Abstract: An interframe coding apparatus performs motion detection and vector quantization on the basis of a block of interframe differential signals and includes a vector quantizer. The data of the interframe differential signal or the block scanning predictive error signal is compressed using a vector quantizer. 
     The vector quantizer receives a plurality of suppressed predictive error signals (624) as input signals in block form and operates to form input vectors. The data is analysed by a motion detector (652) and where motion is detected, the relevant block is coded as a significant block. A coder (638-642) operates to determine an output vector having the least distortion with respect to an input vector by various techniques. A coded output or output vector codetable address (625) is output from the coder of the device for receipt by a decoder (639,642,654,655) which constructs a proper output vector signal.

Abstract: The present invention relates to a sealing member preferably for sealing of the sides of the pressing zone of filter presses used in the pulp and paper industry. The sealing member according to the present invention solves the problems mentioned above because the sealing members (36, 38), made of practically permanent material which is ideal as to its friction properties relative to the wire surfaces, are constructed to form a single sealing member (30) together with the support members (32, 34), which sealing member (30) allows bending thereof conforming to the movements of the press wires, but prevents the tendency of the sealing member to bend, which tendency is caused by the pressure of pulp.

Abstract: A method for fabricating a coplanar full width scanning array (40) from a plurality of relatively short scanning subunits (20) for reading and writing images. The subunits are fixedly mounted in an end-to-end relationship on a flat structural member (30) with the subunit surfaces containing the scanning elements (12) all being coplanar even though at least some of the subunits have varying thickness. This is accomplished by forming from a photopatternable thick film layer (14) one or more keys (18, 38) on the subunit surface having the scanning elements and associated circuitry and positioning the keys into keyways (28, 39) produced from a photo­patternable thick film layer (23) on a flat surface of an alignment fixture (24). A conformal adhesive (36) bonds the structural member to the assembled subunits to form the full width scanning array.

The intermediate gear (67) is in engagement with the pinion (53) and is moved forwardly to engage with the ring gear (30) of an internal combustion engine. The shift coupler (68) of the present invention includes an annular portion (68a) which is loosely mounted on the rear end portion of the clutch outer of the overrunning clutch (50) in such a manner that the axial movement thereof is limited, and an engaging portion (68b) extended radially of the annular portion (68a). The engaging portion (68b) is engaged with the boss of the intermediate gear (67) over at least a half of the outer periphery thereof and limited in axial movement. 
When the swing of the shift lever (20) is transmitted axially to the annular portion (68a) or the boss of the intermediate gear (67), the overrunning clutch (50) and the intermediate gear (67) are moved axially being operated through the shift coupler (68). Therefore, the smooth axial movement of the intermeidate gear (67) can be achieved.

Abstract: A coplanar waveguide based microwave monolithic integrated circuit (MMIC) oscillator chip (14) has an active oscillator element (16) and a resonant capacitor (18) formed thereon and is flip-chip mounted on a dielectric substrate (12). A resonant inductor (22) is formed on the substrate (12) and interconnected with the resonant capacitor (18) to form a high Q-factor resonant circuit for the oscillator (10). The resonant inductor (22) includes a shorted coplanar waveguide section (24) consisting of first and second ground strips (24b, 24c), and a conductor strip (24a) extending between the first and second ground strips (24b, 24c) in parallel relation thereto and being separated therefrom by first and second spaces (26a, 26b), respectively. A shorting strip (24d) electrically interconnects adjacent ends of the conductor strip (24a) and first and second ground strips (24b, 24c), respectively. A dielectric film (34) may be formed over at least adjacent portions of the conductor strip (24a) and first and second ground strips (24b, 24c). The resonant inductor (22) is adjusted to provide a predetermined resonant frequency for the oscillator (10) by using a laser to remove part of the dielectric film (34) in the first and second spaces (26a, 26b) for fine adjustment, and/or to remove part of the shorting strip (24d) at the ends of the first and second spaces (26a, 26b) for coarse adjustment.

Abstract: Cross-luminance and cross-color artifacts can be eliminated if in an extended encoder the chrominance information is made pairwise equal at two time instants and the luminance information (i.e. the high horizontal frequencies) is also made equal at these two time instants. In an extended decoder, the high-frequency luminance information can be separated again from the modulated chrominance information by, for example, (i) subtracting the information of the pairs at the above-mentioned time instants and by dividing them by 2 (this yields chrominance), and by (ii) averaging the information of the pairs at these time instants (this yields high-frequency luminance).

Abstract: To reduce the maximum possible switching transient, each new word (22a) to be applied to the bus (60) is compared to the word (22b) already on the bus (60), and, if the two words differ by more than half the number of bits in each word, the polarity of the bus (60) is inverted by XOR gates (24₀ .. 24 N-1 ). In this way, no more than half the number of bits in each word will have to change at one time. Comparison logic (50) at the transmitting end of the bus (60) compares the two words stored in latches (22a, 22b). Also, both the transmitting and receiving ends of the bus (60) contain inverting logic (24₀ .. 24 N-1 ; 44₀ ..44 N-1 ). In a second embodiment of the invention, the polarity of the bus is inverted if more than half of the bits in a word to be applied to the bus are logic zero. A method for applying this technique to non-volatile memories in order to reduce fatigue is also disclosed.

Abstract: Circuits (260) for increasing throughput in random repetitive signal acquisition systems that use triggers (100). The circuits (260) allow the random repetitive signal acquisition systems to terminate an acquisition only when there is a high probability that usable samples have reached the systems. The circuits comprise logic elements (320) for producing a qualifier signal (350) having at least two input ports (330,340). A first delay element (300) is coupled to a first input (330) of the logic element (320) for introducing a first delay (270) in a sample signal (290), thereby producing a first delayed sample signal for setting the logic element (320) and enabling the qualifier signal (350). A second delay element (310) is coupled to a second input port (340) of the logic element (320) for introducing a second delay (280) in the sample signal (290), thereby producing a second delayed sample signal for resetting the logic element (320) and disabling the qualifier signal (350). The qualifying signal (350) qualifies a trigger signal produced by trigger circuitry (100) in the random repetitive signal acquisition system. The qualifier signal (350) is generally periodic and is particularly useful in qualifying a trigger signal in a digitizing oscilloscope.
