  • Patent number: 5634102
    Abstract: A method, in a digital computer having a display screen, for executing an application program in a backdrop mode that makes the application program non-removable from the display screen. The method includes the steps of designating the application program for execution in the backdrop mode and executing the application program. Further, the method includes the step of intercepting, using substitute subroutines external to the application program, selected data destined for the application program. The interception advantageously prevents the application program from responding to the selected data in a manner normally expected of the application program if the application program executes in a non-backdrop mode. The selected data that is intercepted includes data for causing the application program to quit execution.

  • Patent number: 5630136
    Abstract: An improved technique for serializing access to multithreading unsafe resources is described. A baton manager is used to manage the serializing of accesses to a multithreading unsafe resource. For a thread to access the multithreading unsafe resource, the thread must first obtain a baton from the baton manager. Then, once the thread has finished accessing the multithreading unsafe resource, the thread releases the baton to the baton manager. Hence, by using the baton manager to manage the baton, accesses to multithreading unsafe resources are serialized while program crashes or deadlocks are minimized. The multithreading unsafe resource will typically have a plurality of baton objects associated therewith. The baton objects are objects of object-oriented programming. The baton manager will permit at most one of the baton objects for a given multithreading unsafe resource to own the baton at a time.

  • Patent number: 5627863
    Abstract: A discrete multitone modulation transmission system is described in which frame synchronization is monitored at the receiver by correlating frequency domain complex amplitudes of a synchronizing frame with a stored synchronizing pattern. If the correlation result falls below a threshold, indicating a loss of frame synchronization, a plurality of correlations are performed, in each case using the stored complex amplitudes of the synchronizing frame multiplied by a respective complex value representing a respective complex derotation corresponding to a respective possible time shift of the synchronizing frame. The best correlation result, if it exceeds another threshold, indicates a time shift for restoring frame synchronization, this being possible before the next synchronizing frame is received.

  • Patent number: 5624304
    Abstract: A technique for mounting polishing pads to a platen in chemi-mechanical semiconductor wafer polishing apparatus is disclosed. A lower pad is mounted to the platen, and is trimmed to the size of the platen. An upper pad is mounted to the lower pad, and is sized so that an extreme outer edge portion of the upper pad extends beyond the trimmed outer edge of the lower pad. The outer edge portion of the upper pad is deformed downwardly, towards the lower pad. In this manner, polishing slurry is diverted from the pad-to-pad interface. Additionally, an integral annular lip can be formed on the front face of the upper pad, creating a reservoir for slurry to be retained on the face of the upper pad for enhancing residence time of the polishing slurry prior to the slurry washing over the face of the upper pad.

  • Patent number: 5625814
    Abstract: A method and apparatus for processing natural language and deducing meaning from a natural language input characterized by the steps of (a) receiving an ordered string of word objects having a natural language meaning, (b) selecting a word window length, and (c) successively moving the word window along the ordered string and analyzing the meaning of a substring of word objects that fall within the word window. The substring is removed from the ordered string if the substring has a recognized meaning, until all substrings of the ordered string that fit within the window have been analyzed. In a step (d), the word window length is reduced and step (c) is repeated until only an unrecognized residual of the ordered string remains. The meaning of the substring is analyzed by mapping the substring against a database using one or more mapping routines.

  • Patent number: 5625651
    Abstract: A bi-directional data transmission system that facilitates communications between a central unit and a plurality of remote units using a frame based discrete multi-tone (DMT) transmission scheme is disclosed. The discrete multi-tone data transmission system has a multiplicity of discrete subchannels including an overhead bus. In a method aspect of the invention, frames transmitted from the plurality of remote units are synchronized at the central unit. When a selected remote desires to initiate communications, it loop times it own clock to the clock of the central unit and transmits a remote initiated synchronization signal to the central unit over a dedicated overhead subchannel in the overhead bus. The central unit responds with a centrally initiated synchronization signal that contains information indicative of a frame boundary phase shift required to synchronize the selected first remote unit with other remote units that are currently communicating with the central unit.

  • Patent number: 5623513
    Abstract: A transmission system includes transmit and receive paths coupled via a hybrid circuit to a bidirectional transmission path. The transmit path includes a digital-to-analog converter (DAC) having a given range and precision. The transmit path signal is limited and truncated to this range and precision before the DAC. In one arrangement including an echo canceller coupled between the transmit and receive paths, a difference of the transmit path signal before and after limiting and truncation is used to produce an estimated echo response which is subtracted from the receive path signal. In another arrangement, all of the inputs to the echo canceller are derived from the transmit path after the limiting and truncation. Instead, or in addition, the amplitudes of transmit path signal samples can be shaped in conjunction with the limiting. The system can in particular be an ADSL transmission system using multicarrier modulation.
