Abstract: A method for speech synthesis using prosody capture and transfer includes receiving a first speech in a target prosody and receiving a second speech in a target voice; extracting prosodic features from a first speech segment in the target prosody; generating a synthetic speech segment in the target voice with the target prosody based on transferring the prosodic features from the first speech segment per phoneme to a second speech segment.

Abstract: A fluoroscopic imager for observing a living creature with reduced x-ray dosage uses a video monitor for displaying frames of image samples received during respective ones of frame scan intervals that regularly and successively occur at a display frame rate sufficiently high that brightness flicker is acceptably low to a human observer; an x-ray source that can be gated on for intervals not as long as a display frame; and a fluoroscopic camera, including a raster-scanning video camera and x-ray-to-light conversion apparatus with persistence not appreciably longer than a display frame and frame-filling apparatus. Especially during purely diagnostic procedures, the frame-filling apparatus generates a continuous succession of frames of image samples at the display frame rate by interpolating between successively grabbed frames of image samples.

Abstract: Apparatus for sensing linear displacement of an object between first and second locations along an axis is used to sense conditions that can be made to vary displacement of an object in accordance with the condition, such as temperature, pressure and rotary motion. A light beam projected along an incident light path to the object is reflected along a reflective light path by a reflector affixed to the object. A photo-sensor array in the reflective light path intercepts the reflected light beam and produces samples of the intensity of the reflected image at multiple positions along a line across the array. An imager coupled to the array converts the light samples to representative electrical samples.

Abstract: An oversampled interpolative delta sigma analog-to-digital converter including a delta sigma modulator is provided with a cascade of bit-slice elements at the output of the modulator to form a filter/decimator. Each bit-slice element includes a filter circuit that filters the bit-rate signal in accordance with an arbitrary filter impulse response input signal to provide the converter with a filter characteristic that can be controllably varied without modifying the filter hardware. In each bit-slice element, an adder circuit and a delay circuit decimate the bit-rate signal produced by the delta sigma modulator to provide a digital output signal at a clock cycle rate equal to the Nyquist rate. The filter/decimator also provides encoding of the delta sigma output in 2's complement format.

Abstract: Conversion apparatus is used to convert digital data words to a digit-serial data format wherein digit bit-width is optimal for subsequent processing of the digital data words. Optimization is with regard to throughput efficiency, a measure of integrated circuit performance proportional to throughput rate of integrated circuitry and inversely proportional to the area of that integrated circuitry, comprising processing circuitry and attendant conversion circuitry.

Abstract: Apparatus for measuring or compensating for phase or time delay between a reference signal and a desired signal produces an approximate error signal by differentially summing the desired and reference signals. The appoximate error signal is then used, in a feedback loop, to control application of an adaptive delay to each of the reference and desired signals. The total lead or lag difference is represented by the difference between the two delays applied to the reference and desired signals, respectively. The phase or time delay measurement or compensation arrangements may be applied to linear variable differential transformers, synchronous AM detectors, zero crossing detectors and phase locked loops. Variations on this basic technique can yield substantially exact measurement or compensation. The invention is applicable to sampling arrangements including oversampling/decimation or interpolation/decimation to increase compensation accuracy to any desired degree.

Abstract: One type of transversal filter using digit-serial signals in its operation comprises a to-digit-serial converter for converting a succession of input data words received at its input port each to a respective succession of m-bit-wide digits supplied from its output port in order of progressively greater significance, m being a positive plural integer; a clocked delay line having an input tap connected for responding to the m-bit-wide digits supplied from the output port of the to-digit-serial converter and having at least one further tap for supplying a respective tap signal; and means for performing a weighted summation of the input signal to the clocked delay line and each tap signal from the clocked delay line, to generate a filter response in digit-serial format.
