Abstract: ABSTRACT OF THE DISCLOSURE        A communication switching system for routing digital voice and data signals and message signals between a plurality of peripheral circuits disposed in one or more peripheral subsystems and a main controller.  Each peripheral subsystem is comprised of a peripheral switch matrix controlled by a peripheral control processor for switching the voice and data signals between predetermined peripheral circuits and the circuit switch matrix.  The voice, data and message signals are transmitted through a circuit switch matrix of the main controller on predetermined time slot channels.  The message signals are transmitted via communication controllers associated with the main controller and each of the peripheral subsystems according to a bit oriented data link protocol.  The message signals are transmitted asynchronously during a predetermined one or more dynamically allocated time slot channels of the circuit switch matrix.  The data link protocol guarantees error free transmission of a plurality of message signals.  The communication system is inexpensive and efficient since both voice and data transmission as well as messaging is effected through use of a single circuit switch matrix.

Abstract: ABSTRACT            The present invention relates to optical memories for storing data on the surface of an information-supporting medium including pre-formatted patterns.  Such a memory may constitute a random access mass memory, and it may be a read/write memory or it may be a write-once memory.  The operations of writing to the memory and reading from the memory are based on the optical inter-action which occurs at the point of impact of an lncident optical beam which causes local changes in optical characteristics which are representative of the data when data is being written, and which produce optical modulation detectable by photoelectric means during data reading.  The invention provides an optical memory in which the illumination mode common to reading data and to detecting pre-formatting patterns is modified in order to allow for operation in a standby mode or in order to delete areas reserved for storing data, for example.

Abstract: ABSTRACT         Disclosed is an apparatus for measuring the mean permittivity of a sample of material comprising a sense chamber for containing the sample, the sense chamber comprising a cylin-drical tube of low permittivity, low conductivity material and having an outer surface provided with at least three helical foil electrode structures extending along substantially the entire length of the tube.  Each electrode structure comprises an inner sense electrode in contact with the tube and an outer shield electrode.  The sense electrode and the shield electrode are separated by a thin barrier of insulating material.  The apparatus further comprises a source for applying out of phase alternating voltage signals to the electrode structures to produce a rotating electrical field in the sense chamber and for deriving a voltage read-out signal proportional to the sum of the charging currents applied to the electrode structures, the read-out signal being directly related to the mean permittivity of said sample.

Abstract: NORMALIZED FREQUENCY DOMAIN LMS ADAPTIVE FILTER           ABSTRACT OF THE DISCLOSURE       A normalized  frequency domain Least Means  Square filler is disclosed.  The feedback coefficient for each frequency bin is adjusted separately in the filter by use of an input power estimate.  The power estimate is incor-porated directly into the  filter algorithm as a data-dependent, time-varying stochastic feedback coefficient. The filter is particularly useful in applications in which the  input  signal has  large  spectral variations,  which could lead to filter instabilities in some frequency bins if a  single  feedback coefficient were employed in all frequency bins.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention is an electrical junction box of the type having side portions, a back portion, and an open face portion.  A flange extends completely around the side portions.  This flange is located sufficiently behind the open face of the box to leave a part of the side portions projecting forward of the flange.  The projecting portion normally is equivalent in length to the thickness of the gypsum sheetrock or other wall facing material being used.  At least one wire or cable inlet extends outward from the side portions behind the flange for admitting electrical wiring into the junction box.  These inlets will normally have a plurality of generally tubular apertures entering the interior of the box.  Each aperture is originally sealed with a readily removable press-out diaphragm.  In use, the box is mounted in a wall space to be covered with gypsum board or similar product so that the open face is essentially flush with the room-side surface of the gypsum board and the flange generally bears against the opposite side of the gypsum board.  The flange and wire inlet apertures serve as caulk receiving surfaces to create seals and prevent air interchange between the room and wall space.  Preferably the wire inlet apertures are angled forward to improve access for caulking. The flange is particularly useful in sealing the outlet box to a polyethylene vapor barrier.

Abstract: ABSTRACT           Methods are known for reconstructing magnetic resonance images from a magnetic resonance measurement performed on a body, which methods utilize only one half (or slightly more) of the data of the complete resonance measurement for reaching a resolution corresponding to a complete resonance measurement. Such methods utilize an estimation of the phase of the image from data known as sampling values from a central part of a data matrix filled with the sampling values, the partly filled data matrix being supplemented by zeroes prior to the reconstruction of the image. The known methods offer reasonable results, subject to the condition that the phase of the image varies smoothly and changes slowly in the relevant image dimension. A method is proposed for reducing the residual artefacts, such as blurring, which occurs in the image when the known methods are used, for example due to phase errors. In accordance with the proposed method, a number of steps are performed per column in the data matrix so as to produce an ever better estimation for the data not known from sampling. After the reconstruction, the image will have a phase which at least approximates the phase estimated from the central part of the data matrix. In the case of phase errors, substantially no residual artefacts will remain and at the same time the signal-to-noise ratio in the image will be superior to that obtained by means of the known methods.
