Abstract: A system for distributing remote telephone traffic between a base station and remote antenna site is disclosed. The base station and remote antenna sites are connected via a cable television network. The base station receives from a public telephone network parallel channels of outbound voice signals for radio telephones operating within the cellular areas of the remote antenna sites. The base station will digitize each of these outbound telephone signals, and time compress them to fit in a transmit frame having the length of a standard channel transmit frame of a radio telephone system. The transmit frame is modulated on a subcarrier and applied to the cable television network. A plurality of remote sites are connected to the cable television network and receive and rebroadcast digitized voice signals to radio telephones operating within their cellular areas. Inbound serial channel data received from a radio telephone is inserted in a serial receive data frame along with other channel data received from other radio telephones operating in this cell. A second subcarrier is modulated with the receive data frame and applied to the cable television network for transmission upstream to the base station. The base station will demodulate the inbound receive frame and apply the digitized voice signals to the public telephone network to complete a telephone communication link between the radio telephones and public telephone network.

Abstract: A digital divider for dividing an M-bit dividend by a divisor 2 N  (M and N are respectively a natural number, and M≧N) is provided with an incremental unit for adding a value 1 to a first binary numeral consisting of a series of binary digits positioned at higher M-N places of the dividend to generate a second binary numeral, a logical OR gate for receiving binary digits positioned at lower N places of the dividend to judge whether or not at least one of the binary digits is "1" and outputting a judging signal, a logical AND gate for receiving both the judging signal and the binary digit of the most significant bit of the dividend. A selecting signal is output from the logical AND gate. The digital divider is further provided with an (M-N)-bit selector for receiving the first and second binary numerals to select one of the numerals according to the selecting signal. In cases where the dividend is negative and at least one of the binary digits is "1", the selecting signal is designated by the binary digit "1" so that the second binary numeral is selected by the selector as a quotient. In other cases, the selecting signal is designated by the binary digit "0" so that the first binary numeral is selected by the selector as a quotient

Abstract: A memory (20) has N BIAS  generators (63 and 73) coupled to the positive and negative power supply lines (61 and 62) at a point close to amplifiers (84 and 85) and address buffers (76) to insure that they all receive the same power supply voltage to prevent an impact on the access times of memory (20). A V CS  generator (65) is located close to power supply bonding pads (23 and 25) and to output buffers (77 and 78) to reduce the effects of power supply line noise on the noise margins. A V AREF  generator provides a reference voltage to the differential amplifiers of address buffers (75 and 76). Locating V AREF  generator (67) close to power supply bonding pads (23 and 25) insures that the reference voltage is always at the midpoint of the input logic swing.

Abstract: In a sweeping machine some debris may be thrown over the main sweeping brush and into the space behind it, so a recirculation flap is commonly provided behind the brush to recirculate such debris under the brush for re-sweeping. To be effective, such a flap must be mounted close to the surface being swept, and consequentially may be damaged by projections on the surface, such as, for example, speed bumps. An improved recirculation flap is disclosed which moves out of the way without sustaining damage when a speed bump or other projection is encountered and automatically returns to operating position when the sweeper has passed the projection.

Abstract: The present invention is based on the object of avoiding the described disadvantages of the conventional methods for producing colour enlargements. The metering colour exposure system bypasses the respective disadvantages of both methods since adjustable or replaceable filters and different exposure times for the different colours are bypassed. The light sources for the different colours are arranged separate from each other and cannot influence each other. In order to adjust the colour mixture necessary for exposing a print, the beam path of the different colours is covered by one of three diaphragms or by other suitable measures. The cross-section of the beam is thereby changed, the light is metered. In detail, the method based on the invention achieves the following advantages compared to conventional methods:   . no mutual influencing of individual colour filters, thereby reduction in the overall exposure time and higher throughput in the case of industrial photographic printers. . identical exposure time for the three colours and thereby bypassing of a colour distortion as a result of the long-term effect (Schwarzschild effect) or ultra-short effect. (Reciprocity law) . precise and simple colour guidance independently of different exposure times and exposure intervals . as a result of a comparative measurement method, independence of different photographic papers, chemicals and negatives.

Abstract: The present system and apparatus uses image processing to recognize objects within a scene. The system includes an illumination source for illuminating the scene. By controlling the illumination source, an image processing system can take a first digitize image of the scene with the object illuminated a higher level and a second digitized image with the object illuminated at a lower level. Using an algorithm, the object(s) image is segmented from a background image of the scene by a comparison of the two digitized images taken. A processed image (that can be used to characterize features) of the object(s) is then compared to stored reference images. The object is recognized when a match occurs. The system can recognize objects independent of size and number and can be trained to recognize objects that it was not originally programmed to recognize.

Abstract: An apparatus for forming sheet material assemblages includes a plurality of pockets which are movable past a plurality of sheet material feeders. Each of the pockets includes a sheet material support which is movable between any one of a plurality of closed positions and an open condition. When the sheet material support is in a closed position, it blocks the lower end portion of the pocket and supports sheet material in the pocket. When the sheet material support is in the open condition, it is ineffective to block the lower portion of the pocket so that the sheet material assemblage can move out of the pocket through the lower end portion of the pocket. An actuator is provided to move the sheet material support from the open condition to a closed position. The sheet material support is connected with side portions of the pocket by a four bar linkage. A clutch assembly in the four bar linkage is operable from an engaged condition to a disengaged condition to release the sheet material support for movement from a closed position.
