  • Publication number: 20240317960
    Abstract: Polymeric microspheres may be included in polyisocyanurate/polyurethane foam compositions. An exothermic foaming process and/or the application of heat during the foaming process may cause the polymeric microspheres to expand in diameter. The expanded polymeric microspheres may improve the structural properties and/or the insulating properties (e.g., R-value) of the resultant foamed PIR/PUR composition, especially an open-cell structure.

  • Patent number: 7660528
    Abstract: One embodiment of the present invention provides a system for mitigating Raman crosstalk between downstream data and video transmission in an Ethernet passive optical network (EPON), wherein the EPON includes an optical line terminal (OLT) and one or more optical network units (ONU's). During operation, the system transmits a data stream from the OLT to the ONU's on a first wavelength that is substantially at 1490 nm. The system also transmits a video signal stream from the OLT to the ONU's on a second wavelength that is substantially at 1550 nm. The system modifies the bit sequence for the data stream to change the power spectral distribution (PSD) for the data stream, thereby reducing power spectral content in the frequency range where significant Raman crosstalk can occur between data and video signal streams.

  • Publication number: 20080122911
    Abstract: Material-handling systems are described that maximize the stability of materials, such as inks or clear overcoat materials. Some of the material handling systems oxygenate the material as it moves through the material-handling systems, reducing premature polymerization of the material and/or providing a stable viscosity.

  • Patent number: 6778526
    Abstract: A high speed access bus interface for a communications network. The interface allows uni-directional transfer of data packets at a fast path processing rate of about 10 gigabits per second. The interface uses a master port and a slave port in a chip to chip data transfer scheme. The master and slave ports may have one or more than one data channel for transferring data packets. The master port includes a clock signal for synchronizing the transfer from the master port to the slave port. The slave may send an asynchronous signal to the master port in order to initiate the master port to stop or stall the pipeline transfer of data packets until space is made available in the slave port buffer. In addition to the clock synchronization, the interface utilizes an enable signal, a start of packet signal, an end of packet signal, an error signal (if necessary), a last valid byte signal, and a parity bit signal to identify, address, each data packet in the data stream.

  • Patent number: 6360340
    Abstract: A semiconductor memory test system with improved fault data processing and display capabilities. The memory tester includes a lossless data compressor for failure data. Compression allows failure data to be more rapidly transferred to a display device that is part of a work station controlling the memory tester. It also reduces the amount of data that must be stored in the display memory, thereby providing a cost effective way to store data from multiple tests. By allowing data for multiple tests to be stored, the data from a prior test can be used to control the formatting of data for a subsequent test. Such formatting is useful for such things as observing failure mechanisms as the operating temperature or speed of the semiconductor memory under test increases.

  • Patent number: 6317427
    Abstract: A data buffering storage circuit automatically allocates a portion of shared storage area to the direction in which data buffering is required. This scheme allows use of fewer parts on a piece of networking hardware, which in turn lowers the cost, simplifies the design, and uses existing on-board memory in a more efficient manner. In at least one embodiment, a first area is allocated to the buffering of a first port of a network switch, a second memory area is allocated to the buffering of a second port of the network switch, and a third area is shared among the buffering of the first port and the buffering of the second port.

  • Patent number: 6286120
    Abstract: A tester having a fast but flexible pattern generator which is implemented using readily available memories. The tester includes a pattern memory which holds test vectors. The vectors are organized into modules. The order of execution of the modules is selected from a list stored in memory. In the preferred embodiment, memories which operate in burst mode are used to implement the pattern memory. To compensate for the decrease in data rate which occurs when execution switches between modules in the middle of a burst, the memory refresh rate is dynamically altered upon switching between modules.
