    摘要: A paddle for watercraft has a shaft to which blades are attached at opposite ends. The blades may be mounted directly to the shaft or via drop cranks. The shaft is suspended on handles oriented transversely to the shaft's longitudinal axis. The handles are capable of pivoting motion relative to the shaft as well as rotational motion about their respective longitudinal axes.

    摘要: A mobile ad-hoc network includes a plurality of N mobile nodes and wireless communication links connecting the mobile nodes, which each include a communications device for transmitting and routing data packets wirelessly to other mobile nodes via the wireless communication links in accordance with a time division multiple access (TDMA) data transmission protocol using a TDMA epoch that is divided into a beacon interval, digital voice interval and digital data interval. The mobile nodes monitor channel conditions using the beacon, digital voice and digital data intervals and provide a network conductivity performance as valid receptions occur within mobile nodes. A data rate is calculated and set for other N−1 mobile nodes using monitored channel conditions for the beacon, digital voice and digital data intervals.

    摘要: An improved method is provided for decoding data in a frequency hopping communications system. The method includes: monitoring transition points between data bits in a demodulated data stream, where the data bits are transmitted to a receiver over different transmission frequencies; determining a frequency over which data bits are transmitted to the receiver; determining a reliability metric for each frequency over which data bits were received, where the reliability metric is based on transition points of data bits transmitted over a given frequency; and performing a decoding operation using the reliability metric for each frequency over which data bits were received.

    摘要: An improved method is provided for identifying a repeated codeword in an incoming bit stream. The method includes: receiving an incoming bit stream having an expected codeword repeated a number of times; determining whether a group of incoming data bits correlates to the expected codeword, where each of the incoming data bits in the group need not match the corresponding data bit of the expected codeword; and determining whether the expected code word is repeated over a sequence of incoming data bits
