William Liddiard is a transport truck driver based out of London. He is also at the forefront of Liddiard Wheels, an omnidirectional wheel. [1] He invented an omni-directional tyre, which can move a vehicle sideways. [2] [ unreliable source? ]
In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis, with power varying with angle to the axis, declining to zero on the axis. When graphed in three dimensions (see graph) this radiation pattern is often described as doughnut-shaped. This is different from an isotropic antenna, which radiates equal power in all directions, having a spherical radiation pattern. Omnidirectional antennas oriented vertically are widely used for nondirectional antennas on the surface of the Earth because they radiate equally in all horizontal directions, while the power radiated drops off with elevation angle so little radio energy is aimed into the sky or down toward the earth and wasted.
Very High Frequency Omnidirectional Range Station (VOR) is a type of short-range VHF radio navigation system for aircraft, enabling aircraft with a VOR receiver to determine the azimuth, referenced to magnetic north, between the aircraft to/from fixed VOR ground radio beacons. VOR and the first DME(1950) system to provide the slant range distance, were developed in the United States as part of a U.S. civil/military programm for Aeronautical Navigation Aids in 1945. Deployment of VOR and DME(1950) begann in 1949 by the U.S. CAA. ICAO standardized VOR and DME(1950) in 1950 in ICAO Annex ed.1. Frequencies for the use of VOR are standardized in the very high frequency (VHF) band between 108.00 to 117.95 MHz Chapter 3, Table A. To improve azimuth accuracy of VOR even under difficult siting conditions, Doppler VOR (DVOR) were develloped in the 1960s. VOR is according to ICAO rules a primary means navigation system for commercial and general aviation, (D)VOR are gradually decommissioned and replaced by DME-DME RNAV 7.2.3 and satellite based navigation systems such as GPS in the early 21st century. In 2000 there were about 3,000 VOR stations operating around the world, including 1,033 in the US, but by 2013 the number in the US had been reduced to 967. The United States is decommissioning approximately half of its VOR stations and other legacy navigation aids as part of a move to performance-based navigation, while still retaining a "Minimum Operational Network" of VOR stations as a backup to GPS. In 2015, the UK planned to reduce the number of stations from 44 to 19 by 2020.
Omni is a Latin prefix meaning "all" or "every". Omni may also refer to:
The Dodge Omni and the nearly identical badge engineered variant, the Plymouth Horizon, is a subcompact car manufactured and marketed by Chrysler Corporation for model years 1978-1990. The first Chrysler model line produced with front-wheel drive, the Omni and Horizon were also the first front-wheel drive economy cars assembled in the United States. Marketed for eleven years with very few changes, around 2,500,000 Omnis and Horizons were manufactured, with the Plymouth variants more popular than the Dodge-branded models.
A Mecanum wheel is an omnidirectional wheel design for a land-based vehicle to move in any direction. It is sometimes called the Swedish wheel or Ilon wheel after its inventor, Bengt Erland Ilon (1923–2008), who conceived of the concept while working as an engineer with the Swedish company Mecanum AB, and patented it in the United States on November 13, 1972.
Castle Acre Castle and town walls are a set of ruined medieval defences built in the village of Castle Acre, Norfolk. The castle was built soon after the Norman Conquest by William de Warenne, the Earl of Surrey, at the intersection of the River Nar and the Peddars Way. William constructed a motte-and-bailey castle during the 1070s, protected by large earthwork ramparts, with a large country house in the centre of the motte. Soon after, a small community of Cluniac monks were given the castle's chapel in the outer bailey; under William, the second earl, the order was given land and estates to establish Castle Acre Priory alongside the castle. A deer park was created nearby for hunting.
The Drones were an Australian rock band, formed in Perth by mainstay lead vocalist and guitarist Gareth Liddiard in 1997. Fiona Kitschin, his domestic partner, joined on bass guitar and vocals in 2002. Other long-term members include Rui Pereira on bass guitar and then lead guitar; Mike Noga on drums, vocals, harmonica and percussion; and Dan Luscombe on lead guitar, vocals and keyboards. Their second album, Wait Long by the River and the Bodies of Your Enemies Will Float By, won the inaugural Australian Music Prize. In October 2010 their third studio album, Gala Mill was listed at No. 21 in the book, 100 Best Australian Albums. Two of their albums have reached the top 20 on the ARIA Albums Chart, I See Seaweed and Feelin Kinda Free. The group went on hiatus in December 2016 with Kitschin and Liddiard forming a new group, Tropical Fuck Storm, in the following year.
Omnidirectional refers to the notion of existing in every direction. Omnidirectional devices include:
A ball balancing robot also known as a ballbot is a dynamically-stable mobile robot designed to balance on a single spherical wheel. Through its single contact point with the ground, a ballbot is omnidirectional and thus exceptionally agile, maneuverable and organic in motion compared to other ground vehicles. Its dynamic stability enables improved navigability in narrow, crowded and dynamic environments. The ballbot works on the same principle as that of an inverted pendulum.
Omni wheels or poly wheels, similar to Mecanum wheels, are wheels with small discs around the circumference which are perpendicular to the turning direction. The effect is that the wheel can be driven with full force, but will also slide laterally with great ease. These wheels are often employed in holonomic drive systems.
The Suzuki Carry is a kei truck produced by the Japanese automaker Suzuki. The microvan version was originally called the Carry van until 1982 when the passenger van versions were renamed as the Suzuki Every. In Japan, the Carry and Every are kei cars but the Suzuki Every Plus, the bigger version of Every, had a longer bonnet for safety purposes and a larger engine; export market versions and derivatives have been fitted with engines of up to 1.6 liters displacement. They have been sold under myriad different names in several countries, and is the only car to have been offered with Chevrolet as well as Ford badges.
Gareth Liddiard is an Australian musician, best known as a founding member of both The Drones and Tropical Fuck Storm. Musically active since 1997, he also released a solo album titled Strange Tourist in 2010.
In photography, an omnidirectional camera, also known as 360-degree camera, is a camera having a field of view that covers approximately the entire sphere or at least a full circle in the horizontal plane. Omnidirectional cameras are important in areas where large visual field coverage is needed, such as in panoramic photography and robotics.
A ball transfer unit is an omnidirectional load-bearing sphere mounted inside a restraining fixture. They are identical in principle to a computer trackball. Typically the design involves a single large ball supported by smaller ball bearings.
The Virtuix Omni is an omnidirectional treadmill simulator for virtual reality games and other applications. It uses a platform to simulate locomotion i.e. the motion of walking, requiring both special shoes or shoe covers and a surface that reduces friction. It works in conjunction with the HTC Vive, and allows a Vive user to physically walk within a limited number of supported games.
OmniROM is an open-source operating system for smartphones and tablet computers, based on the Android mobile platform. It involves a number of prominent developers from other projects.
The Virtualizer is a series of omnidirectional treadmills for virtual reality applications. The treadmills have integrated sensors for motion detection of the user. The products are being developed, manufactured and sold by the Austrian company Cyberith GmbH.
Explorer 26 was a NASA satellite launched on 21 December 1964, as part of NASA's Explorer program. Its primary mission was to study the Earth's magnetic field.
J.S. Anna Liddiard was an Irish romantic poet whose work draws on themes of patriotism, Irish culture and history, landscape, and human relations.
The ROVR is an omnidirectional treadmill that simulates walking and running in virtual reality when used alongside a head-mounted display.
