Ebus
Ebus, EBUS, or E-bus may refer to: * Ebus, an intercity bus service in Canada owned by Pacific Western Transportation * EBUS (serial buses), a data-bus communication interface * Electric bus, several types of buses which uses electric power ** Battery electric bus, the most common type of electric bus * Endobronchial ultrasound Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is not different from "normal" (audible) sound in its physical properties, except that humans cannot hear it. This limit varies ...

EBUS (serial Buses)
In building automation, eBUS (energy bus) is a 2-wire digital serial data-bus communication interface used in heating and solar energy appliances, by mainly German manufacturers. It was originally proposed by the Karl Dungs company, and has since been adopted by several other manufacturers. The eBUS interface has also been used by home-automation enthusiasts to connect their domestic solar or heating system to a networked PC for monitoring or remote control. Physical layer The eBUS 2-wire interface is an asynchronous serial port with active-low voltage that exchanges 8-bit bytes with start and (single) stop bits (no parity bit), at a symbol rate of 2400 baud, and can be implemented with a standard UART plus a voltage converter. It differs from the RS-232 interface, from which it is derived, in that the voltage levels were chosen to allow the bus also to supply power to bus participants, that can use a voltage stabilizer to derive an internal 5 V supply: * logical 0 = 9–12 v ...

Pacific Western Transportation
Pacific Western Transportation (also d/b/a P.W. Transportation) provides a variety of bus services in the Canadian provinces of British Columbia, Alberta, Saskatchewan, Ontario and Yukon. Depending on the location, it offers scheduled and chartered school busing, municipal transit and handi-bus services, airport passenger services and local and long distance coach charters. Since 2022, it is a subsidiary of Student Transportation of America. Lines of business Pacific Western Transportation Group of Companies is separated into four operating divisions: The PWT Motor Coach division provides intercity scheduled (retail) as well as commercial charter transportation across Alberta, specialized health transfer service in British Columbia, and airport passenger and charter transfer services in Ontario. The PWT Employee division services Fort McMurray and the Athabasca oil sands in northern Alberta. The PWT Student Transportation division operates in British Columbia, Alberta, Saskat ...

Electric Bus
An electric bus is a bus that is propelled using electric motors as opposed to an internal combustion engine. Electric buses can store the needed electricity on-board, or be fed continuously from an external source. The majority of buses storing electricity are battery electric buses (which this article mostly deals with), where the electric motor obtains energy from an electric vehicle battery, onboard battery pack, although examples of other storage modes do exist, such as the gyrobus which uses flywheel energy storage. When electricity is not stored on board, it is supplied by contact with outside power sources. For example, overhead wires as in the trolleybus, or with a ground-level power supply, or through Inductive charging#Dynamic charging, inductive charging. As of 2019, 99% of all battery electric buses in the world have been deployed in Mainland China, with more than 421,000 buses on the road, which is 17% of China's total bus fleet. For comparison, the United Sta ...

Battery Electric Bus
A battery electric bus is an electric bus that is driven by an electric motor and obtains energy from on-board batteries. Many trolleybuses use batteries as an auxiliary or emergency power source. In 2018, the National Renewable Energy Laboratory (NREL) found that total operating costs per mile of an electric bus fleet and a diesel bus fleet in the United States are about equal. History The London Electrobus Company started running the first ever service of battery-electric buses between London's Victoria station and Liverpool Street on 15 July 1907. However, the weight and inefficiency of batteries meant that other propulsion technology - such as electric trolleybuses or diesel buses - became commonplace. The first battery buses were mostly small, mini- or midi- buses. The improvement of battery technology from around 2010 led to the emergence of the battery bus, including heavier units such as standard buses and articulated buses. China was the first country to int ...
