摘要： Destabilization of a gyro-stabilized platform (such as employed for mounting an antenna on-board a ship) resulting from uncompensated yaw or rotation of the platform in azimuth from a fixed reference orientation is prevented by employing a pair of counter-rotating gyros for each stabilized axis and caging gyros having a spin direction opposite to the direction of rotation of the platform.

摘要： A high-accuracy phase comparison system for noise-contaminated fixed-frequency input signals, such as Omega radionavigation signals, employs a pair of phaselock loops in which output pulses from a high-frequency oscillator are deleted at the frequency of a variable-frequency oscillator which is responsive to the detected phase difference between the associated input signal and an associated reference signal, thereby to provide a high-frequency intermediate signal which is frequency-divided to produce the reference signal continuously and free of noise. The relative phase of the input signals may be determined by phase-comparing the reference signals of the two phaselock loops or, to provide even higher precision, by phase-comparing the variable-frequency signals of the two loops.

摘要： A high-resolution apparatus and method provide direct digital measurement of electrical properties such as resistance, capacitance or inductance. An excitation signal derived from a high-frequency source is applied to a network containing an unknown device to produce a network output signal with an amplitude that corresponds to the electrical property to be measured. Amplitude variations in the network output signal are converted to corresponding phase variations in a third signal by adding the network output signal to a reference signal that is phase shifted by 90-degrees with respect to the excitation. The third signal is then applied to a phaselocked loop that employs the above-mentioned high-frequency source in combination with a pulse delete circuit to produce an output that multiplies phase information contained in the third signal by orders of magnitude. Conventional methods can then be used to measure the resulting greatly magnified phase changes corresponding to minute changes in the electrical properties of the device under test.

摘要： A method of and system of providing a realistic audiovisual representation at a remote location of a game occurring at a base location in which the base location and remote location are linked by a communications channel, including the steps of preparing a library of prerecorded video clips depicting events typically encountered in conducting a game, storing the library of the remote location, transmitting information as to the progress of a game from the base location to the remote location over the communication channel at the base location using the information to select appropriate video clips from the library that replicate the game, and presenting the selected video clips at the remote location to provide a realistic audiovisual representation.
