Abstract: The disclosure provides systems and methods for data analysis of experimental data. The analysis can include reference data that are not directly generated from the present experiment, which reference data may be values of the experimental parameters that were either provided by a user, computed by the system with input from a user, or computed by the system without using any input from a user. Another example of such reference data may be information about the instrument, such as the calibration method of the instrument.

Abstract: An irrigation system for watering a group of large fields on which crops are grown. A water well is arranged on each field and an electric motor driven pump produces each water well. A motor/generator supplies current to an electric motor of each water well by a step-up transformer having a low voltage primary and a high voltage secondary winding to receive current from the electrical generator. The primary of a several step down transformers are connected in parallel to supply current to an irrigation pump motor. Each electric motor has a contact connected to current carrying electrical conductors that are buried below the surface of the ground. Well water is conveyed to a pivot type traveling irrigation system having a rotating coupling by which water is conveyed from said pump into the sprinkler system. All of the electrical conductors interconnecting the transformers and pump motors are placed underground.

Abstract: An ophthalmoscope for observing the fundus of an eye includes a casing, a light source for illuminating the fundus, lens means for viewing the illuminated fundus, electrical energy producing means for providing electrical energy to the light source and means electrically connecting the electrical energy producing means and the light source, the electrical energy producing means being supported on, extending substantially completely around and substantially conforming to the outer surface of the casing. Desirably, the electrical energy producing means is a battery having at least one battery section, each battery section including at least two substantially annular contact members and a plurality of battery cells arranged in spaced relation and disposed between and electrically connected to the contact members. The cells within each battery section are electrically connected in parallel and adjacent battery sections are electrically connected in series.
