Abstract: TDMA communications between a host device and a number of clients on a communications channel are dynamically adapted to allocate or de-allocate time slots in response to changes in the number of active clients. The system initially operates in a startup mode in which the host device transmits a startup message on the communications channel and assigns a timeslot in a TDMA cycle in response to connection requests received from each of the requesting clients. After exiting the startup mode, the system operates in a normal mode in which the host device initiates the TDMA cycle by transmitting a polling message on the communications channel that indicates a number of timeslots occurring within that particular TDMA cycle. The host changes the number of timeslots indicated in the polling message to responsively adapt duration of the TDMA cycle as the number of clients communicating via the communications channel changes.

Abstract: Methods and apparatus for performing multiplexing of video or other content (e.g., programs) within a network using feed-back from a subsequent digital program insertion stage, and/or feed-forward information from a prior multiplexing stage. In one embodiment, the network comprises a hybrid fiber coax (HFC) cable network having headend and hub-based statistical multiplexing stages, and communication between the two stages is used to improve the visual quality performance and bandwidth utilization of the output multi-program stream during conditions where downstream content is inserted into the transport stream. Business methods associated with the various multiplexing features described above are also disclosed.

Abstract: A system and method for providing communications between a hub (medical controller) and a node (an implant) are disclosed. The hub selects an operating channel within a channel group in accordance with applicable regulations, and transmits signals to facilitate communications with nodes. A node sequentially tunes to individual channels within the group, monitoring each channel for a hub transmission during a monitoring period. If a hub transmission is detected, the node stays on the current channel. Otherwise, the node tunes to a next channel in the channel group. The hub transmission may be directed to unconnected nodes, to a single connected node, or to a group of connected nodes. The node transmits a first frame to the hub at a designated transmission time and receives a response. The node reports an emergency by sequentially transmitting emergency frames on each of the channels until receiving an acknowledgment from the hub.

Abstract: A multiplexing communication system is capable of maintaining an appropriate response speed of a control with respect to an electromagnetic motor based on an encoder signal during multiplexing and transmission of the encoder signal. A transmission data composition processing section of a multiplex communication device multiplexes encoder signals ENCD1 to ENCD8 output from a linear scale and a rotary encoder into frame data FRMD and transmits the data. The transmission data composition processing section sets the encoder signals ENCD1 to ENCD8 to bit positions of the frame data FRMD respectively corresponding to the linear scale and the rotary encoder. At the bit positions where the encoder signals ENCD1 to ENCD8 are set, the encoder signal ENCD and information showing the presence or absence of the data of the encoder signal ENCD are alternately set for each cycle of transmission of the frame data FRMD.

Abstract: A means for reliable inter-processor communication in a multi-processor system is described. In accordance with one aspect, a specially-configured serial bus is used as a general-purpose data link between a first processor and a second processor. The serial bus may be an Inter-IC Sound (I2S) bus. In accordance with another aspect, a network interface residing on a second processor is made available to a first processor via a data link established over an I2S bus. This allows the second processor to be used as a proxy and to support remote configuration and network address traversal.

Abstract: A scheduled transmission may be divided up into several segments so that a transmitting node may receive and transmit control messages between segments. In some implementations a monitoring period is defined after a scheduled transmission period to enable the transmitting node to acquire control information that may otherwise have been transmitted during the scheduled transmission period. In some implementations a wireless media access control supports asynchronous communication and overlapping transmissions. Here, a wireless node may determine whether to request or schedule a transmission based on control messages it receives from neighboring nodes. In some implementations data and control information are transmitted over different frequency division multiplexed channels to enable concurrent transmission of the data and control information.

Abstract translation: 调度的传输可以被划分成若干段，使得发送节点可以在段之间接收和发送控制消息。 在一些实施方式中，在调度的传输周期之后定义监视周期，以使得发送节点获取否则可能在调度的传输周期期间已经发送的控制信息。 在一些实现中，无线介质访问控制支持异步通信和重叠传输。 这里，无线节点可以基于从相邻节点接收到的控制消息来确定是否请求或调度传输。 在一些实施方式中，数据和控制信息通过不同的频分多路复用通道传输，以实现数据和控制信息的并发传输。
