Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium for retrieving information from a server. Methods can include a server receiving a set of client-encrypted queries. The server identifies a set of server-encrypted decryption keys and transmits the set to the client device. The server receives a set of client-server-encrypted decryption keys that includes the set of server-encrypted decryption keys encrypted by the client device. The server also receives a set of client-encrypted/client-derived decryption keys that were derived by the client device. The server generates matching a map that specifies matches between the set of client-server-encrypted decryption keys and the set of client-encrypted/client-derived decryption keys. The server filters the set of client-encrypted queries using the map to create a set of filtered client-encrypted queries and generates a set of query results.

Abstract: Systems and methods for the meta-estimation of data structures representing identifiers are disclosed. The system maintain one or more data records comprising one or more identifiers and one or more attributes. Using the data records, the system can generate a first data structure, such as a probabilistic data structure, that represents the plurality of data records. The first data structure can have a plurality of registers. The system can identify a subset of the plurality of registers that are equal to a predetermined value, and generate a second data structure that represents the subset of the plurality of registers. The system can then store the second data structure as a meta-estimation of the first, and can utilize the second data structure in further processing operations.

Abstract: Encrypted information retrieval can include generating a database that is partitioned into shards each having a shard identifier, and database entries in each shard that are partitioned into buckets having a bucket identifier. A batch of client-encrypted queries are received. The batch of client-encrypted queries are processed using a set of server-encrypted data stored in a database. The processing includes grouping the client-encrypted queries according to shard identifiers of the client-encrypted queries, executing multiple queries in the group of client-encrypted queries for the shard together in a batch execution process, and generating multiple server-encrypted results to the multiple queries in the group of client-encrypted queries. The multiple server-encrypted results for each shard are transmitted to the client device.

Abstract: Certain aspects of the present disclosure provide techniques for electric vehicle charging management. In one example, a method includes: building a graph representing an electrical topology of the electric vehicle charging facility and producing an updated graph by updating a state of the one or more network nodes based on electric current or power flow through the one or more passive electric components and updating a state of the one or more component nodes based on electric current or power produced or consumed by the one or more active electric components. The method further includes receiving a selected control strategy for the electric vehicle charging facility and adjusting an electric current or a power draw of an electric vehicle charging station in the electric vehicle charging facility based on the updated graph and the selected control strategy.

Abstract: Examples of the present disclosure describe systems and methods for state-based entity behavior analysis. In an example, entities of a computing environment may be represented using a hierarchical entity web. In some examples, an entity may have a state associated with it, which may be modeled using a place/transition (PT) network. Events within the computing environment may be evaluated by transitions of a PT network to determine whether an entity should change state. If an entity transitions from one state to another, one or more actions may be performed, including, but not limited to, taking a remedial action, generating a recommendation, and updating the state of one or more associated entities. Thus, aspects disclosed herein may provide a high-level overview of the state of entities of a computing environment, but may also be used to view in-depth information of entities at lower levels of the hierarchical entity web.

Abstract: Methods and wearable devices for optimizing power consumption using sensor-based position and use determinations are described here. One example method is performed at a device that includes a first sensor configured to operate with a first power consumption rate and a second sensor configured to operate with a second power consumption rate. The method includes, while a component associated with the second sensor is in an inactive state, receiving first sensor data, and determining whether the first sensor data indicates movement of the device. The method also includes, when movement of the device is indicated, operating the second sensor in an active state. The method further includes, after activating the second sensor, when second sensor data from the second sensor indicates that the device has been placed on a user’s body, continuing to operate the second sensor in the active state.
