Unicycle
A unicycle is a vehicle that touches the ground with only one wheel. The most common variation has a frame with a saddle, and has a pedal-driven direct drive. A two speed hub is commercially available for faster uncycling. Unicycling is practiced professionally in circuses, by street performers, in festivals, and as a hobby. Unicycles have also been used to create new sports such as unicycle hockey. In recent years, unicycles have also been used in activities similar to mountain biking or trials. US patents for single-wheeled 'velocipedes' were published in 1869 by Frederick Myers and in 1881 by Battista Scuri.
Suspension (vehicle)
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both roadholding/handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear.
Unicycle trials
Unicycle trials is a form of unicycling which involves participants attempting to ride a unicycle over obstacles without any part of the rider touching the ground. The obstacles traversed can be set up specifically for the purpose of unicycle trials, but are often walls, railings, ledges and other "street furniture" found in an urban environment. The sport is derived from (or at least inspired by) bike trials and motorcycle trials. Obstacles are traversed using various moves. Hopping is achieved by suddenly forcing the unicycle pedals downwards while holding the seat, the reactive forces resulting from the compression of the tyre lift the unicycle into the air.
Electric bicycle laws
Many countries have enacted electric bicycle laws to regulate the use of electric bicycles. Countries such as the United States and Canada have federal regulations governing the safety requirements and standards of manufacture. Other countries like the signatories of the European Union have agreed to wider-ranging legislation covering use and safety of their term EPAC (electric pedal-assisted cycles). However, confusion remains regarding the various laws involving electric bicycles. This stems from the fact that while some countries have national regulations, the legality of road use is left to states and provinces, and then complicated further by municipal laws and restrictions.
Three-wheeler
A three-wheeler is a vehicle with three wheels. Some are motorized tricycles, which may be legally classed as motorcycles, while others are tricycles without a motor, some of which are human powered vehicles and animal powered vehicles. Many three-wheelers which exist in the form of motorcycle-based machines are often called trikes and often have the front single wheel and mechanics similar to that of a motorcycle and the rear axle similar to that of a car. Often such vehicles are owner-constructed using a portion of a rear-engine, rear-drive Volkswagen Beetle in combination with a motorcycle front end.
Limited-slip differential
A limited-slip differential is a type of differential that allows its two output shafts to rotate at different speeds but limits the maximum difference between the two shafts. In an automobile, such limited-slip differentials are sometimes used in place of a standard differential, where they convey certain dynamic advantages, at the expense of greater complexity. In 1932, Ferdinand Porsche designed a Grand Prix racing car for the Auto Union company. The high power of the design caused one of the rear wheels to experience excessive wheel spin at any speed up to . In 1935, Porsche commissioned the engineering firm ZF to design a limited-slip differential to improve performance.
Personal transporter
A personal transporter (also personal light electric vehicle, personal mobility device, electric rideable ) is a class of compact, portable, electrically powered electric vehicle for transporting an individual at speeds that don't normally exceed , which includes electric skateboards, electric kick scooters, self-balancing unicycles and Segways. Made possible by recent advances in vehicle battery and motor-control technologies, legislators are in the process of determining how these devices should be classified, regulated and accommodated during a period of rapid innovation. Excluded from this legal category are electric bicycles (that are considered to be a type of bicycle), electric motorbikes and scooters (that are treated as a type of scooter) and powered mobility aids with 3 or 4 wheels on which the rider sits (which fall within regulations covering powered mobility scooters).

List of prolific inventors
Thomas Alva Edison was widely known as the America's most prolific inventor, even after his death in 1931. He held a total of 1,093 U.S. patents (1,084 utility patents and 9 design patents). In 2003, he was passed by Japanese inventor Shunpei Yamazaki. On February 26, 2008, Yamazaki was passed by Australian inventor Kia Silverbrook. Yamazaki passed Silverbrook in 2017. Inventors with 200 or more worldwide utility patents are shown in the following table. While in many cases this is the number of utility patents granted by the United States Patent and Trademark Office, it may include utility patents granted by other countries, as noted by the source references for an inventor.
Thomas Edison
Thomas Alva Edison (February 11, 1847October 18, 1931) was an American inventor and businessman, who has been described as America's greatest inventor. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and the long-lasting, practical electric light bulb. Dubbed "The Wizard of Menlo Park", he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrial research laboratory.
Heather Kalenchuk
Heather Mary Yvonne Kalenchuk (born Heather Seeley, March 14, 1984) is a Canadian curler from Regina, Saskatchewan. She previously played lead for Amber Holland. Born in Edmonton, Alberta, Kalenchuk won the 2002 provincial high school mixed championship. In 2003, 2004 and 2005, she played in the provincial junior championship, but did not win. In 2005 and 2007, Kalenchuk played at the University national championships. In 2008, the team won their only Grand Slam event, the 2008 Players' Championships. In 2009 the team would earn a spot in the Canadian Olympic Curling Trials, after defeating Marie-France Larouche in the C Qualifier.

Apple Inc. v. Samsung Electronics Co.
Apple Inc. v. Samsung Electronics Co., Ltd. was the first of a series of ongoing lawsuits between Apple Inc. and Samsung Electronics regarding the design of smartphones and tablet computers; between them, the companies made more than half of smartphones sold worldwide as of July 2012. In the spring of 2011, Apple began litigating against Samsung in patent infringement suits, while Apple and Motorola Mobility were already engaged in a patent war on several fronts. Apple's multinational litigation over technology patents became known as part of the mobile device "smartphone patent wars": extensive litigation in fierce competition in the global market for consumer mobile communications.
War of the currents
The war of the currents (sometimes called battle of the currents) was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s. It included commercial competition, a debate over electrical safety, and a media/propaganda campaign that grew out of it, with the main players being the direct current (DC) based Edison Electric Light Company and the alternating current (AC) based Westinghouse Electric Company. It took place during the introduction and rapid expansion of the alternating current standard (already in use and advocated by several US and European companies) and its eventual adoption over the direct current distribution system.
Fujitsu Ltd. v. Netgear Inc.
Fujitsu Ltd v. Netgear Inc was a patent infringement case centered on three patents claimed to be required for full compliance of the IEEE 802.11 (WiFi) standard and the WiFi Alliance Wireless Multimedia Extensions (WMM) Specification. US patents 4,975,952, 6,018,642, and 6,469,993 were owned by Philips Electronics, Fujitsu, and LG Electronics respectively, and placed in the Via Licensing pool. The Via Licensing pool claimed to hold all patents required for a complete WiFi/WMM implementation. Netgear did not enter an agreement with Via Licensing but produced a series of products that conform to the WiFi standard and WMM Specification.

thats so old, are they hard to ride?

Without a rider, they have no stability, but a proficient unicyclist is more stable than a proficient bicyclist.
Without a rider, unicycles lack stability – however, a proficient unicyclist is usually more stable than a similarly proficient rider on a bicycle as the wheel is not constrained by the linear axis of a frame.

Bicycle and motorcycle dynamics
Bicycle and motorcycle dynamics is the science of the motion of bicycles and motorcycles and their components, due to the forces acting on them. Dynamics falls under a branch of physics known as classical mechanics. Bike motions of interest include balancing, steering, braking, accelerating, suspension activation, and vibration. The study of these motions began in the late 19th century and continues today. Bicycles and motorcycles are both single-track vehicles and so their motions have many fundamental attributes in common and are fundamentally different from and more difficult to study than other wheeled vehicles such as dicycles, tricycles, and quadracycles.
List of Prince George's County Public Schools middle schools
This article provides details on the middle schools within the Prince George's County Public Schools system, in the U.S. State of Maryland. Middle schools operate as either 6th–8th grade middle schools or 7th–8th grade middle schools. Some middle schools are part of combined PreK-8th grade elementary/middle schools, and are referred to as "Academies". Grades 7–9 junior high schools were completely phased out in the mid-1980s. Recent efforts have been made to convert most middle schools to the more popular grades 6–8 model. Issues in the past such as over-enrollment, lack of classroom space, and funding, had made it hard to convert all middle schools to a grades 6–8 configuration, but with increased funding and the addition of new middle schools, the transition is slowly being made.
2011–13 Chilean student protests
The 2011–2013 Chilean protests — known as the Chilean Winter (in particular reference to the massive protests of August 2011) or the Chilean Education Conflict (as labelled in Chilean media) — were a series of student-led protests across Chile, demanding a new framework for education in the country, including more direct state participation in secondary education and an end to the existence of profit in higher education. Currently in Chile, only 45% of high school students study in traditional public schools and most universities are also private. No new public universities have been built since the end of the Chilean transition to democracy in 1990, even though the number of university students has swelled.
List of Kamen Rider Fourze characters

The is a club that Gentaro Kisaragi forms to gain new friends at Amanogawa High School, named after Fourze's predecessors: the various Kamen Riders. The club's members assist Kamen Rider Fourze in his battles against the Zodiarts. In addition, they investigate the urban legends that surround the existence of the past Kamen Riders. The Kamen Rider Club's headquarters are the remains of the lunar base owned by the which developed the Kamen Rider Fourze technology and the Zodiarts Switches.
Armourer
Historically, an armourer is a person who makes personal armour, especially plate armour. In modern terms, an armourer is a member of a military or police force who works in an armoury and maintains and repairs small arms and weapons systems, with some duties resembling those of a civilian gunsmith. With the renewed interest in traditional armour and weaponry, the occupation also involves working with film, stage, and historical and reenactment societies. Period costumes may require reproduction armour, swords, and related equipment. Armourers are the oldest trade in the British Army and trace their heritage back several centuries.
Body broker
A body broker (also non-transplant tissue banks) is a firm or an individual that buys and sells cadavers or human body parts. Whereas the market for organ transplantation is heavily regulated in the United States, the use of cadaver parts for research, training, and other uses is not. Trade in these body parts is performed in a manner akin to raw materials, though many brokers say they charge fees as opposed to selling body parts. Whereas body snatching was a common way of acquiring bodies for research up until the 20th century, modern body brokers usually receive cadavers via body donation. Body brokers often offer free cremation as a means to induce donation from families who are unable to pay funeral costs, returning ashes of part of the body to the next of kin.
