Abstract: Utilizes machine vision to thin fields, for example by selectively spraying plants with enough fertilizer to kill the plants, for example to maintain a minimum distance between plants or to enable remaining plants to grow in a pattern, for example two dimension diamond pattern. The use of fertilizer to kill plants has the benefit of fertilizing the field, i.e., the remaining plants not to be killed, at the same time. This unexpected result which occurs in the thinning and simultaneous fertilizing of a field is based the discovery that immature plants are more sensitive to fertilizer than mature plants. The system and method eliminates the need for harmful chemicals and mechanical thinners and may be retrofitted onto existing spray systems and platforms, thus eliminating herbicides and thinning machinery.

Abstract: A sensor that detects contact using compression of a compliant material sandwiched between an electromagnetic signal transmitter and a corresponding signal receiver. Potential applications include inexpensive, robust collision sensors integrated into mobile robot bumpers, and sensors on robot grippers to detect grasping of an object. Deformation of the compliant material in response to contact forces changes the distance between the transmitter and the receiver, affecting the electromagnetic field between them. Changes in this electromagnetic field provide information on the location and magnitude of the contact forces. A transmitter and receiver may form opposing surfaces of a capacitor; the measured capacitance changes as the distance between transmitter and receiver changes. Alternatively, the strength of a received signal may be monitored to detect changing distance between transmitter and receiver. Shielding and signal filtering may be used to mitigate the effects of electromagnetic noise.
