Abstract: A method is provided for use with a telecommunication relay device adapted to convey voice-band data signals over a given transmission path in a telecommunication network, which relay comprises a transmitter operative to encode and transmit voice-band data information, and a receiver operative to receive and decode said information and regenerate a voice-band data signal therefrom. The method that is provided comprises handling an echo associated with the regenerated signal and returned from the telecommunication network, in order to prevent it from being relayed backwards, thus impairing the voice-band data call process. The method comprises detecting and identifying the returned echo as such, and preventing it from being relayed.

Abstract: A device for applying a sheet of covering material (4, 40) to boxes (1) having at least one wall (2, 200) with an outside surface (5, 50), an inside surface (6, 60) and a free edge (3, 30) intermediate between the surfaces (5, 6; 50, 60) comprises one or more elements (10, 100) for folding a flap (7, 70) of the sheet (4) around the intermediate edge (3, 30) so that the flap (7, 70) is made to cover the edge (3, 30) and then applying the flap (7, 70) to the inside surface (6, 60) of the wall (2, 200).

Abstract: A transceiver unit, particularly for measuring applications, comprising a transmitter (1) for generating a signal, an acquisition antenna (5) for emitting the signal in an acquisition volume and for picking up an effective echo signal reflected by the acquisition volume, as well as a receiver (2) for evaluating an echo signal supplied by the acquisition antenna (5). The echo signal is composed of the effective echo signal and an unwanted echo signal generated by the acquisition antenna (5). In order to compensate for the unwanted echo signal, an antenna simulation (6) is connected via a coupler (3) to the transmitter (1) and the receiver (2) which, after having received the signal, supply an correction signal in proportion to the unwanted echo signal. The coupler so heterodynes the correction signal and the echo signal that the correction signal and the unwanted echo signal cancel out each other.

Abstract: An orthogonal frequency division multiplexed signal transmitting apparatus executes a time-division multiplexing process that inserts a reference signal at a predetermined interval based on reference signal position information into an information signal to be transmitted. The transmitting apparatus generates an orthogonal frequency division multiplexed signal by digital-modulating the time-division multiplexed signal to radiate into a spatial transmission line. An orthogonal frequency division multiplexed signal receiving apparatus receives the signal from the transmitting apparatus to get the reference signal by demodulating the signal.

Abstract: The invention concerns peptides which bind antibodies that are found in elevated levels in body fluids of schizophrenic patients and are found at a lower level or not found at all in body fluids of non-schizophrenic individuals. Using a computerized program, the antigenic epitope of the peptides of the invention is predicted as having a core of hydrophobic amino acids which is surrounded by positively charged amino acids. The peptides of the invention are useful in the diagnosis of schizophrenia in an individual.

Abstract: An image display apparatus includes a diaphragm (9b) arranged at a pupil position. The shape of an aperture of the diaphragm (9b) is similar to the shape of a light source image formed by an illuminating optical system at the pupil position. An area varying mechanism (90) varies the area of the aperture of the diaphragm (9b) in response to a focal length varying operation of a projection lens (9). This prevents an excessive opening from being formed around a light source image cast by the illuminating optical system, thereby preventing the deterioration of displayed images due to unwanted light that may pass through the excessive opening.

Abstract: The present invention is directed to the use of concatenatable Point-To-MultiPoint (PTMP) broadcast messages for displaying display messages, and in particular long display messages requiring two or more PTMP broadcast messages, on personal cellular telecommunications devices. The present invention is achieved by the provision of a pseudo-header including a display message identifier, a PTMP broadcast message field for specifying the number P?1 of PTMP broadcast messages to transport an entire display message, and a PTMP broadcast message counter Q=(1, 2, . . . , P?1, P) for specifying the location of a PTMP broadcast message in that sequence. A pseudo-header may alternatively enable concatenation of two or more macromessages into a supermacromessage.

Abstract: The invention encompasses a glass-ceramic comprising a continuous glass phase and a crystal phase comprising tetragonal leucite, wherein the glass-ceramic has a crack-free glass phase and a crystal phase comprising leucite crystals distributed essentially homogeneously in the glass phase. The crystal phase has a particle size distribution made of from about 5% to about 70% of a first group of leucite crystals having particle sizes of <1 ?m and from about 30% to about 95% of a second group of leucite crystals having particle sizes of ?1 ?m. The proportion of Li2O in the glass-ceramic is preferably below 0.5% by weight. It is preferred that not only the glass phase but also the crystal phase is essentially free of cracks. The corresponding glass-ceramics are particularly suitable for use in the dental sector, in particular as facing ceramics.

Abstract: Determining surface topology of a portion (26) of a three-dimensional structure is provided. An array of incident light beams (36) passing through a focusing optics (42) and a probing face is shone on said portion. The focusing optics defines one or more focal planes forward the probing face in a position which can be changed (72) by the focusing optics. The beams generate illuminated spots (52) on the structure and the intensity of returning light rays propagating in an optical path opposite to that of the incident light rays is measured (60) at various positions of the focal plane(s). By determining spot-specific positions yielding a maximum intensity of the returned light beams, data is generated which is representative of said topology.
