Abstract: Some embodiments provide a method that receives a specification of a neural network for execution by an integrated circuit. The integrated circuit includes a neural network inference circuit for executing the neural network to generate an output based on an input, an input processing circuit for providing the input to the neural network inference circuit, a microprocessor circuit for controlling the neural network inference circuit and the input processing circuit, and a unified memory accessible by the microprocessor circuit, the neural network inference circuit, and the input processing circuit. The method determines usage of the unified memory by the neural network inference circuit while executing the neural network. Based on the determined usage by the neural network inference circuit, the method allocates portions of the unified memory to the microprocessor circuit and input processing circuit.

Abstract: This disclosure is directed to, in part, mobile carts that are configured to determine their respective locations based on analysis of image data generated by cameras mounted to the respective carts. For instance, an example mobile cart may include at least one camera of a field-of-view directed substantially away from a cart and substantially towards an outward environment of the cart, such as toward an inventory location that houses one or more items. The mobile cart may generate image data representative of items housed at an inventory location adjacent to the cart and may use computer-vision techniques to analyze the image data and determine characteristics of these items. The mobile cart may then use this information to determine which section of multiple sections of a store in which the cart is currently located.

Abstract: Systems and methods are provided for automated modification of delivery parameters. Particularly, computing model that is trained to determine a probability that a delivery defect is likely to occur for a given delivery or set of deliveries. Based on the probability, various limitations associated with the deliveries may be activated or deactivated on a mobile device application used by a delivery driver to perform the deliveries. The systems and methods reduce the number of delivery defects that occur while simultaneously reducing the use of unnecessary guardrails for low-risk deliveries. The model may be queried in real-time such that guardrails for a delivery itinerary may be optimized prior to the delivery driver beginning the delivery route.

Abstract: Methods and apparatuses for improving network packet transmission performance in terms of latency with reduced packet retransmission times and fewer packet drops in congested networks are provided. Packet-switched networks can experience long delays while waiting for out-of-order packets or re-transmissions of lost packets. In addition, network faults such as transmission path failures can result in excessive delay while attempting to find a new route over which to transmit packets. To improve packet transmission performance, application data may be encapsulated into first network packets by a first transport protocol having an interface exposed to the application, in the first network packets may be encapsulated into second network packets according to a second transport protocol. The second transport protocol can enable the second network packets of a same packet flow to be transmitted across multiple paths over the network.

Abstract: A method for a first network device involves transmitting, to one or more second network devices, an uplink message that includes an indication of a receive window time interval, and may also include an indication of a request for a downlink message. The method also involves initiating a scheduled receive mode that causes the first network device to transition the first network device to a first power state, and perform a receive window procedure after the receive window time interval has elapsed. The receive window procedure includes transitioning the first network device to a second power state and listening for the downlink message for a duration of time. The method further involves determining that an expiration condition has been met while the first network device is in the scheduled receive mode. Additionally, the method involves terminating the scheduled receive mode upon determining that the expiration condition has been met.

Abstract: Technologies for mesh path selection are described. One method of operating a first wireless mesh device includes determining, using first client information about a first link, the first link using a first frequency range, a first metric representing airtime usage on the link, and a second metric representing a first amount of data on a second link, the second link using the first frequency range. The method determines a third metric on a third link, the third link using a second frequency range. The method determines, using the metrics, a first throughput associated with a first path with the second link and a second throughput associated with a second path. The method determines that the third link results in better throughput and sends or receives first data on the third link.

Abstract: Systems and methods for testing a biological sample for each of two or more target pathogens employ fluorescence detection from a single fluorescence reading chamber. A method of testing a biological sample for each of two or more target pathogens includes forming a detection cycle liquid by combining detection cycle compounds with a biological sample liquid formed from a biological sample. The detection cycle compounds include respective CRISPR enzymes for each of the two or more target pathogens. The respective CRISPR enzymes are tagged with respective spectrally unique fluorescent probes. The detection cycle liquid is exposed to a multi-wavelength fluorescence excitation light. A multi-wavelength fluorescence light emission detection signal indicative of intensity of fluorescence light emitted by the detection cycle liquid over multiple wavelengths is processed to generate detection data indicative of presence or absence of each of the two or more target pathogens in the biological sample.

Abstract: In various embodiments described in the present disclosure, a device identifier is generated based at least in part on a set of values corresponding to a set of fields representing information associated with a device. For example, the set of values are converted to a bitstream which is encoded using an alphabet based at least in part on an encoding schema.

Abstract: A thread of a storage server determines that a command to modify a reservation record which comprises access permissions of an object stored at the server has been received. A version of the record is stored in an in-memory cache. The thread acquires a first lock associated with the record in exclusive mode, and a second lock in shared mode. The thread reads the cached version, constructs a modified version indicated in the command, and releases the second lock without updating the cache. After entries representing the modified version are stored in an operations journal, the thread acquires the second lock in exclusive mode and updates the cache. The thread then releases both locks. An indication that the command has succeeded is provided without verifying that the second version is stored at a metadata store.

Abstract: Devices and techniques are generally described for targeting of devices. In various examples, a first natural language input comprising a first request to output a response may be received by an input device. A first component may determine first data associated with the input device. A plurality of devices associated with the first data may be determined. First state data describing a state of each device of the plurality of devices may be determined. A first device of the plurality of devices may be determined as a target device for the first request based at least in part on the first state data. The first device may be different from the input device. First instructions may be sent to the first device effective to cause the first device to display the first visual content.

Abstract: A hardware card that can be implemented in a server system is disclosed. The hardware card may be, for instance, a network interface card coupled to a board such as a motherboard or backplane in a computing system. In various instances, the hardware card reports a temperature to a management controller on the board (e.g., a baseboard management controller) that is adjusted due to thermal degradation of the hardware card. For example, the temperature output by the hardware card may be adjusted based on a comparison of a current temperature profile (including transient temperature of the hardware card) to a predetermined temperature profile stored on the hardware card.

Abstract: Methods for improving performance of tiered storage of a data processing service by detecting and reducing thrashing of data blocks between warm and cold storage tiers are disclosed. In order to understand the frequency of hits by incoming queries to data blocks that are not currently stored in the warm storage tier, the elapsed time between query hits to the respective data blocks may be tracked using timers. Times below a given amount of time may be used to indicate thrashing. For example, recently evicted data blocks that are subsequently hit by a query within a short amount of time since eviction may indicate thrashing. In scenarios in which thrashing may be occurring, a threshold corresponding to the number of times a given data block in the cold storage tier receives a query hit before being added to the warm storage tier may be turned on.

Abstract: Contents of client-initiated handshake messages of a security protocol are obtained at a handshake processing offloader configured for an application. The offloader uses a first security artifact (which is inaccessible from a front-end request processor of the application) and the contents of the handshake messages to generate a second security artifact. The second security artifact is transmitted to the front-end request processor, which uses it to perform cryptographic operations for client-server interactions of the application.

Abstract: A high precision optical tag includes gradient features at the corners. The gradient features transition from a darker pattern proximal to the corner of the tag to a lighter pattern distal to the corner. The gradient facilitates rapid and computationally efficient determination of the corners of the optical tag at high resolution, such as to a pixel-level within an image. Once the corners of the optical tag are precisely identified, a boundary of the tag may be determined. In one implementation, with the precise information about the corners and boundary of the optical tag in the image, a pose of the camera relative to the optical tag may be determined.

Abstract: A system and method for providing metered quantum entanglement-as-a-service are described. Entangled pair source nodes apply a unitary transformation to generated entangled quantum particles, such that the entangled quantum particles are transformed into a given one of a plurality of transformed states that are selected randomly or in a manner that is not readily apparent to customers. The transformed entangled quantum particles are distributed to recipients, such as customers. However, in order for the recipients to be able to use the received entangled particles to communicate shared information, such as a shared secret, the recipients require knowledge of the respective states of the entangled quantum particles resulting from the randomly selected transformations. The state information is metered out in response to receiving payment or other authorization indicating a recipient/customer has complied with terms of use of the quantum entanglement distribution service.

Abstract: A system and method for providing quantum entanglement using a hybrid space-fiber quantum network are described. The hybrid space-fiber quantum network includes a communications hub located proximate to an optical ground station and also includes an aerial entangled particle source, such as an entangled photon source attached to a satellite, drone, aircraft, etc. An atmospheric or free-space channel is used to distribute quantum entanglement between optical ground stations that are separated by geographic distances, via the aerial entangled particle source. Also, fiber optic links are connected to the communications hub located proximate to the optical ground station. The communications hub includes optical switches that enable any of the fiber optic links connected to the communications hub to receive or send distributed quantum entanglement to a remotely located recipient endpoint via the atmospheric or free-space channel.
