SINR estimation may include receiving a Physical Layer Protocol Data Unit (PPDU) including a LLTF and extracting groups of transmission symbols from the LLTF. Next, groups of fragmented symbols may the groups of transmission symbols. One or more Sum of the Squared Magnitudes (SSM) may be determined, such as an SSM of the total signal, an SSM of the signal without ISI and/or noise, an SSM of ISI, an SSM of noise. Finally, SINR may be estimated using one or more SSMs (e.g., the SSM of noise, the SSM of signal, and the SSM of ISI).

Abstract: A bank of a memory device may be divided into column planes. Each column plane may be associated with column selects. In some examples, a portion of a column plane associated with one column select may be used to store metadata associated with data of the remaining column selects. In some examples, the metadata may be mapped to the data based on a portion of a column address. In some examples, whether the memory device provides metadata responsive to a column address may be based on a value stored in a mode register. In some examples, the portion of the column plane associated with the one column select associated with metadata may also store error correction code data associated with the data of the remaining column selects.

Abstract: Disclosed are methods and apparatuses for decoding an image. A method includes receiving a bitstream obtained by encoding the image; dividing a first coding block into a plurality of second coding blocks; generating a prediction block of a second coding block based on syntax information obtained from the bitstream; and reconstructing the second coding block based on the prediction block and a residual block of the second coding block, the residual block being obtained by performing a dequantization and an inverse-transform on quantized transform coefficients from the bitstream. The first coding block has a recursive division structure. The first coding block is divided based on at least one of a quad tree division, a binary tree division or a triple tree division.

Abstract: Data storage devices having the same capacity but with a different number of spare blocks and a different number of unusable blocks may cause device-to-device performance variance. This variance may be minimized by using illusory free blocks for relocation while using actual free blocks for other operations. In this regard, each data storage device having the same storage capacity may include a corresponding number of unusable blocks and a corresponding controller. Each controller may obtain a minimum number of blocks for supporting a predetermined storage characteristic. Each controller may calculate a respective number of spare blocks based on a respective number of unusable blocks, perform relocation for the respective data storage device based on the minimum number of blocks, and perform operations, which are not relocation, based on the minimum number of blocks and the respective number of spare blocks.

Abstract: Components of a public certificate authority (CA) generate respective cryptographic assertions during performance of respective tasks of a certificate issuance workflow and a workflow approval component approves/rejects certificate issuance, based upon verification of the cryptographic assertions. For example, a workflow manager may assign tasks of a certificate workflow process to a number of components that process the tasks. The components generate responses and sign the respective responses with keys particular to each component. The workflow manager gathers the cryptographic assertions and sends them to a workflow approval component that validates the assertions, verifies the assertions indicate successful completion of the workflow and approves or rejects certificate issuance.

Abstract: Systems and methods for resource management are disclosed. A search request may be received at a resource management service of a provider network. The search request may be received from a client device that does not have permission to access resources in a protected region of a provider network. The search request may specify a query associated with at least one operational health indicator in the protected region. It may be determined, using a secure query service, that the at least one operational health indicator does not exist in the protected region. The secure query service enables the client device to obtain information about the resources in the protected region without gaining access to the resources in the protected region. Sending of a notification indicating that the at least one operational health indicator does not exist in the protected region to the client device may be caused.

Abstract: Apparatus and methods for page-based soft post package repair are disclosed. Based on data stored in a storage element, an address may be decoded to a prime row, a row-based redundant row, or a page-based redundant row. A match logic circuit may determine whether the address corresponds to a defective prime row and generate a match signal. A decoder can select a redundant row to be accessed instead of a prime row in response to the match signal indicating that the address data corresponding to the address to be accessed matches defective address data stored in a volatile memory. A page-based redundant row allows for page-by-page substitution for defective memory, allowing functional portions of memory to continue to be used.

Abstract: A method and system are disclosed for tailoring the functionality of a monitoring system based on an identified orientation of an imaging device, typically a digital camera. The imaging device is wirelessly communicable with one or more base stations and/or access points over a WLAN. Captured media is processed depending on the identified orientation. The processed media is used to generate and display an image on a user device with one or more aspects of the display, such as aspect ratio or video compression rates, being dependent on the identified orientation. The size or shape of an activity zone that is monitored to trigger image capture and transmission may also be tailored to the identified orientation.

Abstract: Latch-based methods and apparatus for performing neural network weight parity detection on the die of a non-volatile memory (NVM) array to detect bit flip errors within neural network weight data are described, particularly for use with floating point number values. Upon detection of a parity error in a neural network weight, the erroneous weight is set to zero to trim the corresponding neuron from the network, thus preventing the erroneous value from significantly affecting the network, particularly in situations where the bit flip would otherwise affect the magnitude of a floating-point weight value. The exemplary latch-based procedures described herein are linear procedures that do not require logic decisions. Procedures are also described that assess an amount of degradation in the NVM array based on parity bit data collected in the latches. Multiple plane and multiple die NVM array implementations are also described for massive parallel processing.
