20160088438MOBILE DEVICE ASSISTED SMART BUILDING CONTROL - A system for signaling electronic devices based on the occupancy of one or more regions of a building includes a central controller with a wireless receiver to receive data indicative of the occupancy of a region of a building from fixed wireless sensors associated with the building. The central controller also receives estimated locations for one or more mobile wireless devices. The central controller can also receive an indication of the proximity of one or more mobile wireless device to a person. The central controller can determine one or more location estimates for at least one mobile wireless device. The central controller can weight some or all of the fixed wireless sensor occupancy indications and device location data based on the proximity indication and selects one or more output devices (e.g. wireless speakers or WiFi enables lights) to operate. The central controller can be located within a mobile wireless device. In this case the challenge for the controller is determining how to weight the relative importance of mobile device location and sensor data indicating person location. In several embodiments the disclosed system provides means for weighting the mobile device location, based in part on the person-to-device proximity indications in the broader task of generating occupancy estimates for one or more regions of a building and operating output devices based on occupancy estimates. For example the central controller could be located in a smartphone, thereby enabling the smartphone to play music on a dynamic subset of the wireless speakers located throughout a building, depending on the location of the user. The subset of speakers could be chosen based in part on weighting person and device location estimates, whereby the weights can be based in part on the proximity indication. When the person is close by the wireless device, device location is heavily weighted in selecting the subset of wireless speakers and when the person is determined to be non-proximal to the smartphone, occupancy indications form fixed wireless sensors receives increased weighting.03-24-2016

20150277900Dynamically building an Unstructured Information Management Architecture (UIMA) pipeline - A pipeline development environment includes a toolset that includes a visual design editor. The editor comprises a display interface having a palette of known Annotators that may be selected by a developer. The pipeline development environment also includes or has associated therewith a data repository. The data repository stores datasets. A particular dataset is associated with an Annotator and comprises dependency data generated from execution of a pipeline (or some portion thereof). The repository typically stores datasets from many pipeline runs, including runs of other pipelines, multiple runs of a given pipeline with different inputs, etc. Using the editor, a developer creates a visual representation of the pipeline. As Annotators are added into the pipeline, system tooling dynamically generates the descriptor files and other configuration parameters (for the new pipeline), preferably based on the dependency data associated with the individual Annotators and retrieved from the repository.10-01-2015
20150277901Recording, replaying and modifying an Unstructured Information Management Architecture (UIMA) pipeline - The technique herein substantially improves productivity of Annotator developers by providing methods and systems to develop and test Annotators without having to run a full pipeline every time changes are made to a particular Annotator. To this end, preferably a running pipeline is instrumented to enable automated recording of static configuration and dynamically-generated event data as the pipeline is executed. Based on these data, a reusable data model is generated that captures code and other dependencies in the pipeline (e.g., configuration parameters, intermediary CASes, program flow, annotations, and the like). The data model is then used to facilitate testing of Annotators without using the full pipeline (or even major sub-pipelines therein).10-01-2015
