Abstract: Systems and methods for determining location using magnetic fields from AC power lines are provided. As an example, each magnetic field reading collected by the device over time can be analyzed to determine a plurality of characteristics of the magnetic field. One or more of the plurality of characteristics can describe a component of the magnetic field that oscillates at a frequency associated with the AC power lines. The plurality of characteristics can be compared to expected values respectively associated with a plurality of locations and provided by a map of the magnetic field to determine a location at which each magnetic field reading was collected. In further embodiments, magnetic field readings collected by the device over time can be analyzed in conjunction with other data or constraints to determine a trajectory of the device. In addition, the map can be updated using the collected readings and the determined trajectory.

Abstract: Mesh node modules are associated with competitors in an arena to relay through a mesh network formed by the modules competitor biometric and/or parameter information.

Abstract: A system for distributing media includes a wide area network (WAN), a media player coupled to the WAN at a first home, and a media server coupled to the WAN at a second home for providing media. A service is coupled to the WAN for receiving a request for media from the media player and for establishing a connection between the first and second homes over the WAN. Media is streamed across the WAN from the second home to the first home. The system may include a storage device coupled to the media player where media is transferred across the WAN for storage at the storage device. A media device may be coupled to the media player for playing the streamed/transferred media where the media player and the media device may comprise a television, stereo, or computer and the media item may comprise video, photographs, or audio.

Abstract: Described is a method and system for producing a three-dimensional (3D) structure using 3D printing. A 3D structure, having multiple regions, is produced using a 3D printer having at least one extruder formed to receive a printer filament. The printer filament has at least one type of material having radio frequency (RF) absorption properties. The RF absorption properties are varied at different regions of the 3D structure by varying the extrusion of the at least one type of material at different regions of the 3D structure.

Abstract: Devices and methods for enhancing the operations of fluid systems are provided. For example, this document provides pressure differential relief valves that are well suited for use with medical fluid reservoirs. The pressure differential relief valves provided herein are described in the context of a medical fluid system, such as an extracorporeal blood flow circuit, but the devices and methods provided herein can be implemented in other types of fluid systems including, but not limited to, pneumatic systems, hydraulic systems, fluid power systems, petroleum systems, and various other types of gaseous or liquid-based fluid systems.

Abstract: Mesh node modules are associated with vehicles and companion nodes can dynamically form a mesh network which uploads location information of the nodes and in some cases additional information, e.g., road condition or proximity to objects.

Abstract: Mesh node modules are associated with pieces of luggage, or packages, etc. and companion luggage or packages can dynamically form a mesh network which uploads location information of the nodes and in some cases additional information, e.g., shock signals, to a network. The information may be downloaded to an owner's CE device.

Abstract: In an audio speaker network, the individual speakers of the network have lamps on them that are controlled to present a light show in synchrony with the audio being played by the system.

Abstract: A speaker system comprised of more than one speaker, which utilizes the known characteristics and location of each speaker to enhance low frequency (low (bass) frequency) performance of the system.

Abstract: A networked-speaker system which includes noise cancelling for active suppression of unwanted sounds. Feed-forward or feed-back cancelation can be used as appropriate for the location of the microphone sensing the noise.

Abstract: In a multi-speaker audio system for, e.g., a home entertainment system or other entertainment system, each networked-speaker (wired or wireless) is activated or deactivated as appropriate such that audio play follows a user as the user moves around the home.

Abstract: In an audio speaker network, setup of speaker location, sound track or channel assignation, and speaker parameters is facilitated by an application detecting speaker locations and prompting a user to input rough room boundaries and a desired listener location in the room. Based on this, optimum speaker locations/frequency assignations/speaker parameters may be determined and output.

Abstract: A high efficiency energy conversion system disclosed herein incorporates a piston assembly including a sealed cylinder for storing a working fluid and an energy conversion element attached to the piston assembly. A kinematic mechanism such as a cam lobe or a scotch yoke may be used as the energy conversion element. In one implementation, the kinematic mechanism may be configured to provide rapid piston expansion in a manner so as not to allow the expanding working fluid inside the piston to achieve thermodynamic equilibrium. In an alternate implementation, the kinematic mechanism is further adapted to generate a compression stroke in a manner to provide the working fluid inside the piston to achieve thermodynamic equilibrium conditions throughout the compression stroke.

Abstract: A method and apparatus for generating a profile page. A computer system identifies a group of potential profiles images from an image. The computer system identifies a group of features in the image. The computer system generates the profile page based on a potential profile image selected from the group of potential profile images and the group of features in the image. The computer system displays the profile page on a display system, enabling generating the profile page.

Abstract: A method for visually accessing information. A computer system displays pie charts in a graphical user interface in a display system. The pie charts have sections that represent pieces of the information, and each of the pie charts represents a type of the information. The computer system receives a user input selecting a portion of the sections from the pie charts displayed in the graphical user interface. The computer system displays a new pie chart in the graphical user interface using the portion of the sections selected by the user input. The new pie chart has new sections representing selected pieces of the information corresponding to the portion of the sections. The new sections have sizes based on a policy, and the sizes for the new sections indicates relative values of the pieces of the information with respect to each other. The new pie chart enables visually accessing the information.

Abstract: A method and apparatus for facilitating networking in a social network. A computer system identifies a group of features in an image for a person in the social network. The computer system also identifies a characteristic for networking from the group of features. Further, the computer system identifies a set of people in the social network having the characteristic. The computer system also performs an action enabling networking in the social network with respect to the person and the set of people in the social network having the characteristic.
