  • Publication number: 20140270122
    Abstract: The invention provides a communication protocol and serial interface having an approximately fixed interface clock and capable of accommodating a variety of communication rates. The interface employs a variable-length frame that may be expanded or reduced to obtain a desired communication rate, even though the interface clock rate is held approximately constant. The invention further provides a method for designing an agile barrier interface. In particular, the barrier clock rate is preferably selected to be an approximate common multiple of the various communication rates that the barrier interface must handle. The frame length corresponding to each communication rate may then be obtained by dividing the barrier clock rate by the ?? rate. Finally, the invention provides an agile barrier capable of communicating data across a serial interface at a variety of data rates and at an approximately fixed interface clock rate.

  • Patent number: 8380420
    Abstract: Precise operation of an accelerator operating member (7) is more difficult to perform in a reversing operation of a vehicle (1) as compared with an advancing operation. Therefore, behavior of the vehicle (1) is not smooth and thus tends to be unnatural. In the reversing operation of the vehicle (1), driving force output from an internal combustion engine (2) is limited in accordance with vehicle acceleration (D). At this time, it is possible to regulate the driving force of the vehicle (1) in conformity to the actual operation of the accelerator operating member (7) by the driver. In addition, limitation of the driving force is not executed in the advancing operation of the vehicle (1). At this time, the vehicle (1) can be driven in a state in which the driving force is comparatively small. Therefore, it is possible to prevent the behavior of the vehicle (1) from being unnatural.

  • Publication number: 20090262912
    Abstract: Distortion caused by a DSL signal can be determined with the DSL signal. The DSL signal and/or the power spectral density (PSD) can be altered to suitably reduce or eliminate the distortion effects, which normally would be reduced by a POTS splitter. As a result of such adjustments to the DSL signal, the POTS band noise is suitably reduced to resolve potential adverse POTS quality issues. In addition, the DSL performance can be improved as well as the undesirable distortion is reduced. Splitterless DSL allows the DSL equipment to be connected to subscriber loops without needing a POTS splitter. This splitterless DSL configuration may be used with conversion equipment utilized to provide indirect DSL service over loaded and/or unloaded loops. In addition, the splitterless DSL configuration also will work with normal DSLAMs.

  • Patent number: 7349536
    Abstract: Uninterrupted digital communications are provided between a central office and a customer premises by using a high-pass or bandpass filter to bypass local loop generation equipment. In many present-day telecommunications installations, local loop generation equipment may be placed in series with a communications path that runs between the central office and the customer premises. This communications path is adapted to convey digital signals as well as voice information and/or other types of baseband communications signals. In order to avoid interference between baseband signals and digital signals, each of these signals is allowed to occupy only a specified portion of the frequency spectrum. When activated, the local loop generation equipment breaks the entire communications path, interrupting voice signals, as well as any digital signals which may be carried thereon.

  • Patent number: 7295569
    Abstract: Selecting a profile for an interface of a network device includes accessing profile sequences, where each profile sequence corresponds to an interface. Each profile sequence includes profiles that provide parameters for communicating data. The following are repeated for a profile sequence for an interface until a link satisfies a sequence criterion or until a last profile of the profile sequence is reached to select a profile for the interface. A current profile is accessed, and a link for the interface is initiated according to the current profile. Whether the link for the interface satisfies the sequence criterion in accordance with the margin set is determined. A next profile of the profile sequence is accessed if the link does not satisfy the sequence criterion in accordance with the margin set, and the current profile is selected if the link satisfies the sequence criterion. Data is communicated according to the selected profile.
