Personal Transporter
A personal transporter (also powered transporter, electric rideable, personal light electric vehicle, personal mobility device, etc.) is any of a class of compact, mostly recent (21st century), motorised micromobility vehicle for transporting an individual at speeds that do not normally exceed . They include electric skateboards, kick scooters, self-balancing unicycles and Segways, as well as gasoline-fueled motorised scooters or skateboards, typically using two-stroke engines of less than displacement. Many newer versions use recent advances in vehicle battery and motor-control technologies. They are growing in popularity, and legislators are in the process of determining how these devices should be classified, regulated and accommodated during a period of rapid innovation. Generally 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 motorcycle or moped); and p ...

The park hosts several events, including a seasonal "Winter Village" with an ice rink and shops during the winter. The first park at the site was opened in 1847 and was called Reservoir Square due to its proximity to the Croton Distributing Reservoir. Reservoir Square contained the New York Crystal Palace, which hosted the Exhibition of the Industry of All Nations in 1853 and burned down in 1858. The square was renamed in 1884 for abolitionist and journalist William Cullen B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States International Trade Commission
The United States International Trade Commission (USITC or I.T.C.) is an agency of the United States federal government that advises the legislative and executive branches on matters of trade. It is an independent, bipartisan entity that analyzes trade issues such as tariffs and competitiveness and publishes reports. As a quasi-judicial entity, the USITC investigates the impact of imports on U.S. industries, and directs actions against unfair trade practices, such as subsidies; dumping; and intellectual property infringement, including copyright infringement. Background and statutory authority The USITC was established by the U.S. Congress on September 8, 1916, as the U.S. Tariff Commission.

River Wharfe
The River Wharfe ( ) is a river in Yorkshire, England originating within the Yorkshire Dales National Park. For much of its middle course it is the county boundary between West Yorkshire and North Yorkshire. Its valley is known as Wharfedale. The watercourse first becomes known as the River Wharfe at the confluence of Greenfield Beck and Oughtershaw Beck at Beckermonds. Flowing initially through Langstrothdale, it then passes by, or in some cases through, Kettlewell, Grassington, Bolton Abbey, Addingham, Ilkley, Burley-in-Wharfedale, Otley, Wetherby and Tadcaster. It then flows into the River Ouse near Cawood. The section of the river from its source to around Addingham is in Upper Wharfedale and has a very different character to the river downstream. The Wharfe is long (before it joins the Ouse), making it the 21st longest river in Britain. It is a public navigation from the weir at Tadcaster to its junction with the Ouse near Cawood and is tidal from Ulleskelf to the Ouse ...

Jimi Heselden
James William "Jimi" Heselden OBE (27 March 1948 – 26 September 2010) was a British entrepreneur. A former coal miner, Heselden became wealthy by manufacturing the Hesco bastion barrier system. In 2009, he bought Segway Inc., maker of the Segway personal transport system. Heselden died in 2010 from injuries apparently sustained falling from a cliff while riding his own product. His estate, bequeathed to his widow and family, was worth over £340 million and he was ranked in the top 400 members of the ''Sunday Times Rich List''. Early life Heselden grew up in the Halton Moor district of Leeds, West Yorkshire, England. At the age of 15, Heselden left Osmondthorpe Secondary Modern School to work as a labourer and then at collieries in Temple Newsam and Lofthouse. He lost his job in the wave of redundancies that followed the 1984–85 miners' strike and spent his redundancy money on renting a workshop and, at first, setting up a sandblasting business. He then worked on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regenerative Braking
Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy into a form that can be either used immediately or stored until needed. In this mechanism, the electric traction motor uses the vehicle's momentum to recover energy that would otherwise be lost to the brake discs as heat. This method contrasts with conventional braking systems. In those systems, the excess kinetic energy is converted to unwanted and wasted heat due to friction in the brakes, or with rheostatic brakes, where the energy is recovered by using electric motors as generators but is immediately dissipated as heat in resistors. In addition to improving the overall efficiency of the vehicle, regeneration can significantly extend the life of the braking system as the mechanical parts will not wear out quickly. General principle The most common form of regenerative brake involves an electric motor functioning as an electric generator. In elect ...

Brushless DC Electric Motor
A brushless DC electric motor (BLDC motor or BL motor), also known as an electronically commutated motor (ECM or EC motor) or synchronous DC motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields which effectively rotate in space and which the permanent magnet rotor follows. The controller adjusts the phase and amplitude of the DC current pulses to control the speed and torque of the motor. This control system is an alternative to the mechanical commutator (brushes) used in many conventional electric motors. The construction of a brushless motor system is typically similar to a permanent magnet synchronous motor (PMSM), but can also be a switched reluctance motor, or an induction (asynchronous) motor. They may also use neodymium magnets and be outrunners (the stator is surrounded by the rotor), inrunners (the rotor is surrounded by the stator), or ...

Twist Grip
A twistgrip is a handle that can be twisted to operate a control. It is commonly found as a motorcycle's right handlebar grip to control the throttle, but is sometimes found elsewhere, such as on a bicycle as a gearshift A gear stick (rarely spelled ''gearstick''), gear lever (both UK English), gearshift or shifter (both U.S. English), more formally known as a transmission lever, is a metal lever attached to the transmission of an automobile. The term ''gear sti ..., and in helicopters. History The first use of the twist grip throttle control was on the Roper steam velocipede of 1867-69. Rather than a sleeve that rotated around the handlebar, Sylvester H. Roper's Steam engine, steam motorcycle's entire handlebar rotated, with a dual mode operation. When rotated forward it opened the throttle, and when rotated backwards it applied the spoon brake. ''Motorcycle Consumer News'' design columnist Glynn Kerr said that pioneering this technology was a point in favor of the Roper's ...
