Abstract: A pipe handling apparatus, for handling drill tubes on a drilling platform, has an upper guide member comprising a retention head mounted on an arm. The arm can extend telescopically so as to position it to allow the retention head to engage a drill tube for placement in and removal from a rack.

Abstract: The current invention is intended to render artifacts, which are introduced by changes in coefficients in an FIR filter, inaudible by applying a window to the filtered signal that results in the output of the filter (e.g. FIR filter), in which the coefficients are being changed, supplying little or none of the total output while the output of the filter, in which the coefficients are stable, supplies most or all of the total output.

Abstract: Hearing aid systems where a data streaming device streams data to a hearing aid and methods of maintaining synchronization when converting a sampling rate are disclosed. A hearing system comprises a hearing aid, a sampling rate converter, a buffer, an RDWiff signal, and a control circuit. The hearing aid receives data from a data transmission device, and the data received has a first sampling rate. The sampling rate converter is in the hearing aid and converts the sampling rate of the received data to a sampling rate suitable for use by digital signal processing circuitry in the hearing aid. The buffer receives data from the sampling rate converter. The RWDiff signal indicates the difference between the rate at which data is read from and written to the buffer. The control circuit compares the RWDiff signal to a predetermined RWIdeal quantity and generates an adjustment signal.

Abstract: In devices using the present invention, audible artifacts may be reduced or eliminated by designing the system such that the sliding bias level is fed back to an output limiter so that a single algorithm manages all saturation artifacts. In embodiments of the invention, this feedback loop will eliminate the need for a second output limiter.
