A multi-source peer content distribution system transfers content files from multiple, distributed peer computers to any requesting computer. The content distribution network coordinates file transfers through a mediation system including a content catalog and a host broker system. The content catalog contains an identification of each content file, the segmented subunits of each file, and the peer caches to which the subunits have been distributed. The host broker system receives content file requests issued over a network from requesting computers. In response, manifest files identifying the request corresponding content subunits and distributed cache locations are returned. The requesting computers can then retrieve and assemble the corresponding content subunits from the peer computers to obtain the requested content file.

A multichannel wireless digital audio distribution system provides for the synchronization of the output of audio data by different receiving units set to output audio data for receiver unit assigned channels. The transmitter includes parallel data respectively representing a plurality of audio data channels in each data packet. The data packets are broadcast wirelessly with known, predetermined packets including a timing marker. Each receiver unit receives the broadcast data packets and selects the parallel data respectively representing the receiver unit assigned audio data channel. The receiver unit outputs the selected data synchronized to the receipt of the timing marker by the receiving unit.

High quality, controlled latency multi-channel wireless digital audio distribution system and methods

A controller for controlling operation of a solar power system is disclosed. The controller receives electrical power from an energy capture device and outputs electrical power to one or more external loads. The controller initiates a first maximum power point tracking algorithm during an epoch. The controller then determines whether the first maximum power point tracking algorithm is satisfactory. If it is, the controller continues using the first maximum power point tracking algorithm. If it is not, the controller switches to second maximum power point tracking algorithm. The first and second maximum power point tracking algorithms may be optimized for different environmental conditions, such as different amounts of sunlight incident on a solar panel.

Selective multi-phase maximum power point tracking

A hierarchical content distribution system includes a seeding server, a plurality of geographically distributed content platforms, and a distribution controller, all interconnected by a communications network. The seeding server initially receives content files for distribution to various content platforms that provide for the persistent storage of the content files. Each content platform includes a content file server responsive on-demand to requests for the transfer of content files. The distribution controller autonomously monitors the transfers of content files and selectively issues transfer directives to the content platforms to modify the distribution of content files among the content platforms. The content file servers respond to received transfer directives by issuing requests for the transfer of the directive identified content files, thereby conforming the specific distribution of content files to an optimal distribution pattern as determined by the distribution controller based on usage patterns.

Media content, including content suitable for streaming, is distributed to and accessible over a communications network by computer nodes within a peer storage network of computer nodes hosting respective content stores. Discrete portions of a content file are multiply distributed to and persisted in a distributed set of the content stores existing within the storage network such that various content stores persist subsets of the content file portions. A computer node retrieves the discrete portions of the content file from the various distributed content stores, depending on node availability, the particular discrete portions there available, and node and network performance factors sufficient to maintain a minimum quality of service, thereby enabling streaming presentation of the content file on the requesting computer node.

With an array of speakers including a center speaker provided with left and right ultrasonic electro-acoustic transducers and left and right speakers provided with respective ultrasonic electro-acoustic transducers, it is possible to identify the left and right speakers. One approach includes energizing the left transducer of the center speaker to emit an acoustic ping signal, utilizing the transducers of the left and right speakers to detect the ping signal, measuring lapse of time between emission of the ping signal by said the left transducer and detection of the ping signal by the transducers of the left and right speakers. Then, the right transducer of the center speaker is energized to emit an acoustic ping signal, the transducers of the left and right speakers are utilized to detect the ping signal, and lapse of time between emission of the ping signal by the right transducer and detection of the ping signal by the transducers of the left and right speakers is measured.

A multi-source peer content distribution system transfers content files from multiple, distributed peer computers to any requesting computer. The content distribution network coordinates file transfers through a mediation system including s content catalog and a host broker system. The content catalog contains an identification of each content file, the segmented subunits of each file, and the peer caches to which the subunits have been distributed. The host broker system receives content file requests issued over a network from requesting computers. In response, manifest files identifying the request corresponding content subunits and distributed cache locations are returned. The requesting computers can then retrieve and assemble the corresponding content subunits from the peer computers to obtain the requested content file.

An apparatus and method for error free loading of a programmable non-volatile memory device over a serial or parallel data link. The apparatus comprises a host system connected to a unit to be programmed via a data communications link. The host system comprises a central processing unit (CPU) coupled to random access memory (RAM) via a bus, and the unit to be programmed represents a device in which a programmable non-volatile memory is installed. The data to be stored in the programmable non-volatile memory is sent by the host system in data packets to allow error checking to be applied to each block transmitted across the data communications link to the unit to be programmed. The host system builds data blocks in frames, computes an error detection code, and sends the frames containing the data and the error detection code across the data link to the unit to be programmed. The unit to be programmed uses the error detection code to determine if the transmission was successful. If the transfer was error free, the data is loaded into the programmable non-volatile memory in the unit to be programmed. If the frame was received in error, the unit to be programmed sends a frame back to the host system notifying it that the transmission contained an error. This process of sending and acknowledging frames continues until the programmable non-volatile memory in the unit to be programmed is completely programmed.
