Abstract: A method and apparatus for encoding a television source signal having a first bandwidth, into a frequency multiplexed signal having a narrower bandwidth and comprising a plurality of subcarriers modulated with digital information. Each of said subcarriers has an amplitude, bandwidth and coding characteristic which reflects the relative importance of the digital information provided thereby. The frequency multiplexed signal is suitable for use in a broadcasting environment wherein a conventional television signal is also used and wherein said subcarriers are disposed in frequency, in positions which are least likely to result in interference to or from said conventional signal. The invention also includes a receiver for decoding the frequency multiplexed signal and for providing a high definition display.

Abstract: Certain crystalline organic semiconductor compounds, such as 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA), when deposited by an ultrahigh vacuum process of organic molecular beam deposition, form highly ordered "quasi-epitaxial" films  (32) . Due to asymmetries in the molecular crystal structure of such compounds, the ordering of the films results in giant asymmetries in their dielectric properties. Such large dielectric asymmetries permit the construction of a variety of devices, including optical isolators  (38) , optically isolated lasers  (48) , optical isolated optical amplifiers  (64) , polarization-selective photodiodes  (76) , and metal-organic-inorganic semiconductor-metal detectors, among others.

Abstract: A magnetic powder for magnetic recording is disclosed which comprises composite type magnetic particles (A), each of which contains hexagonal ferrite and spinel structure ferrite, and single phase type magnetic particles of hexagonal ferrite (B). When the mixing ratio [(A) : (B)] of (A) and (B) in the range from 5 : 95 to 95 : 5, remarkable effect can be obtained. Especially, when the mixing ratio of (A) and (B) is in the range from 5 : 95 to 30 : 70, the dispersion property is improved due to disturbance of magnetic stacking. Thus, the magnetic powder in this mixing ratio is particularly suitable for magnetic recording in a short wavelength range. When the mixing ratio of (A) and (B) is in the range from 70 : 30 to 95 : 5, the reproduction output is improved due to activation of (A). Thus, the magnetic powder in this mixing ratio is specifically suitable for magnetic recording in a long wavelength range. By containing the magnetic powder described above, a perpendicular magnetic recording medium with high electromagnetic characteristics, particularly a high S/N ratio and a low noise can be obtained.

IPC: G11B7/12

Abstract: An optical storage system is described which utilizes the principles of optical stethoscopy to provide subwavelength resolving power thus allowing high areal bit density to be achieved. The optical head includes one or more optical elements (33) mounted on a slider (31) which is in physical, sliding contact with the recording medium (30). Optical elements couple a light beam to a submicron optical aperture (37) formed in the lower surface of the slider to be transmitted to the storage medium. The slider is fabricated from a crystalline material which has a non-linear load versus friction characteristic in the negative load region. When the head is in sliding contact with the recording medium surface, a restoring force is generated which maintains the optical head in physical contact with the recording medium overcoming any lifting forces generated by the moving air layer adjacent the recording medium surface. This restoring force also allows the head to be operated with a negative external load applied. Utilizing an optical head having the light transmission aperture formed in the slider in close proximity to the storage medium surface allows high density recording to be achieved without the requirement of an electro-mechanical servo system to provide beam focusing for the system.

Abstract: Improved system and method for speaker-independent speech token recognition are described. The system is neural network-based and involves processing a sequence of spoken utterance, e.g. separately articulated letters of a name, to identify the same based upon a highest probability match of each utterance with learned speech tokens, e.g. the letters of the English language alphabet, and based upon a highest probability match of the uttered sequence with a defined utterance library, e.g. a list of names. First, the spoken utterance is digitized or captured and processed into a spectral representation. Second, discrete time frames of the spectral representation are classified phonetically using the spectral coefficients. Third, the time-frame outputs are used by a modified Viterbi search to locate segment boundaries, near which such segment boundaries lies the information that is needed to discriminate letters. Fourth, the segmented or bounded representation is reclassified using such information into individual hypothesized letters. Fifth, successive, hypothesized letter scores are analyzed to obtain a high probability match with a spelled word within the utterance library. The system and method comprehend finer distinctions near points of interest used to discriminate difficult-to-recognize letter pair differences such as M/N, B/D, etc.. The system is described in the context of phone line reception of names spelled by remote users.

Abstract: The present invention provides a frequency synthesizer which can be switched at a high speed and generates signals having a relatively high frequency with low power consumption; comprising a clock generator (21), a frequency setting circuit (10) in which phase increment for unit clock can be programmed, a phase accumulator (12) in which phase increment is accumulated, a ROM (14) which outputs a digital signal corresponding to cumulative phase output, a D/A convertor (15) which inverts polarity of output in each clock time, and a band-pass filter (22). The frequency synthesizer constitutes a direct digital synthesizer (DDS) whose output signal is supplied to a phase locked loop (PLL) comprising a            1       N              frequency divider. Because a bandpass filter (22) is connected to the output of the D/A converter (15) instead of a low-pass filter, a higher reference frequency can be supplied to the PLL.

Abstract: A more favorable energy and current distribution is obtained by introducing lossy elements in one or more paths, or by capacitor-switching methods, where RVA is given one polarity, and at least two of the other electrodes are given opposite polarity, yielding at least two pathways. A current and energy steering by means of differing pulse durations in different paths is described. Further, it derives a rectangular current waveform from a capacitor discharge by using a current limiter. This pulse-shaping method is equally applicable to single-path and multiple-path situations. A rectangular pulse delivers a maximum of energy for a given peak-field value with a particular electrode combination and pulse duration. Peak field is a measure of the tissue-damage potentiality of a particular discharge.

Abstract: First hardware means, comprising a given number of prior-art image-pyramid stages (406-1, 406-n), together with second hardware means, comprising the same given number of novel motion-vector stages (416-1, 416-n), perform cost-effective hierarchical motion analysis (HMA) in real time, with minimum system processing delay and/or employing minimum hardware structure. Specifically, the first and second hardware means, in response to relatively high-resolution image data from an ongoing input series of successive given pixel-density image-data frames that occur at a relatively high frame rate (e.g., 30 frames per second), derives, after a certain processing-system delay, an ongoing output series of successive given pixel-density vector-data frames that occur at the same given frame rate. Each vector-data frame is indicative of image motion occurring between each pair of successive image frames.

Abstract: A communication system is prepared to be placed into service, or an in-service system is updated or re-started, by transmitting programs and data into the peripheral equipment of the communication system. So that the availability of the communication system for the connected subscribers remains assured, there is a need for accelerated loading. The loading ensues by segmenting the programs and data on the storage medium at the central station as well as by the transmission of the segments into the designated peripheral units. A synchronous connection is provided between two redundant peripheral units forming a pair and is utilized in the loading event to transfer data or programs as needed between the units of the pair.
