Drivers are asked to step out of their vehicles and perform a few simple sobriety tests. One barefoot, tipsy woman keeps saying, “I’m sorry, I’m sorry,” as a Butler County Sheriff’s deputy escorts her to the breath-test machine. Her Toyota Solara is towed away.
By the time Fairfield police officers fold their checkpoint at 3 a.m., they have briefly stopped 688 vehicles and netted eight driving-under-the-influence arrests – including Richard Guinan, Hamilton County assistant prosecutor. Both Guinan and the woman of many apologies refused the breath test. Both were taken in for booking.
The June 15 checkpoint location, as usual, had been publicized in advance. Roadside floodlights and warning signs were set up shortly before 11 p.m.
Southbound traffic was funneled into a single lane. Patrol-car light bars flashed for hours.
Yet motorists still drove up high on alcohol or drugs, without driver’s licenses or not wearing seat belts. Two had outstanding warrants against them. Guinan earlier that day spent time at a prosecutor’s office golf outing and in the past had prosecuted drunken drivers.
Welcome to the world of tougher DUI enforcement.
But are sobriety checkpoints working here? Are they deterring drunken or drugged drivers?
An Enquirer analysis of 40 checkpoints for the four-county Southwest Ohio area since January 2006 found a total of 261 DUI arrests. That’s 261 out of more than 17,000 vehicles checked, or about one DUI arrest for every 67 vehicles.

microprocessor
A microprocessor is a programmable digital electronic component that incorporates the functions of a central processing unit (CPU) on a single semiconducting integrated circuit (IC). The microprocessor was born by reducing the word size of the CPU from 32 bits to 4 bits, so that the transistors of its logic circuits would fit onto a single part. One or more microprocessors typically serve as the CPU in a computer system, embedded system, or handheld device.
Microprocessors made possible the advent of the microcomputer in the mid-1970s. Before this period, electronic CPUs were typically made from bulky discrete switching devices (and later small-scale integrated circuits) containing the equivalent of only a few transistors. By integrating the processor onto one or a very few large-scale integrated circuit packages (containing the equivalent of thousands or millions of discrete transistors), the cost of processor power was greatly reduced. Since the advent of the IC in the mid-1970s, the microprocessor has become the most prevalent implementation of the CPU, nearly completely replacing all other forms. See History of computing hardware for pre-electronic and early electronic computers.
The evolution of microprocessors has been known to follow Moore's Law when it comes to steadily increasing performance over the years. This law suggests that the complexity of an integrated circuit, with respect to minimum component cost, doubles every 24 months. This dictum has generally proven true since the early 1970s. From their humble beginnings as the drivers for calculators, the continued increase in power has led to the dominance of microprocessors over every other form of computer; every system from the largest mainframes to the smallest handheld computers now uses a microprocessor at its core.

computer
A computer is a machine for manipulating data according to a list of instructions.
Computers take numerous physical forms. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers. Today, computers can be made small enough to fit into a wrist watch and be powered from a watch battery. Society has come to recognize personal computers and their portable equivalent, the laptop computer, as icons of the information age; they are what most people think of as "a computer". However, the most common form of computer in use today is by far the embedded computer. Embedded computers are small, simple devices that are often used to control other devices—for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and even children's toys.
A computer in a wristwatch.The ability to store and execute programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: Any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks as long as time and storage capacity are not considerations.
