  • Publication number: 20230245862
    Abstract: A gas delivery system for substrate processing tool includes a first gas box configured to supply a first gas mixture including one or more gases selected from a first set of N gases to a first substrate processing chamber, where N is an integer greater than one. A second gas box is configured to selectively supply a second gas mixture including one or more gases selected from a second set of M gases to a second substrate processing chamber, where M is an integer greater than one. A third gas box is configured to supply a third gas to the first substrate processing chamber at a first concentration and to supply the third gas to the second substrate processing chamber at a second concentration. The third gas is incompatible with one or more gases in the first set of N gases and with one or more gas in the second set of M gases.

  • Publication number: 20050218229
    Abstract: A system for verifying the authenticity of data contained in a magnetic medium using the remanent noise characteristics of the magnetic medium. In one embodiment, the invention includes a sensing unit configured to generate a signal indicative of the sensed magnetic field and an amplifier. The amplifier is in communication with the sensing unit, is configured to amplify signals having amplitudes less than a threshold by at least a first factor and configured to amplify signals having amplitudes greater than the threshold by at most a second factor. The first factor is greater than the second factor.

  • Publication number: 20050167496
    Abstract: A system for verifying the authenticity of data contained in a magnetic medium using the remanent noise characteristics of the magnetic medium. One embodiment of the invention includes an over-sampled modulator and at least one channel in communication with an output of the over-sampled modulator. The at least one channel is configured to filter the output of the over-sampled modulator and the at least one channel is configured to vary the bandwidth of the filter applied to the output of the over-sampled modulator in response to variations in the bandwidth of the signal generated by the sensing unit.

  • Publication number: 20050136211
    Abstract: A light shielding enclosure has a pair of teremp from a plurality of substrates with a non-woven flocked pile fiber bonded to a plurality of substrates that in turn are then bonded to a shell plate that forms the tubular geometry of the resultant patrone for housing photographic film. The resultant uniform flocked and random pile structure of the properly dyed teremp pile provides a distinct structural light shielding member by this invention. The said teremps in a continuous length along the resulting formed film exit slot along the longitudinal direction maintain a contact at that location member. The continuous length teremps are bonded to the opposite side edges. The non-woven flocked pile teremp has more uniform pile height and greatly reduced loose fibers and long fibers.

  • Publication number: 20050133143
    Abstract: This invention defines a method of making an enclosure for an environmentally sensitive product. The enclosure has a body portion, a support member for the product, and an ingress/egress slot formed in the body portion. A pair of teremp from a plurality of substrates with a non-woven flocked pile fiber is bonded to a plurality of substrates that in turn are then bonded to a shell plate that forms the tubular geometry of the resultant patrone for housing environmentally sensitive product, such as photographic film. The resultant uniform flocked and random pile structure of the properly dyed teremp pile provides a distinct structural light shielding member by this invention. The teremps in a continuous length along the resulting formed film ingress/egress slot along the longitudinal direction maintain a contact at that location member. The continuous length teremps are bonded to the opposite side edges.

  • Patent number: 6430436
    Abstract: A heart rate monitor for use with road bikes and other exercise equipment to calculate the user's heart rate while exercising. The monitor includes only two, first and second, electrodes and a signal processor mounted on the handle bars in a position that contacts the user when the bike is in normal use. The first electrode is disposed at a first location on the handle bars for contacting the user and for sensing the user's heart rate. The first electrode produces a first sensed signal representative of the user's heart rate. The second electrode is disposed at a second location on the handle bars for contacting the user and for sensing the user's heart rate. The second electrode produces a second sensed signal representative of the user's heart rate. The signal processor produces a difference signal indicative of a difference between the first and second sensed signals.
