Abstract: Systems and methods for use in identifying locations and/or sizes of trials in fields are provided. One example computer-implemented method includes defining a bounding box for a field based on a boundary line of the field and imposing multiple strips to the bounding box, where each strip has a dimension consistent with a desired planting pass for a trial in the field. The method also includes rotating the bounding box, with the strips, to an orientation consistent with a planting direction of the field and cropping the multiple strips consistent with one or more headlands of the field. The method then includes generating multiple candidate trials for the field, based on the multiple strips, calculating metrics for the candidate trials based on areas and shapes of the candidate trials, and selecting and publishing one or more of the candidate trials based on the metric as for implementation in the field.

Abstract: A method for automatic accompaniment generation to evoke specific emotion includes the steps of receiving a melody and a valence value, executing an accompaniment module, wherein the accompaniment module execution includes generating at least one harmonic progression composed of multiple chords corresponding to the valence value and matching the melody to form an accompaniment.

Abstract: A device capable of generating electricity includes a rotating unit and a piezoelectric component. The rotating unit is rotatable about a rotation axis and includes a plurality of strikers that are disposed at angularly spaced apart positions relative to the rotation axis and that define a plurality of voids, each of which is located between an adjacent pair of the strikers. The piezoelectric component has a portion that extends into one of the voids. Rotation of the rotating unit results in the strikers striking the portion of the piezoelectric component intermittently, and causes the piezoelectric component to deform, exhibit a direct piezoelectric effect and generate electricity.

Abstract: An electric coupler includes an insulating body having a coupling section at a front end thereof. The insulating body receives a plurality of terminals therein for coupling with a correspondingly constructed electric coupler. The electric coupler further includes two arcuate resilient members each including a first end integrally formed with an associated one of two opposite sides of the insulating body and a second end integrally formed with the associated one of the opposite sides of the insulating body, with a remaining portion of each arcuate resilient members being spaced from the associated one of the opposite sides of the insulating body. The remaining portion of each arcuate resilient member includes a retaining protrusion formed on a section thereof adjacent to the second end of the arcuate resilient member, with the retaining protrusion being engaged with and thus positioned by the correspondingly constructed electric coupler.
