US07784041B2 Mechanism for reducing detectable pauses in dynamic output caused by dynamic compilation
A method is disclosed for reducing dynamic pauses during dynamic compilation. Applications running on a system detect the rendering of dynamic output to a user. The dynamic output represents a change in visual or audio data while any application is running. When an application detects such output it notifies the system, which monitors the frequency of the dynamic output. If the frequency of the dynamic output exceeds a threshold, the system informs a compiler on the system to suspend compilation. Compilation normally occurs when an interpreter on the system is instructed to pass processing control to the compiler. One way this occurs is if a method currently being processed by the interpreter has been marked for compilation. Thus, in order to suspend compilation, the compiler ceases to mark methods for compilation so that the interpreter will not be instructed to pass processing control to the compiler.

In this way, there is no runtime overhead to maintain the correctness of the two copies of data. Moreover, the number of lines of the software cache that must be protected from eviction is decreased. This leads to a decrease in the amount of computation cycles required by the cache miss handler when evicting cache lines during cache miss handling.

The TCP/IP session proceeds simultaneous with the telephone call between the agent and the customer.
US07783751B2 Communication system, proxy server, method of controlling same and control program therefor
It is arranged so that the history of access to a web page at a terminal device that does not have a unique IP address can be determined. To achieve this, a proxy server generates identification data of the terminal device upon accepting a request for a web page from the terminal device the first time. A link destination URL included in the web page conforming to the request is changed by the proxy server and a web page in which the URL after the change has been embedded is displayed on the terminal device. If the proxy server is requested for the web page having the URL after the change, the URL is restored by the proxy server to the URL that prevailed before the change and the web server is requested for the web page having the URL that prevailed before the change. Since the URL after the change is one that only the terminal device of the generated identification data can ascertain, the history of access by the terminal device can be determined by storing the URL, which prevailed before the change, of the requested web page in correspondence with the identification data.

US07782940B2 Methods for encoding or decoding in a videoconference system to reduce problems associated with noisy image acquisition
Disclosed herein in one embodiment is an adaptive coding threshold algorithm for a videoconference system which alleviates problems due to the erroneous recoding of stationary areas of images caused by image noise. The algorithm, which is preferably implementable on a videoconference encoder, assesses the coding parameters for a current macroblock and the coding parameters for that same macroblock the last time it was coded. If for both macroblocks the coding was non-intra, with a [0,0] motion vector, and with a low quantization parameter, a determination is made that the current macroblock depicts a stationary image. Accordingly, the algorithm increases the coding threshold (T1) for the blocks within that macroblock, so that it becomes more difficult for those particular blocks to be recoded. This renders the block with stationary content less susceptible to erroneous recoding, while preserving system bandwidth and improving image quality. Additionally, related noise assessment techniques can be employed at the encoder or decoder without the adjustment of the coding threshold T1.

US07782774B2 TCP optimized single rate policer
An extension to the conventional single rate microflow policer that provides dual rate policing with a minimum of extra resource utilization. Using the extended microflow policer, an aggressive TCP flow ramps up to exceed the policer rate, setting a burst drop flag. Once the flow rate exceeds the burst rate, a single packet is dropped and the burst drop flag is cleared. On seeing the single packet drop, the TCP sender is then expected to reduce its rate. Flows that do not back off will eventually exceed a higher, hard drop threshold and experience packet drop. An aggressive TCP rate thus oscillate around the burst rate, efficiently approaching the hard drop rate without exceeding it. The addition of only a single bit flag avoids the cost of a dual-rate policer and the tail drop behavior induced by a single rate policer.

An address information modulation method includes using a first characteristic of a first modulation method and a second characteristic of a second modulation method to modulate address information and/or additional information. Accordingly, a data amount of information, to access a disc, in a predetermined space of the disc is increased, and the modulated information is formed in a form of a wobble signal in a track. Here, the first characteristic of the first modulation method can be physical location information of an MSK-modulated signal, and the second characteristic of the second modulation method can be sign information of a second harmonic wave obtained by an HMW modulation, which synthesizes a cosine function of a basic frequency of a wobble signal with a sine function having a frequency that is a multiple of the basic frequency of the wobble signal. Therefore, where the address information is modulated, a plurality of information bits are loaded on a predetermined number of wobble or carrier signals to increase the amount of the information in the predetermined space, such that a physical length of the information needed in accessing the disc and reading the additional information thereof is shortened. Also, where a defect occurs, the resulting loss can be reduced such that addressing specifications for a small-sized high density disc can be satisfied.

US07782527B1 Multi-stage optical amplifier having photonic-crystal-rod waveguides and non-photonic-crystal optical fiber interconnects and associated method
A method and apparatus use a photonic-crystal fiber having a very large core while maintaining a single transverse mode. In some fiber lasers and amplifiers having large cores problems exist related to energy being generated at multiple-modes (i.e., polygamy), and of mode hopping (i.e., promiscuity) due to limited control of energy levels and fluctuations. The problems of multiple-modes and mode hopping result from the use of large-diameter waveguides, and are addressed by the invention. This is especially true in lasers using large amounts of energy (i.e., lasers in the one-megawatt or more range). By using multiple small waveguides in parallel, large amounts of energy can be passed through a laser, but with better control such that the aforementioned problems can be reduced. An additional advantage is that the polarization of the light can be maintained better than by using a single fiber core.
