Abstract: A VCO modulator controller including a ROM memory storing a number of waveform maps, a counter coupled to the ROM memory and capable of developing a sequence of ROM addresses, a temporal bit generator responsive to a data stream to develop a next bit Nb, a current bit Cb, and a past bit Pb, control circuitry developing a digital waveform signal from selected waveform maps in the ROM memory using the Nb, Cb, and Pb bits and the sequence of ROM memory outputs, and a DAC that converts the digital waveform signal to an analog VCO control signal that encodes said data stream.

Abstract: Macrocells, e.g., Random Access Memory (“RAM”), are arranged in columns and disposed in a core of an integrated circuit (IC) chip. The macrocells can abut each other within the columns or can be separated from each other by standard cells which are disposed to fill gaps between the macrocells within the columns. Power/ground rails are disposed vertically along the sides of the columns. The power/ground rails run the full height of the core and couple to a power/ground ring disposed along the perimeter of the core. The power/ground rails also couple to the macrocells and the standard cells and provide power to those cells. The columns can form right angles with horizontal standard cell rows, thus enabling the standard cells to couple easily to the vertically disposed power/ground rails.

Abstract: Multiplexers are used to generate synchronized slave clocks from a common master clock. A first multiplexer and a second multiplexer generate a first slave clock and a second slave clock, respectively, from the common master clock. A third multiplexer and a fourth multiplexer are configured as a divide-by-n circuit for providing a third slave clock that is a divided version of the second slave clock. A fifth multiplexer provides a matching delay to preserve the synchronization between the first slave clock and the other slave clocks. A sixth multiplexer is used to select between the second slave clock and the third slave clock in response to a select signal. A flip-flop may be used to provide the select signal and to guard against false selection of slave clocks.

Abstract: A seed monitor includes a planter master unit having one or more planter counting units connected to the planter master unit, with each planter counting unit associated with a different seed tube. Each planter counting unit includes a light source, a means for forming a light beam that traverses a sensing area of a seed tube, a detector and a processor. The circuit board connects the detector and light source with a processor. The processor adjusts the intensity of the light source and selects an output amplifier gain that is appropriate for the counting of seeds. In this manner, the planter monitoring system adjusts for long-term dust and dirt accumulation and aging of components. The processor processes the selected stage of amplified output from the detector and determines the number of seeds that have traversed the sensing area of the associated seed tube. The planter master unit receives binary data of the counted seed, and from this data, provides an output to the operator.

Abstract: An apparatus and method for removably attaching one or more optical fibers so as to be in alignment with a respective electro-optic component on a circuit board within an enclosure. In a first embodiment, the header attaches to an aperture of an enclosure, thereby protecting the circuit board from dust and liquids. In a second embodiment, the header and protective enclosure are one integral unit. The invention enables one or more optical fibers to be detachably attached to a first side of a header or header/enclosure, and for a circuit board having one or more electro-optic components precisely positioned thereon to be attached to the other side thereof and accessed by the attached fiber by a through-hole in the header. A ferrule surrounds at least one optical fiber near an end thereof and includes a seating surface which seats on the exterior side of the header or header/enclosure.

Abstract: A seed blockage monitoring system employs a flexible, generally flat piezoelectric seed sensor element inserted at an acute angle of about 13 degrees into a seed flow path so that a portion of seeds traveling in the seed flow path strike the seed sensor element, preventing damage to the seeds and maintaining forward momentum of all seeds in the seed flow path. In order to provide flexibility in monitoring seeds of different types and to increase the data rate that information can be obtained from numerous multiple seed sensor elements, the use of a one-shot to temporarily store a seed detection signal and serial sampling of the temporarily stored signals from the sensors as in the prior art is avoided. Instead, a comparator that includes a diode in a feedback loop so as to function as a latch is used in conjunction with a serial shift register that has parallel data input lines.

Abstract: A method and circuit for determining whether a sensor 2 is attached to a connection point 5 of a sensor interface circuit 1 of a seed monitoring system. When it is desired to determine whether a sensor is attached to a connection point, the method applies a time varying detection signal at terminal 3 to the connection point 5 via a reactive element, such as capacitor 4. The connection point 5 is connected to a first input of a comparator 9 having its other input set at a first reference voltage which maintains the comparator in a first state in the absence of a detection signal being applied. Even when a detection signal is applied, the comparator is not driven into a second state if an operable sensor is connected to the connection point 5. When the sensor is not connected to the connection point, or is inoperable, the voltage produced by the detection signal at the first input of the comparator is high enough to trip the comparator into a second state, which may be latched.

Abstract: A particle blockage monitoring system employs a flexible piezoelectric particle sensor element in a portion of a particle flow path so that a number of particles traveling in the particle flow path strike the flexible particle sensor element while preventing damage to the particles and maintaining the forward momentum of all the particles in the particle flow path. In order to provide flexibility in monitoring particles of different types and to increase the information rate, the use of a one-shot multivibrator to temporarily store a particle detection signal as in the prior art is avoided. Also, serial sampling of the particle sensor data is avoided to increase the information rate. Instead, a comparator that includes a diode in a feedback loop so as to function as a latch is used in conjunction with a serial shift register that has parallel data input lines.
