Abstract: A double tank milk supply system for providing a continuous supply of cool clean milk or milk products. While one tank provides milk products, the other tank is cleaned. The two tanks are individually cooled, and the washing and cooling cycles are automatically controlled via a data input and display device. Included is an automatic valve system configured to dispense milk product from the second tank when the first tank is empty, and to dispense milk product from the first tank when the second tank is empty. An automatic washing system automatically washes the first tank when the first tank is empty, and washes the second tank when the second tank is empty. Also included is an agitation system, which alternatingly agitates the milk product in the first or second tank. The double tank milk supply system provides uninterrupted cool, clean milk products 24/7/365, saving the farmer time and labor.

Abstract: To provide an improved non-additive mixer, a first mixer mixes first and second video signals according to a mixer control signal derived in a new way. The first and second video signals are applied, respectively, to first and second chrominance (blocking) filters. The resulting first and second luminance signals are applied, respectively, to first and second summing circuits, where offsets may be applied to either or both of them. The difference is then taken between the first offset luminance signal and the second offset luminance signal to produce a difference luminance signal. The difference luminance signal is then multiplied by a gain control signal to produce the mixer control signal. The mixer control signal can also be used to control a second mixer, thereby providing a channel for keying information that is non-additively mixed according to the luminance content of the video signal that the key information is associated with.

Abstract: A video effect is created with a video processing machine having a plurality of functions, each of which has a state that is selectively variable in response to change in an associated function parameter. The method comprises selecting a set of functions, specifying a starting keyframe containing a starting value for each of the parameters, specifying an ending keyframe containing ending values for the parameters associated with the functions of the selected set and vacancies for the other parameters associated with other functions, and specifying a number of video frames. The starting keyframe is used to place the machine in a starting state, in which each function has the status defined by the value of its associated parameter in the starting keyframe, and a first video frame is processed with the processing machine in the starting state.

Abstract: A pseudo-random pattern generator has modifiable feedback so that a variety of pseudo-random video patterns can be generated and used either directly, or after further manipulation, to control the mixing of two video sources. Control of a multiplexer allows a variety of pattern lengths to be selected by altering which stages of a shift register are supplied to a feedback exclusive-OR gate. Patterns with controllable granularity can be achieved by stretching each part of the noise pattern a selectable number of times along either or both axes. Horizontal stretching is achieved by clocking the shift register more slowly than the rate at which it is being read out. Vertical stretching is achieved by repeating the same pattern on each of a selectable number of consecutive lines. Varying the ratio of the stretching along the horizontal axis to the stretching along the vertical axis allows the aspect ratio of the grains of the pattern to be controlled.

Abstract: An adaptive rounder for avoiding truncation errors for digital video signal has a dither source that is modified by the bits of an integer portion of an input digital signal corresponding to the video signal. A dither signal from the dither source has a number of bits equal to a fractional portion of the input digital signal. The dither signal is added to the input digital signal and the result is truncated to produce an output digital signal having a number of bits equal to the integer portion.

The second mixer has a mix control input terminal connected to receive the second control signal as a mix control signal.

Abstract: A mix effects based switcher architecture provides for processing of video signals with associated key signals throughout, the mix effects (M/E) banks within the switcher outputting both a composited video signal and a composited key signal for use by subsequent M/E banks. The outputs of the M/E banks may be combined together before being input to an output M/E bank. The output M/E bank provides a layered video signal with associated composited key signal at the output of the switcher.

The digital mask signal is combined with the digital key signal to provide a modified digital key signal, and the input video signal is acted on in accordance with the modified key signal to provide an output video signal.

Abstract: A digital wipe generator has a digital waveform generator to generate X and Y digital waveforms from a composite sync signal. A digital wipe solid generator processes the X and Y digital waveforms to produce a digital wipe solid waveform. The wipe solid generator has a circle generator using a square root function which preshifts the sum of the squares prior to access to a look-up table, and then post shifts the output of the look-up table by one-half the amount of the preshift to produce a desired curve pattern for the digital wipe solid waveform. The digital wipe solid waveform is input to mixer circuits where it is processed to produce an anti-aliased key signal for mixing external video signals, the anti-aliasing being based upon an interpolation/decimation scheme using fractional bits of the digital wipe solid waveform. The output of the mixer circuits is a desired wipe transition.

Abstract: A first pair of input data words represent two adjacent pixels on a first line of a first field of a video signal in interlaced format, a second pair of input data words represent two adjacent pixels of a first line of a second field of the video signal, and a third pair of input data words represent two adjacent pixels of a second line of the second field. The first and second lines of the second field are adjacent lines in that field and the first line of the first field is between the first and second lines of the second field. The positions on their respective lines of the pixels represented by the second and third pairs of input data words correspond to the positions on the first line of the first field of the pixels represented by the first pair of input data words. The first, second and third pairs of data words are read from memory, and are processed by interpolating among them to generate an output data word.

Abstract: A small electrical fuze for use with an explosive projectile being subject to very high g forces both in the direction of and opposed to the line of flight. A lead charge is disposed in a barrel rotor whose axis of rotation is normal to the flight path for providing the safing and arming function. A system of controlling drive balls captured in shaped slots on the surface of the barrel rotor in cooperation with straight slots on an interior surface of a mounting cavity provide the necessary forces for a multiple step arming sequence in response to spin-induced forces on the fuze. These multiple step sequences include two direction reversals. A one-fourth wavelength shorted skirt surrounds the fed end of a monopole antenna to isolate the radio frequency currents thereon from the body of the projectile thereby improving the antenna pattern in the direction of trajectory.
