Systems and methods for providing resource management in a distributed network are disclosed. A loose collection of devices in a network may not be aware of the power restrictions for other devices. Wall powered devices will generally have drastically different power settings than battery powered mobile devices. The invention provides a federation policy for time that can be used to slave to a local service responsible for understanding the local resource requirements of each device (or node) on the network. In such a distributed time system, all services in a particular time domain may be sped up, slowed down, or completely halted.

Resource management via periodic distributed time

Methods, devices, and systems for performing intermittent detection during analytical reactions are provided. Such methods facilitate collection of reaction data from disparate reaction times. Further, such methods are useful for reducing photo-induced damage of one or more reactants in an illuminated analytical reaction at a given reaction time. In preferred embodiments, the reaction mixture is subjected to at least one illuminated and non-illuminated period and allowed to proceed such that the time in which the reaction mixture is illuminated is less than a photo-induced damage threshold period.

Systems and methods for compositing an image directly from multiple source image data for reducing system memory footprint and bandwidth and for improving color quality of the image. The image is divided into spans, lines, and slices. Each line includes at least one span and each slice includes at least one line. All lines in a slice have spans associated with identical sources. An image is composited by reading the image data directly from one or more sources of each span. If necessary, the sources are blended. A control structure is used to provide the image context and identifies the sources of the spans. The control structure includes headers for each data stream from each source of each span. Also, the color quality of the image is improved by reducing the number of color space conversions that occur as the image is composited. All sources in the same color space are blended before being blended with sources from other color spaces. Preferably, no more than a single color conversion is required.

Systems for servicing the data and memory requirements of system devices. A DMA engine that includes a data reservoir is provided that manages and arbitrates the data requests from the system devices. An arbitration unit is provided that only allows eligible devices to make a data request in any given cycle to ensure that all devices will be serviced within a programmable time period. The data reservoir contains the data buffers for each channel of each device. A memory interface ensures that sufficient data for each channel is present in the data reservoir by making requests to a system's memory based on an analysis of each channel. Based on this analysis, a request is either made to the system's main memory, or the channel waits until it is evaluated again in the future. Each channel is thereby guaranteed a response time.

Arbitrating and servicing polychronous data requests in direct memory access

Real-time communication of multimedia data over heterogeneous networks that may include constant delay networks, variable delay networks that have a common reckoning of time, and variable delay networks that do not have a common reckoning of time. If there are any variable delay networks in which there is no common reckoning of time in the heterogeneous networks, a common reckoning of time is established in each of those networks. Then, a constant delay network is emulated for each variable delay network using the specific common time reckoning present in each variable delay network.

Methods and systems for distributing multimedia data over heterogeneous networks

The present invention is directed to a method and system for disaggregating and connecting A/V components, and communicating A/V content stream information. An A/V stream from a source device is packaged for transmission over an IP network to one or more output devices. A brick device enables the integration of legacy A/V systems into the network supported A/V system. The brick device operates to provide analog signal and IP protocol conversion, along with the synchronization of received A/V stream data packets. The rendering and play of the A/V stream content on multiple output devices is synchronized to overcome distortions and other network idiosyncrasy and to facilitate a pleasant user experience.

Method and system for disaggregating audio/visual components

A radio module that detachably connects with a host device. A radio module is provided that includes an antenna as an integral part of the radio module. The antenna satisfies regulatory requirements by being an integral part of the radio module. The radio module includes an interface circuit that provides the processing required for communication over a wireless network. The functionality of the interface can be divided between the radio module and the host device. The physical interface between a host device and the radio module may depend on which functions are implemented by the radio module and which functions are implemented by the host device. In one example, the physical interface is a standard connection that permits the radio module to be detachably connected with multiple devices. The radio module also includes a flexible cable such that the radio module can be optimally positioned within the wireless network.

A switch with tandem ports and an outlet assembly permit individual segments of cable to be used with multiple data link protocol standards. The multiple data link protocols can be used either one at a time, with each group of wires in the cable carrying the same data link protocol in different communication sessions, or can be used in tandem, with each group of wires in the cable simultaneously carrying a different data link protocol.

Arbitrating and servicing polychronous data requests in Direct Memory Access

A new network connection setup procedure for network computers to set up data transmission connections over a network that implements traffic prioritization (e.g., according to IEEE 802.1p) has the effect of providing admission control and implicit bandwidth reservation. A sending network device (the 'sender') that wants to initiate a new transmission over the network first enters a probing mode in which it sends data packets at a priority level that is lower than the target priority level and at a transmission rate up to a peak probing transmission rate that may be the same or slightly higher than the desired transmission rate. If the sender determines based on feedback regarding the probing transmission that the network can support a transmission at the peak probing transmission rate and the probing priority level, it switches to a steady mode in which it sends data packets at the desired transmission rate and at the target priority level.
