Title: Voiceband signal classification
Inventor: BENVENUTO NEVIO
IPC: H04M11/00
Filed: 1987-10-29
Abstract: A signal is classified as one among a plurality of classifications by employing the autocorrelation (R-(k)) (17,18,20,21) of a complex low-pass version of the signal (y(n) (10-16), i.e., the complex autocorrelation (R(k)). The normalized magnitude (E(k)) (22) of the complex autocorrelation obtained at a prescribed delay interval, i.e., "lag", is compared (via 24) to predetermined threshold values to classify the signal as having one of a plurality of baud rates.

Abstract: For setting the cutting tip (30) of a cutting tool (32) of a lathe, a tool-setting probe (10) has a stylus tip (18) for contacting the tool tip (30). The stylus tip (18) is generally cube-shaped. In addition to a conventional vertical datum surface (36) for setting the tool in the horizontal direction (arrow A), it has a 45° sloping datum surface (38).

Abstract: The invention relates to the digital transmission of an audio signal. To save transmission and/or storage capacity, the digital signal is converted into a signal representing the short-time spectrum before the transmission and components of this signal are processed on the basis of psycho-acoustic rules, components of this signal below predetermined thresholds not being taken into consideration. 
<??>It has been found that the general not taking into consideration can lead to reductions in quality in particular signals. 
<??>The invention provides a remedy for this in that at least a first threshold is defined below which only amplitude values outside of psycho-acoustically distinguishable frequency ranges are not taken into consideration.

Abstract: In an electric heating vessel (1), the vessel bottom (4), which is heated on the underside by a heating resistor (11) and is attached, in particular, via a bayonet closure lock, consists essentially of a metallic material, whereas the vessel shell (3), which directly adjoins the vessel bottom (4) and is tightly connected to the latter, consists essentially of plastic. The vessel bottom (4) has as its highest point adjacent to the vessel shell a measuring zone (20) which influences a temperature sensor (13) of a temperature switch and, as the lowest zone, in the connection region to the vessel shell (3) an annular groove-shaped indentation (21) for residual liquid so that, if the measuring zone (20) becomes dry, there is still liquid remaining in the groove (21) and therefore the connection between the vessel bottom (4) and the vessel shell (3) cannot be thermally overloaded even if the heating resistor (11) is switched on again for a short time. <IMAGE>

Abstract: An outfeed conveyor is arranged beneath a rotary bucket wheel driven to rotate in a predetermined rotational direction. A belt conveyor is arranged downstream of, and a product entrainment arrangement is arranged upstream of, the outfeed conveyor. An endless revolving belt is guided about belt rolls of the outfeed conveyor and upon which come to bear the printed products in inbricated formation. Entrainment elements of the product entrainment arrangement completely stuff the printed products into the pockets of the bucket wheel. Upon ejection of the printed products out of the bucket wheel they are fixedly clamped at their trailing edges between a support element and extensions or cantilever arms of the entrainment elements until the entrainment elements have passed the support element and thus an intersection location between the entrainment elements and the support element. The resiliently arranged extensions of the entrainment elements are pivoted by the support element in a predetermined direction, such as clockwise, so that the printed products are cyclically released. There is thus formed an inbricated formation of the printed products within which all prnited products are aligned and there can be maintained a substantially constant mutual spacing between the individual printed products.

Abstract: A battery (+V) operable information handling and control system, for example for an automotive vehicle electrical system, has a central unit (10) and a number of remote units (20) each connected to the central unit (10) by a respective signalling link (40). The central unit (10) includes processing and control means (13) and power supply means (11) which are turned on to operate the processing and control means (13) in an active mode of the system and are turned off in a sleep mode of the system. During the active mode the processing and control means (13) applies a clock pulse voltage to a data line (41) in each signalling link (40). One of the clock pulse lines (41) is connected to power supply control means (12) in the central unit (10) and to activation voltage drive means (80) in the respective remote unit (20). When the system is in the sleep mode the activation voltage drive means (80) can be enabled by operation of a activation switch (60,61) connected to that remote unit (20) so as to apply to that clock pulse line (41) an activation voltage, substantially the battery +V voltage (12 volts) and lower than the clock pulse voltage (30 volts). The power supply control means (12) is enabled by the activation voltage so as to turn on the power supply means (11) and the activation voltage drive means (80) is then disabled responsive to the clock pulse voltage consequently applied at the start of the active mode.

Abstract: The amount of electrically conductive material in the bottom floor lining of a conventional aluminum reduction cell is reduced by using a non-conductive lining material in its place. The non-conductive material separates the remaining electrically conductive regions from the sidewall linings of the cell and preferably confines the electric­ally conductive material to the "anode shadow" region of the cell floor. The non-conductive material preferably comprises a particulate alumina mixture made up of large shapes which firmly compact together and smaller particles which fill the remaining voids. Optionally, the mixture may be bonded together with amorphous alumina, in which case the mixture can also be used for cell wall linings. The linings can be used in reduction cells of conventional design and reduces undesirable magnetohydrodynamic effects as well as pollution hazards caused by conventional carbonaceous cell linings.

Abstract: A color printer is provided in which a paper sheet (8) is wrapped about a rotatable platen (14) and three colors are printed on the sheet, to obtain an image, by a thermal head (20) and a color ribbon (86) during three rotations of the platen. In a paper feeding device for the printer, a sheet of paper (8) is fed by a feeding roller, from the bottom of a stack of paper sheets in a paper tray (20) through, a feeding guide to the platen. The tray has an opening (24) in its bottom plate (23) so as to expose the lowermost paper sheet stored therein. The feeding roller (38) is provided under the tray and lifts up toward the opening of the tray so as to come in engagement with the lowermost paper sheet, the feeding roller rotating to feed it to the platen. The width of the platen (14) is less than that of the sheet (8) and the circumference thereof is less than the length of the sheet (8). Therefore, when the sheet is wrapped about the platen (14), it extends laterally outward from the ends thereof, and its ends overlap. Accordingly, during printing, the sheet is securely wrapped about the platen and its position does not shift and the extension of the sheet from the edges of the platen allows a sensor (69) to determine a print starting position by sensing a mark of the edge of the sheet (8). Thus, a fixed print starting position is obtained during all three rotations of the platen during the print cycle.

Abstract: A compact, nonvolatile, zero static power, electrically alterable, bistable CMOS latch device is fabricated with single layer of polysilicon. The single polysilicon layer forms the floating gates of the nonvolatile elements of the device. The control gates are formed in the substrate by burried N+ diffusions and are separated from their respective floating gates by a thin oxide dielectric. The circuit can be designed to power-up in a preferred mode even before any programming operation has been performed on it. Thereafter, the circuit is available to be programmed to either of its two stable states. After the programming operation is completed and the circuit is latched to one of its two stable states, the fields across the thin oxide dielectrics are minimal and virtually no read disturb condition exist. Thus, the latch also offers excellent data retention characteristics.
