Abstract: A Building Management System (BMS) may be controlled in accordance with predicted occupancy using a trained model. A model is trained by providing the model with time stamped environmental data and corresponding time stamped occupancy data pertaining to a training building, wherein the time stamped environmental data is derived from one or more environmental sensors of the training building and the corresponding time stamped occupancy data is derived from one or more occupancy sensors of the training building. Once trained, the trained model is provided with time stamped environmental data for a use building that is derived from one or more environmental sensors of the use building. Occupancy data for the use building is not required. The trained model outputs a predicted occupancy value that represents a predicted occupancy count in the use building, and the BMS of the use building is controlled based at least in part on the predicted occupancy value.

Abstract: Appropriate ventilation for a building space while maintaining building comfort includes tracking one or more interior environmental conditions within the building space and one or more exterior environmental conditions outside of the building space during operation of the HVAC system. An environmental model for the building space is learned over time based at least in part on these tracked environmental conditions, where the environmental model predicts an environmental state of the building space in response to operation of the HVAC system under various interior and exterior environmental conditions. A maximum allowed ventilation rate that can be achieved without causing the HVAC system to compromise on any of one or more comfort conditions of the building space is predicted using the environmental model. The outdoor air ventilation damper of the HVAC system is then controlled to provide an appropriate ventilation up to or at the predicted maximum allowed ventilation rate.

Abstract: A computer system provides a method for analyzing various parameters, variables and/or conditions associated with the operation of HVAC systems. Some example computer systems display a coordinate system with multiple graphs of variables and conditions having disparate units of measure, such as degrees Centigrade, percent, ppm, on/off, etc. In some examples, variables and conditions with similar units of measure are grouped together. The groups of similar units are plotted along different segments of the coordinate system's y-axis. The segments and their respective graphs of similar units are distributed vertically, one above the other. All of the graphs, however, share a common x-axis, which is labeled in units of time. This makes it easier to visually compare multiple, disparate variables and conditions at particular points in time. When an HVAC related problem occurs, the visual comparisons can help identify the problem and its source.

Abstract: Devices, methods, and systems for controlling a plurality of devices and equipment installed at a building. A system or common model of the devices and equipment at the building may be accessible by a technician during setup of a BMS for a building. The system model may enforce standardized device names and standardized point names that may be hardware agnostic for the plurality of devices and equipment installed at the building. A gateway in communication with the installed devices and equipment, along with a computing device storing the system model, may receive point information from the installed devices and equipment and convert the received point information into hardware agnostic point information. The gateway may receive hardware agnostic control commands from the system model and convert the hardware agnostic control commands into hardware specific control commands.

Abstract: Systems and methods are disclosed herein for identifying a category of a search term and providing search results subject to the identified category. These systems and methods may be performed by a media guidance application. The media guidance application may receive a search term that may correspond to different categories of items, and the media guidance application may identify a category that the search term is most likely related to using a hierarchical structure. The media guidance application may limit the search to the identified category of items.

Abstract: Systems and methods are described herein that maintain a context in a conversational search systems. An artificial neural network accepts current and previous queries as input and outputs a value indicating whether the previous query and the current query should undergo a merge operation or a replacement operation to maintain an intent of the user. To perform a merge operation, the previous query and the current query are combined to form a search query. To perform a replace operation, a portion of the previous query is replaced with a portion of the current query.

Abstract: Systems and methods are provided for playing a summary of a scene related to a current scene from a media asset being played in a display. This may be accomplished by a media guidance application receiving a command to play a summary of a scene related to the current playback. The media guidance application then determines a scene or scenes related to the current scene and compiles a summary of the related scenes. The media guidance application may also compile summarized content of the current scene to catch a viewer watching summary up to the current scene when the summary is complete. The media guidance application generates for display, on a second display, the summary content.

Abstract: An improved error control coding scheme is implemented in low bit rate coders in order to improve their performance in the presence of transmission errors typical of the digital cellular channel. The error control coding scheme exploits the nonlinear block codes (NBCs) for purposes of tailoring those codes to a fading channel in order to provide superior error protection to the compressed half rate speech data. For a half rate speech codec assumed to have a frame size of 40 ms, the speech encoder puts out a fixed number of bits per 40 ms. These bits are divided into three distinct classes, referred to as Class 1, Class 2 and Class 3 bits. A subset of the Class 1 bits are further protected by a CRC for error detection purposes. The Class 1 bits and the CRC bits are encoded by a rate 1/2 Nordstrom Robinson code with codeword length of 16. The Class 2 bits are encoded by a punctured version of the Nordstrom Robinson code. It has an effective rate of 8/14 with a codeword length 14.

Abstract: The perception of speech processed by a CELP based coder, such as a VSELP coder, when operating in noisy background conditions is improved by removing swirl artifacts during silence periods. This is done by removing the low frequency components of the input signal when no speech is detected. A speech activity detector distinguishes between a periodic signal, like speech, and a non-periodic signal, like noise by using most of the VSELP coder internal parameters to determine the speech or non-speech conditions. To prevent the VSELP coder from determining pitches for non-periodic signals, a high pass filter is applied to the input signal to remove the pitch information for which the VSELP coder searches.
