30 results about "Web Messaging" patented technology

Web Messaging or cross-document messaging, is an API introduced in the WHATWG HTML5 draft specification, allowing documents to communicate with one another across different origins, or source domains while rendered in a web browser. Prior to HTML5, web browsers disallowed cross-site scripting, to protect against security attacks. This practice barred communication between non-hostile pages as well, making document interaction of any kind difficult. Cross-document messaging allows scripts to interact across these boundaries, while providing a rudimentary level of security.

System and method for online collaboration in a learning environment

A system and method is provided for the collection and automate dispatching of assignments and news from a teacher to their students and parents. This involves registering members and assigning them roles, scopes and groups based on scheduling and other data pulled from the school/district's database, capturing assignment data from the teacher or student assistant through a web form, constructing custom homepages and assignment messages for each student and parents, and transmitting those messages to the right parties. Additionally, a system and method for relationship-based messaging between members to facilitate communication made difficult or impossible in a traditional school environment. This involves assigning roles and defining the relationships between those roles (factoring in scheduling information), granting and limiting publishing scope based on the same, and providing a system for web messaging and email distribution. Finally, a system and method for creating student digital portfolios. This involves aggregating information already published to the system along with grades and attendance information pulled from the SIS, student work submitted through digital dropboxes, plans and comments from teachers and staff, membership data, and school participation data as expressed through membership and messaging through the system. This information is available on a single web page accessed through directories, rosters and special groups by school and district staff.

Priority rules for reducing network message routing latency

A system and method is disclosed for reducing network message passing latency in a distributed multiprocessing computer system that contains a plurality of microprocessors in a computer network, each microprocessor including router logic to route message packets prioritized in importance by the type of message packet, age of the message packet, and the source of the message packet. The microprocessors each include a plurality of network input ports connected to corresponding local arbiters in the router. The local arbiters are each able to select a message packet from the message packets waiting at the associated network input port. Microprocessor input ports and microprocessor output ports in the microprocessor allow the exchange of message packets between hardware functional units in the microprocessor and between the microprocessors. The microprocessor input ports are similarly each coupled to corresponding local arbiters in the router. Each of the local arbiters is able to select a message packet among the message packets waiting at the microprocessor input port. Global arbiters in the router connected to the network output ports and microprocessor output ports select a message packet from message packets nominated by the local arbiters of the network input ports and microprocessor input ports. The local arbiters connected to each network input port or microprocessor input port will request service from a output port global arbiter for a message packet based on the message packet type if the message packet is ready to be dispatched.

A method of real-time message transmission among multi-robots

ActiveCN105429858BTransmission delay controlGuaranteed automatic deathData switching networksMessage deliveryWeb Messaging
The invention discloses a method for transmitting real-time messages among multiple robots. The purpose is to provide support for real-time transmission of network messages based on ROS at the robot middleware layer, so that the process of message transmission between multiple robots can meet the requirements of priority and transmission delay. Wait for time constraints. The technical solution is to introduce DDS, a network messaging specification with real-time guarantee capability, into ROS. First, build a multi-robot computing node environment. In this environment, the operating system Ubuntu, robot middleware ROS, and message real-time middleware that comply with DDS specifications are built. And the ROS / DDS protocol plug-in, the ROS / DDS protocol plug-in supports the real-time attribute setting of ROS messages, and realizes the mutual conversion between ROS messages and DDS messages, and uses the real-time message middleware that conforms to the DDS specification to send and receive messages. By adopting the present invention, under the condition that the existing multi-robot distributed application directly uses the ROS / DDS protocol plug-in without modification, the real-time performance of message transmission among multi-robots can be realized at the robot middleware layer.
