IPC: H04L5/16

Abstract: A feature negotiation protocol for synchronous operation and a dynamically adjustable retraining sequence. An originating modem, after completing conventional or standard handshaking sequences, sends a list of desired features to an answering modem. The answering modem either concurs with the desired features, if they are all supported, or sends, back to the originating modem, a list of those features which are supported by the answering modem. After the end of a negotiation time-out period, both modems begin operation using the features which are common to both modems or by using default (standard) features for operation. If the adjustable duration retraining sequence is selected then each modem will measure the elapsed time since the end of its last transmission and, at the beginning of its next transmission, send a retraining sequence which is dependent upon this elapsed time. Likewise, each modem will measure the amount of elapsed time since the end of its last reception and expect to receive a retraining sequence which is dependent upon this elapsed time. The adjustable duration retraining sequence generally operates to reduce the total retraining sequence and thereby increases the data throughput rate. The result is a modem which has enhanced feature negotiation capabilities and also a higher data throughput rate.

Abstract: A single-chip microcomputer comprises a logical circuit (21), a batch ultraviolet erasure type non-­volatile memory (22), and an electrically writable/­erasable non-volatile memory (23), and the logical cir­cuit (21), the batch ultraviolet erasure type non-­volatile memory (22) and the electrically writable/­erasable non-volatile memory (23) are integrated on a single semiconductor chip (20). A program necessary for data processing in the single-chip microcomputer is stored in the batch ultraviolet erasure type non-­volatile memory (22), and various data units are stored in the electrically writable/erasable non-volatile memory (23). Thus, the program can be easily rewritten, and data erasure due to a power supply abnormality can be prevented.

Abstract: Method and apparatus for playing an information recording medium carrying a plurality of music pieces and playing time information representing a playing time required for playing each of the plurality of music pieces. The plurality of music pieces are selected in order and a computing process is executed for adding up the playing time of each of the selected music pieces. Then, a provisional combination is produced by editing the selected music pieces excluding one of the selected musical programs when the total playing time obtained by the computing process exceeds a time period previously designated. Furthermore, a combination whose total playing time is the nearest to but shorter than the designated time period is derived by alternately replacing each of the music pieces in the provisional combination with each of music pieces other than the music pieces in the provisional combination. The derived combination is finally determined to be a playing program.

Abstract: The invention relates to an apparatus and method for computing in real-time jet engine net thrust, based on the previously known method of calculating gross thrust. Real-­time gross and net thrust are essential requirements for the calculation of the in-flight measured drag polar, lift curve, and aircraft specific excess power. From these elements, many other types of aeroperformance measurements are computed and analyzed. This gives an immediate postmaneuver assessment of data quality and maneuver technique, thus increasing the productivity of a flight program.

Abstract: An apparatus for detecting moving and unmoving regions in a moving image includes three memories for storing differentiation results of respective pixels in an x component, a y component, and a time component from two moving image data which are temporally successive. A first calculator reads out values of pixels near respective pixels in arbitrary two of the three memories, and calculates all quantities of multiplication/addition between the pixels. A second calculator calculates a value equivalent to a covariance determinant of vectors of an x component, a y component, and a time component from six results of the multiplication/addition. A third calculator calculates a multiplication between a time differentiation energy and a square of a spatial differentiation energy from results of the calculation of the second calculator and the pixel data values stored in the memories. A judgment device calculates a ratio of a result of an addition between an output data from the third calculator and an error energy.

Abstract: Method and apparatus are disclosed for electric discharge machining of workpieces on a mass production basis with adaptive feedback control to achieve accurate machining of a feature to a specified size. After machining a feature, it is measured to obtain a value which represents its size. An EDM process parameter is adjusted in accordance with the measurement value so that the next feature will be machined with the size closer to the specified size. Multiple features are machined in succession and the measurement values of successive features are analyzed to determine the trend of change of the values with respect to the specified size. The parameter, such as spark energy, is adjusted in a sense which tends to cause the succeeding features to be machined more accurately to the specified size.

Abstract: The invention relates to a circuit arrangement for the power supply and central control of a plurality of electrically driven actuators which serve to adjust the sitting position of vehicle seats of a vehicle seating arrangement and can be optionally switched on for individual seat adjustment by means of actuation switches arranged on the vehicle seat. In order to avoid load peaks due to uncontrolled simultaneous switching on of too many actuators, the power supply for the actuation switches is provided via a separate control line which is switched off when the load current flowing through the sum of the actuators which are simultaneously switched on exceeds a predetermined value. Additional switching relays which, when the actuators are switched on, apply DC voltage to the actuation switches independently of the control line for the duration of the activation of the actuator, ensure that when the control line is switched off running actuators are not switched off before the end of their desired adjustment movement. <IMAGE>

Abstract: A ladder-type encoding circuit is described for use with a keyboard interface, especially for use with the input/output pins of a single chip keyboard interface (111). The circuit is connected to the input/output pins by lines (1-21) used both for scanning and for sensing. The lines are arranged so that they run in a generally parallel direction and they then cross over the other lines so that the crossover points may be connected electrically by the depressing of keys. During scanning, one of the lines is set to a particular logic state with the remaining lines at a different logic state and the remaining lines sensed to detect the depressing of keys corresponding to crossover points between the lines scanned and the line set to a particular logic state. The ladder-type encoding circuit fully utilizes the capability of the input/output pins of the interface chip and reduces the number of pins required for sensing the depression of keys.
