摘要:
A communication scheme for a multi station message transmission system involves the transmission of messages from one station to another, a return message from the receiving station and the retransmission of a previously transmitted message if an acknowledgement is not received. Each message, which may or may not contain data, includes a header having a sequence bit and an acknowledge bit. Each station within the communication system stores in memory a transmit sequence bit and a receive sequence bit. The header of each message that is transmitted from a given station contains a sequence bit corresponding to the state of the transmit sequence bit stored at that station. When a message having an acknowledge bit is received, the state of the stored transmit sequence bit is switched. Upon receipt of a data message having a sequence bit that corresponds to that of the stored received sequence bit at that station, the state of the stored received sequence bit is switched and an acknowledge bit-containing message is returned. If the acknowledge bit is not received from receiving station in a predetermined time after the initial transmission, the previously transmitted message is retransmitted. When the state of the sequence bit in the message is different from that of the received sequence bit stored at the station, and incoming message is disregarded.

A method and system for converting a feedstock using thermal plasma or other gassifier, into a feedwater or make up water energy transfer system. Feedstock is any organic material or fossil fuel. The energy transferred in the feedwater or make N up water is used in any Rankine or other steam process, or any process that requires heat. Heat is extracted from a gas product issued by a gassifier and is delivered to a power plant via its feedwater system or make up water system. Preferably, the gassifier is a plasma gassifier and the gas product is syngas that is combusted in an afterburner. A heated air flow and/or EGR flow is provided the afterburner at a variable flow rate that is responsive an operating characteristic of the afterburner.

An entertainment device is configured to receive a limited range wireless signal from at least one other entertainment device when adjacently arranged in close physical proximity to at least one other entertainment device, and to responsively operate in a first mode or a second mode based on whether the other entertainment device is adjacent a first side or second side. In the first mode, the entertainment device initiates one or more wireless activation signals to control an audio/visual element of another entertainment device. In the second mode, the entertainment device receives wireless activation signals from another entertainment device to control activation of an audio/visual element of the receiving entertainment device. Each device is interchangeable between operation in the first mode of controlling at least one other entertainment device and the second mode of being controlled by another entertainment device based on position of one entertainment device relative to the other.

摘要:
An apparatus for placement into an opening formed in a wall of a body lumen to deploy a closure element. The apparatus comprising a housing having a handle portion formed at a distal end, the handle portion configured to be engaged by a user when advancing the housing to deploy the closure element. A triggering element deploys the closure device and can at least be partially formed in the housing. A throw reducing mechanism can slide relative to the housing and reduce the distance a user must stretch a hand to move a triggering system within the housing. The housing can include, or be connected to, a handle member having one or more expansion members which expand to provide a stable base for manipulating the apparatus.
摘要:
A method for modulating a content signal (18) to contain an auxiliary signal, the content signal (18) having content segments, the method comprising logging detections of a test content signal (20) to create one or more log files (44); parsing the one or more log files (44) to create a profile file (46); scheduling the profile file (46) to create an encode file (48); and encoding the content signal (18) with the auxiliary signal according to the encode file (48) and a modulation method.
