  • Patent number: 4063072
    Abstract: A method for operating an aircraft at the minimum total flying cost per unit of distance. The fuel cost per unit of distance and the flying time cost per unit of time are calculated at a first fuel flow setting and are added together to obtain a total flying time cost per unit distance. After a predetermined time interval, a second fuel flow setting is entered into the aircraft and a second total flying time cost per unit distance is calculated and compared to the first. The fuel flow setting is again adjusted in the direction of the minimum total flying time cost per unit of distance. This procedure is repeated until the minimum is found, and can be repeated thereafter at specific intervals to assure that the minimum is maintained.

  • Patent number: 4063073
    Abstract: A method and system of preventing collisions between aircraft comprising defining an imaginary airspace around the center of each aircraft, the airspace having a given radius (R) and height (H), and moving with and at the same velocity as the aircraft. An imaginary airspace having zero velocity is defined around objects of terrain and the parameters of each defined airspace are updated as the corresponding aircraft travels. The parameters of each aircraft defined airspace is compared one at a time with the parameters of all other defined airspaces within a discrete altitute band under predetermined criteria to determine whether there is an existing or future travel course conflict, and an indication is produced in the event such a conflict is determined.

  • Patent number: 4061908
    Abstract: The invention provides a compact test sequence for testing integrated memories. First, all storage positions are filled with the bit "0". Subsequently, in a given order of the addresses, the "0" bit written for each address is read; immmediately thereafter a "1" bit is written in those bit positions. The positions are again tested by reading the "1" bits. When the last address of the predetermined order is reached, the "1" is read in the same order for each address. Subsequently a "0" is written, which is finally tested by reading again. When the last address is reached, all addresses are read in the reverse order, and a "1" is written, which is tested again. When the first address is reached, all addresses are read, filled with a "0" and tested. This process may be repeated as many times as there are bits in the address. The significance of the address bits are modified to form the predetermined order, for example, by cyclic rotation.

  • Patent number: 4061903
    Abstract: An improvement in a digital coordinator of the type used for creating a background cycle defined by a series of control pulses repeatedly cycled between a first number, N.sub.1, and a second number, N.sub.2, with the time space between the N.sub.1 control pulse and the N.sub.2 control pulse being a background cycle length. This type of coordinator comprises a primary pulse counter means incremented by input counting pulses for creating one in a series of control pulses in response to a selected number of input counting pulses, wherein the input counting pulses have a selected frequency for determining the cycle speed of progression of the control pulses in successive count positions between the N.sub.1 control pulse and the N.sub.2 control pulse of a given background cycle, and shifting means for shifting the N.sub.1 control pulse with respect to time to correspond in time with a synchronization offset signal.

  • Patent number: 4053752
    Abstract: A virtually addressed multilevel mass storage system (MSS) has error recovery and definition procedures and apparatus for controlling and enabling recovery from error conditions in an upper storage level. A plurality of possible error conditions in an upper level gives rise to errors in destaging data signals to a lower level, plus possible overwriting good data with data in error. A first such error condition is a data error detected during a destage. A second such error condition is repeated upper-level equipment (not data) errors. Both errors make data integrity of the lower-level suspect. Corrective action for a plurality of errors includes coordination with a host computer, reconfiguration, destaging data in error after precautionary steps, and preserving data in error at the failing upper level unit which is used in virtual mode except for the portion yielding the error condition.

  • Patent number: 4051355
    Abstract: Apparatus and method are described wherein the average access time utilized for recovering stored data in a random access storage system is reduced. An access cycle is begun with the predetermined typical data bit delivery time known and with the knowledge of the worst case data bit delivery time. An output buffer is connected to a random access storage for receiving the data bits of an output message from the storage. The output buffer is gated to receive the data from the random access storage; the gate signal enables the output buffer to receive data bits over a predetermined time interval. The output buffer is connected to a data transmission means such as a bus, and is gated by a second signal to place the stored information on the bus. The second signal, the message gate signal, is timed to place the information stored in the output buffer on the bus during the period beginning with the typical data bit delivery time and ending after the worst case data bit delivery time.

  • Patent number: 4039814
    Abstract: An apparatus is provided for analyzing output signals of digital devices. The apparatus comprises a plurality of comparison registers which evaluate the digital output signals, each comparison register including rotary switches for decoding the output signals under analysis. Programming switches permit to generate a function signal through at least one output channel provided in each comparison register when the output signals and the decoded value of said register are in a predetermined relationship. The operations of all comparison registers are selectively controlled by means of a logic circuit. As a result, a function signal is issued by the comparison register through a given channel in accordance with a predetermined program set by the switches and under the control of the logic circuit means, whenever a predetermined relationship exists between the output signals from the digital device under analysis and the value decoded on the comparison register.

  • Patent number: RE29550
    Abstract: Apparatus for generating graphic symbols on a cathode-ray tube employs a beam control system which starts each of a plurality of parallel strokes required for each symbol at the bottom, using a programmed offset for symbols which extend below a baseline, and to otherwise move a symbol in the X and Y axes from a position routinely specified as spaced symbols are displayed in a line. The slope of the strokes for a symbol is controlled for italicizing the symbols by programming the relative magnitudes and signs of inputs to X and Y integrators which generate ramp signals added to symbol positioning signals. The beam is turned on and off during each stroke in response to a programmed and clocked bit stream of coded digital signals. The size of a symbol is controlled by programming the clock rate for the beam on-off control and the magnitudes of the inputs to the X and Y integrators.
