Abstract: MITIGATION OF NOISE SIGNAL CONTRAST IN A DIGITAL      SPEECH INTERPOLATION TRANSMISSION SYSTEM     Abstract of the Disclosure A DSI transmission system is described in which noise signal contrast is mitigated by transmitting not only active channels but also channels which carry background noise, the resolution of the background noise channels being varied in dependence upon the number of channels transmitted.  In the described system, the DSI transmission is effected in superframes each of which consists of an overhead information frame and a plurality of digital message frames. The overhead information frame contains a word indicating the transmission status of each channel during the superframe, a code indicating the number of bits of each digital message, and maximum segment value information bits for each of the active channels which are transmitted using nearly instantaneous companding. Each of the remaining frames contains a digital message in respect of each active channel.  Remaining space in these frames is occupied by digital messages in respect of the background noise channels, which are allocated to the frames by cyclic assignment and are transmitted using compact PCM encoding.          For each superframe, active and background noise channels are determined using speech, echo, and off-hook detectors, and the number of bits of each digital message in the superframe is determined in dependence upon the total number of active and background noise channels.     - i -

Abstract: RCA 74,681 ABSTRACT OF THE DISCLOSURE           A television receiver high voltage generator includes a high voltage transformer for developing an ultor accelerating potential at an ultor output terminal.  A high voltage protection circuit comprises a comparator and a disabling circuit coupled to an output terminal of the comparator.  An ultor accelerating potential representative signal is applied to an input terminal of the comparator to disable normal television receiver operation when the ultor accelerating potential exceeds predetermined values. To avoid nuisance tripping or energization of the disabling circuit at lower beam current levels, beam current information is applied to an input terminal of the comparator such that at low beam current operating levels, a greater ultor accelerating potential must be exceeded before the disabling circuit is energized, than at high beam current operating levels.  The beam current information is applied to the comparator through an amplifier having an output terminal coupled to an input terminal of the comparator and having a beam current representative signal applied to the input terminal of the amplifier.  Biasing of the amplifier is such that over a substantial range of ultor beam current values, the amplifier exhibits a certain gain characteristic but exhibits a substantially different gain characteristic outside this range in order to provide the disabling circuit with an overcurrent shutdown capability.

Abstract: IMPROVED MAGNETIC FIELD SENSING APPARATUS               ABSTRACT OF THE DISCLOSURE      The magnetic field sensing apparatus includes first and second magnetoresistive elements having respective angularly disposed current path portions through which a bias current flows and to which a bias magnetic field is supplied.  An external magnetic signal field is supplied from a magnetic source, and the magnetoresistive elements are relatively displaceable with respect to this source.  The bias field is supplied at an angle of approximately 45° with respect to the direction in which the bias current flows in each current path; and the source of external magnetic field generates a signal field whose polarity gradually decreases and then changes over to an opposite polarity at a boundary region.          This change in the signal field is sensed by the magnetic sensor as it is relatively displaced, thereby producing an output signal that varies substantially linearly with this displacement over a predetermined range on both sides of the boundary region.
