The History of Clocks | |The history of clocks is very long‚ and there have been many different types of clocks over the centuries. Not all historians agree on the history of the clock. The word clock was first used in the 14th century (about 700 years ago). It comes from the word for bell in Latin ("clocca"). Using the Sun The first way that people could tell the time was by looking at the sun as it crossed the sky. When the sun was directly overhead in the sky‚ it was the middle of the day‚ or

Monitor Alarm Fatigue Courtney Conner University of South Alabama Strategies to Reduce Monitor Alarm Fatigue Monitor alarms are designed to alert caregivers to changes in a patient’s condition and can save lives‚ but majority of the alarms do not require clinical intervention. However‚ as the number of alarms encountered by clinicians on a daily basis rises‚ it has become difficult for caregivers to distinguish between clinically significant alarms and nuisance alarms. As a result‚ alarm fatigue

PROPELLER CLOCK OBJECTIVE :- In this project‚ our aim is to use PIC or 8051 microcontroller to control a row of LEDs to function it as a clock. ABSTRACT :- The Propeller Clock is an electronic device which has a series of LEDs on board that rotate with the help of a motor to give an illusion of a watching a clock ( Digital or Analogue ). This requires a DC motor which rotates the PCB connected to it with sufficient speed so as to create the illusion. The LEDs are connected to a microcontroller

"Propeller Clock" Mechanically Scanned LED Clock Seven light emitting diodes spin‚ giving the illusion of numbers in the air An Overview: Top View Side View How this clock works: A motor spins the "propeller"‚ and a small microprocessor keeps track of time and changes the pattern on seven LEDs with exact timing to simulate a 7 by 30 array of LEDs. It is an illusion‚ but it works nicely. To build this clock‚ few things are needed‚ including: 1. Skill with motors and mechanical

The Life Cycle and the Social Clock Early models of adult development sometimes assumed that marriage is a requisite life task for full adulthood. Stage models posited a linear set of stages that people progressed through over the course of a lifetime. The concept of the social clock describes societal expectations for the time at which people are expected to marry‚ have children‚ and accomplish other life tasks. What are the implications of these expectations for the ways in which people who are

Running Head: FIRE SPRINKLER ALARM Fire Sprinkler Alarm Christopher Sazon Justine Vergara Legazpi City High School CHAPTER I Introduction Fire is extraordinary helpful. It gave humans the first form of portable light and heat. It also gives us the ability to cook food‚ forge metal tools‚ form pottery‚ harden bricks and drive power plants. But at the same time‚ fire can destroy houses and possessions in less than hour. It can also reduce an entire forest to a pile of

Fire alarm circuit ABSTRACT Here is a simple fire alarm circuit based on a Light Dependent Resistor (LDR) and lamp pair for sensing the fire. The alarm works by sensing the smoke produced during fire. The circuit produces an audible alarm when the fire breaks out with smoke. When there is no smoke the light from the bulb will be directly falling on the LDR. The LDR resistance will be low and so the voltage across it (below 0.6V). The transistor will be OFF and nothing happens. When there is sufficient
