Hameg
HAMEG Instruments GmbH was a German enterprise specialized in the development and production of laboratory instruments (such as oscilloscopes). The company was located in Mainhausen near Frankfurt, Germany until it was completely integrated in the test & measurement division of Rohde & Schwarz in 2016. As a result, HAMEG as an independent company was closed. History The business was established in 1957 by Karl Hartmann in Frankfurt/Main under the name HAMEG KG. The company name is derived from Hartmann-Messgeräte. The first product was a 5 MHz one channel oscilloscope. In 2005, the company founder retired and the business was acquired by the electronics company Rohde & Schwarz with headquarters in Munich. During that time, the name was changed to HAMEG Instruments GmbH. HAMEG maintained subsidiaries in Chemnitz (product development) and Münchenbernsdorf (PCB assembly) as well as a distribution subsidiary in France (HAMEG Instruments France S.a.r.l.).

Power Supply
A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are separate standalone pieces of equipment, while others are built into the load appliances that they power. Examples of the latter include power supplies found in desktop computers and consumer electronics devices. Other functions that power supplies may perform include limiting the current drawn by the load to safe levels, shutting off the current in the event of an electrical fault, power conditioning to prevent electronic noise or voltage surges on the input from reaching the load, power-factor correction, and storing energy so it can continue to power the load in the event of a temporary interruption in the source power (uninterruptible ...

Mainhausen
Mainhausen is a municipality of over 9,000 in the Offenbach district in the ''Regierungsbezirk'' of Darmstadt in Hesse, Germany. Geography Location Mainhausen is one of 13 towns and communities in the Offenbach district, lying in the southernmost part of Hesse right on the boundary with Bavaria. The community lies on the eastern edge of the Frankfurt Rhine Main Region right on the Main and southeast of the Frankfurt am Main metropolis. Municipal area’s extent The municipal area covers . Neighbouring communities Mainhausen borders in the west and north on the town of Seligenstadt, in the east on the communities of Karlstein, Kleinostheim and Stockstadt am Main (all three in Aschaffenburg district) and in the south on the town of Babenhausen (Darmstadt-Dieburg). Constituent communities Mainhausen’s two ''Ortsteile'' are Mainflingen and Zellhausen; it is the smallest community in the Offenbach district. It came into being in 1977 through the merger of the two current membe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Controller Area Network
A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other's applications without a host computer. It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles to save on copper, but it can also be used in many other contexts. For each device, the data in a frame is transmitted serially but in such a way that if more than one device transmits at the same time, the highest priority device can continue while the others back off. Frames are received by all devices, including by the transmitting device. History Development of the CAN bus started in 1983 at Robert Bosch GmbH. The protocol was officially released in 1986 at the Society of Automotive Engineers (SAE) conference in Detroit, Michigan. The first CAN controller chips were introduced by Intel in 1987, and shortly thereafter by Philips. Released in 1991, the Mercedes-Benz W140 was the first produc ...

TFT LCD
A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display that uses thin-film-transistor technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments. TFT LCDs are used in appliances including television sets, computer monitors, mobile phones, handheld devices, video game systems, personal digital assistants, navigation systems, projectors, and dashboards in automobiles. History In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET. Paul K. Weimer, also of RCA implemented Wallmark's ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crystal display (L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serial Peripheral Interface Bus
The Serial Peripheral Interface (SPI) is a synchronous serial communication interface specification used for short-distance communication, primarily in embedded systems. The interface was developed by Motorola in the mid-1980s and has become a ''de facto'' standard. Typical applications include Secure Digital cards and liquid crystal displays. SPI devices communicate in full duplex mode using a master-slave architecture usually with a single master (though some Atmel and Silabs devices support changing roles on the fly depending on an external (SS) pin). The master (controller) device originates the frame for reading and writing. Multiple slave-devices may be supported through selection with individual chip select (CS), sometimes called slave select (SS) lines. Sometimes SPI is called a ''four-wire'' serial bus, contrasting with three-, two-, and one-wire serial buses. The SPI may be accurately described as a synchronous serial interface, but it is different from the Sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cathode Ray Tube
A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms ( oscilloscope), pictures (television set, computer monitor), radar targets, or other phenomena. A CRT on a television set is commonly called a picture tube. CRTs have also been used as memory devices, in which case the screen is not intended to be visible to an observer. The term ''cathode ray'' was used to describe electron beams when they were first discovered, before it was understood that what was emitted from the cathode was a beam of electrons. In CRT television sets and computer monitors, the entire front area of the tube is scanned repeatedly and systematically in a fixed pattern called a raster. In color devices, an image is produced by controlling the intensity of each of three electron beams, one for each additive primary color (red, green, and bl ...

Local Interconnect Network
LIN (Local Interconnect Network) is a serial network protocol used for communication between components in vehicles. It is a single wire, serial network protocol that supports communications up to 19.2 Kbit/s at a bus length of 40 meters. The need for a cheap serial network arose as the technologies and the facilities implemented in the car grew, while the CAN bus was too expensive to implement for every component in the car. European car manufacturers started using different serial communication technologies, which led to compatibility problems. In the late 1990s, the LIN Consortium was founded by five automakers ( BMW, Volkswagen Group, Audi, Volvo Cars, Mercedes-Benz), with the technologies supplied (networking and hardware expertise) from Volcano Automotive Group and Motorola. The first fully implemented version of the new LIN specification (LIN version 1.3) was published in November 2002. In September 2003, version 2.0 was introduced to expand capabilities and make provisions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Function Generator
In electrical engineering, a function generator is usually a piece of electronic test equipment or software used to generate different types of electrical waveforms over a wide range of frequencies. Some of the most common waveforms produced by the function generator are the sine wave, square wave, triangular wave and sawtooth shapes. These waveforms can be either repetitive or single-shot (which requires an internal or external trigger source).cnx.org - Using a Basic Function Generator 2005-08-21 Another feature included on many function generators is the ability to add a . |
