Abstract: Described are systems, methods, and apparatus that enable power management and reduction at both the individual and group level to help reduce the overall power demand on a power system. One or more sensors may be positioned at different locations that collect and provide various sensor data to a remote computing system, referred to herein as a management system. The management system maintains location profiles for each location, user profiles for users at the various locations, and may also receive third party data, such as weather patterns, power system load, etc. The management system utilizes the received data to determine one or more energy saving actions that may be performed at the location(s) to reduce energy consumption and lower the demand on the power system.

Abstract: Described implementations utilize existing power lines at a location to detect and monitor the presence, position, and/or identity of users at the location. Rather than requiring dedicated monitors within each room or position within the location, the described implementations monitor a baseline voltage signal and/or an introduced voltage signal on the ground line of an existing power line of the location to determine the presence, position, and/or identity of a user at the location, either alone or in combination with other information.

Abstract: The recording of broadcast media can be performed by a network storage service even where a client is unable to provide a full copy of the media file. For example, a client might want to record a television broadcast by transmitting the content to a remote storage service. For a high definition format, however, the upload limitations of the data connection may prevent the full content from being uploaded from that client. Accordingly, clients recording the same content and using the same service can upload respective segments of the content, with each segment being provided by at least one of the clients and available for subsequent download. At least some of those clients can also store some of the segments such that those clients can act as peer sources for obtaining those segments.

Abstract: A system for distributing data to a user's device leveraging locally shared cache and multiple communication pathways. A content server of the system may pre-cache content in the shared cache in anticipation that a user will want to access the content. Among other things, pre-caching enables a user to access content on-demand that would require a faster connection to the Internet than the user may have. The system can leverage different communications pathways to the various devices utilizing the shared cache, providing timely delivery of content even if each device's individual connection to the internet is too slow to support timely delivery.

Abstract: Systems and approaches are provided for robustly detecting and tracking a user. Image data can be captured and processed to provide an estimated position and/or orientation of the user. Other sensor data, such as from an accelerometer and/or gyroscope, can be determined for a more robust estimation of the user's position and/or orientation. Multiple user detection processes and/or motion estimation approaches and their corresponding confidence levels can also be combined to determine a final estimated position and orientation of the user. The multiple user pose estimations and/or motion estimations can be combined via an approach such as probabilistic system modeling and maximum likelihood estimation.

Abstract: Ancillary or secondary displays usable with various electronic devices are described herein. In some implementations, the ancillary display may include a dual hinge to allow the ancillary display to act as a cover for a portion of an associated electronic device. In some implementations, the ancillary display may include a magnetic connector capable of providing a mechanical coupling with an electronic device. The magnetic connector may also provide a pathway for the transmission of data and/or power between the ancillary display and the electronic device.

Abstract: The invention provides a method and software for the adjustment of properties of media streams and events, principally timing information, based on a template, i.e., a groove map. The invention further provides methods by which the templates can be created, edited, and arranged within the context of the media they influence.
