Abstract: A logical comb filter comprises a logic decision section (16, 17) for making logical decisions on the selection of signals and a signal generating section for generating signals to be selected according to the logical decisions. In the signal generating section, a band-pass filter (5) extracts from the input of a composite video signal a signal component centring on a colour sub-carrier frequency, and first and second delay lines (7, 9) generate three line signals based on an inverted output of the band-pass filter (5). A first mean level calculator (11, 13) calculates the mean level between the main signal and a first delay signal obtained as the inverted output of the first delay line (7), and a second mean level calculator (12, 15) calculates the mean level between the first delay signal and a second delay signal obtained as the inverted output of the second delay line (9). One of the output signals and the first delay signal is then selected by a changeover means (14).

Abstract: Transmission line groups consisting of a plurality of loop-like transmission routes (1...5, 10...50, 100...500) are mutually connected via transmission controllers and are arranged in a two- or three-dimensional space. Processing units are thus connected as a homogeneous network in matrix or mesh form by means of the loop-like transmission routes. The transmission controllers corresponding to the nodes (11...51) of the network have a communication management function such that they send the data without grasping the situation on the transmission routes, independently check the trouble between the adjacent transmission controllers, and specify the position of trouble. A communication network system such as a high local area network (LAN) or the like can be realized.

Abstract: A 1-bit token ring arbitration architecture where a plurality of chips which require access to a shared bus are coupled together in a ring is disclosed. Each chip receives an arbitration in signal from the preceding member of the ring which is used to receive the token. Each chip transmits an arbitration out signal to the following member of the ring to send the token to the following member. In the preferred embodiment, the token appears as a 1 cycle active low pulse. An error signal notifies all the bus participants that a ring error has been detected. Preferably, the number of cycles the error signal is held active, the more severe the error. A request of bus (ROB) signal notifies the chip holding the token that another bus member needs to use the bus. The ROB signal allows the current holder of the token to maintain control of the bus if it has further processing on the bus as long as no other bus member needs the bus. A first timer is called a Token Hold Timer may be included in a ring member which defines how long a the member can hold on to the token after receiving notification on the ROB line that another bus participant wants the bus. A second timer may be included in a ring member to define the maximum time between the release of the token to return of the token by a given processor. It is used as a means to detect whether a lost token condition exists on the ring.

Abstract: A method and apparatus for video imaging of a tire ground contact patch or tire footprint is presented. A digitized image of the footprint is generated as an array of pixels. Each pixel is attributed a binary value of one or zero, to present a two-valued image. Contact areas within the image are attributed a first value, while void or noncontact areas are attributed a second value. The image is then dilated and eroded in an appropriate sequence to eliminate all white pixels from the image and to eliminate surface anomalies or the like which are not of interest in the tire analysis. An image of the footprint, accurate in size and dimensions, is thereby generated and, from such footprint, total area, contact area, and void area can be determined, as well as measurements of width, center line length, and other desired lengths at various lateral width locations. This data may be used to analyze the tire construction, operation, noise generation, and performance.

Abstract: The crusher has crushing hammers (5) which rotate on a circular path. The material for crushing passes into the annular crushing zone via a distributor plate (10) and is taken hold of there by the crushing hammers (5) and comminuted. In this process, it is thrown tangentially outwards against an impact zone (6). Here, it strikes against impact plates (12) and is further comminuted. In this way, the material for crushing which is distributed over the entire circumference is acted on twice by means of a hard jolt. In this way, a throughput which is increased for the size of the mill can be achieved with optimum crushing effect. <IMAGE>

Abstract: Data from long range aids such as the global positioning system (GPS) and an inertial navigation system (INS) and short range aids such as a microwave londing system (MLS) are used to smoothly and automatically transition an aircraft from the long range aids to the short range aids. During cruise a Kalman filter (70) combines data from the global positioning system and the inertial navigation system to provide accurate enroute information. When the aircraft arrives in the vicinity of the airport and begins to acquire (70) data from the microwave landing system, the Kalman filter (70) is calibrated with the MLS data to permit precision landing with GPS/INS data alone in case the MLS system subsequently fails. In addition, navigation information begins to be derived from a weighted sum of the GPS/INS and MLS data, the weighting being determined by distance from the airport. In a first region farthest from the airport, the GPS/INS data is given a 1.0 weighting factor; and in a second region nearest the airport, the MLS data is given a 1.0 weighting factor. In a third region intermediate the first and second regions, the GPS/INS data and MLS data are proportionately and complementarily weighted as a function of the distance from the airport. If the MLS system fails, the weighting system (76, 78, 80) is disabled (84) and navigation data is again derived from the GPS/INS combination. In addition, the data from both systems are monitored (74), and a cockpit alarm is sounded if the data diverged beyond a specific amount. The Kalman filter (70) supplies a weighting system comprising two weighting devices (76, 78), one (76) of which weights the MLS data, and the other (78) the GPS/INS combination data. The outputs of these devices (76, 78) are summed (80) and supplied to one terminal of a switch (84) for selecting between the weighting system (76, 78, 80) and the Kalman filter (70).

Abstract: An adaptive paging system includes a paging terminal that is operable to receive paging signals and transmit them up to a satellite (28) and down through a downlink (312) to stick locations (314), (316), (318), (320) and (322). Each of the sticks (314) - (322) is associated with a given locale (324), (326), (328), (330) and (332). The sticks are operable in a simulcast mode and also in a cellular mode. In the cellular mode, each of the sticks (314) - (322) is operable to receive a separate message that is distinct from the other cells. Pagers (36), having a known location at any of the locales (324) - (332) can then be selectively addressed and data transferred thereto. To prevent interference between adjacent RF locales, adjacent cells are not turned on during transmission to select cells in the cellular mode. These can be turned on at a different time. Orthogonal coding can be utilized such that adjacent cells can be turned on, thus increasing throughput.

Abstract: A process for separating by pressure swing adsorption a gas mixture comprising a first component which is adsorbed in preference to the other component or components of the mixture (for example a mixture of methane and oxygen which contains methane at a concentration greater then the upper explosive gas mixture limit is separated without producing an explosive gas mixture) includes the steps of feeding the gas mixture into an adsorber which contains an adsorbent which preferentially adsorbs methane until the desired production pressure is attained in the adsorber and then stopping the flow of feed gas into the adsorber and charging methane product gas at the production pressure cocurrently into the adsorber while simultaneously withdrawing nonadsorbed product gas from the nonadsorbed product end of the adsorber. The desorbed product stream is enriched in methane relative to the feed stream and the concentration of methane in the nonadsorbed product stream is less than the minimum flammable mixture concentration.

Abstract: In a diagram drawing apparatus when a figure in the diagram is enlarged or reduced, data at a line having one end tangent to the figure is automatically modified according to the enlargement or reduction of the figure. When a figure, for example, a rectangle of a flowchart representing a processing step, to which a straight line indicative of a flow of the flowchart is connected, is enlarged, data denoting the line end coordinates (end point coordinates) of the straight line tangent to the rectangle and the other line end coordinates (start point coordinates) thereof are read out from a diagram data memory (14) and then stored in a data memory (15). After that, coordinates of an intersection point between the enlarged rectangle and the straight line are calculated and stored in the data memory (15). The end point coordinates of the straight line stored in the diagram data memory (14) are changed so as to coincide with the intersection point coordinates, thereby drawing a new straight line connected to the changed start point coordinates in the enlarged rectangle.
