摘要： An arrangement using sensing coils for obtaining flux rate of change information in a magnetic circuit. The arrangement can be used for vibration attenuation in a magnetic forcer system. Active (electric powered) circuitry is used to implement closed loop control of flux rate. The control loop is "broadband" since a broad range of vibration frequencies are attenuated. The arrangement can be applied to magnetic forcer/suspension systems in which vibrations due to magnetic mechanical/magnetic runouts, system mechanical resonances, or external vibration sources are present. The arrangement is particularly applicable for systems with a large number of varying vibration frequencies.

摘要： A current regulator for a laser tube used in a ring laser gyroscope includes a ballast resistor coupled to the laser tube's anode, an output for the current, such as a current sensing resistor, a current source coupled between the ballast resistor and the output, a control circuit that establishes the amount of current flow through the current regulator, and a voltage divider that senses the voltage across the current source. The current source includes two transistors coupled in series and the voltage divider generates a voltage level that is half the sensed voltage differential and supplies the generated voltage level to one of the transistors so as to control the voltage drop across that transistor to be the same as the voltage drop across the other transistor. The current source may include more than two transistors in series and the voltage drops across the transistors are controlled to be the same.

摘要： A noise reducing thermal-electrically cooled photodetector for an Interferrometric Fiber Optic Gyro (IFOG) includes a photodiode that converts an optical power signal received from a coupler of the IFOG to an electrical compensation signal. The photodiode is in mechanical contact with one or more thermoelectric coolers (TEC) to lower an operating temperature of the photodiode. The photodetector also includes an amplifier circuit to amplify the electrical compensation signal. The amplifier circuit includes an operational amplifier having an input and an output, with a feedback resistor interposed between the input and output. The feedback resistor is also in mechanical contact with a TEC to lower an operating temperature of the feedback resistor. By reducing the operating temperature of the feedback resistor and the photodiode the thermal noise of the IFOG is reduced.
