The precision of proprioceptive position sense

Experimental Brain Research, 1998
The purpose of this study was to determine the precision of proprioceptive localization of the hand in humans. We derived spatial probability distributions which describe the precision of localization on the basis of three different sources of information: proprioceptive information about the left hand, proprioceptive information about the right hand ...

Soil macronutrient sensing for precision agriculture

Journal of Environmental Monitoring, 2009
Accurate measurements of soil macronutrients (i.e., nitrogen, phosphorus, and potassium) are needed for efficient agricultural production, including site-specific crop management (SSCM), where fertilizer nutrient application rates are adjusted spatially based on local requirements.

Applications of Sensing to Precision Irrigation

2021
Precision irrigation aims at improving productivity and sustainability by addressing spatial as well as temporal variability of soil and crop water status. This chapter presents three case studies from south-eastern USA, Israel and Spain which relate to different attributes of precision irrigation: (1) type of precision: whether it targets the spatial ...

Remote sensing for precision weed management

Pest Management Science
AbstractHerbicides are important for controlling and avoiding the impact of weeds in reducing crop productivity. Traditionally, herbicides are applied uniformly over crop fields. With the advancement of precision agriculture, it is now possible to apply herbicides site‐specifically with precision operations over the crop fields.

A precision high-voltage current sensing circuit

IEEE Transactions on Circuits and Systems I: Regular Papers, 2008
This paper presents a precision current sensor featuring a high voltage, high gain (~ 140 dB), and low input offset ( < 1 mV) current sense amplifier. This amplifier does not require offset trimming even for low offset applications. It is a single stage amplifier that has a common gate pMOS differential input pair, which makes it inherently stable ...

Fuzzy logic and position sensing for precision assembly

Journal of Robotic Systems, 1995
AbstractThe problem of part mating and assembly with close tolerances has been addressed in the past by active or passive compliance and by force/position control. With ambient sensor and transmission noise and with imprecise measurements it is often difficult to attain high precision in manipulator positioning.

Sensing Water Properties at Precise Depths from the Air

Journal of Field Robotics, 2017
AbstractWater properties are critical to our understanding and managing of freshwater systems that change rapidly with depth. This work presents an unmanned aerial vehicle (UAV) ‐based method of keeping a submerged, cable‐suspended sensor payload at a precise depth, with 95% of sensor readings within ±8.4 cm of the target depth.
