A method for performing end-to-end “tree-based ordered multicasting” (TOM) which ensures collective integrity and consistency of distributed operations, and which is applicable to distributed multiparty collaboration and other multipoint applications. The TOM protocol performs cascaded total ordering of messages among on-tree hosts en route from senders to receivers, and does not require the building of a separate propagation graph to compute ordering information. TOM elects sequencer nodes dynamically based on address extensions of the multicast tree. Message ordering is performed by multicasting a message from each source node to receivers, unicasting a control message from a source node across a primary node to an ordering node for the designated multicast group or transmission in the tree, determining a binding sequence number for the message and a multicast to the receiver group, and delivering messages at end hosts according to the agreed-upon sequence numbers.

Apparatuses, methods and systems relating to at least one or more of golf club reminding and golf data collecting and recording. In one embodiment an apparatus on a golf club includes an integrated reminder and a stroke cancellation system and is semi-automatic in that the recording of the stroke is directly in response to changing the state (e.g. activating) of a switch which indicates that the golfer has pressed a button on the golf club. The pressing of the button indicates that the golfer will or has taken a stroke with the golf club and that the stroke is to be recorded, with the location of the stroke and an identifier of the club (e.g. 9 iron). The system may also be equipped with a missing club reminder and theft prevention function that notifies the golfer is a golf club has been left behind or if a club or golf bag has been removed without authorization.

A system for delivering streamed content over a large digital network such as the Internet. Distributed functionality executes on nodes in the network to achieve functions such as assigning partner nodes for transfer of content to or from a target node, scheduling transfer operations among nodes, adding or removing nodes from the network, maintaining security, and other operations. Different embodiments may use one or more of the functional features. In a preferred embodiment, video content is segmented and streamed through multi-path routing. An overlay network uses nodes in partnership groups so that a target node can obtain segments from multiple sources. Partner nodes can provide the segments within a given time window, including simultaneous delivery from multiple partner nodes, so that a more reliable data stream is supported.

Sparse signal modulation schemes encode a data channel on a host image in a manner that is robust, flexible to achieve perceptual quality constraints, and provides improved data capacity. The host image is printed by any of a variety of means to apply the image, with sparse signal, to an object. After image capture of the object, a decoder processes the captured image to detect and extract data modulated into the sparse signal. The sparse signal may incorporate implicit or explicit synchronization components, which are either formed from the data signal or are complementary to it.

An external transmitter circuit drives an implantable neural stimulator having an implanted coil from a primary coil driven by a power amplifier. For efficient power consumption, the transmitter output circuit (which includes the primary coil driven by the power amplifier inductively coupled with the implanted coil) operates as a tuned resonant circuit. When operating as a tuned resonant circuit, it is difficult to modulate the carrier signal with data having sharp rise and fall times without using a high power modulation amplifier. Sharp rise and fall times are needed in order to ensure reliable data transmission. To overcome this difficulty, the present invention includes an output switch that selectively inserts a resistor in the transmitter output coil circuit in order to de-tune the resonant circuit only during those times when data modulation is needed. Such de-tuning allows sharp rise and fall times in the data modulation without the need for using a high power modulation amplifier. Because data modulation is typically needed for only a small percent of the time that a carrier signal is present, it is thus possible using the present invention to achieve reliable data modulation, transmission and reception without having to use a high power modulation amplifier in the transmitter.
