A mesh-based wireless networkof sensor/actuator devices I, D, T for an agricultural production area involves battery-powered sensors and actuators deployed under or within the foliage for broadcast communication with at least one repeater R according to broadcast time slots. The repeaters R are mounted above the vegetation canopy so as to be powered by solar panels. The repeaters R form a mesh network for routing data and commands to and from the sensors and actuators and at least one gateway GW. The gateway communicates over a cellular network with a remote agricultural management serverand database

Monitoring and control systems for the agricultural industry

Apparatus for optically measuring a remote object comprises at least one source for projecting a plurality of discrete zones of electromagnetic radiation (for example laser spots) along a projection plane. Imaging apparatus images a plurality of reflections from the remote object. By spatially offsetting the imaging apparatus from the projection plane, crosstalk between opposing cameras imaging the same object is more easily avoided. The same effect as spatially offsetting the imager can be achieved by rotating the light source to provide a reflection axis that is not perpendicular to the optical axis.

Multiple axis multipoint non-contact measurement system

A teat location system for automated milking systems comprises a light projection source and a camera having a two dimensional array of pixels, each of which is capable of returning time of flight information as well as intensity. Depth of field limitations and the problem of overlapping teat images are thereby overcome or minimized.

Time of flight teat location system

Apparatus for optically measuring a remote object comprises at least one source for projecting a plurality of discrete zones of electromagnetic radiation (for example laser spots) along a projection plane. Imaging apparatus images a plurality of reflections from the remote object. By spatially offsetting the imaging apparatus from the projection plane, easier discrimination and identification of the reflections is made possible.

Disclosed herein are TV Camera based electro-optical sensors, providing affordable methods and apparatus for high speed determination of dimensions and other features of objects. Preferred embodiments utilize addressable line or pixel based cameras to effect triangulation based and other machine vision sensing of objects.

High speed camera based sensors

Disclosed herein are TV Camera based and other electro-optical sensors and systems, providing affordable methods and apparatus for high speed determination of dimensions and other features of objects. Particular embodiments capable of fast and reliable acquisition of features of moving objects such as boards and wood products are disclosed. Preferred embodiments utilize laser triangulation range detection with at least two cameras viewing the same laser spot or line projected on the object.
