Abstract: A motor driver interface (MDI) circuit includes fault detection apparatus effective to detect short circuits to the power supply in the switching transistors of an H-bridge reversible DC motor arrangement.  A pair of timers distinguishes a true fault condition.  The first timer is responsive to a continuous fault detection to define a first time period from its initiation; and a second timer is responsive to a continuous presence of a transistor conduction signal to define a second time period from its initiation.  The apparatus stores a fault signal in response to the detection of the fault condition at the end of the first or second time periods with the first timer providing fault detection upon turn-on after the brief initial high transistor turn-on current and the second timer providing noise immunity.

Title: Method and apparatus for determining the flow rate of a viscous fluid stream
Inventor: ANGER STEVEN J
IPC: G01F1/7086
Filed: 1992-03-19
Abstract: A method of determining the flow rate of a viscous fluid stream comprises passing the fluid stream through a field of view of an electronic imaging device, which produces output signals representing images of the fluid stream at successive times t0, t1, ...tn. Signals representing an image of the fluid stream at a first time ti are stored in a first memory, while signals representing an image of the fluid stream at a second time tj, are stored in a second memory. The time tj - ti is less than the time taken for a point on the fluid stream to cross the field of view of the imaging device. The stored signals are then analyzed to derive width signals W(y) representing the width of the fluid stream as a function of y, where y represents a coordinate in the direction of fluid flow, and the first and second stored signals are compared to identify a common point on the fluid stream in the respective images represented thereby. A signal representing the flow rate of the fluid stream is derived from the width signals W(y) and signals representing at least the y coordinates y1, y2 of the common point in the respective images. This method permits the continual monitoring of the volumetric flow rate while taking into account fluctuations in the width of the stream. <IMAGE>
