The method includes sending a message including PUSH contents to a terminal, receiving a redirection request from the terminal and sending the message according to the redirection request. A server and a terminal or implementing call directions are also provided. When one of the terminals of a subscriber receives a service not supported by the terminal or through the configuration of the subscriber, messages sent from the server are permanently or temporally transferred to other terminals.

摘要： A protection circuit for a multiple output switching mode power converter protects against an over-current or short circuit failure condition. The protection circuit activates the soft-start circuit of the PWM control circuit upon detection of the over-current or short circuit condition. The soft-start circuit then shuts off operation of the power converter and restarts the power converter after a period of time defined by the soft-start circuit. The protection circuit is effective with any type of power converter topology (e.g., buck, boost, flyback, and forward converter), isolated or non-isolated, having dual or multiple outputs.

摘要： A receiver, comprising an adaptive filter, performs blind equalization using a modified form of the constant modulus algorithm (CMA). This modified form of CMA is referred to as symbol CMA (SCMA). SCMA utilizes both the constant R and the sliced symbols, Ân, in performing blind equalization. The constant R is statistically created to the sliced symbols, Ân. The adaptive filter is a two-filter structure. The SCMA blind equalization technique reduces the rate of occurrence of a diagonal solution.

摘要： The preferred embodiment of the present invention provides a method and apparatus for dealing with scheduling latency in high-speed modems (100) implemented on host processors (101). With the present invention, high scheduling latency of the host operating system (135) is tolerated without incurring large end-to-end transmission delay. In addition, time alignment between downstream and upstream signals (175, 180) is achieved even though the scheduling delay may be large and varying.

摘要： In a chain of linear time-invariant operations (401), all bias introduced between operations collectively produce a total deterministic error at the final output of the chain of operations (401). In the present invention, truncation is used in place of rounding after each operation by simply not rounding in software. Recognizing that all the bias introduced by replacing rounding with truncation results in a single deterministic error at the final output, in the present invention the total bias (403) is predetermined and subtracted from each data sample of the final output sequence.

摘要： During operation a transmitter and receiver of a central site termination unit (TU-C) (101) are driven by a sample clock derived from a network clock source (103). A remote termination unit (TU-R) (102) operates with a free running sampling clock and acquires and tracks the network clock (103) from a downstream signal (104). The regenerated network clock is then used to drive both the receiver (107) and the transmitter (108) of the TU-R (102). In particular, the transmit samples are generated on a block by block basis using fast algorithms. To avoid glitches during data transmission caused by block processing, the data sample at the boundary of blocks of data is replaced by an interpolated value. In particular, a first order approximation to the correct value of the boundary sample is made, and the first order approximation is substituted in place of the boundary data sample of the block.

摘要： A graphical user interface for a computer program enables a user to define a model representing a predefined ideal pattern of objects, the model being useful in analyzing an image of an actual pattern of discrete objects with respect to the model. In the interface, a fragment of the ideal pattern of objects is displayed, the displayed fragment including a graphical indicator of a key distance between objects in the fragment. A device which is visually associated in the fragment with the indicator enables the user to specify a value for the distance. The interface also includes a displayed image representing the pattern of objects, and an interactive device that enables a user to turn on or turn off an object in the image as an indication of its inclusion or exclusion in the pattern.
