Stopwatch

A stopwatch is a handheld timepiece designed to measure the amount of time elapsed from a particular time when it is activated to the time when the piece is deactivated. A large digital version of a stopwatch designed for viewing at a distance, as in a sports stadium, is called a stopclock.

The timing functions are traditionally controlled by two buttons on the case. Pressing the top button starts the timer running, and pressing the button a second time stops it, leaving the elapsed time displayed. A press of the second button then resets the stopwatch to zero. The second button is also used to record split times or lap times. When the split time button is pressed while the watch is running, the display freezes, allowing the elapsed time to that point to be read, but the watch mechanism continues running to record total elapsed time. Pressing the split button a second time allows the watch to resume display of total time.

Mechanical stopwatches are powered by a mainspring, which must be periodically wound up by turning the knurled knob at the top of the watch.

StopWatch (Campaign)

StopWatch is a joint venture between a range of civil society organisations, activist and human rights groups, academics and campaigners. StopWatch was established to address concerns about the use of Stop and Search powers by police in the UK with regards to law, community relations and civil rights. Its primary target is addressing the significant ethnic dis-proportionality in the use of stop and search; however, it also aims to review the use of powers which do not require reasonable suspicion to order a stop and search such as section 60 and to ensure effective monitoring and accountability are employed in conjunction with Stop and Search powers. It also aims to promote more effective methods of policing that do not have the same impact upon civil liberties and community relations.

The StopWatch Campaign involves: Equanomics UK; Federation of Student Islamic Societies (FOSIS); Mannheim Centre for Criminology, LSE; Muslim Safety Forum; NACRO; Not Another Drop;Open Society Justice Initiative; Release;The Runnymede Trust; School of Law, King’s College London; Second Wave; and Turning Point.
