Other colors are possible too, with the 532 nm green laser being the most common alternative. [4][6][10] The Pointer's short and fine coat makes the breed well suited to working on grouse moors during the summer months but makes them particularly susceptible to feeling cold during wet and cold weather. (Arizona Revised Statutes §13-1213) [70], On 30 April 2010, Clint Jason Brenner, 36, of Prescott, Arizona, was found guilty of two counts of endangerment, each a class 6 felony, and it was also found that each was a dangerous offense, for shining a handheld laser pointer at an Arizona Department of Public Safety helicopter in December 2009. They are more complex than standard red laser pointers, because laser diodes are not commonly available in this wavelength range. Dubbed "Burning Lasers", these are designed to burn through light plastics and paper, and can have very similar external appearances to their low-power counterparts. We're an exclusive carrier of Pointer Brand, presenting the best the brand has to offer, and thus, some of the finest workwear to ever exist. Because of the higher neodymium harmonic used, and the lower efficiency of frequency-doubling conversion, the fraction of IR power converted to 473 nm blue laser light in optimally configured DPSS modules is typically 10–13%, about half that typical for green lasers (20–30%). In early 2010 "Blu-ray" (actually violet) laser pointers at 405 nm went on sale. [10], The Pointer is a medium-sized, athletic breed that is built for both endurance and speed. King Mfg. In September 2005 handheld blue laser pointers at 473 nm became available.   The Pointer, often called the English Pointer, is a breed of dog developed as a gun dog. What poses a special hazard for this unfiltered IR output is its presence in conjunction with laser safety goggles designed to only block the visible wavelengths of the laser. Hundreds of protesters gathered outside the dome of Hong Kong's Space Museum to put on a “laser show” to denounce police's claims that these laser pointers were offensive weapons. The difference is that the type of &pmessage is char** - pointer to pointer to char, and the type of &amessage is char(*)[16] - pointer to array of 16 chars. The low-cost availability of infrared (IR) diode laser modules of up to 1000 mW (1 watt) output has created a generation of IR-pumped, frequency doubled, green, blue, and violet diode-pumped solid-state laser pointers with visible power up to 300 mW. Some militaries use lasers to mark targets at night for aircraft. The Pointer, sometimes called the English Pointer, is a medium-sized breed of pointing dog developed in England. [63], To assist with enforcement, police helicopters use GPS and thermal imaging camera, together with dog teams on the ground, to help locate the offender; the discarded warm laser pointer is often visible on the thermal camera, and its wavelength can be matched to that recorded by an event recorder in the helicopter. En la línea de marcas de GM, Pontiac era una marca intermedia con un enfoque hacia los modelos deportivos y de rendimiento a un precio razonable. It is still allowed to trade Class 2 (< 1 mW) laser pointers proper, but they have to meet requirements regarding warnings and instructions for safe use in the manual. "Michigan Legislature - Section 750.224a". [1][2][5][15] The Pointer is the most popular pointing dog breed used by sporting estates in the United Kingdom and commercial shooting preserves in the United States, they are also the most popular and successful pointing breed used in pointing dog trials in both countries. Once in England, they were crossed with local dog breeds to improve the breed's hunting abilities. According to U.S. Food and Drug Administration (FDA) regulations, more powerful lasers may not be sold or promoted as laser pointers. ball pens, key chains, business gifts, devices that will end up in children's possession, parts of toys, etc.). Lemon & white, orange & white, liver & white and black & white; tri-colour and self-colour are known. Pre-Owned. Armed police have drawn their weapons in such circumstances.[1]. This invisible IR component causes a degree of extra potential hazard in these devices when pointed at nearby objects and people. Laser alignment is much easier than aligning through using the eyepiece. [citation needed], Laser pointers are used in robotics, for example, for laser guidance to direct the robot to a goal position by means of a laser beam, i.e. Recent popularity of the high-power version of these 447 nm pointers, which also have improved optics for better collimation and lower divergence, rivals the hazards associated with the use of these portable devices by persons of questionable intention and cost has diminished to be competitive with DPSS green lasers wavelengths. By removing counterfeits and frauds, we help to reinforce a stable and safe exchange of goods and services, advocating for both producers and consumers. In rare cases a dot of light from a red laser pointer may be thought to be due to a laser gunsight. He denied that it was a reason for dropping the ball, but despite this the MCG decided to keep an eye out for the laser pointers. [80] Colombia is the first country in South America to regulate the marketing of these products. Fong said he would use the pointers for stargazing, but police described them as “laser guns” whose beams could cause eye injuries. Co., to explore partnerships, or just to experience what it's like in our factory. Studies in the early twenty-first century found that the risk to the human eye from accidental exposure to light from commercially available class IIIa laser pointers having powers up to 5 mW seemed rather small; however, prolonged viewing, such as deliberate staring into the beam for 10 or more seconds, can cause damage. Those whose professions require the use of a laser can apply for an exemption. He burned his retinas near the macula, the area where most of a persons central vision is located. [43] Despite the disclaimers, such lasers are frequently sold in packaging resembling that for laser pointers. They most commonly emit a beam at 473 nm, which is produced by frequency doubling of 946 nm laser radiation from a diode-pumped Nd:YAG or Nd:YVO4 crystal (Nd-doped crystals usually produce a principal wavelength of 1064 nm, but with the proper reflective coating mirrors can be also made to lase at other "higher harmonic" non-principal neodymium wavelengths). Related wikiHows. [4][7], The earliest recorded mentions of Pointers in England date from the early 18th century. [71][72], On 2 November 2009, Dana Christian Welch of Southern California was sentenced to 2.5 years in a federal prison after being found guilty of shining a hand-held laser light into the eyes of two pilots landing Boeing jets at John Wayne Airport. 1. The first public demonstration of a mouse controlling a computer system was in 1968. El Pòinter (de l' anglès to point, apuntar) és un gos de mostra, originari d' Anglaterra i considerat un dels millors perdiguers, indicant la presència de la presa apuntant-la amb el cap i amb una postura corporal immòbil i tensa, normalment amb una extremitat davantera aixecada. [5] John Gay mentions Pointers being used to hunt partridge in his 1713 poem Rural sports, and Peter Tillemans produced a painting of the Duke of Kingston-upon-Hull's kennel of pointers in 1725. [13] Green laser is visible at night due to Rayleigh scattering and airborne dust,[14] allowing someone to point out individual stars to others nearby. Since 1913, Pointer has been a name synonymous with American quality, durability, and timeless style. The Pointer is an athletic and graceful kind of dog. Unlike pointers, these usually produce low-power highly divergent beams to ensure eye safety. In mid-to-late 2011, 405 nm blue-violet laser diode modules with an optical power of 250 mW, based on GaN violet laser diodes made for Blu-ray disc readers, had reached the market from Chinese sources for prices of about US$60 including delivery.[11]. A needle-like component of a timepiece or measuring device that indicates the time or the current readingof the device. Lasers classified as pointers are intended to have outputs less than 5 mW total power (Class 3R). The orientation of the crystals must be matched, as they are both anisotropic and the Nd:YVO4 outputs polarized light. Elton Tyron Brand (born March 11, 1979) is an American former professional basketball player and the current general manager of the Philadelphia 76ers of the National Basketball Association (NBA).

The eye will usually react to the higher-powered visible light; however, in higher power DPSS lasers the IR laser output can be significant. [1][5] Additionally, compared to the European pointing breeds the Pointer is typically faster when working and quarters further in search for game. Laser pointers, with their very long range, are often maliciously shone at people to distract or annoy them, or for fun. Lasers have also become a popular plaything for pets such as cats, ferrets and dogs, whose natural predatory instincts are triggered by the moving laser and will chase it and/or try to catch it as much as possible, but obviously never succeed. The laser pointer ban only applies to hand-held battery-powered laser devices and not laser modules. Either way, their clothing been able to transcend time … Such pointers, particularly in the green-light output range, are used as astronomical-object pointers for teaching purposes. Pointer nebo anglický pointer je plemeno psa podle FCI č.1, skupina 7: ohaři, 2. sekce - britští a irští ohaři, původem z Anglie.Je to plemeno loveckého psa, které se vyznačuje vrozenou chutí do práce. Descripción y reglas. That is because such a complex process may require temperature stabilizers and active cooling, which can't be mounted into a small-sized host. [5][9][10] In the book he notes that he did not find any truly convincing evidence of Spanish Pointers being the foundation stock of the Pointer but still concludes on the basis of all evidence that it is the most likely history. A laser pointer or laser pen is a small handheld device with a power source (usually a battery) and a laser diode emitting a very narrow coherent low-powered laser beam of visible light, intended to be used to highlight something of interest by illuminating it with a small bright spot of colored light. La gama Pointer … [7][14] The Pointer has a very distinctive head with a slightly dished face and elevated nose, a raised brow, and wide nostrils, their ears are hanging and lie close to the face, are high set, medium-sized, and slightly pointed. Some blue diodes are capable of very high power; such as Nichia's NDB7K75 diode, which can continuously output over 5 watts if overdriven. This is done to ensure that "friendly" and "enemy" targets are not mistaken. . These were DPSS-type frequency-doubled devices. The output of laser pointers available to the general public is limited (and varies by country) in order to prevent accidental damage to the retina of human eyes. After the match the Algerian Football Federation was fined CHF50,000 (approx. 5. Yellow-orange laser pointers, at 593.5 nm, later became available. El Volkswagen Pointer, fue un automóvil de turismo del segmento C, de carrocería tipo berlina hatchback, producido entre los años 1994 y 1996 por el holding Autolatina para el mercado regional del Mercosur. [40] At the 2014 World Cup during the final group stage match between Algeria and Russia a green laser beam was directed on the face of Russian goalkeeper Igor Akinfeev. Others involved in activities where dazzling or distraction are dangerous are also a concern. [38] In 2008 laser pointers were aimed at players' eyes in a number of sport matches worldwide. Fong was released unconditionally two days later. This can be one of the most accurate ways of marking targets. Dog ( domestic dog) The Pointer, sometimes called the English Pointer, is a medium-sized breed of pointing dog developed in England. Laser pointers available for purchase online can be capable of significantly higher power output than the pointers typically available in stores. As a result, the boy has almost immediately lost 75% of his vision, with little hope of recovery. Other charges that could be laid include mischief and assault.[56]. The least expensive laser pointers use a deep-red laser diode near the 650 nm wavelength. [4][5] The introduction of Greyhound blood resulted in the modern Pointer being a much finer dog with a comparatively tucked-up loin, tighter lips and low-set tail, more akin to that of the Greyhound than European pointer breeds. pointer (plural pointers) 1. [66] Also, any laser with class higher than IIIa (more than 5 milliwatts) requires a key-switch interlock and other safety features. Roy played six seasons in the National Basketball Association for the Portland Trail Blazers and Minnesota Timberwolves. Though the IR from a DPSS laser is less collimated, the typical neodymium-doped crystals in such lasers do produce a true IR laser beam. As of 2010 the penalty could be five years' imprisonment.[42]. For high output power, BBO crystals are used as frequency doublers; for lower powers, KTP is used. Orange laser pointers emitting at 593.5 nm became available in the last few years[when?]. [14][17] Known inherited conditions that have been found in the breed include hip dysplasia, elbow dysplasia, patella luxation, hereditary sensory neuropathy, spinal muscle atrophy, X-linked cerebellar ataxia and deafness. Shop Pointer Brand on Backcountry. The old sign still hangs in the factory, and the Pointer dog's likeness is on every pointer product. In addition to the safety hazards of unfiltered IR from DPSS lasers, the IR component may be inclusive of total output figures in some laser pointers. Irresponsible use of laser pointers is often frowned upon by members of the laser projector community who fear that their misuse may result in legislation affecting lasers designed to be placed within projectors and used within the entertainment industry. They proved to be useful in this type of business because of their accuracy, which made them significant time-savers. This lasing action is due to an electronic transition in the fluorescent neodymium ion, Nd(III), which is present in all of these crystals. Usually, an infrared filter behind the output coupler removes IR radiation from the output beam, though this is sometimes omitted, and the assembly ends in a collimator lens. Autolatina tenía como objetivo producir y comercializar una serie de desarrollos automotrices focalizados a la zona del Mercosur, los cuales conjugaban en su estructura las tecnologías de las marcas Volkswagen y Ford, a las que representaba. [16], The Pointer is considered a generally healthy breed with a life expectancy of 13–14 years, The Kennel Club does not recommend any genetic or screening tests be conducted for the breed. Pointer Brand logo T Shirt White RN 14916 Men's size Large Heavy Weight Sz L USA Top Rated Seller. The highest measured power output was 66.5 milliwatts; more than 10 times the limit. The Nd:YVO4 or other Nd-doped crystal is coated on the diode side with a dichroic beam splitter, that reflects at 1064 nm and transmits at 808 nm. These DPSS laser wavelengths are usually more exotic, more expensive, and generally manufactured with higher quality components, including filters, unless they are put into laser pointer style pocket-pen packages. (Scene opens up showing the sun, the pans down to the Flynn-Fletcher house. National Institute of Standards and Technology tests[20] conducted on laser pointers labeled as Class IIIa or 3R in 2013 showed that about half of them emitted power at twice the Class limit, making their correct designation Class IIIb – more hazardous than Class IIIa. There have been many incidents regarding, in particular, aircraft, and the authorities in many countries take them extremely seriously. [59] From 1 January 2014 it is necessary to have a special permit in order to own a laser pointer with a classification of 3R, 3B or 4, i.e. As coach: Naismith National HS Coach of the Year Career statistics Points6,136 Rebounds1,388 Assists1,517 Stats at NBA.com Stats at Basketball-Reference.com Brandon Dawayne Roy is an American basketball coach and former player. The first red laser pointers released in the early 1980s were large, unwieldy devices that sold for hundreds of dollars. Despite legislation limiting the output of laser pointers in some countries, higher-power devices are currently produced in other regions and are frequently imported by customers who purchase them directly via Internet mail order. Pointer Brand has been making Chore Coats and other workwear in Bristol, Tennessee since 1913. [26][27] Because of their high power, many online retailers have warned high-power laser pointer users not to point them at humans or animals. During the 2019–20 Hong Kong protests, laser pointers are being used by protesters to confuse police officers and scramble facial recognition cameras. [13] The breed usually weighs between 20 and 34 kilograms (45 and 75 lb), with dogs weighing 25 to 34 kilograms (55 to 75 lb) and bitches 20 to 29 kilograms (45 to 65 lb). [10], Some vendors are now selling collimated diode blue laser pointers with measured powers exceeding 1,500 mW. Trading of Class 3 and higher laser pointers is not allowed. Olympique Lyonnais was fined by UEFA because of a laser pointer beam aimed by a Lyon fan at Cristiano Ronaldo. Thus, all laser pointers will have a warning label, stating the user not to point it at a person or animal's eyes. Pointer Brand Protection specializes in global brand protection solutions. 2. Pointer - world dog show 2010.jpg 1,200 × 1,160; 210 KB Pointer 2 Moletai May 2014.jpg 576 × 720; 113 KB Pointer and Irish Setter Portrait.jpg 791 × 438; 204 KB The complexity of this process makes these laser pointers inherently unstable and inefficient, with their outputs ranging from 1 mW to about 10 mW, greatly varying with temperature and usually mode-hopping if they get too hot or too cold. [4][5], A second less commonly held belief is a form of Pointer that was present in England, much earlier than the introduction of the Spanish Pointer, and that they were used from medieval times to indicate the location of hares which were subsequently coursed by greyhounds or caught by hawks; it is held that these dogs were subsequently heavily influenced by the introduction of imported European pointer blood. This intuitive interface simplifies directing the robot while visual feedback improves the positioning accuracy and allows for implicit localization.[15][16]. [47][48] In Western Australia, regulatory changes have classified laser pointers as controlled weapons and demonstration of a lawful reason for possession is required. There are reports in the medical literature documenting permanent injury to the macula and the subsequently permanent loss of vision after laser light from laser pointer being shone to human's eyes. Pointer puede referirse a: Un perro de muestra, por su nombre en idioma inglés. Democratic Party lawmaker and lawyer James To Kun-sun criticized the police for abuse of power. A high-powered green laser pointer bought over the Internet was reported in 2010 to have caused a decrease of visual acuity from 6/6 to 6/12 (20/20 to 20/40); after two months acuity recovered to 6/6, but some retinal damage remained. Pointer Brand has an extensive history and has been around for over a century crafting classic workwear garments. The Japanese company Nichia controlled 80% of the blue-laser-diode market in 2006. The popular belief is that the Pointer descends from the Old Spanish Pointer that was brought to England from Spain with returning soldiers at the beginning of the 18th century. Astronomical observatories use a specially tuned dye laser at 589.2 nm (yellow) to create a laser guide star for use with astronomical adaptive optics. As with infrared-driven green laser pointers above, such devices are able to pop balloons and light matches, but this is as a result of an unfiltered high-power infrared component in the beam. With the steady improvement of firearms throughout the 18th and 19th centuries, faster and more agile dogs were sought so Greyhounds were increasingly introduced to add speed. Some higher-powered laser pointers project a visible beam via scattering from dust particles or water droplets along the beam path. over 1 mW. [64], In 2014, a Flintshire 22-year-old was convicted of recklessly endangering the lives of a police search helicopter crew through the use of such a device, and awarded a five-month suspended sentence. These higher-powered lasers are often packaged in the same pointer-style housings as regular laser pointers, and usually lack the IR filters found in professional high-powered DPSS lasers, because of costs and additional efforts needed to accommodate them. C $34.92. [28][29][30][31], The UK Health Protection Agency warns against the higher-power typically green laser pointers available over the Internet, with power output of up to a few hundred milliwatts, as "extremely dangerous and not suitable for sale to the public."[32].
