Abstract: A system includes one or more processors configured to determine a discharge rate associated with discharging material from a hauling machine. In some examples, the system receives sensor data associated with a crushing machine configured to receive the material. Based on the sensor data, the system determines the discharge rate, to optimize the efficiency of the crushing machine. In some examples, the system determines the discharge rate based on input by an operator via a user interface. In some examples, the system determines an angular rate at which to raise a bed of the hauling machine to cause the material to be discharged at the discharge rate. Based on a determination to discharge material, the system causes the bed to be raised at the angular rate to discharge material. In some examples, the system may update the discharge rate based on additional sensor data and/or an additional operator input.

Abstract: A system for synchronizing a target device to a cardiac cycle, including: (a) a target device that collects data or performs an operation that is to be timed to the cardiac cycle; (b) a signaling device that emits a signal indicating the occurrence of a cardiac contraction and/or ECG feature; and (c) a calibration device that determines the relationship of the signal from the signaling device to the actual cardiac cycle. In operation, the calibration device calculates a time offset between the timing of the cardiac contraction as determined by the signaling device and the timing of the cardiac contraction and/or ECG feature as determined by the calibration device, and then provides the time offset to the target device.

An output of the amplifier is coupled to a vertical deflection winding. A current sampling resistor is coupled to the first input via a first resistor. The second input is coupled via a second resistor to a terminal of the sampling resistor that is remote from the first resistor. The first and second resistors are matched resistors for providing differential driving.

Abstract: In a D.C. coupled vertical deflection circuit, an input sawtooth signal is coupled to an inverting input of a vertical deflection amplifier via a first resistor network. A D.C. voltage is coupled to a second input of the amplifier via a second resistor network for preventing the D.C. signal component from affecting the deflection current. To provide temperature compensation, for every resistor included in the first resistor network, there is included a corresponding resistor of equal value in the second resistor network.

Abstract: A television receiver is controlled as to the degree of vertical zoom via a deflection current ramp that varies in slope and which may be delayed to achieve panning. Due to the increased slope when zoomed, the deflection current and the electron beam complete a trace in less time than the normal vertical interval. The deflection current is maintained at one extreme or the other outside the trace interval, and the beam is blanked. A retrace signal generator coupled in a feedback loop with the power supply for the deflection circuit determines the midpoint of the blanking period and generates a fast retrace at or near the midpoint. The feedback loop is arranged to minimize the DC average current in the deflection winding by having a current source responsive to the DC average current for charging a timing ramp that triggers retrace upon reaching a threshold. The slope of the timing ramp varies with DC loading, thus advancing or retarding retrace to center retrace in the blanking interval.

Abstract: A differential amplifier formed by a pair of transistors couples a vertical sawtooth signal to an input side of a vertical deflection amplifier. Nonlinearity of the transistor pair provides S-correction in the vertical direction. The current in the transistor pair varies when vertical height is adjusted, in service operation, so that the nonlinearity changes. In a vertical shrink mode of operation, the amplitude of the sawtooth signal is reduced. The nonlinearity associated with a given level of the sawtooth signal that corresponds to a given vertical position in the vertical shrink mode is the same as that associated with the same level of the sawtooth signal in the vertical, non-shrink mode.

Abstract: A differential amplifier formed by a pair of transistor couples a vertical sawtooth signal to an input side of a vertical deflection amplifier. Nonlinearity of the transistor pair provides linearity or S-correction in the vertical direction. The amplitude of the sawtooth signal is adjusted by way of adjusting a vertical height control signal. To compensate for a change in the S-correction that is introduced by the amplitude adjustment, the vertical height control signal is coupled to the emitters of the transistor pairs for controlling the nonlinearity.

Abstract: A first voltage-to-current converter responsive to a picture height adjustment control signal generates a first current in a capacitor for producing a trace portion of a sawtooth signal in the capacitor having a rate of change that is adjustable in accordance with an adjustment of the control signal. A second voltage-to-current converter responsive to the control signal generates a second current in a resistor for producing a third signal that is adjustable in accordance with the control signal. The sawtooth and third signals are coupled via a differential amplifier to a vertical deflection winding to produce a vertical deflection current in accordance with a difference between the sawtooth and third signals such that picture height adjustment does not affect vertical centering.

Abstract: In a vertical sawtooth generator of a D.C. coupled vertical deflection circuit, a vertical deflection amplifier generates a sawtooth signal. Magnitudes of the sawtooth signal in first and second instants of its trace period are determined in accordance with first and second D.C. signals, respectively. The first and second D.C. signals are adjusted during service to control the raster height and the raster centering such that while the raster height is adjusted, raster centering is not significantly affected, and vice versa.

Abstract: In a vertical sync separator, a composite sync signal in which picture information is removed is coupled via a low-pass filter to an input terminal of a comparator having a predetermined threshold level. The comparator produces an output signal when a voltage at the input terminal is more positive than the threshold level, that is indicative of the occurrence of a vertical sync pulse. When any of equalizing and horizontal sync pulses occurs, the comparator output signal is not produced. A negative current source is coupled to the low-pass filter to provide level shifting of the comparator input voltage so as to increase a guard band or noise immunity of the sync separator.

Abstract: A sawtooth signal generator of a D.C. coupled vertical deflection circuit is responsive, during service mode of operation, to a first signal at a D.C. level that is indicative of vertical centering. During the service mode operation, the generation of the sawtooth signal is disabled and, instead, the generator generates a D.C. signal that is D.C. coupled via a vertical deflection amplifier to a vertical deflection winding in a manner to position an electron beam at the vertical center of a display screen.

Abstract: Retrace pulses are integrated by an R-C network to produce a ramp signal. The resistive member of the R-C network is bypassed by a diode to provide rapid retrace at the conclusion of the ramp portion of the integrated signal. A voltage divider at the output of the integrator adjusts the DC level of the ramp signal without affecting the constant of integration of the R-C network.

Abstract: In a vertical deflection circuit, a vertical deflection current is controlled by a vertical sawtooth signal. A transistor generates a first control signal that is derived by sensing the beam current. The control signal is used for modulating the vertical sawtooth signal to compensate for a tendency of the raster height on a screen of a cathode ray tube to increase when the ultor voltage decreases. The transistor also clamps a second control signal that is indicative of the beam current to a predetermined level when the beam current is smaller than a predetermined value. The second control signal is coupled to an automatic beam current limiter.
