摘要:
A method, apparatus and computer-usable medium for improved load testing of subsystems comprising a larger system by intelligently and stochastically distracting virtual users from healthy subsystems such that they collaboratively converge on a subsystem exhibiting operating health problems. Virtual users are progressively targeted at a degraded subsystem to force it to sustain its respective share of a test workload, thereby exacerbating its behavior to facilitate problem determination and resolution. Virtual users that have failed or terminated in an unhealthy subsystem are replaced by selectively and intelligently redistributing virtual users from healthy systems. As virtual users are redistributed to the degraded subsystem and fail or terminate, additional performance and behavior data is generated as the subsystem degrades to an unusable or non-operational state. By accelerating time-to-failure, test cycle intervals are reduced and the number of identified performance defects are maximized.
摘要:
A brake light enhancer circuit which may be inserted into a conventional motor vehicle lighting system to provide a more eye catching braking or deceleration signal to following drivers. The circuit may be connected between the rear signal lamps, brake light switch and flasher in a conventional vehicle lilghting system. It may include a timer or pulse generator, a counter and a disable latch. In motor vehicles having a pair of left and right turn signal lamps and a pair of left and right brake lamps, closure of the brake light switch when the turn signal switch is in its neutral position will cause the brake lamps to flash on and off a predetermined number of times and to thereafter remain continuously illuminated. When the turn signal switch is moved to either its left or right turn position, the brake light enhancer circuit is disabled so that turn and brake light signals are conventional, thereby preventing confusion of following drivers.
