    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.

    摘要: 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.
