Abstract: A culling buoy holder that includes multiple tubes laid side by side in a parallel fashion and affixed to a mounting structure or to each other. The tubes are sized in length and diameter such that a culling buoy may be inserted down through the bore of a tube, with a float first orientation, until the float dangles below the lower open end of the tube. Further, while tube bore sizes are large enough to permit the passing of a buoy float, they are small enough that the clipping apparatus comprising the opposite end of the buoy cannot pass. Advantageously, each buoy, once inserted through an individual tube of the buoy holder, is effectively separated from other buoys as it securely hangs in its individual tube.

Abstract: A method and apparatus for assigning a unique network address to a first node within a network which is arbitrarily connected. The first node may include a shared network resource, such as a networked printer device, or a modem, in addition to a stand-alone computer system. The network may include a network which is wireless, wherein various nodes comprise radio transceiver circuitry, including radio frequency modems. A first provisional network address for use in assigning the unique network address is determined by the first node. The first node broadcasts probes containing the provisional network address until a first probe response to one of the probes is received or a first interval of time elapses. If the first probe response to one of the probes is received, then the first node determines a second provisional network address and repeats selection of the address and broadcasting, until no probe response is received in the first interval of time.

Abstract: In a communication system including a plurality of networked stations that communicate using a slow frequency hopping system, a method for encoding a packet of data in a transmitting station and decoding the data in a receiving station. In the transmitting station, the packet is divided into data segments. Error correction segments are added to correct the data segments. The segments are fragmented into a series of fragments, and a data error control field is calculated for each fragment and appended thereto. The data units including the segments are transmitted, and in a receiving station all or a portion of the bursts are received. The DEC field for each received fragment is calculated and compared with the received DEC field to determine whether each fragment is good or bad. If there are a sufficient number of fragments in each column, then the data can be reconstructed.

Abstract: A multiplexed synchronous/asynchronous data bus is disclosed in which three bus lines are used to convey bidirectional synchronous data between at least two data devices at a relatively low data rate. Valid half duplex asynchronous data is applied at a higher data transfer rate to one of the three bus lines when only one of the bus lines is held in a logic high state.

Abstract: A process for use in a radiotelephone that has multiple telephone numbers for use in different cellular radiotelephone systems. The numbers are stored in number assignment modules (NAM's) with its corresponding system identification code. The process compares a received system identification code with the ones in memory (103). If a match is found, the radiotelephone user is prompted to select the new telephone number (104). If the new number is not selected or the identification code is not found in memory, the radiotelephone becomes a roaming unit and enters an idle state (107) waiting for an incoming call.

Abstract: A cellular radiotelephone autonomous registration method. The radiotelephone attempts registration when a clock count transmitted by the system equals or exceeds the radiotelephone's threshold count (201). The radiotelephone then scans (202) available channels for proper signal strength and attempts to seize that channel (203). If the channel seizure fails, the threshold count is updated with the clock count plus a random integer (207) and the next channel seizure attempt is made when the next master clock value equals or exceeds this value. This method increases the length of time between failed channel seizure attempts, thereby decreasing the load on the radiotelephone's power source.

Abstract: A multiplexed synchronous/asynchronous data bus is disclosed in which three bus lines are used to convey bidirectional synchronous data between at least two data devices at a relatively low data rate. Half duplex asynchronous data is applied at a higher data transfer rate to one of the three bus lines when another of the bus lines is held in a logic high state.

Abstract: A radiotelephone subscriber unit which overcomes the problem of attempting to access an undesired radiotelephone system is disclosed. A comparison between the system identification transmitted on a control channel of a desired radiotelephone system and the system identification transmitted on an access channel is made during the access process of the subscriber unit. Access is permitted if the control channel system identification and the access channel system identification match.
