Autonomous event generator
Computerized devices search each of a group of different calendars of a group of attendees of a proposed event for an available timeslot within each of the calendars that meets boundary conditions specified for the proposed event. In response to failing to find an available time slot in common to all attendee calendars that meets the boundary conditions, the devices autonomously identify a common existing event scheduled within the calendars of the attendees that can accommodate the boundary conditions and add the new event to the existing event, or reschedule a previously scheduled event of one or more of the attendees to create a common, free timeslot for the new event where the event cannot be accommodated within an existing event. |

System and method for tracking objects within a facility
Objects in a facility, such as users or totes, may be tracked as the object moves within the facility. An object representation of the object may be detected using image data. Apparent motion of the object representation may also be detected based on changes within the image data over time, which can help determine movement data for the object representation. However, the identity of the object representation may not be known. Using data from motion sensors in a device, movement data for the device can be generated. Thereafter, the movement data determined using the image data and the movement data determined using the data from the motion sensors in the device are compared for a possible match. If a match is found, an identifier of the device may then be associated with the object representation in the image data for tracking purposes. |

Non-disruptive referencing of special purpose operators for database management systems
Approaches herein transparently delegate data access from a relational database management system (RDBMS) onto an offload engine (OE). The RDBMS receives a database statement referencing a user defined function (UDF). In an execution plan, the RDBMS replaces the UDF reference with an invocation of a relational operator in the OE. Execution invokes the relational operator in the OE to obtain a result based on data in the OE. Thus, the UDF is bound to the OE, and almost all of the RDBMS avoids specially handling the UDF. The UDF may be a table function that offloads a relational table for processing. User defined objects such as functions and types provide metadata about the table. Multiple tables can be offloaded and processed together, such that some or all offloaded tables are not materialized in the RDBMS. Offloaded tables may participate in standard relational algebra such as in a database statement. |

Providing matching security between data stores in a database system
Methods, systems, and devices for providing matching security between data stores are described. In a database system, an operational data store may store transactional datasets and an analytical data store may store analytics datasets generated based on the transactional datasets.

System and method for spectral filtering of optical signals
A method for spectral filtering an input optical signal is described. The filtering system uses Brillouin gain inside an interferometer. The interferometer is biased to null signals that propagate without Brillouin gain, but due to asymmetric levels of gain in the interferometer arms the interference null is disturbed for signals of an optical frequency that experience Brillouin gain. The filter thereby preferentially passes signal frequencies that are inside the Brillouin gain bandwidth creating a high extinction ratio filter. The narrow bandwidth of the Brillouin gain effect can allow for spectrally narrow filters such as 30 MHz. The filter can be realized in a stable Sagnac loop configuration even if the pump and signal are combined prior to the Sagnac loop by using a power control device such as an attenuator placed asymmetrically inside the loop. The filter can achieve net gain and can be designed to have a tunable bandwidth. |
