The present invention is a nodal radar system having a metamaterial-based object detection system. An intelligent antenna metamaterial interface (IAM) associates specific metamaterial unit cells into sub-arrays to adjust the beam width of a transmitted signal. The nodal radar system is positioned on infrastructure to complement sensor information from mobile vehicles and devices within an environment.

Nodal metamaterial antenna system

Embodiments are directed to an apparatus that includes a fluidic structure and optical components. The fluidic structure includes a transparent channel through which objects in an analyte fluid can travel along respective paths during operation of the apparatus. The optical components are configured to provide measurement light to the objects traveling through the transparent channel. The fluidic structure is configured to reversibly engage with a host structure. The host structure includes a source of the measurement light and electronics to receive and process output light emanating from the objects traveling in the channel. The fluidic structure makes an air-tight seal when engaged with the host structure.

Embodiments of an apparatus and methods can removing unwanted plants or weeds from an area such as an agricultural plot or lawn. The apparatus includes a three-dimensional imager configured to capture plant images and locate plants; an image processor configured to distinguish between wanted and unwanted plants based upon the captured plant images; at least one laser device configured to emit a laser beam having power sufficient to damage the unwanted plants; a guidance system configured to direct at least one laser beam toward the unwanted plant; and a chassis configured to support the three-dimensional imager, the laser device, and the guidance system. The chassis is configured to be moved across the area.

Unwanted plant removal system having variable optics

An apparatus and methods are provided for removing unwanted plants or weeds from an area such as an agricultural plot or lawn. The apparatus includes a three-dimensional imager configured to capture plant images and locate plants; an image processor configured to distinguish between wanted and unwanted plants based upon the captured plant images; at least one removal device configured to damage a target on the unwanted plants; a guidance system configured to direct at least one laser beam toward the unwanted plant; a stabilization system configured to provide feedback compensation to one or both of the three-dimensional imager and the guidance system; and a chassis configured to support the three-dimensional imager, the laser device, the guidance system, and the stabilization system. The chassis is configured to be moved across the area.

Unwanted plant removal system having a stabilization system

Embodiments include an apparatus and methods for removing unwanted plants or weeds from an area such as an agricultural plot or lawn. The apparatus includes a three-dimensional imager configured to capture plant images and locate plants; an image processor configured to distinguish between wanted and unwanted plants based upon the captured plant images; at least one laser device configured to emit a laser beam having power sufficient to damage the unwanted plants; a laser beam controller configured to direct at least one laser beam toward the unwanted plant; and a chassis configured to support the three-dimensional imager, the laser device, and the laser beam controller. The chassis is configured to be moved across the area.

Unwanted plant removal system

Embodiments are directed to a host structure that includes a waveguide configured to deliver measurement light to a compartment at least partially within the host structure. The compartment is configured to reversibly engage a fluidic optical cartridge. The host structure also includes a detector configured to receive and process output light emanating from the fluidic optical cartridge as well as electronics to process signals from the detector.
