  • Patent number: 11535064
    Abstract: An airless flexible tire including traction lug pairs each having a forward facing traction lug and a rearward facing traction lug cooperatively forming a divided Z or reverse divided Z shape. Each traction lug includes a lateral section and a central section. The central section extends from an end of the lateral section so as to straddle a centerline of the airless flexible tire and includes a number of discrete sidewalls. The discrete sidewalls are different sizes and angled relative to each other. The central sections of paired traction lugs form a space dividing portions of the Z or reverse Z shape. The central sections of nearest traction lugs of adjacent traction lug pairs form a space dividing the adjacent traction lug pairs.

  • Patent number: 11523001
    Abstract: An event driven monitoring device that can be configured to monitor a variety of operating conditions for a piece of equipment or system and may also report specific events related to these operating conditions to a central cloud-based server. The server can then broadcast customized alert information to other computers or systems configured to receive them. The monitoring device may accept input from many types of sensors allowing the device to detect and respond to changes in numerous types of sense parameters. Individuals and/or devices may receive reports from the remote server in response to certain events sent using any suitable protocol such as a text message, e-mail, push notification, or automated telephone call to name a few examples. The server may be configured with specialized rules programmed to determine which contacts should be notified for specific events related to individual pieces of equipment.

  • Publication number: 20220039336
    Abstract: A wheel track monitoring system for an irrigation system monitors the condition of a wheel track and alerts an operator and/or automatically takes corrective action when a wheel track develops ruts or other conditions that may adversely affect operation of the irrigation system. The wheel track monitoring system includes a wheel track condition sensor, a location sensor, and a processing system. The processing system receives and stores wheel track condition data and location data from the sensors as the irrigation system travels across a field and creates a log of wheel track condition data for multiple locations in the field. The processing system also analyzes the wheel track condition data to determine if the condition of the wheel track is unacceptable at any locations in the irrigated field and generates a corrective action signal if the condition is unacceptable.
