  • Publication number: 20040155140
    Abstract: A rewinder method and apparatus. The payout assembly of a rewinder machine comprises a spool having optical fiber wrapped about it, a motor that turns the spool as fiber is unwound from the spool, a first sheave having a surface along which the unwound fiber passes, a load cell in direct contact with the first sheave, and a motion mechanism for producing relative motion between the spool and the first sheave. The load cell senses stress exerted on the first sheave by the fiber as the fiber passes along a surface of the. The load cell produces electrical signals relating to the fleeting angle between the first sheave and the position on the spool from which fiber is being unwound. A controller receives the electrical signals and generates control signals that cause the motion mechanism to produce relative motion between the spool and the first sheave in a direction substantially parallel to an axis of rotation of the spool to reduce the fleeting angle.

  • Publication number: 20040154286
    Abstract: The invention relates to a new method and system for optimizing the efficiency of an automotive catalytic converter by adjusting the engine air/fuel ratio based on estimates of the actual amount of oxidants stored in the catalyst. The oxidant storage capacity of the catalyst is adjusted by controlling engine spark in response to an estimate of a current amount of oxidants stored in the catalyst and an estimate of the total available oxidant storage capacity of the catalyst. To maintain engine speed in spite of adjustments to the engine spark, the engine air mass is also adjusted.

  • Publication number: 20040154743
    Abstract: Process related materials including photoresist and associated residues are removed from a substrate by exposing the substrate at least to one form of ultraviolet radiation-activated reactive gas phase radical to activate reactions between the gas phase radicals and the process related materials. The substrate may be exposed to the activating UV energy. Alternatively, the substrate may be exposed to a first reactive gas phase radical, from a first source, in conjunction with at least one of a selected gas and a second species of gas phase radical from a second source. The first and second source outputs may be combined prior to entering the process chamber or may enter the processing chamber separately. Selective limitation or elimination of substrate exposure to UV radiation is described.

    Abstract: A training go-cart that includes multiple safety features making the cart safe for operation by young children. Each axle of the Wee-Kart has two left tire and two right tires. This double wheel feature adds stability and traction to the cart. To keep potentially dangerous moving parts away from the driver, the engine is placed front of the vehicle and the drive system is housed underneath of the vehicle. The vehicle also includes at least one emergency shut off switch, which is capable of shutting off the motor. A pressure sensitive switch can be provided in the driver's seat so that the motor shuts off whenever the driver gets out of the seat. The emergency shut off switch can also be operated by a radio signal, such as a “kill” signal sent from a remote transmitter held by a parent of the driver.

  • Publication number: 20040155205
    Abstract: A system and method are used to isolate a first gas from a second gas using a third gas. A first chamber includes an element that emits light based on a first gas. A second chamber uses the emitted light to perform a process and includes the second gas. A gaslock that couples the first chamber to the second chamber. A gas source supplies a third gas between the first and the second gas in the gaslock, such that the first gas is isolated from the second gas in the gaslock. The first and third gas can be pumped from the first chamber and separated from one another, such that the first gas can be recycled for reuse to form the emitting light.

  • Patent number: 6772901
    Abstract: A tamper-resistant, tamper-evident composite lid is disclosed for use with containers having a peripheral lip formation around the opening thereof, such as an ice cream container. The closure member comprises integral outer and inner cylindrical ring portions which present at their upper peripheral margin a downwardly stepped annular ledge formation for adhesively receiving a paperboard or other flexible cover panel. The inner ring portion presents a plurality of resiliently deformable teeth extending upwardly and inwardly from its lower peripheral margin configured to lockingly engage with the lip of the container for sealing. The inner ring is circumscribed by a rupturable line of weakness which ruptures upon any attempt to prise off the lid, providing evidence of tampering. The container is legitimately opened by manually tearing away the bottom portion of the inner ring along its line of weakness.

  • Patent number: 6775652
    Abstract: Recognizing a stream of speech received as speech vectors over a lossy communications link includes constructing for a speech recognizer a series of speech vectors from packets received over a lossy packetized transmission link, wherein some of the packets associated with each speech vector are lost or corrupted during transmission. Each constructed speech vector is multi-dimensional and includes associated features. Potentially corrupted features within the speech vector are indicated to the speech recognizer when present. Speech recognition is attempted at the speech recognizer on the speech vectors when corrupted features are present. This recognition may be based only on certain or valid features within each speech vector. Retransmission of a missing or corrupted packet is requested when corrupted values are indicated by the indicating step and when the attempted recognition step fails.

  • Patent number: 6774675
    Abstract: A bus hold circuit of CMOS components that draws no DC current and is over voltage tolerant is described. No leakage current is drawn from the input when the input voltage is greater than the bus hold circuit supply voltage. A feedback inverter is used to s latch the Vin logic in the bus hold circuit. When Vin is low, it turns on a first switch that drives the gate of a PMOS switch low turning it on. The PMOS switch connects the power connection of the feedback inverter to Vcc. The gate remains low, keeping the PMOS switch turned on as Vin increases. The first switch is turned off, but the gate of the PMOS switch remains low, until Vin exceeds Vcc. At that point, a comparator drives the gate of the PMOS to Vin shutting the PMOS switch off. An arbiter circuit selects the higher of Vcc and Vin to bias the N-well of the PMOS switch and other PMOS components in the comparator and arbiter circuit. This biasing ensures that the N-wells are never forward biased, thereby preventing leakage from the Vin.

  • Patent number: 6775693
    Abstract: The invention blends Fiber Channel (“FC”) hardware with networking software to produce a network that allows network data to be transferred via direct memory access (“DMA”) between two application buffers in computers separated by a network. During boot up, the FC network interface card (“NIC”) drivers specify MTUs greater or equal to the segment size to the operating system so that data are not segmented into smaller datagrams during a network data write. During the network write, a first FC NIC sets up the send end of the DMA and sends the network headers of the data to a second FC NIC. The second FC NIC passes the network headers up through the protocol stack. The protocol stack locates and passes the application buffer address to the second FC NIC. The second FC NIC sets up the receive end of the DMA and sends a signal to the first FC NIC to start a buffer-to-buffer DMA transfer of the data.
