Reversing (vehicle Maneuver)
Reversing (also known as backing up) is the process of driving a vehicle in the reverse direction in order to maneuver. Rear view mirrors are somewhat standard equipment for this endeavor. Reversing a vehicle is used as an intermediate step to complete a three point turn, J-turn, parallel park, or similar maneuver. These moves are used with the goal of positioning the vehicle in a specific way under certain space restrictions, that would not be possible to achieve whilst only moving forward. Extremely large or luxury vehicles may have in addition technical aids such as backup cameras. Many industrial vehicles such as fork lifts automatically activate a repetitive warning beep whilst reversing. In the UK, trucks (lorries) may be fitted with warning devices which repeatedly announce "Attention: this vehicle is reversing", or the equivalent phrase in Welsh: "Mae'r cerbyd yn mynd yn ôl". Harmonization of reverse warning sound of vehicles is planned by an adopted UNECE regul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Nations Economic Commission For Europe
The United Nations Economic Commission for Europe (ECE or UNECE) is an intergovernmental organization or a specialized body of the United Nations. The UNECE is one of five regional commissions under the jurisdiction of the United Nations Economic and Social Council. It was established in 1947 in order to promote economic cooperation and integration among its member states. The commission is composed of 56 member states, most of which are based in Europe, as well as a few outside Europe. Its transcontinental Eurasian or non-European member states include: Armenia, Azerbaijan, Canada, Cyprus, Georgia, Israel, Kazakhstan, Kyrgyzstan, the Russian Federation, Tajikistan, Turkey, Turkmenistan, the United States and Uzbekistan. History The commission was first proposed in London in the summer of 1946 by the Temporary Subcommission on the Reconstruction of Devastated Areas. The commission was established by the Economic and Social Council on 28 March 1947 in order to "Initiate and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vehicle Blind Spot
A blind spot in a vehicle or vehicle blind spot is an area around the vehicle that cannot be directly seen by the driver while at the controls, under existing circumstances. In transport, driver visibility is the maximum distance at which the driver of a vehicle can see and identify prominent objects around the vehicle. Visibility is primarily determined by weather conditions (see visibility) and by a vehicle's design. The parts of a vehicle that influence visibility include the windshield, the dashboard and the pillars. Good driver visibility is essential to safe road traffic. Conditions for blind spots Blind spots exist in a wide range of vehicles: aircraft, cars, buses, trucks, agricultural equipment, heavy equipment, boats, ships, trams and trains. Blind spots may occur in the front of the driver when the A-pillar (also called the windshield pillar), side-view mirror, or interior rear-view mirror block a driver's view of the road. Behind the driver, cargo, headrests, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Side-view Mirror
A side-view mirror (or side mirror), also known as a door mirror and often (in the UK) called a wing mirror, is a mirror placed on the exterior of motor vehicles for the purposes of helping the driver see areas behind and to the sides of the vehicle, outside the driver's peripheral vision (in the " blind spot"). Almost all modern cars mount their side mirrors on the doors—normally at the A-pillar—rather than the wings (the portion of the body above the wheel well). The side mirror is equipped for manual or remote vertical and horizontal adjustment so as to provide adequate coverage to drivers of differing height and seated position. Remote adjustment may be mechanical by means of bowden cables, or may be electric by means of geared motors. The mirror glass may also be electrically heated and may include electrochromic dimming to reduce glare to the driver from the headlamps of following vehicles. Increasingly, the side mirror incorporates the vehicle's turn signal rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rear-view Mirror
A rear-view mirror (or rearview mirror) is a, usually plane mirror, flat, mirror in automobiles and other vehicles, designed to allow the driver to see rearward through the vehicle's rear window (rear windshield). In cars, the rear-view mirror is usually affixed to the top of the windshield on a double-swivel mount allowing it to be adjusted to suit the height and viewing angle of any driver and to swing harmlessly out of the way if impacted by a vehicle occupant in a Traffic collision, collision. The rear-view mirror is augmented by one or more Wing mirror, side-view mirrors, which serve as the only rear-vision mirrors on trucks, motorcycles and bicycles. History Early use of fixed mirrors was described as early as 1906, with a trade magazine noting mirrors for showing what is coming behind were now popular on closed bodied automobiles, and were likely to be widely adopted in a short time. The same year, a Mr. Bilal Ghanty from France patented a "''Warning mirror for au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parking Sensor
Parking sensors are proximity sensors for road vehicles designed to alert the driver of obstacles while parking. These systems use either electromagnetic or ultrasonic sensors. Ultrasonic systems These systems feature Ultrasonic sensor, ultrasonic proximity detectors to measure the distances to nearby objects via sensors located in the front and/or rear Bumper (automobile), bumper fascias or visually minimized within adjacent grills or recesses. The sensors emit acoustic pulses, with a control unit measuring the return interval of each reflected signal and calculating object distances. The system in turns warns the driver with acoustic tones, the frequency indicating object distance, with faster tones indicating closer proximity and a continuous tone indicating a minimal pre-defined distance. Systems may also include visual aids, such as LED or LCD readouts to indicate object distance. A vehicle may include a vehicle pictogram on the car's infotainment screen, with a representat ...

Blind Spot Monitor
The blind spot monitor or blind-spot monitoring is a vehicle-based sensor device that detects other vehicles located to the driver’s side and rear. Warnings can be visual, audible, vibrating, or tactile. Blind spot monitors may do more than monitor the sides and rear of the vehicle. They may also include "Rear Cross-Traffic Alert", "which alerts drivers backing out of a parking space when traffic is approaching from the sides." History If side view mirrors on a car are adjusted properly, there is no blind spot on the sides. This method was first documented by George Platzer in a 1995 paper presented to the Society of Automotive Engineers, but the method is frequently overlooked in driver's education classes and takes some getting used to. Untrained drivers tend to adjust the side mirrors too far in, so they can see the sides of their own vehicle, but cannot see vehicles traveling alongside in adjacent lanes. Calculated elimination of blind spots by trained drivers is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backup Camera
A backup camera (also called a reversing camera or rear-view camera) is a video camera specifically designed to be attached to the rear of a vehicle to aid in Reversing (vehicle maneuver), reversing and reduce the rear Blind spot (vehicle), blind spot. The rear blind spot has been described as a "killing zone" due to the accidents it contributes to. Backup cameras are usually connected to the vehicle's head unit display. A common variant is a surround-view system, which assembles a synthetic but positionally accurate top-down view of the vehicle and its surroundings. Backup cameras have been regulated by law in Canada and the United States since 2018. Since May of that year, backup cameras have been required on all new vehicles sold in the United States. Function The design of a backup camera is distinct from other cameras because the image is horizontally flipped to produce a mirror image. This is necessary because the camera and the driver face opposite directions; without this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TheGuardian
''The Guardian'' is a British daily newspaper. It was founded in Manchester in 1821 as ''The Manchester Guardian'' and changed its name in 1959, followed by a move to London. Along with its sister paper, '' The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust Limited. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators. Profits are reinvested in its journalism rather than distributed to owners or shareholders. It is considered a newspaper of record in the UK. The editor-in-chief Katharine Viner succeeded Alan Rusbridger in 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Driving
Driving is the controlled operation and movement of a land vehicle, including cars, motorcycles, trucks, and buses. A driver's permission to drive on public highways is granted based on a set of conditions being met, and drivers are required to follow the established Traffic code, road and traffic laws in the location they are driving. The word "driving" has etymology dating back to the 15th century. Its meaning has changed from primarily driving working animals in the 15th century to automobiles in the 1800s. Driving skills have also developed since the 15th century, with physical, mental and safety skills being required to drive. This evolution of the skills required to drive have been accompanied by the introduction of driving laws which relate not only to the driver but also to the driveability of a car. The term "driver" originated in the 15th century, referring to the occupation of driving working animals such as pack or draft horses. It later applied to electric railway d ...

Welsh Language
Welsh ( or ) is a Celtic languages, Celtic language of the Brittonic languages, Brittonic subgroup that is native to the Welsh people. Welsh is spoken natively in Wales by about 18% of the population, by some in England, and in (the Welsh colony in Chubut Province, Argentina). It is spoken by smaller numbers of people in Canada and the United States descended from Welsh immigrants, within their households (especially in Nova Scotia). Historically, it has also been known in English as "British", "Cambrian", "Cambric" and "Cymric". The Welsh Language (Wales) Measure 2011 gave the Welsh language official status in Wales. Welsh and English are ''de jure'' official languages of the Senedd (the Welsh parliament), with Welsh being the only ''de jure'' official language in any part of the United Kingdom, with English being merely ''de facto'' official. According to the 2021 United Kingdom census, 2021 census, the Welsh-speaking population of Wales aged three or older was 538,300 ( ...
