Systems and methods are provided for updating an agricultural prescription for a geographic region. An example computer-implemented method includes executing an agricultural prescription, via farming equipment, in a geographic region and receiving, during execution of the prescription, sensor data from the farming equipment and operating data representing local operating settings for the farming equipment. Task execution data for the agricultural prescription is generated based on the received sensor data and received operating data for the farming equipment, and compared to expected data for execution of the prescription by the farming equipment. Then, in response to the comparison exceeding a threshold, a corrective action for the farming equipment is initiated wherein an alert is generated and, in response, an updated agricultural prescription is executed, via the farming equipment, by overriding the local operating settings for the farming equipment with corrective operating settings included in the updated prescription.

Updating execution of tasks of an agricultural prescription

A method begins by agriculture equipment collecting current on-site gathered agriculture data regarding an agriculture region and sending at least a representation of the current on-site gathered agriculture data to a host device. The method continues with the host device processing one or more of the at least a representation of the current on-site gathered agriculture data, current off-site gathered agriculture data, historical on-site gathered agriculture data, historical off-site gathered agriculture data, and historical analysis of agriculture predictions regarding the agriculture region to produce a current agriculture prediction for the agriculture region. The method continues with the host device generating an agriculture prescription regarding at least a portion of the agriculture region based on the current agriculture prediction and sending the agriculture prescription to one or more of the agriculture equipment.

Generating an agriculture prescription

A method begins by a computing device allocating a plurality of tasks of an agricultural prescription for a farming geographic area to a fleet of farming equipment. While executing tasks of the plurality of tasks, the method continues with at least some of the fleet of farming equipment collecting task execution data. Based on the task execution data, the method continues with the computing device updating at least one of the agricultural prescription, the plurality of tasks, and the allocation of at least one task of the plurality of tasks.

A method begins by a drive unit affiliated with farm equipment receiving data from the farm equipment to produce agricultural data. The method continues with the drive unit determining a filtering constraint based on one or more parameters selected from a plurality of lists of agricultural parameters and filtering the agricultural data based on the filtering constraint to produce filtered agricultural data. The method continues with the drive unit determining processing of the filtered agricultural data and executing the processing of the filtered agricultural data.

Collecting data to generate an agricultural prescription

A mechanism for determining an error vector magnitude EVMfor a signal transmitted by a device under test (DUT). A receiver (typically an RF signal analyzer) produces a baseband signal in response to the signal transmission. An OFDM input signal (derived from the baseband signal) is accessed from memory. The OFDM input signal includes a sequence of time-domain OFDM input symbols. A reference signal is accessed from the memory. The reference signal includes a sequence of time-domain OFDM reference symbols. EVMis computed in the time domain based on a time-domain difference signal, i.e., a time-domain difference between the sequence of time-domain OFDM input symbols and the sequence of time-domain OFDM reference symbols. The error vector magnitude EVMis determined without transforming the sequence of time-domain OFDM input symbols to the frequency domain. The error vector magnitude EVMis related to a standard-defined composite EVM by a scalar multiple.

Time-domain mechanism for computing error vector magnitude of OFDM signals

Method and system for a test process. The method may include performing tests on one or more units under test (UUTs). At least one test on one or more UUTs may be performed. A signal may be acquired from the UUT. A reference signal may be retrieved. The reference signal may be derived from a transmitted signal characteristic of the UUT. The signal may be analyzed with respect to the reference signal. Results, useable to characterize the one or more UUTs, from performing the at least one test on the one or more UUTs may be stored. The reference signal may be derived from an initial test and may be stored for subsequent retrieval. A respective reference signal may be retrieved for all UUTs of the one or more UUTs for a respective test. The signal may be a radio frequency signal. The UUT may be a wireless mobile device.

Unit testing and analysis of multiple UUTs

Device and method for outputting a leaked radio frequency (RF) signal useable for triggering devices under test (DUTs). The device may include a vector signal analyzer (VSA) which may also perform the method for triggering DUTs. The VSA may include a first component, configured to generate an RF signal, an input configured to receive RF signals transmitted from DUTs, and a received RF signal conditioning portion, each coupled to an internal switching portion. The VSA may be configured to generate the RF signal via the first component, leak the RF signal from the first component to the internal switching portion, generating a leaked RF signal, route the leaked RF signal to the input, bypassing the received RF signal conditioning portion and output the leaked RF signal which is useable to trigger DUTs via the input.

A robotic mower boundary sensing system includes a boundary driving circuit on a charging station transmitting an encoded signal on a boundary wire, a boundary sensor on a robotic mower and including an inductor receiving the encoded signal, and a vehicle control unit on the robotic mower receiving the encoded signal from the boundary sensor and decoding the signal and cross correlating the received signal to determine the distance of the boundary sensor from the boundary wire.

A system and method for estimating a time delay introduced by an envelope tracking amplifier (ETA) of a transmitter. The ETA receives a first baseband signal that is generated by the transmitter and operates on the first baseband signal to produce an output signal. The receiver receives a second baseband signal in response to the transmitter's transmission of the output signal. The receiver generates a model signal that represents an estimate of the first baseband signal. The receiver computes a first time delay between the amplitude envelopes of the second baseband signal and the model signal. The receiver computes a second time delay between phase signals derived respectively from the second baseband signal and the model signal. The receiver estimates the time delay that is introduced by the ETA of the transmitter by subtracting the second time delay from the first time delay.
