摘要： A method of and an apparatus for magneto-resistively detecting information in a cross-tie memory system is disclosed. The detector includes a first conductive element, which is the terminating portion of an electrically-conducting wide-narrow edged propagating drive line, and second and third conductive elements that are serially aligned along a magnetic, serrated-edged data track, which three conductive elements form two gaps therebetween. The two gaps are oriented along the data track at respective narrow portions, a first narrow portion which may support a cross-tie but which second narrow portion will not support a cross-tie. A differential sense amplifier is coupled across the two gaps using the second narrow portion as a reference segment to differentially detect the presence vel non of a cross-tie in the first narrow portion.

摘要： A method of and an apparatus for counting is disclosed. The counter includes a generator of cross-tie, Bloch-line pairs and a shift register of N stages or memory cells along which the cross-tie, Bloch-line pairs are propagated or replicated into a detector. The method includes coupling a series of bipolar push-nucleate replicate signals, each one of which produces a cross-tie, Bloch-line pair in the adjacent downstream memory cell along the shift register. When the shift register is filled, a cross-tie will appear in the detector. This provides an output signal indicating that the N memory cells have been filled by the N replicate signals.

摘要： An antenna unit for measuring the velocity of a flowing material by the Doppler effect is particularly suited for use where only a limited space is available. The antenna unit comprises a support block having first and second surfaces disposed at an acute angle (optimally 45.degree.) relative to each other. A printed circuit antenna card having thereon a high gain antenna comprising a phased array of antenna elements is mounted to the second surface and radiates microwave energy toward the first surface. A plate having an opening therein is disposed adjacent the first surface, the plate being made of a material which absorbs radiated energy incident thereon. The support block is provided with a recess for receiving an absorber wedge which absorbs the energy radiated in near side lobes. The absorber wedge and plate shape the radiation pattern so that energy radiated by the antenna intercepts the material at an angle of 45.degree..+-.15.degree. when the first surface is disposed parallel to the axis of flow.

摘要： A pair of GPS receivers A and B which are constructed in the form of the receiver antenna combinations with receivers/antenna combinations which have been associated as ground-planes that extend beyond them. They are arranged such that the lower surface of the ground-plane of one receiver is adjacent to an RF absorber sheet, and the bottom of the RF absorber sheet is placed from the top of the second GPS receiver. This structure allows for the mask angle of the GPS receiver B to be matched to the mask angle of the GPS receiver A. When the normal path signal received by GPS receiver A becomes so large that it interferes with the direct signal to an unsatisfactory degree, reception is switched to GPS receiver B which senses only multi-path signals, but which allows the lock of the receiver pair combination to be maintained.

摘要： A sine wave oscillator provides an input signal to a step-recovery diode (SRD). The SRD produces a wideband series of harmonics of the frequency of the sine wave oscillator that are represented as "lines" in a power r.f. frequency plot. The output of the SRD is supplied to one or more bandpass filters or lowpass filters which provide selection windows so that only a specified number of harmonic lines are passed within a selection window. These specified harmonic lines are then coupled to one or more high speed input switches which are coupled to one or more high speed selection switches. The high speed selection switches are each coupled to a separate bandpass filter that is tuned to a different bandpass frequency range. Each bandpass filter corresponds to one or to several adjacent lines of the selection windows. The selection switches are connected so that various ones of them may be turned on to form either selective parallel or serial combinations, or even simultaneous parallel/serial compositions, of the frequency line components under the control of a digital switch controller. The output of the bandpass channel filters are coupled to a broadband output r.f. amplifier so chat transmission of the desired output signal may be made from the amplifier either over a wire or by wireless transmission. An amplitude level controller for limiting the amplitudes of selected frequency lines and a phase modulator for phase-modulating the output frequency line components are optional features.

摘要： A microwave grain monitor determines grain density and moisture content without measuring the phase shift of the measurement signal in passing through the grain. A set of grain coefficients is determined and stored in a non-volatile memory. A microwave measurement signal is transmitted through the grain and the ambient temperature is sensed. The grain density and moisture content are determined from the attenuation of the measurement signal in passing through the grain, the sensed temperature and the set of grain coefficients.

摘要： A monitor for measuring the moisture content of grain comprises an AC signal source for transmitting a measurement signal along a measurement signal path that includes a sensor region in which grain may, or may not, be present, and an analyzer for determining the attenuation of the measurement signal along the path, the analyzer producing an indication of the moisture content of grain in the sensor region that is dependent on the attenuation. A simulator is provided to permit calibration, testing, maintenance and/or demonstration of the monitor without the requirement of grain in the sensor region. The simulator includes a programmable attenuator that is selectively electrically inserted in the measurement signal path and a control circuit for controlling the attenuator so that the measurement signal is attenuated and the analyzer produces an indication of grain moisture content even though no grain is present in the sensor region. The attenuator may be a PIN diode or a programmable capacitor.

摘要： In a grain harvester having apparatus for measuring the moisture content of grain by directing a radio frequency signal along a measurement signal path through the grain and determining the moisture content from the phase shift and attenuation experienced by the measurement signal, calibration apparatus is provided for calibrating the moisture measurement apparatus without interrupting the grain harvesting operation. An attenuator, calibrated to a traceable standard, is selectively inserted into the measurement signal path to produce an expected attenuation of the measurement signal. The actual attenuation resulting from the insertion of the attenuator is compared with the expected attenuation and the difference is used to derive a control voltage for controlling the gain of the measurement signal path.

摘要： A broken tine detector for agricultural machines is provided for machines such as balers and forage harvesters. The tines form a first plate of a capacitor which rotates about the axis of a reel. The second plate of the capacitor may be provided by a back-plate which is located at the front of an agricultural machine adjacent to the ends of the tines and which is connected to machine ground. An alternate embodiment of the invention is devised by utilizing conductive strips on a tine guard. Each of the conductive strips may be utilized to form the second plate of the capacitor. The row of tines pass through individual slots in the tine guard so that a particular row in which the tine is broken may be detected. When a tine is broken the total capacitance between the tines and the back-plate will change and will be detected, and an indication will be supplied to an operator so that the operator may stop the machine and remove the tines.
