Inventor: WRIGHT STEPHEN J
IPC: B04B13/00
Filed: 1997-07-25
Abstract: An automated centrifuge includes a weighing station to weigh sample holding racks which arrive at the centrifuge and a rack handling robot to transfer the weighed racks to and from the centrifuge. A controller, which operates the rack handling robot, employs a novel balance method to have the rack handling robot load the sample holding racks in the centrifuge to obtain a best balance arrangement of the sample holding racks.  If the balance method determines that the best balance arrangement will exceed one or more predefined balance thresholds, appropriate remedial action is taken by substituting a selected balance rack for a loaded sample holding rack.

Title: Intelligent acoustic systems peripheral
Inventor: WEISE WAYNE ALLEN
IPC: H04M1/60
Filed: 1997-08-18
Abstract: A personal computer (PC) incorporates a speaker/microphone peripheral, which includes a digital-signal-processor (DSP) based acoustic echo canceler and supports a plurality of modes of operation. One mode is a video/telecommunications mode. In this mode, the acoustic echo canceler is enabled and the speaker/microphone peripheral provides a monaural dual speaker and microphone for use in video, internet telephony, etc., communications. Another mode of operation is a multi-media, or wide-band stereo, mode. In this multi-media mode, the acoustic echo canceler is disabled and the stereo loudspeakers provides high fidelity stereo output signals. In addition, in this latter arrangement an optional sub-woofer may be additionally coupled to the stereo loudspeakers. The speaker/microphone peripheral switches between the operating modes by detecting a predefined sequence of dual-tone-multi-frequency (DTMF) digits. The DTMF sequences are played from wave-type files stored on the PC.

Abstract: A system has been invented for producing a final earth model of part of an earthformation having N (one or more) layers, the method including, in one aspect, generating an initial earth model based on raw data produced by a wellbore logging tool at a location in a borehole through the earth, performing 2-D forward modeling on the initial earth model to produce an interim earth model that includes a set of synthetic tool responses data for the wellbore logging tool, comparing the synthetic tool response data to the raw data to determine whether there is misfit between them; if misfit between the synthetic tool response data and the raw data is acceptable, saving and storing the interim earth model as the final earth model; if misfit between the synthetic tool response data and the raw data is unacceptable, performing 1-D forward modeling N times on theinterim earth model, producing a secondary earth model; performing 1-D inversion on the secondary earth model; and either saving the secondary earth model as the final earth model or re-subjecting the secondary earth model to 2-D forward modeling and subsequent misfit comparison. In one aspect the data is overcorrected following the N times 1-D forward modeling step. In one aspect the N times 1-D forward modeling step is accomplished by using a look-up table of stored values for synthetic tool responses. In one aspect the N time 1-D inversion step is accomplished by using such a look-uptable.

Title: Method and apparatus for removing toner waste from a toner sump
Inventor: URCIUOLI STEPHEN C
IPC: G03G21/10
Filed: 1997-11-27
Abstract: The present invention is a method and apparatus for vacuuming toner waste from a toner sump in a xerographic printing machine. A xerographic module in the machine contains a photoconductor, charging devices, a cleaning unit and the toner sump.  When the toner sump approaches a full condition, the toner waste must be removed in order to prevent failure of the xerographic module seals. This is accomplished by removing the xerographic module from the machine, opening a sealed toner sump port and attaching a vacuum source to the toner sump port so that the toner waste can be removed with the vacuum source. A disposal adaptor tool sealingly engages the vacuum source to the toner sump at the toner sump port, allowing the toner to removed in a clean glove environment. Once the toner waste is removed from the toner sump, a new toner seal is placed over the toner sump port and the xerographic module is returned to the machine for further use.
