The disclosure relates to agricultural systems. The systems have stalk sensor assemblies and/or data visualization systems. The stalk sensor assemblies are configured for assessing the size and other characteristics about crops, such as corn and other grains entering an agricultural implement, such as a harvester. The stalk sensor assemblies may use an estimation of the stalk perimeter to establish stalk size and therefore further features about the crop. The visualization system utilizes data from the stalk sensor assemblies to calculate and display relevant information about the crop.

A device for measuring a dimension includes: an electronic tape measure including: a portable casing including an opening having a Y axis; a winder in the casing having an X axis; a tape passing through the casing opening and including an end fixed on the winder and a free end outside the casing; a module for measuring a measurement relating to said outer section; a trigger for generating a signal by the trigger activation; and an interpretation module for controlling inputting of the measurement when the trigger signal is received, in which device the free end of the outer section includes a fastener, and the casing includes a fastening region allowing the fastener to be fixed, the length of the surface of the casing that extends between the fastening region and the opening of the casing being less than 4 cm.

Aspects of the subject disclosure may include, for example, obtaining a first plurality of circumference measurements, each of the first plurality of circumference measurements corresponding to a first circumference around a limb of a person at a respective one of a plurality of locations of the limb, each of the first plurality of circumference measurements being obtained from a respective one of a plurality of elastic measurement elements that is positioned at a respective one of the locations; determining, based upon the first plurality of circumference measurements, a first geometric profile along a length of the limb; and outputting data representing the first geometric profile. Other embodiments are disclosed.

The present invention provides an apparatus for measurement of a limb circumference, comprising a pull string module, a first measurement module and a second measurement module. The pull string module comprises a surrounding component, wherein the surrounding component comprises an encircling part disposed around a limb of an individual; the first measurement module is disposed at the pull string module and moves alone the longitudinal axis of the limb and meanwhile measures the length of the limb; and the second measurement module measures the length of the encircling part simultaneously when the first measurement module move alone the limb, so as to determine the correlation between the limb length and the limb circumference. The present invention further provides a device including two or more apparatuses of the present invention to measure the limb compliance and to be used in the treatment of lymphedema.

A measuring tape for measuring the size of limbs or waists is provided with a tape head capable of being stably inserted into a positioning hole during measurement and being automatically ejected out of the positioning hole after measurement, and includes a shell, and a cavity formed in the shell and used for receiving a flexible rule. An elastic switch assembly for clamping the tape head in the positioning hole is disposed at a position, close to the positioning hole, in the cavity. The elastic switch assembly and a leaf spring are disposed in the positioning hole, allowing the tape head to be inserted thereinto, in the shell, such that the tape head can be stably disposed in the positioning hole after being inserted into the positioning hole, and will not slide out of the positioning hole when users observe measure data.

Generally, a device to measure the circumference of circular objects. Specifically, a device including a pair of slidingly engaged members disposed between a pair of arms configured to be engaged with tread on a tire at about the midline of a wheel, an electrical circuit which varies in output voltage based on the distance between the pair of arms, and a processor communicatively coupled to a non-transitory computer readable medium containing a program which correlates the output voltage of the electrical circuit to a unit measure of distance between the pair of arms and calculates tire circumference.
