Abstract: IMPROVEMENTS IN CONTINUOUS SPEECH RECOGNITION                    ABSTRACT OF THE DISCLOSURE         An improved speech recognition method and apparatus for recognizing keywords in a continuous audio signal are disclosed. The keywords, generally either a word or a string of words, are each represented by an element template defined by a plurality of target patterns.  Each target pattern is represented by a plurality of statistics describing the expected behavior of a group of spectra selected from plural short-term spectra generated by processing of the incoming audio.  The incoming audio spectra are processed to enhance the separation between the spectral pattern classes during later analysis.  The processed audio spectra are grouped into multi-frame spectral patterns and are compared, using likelihood statistics, with the target patterns of the element templates.  Each multi-frame pattern is forced to contribute to each of a plurality of pattern scores as represented by the element templates.  The method and apparatus use speaker independent word models during the training stage to generate, automatically, improved target patterns.  The apparatus and method further employ grammatical syntax during the training stage for identifying the boundaries of unknown keywords.  During the recognition process, improved performance is achieved by use of alternate spellings for "silence" and memory requirements and the computational load is reduced using an augmented grammatical syntax.  A concatenation technique is employed, using dynamic programming techniques, to determine the correct identity of the word string.

Abstract: A BATON PASSING METHOD AND APPARATUS FOR MAINTAINING SYNCHRONIZATION IN A TDMA SATELLITE COMMUNICATION SYSTEM                        Abstract In a TDMA satellite communication system, one of the stations is elected the primary station which transmits a reference burst to all other stations to synchronize the local clocks in each station.  Each subsidiary station in turn responds by transmitting a local trans-mit reference burst to enable synchronization of the local transmit clocks.  In order to assure that the synchronous operation of the network will continue when the reference station experiences a failure, an alternate reference station is designated in the network which will assume the role of the primary reference station in a baton passing operation in the event that the existing primary reference station must abdicate its reference role.  An improved method and apparatus for carrying out the baton passing operation monitors the channel error rate at the reference station and the alternate station. The error rate is measured by detecting FEC from as-sessing the error syndromes in the reference bursts from the reference station as received at the reference and alternate stations.  This refined monitoring technique is combined with the coarser technique of monitoring the number of negative acknowledgement signals from the subsidiary stations indicating that they have not correctly received reference bursts, to yield a more refined determination at the reference stations of its effective-ness as a reference station.  The alternate station uses a similar technique to determine if it is sufficiently healthy to play the role of alternate station.            In addition all earth stations equipped with the channel error rate measuring device can inhibit their operation during extreme channel error conditions.

Abstract: ABSTRACT: "Method of adjusting the current intensity of an electron beam in a pick-up tube and television camera system suitable therefor".           In a television camera comprising at least one pick-up tube (PT) it is desirable to generate an electron beam (ER) with a current intensity which is greater than strictly necessary for obtaining a picture signal (PS) with a nominal amplitude between a black level and a white value. This prevents comet tails from being pro-duced on display behind brighter, moving scene portions, caused by an insufficient stabilization of a potential image scanned by the beam (ER). Instead of acting in the optical path, electronic action is taken on the beam current setting. To that end the electron beam is blanked periodically during a beam current setting period before each field period in which a field scan is effected, during at least one preceding field period and within said field period(s) during at least a line period portion of at least one plurality of consecutive line periods. Setting is effected to a maximum picture signal amplitude to be reached at a substantially minimum beam current intensity.
