Frequency-frequency graphical user interface for independent frequency control of the shaker head of a harvester

A method for controlling a shaker having a first shaking frequency and a second shaking frequency using a user interface on a touchscreen of a computing device, the method comprising:

• (i) providing, by the user interface on the touchscreen, a display region having a plurality of locations, each location in the display region corresponding to:
• a. a first frequency of a first frequency axis, the first frequency representing a first shaking frequency of a first mass of the shaker, and
• b. a second frequency of a second frequency axis, the second frequency representing a second shaking frequency of a second mass of the shaker;
• (ii) detecting, by the user interface, a contact with the touchscreen at a point of contact;
• (iii) while detecting the contact:
• a. detecting, by the user interface, the point of contact at one or more locations among the plurality of locations within the display region;
• and
• b. for a subset of the one or more contacted locations, associating, by the user interface, a time of contact with each contacted location;
• and
• (iv) saving, by the user interface, the shake by storing the subset of the one or more contacted locations with the associated times.

A non-printed, computer-readable media comprising instructions, which when executed by a processor of a computing device with an associated touchscreen, perform the steps of a method for controlling a shaker having a first shaking frequency and a second shaking frequency using a user interface on a touchscreen of a computing device, the method comprising:

• (i) providing, by the user interface on the touchscreen, a display region having a plurality of locations, each location in the display region corresponding to:
• a. a first frequency of a first frequency axis, the first frequency representing a first shaking frequency of a first mass of the shaker, and
• b. a second frequency of a second frequency axis, the second frequency representing a second shaking frequency of a second mass of the shaker;
• (ii) detecting, by the user interface, a contact with the touchscreen at a point of contact;
• (iii) while detecting, by the user interface, the contact:
• a. initiating, by the user interface in response to the contact, a shake of the shaker;
• b. detecting, by the user interface, the point of contact at one or more locations among the plurality of locations within the display region;
• c. in response to detecting the point of contact at a location:
• i. setting, by the user interface, the first shaking frequency of the first mass according to the first frequency corresponding to the contacted location;
• and
• ii. setting, by the user interface, the second shaking frequency of the second mass according to the second frequency corresponding to the contacted location;
• and
• (iv) detecting, by the user interface, no contact with the touchscreen;
• (v) in response to detecting no contact, ending, by the user interface, the shake.
