Abstract: Systems and methods for backing up data are provided. Data objects or blocks of data can be encrypted with individualized keys. The keys are generated from the unencrypted data objects or blocks. The encrypted data objects or blocks and fingerprints of the encrypted data objects or blocks can be uploaded to a datacenter. Even though the data objects or blocks are encrypted, deduplication can be performed by the datacenter or before the data object is uploaded to the datacenter. In addition, access can be controlled by encrypting the key used to encrypt the data object with access keys to generate one or more access codes. The key to decrypt the encrypted data object is obtained by decrypting the access code.

Abstract: The present disclosure relates to an image registration method and a model training method thereof. The image registration method comprises obtaining a reference image and a floating image to be registered, performing image preprocessing on the reference image and the floating image, performing non-rigid registration on the preprocessed reference image and floating image to obtain a registration result image, and outputting the registration result image. The image preprocessing comprises performing, on the reference image and the floating image, coarse-to-fine rigid registration based on iterative closest point registration and mutual information registration. The non-rigid registration uses a combination of a correlation coefficient and a mean squared error between the reference image and the registration result image as a loss function.

Abstract: Computerized systems and methods are provided for automatically generating an application overflow tool that is dynamically updated and arranged to provide improved access to popular or recently used applications. These systems and methods improve existing technologies by generating an overflow panel different from a task bar, such that the overflow panel provides access to most recently used applications that are not on the task bar. As such, ease of access to applications is improved to increase user efficiency. These systems also improve the way computers operate by leveraging existing GUI layouts to reduce computing resource consumption, such as memory, network latency, I/O, and the like, that would otherwise be required improve access to applications.

Abstract: The technology relates to an exterior sensor system for a vehicle configured to operate in an autonomous driving mode. The technology includes a close-in sensing (CIS) camera system to address blind spots around the vehicle. The CIS system is used to detect objects within a few meters of the vehicle. Based on object classification, the system is able to make real-time driving decisions. Classification is enhanced by employing cameras in conjunction with lidar sensors. The specific arrangement of multiple sensors in a single sensor housing is also important to object detection and classification. Thus, the positioning of the sensors and support components are selected to avoid occlusion and to otherwise prevent interference between the various sensor housing elements.

Abstract: A method for signing data such as software images is provided that uses modules executable by a generic client to sign hashes of the software images rather than the images themselves. The method avoids both the requirement for new or updated client software and the uploading of full software images to the signing system. This approach uses a generic client that requests and downloads processing modules from the signing system to perform the pre-processing operations in signing software images, as well as optionally for post-processing operations.

Abstract: A light stake for holding a light bulb includes a spike with a body extending along a spike axis between a top end and an insertion end, a connecting base at the top end of the body, and a socket having a socket axis. The socket has a socket base, a plurality of fingers, and a strengthening fillet. The socket base is perpendicular to the socket axis and with a solid-material periphery extending on all sides of the socket axis. The fingers extend from the socket base along the socket axis, with each finger extending between a fixed end near the socket base and a movable end. The strengthening fillet is at the intersection between the fixed end of each finger and the socket base, and increases the local thickness of each fixed end and of the socket base for increased rigidity of the fixed end.

Abstract: A foil system is used with a towed marine cable array to provide downward, upward or lateral lift to the array. The foil system can be coupled with the cable and configured to bias the submerged payload toward a target position. The foil system can include a group of foil sections each having a leading edge collectively defining an angle of attack, and a group of through-cables supporting the group of foil sections within the foil system. A subset of through-cables of the group of through-cables are arranged through front halves of the group of foil sections. This subset of through-cables can be selectively tensionable, and manipulatable to define a tensioned one of the subset of through-cables as being offset from a chord that is defined between the leading edge and a trailing edge of any of the foil sections. The foil system can thus induce one or more angles of attack for the group of foil sections, based on a rotational constraint defined by the tensioned one of the through-cables.

Abstract: A method for generating a prosodic representation includes receiving a text utterance having one or more words. Each word has at least one syllable having at least one phoneme. The method also includes generating, using a Bidirectional Encoder Representations from Transformers (BERT) model, a sequence of wordpiece embeddings and selecting an utterance embedding for the text utterance, the utterance embedding representing an intended prosody. Each wordpiece embedding is associated with one of the one or more words of the text utterance. For each syllable, using the selected utterance embedding and a prosody model that incorporates the BERT model, the method also includes generating a corresponding prosodic syllable embedding for the syllable based on the wordpiece embedding associated with the word that includes the syllable and predicting a duration of the syllable by encoding linguistic features of each phoneme of the syllable with the corresponding prosodic syllable embedding for the syllable.
