Abstract: Systems and methods provide customers with a need-based warranty using a deep learning neural network. After categorizing, a customer need is mapped to a warranty type based on the SLA needs. Warranties may then be suggested based on customer need. In another embodiment, systems and methods detect an optimal warranty based on part failure and performance of a server. A mean time to resolve or replace can be minimized in future failure instances by comparing the derived replacement time with available warranty offerings to identify potential deviations and thereby recommend an optimal warranty from the available offerings. In a further embodiment, systems and methods identify and offer additional service contracts for vender services. A warranty proposer looks for warranty types that are emitted by a warranty-types analyzer and by a technical-support analyzer. The overlapping warranty offers are provided to customers.

Abstract: An indication to perform a write operation at a memory component can be received. A voltage pulse can be applied to a destination block of the memory component to store data of the write operation, the voltage pulse being at a first voltage level associated with a programmed state. An erase operation for the destination block can be performed to change the voltage state of the memory cell from the programmed state to a second voltage state associated with an erased state. A write operation can be performed to write the data to the destination block upon changing the voltage state of the memory cell to the second voltage state.

Abstract: Systems and methods for use in mapping an interior space of a product storage facility include at least one sensor that captures distance measurement data with respect to an interior space of the product storage facility. A computing device obtains a first image representing a 2-dimensional map of the interior space of the product storage facility and processes this image to define a boundary of the interior space of the product storage facility and detect individual structures located within the interior space of the product storage facility. Then, the computing device defines separate department areas, assigns a department label to each of the separate department areas, and converts the 2-dimensional map representing the detected structures and the defined separate department areas and the department labels assigned to the separate department areas into a second image representing a 3-dimensional map of the interior space of the product storage facility.

Abstract: A radio frequency system package may include waveguides and loading blocks. The loading blocks may include dielectric material having a high dielectric constant between 13 and 20. Additionally, the loading blocks may be made of mold, epoxy, or the like material, and the loading blocks may fit into a region cut out of the waveguides. Moreover, the loading blocks may lower the cut-off frequency for wireless communication otherwise provided by the waveguides without the loading blocks (e.g., 28 GHz). In particular, the loading blocks may facilitate communication in low mmWave frequencies, such as 24 GHz.

Abstract: Systems and methods for transaction authorizations using a distributed database are disclosed. The system may allow registered transaction account holders and merchants to interact and complete transactions according to workflows enforced by smart contracts. The system may include an issuer system that receives a transaction authorization request comprising a merchant ID, a transaction account number, a transaction amount, and a transaction ID.

A transaction record is stored which indicates that the loyalty account has the transaction data for meeting the purchase requirement parameter. The transaction record is transmitted to consensus participants associated with the blockchain network.

Abstract: A processing device in a memory system maintains a counter to track a number of read operations performed on a data block of a memory device and determines that the number of read operations performed on the data block satisfies a first threshold criterion. The processing device further determines whether a number of scan operations performed on the data block satisfies a scan threshold criterion. Responsive to the number of scan operations performed on the data block satisfying the scan threshold criterion, the processing device performs a first data integrity scan to determine one or more first error rates for the data block, each of the one or more first error rates corresponding to a first set of wordlines of the data block, the first set comprising first alternating pairs of adjacent wordlines.

Abstract: A processing device in a memory system receives a first read request from a host system, wherein the first read request is directed to first data stored at a first address in a block of the memory component. The processing device determines that the first address is located within a first region of the block and increments a read counter for the block by a default amount. The processing device further receives a second read request from the host system, wherein the second read request is directed to second data stored at a second address in a block of the memory component, determines that the second address is located within a second region of the block and increments the read counter for the block by a scaled amount.

Abstract: Storage devices include a memory array comprised of a plurality of memory devices. These memory devices are programmed with a modified distribution across the available memory states within the devices. The modified distribution of memory states attempts to minimize the use of memory states that are susceptible to negative effects. These negative effects can include read and write disturbs as well as data retention errors. Often, these negative effects occur on memory states on the lower and upper states within the voltage threshold range of the memory device. The distribution of memory states can be modified though the use of a modified randomization seed configured to change the probabilities of programming of each page within the memory device. This modification of the randomization seed can yield desired distribution of memory device states that are configured to reduce exposure to negative effects thus prolonging the overall lifespan of the storage device.
