Title: Diversity receiver using matched filter and decision feedback equalizer
Inventor: TSUJIMOTO ICHIRO
IPC: H04B7/06
Filed: 1991-05-31
Abstract: In a digital radio communications system, a transmit signal is delayed and sent on a first diversity channel and a nondelayed version of the signal sent on a second diversity channel. At the receiving site, first and second diversity channel signals are recovered and normalized into first and second constant-amplitude signals. Predominant components of the constant-amplitude signals are phase-and-amplitude aligned with each other by feedback loops including phase-and-amplitude alignment circuits, an adder and an AGC amplifier. The output of the AGC amplifier or the output of the subtracter is selected and applied to a matched filter to which a decision feedback equalizer is coupled. In a modified embodiment, the transmit signal from a single source is transmitted over multipath fading channels, resulting in the reception of first and second diversity channel signals which are normalized to constant-amplitude signals whose predominant components are then phase-and-amplitude aligned with each other through feedback loops including an AGC amplifier. Correlations between the predominant components in the first diversity channels and the output of the AGC amplifier are detected and multiplied with the output of the AGC amplifier, combined in respective subtracters with the diversity channel signals for coupling to respective matched filters whose outputs are diversity-combined together for coupling to a decision feedback equalizer. In a further modification, the output of the AGC amplifier is combined with the phase-and-amplitude aligned signals by the subtracters for coupling to the matched filters.

Abstract: An imagery data mechanism for controllably merging separate, digitally formatted and arbitrarily shaped images eliminates overlap-edge artifacts by gradually blending a paste image (40) along its border (44) with a base image (30), regardless of the shape of the paste image. The mechanism employs a 'feathering' window (50) containing a plurality of neighboring pixel locations over which the pixel values of the paste image are controllably modified as to their transparency to achieve a tapered blending of the two images. Whether the data value for any pixel within the display is to be modified from a given database value will depend upon whether or not that pixel location is both within the paste image and a prescribed distance to the border (44) of the paste image. If the pixel location is not part of the image, it is effectively masked, so that not only does feathering not take place, but neither the base image nor the paste image contributes to its data value.

Abstract: 2.1 In known test devices which have a receiving part and an interlocking device, both components are permanently connected to one another. In practice, only some of a large number of test devices are in each case used at the same time so that the remaining interlocking devices, which are relatively expensive to produce, remain unused. It is the object of the invention to provide for better utilisation of the test devices, particularly the interlocking units in order to lower the costs. 2.2 For this purpose, it is provided that the interlocking device (3) is detachably connected to the receiving part (1), both the interlocking device (3) and the receiving part (1) exhibiting mutually corresponding holding means by means of which the interlocking device (3) can be fixed at the receiving part (1). 2.3 It is now possible to detach the interlocking devices from the receiving parts which are currently not being used, the interlocking devices then being connected to the receiving parts for which a use is planned. It is now no longer necessary to provide each test device with interlocking devices, which results in considerable cost savings. <IMAGE>

Abstract: An electrophotographic printing machine is provided with a photoreceptor drum (1) including a photosensitive layer (1 a) formed on a surface of an electrically conductive base (16), a contact charger (9) in contact with the photosensitive layer (1a) for charging the photosensitive layer (1a) by applying thereto a DC voltage, and a voltage drop detecting circuit (40) for outputting a detecting signal when the voltage has dropped below a reference voltage. When a defect exists such as a pin hole on the photosensitive layer (1a), the voltage being applied to the photosensitive layer (1 a) of the contact charger (9) drops. In this state, a detecting signal is output to a controller (21) from the voltage drop detecting circuit (40). When the controller (21) receives the detecting signal, the controller (21) signals to stop the operation of the entire device, and signals a display (36) to display a message indicating to exchange the photoreceptor drum (1), i.e. the image forming process will not be continued. Thus, the contact charger can be effectively prevented from breaking down.

Abstract: A cardiac pacemaker signal processing circuit adapted to obtain an evoked ECG signal. The circuit senses the electrical signals of the ring and tip electrodes in the unipolar mode from the bipolar lead after the electrical pacing stimulus has been applied to contract the ventricle of the heart. The residual oppositely polarized potentials at the ring and tip electrode, as well as the sensed evoked ECG signals, are added together to cancel out the opposing residual potentials, but to add the common polarized ECG signal. Thus, a high quality evoked ECG signal is obtained, free of the residual potentials, and subsequently utilized by R-wave detection circuits for sensing the QRS complex. The circuit includes compensating signal processing circuits to provide time domain signal processing weighting functions to match exponential time delay of the tip and ring electrodes, and includes amplitude adjusting compensation as well. Thus, the absolute amplitudes of the opposite polarized residual potentials will be adjusted to be equal, are summed, and canceled or nulled at the appropriate time in the time domain. Both biphasic and triphasic pace pulse techniques are not required, the pace pulse amplitude can be reduced to extend the battery life of the pacemaker. Further, the post pace re-charging cycle is only interrupted and undertaken passively to, again, reduce current drain on the battery. Classic R-wave detection circuits are adaptable to the signal processing circuit of the present invention.
