20100124376 | Determination Of Class, Attributes, And Identity Of An Occupant - Disclosed herein is a method and system for determining class, attributes, and identity of an occupant in an occupancy space. An infra-red image of the occupant in the occupancy space is captured. The infra-red image information of the captured image is digitized to obtain a thermal signature of the occupant. The thermal signature of the occupant is compared with thermal signatures, characteristics, and attributes common to a class of occupants stored in a thermal signature database to determine the class, the attributes, and the identity of the occupant. The determination of the class and the attributes may, for example, comprise distinguishing between an animate occupant and an inanimate occupant, analyzing gait of the animate occupant for distinguishing between human motion and non-human motion, and enumerating occupants in the occupancy space using an edge detection algorithm. | 05-20-2010 |
20100235004 | Predictive Conditioning In Occupancy Zones - A method and system for predictively controlling environmental conditions of multiple occupancy zones in an occupancy space are provided. Occupancy and environmental conditions of each of the occupancy zones are detected and identified. The detected occupancy is stored in an occupancy database. Patterns of occupancy of each of the occupancy zones are determined using the occupancy database. Future occupancy of the occupancy zones is predicted based on the occupancy patterns of the occupancy zones. The environmental conditions of the occupancy zones are controlled based on the detected occupancy and/or the predicted future occupancy. The environmental conditions of the occupancy zones in the occupancy space are thereby predictively controlled by simultaneously incorporating an occupant's desired settings, existing and historical temperature data within the occupancy space, and weather data. The predicted occupancy can be combined with demand response signal and energy tier rates to make optimal conditioning decisions. | 09-16-2010 |

20140258225 | SYSTEMS AND METHODS FOR HOST DETECTION OF USB ASYNCHRONOUS NOTIFICATION CAPABILITY - Systems and methods for detecting legacy storage devices that may falsely and/or incorrectly report to host systems that they have removable media. Such false or incorrect reporting may cause the host system to periodically poll the storage device as to whether the device is ready for I/O processing. Such polling would be unnecessary and represent a waste of power expended by the host system. In one embodiment, the present system may implement processes that periodically poll storage media and update a database. The database would be a listing of storage devices indicating whether they truly have removable media or falsely report that they have removable media. In another embodiment, the present system may apply some heuristically testing to determine whether a storage device so falsely indicates removable media. In another embodiment, telemetry service may be used by a group of hosts to share data regarding such storage devices. | 09-11-2014 |
