摘要： This invention relates to a system for simulating a power plant synchroscope in which a digital computer supplies the information which indicates when two alternators are, or are not, in synchronism. Digital words are supplied by the computer to two separate registers whose parallel outputs are applied to the inputs of two separate frequency multipliers, one for each register. A single oscillator supplies its output to the second inputs of both of the multiplier, and the frequency of the oscillator is therein multiplied by the value of the words from the computer. The outputs from the two multipliers are supplied to two separate channels, one representing each of the two alternators. The square waves in each channel are converted into sine waves which are then applied to the incoming and running windings of a standard synchroscope. In addition, the information in the two channels is applied to the inputs of a phase difference detector which produces a digital phase difference.

摘要： A branch prediction method and system are provided that accurately predict a branch condition early in an instruction pipeline of a data processing system. By accurately predicting the branch condition, the correct target instruction can be fetched early, thereby avoiding many of the inefficiencies associated with branch mispredictions. To accurately predict if a branch condition is satisfied, one or more pre-calculated status bits are stored along with a digital value that is read by the conditional branch instruction to determine if the branch condition is satisfied. By including such a status bit, the condition of the conditional branch instruction may be immediately determined, without waiting for the instruction to be processed by an arithmetic unit or the like in a subsequent pipeline stage.

摘要： This disclosure describes apparatus for generating electrical signals which simulate the signals actually used by most sonar systems to indicate direction from which the sounds are received. In many passive sonar systems, arrays of hydrophones receive underwater signals from a number of sources. To indicate the direction of the sources from the receivers, the signals are manipulated so that they form, in effect, an axis along which the source of maximum amplitude lies. The equipment for performing this operation is contained in most sonar systems, and the simulation of such equipment is an expensive one. Therefore, this apparatus operates under the control of a simulation computer to generate signals which have the direction charactertistics of signals received by hydrophone arrays and which have been formed into two theoretical beams, one on each side of the axis of maximum amplitude. The apparatus of this invention includes beamformers for each of the sound sources to be simulated, all under the control of the computer.

摘要： Apparatus including a plurality of droplet ejection devices, an electric source and a controller. Each droplet ejection device includes a fluid chamber having an ejection nozzle, an electrically actuated displacement device associated with the chamber, and a switch having an input connected to the electric source, an output connected to the electrically actuated displacement device, and a control signal input that is controlled by the controller to control whether the input (and thus the electric source) is connected to the output (and thus the electrically actuated device). The electrically actuated displacement device moves between a displaced position and an undisplaced position to change the volume of the chamber as a capacitance associated with the electrically actuated displacement device changes in charge between an actuated condition and an unactuated condition. The controller provides respective charge control signals to respective control signal inputs to control the extent of change in charge on respective capacitances by the time that the respective switch connects the electrical signal to the respective electrically actuated displacement device.
