International Classification:

C12H 100

US Classification:

426 11, 426489, 426484, 426473, 426519, 4352911

Abstract:

A wine fermentation device for fermenting wine, and skins, seeds and stems which form a cap. The device includes a tank having cylindrical walls, an axis and a bottom. One or more optional interior baffles may be provided. At least one drain is located at or near the tank bottom. The device includes at least one impeller, and in a preferred embodiment two impellers, each impeller having a plurality of blades to radially and axially move the cap during fermentation and to blend the cap with liquid to permit draining of the cap (or pomace) through the drain.

Appl. No.:

11/258706

Inventors:

Guy Thomas Varty - Woodland Hills CA, US
Anthony Matthews - Santa Barbara CA, US

International Classification:

G01C 19/00

US Classification:

33321, 7350412

Abstract:

Apparatus, systems, and methods to control a plurality of gyroscopes utilizing intermediate frequencies are disclosed. The gyroscopes are configured to operate at the same pre-determined intermediate frequency. To accomplish this, the natural frequency of each gyroscope is determined, and a reference signal is added to the output signal of its respective gyroscope such that the sum of the natural frequency and the reference signal frequency equals the pre-determined intermediate frequency. The output signal from each gyroscope is transmitted to a common inertial data processor, and the inertial data processor outputs a directional signal. The directional signal includes a representation of angles from an X-axis, a Y-axis, and a Z-axis. Since each signal output by the gyroscopes has the same frequency, the loss of data is decreased and the accuracy of the data increased.

International Classification:

G01P 15/14

US Classification:

073504020

Abstract:

Apparatus, systems, and methods to control the frequency of a plurality of gyroscopes are disclosed. The gyroscopes are configured such that each individual gyroscope operates independently of one another and at the same pre-determined frequency. To accomplish this, the natural frequency of each gyroscope is determined, and a reference signal is added to the output signal of its respective gyroscope such that the sum of the natural frequency and the reference signal frequency equals the pre-determined frequency. Thus, each individual gyroscope, though it may include its own individual natural frequency, operates autonomously at the pre-determined frequency.

Appl. No.:

7/447560

J. Scott Darling - Chatsworth CA

Assignee:

Litton Systems, Inc. - Woodland Hills CA

International Classification:

G01B 902

US Classification:

356350

Abstract:

Apparatus and methods are disclosed for the time division multiplexing of fiberoptic gyros to reduce the amount of control electronics required. Each of a plurality of gyros is sampled at a rate of n. tau. , where. tau. is the gyro optical transit time and n is an integer. The sampled signal is fed to a digital signal processor (DSP) for processing and used to form a rate feedback signal. The rate feedback signal is converted to analog form to drive the phase modulator drive of each gyro. In preferred embodiments the multiplexed sample rate is at least ten times the bandwidth of the gyros. The rate data can be filtered and output by the DSP and the DSP can integrate the rate data to give angle data. The use of precision analog circuits is avoided.

Assignee:

Litton Systems, Inc. - Beverly Hills CA

International Classification:

G01C 1964

US Classification:

356350

Abstract:

The use of a high speed moving average filter is shown to filter high speed errors, including white noise in angle and quantization errors, from the output data of a ring laser gyro while it is being tested. The filtered data permits investigation of the lower speed, random walk in angle error of the gyro being tested. For best results, several moving average filters are connected in series.

International Classification:

H01S 310

US Classification:

356350

Abstract:

A ring laser gyro having a cavity with at least one transducer-actuated mirror is controlled to conform to a preselected model of cavity operation. Control is accomplished by sampling cavity data, comparing the data to the model to generate an error signal, and controlling the mirror according to the error signal. In a preferred embodiment, at least two mirrors are dithered and the model defines an optimal amplitude of mirror dither at which theoretical lock-in error is zero. In another preferred embodiment, the sampled data corresponds to laser intensity within the cavity and the model defines an optimal intensity displaced from the maximum within an operating mode of the cavity. The model may define a plurality of operating modes of the cavity, ranked according to gyro performance for different values of a preselected environmental condition. The environmental condition is then sensed on an ongoing basis and used to select an optimal mode.
