Abstract: An adaptive method of providing electrical interconnections for a plurality of feed-through lines each having a respective end extending to at least one substrate surface includes generating an artwork representation for the electrical interconnections using specified feed--through line end positions on the at least one substrate surface. The at least one substrate surface may include a surface of a stack of substrates with at least two substrates having feed-through line ends facing a common direction. Actual positions of the at least two of the feed--through line ends are determined, and a scale factor is estimated using the determined actual positions. Actual positions of others of the feed-through line ends are estimated using the scale factor, and the artwork representation is modified to properly include electrical interconnections to ones of the feed-through line ends which are not in their specified positions. The artwork representation can be converted into a turn point polygon (TPP) format for effective data handling and modification of the artwork representation, and the TPP format can then be can be converted to a rectangular representation. A laser can be controlled in accordance with the rectangular representation of the modified artwork.

IPC: H04B10/2581
Filed: 1996-08-22
Granted: 1999-05-04
Abstract: An apparatus and method provides optical multiple wavelength signals using a single optical broadband source to generate many independent optical wavelength channels. An optical transmitter includes a pulse chirping device which separates the frequency components of periodic optical pulses in the time domain forming separate wavelength channels which are separately modulated by a high-speed broadband optical modulator. A receiver includes a passive splitter to separate the individual wavelength channels. The chirped-pulse transmitter can then be conveniently adjusted to provide optimum overlap of wavelength channels with the modulating channel spectra.

Abstract: An apparatus and method for perforating corrugated plastic pipe from the inside of the pipe to the outside and the pipe produced by the method.  The apparatus has a perforating device attached to an elongated support member.  Perforations are created by advancing pipe over the perforating device or by advancing the perforating device into the interior of the pipe. Where the pipe is advanced over the perforating device, a carriage, holding the pipe, is riding on a track which guides the pipe into engagement or into cutting or perforating proximity with the perforating device.  The perforating device includes a housing holding motors with cutters attached to them.  The cutters cut the inner corrugations or the valleys of the pipe as the pipe is passed over the perforating device. Pipe is perforated by advancing it over a perforating device, and cutting the pipe from the inner pipe surface to the outer pipe surface. The perforated pipe made using this apparatus and method is distinguishable from similar pipe where the preforations are made from the outside of the pipe to the insided of the pipe.

Title: Acquisition and error recovery of audio data carried in a packetized data stream
Inventor: MORONEY PAUL
IPC: H04N19/895
Filed: 1996-11-19
Granted: 1999-10-12
Abstract: Audio data is processed from a packetized data stream carrying digital television information in a succession of fixed length transport packets. Some of the packets contain a presentation time stamp (PTS) indicative of a time for commencing the output of associated audio data. After the audio data stream has been acquired, the detected audio packets are monitored to locate subsequent PTS's for adjusting the timing at which audio data is output, thereby providing proper lip synchronization with associated video. Errors in the audio data are processed in a manner which attempts to maintain synchronization of the audio data stream while masking the errors. In the event that the synchronization condition cannot be maintained, for example in the presence of errors over more than one audio frame, the audio data stream is reacquired while the audio output is concealed. An error condition is signaled to the audio decoder by altering the audio synchronization word associated with the audio frame in which the error has occurred.

Abstract: In the system of the invention the adjunct device is connected to the switching system over two connections. The first connection is a voice channel consisting of an analog line capable of transmitting voice but not call data such as called party number, calling party number or the like. The second connection is a data connection via an Ethernet channel between the switch and adjunct that transmits call data but is incapable of transmitting voice. The call data is logically associated with the voice call at both the adjunct and switching system. As a result, transaction data related to a voice call can be forwarded to an agent station or other terminal when the voice call is transferred from the adjunct to the agent station. This system eliminates the need to recreate the transaction data when a call is transferred while using inexpensive analog connections for the voice call.

Title: Closed loop fluid-handling system for use during drilling of wellbores
Inventor: BRADFIELD DAVID H
IPC: E21B43/34
Filed: 1997-05-05
Granted: 2006-07-11
Abstract: This invention provides a fluid-handling system for use in underbalanced drilling operations. The system includes a first vessel which acts as a four phase separator. The first vessel includes a first stage for separating solids. Oil and gas are separated at a second stage. A pressure sensor provides signals to a pressure controller, which modulates a gas flow valve coupled to the vessel for discharging gas from the first vessel. The pressure controller maintains the pressure in the first vessel at a predetermined value. An oil level sensor placed in the first vessel provides a signal to an oil level controller. The oil level controller modulates an oil flow valve coupled to the vessel to discharge oil from the first vessel into a second vessel. Water is discharged into a third vessel. Water from the third vessel is discharged via a water flow control valve, which is modulated by a level controller as a function of the water level in the third vessel. Any gas in the third vessel is discharged by modulating a gas control valve as a function of the pressure in the third vessel. In an alternative embodiment, a central control unit or circuit is utilized to control the operations of all the flow valves. During operations, a control unit maintains the pressure and the levels of the fluids in such vessels at their respective predetermined values according to programmed instructions. The fluid-handling system also controls the wellbore pressure as a function of downhole-measured parameters and the drilling fluid mix as a function of selected operating parameters.
