摘要： A ring-opening metathesis polymerisation (ROMP) reaction is disclosed in which a cyclic alkene compound is subjected to ROMP using a ruthenium ROMP catalyst having heterocyclic ligands in the presence of a compound from which such ligans may be derived. The process includes the step of adding sufficient of an acyclic alkene having a carbon-carbon double bond capable of reacting with the catalytic metal moieties attached to the living end of each of the polymer chains generated in the ROMP reaction to end cap the polymer chains and to generate a olefin metathesis catalyst. The process includes reiterating the polymerisation steps by adding further amounts of a cyclic alkene compound. The catalyst may be generated in situ from a precursor compound by the addition of a compound from which heterocyclic ligands may be derived by interaction with the precursor compound.

摘要： Instant messaging clients transmit, to a server, presence information indicating that the respective client is in a communicative state in which the client is receptive to communicating with the other clients. A server determines, for each client, that the respective client is in a communicative state if presence information was received from the client over a preceding predetermined time period, and that the client is in an unknown state if presence information was not received from the client over the preceding predetermined time period. The communicative state and the unknown state are possible presence states of the clients. The server transmits a notification to a second client of the presence state of a first client when both the first client and the second client are in a communicative state. But the server refrains from transmitting the notification to the second client when the first client is in the unknown state.

摘要： A method of operating a server includes receiving a single message, from a messaging client, addressed to a group. The group is resolved to user identifiers that identify both wireless device clients and Internet clients. A message is sent to each of the wireless device clients and each of the Internet clients.

摘要： A system and method of instant messaging is provided. A plurality of messaging clients capable of transmitting instant messages to one another are each configured to share presence information with one another via a network. A determination is made, with respect to each of the messaging clients, as to whether the messaging client is in a state in which it is receptive to receiving presence information from the other messaging clients, and if so, then the presence information is provided to the messaging client. The presence information may be provided directly between the messaging clients, or it may be provided through one or more centralized proxy servers that store and propagate the presence information. A special state is provided, referred to herein as the unknown state, which when entered by a particular messaging client will cause the system to cease further transmissions of presence information to that client and/or transmissions about that client. Upon changing to a communicative state, the system resumes providing presence information to/about the messaging client.
摘要翻译： 提供了即时通讯的系统和方法。 能够将即时消息发送给彼此的多个消息收发客户端都被配置为经由网络彼此共享存在信息。 对于每个消息传递客户端，确定消息接发客户端是否处于其接收来自其他消息收发客户端的存在信息的状态，如果是，则将该呈现信息提供给 消息传递客户端。 存在信息可以直接在消息客户端之间提供，或者可以通过存储和传播存在信息的一个或多个集中式代理服务器来提供。 提供了一种特殊状态，这里称为未知状态，当由特定消息传递客户端输入时将导致系统停止对该客户端的存在信息的进一步传输和/或关于该客户端的传输。 在改变为交际状态时，系统恢复向消息传递客户端提供存在信息。
