Toledo counter-top fan scale Toledo dial scale A Toledo scale used in a hospital cafeteria Allen DeVilbiss, Jr. (1873-1911) was an inventor who lived in Toledo, Ohio , United States. He became interested in the concept of weighing machines, and conceived the idea of an automatic computing pendulum scale.
An instrument driver, in the context of test and measurement (T&M) application development, is a set of software routines that simplifies remote instrument control. Instrument drivers are specified by the IVI Foundation [1] and define an I/O abstraction layer using the virtual instrument software architecture (VISA). The VISA hardware ...

Scala is a freeware software application with versions supporting Windows, macOS, and Linux.It allows users to create and archive musical scales, analyze and transform them with built-in theoretical tools, play them with an on-screen keyboard or from an external MIDI keyboard, and export them to hardware and software synthesizers.
Before using a triple beam balance, the scale pointer should be at zero. [6] The zero adjustment knob can be used to adjust the scale pointer. Place the objects on the pan and adjust the riders until the scale pointer is at zero again, and then sum the weights marked (e.g. the 4th notch of 100 gram beam is 400g) to find the weight of the sample.

Test drivers and test stubs are both instrumental in software testing, but they serve distinct roles within a test harness. Test drivers are typically an active component and control or call the system under test without further inputs after they are initialised, stubs on the other hand are usually passive components that only receive data and ...
