摘要:
A chat system includes a chat server and a plurality of chat clients in a network that may be bandwidth constrained. Each chat client is configurable, in response to instructions from the chat server, to operate in either a master mode or a slave mode. In the master mode, a chat client is capable of initiating a chat session. In the slave mode, a chat client is incapable of initiating a chat session and may participate only in a chat session initiated by another chat client operating in the master mode. An invitor user initiates, or adds a member to, a chat session by sending an invitation to an invitee user name at a proxy address at the chat server. If the chat server determines that the invitee is logged on, the chat server forwards the invitation to the invitee at the invitee's network address. If the invitee user accepts the invitation, the invitee client sends a join message to the invitor client, and the invitor client adds the invitee's user name and client network address to a chat member list. Then, the chat session proceeds with the chat member client sending chat input to the master client and the master client sending chat session updates to the member client.

That a trigger for creating a temporary collaborative ad-hoc network of hardware nodes has occurred is detected. In response, the temporary collaborative ad-hoc network is created via intercommunication among the hardware nodes. After the temporary collaborative ad-hoc network has been created, the temporary collaborative ad-hoc network performs a given function. A particular hardware node within the temporary collaborative ad-hoc network can perform a roll call request so that it ascertains a list of the hardware nodes within the temporary collaborative ad-hoc network. Performing the roll call request can include ascertaining that a correctness of the list of the hardware nodes satisfies a threshold, such that the correctness of the list of the hardware nodes is not necessarily completely correct.

Use of and performance of ostomy appliances are enhanced by providing one or more sensors to an ostomy pouch; collecting sensor data by sensors to form a history of events impinging on the ostomy pouch and conditions of the pouch over time; comparing the sensor data to historical sensor data for a similar ostomy pouch to predict a reduction in nominal wear time; and notifying a user of the predicted reduction in nominal wear time.

A data processing system and a computer program product for monitoring water consumption. A set of locations in a fluid transport system in a structure is monitored for sounds generated by a fluid flowing at an endpoint of the fluid transport system. Current acoustic data is generated for the sounds detected from monitoring the set of locations. The current acoustic data is compared with historical acoustic data to form a difference. A determination is made as to whether the difference exceeds a threshold. An action is performed in response to determining that the difference exceeds the threshold.

Electrical power is generated from falling liquids such as captured rain water, gray water and black water in tall buildings using two or more reservoirs. Fill valves for each of the reservoirs are controlled to fill the first reservoir in a raised position while emptying the second reservoir in a lowered position. When full, the first reservoir is dropped to the lowered position while imparting mechanical energy to an electrical generator and while raising the second reservoir. Next, the second reservoir is filled until full while the first reservoir is emptied, followed by dropping the second reservoir to the lowered position while imparting mechanical energy to the electrical generator and while raising the first reservoir. The cycle is repeated so that electrical generation from the falling of the liquid avoids the liquid contacting or passing through a turbine or impeller.
