Abstract: In an optical or magneto-optical recording and/or reproducing apparatus, an apparatus for locating a pre-designated one of a large number of tracks on the recording medium (1) by a light beam (9) at a high speed during signal recording, reproduction or erasure. The light beam irradiated on the recording medium is swept in the direction of traversing the tracks, the reflected (10) light of the light beam from the recording medium is detected by a photodetector (11), and a predesignated one of the tracks is retrieved on the basis of the results of detection of the reflected light. The sweeping movement of the light beam is controlled by feedback control of the track traverse velocity of the light beam prevailing until the beam gets to the predesignated track. The velocity detection system for detecting the track traverse velocity is provided with a pulse generator for generating, on the basis of the detection signal by the photodetector, an m number of pulses per on n number of tracks traversed by the light beam until it gets to the predesignated track, a counter for measuring the period of the generated pulse and a velocity computing circuit for computing, on the basis of the count value by said counter, the track traverse velocity of the light beam prevailing until the beam gets to the predesignated track.

Abstract: The present invention provides a method and means for maintaining metal parts in fixed relation to each other throughout a brazing cycle. The fixed relation is maintained by supporting the parts on concentric support rings made of the same alloy as the parts. The support rings lie within backup rings which exhibit high creep strength at the temperature necessary to braze the parts. The backup rings are slideably supported on a base, and a cover is provided which cooperates with the base to prevent furnace contaminants from contacting the parts during the brazing cycle.

Abstract: Double talk is rapidly detected for effectively preventing degradation of echo cancellation in a long distance telephone communications system. An echo estimator includes a transversal filter and receives an incoming signal and tap coefficients, and then adaptively produces an estimated echo signal. A subtractor (22) is adapted to subtract the estimated echo signal from an echo signal applied thereto, and outputting an error signal indicating residual. echo. A tap coefficient updating circuit (24) is coupled to receive the error signal and the incoming signal and the tap coefficients, and renews the tap coefficients. A double talk detector (52) is coupled to receive the error signal and the incoming signal and the echo signal. The double talk detector (52) issues a double talk detection signal in the event that a cross-correlation value between the incoming and echo signals is less than a first predetermined level while an estimated echo cancellation is larger than a second predetermined level.

Abstract: A predictive dialing system having a computer (10) connected to a telephone switch (17) stores a group of call records in its internal storage (12). Each call record contains a group of input parameters, including the date, the time, and one or more workload factors. Workload factors can indicate the number of pending calls, the number of available operators, the average idle time, the connection delay, the completion rate, and the nuisance call rate, among other things. In the preferred embodiment, each call record also contains a dial action, which indicates whether a call was initiated or not. These call records are analyzed by a neural network (40) to determine a relationship between the input parameters and the dial action stored in each call record. This analysis is done as part of the training process for the neural network. After this relationship is determined, the computer system sends a current group of input parameters to the neural network, and, based on the analysis of the previous call records, the neural network determines whether a call should be initiated or not. The neural network bases its decision on the complex relationship it has learned from its training data -- perhaps several thousand call records spanning several days, months, or even years. The neural network is able to automatically adjust -- in a look ahead, proactive manner -- for slow and fast periods of the day, week, month, and year.

Abstract: In an echo canceller with a residual echo limiter (NLP) at the transmission path output (SWA), its output signal is compared with a residual echo limiter threshold which is barely above the level of a residual echo to be expected. If the voice level of a close subscriber is below this threshold, the residual echo limiter (NLP) effects an interruption at the transmission path output (SWA), if it is above the threshold, the interruption is cancelled. However, the remote subscriber perceives a temporary lack of ambient noise at the local subscriber as disturbing. This lack is eliminated by the fact that the output signal is not interrupted but limited to the noise level. This is done by a change-over switch (U1) which connects the output (SA) of a subtracter (S) to the transmission path output (SWA), either directly or via an amplitude limiter (B). The limiting is effected by the content of a memory (SP), the memory input of which is connected to the output (SA) of the subtracter (S) via a filter circuit (SI) during pauses in the conversation and is connected to the output of the memory (SP) during a conversation. <IMAGE>

Abstract: Methods for recovering a LWD or MWD data signal in the presence of mud pump noise are provided and generally comprise calibrating the drilling mud pressure as a function of the mud pump piston position, and then tracking the piston position during transmission of the LWD or MWD data signal and using the calibration information to subtract out the mud pump noise. Calibration is accomplished in the absence of the LWD or MWD data signal to provide a correlation between mud pump piston position and the drilling mud pressure. Then, when the LWD or MWD data signal is being generated, the mud pump piston position is tracked such that the pressure due to the pump can be subtracted and the LWD or MWD signal recovered. Where a plurality of mud pumps are being utilized, calibration is accomplished by running the mud pumps together in the absence of the LWD or MWD data signal, and processing the received mud pressure signals in the Fourier domain to allocate respective portions of the mud pressure signals to respective mud pumps such that each mud pump is provided with a signature as a function of its own piston position. With the piston position of each mud pump being tracked, the sum of the mud pressure signals generated by the mud pumps based on their piston positions is subtracted from the total received signal to recover the LWD or MWD signal.
