  • Patent number: 7420877
    Abstract: In a method for processing an echo profile generated by a pulse-echo ranging system, the echo profile is compared with a time-varying threshold function to identify valid echoes in those portions of the echo profile which exceed the TVT function. Based on the amplitude and/or area above the TVT function, each echo is rated and attributed a level of confidence. The echo with the highest level of confidence is selected as the echo of interest, and the level of confidence is reported. To provide an improved echo processing with increased accuracy in determining the confidence level of the selected echo of interest, it is furthermore determined whether the portion of the threshold function which timely corresponds to the selected echo of interest is part of a hump-shaped section of the threshold function. If so, said section is reshaped to reduced hump amplitude, and the confidence level of the echo of interest is redetermined based on the amplitude and/or area above the reshaped TVT function.

    Abstract: The present invention discloses an optical information recording method of an optical information recording and reproduction device that uses a semiconductor laser to record or reproduce data in an optical disk. Based on a detected value of an optical path difference of the optical disk, a calculated value of optimum recording power for recording data or an object value of recording power when data are being recorded is corrected. In addition, when calculating the optimum recording power before recording data in the optical disk, an optimum index (?) indicating the optimum recording power is corrected with respect to a predetermined first index, and the corrected optimum index is used as the calculated value of the optimum recording power Pwo. The predetermined first index is obtained by reproducing a trial write region which is recorded with recording power being varied stepwise.

  • Patent number: 7420903
    Abstract: Disclosed is electronic equipment enjoying improved ease of use, and a highlighting method and a program to be implemented or installed in the electronic equipment. For example, a user performs manipulations so as to reproduce a content up to the middle of the content, and then turns off a power supply. When the user turns on the power supply next, a playback selection menu screen image is displayed and “Playback from the middle thereof” is highlighted. Consequently, when the user wants to reproduce the content from the middle of the content, the user need not worry about whether to reproduce the content from the beginning or the middle thereof. The user should merely finalize the highlighted item. This would prove user-friendly and helpful. When the electronic equipment is used outdoors or the like, the number of manipulations to be performed on the equipment is smaller than the number of manipulations conventionally performed.

    Abstract: A bidirectional communication system is provided. In one embodiment, a system comprises a host unit and a plurality of remote units using a multiple access scheme to communicate at the same time with the host unit using orthogonal frequency division multiplexing (OFDM). The host unit repeatedly performs an analysis of a transmission characteristic of at least one upstream signal from at least one remote unit. The at least one remote unit makes adjustments to the transmission characteristic based on the analyses performed by the host unit to assist the host unit in demodulating a plurality of upstream signals from the plurality of remote units.

    Abstract: In the reception of a downlink MIMO CDMA signal, the receiving unit performs a simplified process of linear equalization that eliminates the need for inverting the correlation matrix. The correlation matrix is approximated to a good degree by a circulation matrix that is diagonalized by FFT operations, thus substituting two FFTs and one IFFT having a complexity of O ( L F ? ( N ? ? ? ) 3 + ( N ? ? ? ) 2 + 2 ? ( N ? ? ? ) 2 ? L F ? log 2 ? L F ) for the direct matrix inversion having a complexity of O(LF3).

  • Patent number: 7420917
    Abstract: In a bandwidth policing apparatus which accommodates a large number of user groups, bandwidth policing for each user group is performed at high speed. When there is any extra bandwidth in bandwidth for a user group, the contracted committed information rate for each user is guaranteed invariably while using this effectively. The bandwidth policing apparatus accumulates packets of a plurality of user groups under bandwidth policing in the same packet accumulate FIFO. Also, for a packet which does not exceed the contracted bandwidth for each user, the contracted bandwidth for each user is guaranteed by deciding that the packet does not exceed the contracted bandwidth for each user group.

  • Patent number: 7420918
    Abstract: A Look-ahead Contention Resolution (“LCR”) technique for application in burst switching networks is described. The LCR technique takes advantage of the existing separation of data bursts and their BHPs in time (offset or “?”). Through a look-ahead window (“LAW”) W time units wide, a network scheduler can process a group of BHPs prior to the arrival of their respective bursts and gain a collective knowledge of the state of the switch in the futures, rather than processing a single slot ? time units in the future.

  • Patent number: 7420919
    Abstract: Self converging communication fair rate control systems and methods of the present invention facilitate fair utilization of node buffers and optimized utilization of available bandwidth. A self converging communication fair rate control method provides a fair rate that is utilized to determine a connection rate for communicating information from a plurality of virtual connection queues to a class of service buffer (COSB). The self converging communication fair rate control method includes establishing a self-convergence factor, determining a buffer flow ratio, and adjusting a fair rate value based upon the buffer flow ratio and the self-convergence factor. The buffer is divided into buffer fill regions designated by fair rate convergence-adaptation thresholds and are associated with self-convergence factors. The fair rate self-convergence factors dynamically decrease fair rate values that result in a buffer filling up and increase fair rate values that result in a buffer emptying out.

  • Patent number: 7420921
    Abstract: Aggregated fragment acknowledgement in a LAN. A transmitter sends a data packet to a receiver. The receiver then constructs an AFAF and sends that AFAF back to a transmitter. The transmitter is then able to determine the success and/or failure, in full or in part, of the transmission of the data packet to the receiver. A very precise granularity, or resolution, of the success of the transmission may be achieved on a per fragment basis. Bandwidth savings may also be achieved. When no resolution on a fragment basis is required, then that level of resolution is not employed. The resolution of the fragment basis may be adaptively employed when required to notify the transmitter of the status of one or more fragments within a data packet.
