Inventor: SUYAMA MASUO
IPC: H04B10/294
Filed: 1990-08-31
Abstract: An optical communication system in which transmission of information with a pumping light beam acting as the carrier, in addition to transmission of information with a signal light beam, is made possible is disclosed. This optical communication system includes an optical fiber amplifier (24) adapted to amplify a signal light beam by having the signal light beam and a pumping light beam propagated through its rare-earth-­doped fiber (28) doped with a rare earth element and a modulating circuit (48) for modulating the pumping light beam with a high-frequency modulating signal having a period shorter than the life span of fluorescence resulting from an excited state. In the case where the signal light beam and the pumping light beam are propagated in the same direction through the rare-earth-doped fiber, the transmission of information with the pumping light beam acting as the carrier can constitute a transmission of supervisory signal for an optical repeater, and in the case where the signal light beam and the pumping light beam are propagated in the directions opposite to each other through the rare-earth-doped fiber, a two-way transmission can be achieved by the transmission of   information with the signal light beam and the transmission of information with the pumping light beam.

Abstract: In a circuit arrangement for detecting synchronisation pulses contained in a digital television signal by means of a separating stage, it is provided that during the times in which television signal components are separated in the separating stage and, at the same time, the current sample exceeds a stored sample in the direction of the level of the synchronisation pulses, the stored sample is replaced by the current one and, at the same time, a marking signal is generated. In each time interval between successive synchronisation pulses, the stored sample is deleted at a predeterminable time valid for all time intervals. The last marking pulse in each case before such a deleting process marks a detected synchronisation pulse.

Abstract: A computer storage DAT drive which detects the form of a DAT tape and provides an audio signal output in response to an audio DAT tape. The drive rewinds the tape and then plays the tape at a speed that is about 5 to 15 times normal playback speed. During such playback, the tape length is determined and the subcode information is read to determine the format of the tape being played back. If the subcode tape format information reliably indicates the presence of an audio tape, the speed of playback is reduced to normal playback, and audio data interface circuitry (91) is enabled for processing the audio data and providing an audio output signal to a front panel audio jack (95), for example. If the tape is not recognized as an audio tape within the playback of a predetermined length of tape, playback speed is reduced to normal playback speed and reading of the subcode information continues. If the subcode tape format information indi­cates that the tape is a computer data storage tape, the tape is read in accordance with the appropriate data storage format. Otherwise, the tape is determined to be blank or erased tape, and playback is stopped. 
     A front panel eject pushbutton is utilized to provide basic controls for controlling the play of an audio tape, and front panel LEDs provide drive and cartridge status indications, including the presence of an audio format tape.

The portable computer communicates with a mainframe computer on which certain dealer inventory information is maintained. Software, residing on a disk which is accessible by the portable computer, allows for the input of dealer codes which are used to identify inventory information which is downloaded from the mainframe computer to the portable computer. The inventory information is used to support an audit of a dealer's inventory. The system of the present invention provides an auditor with an up-to-date record a dealer's current inventory. The system also provides the auditor with a means for printing out a checklist for use in undertaking the inventory, for preparing reconciliation reports for verifying the auditor's findings with the dealer and input means for inputting the results of the inventory. Ultimately, a final inventory report can be printed which includes the present status of all inventory items and any and all charges collected.

Abstract: An etch rate monitor for use with semiconductor wafer etching processes includes a source of light (28) of normal incidence to the wafer surface through a window (26) in the etching chamber (10). In a first embodiment, a Fresnal or positive lens (36) is used to collect some of the diffraction orders caused by the repetitive patterns on the wafer surface (18, 20) which merge from the window (26). In alternate embodiments, a concave spherical mirror and/or a phototdetector system are used to collect the diffraction orders. A collimating lens (42) applies these diffraction orders of normal incidence to interference filters (40) which reject plasma and ambient light and pass the diffraction orders to a photodetector (38) to monitor etch rate as a function of the cycle period between interference minima or maxima caused by the difference in path length between the etched and not etched surfaces of the wafer.

Abstract: An automatic gain control (AGC) circuit for use in an optical code reader which eliminates error caused when regular reflecting light is directly incident on the detector element of the optical code reader. The AGC has a variable gain amplifier (30) which receives a signal from the detection element and outputs a signal to a peak-holding circuit (40). The output from the peak-holding circuit is used to control the gain of the variable gain amplifier. A reset circuit (60) resets the output of the peak-holding circuit either when the output reaches a predetermined level, or at regular intervals during the operation of the optical code reader. The output of the variable gain amplifier is fed to a binary circuit.

Abstract: 2.1 It is intended to achieve a high quality of the motion vectors with little computing effort. In this connection, it is intended to access as rapidly as possible those image blocks which exhibit movement and are particularly suitable for determining accurate motion vectors. In addition, it is intended to specify a comparison method which allows a particularly rapid and accurate determination of motion vectors without extensive calculation. 2.2 In an image block memory, all image blocks which exhibit a change compared with the previous frame are provided with a motion marker. In addition, all the images blocks which have sharp contours in the horizontal and vertical direction are provided with a structure marker. When motion vectors are determined, initially only those image blocks are processed which exhibit a motion marker and a structure marker. It is only after that that the other image blocks only exhibiting a motion marker are processed. When motion vectors are determined, hypothetical motion vectors can also be formed which are determined taking into consideration the previous motion vector of the same image block and the previously calculated motion vectors. These are used for carrying out a comparison with an image block in the previous frame, offset by the hypothetical motion vector. The difference values produced during this process are compared with one another and weighted. 2.3 The direct access to image blocks which are provided with a motion marker and a structure marker makes it possible to find those image blocks which are particularly suitable for rapidly determining an accurate motion vector. This saves computing time and results in a high quality of the motion vectors. <IMAGE>

Abstract: The present invention is directed to a method for making a chopped fiber-reinforced composite. The method comprises dispersing a polyamide acid/epoxy blend and greater than 50 wt-% chopped fiber in an aerated surfactant foam. The foam is deposited on a foraminous layer and collapsed to form a web. The web is consolidated at a temperature of greater than about 280°C and a pressure of greater than about 500 psi. The resulting composite typically has a flexural modulus of greater than 2,000 ksi and flexural strength values of greater than about 30,000 psi and typically between about 30,000 and 50,000 psi. The composite should find use in applications requiring effective high mechanical stiffness and strength, and flame resistance.
