A system and method for tracking rental equipment such as fleet watercraft is disclosed. The system and method includes a communication system and a waterproof and weatherproof GPS tracking device that is easily attached to each watercraft and integrated into the communication system. The communication system further includes a client application running on a client computing tracking device. The client application can receive GPS tracking data from the GPS tracking device, interpret the data in various beneficial ways, and graphically display the interpreted data.

Method and apparatus for fleet management of equipment

A BCN network with BCN modems that enable network wired devices to communicate over a typical home coaxial network that may include passive splitters and different types of coaxial cable.

Broadband local area network

A waterproof apparatus including a waterproof enclosure including electronic circuitry, a solar panel and a keypad. The electronic circuitry is configured to communicate data wirelessly when pressure is applied to the keypad. The waterproof apparatus may be mounted to watersport equipment, such as a surfboard, kiteboard, kayak, wind surfer jet ski, paddle board, or a wakeboard.

Waterproof wireless communications and methods for water-based apparatus

A BCN network with BCN modems that communicate using predefined messages to establish, optimize and facilitate data communication.

Multimedia over coaxial cable access protocol

A physical layer transmitter that communicates between nodes in a broadband cable network by transmitting and receiving packets containing data and control information. Packets are constructed by the physical layer transmitter and transmitted to one or more receiving nodes that are capable of processing the packets. Packets are directed to specific nodes utilizing link layer control data. The packets may also contain control information that may include formatting, encoding and modulation parameters that are capable of being processed by the appropriate receiving nodes. The physical layer transmitter allows node-to-node communication within a broadband cable network and each node in the network is capable of communicating with every other node in the network.

Physical layer transmitter for use in a broadband local area network

A local area network uses coaxial cable wiring for interconnection of terminal devices. A frequency selective network interface device is placed at the building point of entry or another point in the wiring to reflect network signals transmitted by terminal devices back into the building distribution to be received by other terminal devices. By reflecting network upstream signals back into the building as downstream signals, the network interface provides a path for terminal devices to transmit to and receive from other terminal devices.

A method and apparatus for processing demodulated data comprising received symbol data is disclosed. A decoder is used to compute estimated symbols and corresponding reliability metrics. The reliability metrics are transformed into reliability weights. Optionally, residuals relating to the difference between the received symbol data and the estimated symbols are computed. Output data are generated comprising any combination of the following: estimated symbols, reliability weights, residuals, and received symbol data. The residuals may be weighted by the reliability metrics and used by demodulation or error compensation loops to instantaneously reduce or increase the bandwidth of these loops.

Symbol reliability determination and symbol pre-selection based on reliability criteria

A soft trellis slicer is provided in a high definition television (HDTV) receiver. The soft trellis slicer calculates a decision value and a confidence value corresponding to a phase angle error of a signal processed by the receiver. The receiver includes an equalizer, a phase tracking loop and a trellis decoder. The equalizer provides an equalized signal to the phase tracking loop; and the phase tracking loop calculates a phase angle error for the equalized signal. The trellis decoder calculates a decision value and a confidence value. The trellis decoder provides the decision value and the confidence value to the phase tracking loop, which calculates the reliability of the phase angle error based upon the phase angle error and the decision value and the confidence value provided by the trellis decoder. The trellis decoder calculates the decision value based upon a best path metric and calculates the confidence value based upon the best path metric and a second best path metric.

Soft trellis slicer for improving the performance of a decision-directed phase tracker

A system for carrier phase tracking of symbols. In an embodiment employing a feedback structure, a symbol derotator pre-rotates a symbol by a derotation phase. A symbol and reliability estimation engine provides, responsive to the pre-rotated symbol, an estimate of the symbol and a reliability metric for the estimate. A tracking loop module determines a residual between the pre-rotated symbol and the symbol estimate, weights the residual by the reliability metric for the estimate, and determines a phase offset estimate responsive to the weighted residual. An accumulator then determines a next derotation phase responsive to the phase offset estimate. In an embodiment employing a feedforward structure, a symbol and reliability estimation engine provides an estimate of a symbol and a reliability metric for the estimate. A tracking loop module determines a residual between the symbol and the symbol estimate, weights the residual by the reliability metric for the estimate, and determines a derotation phase responsive to the weighted residual.
