Abstract: A dimensionally stable carpet underlay manufactured from needle-punched fibers arranged to form a non-woven felt fabric, to which an acrylic latex pressure sensitive adhesive is applied by a dipping process that coats the surfaces of the fibers and fills the interstices between the fibers. The acrylic adhesive is applied to the felt substrate in a dip and squeeze operation, which passes a felt web through a trough of adhesive and then through an excess adhesive removal station, after which, a protective releasable polymer film is applied to the exposed adhesive surfaces prior to curing step. The acrylic adhesive is selected to exhibit sufficient tackiness to secure the carpet in place, but allowing for easy removal and not leaving a residue after removal of the carpet from the underlay or removal of the underlay from the underlying supporting floor surface.

Abstract: A process and interface for interconnection of multiprocessor modules by point-to-point serial-to-parallel links. Data processing or data communication modules (A and B) are interconnected by means of high-speed point-to-point serial links conveying multiplexed information organized into frames comprising a start-of-frame recognition pattern. The process, on transmission and on reception, performs an analog synchronization of the basic clocks of the modules to a reference clock generated by one of the modules designated as a reference module, called the master module, the other modules being called slave modules, and a digital synchronization of the start-of-frame of each slave module to the start-of-frame sent by the master module.

The agent server comprises autonomous agents (5) that communicate via notifications, a storage layer and an agent machine comprising an execution engine, a communication channel and two message queues for the notifications, a local queue (mqIn) and an external queue (mqOut). The execution engine takes a notification in the local queue, determines and loads the corresponding agent for each notification, has the agent react to the notification, which agent can then change its status and/or send notifications to the communication channel (2), which stores them in the local queue if they are addressed to a local agent and in the external queue if they are addressed to an agent of another server.

Abstract: The lock architecture for a computer system comprises several processors (10, 11, 12, 13) such that each processor (10) requesting a resource of the system takes control of said resource if a first lock state indicates that said resource is free. The requesting processor is placed on active standby if a second lock state indicates that said resource is busy. A lock includes a first and second lock state. The first lock state corresponds to a null value, and the second lock state corresponds to a non-null value.

Abstract: The present invention provides for a system for operating a communication device (20) for reception of scheduled intermittent information messages (22) with a dual mode timer (70) that extends battery life. A controller (50) schedules the timer (70) to power down all idle components of the device (20) between message receptions in a power saving sleep mode to conserve battery power. During active mode when the device is fully active in reception of messages, the timer (70) uses a reference oscillator (90) with a relatively high frequency to support digital processing by the receiver (26). During sleep mode when only the timer is powered on, a much lower frequency sleep oscillator (96) is used to maintain the lowest possible level of power consumption within the timer itself. The timer (70) has provision for automatic temperature calibration to compensate for timing inaccuracies inherent to the low-power low-frequency crystal oscillator (96) used for the sleep mode.

Abstract: On a machine with non-uniform memory access distributed over several modules, each module includes one or more processors for executing tasks on a virtual or physical addressing space by effective addresses generating logical page numbers to which it is possible to make physical page numbers correspond in the memory by a correlation tale. The generation of a logical page number causes a first-level page-fault type exception when the logical page number is absent from the correlation table. The method includes a step for activating a function (Trace), following each first-level page-fault type exception, a trace function, which records the value of the effective address that has generated the logical page number that has caused the exception, the date when the exception is caused, an identifier of the task using the effective address, an identifier of the processor executing the task and the physical page number corresponding to the logical page number that has caused the exception.

Abstract: The present invention provides for a system and method for improvement of radio transmitter and receiver frequency accuracy for a local radio communication unit that communicates digital data with a remote communication unit. In the local unit the received radio signal is down-converted, and converted to complex baseband digital samples by an analog-to-digital converter. A downlink digital phase rotator applies a fine frequency shift to the samples in accordance with a receiver frequency offset command. The resultant baseband signal is used by the data demodulator and by a receiver frequency error estimator to obtain receiver frequency errors. A data modulator generates baseband complex samples which are shifted in carrier frequency by an integrated uplink digital phase rotator in accordance with a transmitter frequency offset command. The modulated samples are then converted by a digital-to-analog converter and upconverted in frequency for radio transmission to the remote unit.

Abstract: The invention relates to an architecture for management of vital data in a multi-module digital data processing machine (1) and the process for its implementation. Each module (M1 through Mn) comprises a physical nonvolatile memory (NVM1 through NVMn) in which vital data is stored. A first area (G1 through Gx) stores global vital data obtained by copying and associated with the operation of the machine (1). A second area (L1 through Lx) stores local vital data associated with the operation of the module (M1 through Mn). A virtual nonvolatile memory in two parts, global memory and local memory divided into windows, makes it possible, under the control of an extension of the operating system, to address the physical nonvolatile memories (NVM1 through NVMn). The windows of a defective module (M1 through Mn) are not visible. At the startup, a specific firmware determines the state of the modules (M1 through Mn).
