Capacitive multidrop bus compensation
The signal integrity of a high speed heavily loaded multidrop memory bus is often degraded due the numerous impedance mismatches. The impedance mismatches causes the bus to exhibit a nonlinear frequency response, which diminishes signal integrity and limits the bandwidth of the bus. A compensating element, such as a capacitor which ties the bus to a reference plane (e.g., a ground potential), or an inductor wired in series with the bus, is located approximately midway between the memory controller and the memory slots. The use of the compensating element equalizes signal amplitudes and minimizes phase errors of signals in an interested frequency range and diminishes the amplitudes of high frequency signals which exhibit high degrees of phase error. The resulting bus structure has increased desirable harmonic content with low phase error, thereby permitting the bus to exhibit better rise time performance and permitting a higher data transfer rate. |

Reducing connection time for mass storage class peripheral by internally prefetching file data into local cache in response to connection to host
Techniques for reducing mount time for a peripheral device connected to an external host device are presented. In some implementations, when a connection is detected, file system data is pre-fetched before a request for such data is sent by the external host device. This allows faster access to the file system data used for initiating read/write communications. In other implementations, in response to a data access command from the external host device, a reply message is delayed from the peripheral device to prevent data access command failures. This delayed response prevents the external host device from pausing before attempting subsequent communication requests. |

Method for determining metrics of a content delivery and global traffic management network
A method for determining metrics of a content delivery and global traffic management network provides service metric probes that determine the service availability and metric measurements of types of services provided by a content delivery machine. Latency probes are also provided for determining the latency of various servers within a network. Service metric probes consult a configuration file containing each DNS name in its area and the set of services. Each server in the network has a metric test associated with each service supported by the server which the service metric probes periodically performs metric tests on and records the metric test results which are periodically sent to all of the DNS servers in the network. DNS servers use the test result updates to determine the best server to return for a given DNS name. The latency probe calculates the latency from its location to a client's location using the round trip time for sending a packet to the client to obtain the latency value for that client. The latency probe updates the DNS servers with the clients' latency data. The DNS server uses the latency test data updates to determine the closest server to a client. |

Techniques to control power by controlling aggregate traffic in a channel
Particular embodiments provide techniques for controlling power in a channel. The power being consumed in a channel may not always be fully used. For example, bursty or Aloha traffic may limit the power being used to transmit data in a channel. Thus, particular embodiments allow transceivers to increase the power used to transmit data in a channel. For example, many transceivers may be allowed to send data in a channel. If all transceivers were transmitting at once at an increased power level, the aggregate power level may be exceeded for the channel. All the transceivers may be allotted a fixed percentage of the aggregate power so as to guarantee not exceeding the power limit. However, not all transceivers may be using their allotted power at the same time. Thus, when the allotted aggregate power in the channel is not fully utilized, a transceiver may increase its traffic beyond its normal portion. For example, the transceiver may use a power-demanding high order modulation scheme to send data. |

Method for run-length encoding of a bitmap data stream
Subtitling aims at the presentation of text information and graphical data, encoded as pixel bitmaps. The size of subtitle bitmaps may exceed video frame dimensions, so that only portions are displayed at a time.

Mechanisms for reducing a size of a color bitmap
In remote control systems (as in many other circumstances) the color representation of a bitmap is one of the heaviest factor in term of storage occupation and speed of transmission. Often, only a limited number of colors is actually used by a bitmap, so that the bit pattern of the single pixels is bigger than what is really needed to represent all the possible different colors.With the present invention, in case the number of colors does not exceed a predetermined thresholds, a palette table containing all the colors used in the bitmap is created. The pixel representations in the bitmap are then replaced by a pointer to the corresponding entry in the palette table. This allows to reduce the total size of the bitmap. The reduced bitmap is then transmitted together with the associated palette table. The receiving computer (the controller in a remote control system) is able to rebuild the original bitmap with the help of the palette table. |

Method of boresight correlation of imager video to reference video
The present invention provides for simple and streamlined boresight correlation of FLIR-to-missile video. Boresight correlation is performed with un-NUCed missile video, which allows boresight correlation and NUC to be performed simultaneously thereby reducing the time required to acquire a target and fire the missile. The current approach uses the motion of the missile seeker for NUCing to produce spatial gradient filtering in the missile image by differencing images as the seeker moves. This compensates DC non-uniformities in the image. A FLIR image is processed with a matching displace and subtract spatial filter constructed based on the tracked scene motion. The FLIR image is resampled to match the missile image resolution, and the two images are preprocessed and correlated using conventional methods. Improved NUC is provided by cross-referencing multiple measurements of each area of the scene as viewed by different pixels in the imager. This approach is based on the simple yet novel premise that every pixel in the array that looks at the same thing should see the same thing. As a result, the NUC terms adapt to non-uniformities in the imager and not the scene. |

Method of broadcasting multimedia content via distribution network
The invention proposes to divide a content to be transmitted via a network into a set of slices and to generate a set of files from this set of slices. The slices (or the files) are encrypted before downloading in such a way that the client cannot use the slice (or the file) before having acquired the associated decryption key. The invention thereby allows protecting a downloaded content on a slice-by-slice basis (or on a file-by-file basis) rather than protecting a downloaded content as a whole. The transmission (in download mode) between the server and the client is ruled by the HTTP protocol that is accepted by all firewalls and NAT. Consequently, the transmitted content is accessible for any client device that has access to the Web without restriction. Advantageously, the slices can be decoded independently of each other. |

Device, system and method for fast secure message encryption without key distribution
One party sends a securely encrypted message to a second party. Each party chooses a secret message key for the message, which is never shared with or transmitted to any other party. The message is sent by means of three encrypted messages. The first encrypted message is sent from the sender to the receiver, and is encrypted by the sender's key. The second encrypted message is sent from the receiver back to the sender, and is encrypted by both the sender's key and then by the receiver's key. The third encrypted message is sent from the sender back to the receiver, and is encrypted by only the receiver's key following removal of the sender's key. Finally, the receiver decrypts the third message. The messages are sent in blocks. Encryption consists of multiplying each block of the message by square matrices of the same size as the block, and decryption consists of multiplying by the inverse matrices. The key matrices are taken from one or more large commutative families of matrices. This commutativity allows the sender's keys to be removed even though the message block has been encrypted by the sender's key first and then the receiver's key. Two primary embodiments of the invention are disclosed, using one-sided and two-sided matrix multiplication, respectively. |

Arrangement for managing voice over IP (VoIP) telephone calls, especially unsolicited or unwanted calls
Trust ratings are embedded in certificates of calling devices in a Voice over Internet Protocol (VoIP) communications system. A method of managing trust ratings involves automatically accumulating complaints concerning VoIP calls initiated from calling devices, and comparing respective quantities of accumulated complaints associated with each calling device. When a quantity of accumulated complaints associated with a given calling device exceeds a given threshold, a trust rating of the given calling device is reduced. In subsequent VoIP calls the given calling device attempts to place, the reduced trust rating is included in the call request so that the subsequent calls are subject to more austere call screening operations than calls having the unreduced trust rating. Call recipients thus affect the calling device's trust rating simply by entering complaints associated with received calls. The method effectively combats spam over Internet telephony (SPIT) through participation of called parties. |

When the RS transitions to a transmission mode, it determines whether to XOR-operate or mask the stored data. If the stored data can be masked, the RS XOR-operates the stored data and sends the masked data to the BS and the MS. |

Adaptive topology discovery in communication networks
A topology discovery process is used to discover all of the links in an ad hoc network and thereby ascertain the topology of the entire network. One of the nodes of the network, referred to as the coordinator, receives the topology information which can then be used to, for example, distribute a routing table to each other node of the network. The process has a Diffusion phase in which a k-resilient mesh, k>1, is created by propagating a topology request message through the network. Through this process, the nodes obtain information from which they are able to discern their local neighbor information. In a subsequent, Gathering phase, the local neighbor information is reported upstream from a node to its parents in the mesh and thence to the parents' parents and so forth back to the coordinator. The robustness of the Diffusion phase is enhanced by allowing a node to have more than one parent as well as by a number of techniques, including use of a so-called diffusion acknowledgement message. The robustness of the Gathering phase is enhanced by a number of techniques including the use of timeouts that ensure that a node will report its neighbor information upstream even if it never receives neighbor information from one or more downstream neighbors and the use of a panic mode that enhances the probability that a node will get its neighbor information, and its descendents' neighbor information, reported upstream even if that node has lost connectivity with all of its parents. |
