Abrégé

This document describes textile assemblies for speakers, including textile assemblies with inlaid tensioning yarns, and associated apparatuses and methods. The textile assembly includes a textile body (106) with inlaid tensioning yarns (302, 304). The textile assembly (102) may be a fully-fashioned textile swatch. The tensioning yarns are inlaid at intervals in the textile body but can slide within or be pulled through the textile body. Further, the tensioning yarns have ends (306, 308, 402, 404) that are accessible near the edges of the textile body for various reasons. First, pulling on them while the textile assembly is on an acoustic device (104) tensions the tensioning yarns such that they limit movement of the textile assembly and break up vibration modes. Second, their ends can be tied directly to, formed into loops to hook over, or wound around, features (208) on the acoustic device to removably secure the textile assembly to the acoustic device.

. . ABSTRACT OF THE DISCLOSURE A process for optimal query scheduling includes receiving in an information retrieval data processing system, a request to accelerate query execution of a specified query to a time prior to a scheduled time. A specific field corresponding to data in a database is then identified in the query and a freshness of data requirement for the specific field retrieved along with a frequency of change of the data corresponding to the specific field. Then, if execution of the specific query at the time prior to the scheduled time instead of the scheduled time is determined not to violate the freshness of data requirement based upon the frequency of change of the data corresponding of the specific field, the specific query is scheduled for execution at the time prior to the scheduled time. But otherwise, the scheduled time may be maintained for executing the specific query. CA 3069090 2020-01-21

Abrégé

The technology provides for live migration from a first cluster to a second cluster. For instance, when requests to one or more cluster control planes are received, a predetermined fraction of the received requests may be allocated to a control plane of the second cluster, while a remaining fraction of the received requests may be allocated to a control plane of the first cluster. The predetermined fraction of requests are handled using the control plane of the second cluster. While handling the predetermined fraction of requests, it is detected whether there are failures in the second cluster. Based on not detecting failures in the second cluster, the predetermined fraction of requests allocated to the control plane of the second cluster may be increased in predetermined stages until all requests are allocated to the control plane of the second cluster.

Abrégé

A method of computing a join pattern agnostic aggregate function includes loading source code and parsing the source code to identify different database query operations. In response to the identification of an aggregate function in one of the different database query operations in which records in multiple tables are joined together in a table join, a multiplicity of primary keys are retrieved, each corresponding to a different one of the multiple tables and also an object of one of the tables referenced by the identified aggregate function. An existence of a fan out condition associated with the table join is then computed. On condition that an existence of the fan out condition is not computed a non-fan out sensitive implementation of the aggregate function is invoked with respect to the object. But, otherwise, a different, fan out sensitive implementation of the aggregate function is invoked with respect to the object.

Abrégé

Securing at rest data on a cloud hosted server includes, for each cloud hosted instance of a computer program, creating a key encrypted key (KEK) using a unique customer master key (CMK) corresponding to the instance, but only an encrypted form of the KEK is persisted in a database for the corresponding instance whereas the unencrypted KEK is retained in memory of the encryption process only. Thereafter, in response to a request to persist data by a corresponding instance of the computer program, a data key (DK) is randomly generated and encrypted with the KEK in memory for the corresponding instance. The data itself also is encrypted with the DK and an envelope with the encrypted DK and the encrypted data returned to the requestor, thus ensuring that the data and the encryption keys are never moved or persisted in an unencrypted form.

Abrégé

Aspects of the technology evaluate whether a response to a client device search query results in the client device traveling to a location associated with the response (Fig. 1). One or more wireless stations are selected based on the location associated with the search query (604, 606). Wireless station identifiers are sent, along with the search results, to the client device (504, 610). The client device compares the received identifiers against the identifiers of one or more observed wireless stations with which the mobile device is in communication or are otherwise visible (508). Log information is generated by the client device as a result of the comparison (510). The log information is transmitted to the network without user ID or other client-identifiable information included in the log (512). The received log information is then used to accurately evaluate conversions and evaluate search quality, which enhances the user experience and provides for a more efficient search result process (612, 614).
