Title: Compatible and spectrum efficient high definition television
Inventor: ZUCKER LEO
IPC: H04N7/06
Filed: 1990-01-25
Abstract: ABSTRACT OF THE DISCLOSURE     High definition television (HDTV) signals are transmitted in a manner to be compatible with television receivers that operate to reproduce standard definition images, and the broadcast HDTV signals can be contained within an existing frequency band allocated for transmission of the standard definition images.  A high definition image source generates an image with a resolution of N horizontal lines, wherein N is a positive number equal to about twice the line resolution of a standard definition television image frame.  Odd line image signals corresponding to each odd numbered line of the image frame, and even line image signals corresponding to each even numbered line of the image frame, are separately derived.          The odd line image signals are modulated on a radio frequency (RF) carrier wave signal to produce HDTV odd line image signals occupying at most the same frequency band or channel as occupied by standard definition images, and the even line image signals are modulated on a RF carrier wave signal to produce HDTV even line image signals that occupy at most the same frequency band or channel as occupied by standard definition images.  The odd and the even line image signals are simultaneously radiated from respective antennas having mutually orthogonal polarizations.

Patent CA-2013872-A1 (CA)
Title: Electric motor speed control apparatus and method
Inventor: ROWAN TIMOTHY M
IPC: H02P3/18
Filed: 1990-04-04
Abstract: The speed of an induction motor is reduced by initially using dynamic electrical braking to slow the motor to a speed at which it will not remain synchronized to the A.C. supply frequency. At this point, A.C. cycle skipping is employed to apply current to the motor at an effective frequency which is a fundamental frequency component of the A.C. supply line frequency. The motor becomes synchronized to this fundamental frequency component. If desired, the motor can be brought to a complete stop by discontinuing the cycle skipping and using the dynamic braking again for a given period of time. This technique provides a very controlled stopping of the motor enabling equipment driven by the motor to be accurately positioned.

Abstract: ABSTRACT OF THE DISCLOSURE     A text-to-speech synthesizer comprises an analyzer that decomposes a sequence of input characters into phoneme components and classifies them as a first group of phoneme components or a second group if they are to be synthesized by a speech parameter or by a formant rule respectively. Speech parameters derived from natural human speech are stored in first memory locations corresponding to the phoneme components of the first group and the stored speech parameters are recalled from the first memory in response to each of the phoneme components of the first group. formant rules capable of generating formant transition patterns are stored in second memory locations corresponding to the phoneme components of the second group the formant rules being recalled from the second memory in response to each of the phoneme components of the second group. Formant transition patterns are derived from the formant rule recalled from the second memory and formants of the derived transition patterns are converted into corresponding speech parameters. Spoken words are digitally synthesized from the speech parameters recalled from the first memory as well as from those supplied from the converted speech parameters.

Title: Active-fiber optical amplifier and ytterbium doped fiber therefor
Inventor: GRASSO GIORGIO
IPC: G02B6/02
Filed: 1990-11-09
Abstract: ABSTRACT OF THE DISCLOSURE An optical amplifier and an active optical fiber therefor, particularly for optical fiber telecommunications lines, includes an erbium-doped, laser-emission, active optical fiber and a light pumping laser source operating at a predetermined wavelength.          The active optical fiber further includes ytterbium as a further dopant, which further dopant exhibits an absorption of light at the emission wavelength of the pumping laser emitter, for example, a commercially available three-level diode-pumped laser of the Nd:YAG type, operating between 900 and 950 nm which is different from the wavelength at which erbium alone can be pumped.  The further dopant is adapted to transfer the energy thus absorbed to the erbium contained in the fiber, thereby causing a population inversion thereof adapted to generate a stimulated light emission in the presence of an optical transmission signal.  The use of ytterbium in the active fiber enables the achievement of a sufficiently wide spectrum of absorption so that the use of a laser of high power and low cost for the active fiber pumping within the amplifier is made possible.
