  • Patent number: 5345587
    Abstract: A system for managing an assemblage of entities. The entities interface within the assemblage for control of primary information handling functions and further interface with the system to permit the carrying out of management functions. The system includes management modules adapted to carry out management functions by independently interpreting and executing commands, a kernel including a table of dispatch pointers for directing the commands to the respective modules in which they are to be interpreted and executed, and an enroller for enrolling new modules into the system by adding further pointers to the table.

  • Patent number: 5093842
    Abstract: In a digital data recovery receiver, an optimal (in the Maximum likelihood sense) estimate of Es/No (dB) is obtained by the following mechanism. First, over a prescribed symbol span of N symbols, for each of 2.sup.B-1 -1 quantization bins, respectively associated with 2.sup.B-1 threshold levels used by a B-bit resolution analog-to-digital converter to digitize a received signal, the number of times that the received signal is quantized with respect to that level is counted. Each count total is divided by the number N of symbols in the span, to obtain plural ratios, respectively representative of probalities of symbol pseudo error rate over the symbol span. Using these ratios, respective Es/No (dB) values are derived from stored pseudo error relationships, each of which is associated with a respective one of the 2.sup.B-1 -1 quantization bins and defines the probability of symbol error rate in terms of Es/No (dB).

  • Patent number: 4896369
    Abstract: The possibility of overload (saturation-lockup) condition of an ALPC satellite communication network is avoided by a scheme that grants network entry (allocates TWT power) to each link one at a time. As each link is granted entry into the network, the corresponding TWT probability density function is computed and then integrated to obtain a TWT cumulative distribution function. The required rain margin M.sub.r for a specified availability is determined from the cumulative margin. The computed margin M.sub.r is set equal to the initial satellite TWT operating point change (multiplicative factor) MR.sub.1 due to rain fade, MF.sub.1 =M.sub.r to ensure that network stability considerations and rain fades equally constrain network performance. This result is then used to compute the value of the corresponding multiplicative factor MF.sub.2.

  • Patent number: 4684955
    Abstract: To measure the figure of merit (G/T) and beam radial pointing error of a satellite earth station multiple Y-factor measurement are taken using a "drift cut" procedure and then these measurements are processed using a maximum likelihood estimate (MLE) algorithm. For carrying out the "drift cut" measurement process, the earth terminal's antenna is positioned such that the antenna beam intersects the path of the apparent star motion with a predetermined declination offset and ahead of the current star position. As the star position approaches the stationary antenna beam position, power measurements uniformly spaced in time are recorded. These power measurement "samples" are then divided by the "cold sky" power measurement to obtain corresponding Y-factor measurements. To eliminate the problem of antenna pointing error and star ephemeris error, multiple drift cuts are carried out, each offset in declination by a different amount from the estimate star declination, to produce a matrix of Y-factor values.

  • Patent number: 4617951
    Abstract: Device for concealing and locking in place a weapon such as in conjunction with an umbrella wherein the weapon can be unlocked and withdrawn at will. The weapon locking device is operated by manually releasing spring-biased locking pins which are frictionally interlocked with a portion of the weapon when it is disposed in its locked position.

  • Patent number: 4202146
    Abstract: A factory-constructed module is provided having lower and middle dwelling compartments, a storage compartment, and provision for on-site completion of a third dwelling compartment to produce a split-level residential house. The module is transportable on the highways as a trailered unit having a maximum height compatible with public highway regulations. The module constitutes a major portion of the completed split-level house and contains substantially all the plumbing and electrical wiring required by said house, including electric service receptacles installed in the floor of said third dwelling compartment.
