Patent EP-0400756-A2 (EP)
Inventor: AZADEGAN FARAMARZ
IPC: H04N7/30
Filed: 1990-05-30
Abstract: A method and apparatus for digital encoding are described for compressing the augmentation channel signals (chrominance and luminance signals for panel information and high frequency luminance and line sifference signal) so that this information can be transmitted in a 3 MHz wide RF channel using a digital transmission scheme such as QPSK. Analog signal components are sampled and converted to digital signals. Each of the signals is fed into a separate coder which reduces the number of bits/pixel required to reconstruct the original signal. Compression is achieved by quantization and removal of redundancy. The compression scheme is based on the use of DCT together with VLC. Each augmen­tation signal has its own coder, which is adapted to the unique statistics of this signal.

Abstract: An apparatus (30) and method for generating a highly conductive channel for the flow of plasma current between the electrodes (48) of an ignitor gap (46) device are disclosed. A high voltage transformer (T1) having a high turns ratio is used to produce a high voltage spark across an ignitor gap (46). Subsequently, a high voltage low turns ratio transformer (T2) is used to supply a pre-plasma current signal to the ignitor gap at a predetermined time following the high voltage spark thereby ensuring that the ionized channel is developed to a more conductive state prior to introduction of the pre-plasma signal into the ignitor gap. Once the sustaining voltage for sustaining plasma flow through the channel has stabilized to a sufficiently low voltage, a high current main plasma signal is supplied to the ignitor gap (46) thereby expanding plasma flow in the area surrounding the ignitor gap (46) and providing a high quality ignition source for use in internal combustion engines.

Abstract: The strokes performed in the direction of the injection axis by a valve-actuating cylinder disposed near the rear portion of the plasticizing cylinder are transformed by a motion-deflecting lever into opening and closing movements of the valve needle. The motion-deflecting lever is disposed within the protective skeleton, which surrounds the plasticizing cylinder. The lever is pivoted to the skeleton by a supporting pivot assembly. The valve needle extends rearwardly to a location which is radially aligned with the feed screw when it is in its foremost position. The valve needle extends in a needle-guiding bore, which is formed in the plasticizing cylinder and has a relatively wide rear portion having an open rear end at a location which is radially aligned with the back flow valve when the feed screw is in its foremost position. Owing to that design the assembly by which movement is effected by the valve-actuating cylinder in the direction of the injection axis and transmitted to the valve needle, which is inclined relative to the injection axis, can be manufactured at much lower cost.

Abstract: A database management system comprises a plurality of sites having a computer, a database and a clock. The plurality of sites are interconnectad by a communication line. The database stores a plurality of data for processing. When a transaction request is generated in a site, the transaction management section of the computer in the site examines which database includes necessary data for executing the transaction. Maximum delay decision section determines maximum delay to send an instruction to the site having the database examined. Locktime decision section determines locktime according to the maxmum delay determined and the current time of the clock. Then, the transaction management section sends the locktime as a lock instruction to the site having the database examined through the communication line. A scheduler section receives the lock instruction sent by the transaction managemant section. A lock activation section activates the scheduler section when the locktime coincides with the current time of the clock. The scheduler section locks the necessary data in the database in response to activation by the lock activation section.
