Abstract: A voltage regulation circuit includes an active integrator circuit which generates an output signal representing the time integral of the error between the voltage across a load and a reference voltage. The integrator circuit output is connected to a series of voltage comparators (each having hysteresis) each of which controls one of a series of separate switch elements each controlling a proportion of the total current flow from a source to the load.

Abstract: An electronic fuel injection system includes a mass flow transducer, an integrator which periodically accumulates a signal corresponding to the total mass of air aspirated into the engine during a preceding fraction of an engine cycle, a signal storage capacitor which is charged periodically to the integrator output voltage under the control of an analog gate, a controlled current source normally giving a constant current, but overridingly controllable by the integrator output at extremes of the range of the integrator output and connected to discharge the capacitor and a comparator sensing the voltage on the capacitor and controlling the length of time for which the injector is open.

Abstract: A dispense edge member for detaching a pressure-sensitive label from a backing strip is shaped to impart a transverse curvature to the label during detachment from the backing strip. The curvature increases the rigidity of the label and prevents drooping of the label.
