IPC: H04N9/64
Filed: 1991-03-25
Abstract: Bei einer Schaltungsanordnung zum Versteilern von Signalflanken eines als Folge amplitudendiskreter Abtastwerte eines Analogsignals vorliegenden Digitalsignals ist vorgesehen, daß das zu versteilernde Digitalsignal einem Flankendetektor (1) zugeführt wird, welcher während der Zeitspanne, in der eine Flanke des Digitalsignals einen vorgebbaren Steilheitswert überschreitet, ein Markierungssignal abgibt, daß eine Verzögerungsvorrichtung (5) vorgesehen ist, in welcher das Digitalsignal und das Markierungssignal um eine feste Zeitspanne verzögert werden, daß ein FIFO-Speicher (6) vorgesehen ist, in dem zum Zeitpunkt des Endes der nicht verzögerten Sequenz der Amplitudenwerte des Digitalsignals eingelesen und zum Zeitpunkt des Beginns der verzögerten Sequenz wieder ausgelesen wird, und daß ein Sequenzgenerator (8, 22) vorgesehen ist, welcher unter Heranziehung des verzögerten Digitalsignals, des verzögerten Markierungssignals und des aus dem FIFO-Speicher ausgelesenen Wertes ein versteilertes Signal generiert und mit Hilfe eines Multiplexers (12) in das verzögerte Digitalsignal anstelle der ursprünglichen Sequenz des Signals einsetzt. <IMAGE>

IPC: G01R29/24
Filed: 1991-02-05
Abstract: Disclosed is a multi-channel electrostatic sensor apparatus comprising essentially a single main oscillation circuit; a plurality of pull-in type sub-oscillation circuits which are adapted to synchronize with said main oscillation circuit to generate sub-frequency signals whose frequency is equal to the main oscillation frequency or a multiple thereof; and a plurality of resonance circuits which are sensitive to any change in exterior capacitance when detected by an associated detector for changing its resonator resonance point with respect to the sub-frequency signal. Positive synchronization of the sub-oscillation circuits with the single main oscillation circuit prevents any adverse effect from being caused by the varying stray capacitance in flexible conductors connecting the sub-oscillation circuits to the main oscillation circuit while allowing the relatively free movement of the video heads of a video system, on which magnetic heads the sub-oscillation circuits and subsequent components are attached.

Abstract: This invention relates to a personal computer with a folding keyboard and, more particularly, to a personal computer contained within a compact enclosure when stored in a non-use position. The personal computer has a clamshell enclosure having first and second housings joined for pivotal movement one relative to the other about an elongate housing axis and between a folded position and a use position. Computer operating components are mounted in the enclosure. A keyboard assembly is operatively associated with the enclosure and the computer operating components and has first and second keyboard portions each bearing manually engageable elements for entering characters and commands. The portions are coupled together for pivotal movement one relative to the other about a keyboard axis perperdicular to the housing axis and coupled with the enclosure for sliding movement relative between a folded, stored position interposed between the housings and an opened, use position partially displaced from and overlying a side edge of the enclosure The keyboard assembly has, when folded about the keyboard axis, dimensions received wholly within the outline configuration of the enclosure.

Abstract: The laser, usable in metrology, delivers two waves at different frequencies, having mutually orthogonal linear polarisations. It comprises a laser medium placed in a laser resonant cavity delimited by mirrors and associated with means of exciting the laser medium and comprising a birefringent component placed in the path of the two waves. The active laser medium is in a location in the cavity where the two waves are spatially separated and two quarter-wave plates (20, 22), one of which exhibits neutral lines substantially 45 DEG  from the axes of polarisation of the birefringent component (18), are placed in the path of the two waves in order to give these waves a helicoidal polarisation between the plates.

Abstract: In battery-operated small electronic devices (1) such as radio devices, cassette devices, CD devices, dictating devices and the like, headphones which can be connected to a connecting socket (4) are in most cases used for reproducing electroacoustic signals. So that the batteries (12) do not need to be taken out of the device for charging purposes, it is proposed to use the connecting socket (4) for connecting a charging voltage source. This is made possible by the fact that a bipolar capacitor (9) is inserted between the output of a headphone amplifier (2) and a connecting contact (5) of a connecting socket (4) and a charging resistor (10) and a diode (11) are inserted between the connecting contact (5) and the batteries (12). <IMAGE>

Abstract: A data processing system has access to a memory storing a data or other information base. The data processing system evaluates objects from the data base against search criteria generated from parameters entered into the data processing system by a user. As objects are located by execution of a search program meeting the search criteria, those objects are identified to the user while the search continues. The user can access the object for substantive evaluation for conformance to the desired target data. The user may enter modified parameters based upon his evaluation of such results as obtained. The data processing system then continues the search over each part of the database as the user designates.

Abstract: The invention relates to purified thermostable DNA polymerases from Pyrodictium species, such as Pyrodictium occultum or Pyrodictium abyssi, which polymerases catalyze the combination of nucleoside triphosphates to form a nucleic acid strand complementary to a nucleic acid template strand. The preferred polymerases are characterized by their ability to function efficiently in a polymerase chain reaction, wherein said reaction includes repeated exposure to a denaturation temperature of about 100°C. Most preferably the polymerases display 5'→3' exonuclease activity, i.e. are proofreading enzymes. The invention also provides DNAs encoding the DNA polymerase activity of the said Pyrodictium species, which DNAs can be used to construct recombinant vectors and transformed host cells for production of polypeptides having said activity. The invention also relates to the preparation of said thermostable DNA polymerases, to the use of said polymerases to amplify nucleic acids as well as to kits comprising a polymerase of the present invention.

Abstract: Apparatus for monitoring gaseous oxygen concentration that includes an oxygen sensor for providing an electrical sensor signal that varies as a function of oxygen concentration at the sensor. Processor circuitry compares oxygen concentration indicated by the sensor signal to at least one threshold level, and indicates when such oxygen concentration at the sensor departs from such threshold concentration level. The apparatus is calibrated by exposing the sensor to a calibration gas having an oxygen concentration equal to the desired threshold concentration level, and storing in the processor circuitry electrical indicia indicative of operating characteristics of the sensor at such threshold oxygen concentration level. When the apparatus is thereafter employed for monitoring a gas of undetermined oxygen concentration, the operating characteristics of the sensor reflected by the sensor output signal are compared to the prestored indicia for determining when oxygen concentration at the sensor crosses the threshold concentration level.
