Lightguard Systems
Lightguard Systems is a California traffic safety device company known for developing “Smart Crosswalk”, the earliest pedestrian safety system to use embedded pavement flashing-light systems. Founding Lightguard Systems Inc. produces Lighted Crosswalk Systems invented by its founder, Michael Harrison. Inspired by a series of fatal pedestrian traffic incidents in Santa Rosa, California in 1991, Harrison developed the first LightGuard system as a safety aid for installation at pedestrian crossings and started LightGuard Systems to produce them. A commercial pilot, Harrison was inspired by the flashing lights used as runway beacon lights. He applied this principle for crosswalk visibility and founded LightGuard Systems to produce and install systems based on the technology he developed. Lighted Crosswalk System “The experimental ‘Crosswalk Warning System’, also known as the ‘LightGuard System’ or the ‘Santa Rosa Lights’ consists of warning lights housed in a unit wh ...

Corporation
A corporation is an organization—usually a group of people or a company—authorized by the state to act as a single entity (a legal entity recognized by private and public law "born out of statute"; a legal person in legal context) and recognized as such in law for certain purposes. Early incorporated entities were established by charter (i.e. by an ''ad hoc'' act granted by a monarch or passed by a parliament or legislature). Most jurisdictions now allow the creation of new corporations through registration. Corporations come in many different types but are usually divided by the law of the jurisdiction where they are chartered based on two aspects: by whether they can issue stock, or by whether they are formed to make a profit. Depending on the number of owners, a corporation can be classified as ''aggregate'' (the subject of this article) or '' sole'' (a legal entity consisting of a single incorporated office occupied by a single natural person). One of the most att ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Traffic Safety
Road traffic safety refers to the methods and measures used to prevent road users from being killed or seriously injured. Typical road users include pedestrians, cyclists, motorists, vehicle passengers, horse riders, and passengers of on-road public transport (mainly buses and trams). Best practices in modern road safety strategy: As sustainable solutions for classes of road safety have not been identified, particularly low-traffic rural and remote roads, a hierarchy of control should be applied, similar to classifications used to improve occupational safety and health. At the highest level is sustainable prevention of serious injury and death crashes, with sustainable requiring all key result areas to be considered. At the second level is real-time risk reduction, which involves providing users at severe risk with a specific warning to enable them to take mitigating action. The third level is about reducing the crash risk which involves applying the road-design standards ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embedded Pavement Flashing-light System
An embedded flashing-light system or an in-pavement flashing-light system is a type of device that is used at existing or new pedestrian crosswalks to warn drivers of oncoming pedestrian traffic. The device usually consists of LED lights that are embedded into the roadway alongside the crosswalk and are oriented to face oncoming traffic. When a pedestrian approaches the crosswalk, the system is activated and the LED lights begin to flash simultaneously. These lights are programmed to flash for a period of time that is sufficient for an average pedestrian to cross. History The concept for an embedded pavement flashing light system was conceived by pilot Michael Harrison in Santa Rosa, California, in 1992 after a friend was involved in a pedestrian accident. He based it on his experience with airport runway lights embedded in the pavement, Mr. Harrison went on to found Lightguard Systems. Types There are two different types of embedded pavement flashing light systems, passive and ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crosswalk
A pedestrian crossing (or crosswalk in American English) is a place designated for pedestrians to cross a road, street or avenue. The term "pedestrian crossing" is also used in the Vienna and Geneva Conventions, both of which pertain to road signs and road traffic. Marked pedestrian crossings are often found at intersections, but may also be at other points on busy roads that would otherwise be too unsafe to cross without assistance due to vehicle numbers, speed or road widths. They are also commonly installed where large numbers of pedestrians are attempting to cross (such as in shopping areas) or where vulnerable road users (such as school children) regularly cross. Rules govern usage of the pedestrian crossings to ensure safety; for example, in some areas, the pedestrian must be more than halfway across the crosswalk before the driver proceeds. Signalised pedestrian crossings clearly separate when each type of traffic (pedestrians or road vehicles) can use the crossing. U ...

Commercial Pilot
A commercial pilot licence (CPL) is a type of pilot licence that permits the holder to act as a pilot of an aircraft and be paid for their work. Different licenses are issued for the major aircraft categories: airplanes, airships, balloons, gliders, gyroplanes and helicopters. Depending on the jurisdiction these may all be on the same document. A CPL will typically have no expiry date. However, a valid medical certificate and valid rating will be required to use it. A pilot's ratings may be listed on the licence, including the types of aircraft that can be flown (single-engine or multiengine), whether flight under instrument flight rules is allowed (instrument rating), and whether instructing and examining of trainee pilots can be done (instructor or examiner rating). Requirements The basic requirements to obtain the license and the privileges it confers are agreed internationally by the International Civil Aviation Organization (ICAO). However the actual implementation varies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beacon
A beacon is an intentionally conspicuous device designed to attract attention to a specific location. A common example is the lighthouse, which draws attention to a fixed point that can be used to navigate around obstacles or into port. More modern examples include a variety of radio beacons that can be read on radio direction finders in all weather, and radar transponders that appear on radar displays. Beacons can also be combined with semaphoric or other indicators to provide important information, such as the status of an airport, by the colour and rotational pattern of its airport beacon, or of pending weather as indicated on a weather beacon mounted at the top of a tall building or similar site. When used in such fashion, beacons can be considered a form of optical telegraphy. For navigation Beacons help guide navigators to their destinations. Types of navigational beacons include radar reflectors, radio beacons, sonic and visual signals. Visual beacons range from sma ...
