvolatile memory devices in response to receiving host-requested write instructions and performing background reads of the programmed codewords in a block at a default threshold voltage, at one or more threshold voltage offset that is less than the default threshold voltage and at one or more threshold voltage offset that is greater than the default threshold voltage. One of the background reads is decoded to identify the stored codeword(s) and a set of LLR values is identified using the stored read results and the identified codeword(s). The process of performing background reads, storing, decoding and identifying is repeated to identify a set of LLR values for each block and further to identify updated sets of LLR values. Host-requested reads are performed and are decoded using LLR values from the updated set of LLR values corresponding to the block that was read.

Abstract: A nonvolatile memory system, a nonvolatile memory controller and a method for reducing latency of a memory controller are disclosed. The nonvolatile memory system includes a read circuit that performs background reads of an indicator page of each block to identify outlier blocks. A background reference positioning circuit performs background reads of representative pages of the outlier block at threshold voltage offsets to identify sets of updated threshold voltage offset values. Upon endurance events, retention timer events and read disturb events at a closed block background reads are performed of representative pages of the closed block at threshold voltage offsets to identify sets of updated threshold voltage offset values.

Abstract: A transparent clock converter is interposed between a non-precision time protocol (non-PTP) enabled network node and other portions of the network. The transparent clock converter effectively converts the non-PTP node into a transparent clock node. In some embodiments the transparent clock converter includes physical layer devices, but not media access controllers.

Abstract: A nonvolatile memory system, a nonvolatile memory controller and a method for reducing latency of a memory controller are disclosed. Upon the occurrence of one or more of an endurance event, a retention timer event and a read disturb event at a closed block, a background reference positioning circuit performs background reads of representative pages of each page group of a closed block at offsets to each threshold voltage that is required for reading the representative pages of each page group of the closed block to identify a set of updated threshold voltage offset values for each page group of the closed block. When a usage characteristic is determined to meet a usage characteristic threshold, a read circuit performs subsequent host-requested reads using a threshold voltage shift read instruction and reads of pages of the closed block are performed using the set of updated threshold voltage offset values corresponding to the page group of the page being read.

Abstract: A nonvolatile memory controller and a method for erase suspend management are disclosed. The nonvolatile memory controller includes an erase suspend circuit configured for determining a pre-suspend time each time that an erase operation of the nonvolatile memory device is suspended and for determining whether an erase-suspend limit has been reached using the determined pre-suspend time. The erase suspend circuit is further configured for incrementing the number of program and erase cycles when the erase-suspend limit has been reached.

Abstract: This invention provides a backpack with a compartment containing a plurality of pockets for carrying personal electronic devices, including a specific pocket for storing a rechargeable battery pack within a range of sizes, shapes and cable socket number/placement on the pack's housing. The battery pocket defines crossing bands of elastic that accommodates/secures various battery form factors. Power cable access to sockets on the pack is eased by the flexibility of the straps and their interstices. The main compartment includes pockets for other electronic items, such as a tablet computer, smartphone and/or music player. Pockets are constructed from a mesh that includes an elastomer coating for frictional retention of items. A cable pocket, including pass through openings is also provided to route and store gathered/wound sections of power cables from the battery pack located therebelow. Cables extend from the cable pocket to various electronic devices in adjacent pockets, or externally.
