Traffic Officer
Traffic police (also known as traffic officers, traffic enforcement units, traffic cops, traffic monitors, or traffic enforcers) are units and agencies who enforce traffic laws and manage traffic. Traffic police help to assist in patrolling highways, directing traffic and address traffic infractions. They may be a separate agency from a main police agency, a unit or division within a police agency, or a type of assignment issued to officers; they can also be part of a transportation authority or highway authority. It has been noted that: History Traffic police have existed in some form for nearly three centuries. Possibly the first traffic police force was established in London, England in 1722, when the Lord Mayor of London, in response to an increase in traffic during the 18th century, appointed three men to position themselves on London Bridge and ensure traffic kept to the left side of the road and did not stop in traffic, with the aim of ensuring traffic could co ...

London Bridge
The name "London Bridge" refers to several historic crossings that have spanned the River Thames between the City of London and Southwark in central London since Roman Britain, Roman times. The current crossing, which opened to traffic in 1973, is a box girder bridge built from concrete and steel. It replaced a 19th-century stone-arched bridge, which in turn superseded a 600-year-old stone-built medieval structure. In addition to the roadway, for much of its history, the broad medieval bridge supported an extensive built up area of homes and businesses, part of the City's Bridge (City of London ward), Bridge ward, and its southern end in Southwark was guarded by a large stone City gateway. The medieval bridge was preceded by a succession of timber bridges, the first of which was built by the Roman Empire, Roman founders of London (Londinium) around AD 50. The current bridge stands at the western end of the Pool of London and is positioned upstream from previous alignments. Th ...

Glove
A glove is a garment covering the hand, with separate sheaths or openings for each finger including the thumb. Gloves protect and comfort hands against cold or heat, damage by friction, abrasion or chemicals, and disease; or in turn to provide a guard for what a bare hand should not touch. Gloves are made of materials including cloth, knitted or felted wool, leather, rubber, latex, neoprene, silk, and (in mail) metal. Gloves of kevlar protect the wearer from cuts. Gloves and gauntlets are integral components of pressure suits and spacesuits. Latex, nitrile rubber or vinyl disposable gloves are often worn by health care professionals as hygiene and contamination protection measures. Police officers often wear them to work in crime scenes to prevent destroying evidence in the scene. Many criminals wear gloves to avoid leaving fingerprints, which makes the crime investigation more difficult. However, the gloves themselves can leave prints that are just as unique as human fingerp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helmet
A helmet is a form of protective gear worn to protect the head. More specifically, a helmet complements the skull in protecting the human brain. Ceremonial or symbolic helmets (e.g., a policeman's helmet in the United Kingdom) without protective function are sometimes worn. Soldiers wear combat helmets, often made from Kevlar or other lightweight synthetic fibers. The word ''helmet'' is derived from ''helm'', an Old English word for a protective head covering. Helmets are used for most sports (e.g., jockeys, American football, ice hockey, cricket, baseball, skiing, hurling and rock climbing); dangerous work activities such as construction, mining, riot police, military aviation, and in transportation (e.g. motorcycle helmets and bicycle helmets). Since the 1990s, most helmets are made from resin or plastic, which may be reinforced with fibers such as aramids. Designs Some British gamekeepers during the 18th and 19th centuries wore helmets made of straw bound together wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

High-visibility Clothing
High-visibility clothing, sometimes shortened to hi vis or hi viz, is any clothing worn that is highly luminescent in its natural matt property or a color that is easily discernible from any background. It is most commonly worn on the torso and arm area of the body. Health and safety regulations often require the use of high visibility clothing as it is a form of personal protective equipment. Many colors of high visibility vests are available, with yellow and orange being the most common examples. Colors other than yellow or orange may not provide adequate luminescence for conformity to standards such as ISO 20471. As a form of personal protective equipment, high-visibility clothing is worn to increase a person's visibility and therefore prevent accidents caused by persons not being seen. As a result, it is often worn in occupations where hazardous situations are created by moving vehicles or low lighting conditions. These occupations include railway and road workers, airpo ...

Glow Stick
A glow stick, also known as a light stick, chem light, light wand, light rod, and rave light, is a self-contained, short-term light-source. It consists of a translucent plastic tube containing isolated substances that, when combined, make light through chemiluminescence. The light cannot be turned off and can be used only once. The used tube is then thrown away. Glow sticks are often used for recreation, such as for events, camping, outdoor exploration, and concerts. Glow sticks are also used for light in military and emergency services applications. Industrial uses include marine, transportation, and mining. History Bis(2,4,5-trichloro-6-(pentyloxycarbonyl)phenyl)oxalate, trademarked "Cyalume", was invented in 1971 by Michael M. Rauhut, of American Cyanamid, based on work by Edwin A. Chandross and David Iba Sr. of Bell Labs. Other early work on chemiluminescence was carried out at the same time, by researchers under Herbert Richter at China Lake Naval Weapons Center. Sever ...

Stop Sign
A stop sign is a traffic sign designed to notify drivers that they must come to a complete stop and make sure the intersection (road), intersection (or level crossing, railroad crossing) is safely clear of vehicles and pedestrians before continuing past the sign. In many countries, the sign is a red octagon with the word ''STOP'', in either English, the national language of that particular country, or both, displayed in white or yellow. The Vienna Convention on Road Signs and Signals also allows an alternative version: a red circle with a red inverted triangle with either a white or yellow background, and a black or dark blue ''STOP''. Some countries may also use other types, such as Japan's inverted red triangle stop sign. Particular regulations regarding appearance, installation, and compliance with the signs vary by some jurisdictions.

Traffic Sign
Traffic signs or road signs are signs erected at the side of or above roads to give instructions or provide information to road users. The earliest signs were simple wooden or stone milestones. Later, signs with directional arms were introduced, for example the fingerposts in the United Kingdom and their wooden counterparts in Saxony. With traffic volumes increasing since the 1930s, many countries have adopted pictorial signs or otherwise simplified and standardized their signs to overcome language barriers, and enhance traffic safety. Such pictorial signs use symbols (often silhouettes) in place of words and are usually based on international protocols. Such signs were first developed in Europe, and have been adopted by most countries to varying degrees. International conventions International conventions such as Vienna Convention on Road Signs and Signals and Geneva Convention on Road Traffic have helped to achieve a degree of uniformity in traffic signing in various ...

One characteristic of a whistle is that it creates a pure, or nearly pure, Musical tone, tone. The conversion of flow energy to sound comes from an interaction between a solid material and a fluid stream. The forces in some whistles are sufficient to set the solid material in motion.
